Abstract

The invention relates to the field of medical apparatuses, in particular to an endoscope puncture hole simple suturing device for a surgery. The endoscope puncture hole simple suturing device comprises a puncture needle and an abdominal wall support device, a clamping port for clamping a suture is formed in the end of the puncture needle, and the abdominal wall support device comprises a supporting rod and a cannula sleeving the supporting rod; the supporting rod is provided with puncture holes matched with the puncture needle, a supporting mechanism is arranged at the bottom of the cannula and made from flexible materials, the cannula slides along the supporting rod, and the supporting mechanism is deformed in the radial direction of the supporting rod to form a supporting part used for supporting the abdominal wall; the supporting part is provided with a suture clamping groove used for clamping the suture, the puncture holes are communicated with the suture clamping groove, a sutureend of the suture is reserved outside the abdominal wall in advance, the length of the suture to be pulled to penetrate through the abdominal wall is reduced, and damage of a peritoneum layer cannot be caused; by adjusting the position of the cannula, the supporting range of the supporting mechanism is changed, and the application range of the suturing device is expanded.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a simple suturing device for laparoscopic poking holes for surgical operations. Background technique [0002] Surgical abdominal surgery mainly includes laparoscopic surgery and laparotomy. In laparoscopic surgery, the doctor makes a few small holes around the patient's surgical site, cooperates with the endoscope for inspection and treatment, and visually observes the internal situation of the patient in front of the computer screen. Surgical operation. Laparotomy is a conventional open operation. An incision is made on the patient's hand and the abdominal cavity is opened under direct vision. [0003] Chinese invention patent application CN105748121A discloses a laparoscopic poking suture device. The operating core is protected by an outer sleeve and inserted into the laparoscopic poking hole. The peritoneum positioning device quickly locates the peritoneum to be sutured, a...
