Abstract: The present disclosure discloses a knot-tying device and a knot-tying system with the knot-tying device. The knot-tying device comprises a shear knife provided at a front end of a driving rod. Hilts of the shear knife (18) are opened by an elastic member, and the hilts are pressed by the driving rod to close and cut a suture. The shear knife is used as a substitute for a cutter in the related art, and is driven to close by the driving rod so as to realize a shearing function. When the suture is cut off by the shear knife, a requirement for sharpness of blades are greatly reduced, and the blades are able to be realized by a common processing method, thereby greatly reducing cost while ensuring reliability. In addition, abrasion on the blades from the suture is reduced, thereby greatly prolonging the service life of the product.

Abstract: Some embodiments of the present disclosure provide an integrated electrode, the integrated electrode includes an electrode wire and an electrode base. The electrode wire is provided in a hollowed-out shape, and several through holes are punched on a side face of the electrode wire without changing the appearance and dimension of the electrode wire. The electrode base is formed by an injection molding process, and is integrally connected with the electrode wire by means of a one-time injection molding. During a process of injection molding, plastic fluid can flow through the hollowed-out through holes of the electrode wire so as to fix the electrode wire in the electrode base, such that the electrode wire and the electrode base are integrated.
