Abstract

The invention provides a hand bone fixer which comprises a wrist restraining device, a palm fixer and a bone surface fixing component, wherein the wrist restraining device comprises a wrist fixing ring and an arm wrapping plate; the arm wrapping plate is rotatably connected with the palm fixer by virtue of the wrist fixing ring; the bone surface fixing component is arranged between two supporting components of the palm fixer; the bone surface fixing component comprises fixing blocks arranged on a fixing rod; fixing cables are arranged among the fixing blocks; the bone surface fixing component is capable of realizing skeletal fixation by virtue of a skeletal fixation frame consisting of a plurality of fixing cables contacted with a bone surface.

Description

technical field [0001] 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 [0002] 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; [0003] In this regard, on the market now, many orthopedic fixators that can reduce the degree of trauma during surgery and reduce the number of operations to a certain extent, and can accelerate healing at the same time, such as the invention o...
