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 the width of the tissue

Abstract

The invention discloses a chain purse-string suture instrument, comprising staple cartridge components which are set oppositely. The staple cartridge components comprise a staple cartridge, and pushing staple plates and staples which are arranged in the staple cartridge, wherein a piece of purse string passes through ends of the staples. The chain purse-string suture instrument comprises two staple cartridge rows connected by a plurality of staple cartridge components, and a pushing block which can be driven forward. In the forward process, the pushing block can successively drive the pushing staple plates of the staple cartridge components and push the staples out of the staple cartridge. The invention has the advantages that the chain purse-string suture instrument can carry out a purse-string suture with a corresponding length according to the length of tissues; and the instrument can adapt to different tissues with different diameters.

Description

technical field [0001] The invention relates to a purse-string suturing device, in particular to a chain-type automatic purse-string suturing device, which belongs to the field of medical equipment. 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 sutu...
