Abstract

The invention discloses a pair of muscle tendon introducing forceps. The muscle tendon introducing forceps comprise an occlusion part, a traction part and an operating part, wherein the occlusion partis used for accommodating and fixing a broken end of a muscle tendon, a first end of the traction part is connected onto the occlusion part, the traction part is used for dragging the occlusion partto move in the axial direction, the operating part is connected onto a second end of the traction part and used for controlling the occlusion part to accommodate the broken end of the muscle tendon and fixing the broken end of the muscle tendon, the occlusion part comprises a first forceps head fixedly connected with the traction part and a second forceps head which is rotationally connected ontothe first forceps head and/or the traction part, an accommodating cavity used for accommodating the broken end of the muscle tendon is defined by the first forceps head and the second forceps head, the occlusion end of the occlusion part is set as a round opening for annularly hooping the broken end of the muscle tendon during occlusion of the first forceps head and the second forceps head, and alasso mechanism for fixing the broken end of the muscle tendon by tightening when the broken end of the muscle tendon is accommodated is arranged in the accommodating cavity; and the operating part isconnected with the second forceps head and controls the second forceps head to rotate relative to the first forceps head to realize opening and closing control for occlusion of the occlusion part, and the operating part is connected with the lasso mechanism and controls the lasso mechanism to tighten or loosen the broken end of the muscle tendon.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tendon guiding forceps used for pulling retracted tendons or guiding tendons through sheath tubes and internal passages in tissues. Background technique [0002] Proximal retraction often occurs when the tendon is damaged or ruptured. How to pull the retracted tendon through the tendon sheath or channel to reach the anastomosis of the tendon and keep the broken end and periaponeurosis intact is one of the key techniques for tendon repair. [0003] At present, hemostatic forceps or tendon probes are often used for tendon traction during surgery. For the hemostatic forceps, its disadvantages are: the distance of penetrating into the tendon sheath is small, forcibly pushing in may cause the sheath to tear; it is difficult to effectively open when passing through the distal tendon sheath, and the function of guiding the tendon cannot be achieved; it cannot follow the tendon...
