Definitions
- the present application relates to a biopsy device. More particularly, the present application relates to an endoscopic biopsy device configured to take multiple tissue samples.
- Endoscopic biopsy procedures may be performed with an endoscope and an endoscopic biopsy forceps device.
- the endoscope is a long flexible tube with various optical features allowing for visualization and having a narrow lumen through which the biopsy forceps device is inserted.
- Known biopsy forceps devices for endoscope use include a long flexible cannula having a pair of opposed jaws at the distal end and manual actuation means at the proximal end. Manipulation of the actuation means opens and closes the jaws.
- an operator guides the endoscope to the biopsy site while viewing a video image of the site.
- the operator can position the jaws around a tissue to be sampled and manipulate the actuation means so that the jaws close around the tissue.
- the normal closing action of the jaws may sever a tissue sample and in some cases, the operator may need to apply an additional pulling or closing force to sever a tissue sample.
- the operator must first deliver the jaws to the tissue site via the endoscope lumen, sever the tissue sample with the jaws, withdraw the biopsy forceps device from the endoscope, and open the jaws to collect the single biopsy tissue sample from within.
- the device With the single biopsy embodiment, the device must be repeatedly inserted, actuated, and withdrawn to acquire multiple tissue samples in a one-at-a-time manner.
- suction is used to retrieve the tissue sample while the distal end of the biopsy forceps device remains in the patient.
- a suction passage is added to the biopsy device so that each biopsy sample can be withdrawn out of from the patient and retrieved from outside of the patient without withdrawing the instrument.
- a biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot.
- the second jaw has a lever arm extending rearward from the pivot when the second jaw is closed.
- a wire having an end is connected to the lever arm of the second jaw.

Abstract
A biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot. The second jaw has a lever arm extending rearward from the pivot when the second jaw is closed. A wire having an end is connected to the lever arm of the second jaw. A suction tube is disposed between the first and second jaw.
Description
- This application claims priority to U.S. Provisional Application No. 61/317,036 filed Mar. 24, 2010, the entirety of which is incorporated herein.
- The present application relates to a biopsy device. More particularly, the present application relates to an endoscopic biopsy device configured to take multiple tissue samples.
- Endoscopic biopsy procedures may be performed with an endoscope and an endoscopic biopsy forceps device. The endoscope is a long flexible tube with various optical features allowing for visualization and having a narrow lumen through which the biopsy forceps device is inserted. Known biopsy forceps devices for endoscope use include a long flexible cannula having a pair of opposed jaws at the distal end and manual actuation means at the proximal end. Manipulation of the actuation means opens and closes the jaws.
- During a biopsy tissue sampling operation, an operator guides the endoscope to the biopsy site while viewing a video image of the site. When the device is inserted into the endoscope with the opposed jaws extending from the narrow lumen of the scope, the operator can position the jaws around a tissue to be sampled and manipulate the actuation means so that the jaws close around the tissue. The normal closing action of the jaws may sever a tissue sample and in some cases, the operator may need to apply an additional pulling or closing force to sever a tissue sample. In one known single biopsy embodiment, the operator must first deliver the jaws to the tissue site via the endoscope lumen, sever the tissue sample with the jaws, withdraw the biopsy forceps device from the endoscope, and open the jaws to collect the single biopsy tissue sample from within.
- With the single biopsy embodiment, the device must be repeatedly inserted, actuated, and withdrawn to acquire multiple tissue samples in a one-at-a-time manner. In another known embodiment of a multiple biopsy device, suction is used to retrieve the tissue sample while the distal end of the biopsy forceps device remains in the patient. In yet another embodiment, a suction passage is added to the biopsy device so that each biopsy sample can be withdrawn out of from the patient and retrieved from outside of the patient without withdrawing the instrument.
- A biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot. The second jaw has a lever arm extending rearward from the pivot when the second jaw is closed. A wire having an end is connected to the lever arm of the second jaw. A suction tube is disposed between the first and second jaw.
