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 () 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.
