Abdominal cavity tissue section ligation device

Abstract

The invention discloses an abdominal cavity tissue section ligation device. The abdominal cavity tissue section ligation device comprises a shell, a rotating mechanism capable of puncturing tissue for the first time is arranged on the left side in the shell, a driving mechanism capable of controlling the rotating mechanism is fixedly arranged on the right side of the outer wall of the shell, a guide mechanism is rotationally arranged on the right side of the rotating mechanism, and a moving mechanism capable of performing secondary puncturing on the tissue is slidably arranged at the upper end in the shell. According to the abdominal cavity tissue section ligation device, the ligation process can be completed only by a surgeon, time and labor are saved, the operation efficiency is greatly improved, the tissue can be conveniently and rapidly ligated in a narrow body cavity, the danger that a suture needle falls into the body cavity is avoided, the operation risk is reduced, and after disinfection and sterilization, the abdominal cavity tissue section ligation device can be repeatedly used. According to the abdominal cavity tissue section ligation device, the problems of thread knot scattering, ineffective knotting, secondary damage to tissue broken sections and even secondary operation caused by the fact that a slippery knot is prone to being formed in a narrow body cavity through manual knotting are solved; and by means of the one-way buckle barb suture line ligation device, ligation is convenient, fast and effective, and the ligation success rate is high.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an abdominal tissue section ligation device. Background technique [0002] Laparoscopic minimally invasive surgery is now more and more widely used. Laparoscopic surgery is aimed at the ligation of the anatomical structure of the pipeline. Some small bile ducts and small blood vessels can be hemostasis with electrocoagulation. Some large pipelines, such as bile ducts and blood vessels, often use homelock clips. It is left in the body at one time. When performing laparotomy on patients, some large pipelines cannot be ligated by electrocoagulation, but by traditional manual ligation. The ligated pipelines are often used in a small surgical field with a traditional hand-held needle holder and threading tie. [0003] When ligating some tissues in the abdominal cavity or thoracic cavity, suture the broken end of the tissue section with a hand-held needle holder, tweezers, ...

AI Technical Summary

Problems solved by technology

[0003] When ligating some tissues in the abdominal cavity or thoracic cavity, suture the broken end of the tissue section with a hand-held needle holder, tweezers, and needle thread (for example, when performing cholecystectomy through laparotomy, the thicker hepatic ducts, bile ducts, and blood vessels on the surface of the liver cannot However, the surgical field cavity exposed by laparotomy is very narrow, especially for children or small or obese patients. The operator's hand needs to insert needles and tie knots in the narrow cavity Ligation, the hand cannot be turned, it is very difficult, and it often fails, and the operation needs to be repeated many times, which prolongs the operation time and anesthesia time, increases the difficulty of the operation, and cannot make the operation go smoothly

Even if the needle is successfully inserted, when tying the knot, the suture is often pulled out due to the pulling of the hand or because the ligation site is deep, the hand cannot fix the first knot well, resulting in a loose knot
