Automatic purse-string suture device

Abstract

The invention provides an automatic purse-string suture device comprising two clampers, wherein each clamper is movably provided with a nail storehouse; each nail storehouse is internally provided with a nail, a nail pushing piece and purse-string lines; each clamper comprises a vertical seat; the two nail storehouses are correspondingly arranged on the vertical seats and can move relative to respective vertical seats; the vertical seats of the two clampers are arranged in parallel; and one vertical seat can move relative to the other vertical seat under the action of a driving mechanism. The automatic purse-string suture device has the main advantage of capability of meeting the use in a smaller operation space, thereby enlarging a utilization range and providing convenience to doctors.

Description

technical field [0001] The invention relates to a purse-string suture device, in particular to an automatic purse-string suture device, which belongs to the technical field of medical devices. Background technique [0002] Surgical purse-string suture device is a medical device often used in surgical operations on intestinal and other physiological tissues. The performance of the device 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...

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 when the purse is tied, the handle holder must be opened, so that the front end of the purse is wide enough to allow tissue to enter the suture from the gap on one side without hindrance In this way, if you want to use the purse device, the surgical area must be large enough to allow the opened purse device to enter the operation area without obstacles, which limits the scope of use of the purse device, which is not conducive to giving full play to its convenient and time-saving 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 suturing devices are difficult to operate, and it is easy to cause surgical accidents
