Guiding structure of minimally invasive surgery cutting anastomat

Abstract

The invention relates to a guiding structure of a minimally invasive surgery cutting anastomat. The guiding structure comprises a guiding assembly. The guiding assembly comprises a guiding head and a receiving head, and the guiding head is arranged at the head end of the nail bin clamping plate; the guide head is correspondingly connected with the receiving head, and the receiving head extends out of the esophagus; the guide head and the nail bin clamping plate are movably connected through a first connecting piece. The guide head is a first connecting pipe matched with the head end of the nail bin clamping plate, the first end of the first connecting pipe is connected with the head end of the nail bin clamping plate, and the second end of the first connecting pipe is connected with the receiving head. The receiving head extends out of the esophagus, the guide head extends into the affected part and is correspondingly connected with the receiving head, so that the nail bin clamping plate and the guide head enter the esophagus along the receiving head, the problem that the front end of the anastomat enters the esophagus difficultly and time is consumed clinically is effectively solved, and the risk that the front end of the anastomat extends into the esophagus in a manner of being attached to the wall of a stomach tube to cause poor anastomosis or even failure is avoided; the method has the advantages of high accuracy, high docking speed and high success rate, and shows huge time advantage and brought follow-up safety advantage.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a guide structure for a minimally invasive surgery cutting stapler. Background technique [0002] Laparoscopic cutting and stapler is suitable for resection, transection and anastomosis of tissues in abdominal, gynecological, pediatric and thoracic surgery, and can also be used for resection and transection of liver parenchyma, liver blood vessels and gallbladder ducts. [0003] In the process of operating a laparoscopic cutting stapler, such as the operation of esophagojejunostomy, the current clinical practice is to place the staple cartridge splint below the tissue to be cut and extend into the jejunum, and the anvil above to extend into the esophagus. Cutting and anastomosis operation; however, due to the actual operating angle, the obstruction of other tissues in front of the cutting stapler, and the influence of the width and angle of the laparoscopic cu...

Problems solved by technology

[0003] In the process of operating a laparoscopic cutting stapler, such as the operation of esophagojejunostomy, the current clinical practice is to place the staple cartridge splint below the tissue to be cut and extend into the jejunum, and the anvil above to extend into the esophagus. Cutting and anastomosis operation; however, due to the actual operating angle, the obstruction of other tissues in front of the cutting stapler, and the influence of the width and angle of the laparoscopic cutting stapler, it is often difficult to insert the front end of the cutting stapler into the esophagus, and the cutting stapler successfully entered It takes 5-30 minutes to reach the inside of the esophagus, and often requires very complicated and fine adjustments, which is prone to various side injuries and even serious postoperative complications

At present, the commonly used operation method is to use the front end of the cutting stapler to insert into the esophagus, as close as possible to the tube wall, but even so, it often enters the esophageal dissection by mistake, resulting in poor anastomosis and postoperative complications, and the result of anastomosis failure

The operation of the whole cutting and stapler is difficult, and the damage to the jejunum is relatively large, and it is easy to cause postoperative complications such as jejunal stenosis. damage

In the prior art, in the process of minimally invasive surgery, it usually takes a long time to confirm, the accuracy is not good, it is not conducive to the operation, the operation time is prolonged, the efficiency is reduced, the difficulty and risk factor are high, and there are medical risks
