Annular pouch stitching instrument

Abstract

The invention provides an annular pouch stitching instrument which comprises an annular nail cabin, wherein the annular nail cabin is provided with an outer wall and an inner wall; a plurality of nail holes are arranged and perforated from the outer wall to the inner wall; a nail pushing piece and a nail are arranged in each nail hole; pouch lines are arranged between the nail pins of the nails; and the nail pushing pieces can move relative to the annular nail cabin along the direction from the outer wall to the inner wall and can push the nails out of the annular nail cabin to penetrate into tissues. The annular pouch stitching instrument of the invention has small and exquisite volume, can be used as an accessory of other surgical instruments to be packed and sold together, saves the material cost and can reduce the economic burden of patients; and the automatic pouch stitching instrument can be applied to smaller surgical space, thereby enlarging the application range and providing convenience for doctors.

Description

technical field [0001] The invention relates to a purse-string suturing device, in particular to an automatic purse-string suturing device, which belongs to the technical field of medical instruments. Background technique [0002] Surgical purse-string suturing device is a medical device often used in surgical operations on intestinal and other physiological tissues. 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 for suturing, purse-string sutures must be performed on the stump of the organ, so that it can be firmly ligated after the central rod is inserted, and then the stapler can be implemented. There are two methods of performing purse-string suture surgery: one is manual suture, which is not only time-consuming and labor-intensive, but also the depth of the needle is different, and the needle pitch is inconsistent; the other is to use purse-string su...

AI Technical Summary

Problems solved by technology

It can be seen that the process of making a purse is very simple and time-saving, but because when the purse is tied, the upper and lower clamps must be opened, so that the front end of the purse is wide enough to make the tissue unobstructed from the gap on one side Enter the suture area, so that if you want to use the purse device, the operation area must be large enough to allow the opened purse device to enter the operation area without hindrance, which limits the scope of use of the purse device and is not conducive to giving full play to its convenient and time-saving functions. effect

When purse-string suturing is performed on some special surgical sites, such as the high esophagus and low rectum, because the operation space in the above two cases is small, ordinary purse-string sutures are difficult to operate, and it is easy to cause surgical accidents