- In the accompanying drawings, structures are illustrated that, together with the detailed description provided below, describe exemplary embodiments of the claimed invention.
- In the drawings and description that follows, like elements are identified with the same reference numerals. The drawings are not to scale, and the proportion of certain elements may be exaggerated for the purpose of illustration.

FIG. 15 is a cross-section of another alternative embodiment of a biopsy forceps device, taking a biopsy sample. -
FIG. 1 is a perspective view of one embodiment of anendoscopic biopsy assembly 100. Theendoscopic biopsy assembly 100 is for use with an endoscope (not shown) and includes abiopsy forceps device 200 disposed therein. The endoscope may be any known endoscope. In one known embodiment, the endoscope is an Olympus 160-series endoscope. - A
catheter 205 is operatively connected to thebiopsy forceps device 200, and passes through the endoscope and aconnector 300, to asample collection chamber 105. In the illustrated embodiment, the collection chamber includes atube 110, having an aperture for receiving atray 115 with a handle. Thetray 115 may be slidably removed from the aperture. In one embodiment, thetray 115 may be held in place by a locking mechanism (not shown). Such a locking mechanism may include a pivoting or flexible member and a projection that is received in an aperture of the handle of thetray 115. - In the illustrated embodiment, the
tray 115 has a single sample receiving surface. In an alternative embodiment (not shown), the tray includes one or more dividers that define a plurality of sample receiving surfaces. The dividers may be walls that extend upwards from a bottom surface of the tray, or the dividers may be indentations formed in the bottom surface of the tray. Such a tray may be moved within thesample collection chamber 105, such as by sliding, pivoting, or rotating, to receive samples on the different sample receiving surfaces. - Alternatively, the
sample collection chamber 105 may be any existing collection chamber. In one known embodiment (not shown), thesample collection chamber 105 is a polypectomy trap adapter commercially available under the name ETRAP polyp trap and sold by U.S. Endoscopy. Thesample collection chamber 105 may include multiple components constructed of polymeric materials, such as thermoplastic elastomers or clear rigid plastic. - An actuation handle 400 is also operatively connected to the
biopsy forceps device 200 throughconnector 300. As will be described in further detail below, theactuation handle 400 includes a sliding member and a shaft. The sliding member may be manually translated along the shaft, which causes thebiopsy forceps device 200 to open and close. The actuation handle 400 may be constructed of metal or a polymeric material, such as acrylonitrile butadiene styrene (“ABS”) plastic. - In the illustrated embodiment, the
sample collection chamber 105,connector 300, and actuation handle 400 are spaced from each other. In alternative embodiments (not shown) one or more of thesample collection chamber 105,connector 300, and actuation handle 400 may be directly attached to each other. Such attachments may be permanent attachments or releasable attachments. For example, in one embodiment (not shown), thesample collection chamber 105 is fixedly or releasably attached to theactuation handle 400. In another embodiment (not shown), thesample collection chamber 105 is releasably attached to theconnector 300. In yet another embodiment, theconnector 300 is releasably attached to theactuation handle 400. Releasable attachments may be formed by clips, VELCRO, snaps, threaded connectors, or other known releasable connectors. Fixed attachments may be formed by adhesive, bolts, rivets, welds, and other known fixed connectors. A fixed attachment may also be formed by molding two or more components as a single component. - In the illustrated embodiment, a suction device (not shown) is connected to a suction end S of a tube T, and the tube T is operatively connected to the
