Abstract

The invention relates to a gun type circumcision anastomat which comprises a gun type outer shell and a circumcision suture mechanism. The gun type outer shell comprises a fixed handle portion and a movable handle portion, the movable handle portion comprises a movable handle and a tension spring, one end of the movable handle is connected with the fixed handle portion through a rotating shaft, and the fixed handle portion is provided with a handheld portion matched with the movable handle. The circumcision suture mechanism is arranged on the fixed handle portion, and when the movable handle rotates in a direction close to the handheld portion, the movable handle is capable of promoting a nail pushing piece in the circumcision suture mechanism to direct push suture nails out of a nail chamber and simultaneously promoting the nail pushing piece in the circumcision suture mechanism to drive a columnar bladed incision knife to complete linear synchronous incision. The gun type circumcision anastomat has advantages that by the single handle for linear triggering, on the one hand, single-hand operation can be realized, and convenience in operation is achieved, and on the other hand, according to a linear force applying principle, accuracy in incision and anastomosing is improved, and surgical standardization, safety, quickness and convenience are realized.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pistol type circumcision stapler. Background technique [0002] With the development of medical technology and clinical verification, the cutting and suturing principle of circumcision and suture is gradually accepted by the clinical and academic circles. The main reason is that there are many defects in traditional circumcision, such as: 1. The operation time is long, About 30 minutes; 2. There is a lot of bleeding during the operation, the wound is large, and edema is prone to occur after the operation; 3. Sutures are required during the operation; 4. It is difficult to accurately control the length of the inner and outer plates of the foreskin during the operation; Edema of the frenulum is common. And utilize circumcision stapler to carry out operation, it has cutting, the advantage that sutures one step and finishes, and this method has operation fast, and bleeding is fe...
