Stepping type cutting pouch stitching instrument

Abstract

The invention provides a stepping type cutting pouch stitching instrument comprising two handle clip holders which are mutually articulated. The tail parts of the handle clip holders are holding parts, and the front ends of the handle clip holders are stitching parts; the stitching parts are internally provided with nail caskets and nail pushing sheets, wherein the nail caskets are internally provided with nail rows, and pouch threads are arranged between the nail rows and nail pins; one handle clip holder is also provided with a cutting knife, and the other handle clip holder is correspondingly provided with a knife anvil; when the holding parts are tightly held, nails positioned on the nail rows can be sequentially pushed out of the nail caskets by the nail pushing sheets, and the cutting knife and the knife anvil are interact to divide structures positioned between the stitching parts of the handle clip holders. The invention can carry out pouch stitching in corresponding length according to the lengths of the structure and divide the structures when carrying out the pouch stitching, therefore the stepping type cutting pouch stitching instrument is more convenient to use; and besides, the stepping type cutting pouch stitching instrument can be adapted to the structures with different diameters.

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 field of medical devices. 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 suture forceps t...

Problems solved by technology

It can be seen that the process of making a purse is very simple and time-saving, but because the head of this purse suturing device has a fixed size and length, it cannot adapt to some operations in special positions, such as high esophageal surgery; at the same time, it cannot adapt to differences in human tissues properties, such as tissue wall thickness
