Abstract

The invention relates to a noninvasive hand bone fixer for preventing osteonecrosis. The hand bone fixer comprises a wrist restraining device, a palm fixer and a bone face fixing assembly. The wrist restraining device comprises a wrist fixing ring and an arm wrapping plate. The arm wrapping plate and the palm fixer are rotationally connected through the wrist fixing ring. The bone face fixing assembly is arranged between two supporting assemblies of the palm fixer. The bone face fixing assembly comprises fixing blocks arranged on a fixing rod, and fixing cables are arranged between the fixing blocks. According to the bone face fixing assembly, the bone is fixed through a bone fixing frame composed of the multiple fixing cables making contact with the bone face.

Description

[0001] This application is a divisional application. The original patent number is: 201410578178.4, the application date: October 24, 2014, and the invention name is: a hand bone fixator. technical field [0002] The invention relates to a hand bone fixator, which relates to an external bone fixator for fixing the bone of the hand through the cooperation of cables and the hand fixator. Background technique [0003] In the process of orthopedic treatment such as fractures, various brackets are often used to penetrate the skin surface after surgery to fix the bones to restore them. After recovery, the brackets are removed through trauma surgery. The whole process requires multiple operations. The trauma caused to the human muscle and epidermis is relatively large, and the postoperative recovery period is relatively long. At the same time, the traditional brackets cause relatively large compression and trauma to the bone; [0004] In this regard, on the market now, many orthop...
