A cutting and sewing device for forming storage bags

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 [0001] The invention relates to the technical field of medical devices, in particular to a cutting and suturing device for constructing a functional pouch of the small intestine during an operation, which is suitable for patients who need to construct a functional pouch of the ileum, such as inflammatory bowel disease and familial adenomatous polyposis. Background technique [0002] Total colorectal resection + ileal pouch-anal anastomosis is a general surgical method for the treatment of familial adenomatous polyposis, ulcerative colitis, and pan-colonic Crohn's disease, which involve the entire colorectum. Although there are many ways to construct an ileal pouch, the commonly used pouch construction method in clinical practice is a double-folded "J" pouch. Using the terminal ileum to construct a functional storage bag can increase the time for feces to stay in the intestine after surgery, reduce the number of defecation after surgery, and improve the qualit...

Problems solved by technology

This kind of complication is composed of the ileum stump and the pelvic cavity, bladder, vagina, skin and other tissues to form a sinus tract, which often does not heal for a long time, causing great physical and mental damage to the patient, and the treatment of such complications often makes clinicians face severe challenges
