Blood vessel ligation device for minimally invasive surgery

Abstract

The invention provides a bottom-holding type blood vessel and tissue ligation device mainly applied to the minimally invasive endoscopic surgery. The blood vessel and tissue ligation device mainly comprises a ligation device and a ligation strip, wherein the ligation strip is similar to a binding tape used in daily life, a notch is formed in the center of a clamping groove at the tai lend, and the head end can be clamped in by the notch; the ligation device comprises two layers of structures including an inner layer and an outer layer, the outer layer is a sleeve shell, and the inner layer is a main body structure; the sleeve shell is an accessory device and mainly plays protecting and smoothening roles; the inner main body structure of the ligation device mainly comprises two vertical pulleys, a three-cavity operating rod, a handle, spanners, a safety device, micro scissors, a q-like-shaped sliding rail device, an internal connecting rod, springs and the like. A fixing shaft for the two vertical pulleys, the three-cavity operating rod, the handle, and sliding rails of the q-like-shaped sliding rail device of the main body structure are of an integrated structure; round-ring-like structures of the inner layer and the outer layer of the sliding rail device are connected through embedded rails, and the 1 / 4-round-ring-like structure at the inner layer can form a closed round ring through the safety device at the tail end in a sliding manner, so that the purpose of ligating the blood vessel is achieved. The blood vessel and tissue ligation device can be universally used for various endoscope surgeries, including ligating the blood vessels, ductus cysticus and other lumen tissues. The invention aims at providing the convenient, safe and effective blood vessel ligation device for the minimally invasive surgery for surgeons.

Description

technical field [0001] The invention mainly relates to the field of medical equipment, in particular to a minimally invasive surgery blood vessel ligation device. Background technique [0002] With the advancement of medical technology and people's ideas, surgical operations tend to be minimally invasive, and laparoscopy is increasingly used in surgery; laparoscopy, thoracoscopy, arthroscopy, cystoscopy, hysteroscopy and other laparoscopy Surgery is bringing benefits to more and more patients. However, vascular ligation under various laparoscopic surgeries has always been a difficult problem for clinicians. Traditional laparoscopic ligation of blood vessels uses titanium clips or Hem-o-lok clips, but due to the limited vision of doctors and surgical tools, they can only be clamped from top to bottom. During the operation, clinicians need to repeatedly confirm whether the blood vessels are clamped firmly , Clamping too deep will damage the deep tissue, and clamping too shall...

Traditional laparoscopic ligation of blood vessels uses titanium clips or Hem-o-lok clips, but due to the limited vision of doctors and surgical tools, they can only be clamped from top to bottom. During the operation, clinicians need to repeatedly confirm whether the blood vessels are clamped firmly , Clamping too deep will damage the deep tissue, and clamping too shallow will not be able to completely clamp blood vessels, which will bring troubles to clinical operations
