An orthopedic calf tibial external fixation bracket

Abstract

The invention discloses a shank shin bone outer fixing support for the orthopedics department. An upper nail rod fixing clamp assembly (A) of the support comprises an upper fixing clamp (2) and an upper thread nail (3), a lower nail rod fixing clamp assembly (B) comprises a lower fixing clamp (4) and a lower thread nail (5), a support main body (1) comprises a main screw rod (1a) and an anti-rotating rod (1b), the main screw rod and the anti-rotating rod are arranged in a left-and-right spaced mode and are fixedly connected together through a connecting portion (1c), the upper fixing clamp and the lower fixing clamp are alternately arranged on the main screw rod in a penetrating mode, and are locked on the main screw rod through main nuts (6), meanwhile, the anti-rotating rod penetrates through the upper fixing clamp and the lower fixing clamp to prevent the upper fixing clamp and the lower fixing clamp from rotating around the main screw rod, an upper nail rod and a lower nail rod are arranged between the main screw rod and the anti-rotating rod, and the main nuts are twisted to adjust the positions of the upper nail rod fixing clamp assembly and the lower nail rod fixing clamp assembly on the main screw rod. The shank shin bone outer fixing support has the advantages of being novel in structure, ingenious in design, high in universality, good in stability, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to an orthopedic external fixation bracket in medical equipment, in particular to an orthopedic external fixation bracket for the calf and tibia. Background technique [0002] The orthopedic external fixator is an external fixation device, which connects each end of the fracture with one or more longitudinal rods (tubes) and / or rings through metal bone nails to achieve stability and reduction. [0003] Existing orthopedic external fixation brackets come in various forms, but generally can be divided into three types: annular, semi-annular and unilateral. The orthopedic external fixation bracket with unilateral structure appeared later than the annular and semi-annular structures, and has the characteristics of compact structure, low manufacturing cost, and easy wearing. The orthopedic calf and tibial external fixation bracket with unilateral structure is mainly composed of a fixing bracket, an upper nail rod fixing clip assembly ...

AI Technical Summary

Problems solved by technology

The orthopedic calf and tibial external fixation bracket with unilateral structure is mainly composed of a fixing bracket, an upper nail rod fixing clip assembly and a lower nail rod fixing clip assembly installed on the fixing bracket, and the upper nail rod fixing clip assembly is mainly composed of an upper fixing clip, a through The upper threaded nail passing through the upper fixing clip is formed, and the lower nail rod fixing clip assembly is mainly composed of the lower fixing clip and the threaded nail passing through the lower fixing clip. There is no mobile adjustment function component. The main problems of the existing structure are: (1) The upper and lower nail rod fixing clip assemblies cannot move mutually on the bracket main body screw, cannot compress the broken end of the fracture or cannot adjust the bone thread screw or the adjustment mechanism is too complicated; (2) the upper and lower nail rod fixing clip assemblies are installed and used Rotation may occur during the process, and the stability is not good, which affects bone healing
