Bone fixing device

Abstract

The invention discloses a bone fixing device. The bone fixing device comprises a baseboard and a fixing part, the fixing part comprises an attraction component, a fixed tong opening, a movable tong opening and a clamping component, the attraction component is located at the lower end of the fixed tong opening, is fixedly connected with the fixed tong opening and is fixed to the baseboard in a magnet attraction mode, the movable tong opening moves relative to the fixed tong opening to form opening and closing, and the clamping component can stop the movable tong opening from moving to keep a clamping state. Compared with the prior art, the operation is simple and fast, the work efficiency and precision of bone shaping can be improved, and the bone fixing device is easy to wash and disinfect at the same time.

Description

technical field [0001] The invention relates to a fixation device, in particular to a fixation device used for fixing bones in vitro, which is convenient for doctors to cut and shape bone blocks. . Background technique [0002] At present, in jaw repair and reconstruction surgery, free vascularized bone and muscle flaps are usually used for patients with large jaw defects. The commonly used bone and muscle flaps are fibula flap and iliac flap. Due to the irregular structure of the jaw, it is often necessary to perform three-dimensional shaping of the transplanted bone flap during surgery to meet the repair requirements. After the bone muscle flap is removed, it needs to be cut and shaped as soon as possible to make it conform to the shape of the jaw in the recipient area, and then the blood vessel anastomosis and fixation should be performed. However, at present, surgeons still use hand-held clamps to fix bone grafts. This operation has high requirements on the strength an...

Problems solved by technology

However, at present, surgeons still use hand-held clamps to fix bone grafts. This operation has high requirements on the strength and skill of the surgeon and assistants, and because each bone block needs to be clamped and fixed again, and Multiple cuts and adjustments are required to complete complex shaping, so using this method to fix the grafted bone for shaping often takes up a lot of surgical time and energy for the surgeon, and it is not easy to perform fine operations

In addition, the length of ischemia of the free skeletal muscle flap will affect the survival rate of the skeletal muscle flap, and the shaping effect of the skeletal muscle flap will also affect the jaw function and aesthetics of patients after surgery.
