Description
Technical field
This utility model relates to a kind of axial cutting facility.
Background technology
At present, often adopt endoscope to perform the operation to human body natural's tract clinically, matching used apparatus is also more comprehensive with it.Hemorrhagely often hemostatic clamp is adopted to process with perforation is existing for organizing of human body natural's tract, larger organizing hemorrhagely is then adopted stitching thread to combine multiple hemostatic clamp with perforation to perform the operation, but for wiping out of stitching thread later stage, there is certain difficulty, do not have a kind of medical apparatus and instruments can wipe out endoscopic stitching thread fast in the market.Conventional shears can only wipe out the stitching thread outside human body, and line unnecessary in scope and human body then cannot effectively be wiped out; Some shearing apparatuses are undertaken shearing line in human body by endoscopic forceps channel, but need constantly to adjust shank by endoscope thus make shear and line is angled just can shear.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of axial cutting facility, and it can wipe out stitching thread unnecessary in the human body under endoscopic surgery well, thus improves success rate of operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of axial cutting facility, comprise outer tube assembly and push-and-pull assembly, also comprise sleeve and shear, sleeve is fixedly connected on the front end of outer tube assembly, shear is fixedly connected on the front end of push-and-pull assembly, and shear can axially movably be inserted in sleeve, shear is provided with wire guide, on shear before the end of wire guide is provided with cutting edge, the front end of sleeve is provided with the rear cutting edge coordinated with front cutting edge, and when sliding backward push-and-pull assembly and make shear move backward relative to sleeve on outer tube assembly, be through stitching thread on wire guide to be sheared under the cooperation of front cutting edge and rear cutting edge.
Further provide a kind of structure of outer tube assembly to fix sleeve well, thus be conducive to realization and wipe out sutural operation, further raising success rate of operation, described outer tube assembly comprises spring outer tube and core bar, described sleeve is fixedly connected on the front end of spring outer tube, and the rear end of spring outer tube is fixedly connected with core bar.
Further provide a kind of structure of push-and-pull assembly so that push-and-pull shear well, thus be conducive to realization and wipe out sutural operation, its success rate of operation of further raising, described push-and-pull assembly comprises drag-line, boost tube and slip ring, described shear is fixedly connected on the front end of drag-line, and drag-line is connected with one end of boost tube through described spring outer tube again, and the other end of boost tube is connected with slip ring, slip ring is sliding to be fitted on core bar.
After have employed technique scheme, axial cutting facility of the present utility model adopts the front cutting edge of shear and the rear cutting edge of sleeve to cooperatively interact to carry out axial shearing to stitching thread in the relative movement thereof of shear and sleeve, achieve stitching thread unnecessary in the human body that can wipe out well under endoscopic surgery, thus improve success rate of operation.

Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail.
As shown in Figure 1, a kind of axial cutting facility, comprise outer tube assembly and push-and-pull assembly, also comprise sleeve 2 and shear 1, sleeve 2 is fixedly connected on the front end of outer tube assembly, shear 1 is fixedly connected on the front end of push-and-pull assembly, and shear 1 can axially movably be inserted in sleeve 2, shear 1 is provided with wire guide 1-2, on shear 1 before the end of wire guide 1-2 is provided with cutting edge 1-1, the front end of sleeve 2 is provided with the rear cutting edge 2-1 coordinated with front cutting edge 1-1, and when sliding backward push-and-pull assembly and make shear 1 move backward relative to sleeve 2 on outer tube assembly, the stitching thread 8 be through on wire guide 1-1 is sheared under the cooperation of front cutting edge 1-1 and rear cutting edge 2-1.
Outer tube assembly comprises spring outer tube 3 and core bar 7, and sleeve 2 is fixedly connected on the front end of spring outer tube 3, and the rear end of spring outer tube 3 is fixedly connected with core bar 7.
Push-and-pull assembly comprises drag-line 4, boost tube 5 and slip ring 6, shear 1 is fixedly connected on the front end of drag-line 4, and drag-line 4 is connected with one end of boost tube 5 through described spring outer tube 3 again, and the other end of boost tube 5 is connected with slip ring 6, slip ring 6 is sliding to be fitted on core bar 7.
The use procedure of axial cutting facility of the present utility model is as follows:
1, the wire guide 1-2 of stitching thread 8 from shear 1 head is inserted, pass from wire guide 1-2 opposite side.
2, light pulling stitching thread 8, inserts cutting facility 1 head end in endoscopic forceps channel hole, delivers to human body domestic demand carry out suture cutting position along biopsy channel hole and stitching thread 8.
3, by pulling slip ring 6, boost tube 5, drag-line 4, shear 1 is driven to move backward, and sleeve 2 and spring outer tube 4 are because of integrally welded, and do not move, thus make shear 1 enter in sleeve 2, in relative movement, the front cutting edge 1-1 of the shear 1 and rear cutting edge 2-1 of sleeve 2 is formed and shears, thus realizes carrying out axial wiping out to stitching thread.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
