Suture silk device for easy ligature for operation

Abstract

Operational suturing device has suture with single fiber core inside a cylindrical screen and the suture is inserted into a support pipe with guide hole. In front of the support pipe, the suture constitutes one ring and one knots; and except the part in the A section between the ring and the knot has the core material is coated with hardening agent painted on the surface. The other end of the suture is fixed at the end of the support pipe and there are handle, air passage hole and cutting slot at this end. The guide pipe outside the support pipe has sharp cutting blade in the tip.

Description

technical field [0001] The invention relates to a surgical sealing wire device that is easy to ligate, which belongs to a device used for sealing wounds in surgical medical instruments, and is especially used in laparoscopic, thoracoscopy and discoscopic surgery, where the sealing wire is used for ligation. Surgical site and cut off the remaining sealing wire. Background technique [0002] As far as the current situation of this type of surgery is concerned, under the field of view of the endoscope, the work of tying the sealing wire with the endoscopic surgical instrument can only be done by a highly skilled doctor, so the endoscopic surgery is limited, so the use of The method of making a ferrule in advance outside the body, and then ligating the surgical site of the blood vessel or other organs inside the abdominal cavity, but because the sealing wire is too soft and cannot maintain a certain shape of the ferrule, it is difficult to set it. Live at the surgical site. In...

Problems solved by technology

[0002] As far as the current situation of this type of operation is concerned, under the view of the endoscope, the work of binding the sealing wire with the endoscopic surgical instrument can only be done by a highly skilled doctor, so the endoscopic operation is limited, so the use of The loop knot is made in vitro, and the surgical site of the blood vessel or other organs is covered in the abdominal cavity before ligation. However, because the sealing wire is too soft and cannot maintain a certain loop shape, it is difficult to loop. Surgical site

In order to ligate the ferrule covering the surgical site, it is required to ligate the sealing wire after being tightened safely, but the knot is not in a fixed state, so it is quite difficult to meet the above requirements

In the early stage, dry feline intestinal silk is often used. The disadvantage is that although it can easily cover the part to be ligated, it is absorbed too quickly in the body, so that the safety of the patient cannot be guaranteed during the recovery period.

A variety of absorbable sealing wires developed recently have poor hardness, and it is not easy to trap the sealing part in the body during surgery

In order to solve this problem, a hardening agent is applied on the surface of the sealing wire to keep it in a circular ferrule shape, but the sealing wire treated with the hardening agent is very smooth and easy to loosen the bundled knot, thereby causing the rupture of the surgical site. situation, had to do another operation

Also there is a problem, in order to cut off the sealing wire of ligature during operation, must take out surgical instrument from the other side of the sleeve of trocar needle, then send into scissors to cut off sealing wire, or cut off with used scissors, like this There is also the problem of unsanitary