sample collection chamber 105. A valve V is disposed along tube T. When the suction device is turned on and the valve V is open, suction is applied through the tube T, and through thesample collection chamber 105 andcatheter 205 to the distal end of thebiopsy forceps device 200. Thetray 115 in thesample collection chamber 105 includes a plurality of apertures, so as not to interrupt suction along the tube T to thebiopsy forceps device 200. When the suction device is turned on and the valve V is closed, suction is only applied through a portion of the tube T. - In the illustrated embodiment, the valve V is biased in a closed position and is opened by a manually operated push button. In the illustrated embodiment, the valve is a trumpet valve. In an alternative embodiment (not shown), the valve is opened by a foot pump or a clamp. In another alternative embodiment (not shown) the valve is disposed on the
sample collection chamber 105 or thecatheter 205. - In operation, the operator guides the endoscope to the biopsy site while viewing the biopsy site through various optical features allowing for visualization. The operator positions the
biopsy forceps device 200 at a desired location and actuates theactuation handle 400 to open thebiopsy forceps device 200. The operator optionally applies suction through thebiopsy forceps device 200 by opening the valve V. Applying suction at this time may cause “tenting” of the tissue, thus facilitating the taking of a sample. The operator then actuates theactuation handle 400 to close thebiopsy forceps device 200 around a tissue sample. The act of closing thebiopsy forceps device 200 may sever the tissue sample in some instances. In other instances, the operator may need to apply force to withdraw thebiopsy forceps device 200 from the biopsy site. This additional force may help to sever the tissue sample from the site. After the sample has been severed, if the valve V has not been previously opened, the operator opens the valve V to apply suction. The suction evacuates the sample from thebiopsy forceps device 200 and draws it through thecatheter 205 to thesample collection chamber 105. The valve V may be opened before or after theactuation handle 400 is actuated. - The
endoscopic biopsy assembly 100 may be operated by one or more operators. For example, a first operator may guide the endoscope, a second operator may actuate theactuation handle 400, a third operator may open and close the valve V, and a fourth operator may retrieve the tissue sample from thesample collection chamber 105. Alternatively, a single operator may perform each of these tasks. As another alternative, two or three operators may operate theendoscopic biopsy assembly 100, with each operator performing one or more tasks. -
FIGS. 2A and 2B illustrate first and second perspective views of thebiopsy forceps device 200 connected to acatheter 205. Thebiopsy forceps device 200 includes astationary jaw 210 havingfenestration 215 andmovable jaw 220 also havingfenestration 225. In alternative embodiments (not shown), thestationary jaw 210,movable jaw 220, or both are solid and do not include fenestrations. In another alternative embodiment (not shown), but jaws are movable. -
FIGS. 2C and 2D illustrate top plan views of themovable jaw 220 and thestationary jaw 210. Referring now toFIGS. 2A-D , each of thestationary jaw 210 andmovable jaw 220 have sharpened edges configured to cut tissue. The sharpened edges may be continuous edges or serrated edges. In the illustrated embodiment, each of thestationary jaw 210 andmovable jaw 220 have a radial curve and are cup shaped. In alternative embodiments (not shown), the jaws may have non-radial curves, or straight edges that form a geometric shape. - Each of the
stationary jaw 210 andmovable jaw 220 may be formed by a metal injection molding (“MIM”) or other processes including, but not limited to, stamping, laser welding, sintering, and molding. The jaws may be constructed of stainless steel, aluminum, titanium, ceramics, plastics, or other known materials. - The
catheter 205 may be constructed of a polymeric material, such as TEFLON, polyethylene, polypropylene, nylon, polyetherether keytone (PEEK), and other polymeric materials. Thecatheter 205 may be formed by an extrusion process. - The
movable jaw 220 is connected to thestationary jaw 210 by apivot 230. In the illustrated embodiment, thepivot 230 includes two posts that extend from themovable jaw 220 and are seated in corresponding apertures of thestationary jaw 210. In an alternative embodiment (not shown), thepivot 230 includes two posts that extend from thestationary jaw 210 and are seated in corresponding apertures of themovable jaw 220. In another alternative embodiment (not shown), both thestationary jaw 210 and themovable jaw 220 include a pair of corresponding apertures, and a pin is inserted therein to form a pivot. In each such embodiment, the pivot may be positioned so as not to interfere with a passageway for tissue samples. In such embodiments, the pivot may be described as an external pivot. Alternatively, the pivot may cross such a passageway. - The
