Problems solved by technology

[0003] The traditional device to achieve bone lengthening is a ring-type external fixator, but the structure of the ring-type external fixator is complex and difficult to adjust. The installation needs to be drilled around the bone surface. The bone surface is traumatized, and needles are easy to damage nerves, blood vessels and Tissue; in the process of bone elongation and fixation, it is difficult to care for and inconvenient to live, and the direction of bone growth may shift at any time, which needs to be adjusted at any time during the whole process, but the ring-type external fixation bracket is difficult to adjust; the unilateral orbital fixation bracket has only one support The fixed track, the sliding block on it may be unstable and loose during the bone lengthening and fixing process, and it is prone to problems such as poor alignment of the broken ends and difficulty in adjustment

Abstract

The invention discloses an improved unilateral double-track bone moving outer frame. The improved unilateral double-track bone moving outer frame is characterized by comprising a first sliding rod, asecond sliding rod, moving blocks and fixing screws. The bone moving outer frame is designed into unilateral fixation and double tracks, the moving blocks used for being connected with the fixing screws are more stable, the unilateral fixation can conveniently correct the position of a broken bone in the whole bone lengthening process, the position of the broken bone can be finely adjusted only byadjusting the fixing screws, and it is guaranteed that the deviation of the bone growth joint is minimum after healing; the more the joint is folded, the faster and firmer the bone healing is; and few holes are drilled in the bone, the bone surface is slightly injured, and important tissues such as nerves and blood vessels are not easily injured.

Description

technical field [0001] The invention belongs to the field of orthopedic medical instruments, and in particular relates to an improved unilateral double-track bone transfer outer frame. Background technique [0002] Bone transfer device is a special device for bone lengthening. Bone transfer is distraction osteogenesis, which is mainly aimed at bone regeneration of bone defect. Soft tissue and blood supply, the bone transfer device fixes the two ends of the bone, and slowly pulls the truncated free bone end towards the defect, continuously stimulates the body tissue, stimulates the regeneration potential of the body tissue, makes the osteotomy gap form new bone, and reaches the bone. the purpose of regeneration; [0003] The traditional device to achieve bone lengthening is a ring-type external fixator, but the structure of the ring-type external fixator is complex and difficult to adjust. The installation needs to be drilled around the bone surface. The bone surface is trau...
