Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an abdominal wall suturing device. Background Art

[0002] During laparoscopic surgery, operations and suturing need to be performed through the abdominal wall. Traditional abdominal wall suturing uses suture needles, sutures, tissue forceps or tweezers. Choose the appropriate suture and hold the suture needle to suture the skin. During the suturing process, manually control the distance between the suture needle and the two sides of the abdominal incision, insert the suture needle into the skin, pass through one side of the incision, and then pass out from the other side of the abdominal incision. Then tie the sutures that pass through both sides of the incision. This method of suturing is troublesome and requires a certain amount of suturing experience, so it is not applicable.

[0003] The existing abdominal wall suturing device is provided with a puncture device and a suturing device. The puncture device and the suturing device cooperate with each other. First, the puncture device is inserted into the abdominal incision, and the suture is passed through the socket at the bottom of the puncture device. At this time, the suturing device pierces the skin on one side of the incision and punctures the abdominal skin. Then, the suturing device is pulled out from the socket on one side of the bottom of the puncture device and then inserted from the socket on the other side of the bottom to pierce the skin on the other side of the incision. The thread left in the abdomen is pulled out by the clamp at the bottom of the suturing device. After use, the puncture device is directly pulled out and the suture is tied.

[0004] However, although the conventional abdominal wall stapler is inserted through a socket on one side of the bottom of the puncture device, it is difficult to control the suturing distance due to the large socket. In addition, when the conventional abdominal stapler is pulled out, the sutures pass through the socket at both ends, and direct pulling out easily leads to knotting and damage to the abdominal muscle tissue. In addition, when cleaning the puncture device, the long tube opening at the bottom of the puncture device is inconvenient to clean.

[0005] Therefore, it is necessary to provide a new abdominal wall stapler to solve the above technical problems. Utility Model Content