biopsy forceps device 200 further includessuction tubing 235 having a first end disposed within the chamber formed bystationary jaw 210 andmovable jaw 220. In the illustrated embodiment, the end of thesuction tubing 235 is positioned forward of thepivot 230, such that when themovable jaw 220 is opened, the first end of thesuction tubing 235 may directly contact tissue. An operator may choose to apply suction prior to taking a tissue sample, such that when the valve V is open and suction is applied through thesuction tubing 235, the tissue that is in direct contact with thesuction tubing 235 is raised. This may be referred to as “tenting.” The tenting process pulls tissue between the jaws, so that when themovable jaw 220 is closed, the sharpened edges of the jaws may sever the tented tissue and capture a sample between the jaws. An additional backwards force may also be required to sever the tissue sample. The tissue sample is subsequently drawn down the catheter by the applied suction. - In one embodiment, the
suction tubing 235 is an insert that extends partially into the catheter. In an alternative embodiment, thesuction tubing 235 extends the length of the catheter. - The
movable jaw 220 further includes alever arm 240 having anaperture 245. Awire 250 engages thelever arm 240 through theaperture 245, such that manipulation of thewire 250 moves thelever arm 240 about thepivot 230, causing themovable jaw 220 to open and close. Thewire 250 may be manipulated through theactuation handle 400. -
FIG. 3 illustrates a cross-section of thebiopsy forceps device 200. As can be seen in this view, thestationary jaw 210 further includes aledge 255 disposed opposite the cutting surface of thestationary jaw 210. Theledge 255 may be created during the manufacturing process to form apertures in thestationary jaw 210 to accept the posts of themovable jaw 220. In one embodiment, a staking operation is performed to bend theledge 255. In the illustrated embodiment, theledge 255 forms a stop, thereby defining the arc through which themovable jaw 220 may pivot. Alternatively, theledge 255 may be dimensioned so as not to interfere with the pivoting of themovable jaw 220. - With continued reference to
FIG. 3 , theaperture 245 in thelever arm 240 forms a socket that engages aball 260 at the end of thewire 250. During the manufacturing process, the outer edges of theaperture 245 may be crimped or otherwise closed around theball 260 after the wire is received, such that the ball will remain housed in the socket formed byaperture 245 during operation of theendoscopic biopsy assembly 100. In one embodiment, a staking operation is performed to secure theball 260 in the socket. In an alternative embodiment (not shown), a stop is formed on the wire on the opposite side of the lever arm, such that the lever arm is sandwiched between theball 260 and the stop. - In the illustrated embodiment, the distal end of the
suction tubing 235 is slightly spaced from the distal end of thejaws suction tubing 235 may be positioned adjacent the distal end of thejaws suction tubing 235 may be further spaced from the distal end of thejaws suction tubing 235 is below theball 260 of thewire 250. In one known embodiment, the position of thesuction tubing 235 may be varied before or during an operation. -
FIG. 4 illustrates a partial perspective view of one embodiment of acatheter assembly 270. In this embodiment, the catheter assembly includes thecatheter 205 andsuction tubing 235. Thesuction tubing 235 may be a separate component or it may be integral with thecatheter 205. Thecatheter 205 may be constructed of a polymeric material such as polytetrafluoroethylene (“PTFE”). Thesuction 235 tubing may also be constructed of a polymeric material such as PTFE. - The center of the
suction tubing 235 is ahollow passageway 265 through which tissue samples may be drawn. Thehollow passageway 265 is operatively connected to the suction device, such that when the suction device is turned on and the valve V is open, suction will be applied to thepassageway 265 and draws a severed tissue sample to thecapture container 105. - In the illustrated embodiment, the
