Abstract

The invention relates to a tibial fixator. The tibial fixator comprises a horizontally-arranged fixing board, on which multiple first toothed gears capable of horizontally rotating are arranged. The multiple first toothed gears are distributed along the length direction of the fixing board. Vertical sliding grooves, corresponding to the first toothed gears, are arranged in the fixing board. Sliding blocks and springs are disposed into the vertical sliding grooves. The sliding blocks are provided with rectangular through holes which penetrate forward and backward through the sliding blocks. The back parts of the first toothed gears are disposed into the rectangular through holes. The lower ends of the sliding blocks are hinged onto compression semi-rings. The sliding blocks are provided with vertical rotating shafts above ball bodies. Upper ends of the rotating shafts penetrate through the sliding blocks. Lower parts of the rotating shafts are in threaded connection with the sliding blocks. Second toothed gears and eccentric wheels are arranged in the rectangular through holes. The second toothed gears are engaged with the first toothed gears. The second toothed gears and the eccentric wheels are vertically and slidably connected with the rotating shafts. Slidable toothed gears are arranged on the fixing board. The toothed gears are engaged with the first toothed gears. Bonding strips and connection blocks are arranged on the sliding blocks. The connection blocks are provided with through holes for the bonding strips and eccentric locking wheels. When the eccentric locking wheels rotate, large ends of the eccentric locking wheels can be disposed into the through holes for the bonding strips.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tibial fixator. Background technique [0002] In the treatment of traumatic orthopedic fractures, it is usually divided into three main steps: reduction, fixation, and healing. Fixation is the connecting link between reduction and healing. Good fixation not only consolidates the effect of reduction, but also promotes the speed and quality of healing. It has many beneficial effects such as relieving pain, reducing the pain of the wounded, preventing the aggravation of the injury, protecting the wound, preventing infection, and being convenient for patients to transport. [0003] At present, the commonly used fracture fixation method is mostly splint clamping fixation method. Although this method is easy to implement, it requires high operation during fixation. In general, human bones are not absolutely straight lines or regular curves. For example, although it is lo...
