Description

Technical Field

[0001] The utility model relates to the field of orthopedic medicine, in particular to a mechanical adjustment bone and joint fixation device. Background Art

[0002] With the development of chemical material technology and molecular material technology, various new orthopedic external fixation devices have emerged continuously. External fixation devices are widely used in the treatment of fractures and deformities, and are divided into small splints, plaster bandages, thermoplastic splints, polymer bandages, detachable foam splints and braces, etc. Existing external fixation materials are prone to cause various degrees of complications, including: pain, fracture, skin breakdown, swelling, joint stiffness and other symptoms.

[0003] The ultimate goal of most existing treatments for fractures and joint dysfunction is to maximize the recovery of the injured limb. Generally, bones and joints need to be fixed to restrict their movements before healing. Existing bone and joint fixation devices do not have the ability of power adjustment, cannot realize mechanical assistance for self-adjustment treatment and rehabilitation, and the recovery effect cannot reach the expected goal. Moreover, most existing bone and joint fixation devices use elastic bands for fixation. After long-term use, the device will become loose and the fixation will not be firm enough. Therefore, the technical personnel in this field provide a mechanical adjustment bone and joint fixation device to solve the problems raised in the above background art. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a mechanical adjustment bone and joint fixation device, which has the function of mechanically adjusting bones and joints to facilitate the recovery of patients, and also has the functions of fixing bones and joints more firmly, having a closer connection, and a longer service life.

[0005] To achieve the above purpose, the utility model provides the following technical solution:
