Abstract

The invention discloses a tendon taking device. The tendon taking device comprises a hollow rod, a first rod body movably arranged in the hollow rod in a penetrating mode and an opening ring with oneend connected with the end part of the first rod body, wherein an opening of the opening ring faces the hollow rod, and the opening ring can be combined with the hollow rod to form a closed ring. According to the tendon taking device, the opening ring is arranged, so that a tendon to be taken down can be hooked conveniently; the first rod body is movably arranged in the hollow rod in a penetratingmode, and after the opening ring hooks the tendon, an operator pulls the first rod body to enable the opening ring and the hollow rod to be combined to form the closed ring, so that the situation that the tendon falls off from the opening ring in a process that the tendon taking device is pushed to separate the tendon from muscle tissue is avoided, and operation is easy and convenient. Through the conversion between opening and closing, the tendon taking device in the embodiment of the invention has the functions of opening the tendon taking device and closing the tendon taking device, so that the fulcrum of the tendon on the bone can be reserved, and only the tendon is separated from the muscle.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tendon harvester. Background technique [0002] In patients with clinical orthopedic sports trauma or car accident violence, the violence causes the knee joint to twist to generate huge shear and tension, and a single or multiple ligaments of the knee joint are ruptured, such as: rupture of the anterior and posterior cruciate ligaments of the knee joint, rupture of the medial and lateral collateral ligaments, Rupture of the patellar tendon; in the case of the Achilles tendon, direct or indirect violence can cause a rupture of the Achilles tendon, and if a complete rupture is not healed in time, contractures will occur at both ends of the rupture; in developmental diseases, such as patellofemoral arthropathy or trauma-induced patellofemoral Ligament damage. All of the above diseases require autologous or allogeneic tendon transplantation to reconstruct the continuity of ligam...
