Definitions
- the present invention relates to the technical field of medical devices, and in particular, to a knotter.
- Minimally invasive surgery has the characteristics of small incision and fast recovery. At the same time, it requires the surgeon to achieve simple and fast postoperative suture and knotting operations in a minimally invasive surgical environment.
- knotting methods in the clinic manual knotting and device knotting.
- Existing surgical knotters generally clamp the suture by punching the clip to cause plastic deformation of the clamping member, and then cut the suture by the cutting knife or the cutting knife.
- the disadvantages of this cutting method are: when cutting with a cutting knife, first, the cutting knife needs to have a relatively high sharpness, the blade of the general material cutting knife is easily damaged, and second, the suture needs to be in a tight state, loose The suture thread of the blade is difficult to cut in the past; while the use of the shear knife, although the blade is not easy to cut the loose suture and reduce the sharpness of the blade, the handle of the shear knife is opened by the elastic member to maintain The cutter head is partially opened, and then the handle closes the cutter under the squeeze of the conveying rod to cut the suture. In the course of use, due to space limitations, the elastic member will have a problem of unstable operation.
