Description
Technical Field
The invention belongs to the technical field of medical instruments, relates to a fixing device, and particularly relates to a medical knee ligament fixing and correcting device.
Background
The main components of the ligament are collagen fiber and elastic fiber, the collagen fiber enables the ligament to have certain strength and rigidity, and the elastic fiber enables the ligament to have the capability of extending under the action of load. Most fibers of ligaments are arranged nearly in parallel, so that they have more and more specific functions and usually bear loads in only one direction. Because ligaments are tough, they can strengthen the stability of bones, and can hold internal organs in place, limiting their range of motion. The main ligaments in the human body include knee joint cruciate ligament, inguinal ligament, coracoid ligament, radial collateral ligament of elbow joint, ulnar collateral ligament, etc. The knee joint is one of the joints which are most easily injured by human bodies, and the stability of the knee joint is mainly maintained by a series of structures inside and outside the knee joint, including a bony structure, an articular outer structure and an articular inner structure; the bony structures mainly comprise a patella, a distal femoral condyle and a tibial condyle; the medial-lateral tetrad complex in the articular outer structure is considered as the main knee joint stable structure, the medial tetrad complex is composed of medial collateral ligaments, semimembraneous muscles, goose-foot tendons and posterior oblique ligament parts of a posterior joint capsule, and the multiple ligament injury of the knee joint generally refers to the ligament injury of 2 or more than 2 of 4 main ligaments of the knee joint, so that the serious knee joint instability and dysfunction are caused, blood vessel and nerve injuries are often accompanied, and the clinical treatment is relatively complex. The ultimate goal of treating ligament injury is to maximize recovery of function of the injured limb and thus, in the treatment of ligament injury, two basic principles of immobilization and functional exercise are important. Fixation means that the ligament is damaged and should not be moved further, so that it should be fixed at a satisfactory position by different methods to heal it gradually, and the commonly used methods include: the function exercise, the correction exercise of renaming, through injured limb muscle contraction, increase the blood circulation of ligament surrounding tissue, promote ligament healing, make the function of injured ligament resume to the normal condition before injury as early as possible. Most of the existing fixing devices are heavy and do not have the adjusting capacity, and meanwhile, the knee ligament correcting and exercising capacity is not provided.
