Abstract
The invention relates to a linear anastomat with a cutting device, comprising an instrument body (7), a nail-abutting seat (1) and a pushing plate (6). The pushing plate (6) is mounted at the front part of the instrument body (7); the front part of the pushing plate (6) is also provided with a pushing slice (4) and a nail chamber (2) which is mounted relative to the nail-abutting seat (1); and an anastomat nail is mounted on the end surface of the pushing slice (4). The linear anastomat with the cutting device also comprises a cutting knife (3) and a knife holder (5), wherein the cutting knife (3) is fixed on the knife holder (5) which is mounted between the pushing slice (4) and the pushing plate (6); and the front end of the cutting knife (3) penetrates through a groove between the nail chamber (2) and the pushing slice (4). The invention has simple structure and convenient operation, and the aims of simultaneously sewing and cutting can be achieved by only using a single anastomat.
Description
Technical field
The present invention relates to operation and use medical instruments field, specifically, relate 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 objective of the invention 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 invention 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
The present invention is further detailed explanation below in conjunction with drawings and Examples.
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 invention 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.
