Nail anvil assembly used under complete laparoscope, guiding device and surgical instrument

Abstract

The invention discloses a nail anvil assembly used under a complete laparoscope, a guiding device and a surgical instrument, and relates to the field of medical instruments used under the laparoscope, the nail anvil assembly comprises a nail anvil umbrella, a nail anvil rod and an umbrella body contraction piece, and the umbrella body contraction piece can be controlled through external force so that the nail anvil umbrella can be unfolded or folded; under the condition that the nail anvil umbrella is folded, the radial size of the nail anvil umbrella is the same as that of the nail anvil rod, the nail anvil umbrella can effectively penetrate into the abdominal cavity of a patient through a laparoscope trocar and be placed into the gastrointestinal tract anastomotic stoma stump, so that a 3-5 cm incision does not need to be additionally formed in the position, close to the upper anastomotic stoma stump, of the patient, and the problem that more iatrogenic injuries are caused to the patient is effectively avoided; a fixing needle is arranged at the lower end of the nail anvil umbrella, after the nail anvil umbrella is placed into the anastomotic stoma stump end, the whole nail anvil assembly is rotated, the fixing needle can be inserted into the inner wall of the gastrointestinal tract anastomotic stoma stump end section, fixing of the whole nail anvil assembly is achieved, the process is rapid and accurate, and purse-string suture is not needed.

Description

technical field [0001] The invention relates to the field of medical instruments for laparoscopy, in particular to an anvil assembly, a guiding device and a surgical instrument for complete laparoscopy. Background technique [0002] Laparoscopic gastrointestinal resection is currently one of the mainstream surgical intervention methods for gastrointestinal tumors. After partial resection of the gastrointestinal tract, the remaining gastrointestinal tract needs to be re-sutured to ensure the continuity of the anatomical structure of the human gastrointestinal tract. With the continuous development of surgical medical equipment, the method of gastrointestinal anastomosis has been improved from the original traditional manual anastomosis to cutting stapler anastomosis. The anvil is an important part of the cutting anastomat. The operator needs to place the upper anvil into the anastomosis and fix it. The lower cutting stapler is combined with the anvil rod to activate the cutti...

Problems solved by technology

This process is complicated to operate under laparoscopic conditions, and the failure rate is high, which increases the difficulty of surgery, operation time and operation risk, which is an important reason for the prolongation of operation time, and also hinders the promotion of complete laparoscopic surgery.