catheter 205 further includes a pair oflumens 275 a,b configured to receive thewire 250. Although only one of the lumens (275 a) is used, two lumens are formed for manufacturing purposes. Additionally, a pair ofcorresponding grooves 280 a,b are formed on thesuction tubing 235. Thegrooves 280 a,b may extend the entire length of thesuction tubing 235, or may only extend along a portion of thesuction tubing 235. Thecorresponding grooves 280 a,b are aligned with thelumens 275 a,b and may restrict lateral movement of thewire 250. The inclusion of a lumen 275 for thewire 250 that is separate from thepassageway 235 ensures that the tissue sample has a clear travel path to thecollection chamber 105. However, it should be understood that the lumen 275 is optional and that the wire may be disposed along thepassageway 235. - Additionally, the
catheter 205 includes a pair ofnotches 285 a,b or other apertures configured to receivetangs 290 of the stationary jaw 210 (as shown inFIG. 2D ). Thenotches 285 a,b may extend for a portion of thecatheter 205, or they may extend the entire length of thecatheter 205. During assembly of thebiopsy forceps device 200, adhesive may be placed in thenotches 285 a,b such that the jaws are thereby affixed to thecatheter 205. Where adhesive is to be used, the surface may be scored to aid in bonding. Thenotches 285 a,b serve as an anchor point for the base of thestationary jaw 210 and prevents the jaws from rotating relative to the catheter. - In an alternative embodiment (not shown), the
notches 285 a,b are replaced with an annular groove configured to receive a flange of the jaws. In another alternative embodiment (not shown), the catheter does not include notches or a groove, and the jaws are glued, welded, or otherwise affixed to the catheter. -
FIG. 5 illustrates a perspective view of an alternative embodiment of acatheter assembly 500. In this embodiment, the catheter assembly includes thecatheter 505 andsuction tubing 510, wherein thesuction tubing 510 is a separate insert that is received in ahollow passageway 515 of thecatheter 505. The center of thesuction tubing 510 is also ahollow passageway 520 for tissue samples. - In the illustrated embodiment, the
catheter 505 further includes alumen 525 configured to receive a wire. The inclusion of alumen 525 for the wire ensures that the tissue sample has a clear travel path to thecollection chamber 105. -
FIG. 6 illustrates a front view of an alternative embodiment of a catheter.Catheter 605 may be employed incatheter assembly catheter 605 includes ahollow passageway 610. Thecatheter 605 does not include any lumens for a wire. Instead, the wire may be disposed along thepassageway 610. -
FIG. 7 illustrates a side view of one embodiment of aconnector 300 and actuation handle 400 of theendoscopic biopsy assembly 100. Theconnector 300 is a substantially “y-shaped” component, having amajor chamber 305 and aminor chamber 310. Thecatheter 205 passes through themajor chamber 305 to thesample collection chamber 105. Acable 315 leads from theminor chamber 310 to theactuation handle 400. - The actuation handle 400 includes a
shaft 405 having adistal end 410 and aproximal end 415. In the illustrated embodiment, theproximal end 415 has afirst ring 420 attached thereto. Thefirst ring 420 is configured to receive an operator's thumb or finger. However, it should be understood that the ring may be omitted or replaced with a transversely oriented member. - A sliding
member 425 is slidably mounted to theshaft 405. In the illustrated embodiment, the slidingmember 425 includes asecond ring 430 and athird ring 435, each configured to receive an operator's finger or thumb. Alternatively, the slidingmember 425 may be a spool, or include a transversely oriented member in lieu of rings. - A proximal end of the
wire 250 is fixedly attached to the slidingmember 425. When the sliding member is translated towards theproximal end 415 of theshaft 405, thewire 250 is refracted. This retraction causes theball 260 at the opposite end of thewire 250 to pull thelever arm 240 of themovable jaw 220, which causes themovable jaw 220 to pivot towards the closed position. Likewise, when the sliding member is translated towards thedistal end 410 of theshaft 405, thewire 250 is pushed forward. This movement causes theball 260 at the opposite end of thewire 250 to push thelever arm 240 of themovable jaw 220, which causes themovable jaw 220 to pivot towards the open position. -
