Abstract

The utility model relates to a linear type anastomat provided with a cutting device, comprising a machine body (7), a nail resisting seat (1) and a push plate (6), wherein the push plate (6) is installed in front of the machine body (7); the front of the push plate (6) is also provided with a push piece (4) and a nail bin (2); the nail resisting seat (1) and the nail bin (2) are arranged in an opposite way; and the end surface of the push piece (4) is provided with an anastomotic nail. The linear type anastomat further comprises a cutter (3) and a cutter seat (5), wherein the cutter (3) is fixed on the cutter seat (5) which is arranged between the push piece (4) and the push plate (6); and the front end of the cutter (3) passes through a groove arranged between the nail bin (2) and the push piece (4). The linear type anastomat has simple structure and convenient operation, and the aims of sewing and cutting can be simultaneously realized in the operation only by one anastomat.

Description

The linear anastomat of band cutter sweep

Technical field

This utility model relates to operation and uses medical instruments field, specifically, relates to a kind of linear anastomat of band cutter sweep of the usefulness of performing the operation, stitching that can undergo surgery simultaneously and cutting.

Background technology

Linear anastomat claims the digestive tract closer again, is a kind of apparatus that the seams nail of a plurality of arrangements that intermesh can be in line organizationally and hammer into, and also is one of the apparatus of instead of manual straight line stitching that is widely used.Be mainly used in and sew up the stump of closing stomach, duodenum, small intestinal, colon, for the holostrome eversion type is sewed up.

Be difficult to appear under the situation of art open country, surgeon usually faces many challenges, as: 1. apparatus is difficult to enter the lower position of pelvic cavity; 2. apparatus can block the operation visual field; 3. to prepare multiple apparatus sometimes and adapt to different pelvic cavity structures; 4. in the low level pelvic cavity, the operation that does not have the space to cut and sew up; 5. how to reduce infection chance, reduce the wound of tissue etc.

There is a shortcoming in traditional linear anastomat at present, has only the stitching function that is:, no cutting function, operation inconvenience.In order to separate unnecessary tissue, need manually excise, but doctor's operation skill has nothing in common with each other with blade, the cutting maneuver is inconsistent, carrying out separation of sharp property or electric knife can damaged tissue when separating.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of only use single anastomat just can the purpose that realization is sewed up simultaneously and cut when performing the operation linear anastomat.

The technical scheme that realizes above-mentioned purpose is: a kind of linear anastomat with cutter sweep, comprise instrument body, nail supporting base and push pedal, push pedal is installed in the instrument body front portion, in the push pedal front portion push jack and nail bin are installed also, support that needle stand is relative with nail bin to be installed, on the push jack end face anastomosis staple is installed, also comprise cutter and tool rest, cutter are fixed on the tool rest, and tool rest is installed between push jack and the push pedal, and the cutter front end passes nail bin and the intermediary groove of push jack.

After adopting technique scheme, owing to increased cutter sweep on this linear anastomat, thus avoided the common anastomosed by instrument of using earlier, the complication that causes when the loaded down with trivial details and such execution stitching of the artificial excision of reuse scalpel and cutting operation.Push pedal of the present utility model promotes the tool rest bottom surface, the tool rest end face promotes the push jack bottom surface, anastomosis staple on the push jack end face is carried out the action of suture tissue, the cutter that are fixed on the tool rest are carried out the action that cuts and organizes, in once-through operation, sew up simultaneously like this and cut and organize, promptly realize the action of stitching and cutting, use this apparatus to reduce the instrument of operation usefulness on the one hand, also simplify the operation technique flow process on the other hand, and then pollute in the maximum possible minimizing art, increased the visuality of art open country, clinical manipulation is simple and practical, and is more welcome than traditional instruments.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail.

Shown in Fig. 1～7, a kind of linear anastomat with cutter sweep, comprise instrument body 7, nail supporting base 1 and push pedal 6, push pedal 6 is installed in instrument body 7 front portions, in push pedal 6 front portions push jack 4 and nail bin 2 is installed also, support needle stand 1 and nail bin 2 relative installations, on push jack 4 end faces anastomosis staple is installed, also comprises cutter 3 and tool rest 5, cutter 3 are fixed on the tool rest 5, tool rest 5 is installed between push jack 4 and the push pedal 6, and cutter 3 front ends pass nail bin 2 and push jack 4 intermediary grooves.

Operation principle of the present utility model is as follows:

As Fig. 1 and shown in Figure 7, the push pedal 6 of anastomat promotes tool rest 5 bottom surfaces, tool rest 5 end faces promote push jack 4 bottom surfaces, anastomosis staple on push jack 4 end faces is carried out the action of suture tissue, the cutter 3 that are fixed on the tool rest 5 are carried out the action that cuts and organizes, in once-through operation, sew up simultaneously like this and cut and organize, promptly realize the action of sewing up and cutting.

Claims

1. linear anastomat with cutter sweep, comprise instrument body (7), nail supporting base (1) and push pedal (6), push pedal (6) is installed in instrument body (7) front portion, in push pedal (6) front portion push jack (4) and nail bin (2) are installed also, support the relative installation of needle stand (1) with nail bin (2), on push jack (4) end face anastomosis staple is installed, it is characterized in that: also comprise cutter (3) and tool rest (5), cutter (3) are fixed on the tool rest (5), tool rest (5) is installed between push jack (4) and the push pedal (6), and cutter (3) front end passes nail bin (2) and the intermediary groove of push jack (4).
