Description
Technical field
The present invention relates to a kind of laparoscopic surgical instruments, particularly a kind of air shuttle valve for peritoneoscope perforator.
Background technology
Laparoscopic surgery is exactly the operation utilizing peritoneoscope and related equipment thereof to carry out: use cold light source to provide illumination, lens of laparoscope (diameter is 3 ~ 10mm) is inserted intraperitoneal, the image using digital camera technology that lens of laparoscope is photographed conducts to rear class signal processing system by optical fibers, and is presented in real time in dedicated monitor.Then doctor is by the image of patient organ's different angles shown on monitor screen, carries out analysis and judges, and use special peritoneoscope mis instruments to perform the operation to the state of an illness of patient.
In laparoscopic surgery, peritoneoscope perforator is absolutely necessary operating theater instruments, the following shortcoming of peritoneoscope perforator ubiquity domestic at present: the sealing effectiveness of utensil is bad, during mis instruments turnover, retardance is larger, when mis instruments passes in and out repeatedly, easy damaged sealing member or the phenomenon that former sealing is leaked air, there is hidden danger in Clinical practice, often causes operation smooth and easyly not carry out, affect surgical result, even jeopardize patient vitals.
Summary of the invention
The shortcomings such as the sealing effectiveness that the object of the invention is to solve present stage peritoneoscope perforator is bad, the gas leakage of sealing member easy damaged, and a kind of air shuttle valve for peritoneoscope perforator proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of air shuttle valve for peritoneoscope perforator, described peritoneoscope perforator comprises thimble assembly, thimble assembly is connected black box, described thimble assembly comprises sleeve pipe, a pedestal is connected in one end of sleeve pipe, be connected an air shuttle valve in pedestal, it is characterized in that: described air shuttle valve is barrel-like structure, it comprises staving, one end of staving is provided with drum head, the other end is provided with opening, be provided with an extension plate in the outside of described drum head, be provided with in-line seam in the central authorities of drum head, in-line seam runs through described drum head and extension plate.
On the basis of technique scheme, following further technical scheme can be had:
Described extension plate is set square structure, and it is arranged on described drum head, is arranged on the axis of described staving with the summit of the extension plate be arranged on corresponding to drum head top.
The lateral surface of described drum head is provided with two outer inclined-planes, and two outer inclined-planes are arranged on the both sides of described extension plate, and are symmetrical arranged relative to extension plate, and each described outer inclined-plane is obliquely installed to described opening by extension plate.
Be provided with two interior inclined-planes at the medial surface of described drum head, two interior inclined-planes are arranged on the both sides of described in-line seam, and are symmetrical arranged relative to in-line seam, and each described interior inclined-plane is obliquely installed to described opening by in-line seam.
The staving of described open outer side is provided with flange.
The invention has the advantages that: compared with prior art peritoneoscope perforator adopts the air shuttle valve of the design, it is made to keep excellent sealing gas barrier properties, simultaneously can when there being instrumentation to pass in and out, be convenient to again the flexible swing of operating theater instruments, reduce apparatus turnover retardance sense, effectively ensure that the safety of Clinical practice, effectiveness.

Detailed description of the invention
In order to make the present invention clearly understand, describe in detail this device below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 3, a kind of air shuttle valve for peritoneoscope perforator provided by the invention, described peritoneoscope perforator comprises thimble assembly, thimble assembly is connected black box, and described thimble assembly comprises sleeve pipe 3, is provided with a puncturing lever 4 in sleeve pipe 3, a pedestal 2 is connected in one end of sleeve pipe 3, pedestal 2 is socketed on puncturing lever 4, and be connected an air shuttle valve 1 in pedestal 2, and air shuttle valve 1 coordinates with puncturing lever 4.Puncture vertebra head 10 is connected in puncturing lever 4 front end, puncturing lever handle cover is connected in the rear end of puncturing lever 4, described black box comprises cooperatively interacting and is connected to retainer ring 8 and lower retainer ring 7, be connected four diaphragm seal diaphragms 6 and four enhanced film sheets 5 are stacked between upper retainer ring 8 and lower retainer ring 7, four diaphragm seal diaphragms 6 stack and coordinate formation cone, four enhanced film sheets 5 also coordinate formation cone, and four enhanced film sheets 5 are arranged in the cone of four diaphragm seal diaphragms 6 cooperation formation, upper retainer ring 8 also connects a sealing ring by stationary gland 9.
Shown in composition graphs 1 and Fig. 2, the barrel-like structure that described air shuttle valve 1 is made for rubber, it comprises staving 1a, and one end of staving 1a is provided with drum head 1b, the other end is provided with opening 1c, and the staving 1a outside opening 1c is provided with flange 1f.Be provided with an extension plate 1d in the outside of described drum head 1b, described extension plate 1d is isoceles triangle plate structure, and its base is arranged on described drum head 1b, and its summit is arranged on the axis of described staving 1a.
Be provided with in-line seam 1e in the central authorities of drum head 1b, in-line seam 1e runs through described drum head 1b and extension plate 1d.The lateral surface of described drum head 1b is provided with two outer inclined-planes, and two outer inclined-planes are arranged on the both sides of described extension plate 1d, and are symmetrical arranged relative to extension plate 1d, and each described outer inclined-plane is obliquely installed to described opening 1c by extension plate 1d.Be provided with two interior inclined-planes at the medial surface of described drum head 1b, two interior inclined-planes are arranged on the both sides of described in-line seam 1e, and are symmetrical arranged relative to in-line seam 1e, and each described interior inclined-plane is obliquely installed to described opening 1c by in-line seam 1e.
