Needle forceps for intracavitary knotting in laparoscope operation

Abstract

The invention relates to needle forceps for intracavitary knotting in laparoscope operations. The needle forceps consist of a needle forceps clamp, a knotting rail, a knotting guide wire, a line drawing guide wire, a knot pushing guide wire and handles; the needle forceps clamp is arranged at the frontmost end; the knotting rail is connected to the rear part of the needle forceps clamp; the knotting guide wire is arranged in the knotting rail; the line drawing guide wire is connected to the rear part of the knotting rail; the knot pushing guide wire is arranged on the side of the line drawingguide wire; and the handles are arranged on the rear part. The needle forceps solve the problem of high difficulty in suturing and knotting in the laparoscope operation, and a knotter is arranged at the front end in the instrument. The head of the instrument is provided with the improved strong-force needle clamp. After suture is performed and a needle is pulled out, the internal line drawing guide wire pulls a line into the instrument, the line is knotted by the knotting guide wire, a knot is pushed out by the knot pushing guide wire and place at a target position, the whole instrument is not required to be assisted by electricity, and suture operation under a laparoscope can be simplified; a titanium clamp is replaced in a wide range, operation cost is reduced, and operation time is saved; and many original open operations can be changed into the laparoscope operations.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a knotted needle-holding forceps in an endoscopic surgery cavity. Background technique [0002] In today's laparoscopic surgery in clinical surgery, titanium clips are often used to close blood vessels and other pipelines. When suturing on the plane, the Endo-Stich is also used from time to time. If you want to tie a surgical knot like ordinary direct vision surgery, you need to tie the knot outside the body and then push it into the body. No matter which of the above methods has its own disadvantages, such as high price, many adverse reactions, weak closure, not suitable for non-planar sutures, and long time-consuming, etc. [0003] About the key technology of the present invention, only the structure of surgical knot. Surgical knots are the standard for tying knots in surgery today and consist of a straight knot and a reverse knot. Through observation, the applicant foun...
