Pocket stitching device with knife

Abstract

The invention provides a pocket stitching device with a knife, comprising an upper shell, a lower shell and a nail bin assembly. The upper shell and the lower shell are oppositely arranged, and the nail bin assembly is arranged inside the shell. The nail bin assembly comprises a nail bin, a pin-ejecting piece, a pocket thread and a nail, wherein the pin-ejecting piece, the pocket thread and the nail are arranged in the nail bin; a lower nail bin arranged inside the lower shell is provided with a nail bin groove; the lower shell is provided with a cutting knife; the cutting knife passes through the nail bin groove with a knife blade opposite to the upper shell; and the cutting knife is used for cutting off tissues when the pocket stitching device triggers. The invention has the advantages that the tissues are conveniently cut in a special operation position, and the pocket stitching and the tissue cutting are combined into one step.

Description

technical field [0001] The invention relates to a purse suture, in particular to a purse suture with a knife, and belongs to the field of medical instruments. Background technique [0002] Surgical purse-string stapler is a medical device that is often used in surgical operations on physiological tissues such as the intestine. The performance of the instrument directly affects the operation process and plays a very important role in the operation effect. In the prior art, when using a stapler to perform a suture operation, purse-string sutures must be performed on the stump of the organ, so that the central rod can be firmly ligated, and then the stapler operation can be performed. There are two ways to perform purse-string suture: one is manual suture, which is not only time-consuming and labor-intensive, but also the needles are inserted deep and shallow, and the needle distance is inconsistent; The disadvantage of purse-string suture through the organized jaws is that a ...

AI Technical Summary

Problems solved by technology

Since the purse-string device is generally used for purse-string suturing of some tubular tissue stumps, there is no need to dissect the tissue. However, when purse-string suturing is performed on some special surgical sites, such as the high position of the esophagus and the low position of the rectum, the purse string is often used first. Then cut off the tissue to produce a stump. At this time, another scalpel is needed to cut the tissue, which makes the operation steps cumbersome, and because the operation space in the above two cases is small, it is difficult for an ordinary scalpel to penetrate into the tissue. , prone to surgical accidents
