Abstract

The present invention provides an operation clamp, which combines the functions of cutting and ligation. The operation clamp is used in conjunction with a ligation ring formed of two sutures into a deformed operation knot. When in use, the two ligation rings are installed in parallel at the opening of the operation clamp, and can be controlled by the operation clamp to shrink in size in order to complete a ligation function. The design of the operation clamp integrates the functions of an operation knife, a clamp, and simulated fingers. When a surgeon operates the device independently, the operation clamp can be used to clamp a target, and a knife is used to open the tissue, an then the two ligation rings each fasten a vascular pedicle and cut off an excessive suture. Thus, an operation is carried out faster and more convenient, and is particularly suitable for an operation in a narrow space, e.g. an endoscopic operation.