FIG. 8 illustrates a perspective view of assembled connecting components disposed within theconnector 300. In this embodiment, thecatheter 205 connected to thebiopsy forceps device 200 includes afirst catheter 205 a and asecond catheter 205 b. End portions of each of the first andsecond catheters 205 a,b are disposed in an aligningmember 320. The aligningmember 320 is a hollow rod having an elongated cavity to receive the first andsecond catheters 205 a,b. The aligningmember 320 further includes aside opening 325. In the illustrated embodiment, theside opening 325 is formed by a chamfer extending downwards to the cavity and outwards to an end of the aligningmember 320. In an alternative embodiment (not shown), the side opening may extend the entire length of the aligningmember 320. In another alternative embodiment (not shown), the side opening may be a hole or slot that does not extend to an end of the aligningmember 320. - The connecting components may be assembled in the following manner. A first end of the
first catheter 205 a is inserted into a first end of the aligningmember 320. Thefirst catheter 205 a may be affixed in its position with adhesive, or by a press fit. The first end of thefirst catheter 205 a includes anotch 330 that provides an exit for thecable 315. Thefirst catheter 205 a is positioned such that thenotch 330 and thecable 315 are accessible through theside opening 325 of the aligningmember 320. In the illustrated embodiment, a flap of the catheter remains in place over thenotch 330. This flap may shield the wire from adhesive that is applied during assembly. - A first end of the
second catheter 205 b is then inserted into a second end of the aligningmember 320, such that it abuts the first end of thefirst catheter 205 a. Thesecond catheter 205 b may be affixed in its position with an adhesive or by a press fit. -
FIG. 9 illustrates a cross-section of theconnector 300. As explained above, the first andsecond catheters 205 a,b pass through themajor chamber 305 of theconnector 300. A firstouter tube 335 surrounds thecatheter 205 at a front end of themajor chamber 305, forward from the aligningmember 320. A secondouter tube 340 surrounds thecatheter 205 at a rear end of themajor chamber 305. The first and secondouter tubes catheter 205 near theconnector 300. In an alternative embodiment (not shown), a single outer tube may extend through theentire connector 300. In another alternative embodiment (not shown), no outer tubes are included. - As further explained above, a
cable 315 extends from theminor chamber 310. A portion of thecable 315 is shown in cutaway for illustrative purposes. Thecable 315 may be a sheathspring having tubing 345 disposed therein. In one embodiment, thetubing 345 is PEEK tubing. Thewire 250 is disposed within thecable 315. Thewire 250 extends from the slidingmember 425 of theactuation handle 400, through thecable 315 and theminor chamber 310, and joins thecatheter 205 inside themajor chamber 305 of theconnector 300. Thewire 250 either extends through a lumen or the hollow passageway in thecatheter 205. Thecable 315 may act as a dampener that prevents the slidingmember 425 of the actuation handle 400 from being translated too quickly or violently. - In the illustrated embodiment, the
minor chamber 310 extends from themajor chamber 305 at an angle of approximately 15°. In alternative embodiment, theminor chamber 310 may extend from the major chamber at an angle between 5° and 60°. A smaller angle may be preferable to prevent crimping of thewire 250. - In the illustrated embodiment, the
major chamber 305 also includes asterilization hole 350. Thesterilization hole 350 is configured to receive sterilizing material, such as ethylene oxide, as may be needed or desired. -
FIG. 10 illustrates a partial cross-section of an alternative embodiment of aconnector 700 of an endoscopic biopsy assembly. Theconnector 700 is substantially the same as theconnector 300, except for the differences described herein. Like reference numbers indicate like components. Theconnector 700 includes amajor chamber 705 having anenlarged cavity portion 710 sized to accept ahousing 715. Thehousing 715 surrounds portions of the aligningmember 320, thefirst catheter 205 a, and thesecond catheter 205 b. -
