Single-hole laparoscopic spleen retractor

Abstract

The invention provides a single-hole laparoscopic spleen retractor. The retractor is characterized by comprising a push-pull assembly, an outer sleeve, a sleeving assembly and a pressurizing assembly;the push-pull assembly can cause relative displacement between the outer sleeve and the sleeving assembly for storing or exposing the sleeving assembly; the sleeving assembly comprises inflatable protective sleeves and sleeving pieces disposed in the protective sleeves, the sleeving pieces are made of memory materials, and the protective sleeves are communicated with the pressurizing assembly. The single-hole laparoscopic spleen retractor can sleeve the spleen and vigorously pull the spleen without damaging the spleen to fully expose ligaments around the spleen, a surgeon can handle blood vessels connected to the spleen conveniently, and implementation of an operation is facilitated.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to a single-hole laparoscopic spleen retractor. Background technique [0002] Laparoscopic splenectomy was first reported in 1992, and since then has been carried out in various countries around the world. In 2008, the European Society of Endoscopic Surgery pointed out that laparoscopic splenectomy has become the standard operation for most benign and malignant diseases of the spleen, and can almost replace open splenectomy. Although this guideline still lists splenomegaly and portal hypertension as contraindications, with the development of laparoscopic technology and various instruments, there have been a large number of reports on laparoscopic treatment of portal hypertension at home and abroad. Although this method is risky and technically difficult, as long as the surgical indications are strictly grasped, the preoperative preparation is adequate, the operation is c...

AI Technical Summary

Problems solved by technology

However, due to the smooth surface of the spleen, sometimes it is difficult to lift and the front end of the rod is easy to pierce the spleen, causing bleeding and affecting the operation process

Especially for patients with portal hypertension, the surrounding adhesions are severe, and the spleen is large, so it is difficult to operate simply by pulling out t...
