Description

stapler

The present invention relates to a suturing device, especially a suturing device for tendon suturing.

For patients with tendon rupture, tendon suture work is usually performed to re-suture the ruptured tendon to restore function. Usually, a small incision is made in the affected part by means of minimally invasive surgery to insert the stapler, and the puncture needle is inserted into the affected area. The suture is brought into the tendon at the affected site, and the threading is completed by repeatedly pulling the suture, thereby suturing the tendon. However, when the worker inserts the stapler into the affected tissue and hooks out the suture, the stapler is tied in the tissue and cannot be seen visually. It is necessary to judge the position of the suture in the tissue by experience, and it is impossible to accurately know whether the suture has been removed. Hooking the suture may easily cause various problems such as unsmooth operation and prolonged operation time.

In view of this, the conventional tendon suture work indeed still needs to be improved.

In order to solve the above problems, the purpose of the present invention is to provide a suturing device, which can improve the smoothness of tendon suturing.