FIG. 11 illustrates a perspective view of thehousing 715. Thehousing 715 has a throughhole 720 and tapered ends 725, 730, and may form a seal around the enclosed components. As best shown inFIG. 10 , a distal end of thehousing 715 surrounds a cylindrical distal end of aligningmember 320 to create a seal therewith. If desired, small gaps or clearances can be filled with adhesive, grease, sealing compounds and the like to create an air-tight seal. A proximal end of aligningmember 320 includes the side opening 325 (seeFIG. 8 ). Theside opening 325 creates a gap betweenhousing 715 andsecond catheter 205 b for the passage of an “S” portion ofcable 315. While not shown, the gap may be filled around thecable 315 with a seal 316 such as an elastomeric seal or adhesive. Thecable 315 may also be lubricated to prevent sticking with the seal 316. In an alternative embodiment (not shown), the ends of the housing are straight. - The
housing 715 may be constructed of a polymeric material such as but not limited to ABS or any one of a number of metals. In one embodiment, thehousing 715 is constructed at least partially of rubber to aid in sealing the enclosed components. In an alternative embodiment (not shown), o-rings or other seals may be disposed within the housing. -
FIG. 12 illustrates a perspective view of an alternative embodiment of anendoscopic biopsy assembly 800. Theendoscopic biopsy assembly 800 is substantially the same as theendoscopic biopsy assembly 100 shown inFIG. 1 , except for the differences described herein. Like reference numbers indicate like components. - The
endoscopic biopsy assembly 800 includes a radio frequency (RF)generator 805 connected to theactuation handle 400. In this embodiment, at least one of thejaws RF generator 805 is in electrical communication with the electrically conductive jaw. In one particular embodiment, bothjaws FIG. 12 , handle 400 includes an RF connector socket positioned distal to a dual ring portion of the handle. The RF connector socket is electrically connected to thejaws least wire 250 for the delivery of RF energy to the jaws. - In this embodiment, the
RF generator 805 is in electrical communication with at least one of thejaws wire 250. TheRF generator 805 is also in electrical communication with anactuator 810 that is used by the surgeon to deliver RF energy when required. When the actuator is activated, RF energy is provided to at least one of thejaws RF generator 805 may include a wave form selection switch (not shown) that allows an operator to select between a cauterizing waveform and a cutting waveform. In the illustrated embodiment, theactuator 810 is a foot pedal. However, it should be understood that any actuator may be employed, such as buttons, dials, and switches. - In the illustrated embodiment, the
RF generator 805 has a first pole 815 (i.e., a positive pole) and a second pole 820 (i.e., a negative pole or a ground pole). In the illustrated embodiment, only thefirst pole 815 is in electrical communication with at least one of thejaws second pole 820 is connected to aground pad 825. Thepad 825 is placed under the patient to form an electrical ground between the patient and theRF generator 805. In alternative embodiments (not shown), thesecond pole 820 may be in electrical communication with any conductive object that can contact or be placed proximal to a patient. - In an alternative embodiment (not shown), both positive and negative poles are in electrical communication with the
jaws second poles jaw 210 through a first wire, and the opposite pole is in electrical communication withjaw 220 through a second wire. Such an embodiment will electrically isolate eachjaw isolated jaw - For the bipolar embodiment, each
jaw jaw 210 orjaw 220 at the wire contact area, and to tissue through the exposed horseshoe shaped tissue biting area. Such an embodiment may also deliver more focused energy that would not interfere with other electrical devices, such as a pacemaker in a patient. -
FIGS. 13A-C illustrate cross-sections of thebiopsy forceps device 200 of the alternative embodiment of theendoscopic biopsy assembly 800, at various stages of taking a biopsy sample. - In
FIG. 13A , thebiopsy forceps device 200 has been positioned at a desired location, thejaws jaws suction tubing 235, which causes “tenting” or drawing of the tissue at least partially into thesuction tubing 235 as shown. If desired, a larger bite of tissue can be taken by pushing thejaws - In
