Abstract

The invention relates to the technical field of surgical instruments, and provides a knotter and a knotting system with the knotter. Wherein, the knotter includes a shearing knife arranged at the front end of the transmission rod, the handle of the shearing knife is stretched by an elastic member, and the handle is closed and cuts the suture under the extrusion of the transmission rod. The knotter of this scheme adopts the shearing knife to replace the cutting knife of the prior art, and drives the shearing knife to close through the transmission rod to realize the shearing function. Obviously, when the suture is cut with scissors, the sharpness of the blade is greatly reduced, which can be achieved by ordinary processing methods, thereby greatly reducing the cost while ensuring reliability; The wear is reduced, which greatly prolongs the service life of the product, and can realize the thread cutting function after knotting faster and better.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a knotter and a knotting system with the knotter. Background technique [0002] Traditionally, there are various disadvantages when the knotting of deep parts is completed by manual winding. For example, it is time-consuming and labor-intensive, and it is necessary to manually cut the suture with scissors after repeated several times, and the knotting effect and success rate depend too much on the proficiency of the operator. [0003] In order to solve the above problems, the patent No. CN202892020U discloses a minimally invasive knotting system, which can be sutured and knotted in a minimally invasive environment, and is mainly suitable for minimally invasive replacement of heart valves and all intrathoracic soft tissue repairs. Deep stitching. The minimally invasive knotting system is easy to operate, and the operation of cutting the suture can be completed at th...
