Description
Technical field
The present invention relates to technical field of medical instruments, relate to the stapler with structure Small Intestine storage bag in art specifically, be applicable to the patient that inflammatory intestines disease, familial adenomatous polyposis etc. need to build the functional storage bag of ileum.
Background technology
Full Colon and rectum excision+ileal pouch anal anastomosis is treatment familial adenomatous polyposis and medical treatment, and invalid ulcerative colitis, total colectomy type Crohn disease etc. involves the general modus operandi of full colorectal disease.Though the mode building ileal pouch is numerous, storage bag building mode conventional clinically is at present " J " type storage bag of twofold.Add with terminal ileum constructing function storage bag the time that postoperative patient feces stops at enteral, decrease defecation frequency after operation in patients, improve the quality of life after operation in patients.Its construction method terminal ileum is folded the side to side anastomosis making terminal ileum of two line cutting stitching instruments, closes ileum intestinal tube stump again after having coincide with closer.But this storage bag built by multiple anastomat, stapler also usually faces various post-operative complication, as stored up, bag is scorching, storage bag is hemorrhage, anastomotic stricture, storage bag fistula etc.After line cutting stitching instrument completes 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, what the comparatively thorny class post-operative complication of itself and ileal pouch stored up bag stump fistula is formed with direct relation.This kind of complication is by organization formation sinus tracts 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 that very much the ileum stump processing mode to storing up bag forming at present improves.Thorough elimination storage bag ileum stump, reduces the incidence rate of storage bag fistula from the dissection aspect of storage bag forming.
Summary of the invention
Object of the present invention mainly for existing storage bag forming leave over technical problem existing for ileum stump, provide a kind of storage bag forming stapler integrating intestinal tube side to side anastomosis and end-to-side anastomosis.