FIG. 13B , the operator has actuated theactuation handle 400 to close thejaws biopsy forceps device 200 around a tissue sample as it is being tented and drawn into thesuction tubing 235. The act of closing thebiopsy forceps device 200 pinches the “tented” tissue at the base of the polyp and in this view has fully severed the tissue sample just before it is drawn farther into thesuction tubing 235 by the applied suction. In other instances, the tissue sample may not be severed entirely between thejaws - In
FIG. 13C , the closing of the jaws has failed to sever the tissue sample and, the operator is activating the RF generator to apply monopolar RF energy at the jaws to cauterize the tissue around the site. The operator may select a cauterizing wave form, such as a square wave, prior to activating the RF generator. Cauterizing the site in this manner may staunch bleeding caused by the severing, and may also kill cancer cells at the site. Because the un-severed sample is inside of the jaws, it is prevented from contacting the negatively charged patient and is not burned when the RF energy is applied. The tissue cannot be coagulated because it is exposed to only positive RF energy which travels along the external skin of the jaws and to the negatively charged patient. After applying RF energy, the operator elects to pull and shake the tissue sample free so that it can be sucked into thesuction tubing 235 -
FIG. 14 illustrates a cross-section of thebiopsy forceps device 200 as it extends from a distal end of anendoscope 900, while taking a biopsy sample. Thebiopsy forceps device 200 is the same asbiopsy forceps device 200 shown inFIGS. 1-3 , except for the placement within theendoscope 900. Like reference numbers indicate like components. - The
endoscope 900 has atube 905 that includes afirst lumen 915 that is configured to receive thebiopsy forceps device 200.Catheter 205 is shown extending along thefirst lumen 915 ofendoscope 900 with thejaws endoscope 910.Endoscope 900 further comprises asecond lumen 910 in communication with a fluid source for providing irrigation to tissue and to thejaws suction tubing 235 and the operator may irrigate the surgical site by providing fluid through thesecond lumen 915 of theendoscope 900. The fluid may be used to clean the biopsy site or used to wash the accumulated tissue samples through thesuction tubing 235. The fluid may enter thebiopsy forceps device 200 through thefenestrations jaws suction tubing 235 when suction is applied, and may aid in washing or drawing the tissue sample down thesuction tubing 235. Exemplary fluids may include water, saline, drugs or any combination thereof. -
FIG. 15 illustrates a cross-section of thebiopsy forceps device 200 as it extends from theendoscope 900. In this view, suction is being applied to draw a stuck tissue sample down thesuction tubing 235. If the suction has failed to dislodge the stuck biopsy sample, the operator can open and close thejaws actuation handle 400. Repeating this opening and closing action causes thewire 250 to move longitudinally within thesuction tubing 235 which may then rubwire 250 against the tissue sample and aid in drawing it through thesuction tubing 235. This method may be effective in dislodging a tissue sample that has become stuck, and may be performed with or without irrigation. - It should be understood that in various embodiments, many elements of the
endoscopic biopsy assembly 100 can be operably configured to be flexible such as, for example, but not limited to:catheter 205,suction tubing 210,suction tubing 235,wire 250,cable 315,tubing 345, andcatheter 505. Alternately, one or more of the flexible elements can be substantially rigid such asexemplary catheter 205 or any other element ofassembly 100. - To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” Furthermore, to the extent the term “connect” is used in the specification or claims, it is intended to mean not only “directly connected to,” but also “indirectly connected to” such as connected through another component or components.
- While the present application has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the application, in its broader aspects, is not limited to the specific details, the representative apparatus and method, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's general inventive concept.
