Abstract
A cutting stitcher for storage bag forming comprises an elongated main body (1). One end of the elongated main body (1) is a working end while the other end of the same is an operating end, a closed ring is arranged at the working end, a rear-end stitching rod (3) connected with a rotating shaft of the elongated main body (1) is arranged at the operating end on the upper portion of the elongated main body (1), a head-end stitching component is arranged on the lower portion of the elongated main body (1), and a nail pushing cutting component and a nail feeding component are arranged in the elongated main body (1). The cutting stitcher has the advantages that a nail pressing plate is pre-disposed above stapler nails, so that curvilinear motion of a nail pushing device during pushing is enabled to be possible; difference in stitching force on tissue by a near end and a remote end due to pure near-end stitching of a conventional linear cutting stitcher is eliminated; nail leaking is avoided at the final stage of nail forming, and tail-end nailing quality is guaranteed; two cutting stitching lines which are commonly used by a cutting stitcher during storage bag forming are reduced to be one cutting stitching line, storage-bag stub ends are eliminated, and storage-bag complication is expected to be reduced; number of the cutting stitchers used during operation is reduced, and medical consumable cost is saved.
Description
Technical field
The present invention relates to technical field of medical instruments, relate to specifically store up by structure Small Intestine in art the stapler of bag, be applicable to inflammatory intestines disease, familial adenomatous polyposis etc. and need to build the functional patient who stores up bag of ileum.
Background technology
Full knot rectum resection+ileal pouch anal anastomosis is the general modus operandi that treatment familial adenomatous polyposis and invalid ulcerative colitis, the total colectomy type Crohn disease etc. of medical treatment involve full colorectal disease.Though it is numerous to build the mode of ileal pouch, " J " type storage bag that conventional storage bag building mode is twofold clinically at present.Increase the time that postoperative patient feces stops at enteral with terminal ileum constructing function storage bag, reduced defecation frequency after operation in patients, improved the quality of life after operation in patients.Its construction method is by the folding terminal ileum side to side anastomosis that makes terminal ileum of two line cutting stitching instruments, after having coincide, closes ileum intestinal tube stump again with closer.But this storage bag being built by multiple anastomat, stapler also usually faces various post-operative complication, as scorching in storage bag, storage bag is hemorrhage, anastomotic stricture, storage bag fistula etc.Line cutting stitching instrument completes after the side to side anastomosis of intestinal tube, the ileum broken ends of fractured bone of closing with closer.Exactly because there be the residual of this broken ends of fractured bone, the comparatively thorny class post-operative complication of itself and ileal pouch stores up the direct relation that is formed with of bag stump fistula.This kind of complication forms sinus tract by tissues such as ileum stump and pelvic cavity, bladder, vagina, skins, and Chang Jingjiu does not more make patient's body and mind bear great injury, and usually makes clinicist face a severe test to the treatment of this type of complication.
Therefore, be necessary very much the ileum stump processing mode of current storage bag forming to improve.Thoroughly eliminate storage bag ileum stump, reduce the incidence rate of storage bag fistula from the dissection aspect of storage bag forming.
Summary of the invention
Object of the present invention is mainly to leave over the existing technical problem of ileum stump for existing storage bag forming, and a kind of storage bag forming stapler that integrates intestinal tube side to side anastomosis and end-to-side anastomosis is provided.
It is that ileal pouch that former need three just can be completed apparatus builds and is reduced to a stapler and can realizes that the present invention also has an object; The storage bag forming that a kind of effect is sure, cost is low stapler is provided.
A kind of storage bag forming stapler, comprises rectangular flute profile main body 1, and rectangular flute profile main body 1 one end is working end, and the other end is operating side, and described working end is close ring; Rectangular flute profile main body 1 upper operating end is provided with the rear end pressing bar 3 being connected with rectangular flute profile main body 1 rotating shaft, and rectangular flute profile main body 1 bottom is provided with head end pressing assembly, establishes ejector pin cutting assembly and send screw assembly in rectangular flute profile main body 1;
