COLUMBIA PLANOORAPH CO..WASH|NGTON, D. c.
1 ohms CHARLES EDMUND KELLS, or NEW ORLEANS, LOUISIANA;
TROGAB.,
' To all whom it may concern:
Be it known that I, CHARLES EDMUND KnL'Ls, a citizen of-the UnitedStates, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Trocars, of which the following is a specification.
This invention relates to surgical instrumentsof the kind called trocars which are used for withdrawing fluids of various kinds from the body, such as pusfrom a sac containing it. Trocars ordinarily comprise a lance or similar device used to puncture the sac 01' other part of the body and a tube or barrel in which the lance is inclosed and in which it is mounted to reciprocate in such manner that it may be drawn into the barrel or projected therefrom to pierce the sac or other fluid-containing part of ,the body. The tube or barrel is usually connected with a pump or other vacuum-producing device which serves to draw the pus or other fluid from the pierced part and causes it to pass into and through the barrel to a suitable receptacle. I have'found that in the use of such instruments the fluid withdrawn from the body often leaks past the end of the barrel of the instrument and re'e'nters the body or passes into some cavity of the body adjacent to the part pierced. This is not only objectionable but is often dangerous.
The object of my invention is to overcome this fault, and I preferably do it by providing a sheath which surrounds the lower part of the barrel and is adapted to fit tightly against the sac or other part pierced by the lance in such mannerv as'to' prevent the escape of fluid from the instrument. The interior of the sheath communicates with the interior of the trocar barrel through an opening in the latter, and the arrangement is such that any extracted fluid which leaks past the end of the trocar bar- ,rcl is caught by the sheath through which sheath is madeadjustable to accommodate the part to which it is applied, and to make a close contact therewith.
I may also embody my invention in an in- Specification of Letters'Patent. Patented hfly 20, 1915, Application filed February 8, 1915. Serial No. 6,781.
strument in which a puncturing device is mounted to reciprocate in a barrel connected wlth a vacuum-produclng apparatus,
and in which the puncturing device is made hollow, a chamber therein'connecting by a lateral opening with the interior of the barrel, the arrangement being such that the inner end of the barrel may be placed in close contact with the partto be treated and any liquid which leaks past the interiorof the puncturing devicemay be drawn .into the barrel around the outside of thepuncturing instrument.
In the accompanying drawings: Figure 1 shows a longitudinal central section through a trocar, embodying my improvements and showing how it is applied to the body on which it operates, and before the lance has been projecteda Fig. 2 is a similar view, showing how the lance is made to pierce the part operated upon. Fig. 3 is a similar view, showing how the trocar barrel is made to enter the puncture made" by the lance. Fig. lisa'view'on an enlarged scale, and in end elevation of the preferred form of lance. Fig. 5 shows a longitudinal central section through a modified form of the in- 1 vention. Fig. 6 is a detail view of some of the parts shown in Fig. 5. Fig. 7 shows a longitudinal section of a modification.
The barrel A of the trocar may be of any suitable construction and of any suitable material. Near its'outer end it is provided with a branch tube B which may be connected with any suitable vacuum-producing apparatus. The lance or puncturing device 0 may also be of any suitable form, its stem or rod 0 being passed through a cap applied-'tothe outer endof the barrel having preferably a threaded and packed connection therewitlnas shown. The stem is provided'with a handle 0 by the lance may beo'perated. a ".As thus fardescribed the trocar is of usual construction, but as before stated when such an instrument is'used there is apt to be leakage at 00 past the end of the barrel, and the fluid. thus escaping is apt to enter some adjacent partof 'thenbod'y and cause blood poisoning or other injury. In order to prevent this I provide the trocar. with a sheath Dwhich may be made of any suitable material and which is preferably bell shaped as shown, and has a tight fitting but sliding connection at d with the barrel. The construction is such as to leave a chamber (1 means of which the branch tube B.
between the sheath and the barrel while the outer edge of the sheath is adapted to make close fluid-tight connection with the body X operated upon. The outer end of the barrel is so formed that it may be passed through the puncture made by the lance and enter the cavity, in the manner indicated in Fig. 3. In order to establish connection between the chamber d of the sheath and the interior of the barrel a hole (Z is made in the latter so that fluid caught in the sheath may pass therefrom into the barrel and thence pass through it with the fluid directly entering the barrel.
In use the instrument is applied to the body in the manner indicated in Fig. 1, the point of the lance being within the trocar barrel, the outer end of the barrel being in contact with the part to be pierced and the outer edge of the sheath being pressed against the body, as indicated, so as to make a close fluid-tight connection therewith. When this is done the lance is pushed into the part treated and made to pierce it in the manner shown in Fig. 2. Directly after this the trocar is pushed inward to a slightly greater extent until the inner end of the trocar barrel enters the puncture, in the manner indicated in Fig. 3, the trocar barrel at this time sliding through the oint with the sheath at (Z. Most of the pus or other fluid in the sac or other part treated is drawn through the trocar barrel and out through Any fluid that leaks or escapes at as and passes to the outside of the trocar barrel will be arrested or caught by the sheath D and will be drawn through the opening d in the barrel and pass out through the latter.
It will be understood that as soon as the parts are adjusted to the position shown in Fig. 1 the vacuumproducing apparatus is started and continues to act until the operation is completed. 1 have stated that any suitable form of lance or puncturing device may be used, but preferably the lance is of the kind illustrated in order that the fluid may readily pass by way of the grooves c to the trocar barrel. Instead of providing the trocar barrel. with a branch tube B, I may provide the lance C, as shown in Fig. 5, with a tubular or hollow stem F, having at its outer end a part Gr which may serve as a handle and with which the vacuum producing apparatus may be connected, otherwise the instrument is similar to that before described, except that in this case the lance 0 is hollow and is provided with openings g, g for establishing communication between the outside of the lance and the interior of the tube 13.
The details of construction may be further varied without departing from my invention which consists broadly in providing some means for preventing the escape of fluid from the trocar.
, In Fig. 7 I have shown an instrument consisting of a barrel end having a branch pipe on adapted to connect with a vacuumproducing apparatus, and a puncturing instrument N having a stem n passing through a packed cap 0. The inner portion of the puncturing instrument is hollow, as shown, and communicates with the interior of the barrel through a hole 0. The inner end of the trocar may be placed in close contact with the parts to be treated, and the vacuumproducing apparatus started. Then the puncturing instrument is pushed inward, and most of the fluid extracted is drawn through the chamber 00 and through the hole 0 into the barrel and thence through the branch pipe m. As shown, however, there is a space 12 between the barrel and the puncturing instrument, and any liquid which does not enter the interior of the instrument or leaks past it is caught or arrested and drawn through the space 3 into the barrel. Such an instrument may be used with facility, although the instrument hereinbefore described is preferred.
I claim as my invention 1. A trocar, comprising a barrel, a lance mounted to reciprocate therein, means for conducting fluid from the part pierced by the lance, a sheath surrounding the inner end of the barrel, and a communication be tween the interior of the sheath and the barrel.
2. A trocar, comprising a barrel, a hollow puncturing device mounted to reciprocate therein, and means for withdrawing liquid from the part treated through both the puncturing device and the barrel.
3. A trocar, comprising a barrel, a puncturing device mounted to reciprocate therein, vacuum-producing apparatus connected with the trocar and receiving liquid from both the inside of the portion thereof entering the part treated and also from the outside thereof.
In testimony whereof, I have hereunto subscribed my name.
