A kind of automatic wire drawing pliers

Abstract

The invention discloses a pair of automatic suture drawing forceps. In use, a forceps jaw tightly clamps a suture required to be drawn out by controlling a movable handle and a fixed handle, a motor is started to drive a driving belt to rotate after clamping is completed. Due to the fact that the driving belt is arranged on a rotating shaft of a longitudinal bevel gear of a steering gear in a sleeving mode, and the longitudinal bevel gear is also driven to rotate during rotation of the driving belt. Due to the meshing effect of the longitudinal bevel gear and a transverse bevel gear, the longitudinal bevel gear drives the transverse bevel gear to rotate, a driving rotor connected with the transverse bevel gear also begins to rotate. Due to the friction effect between a driven rotor and the driving rotor, the driven rotor begins to rotate. The clamped suture is drawn out through rotation of the driving rotor and the driven rotor, and the motor is stopped rotating after the suture is drawn to some degree. By adopting the pair of automatic suture drawing forceps, the suturing operation difficulty in the minimally invasive surgery process is reduced, the surgical time is shortened, and the surgical safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic wire drawing pliers. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods, coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. [0003] Laparoscopic surgery is also known as "keyhole" surgery. Using laparoscopic technology, the doctor only needs to make a few "keyhole" holes around the patient's surgical site, and can visually observe the patient's internal situation in front of the computer screen without opening the abdomen, ...

AI Technical Summary

Problems solved by technology

[0004] However, when using tissue forceps for surgery, first of all, because the suture needle is in a free state during the thread pulling process, it is difficult to find the suture needle at the end; It takes too long to pull out the wire, which leads to a prolonged operation time; finally, due to the complexity of the wire pulling process, the difficulty of the operation increases and the safety decreases
