Minimally Invasive Surgery Rapid Deep Knotter

Abstract

The invention relates to a rapid deep-portion knotting device for minimally invasive surgery. The rapid deep-portion knotting device comprises a guide suture ring and a knotting gun. The rapid deep-portion knotting device is characterized in that a guide hole is formed in the portion, close to an outlet, of a gun head, a containing chamber is formed in the gun head, the position, close to the outlet, of the containing chamber is a knotting station, a plurality of knotting buckles are arranged in the containing chamber, the knotting station can contain only one knotting buckle, a through hole is formed in each knotting buckle, one opening of each through hole is located on the end face, facing the outlet, of the corresponding knotting buckle, when the corresponding knotting buckle is located at the knotting station, the other opening of the corresponding through hole is right opposite to the guide hole, and after a suture to be knotted is fixed to the guide suture ring, the guide suture ring passes through the outlet with the suture to penetrate through the through hole of the knotting buckle located on the knotting station and then penetrates out of the guide hole. The rapid deep-portion knotting device overcomes the defect that when a part of existing products are adopted, two people must cooperate to complete knotting, and rapid knotting is also achieved through continuous discharging; meanwhile, operation is simplified, and the learning curve of a user is shortened.

Description

technical field [0001] The invention relates to a knotter used in surgical operations, especially minimally invasive operations, which enables a surgeon to complete knotting quickly, continuously and reliably by one person in a limited operating space. Background technique [0002] With the advancement of surgical technology, minimally invasive surgery has become a hot spot in the development of various surgical disciplines. Minimally invasive surgery has the characteristics of small incision and fast recovery, but at the same time, it puts forward higher requirements for the technique of the surgeon. The suturing and knotting operations involved in minimally invasive surgery usually require the surgeon to complete the knotting with the help of an assistant with the help of a special extended suture pulling instrument, or use the manipulator of the surgical robot to tie the knot, the above two The method, especially the latter, has a certain learning curve.

Problems solved by technology

The suturing and knotting operations involved in minimally invasive surgery usually require the surgeon to complete the knotting with the help of an assistant with the help of a special extended suture pulling instrument, or use the manipulator of the surgical robot to tie the knot, the above two The method, especially the latter, has a certain learning curve. Beginners tend to tie knots slowly, with poor quality, and even knots that cannot be completed at one time and require repeated operations.

These factors greatly prolong the operation time, affect the safety of the operation, and become an important factor restricting the development of minimally invasive surgery.
