Abstract

The invention relates to a vertebra fixator, which comprises a connecting rod and at least two fixing sections, wherein each fixing section comprises an external vertebrate top frame, an external vertebra surface fixator and a supporter, the supporter is an arc-shaped unfolding surface, a plurality of hollow grooves vertical to the longitudinal axial line of the unfolding surface are formed in the unfolding surface of the arc surface, fixing rods are arranged in the hollow grooves, at least one fixing block is respectively arranged at each of two sides of each fixing rod, a fixing cable is arranged between the fixing blocks, an upright post is arranged in the middle part of the supporter, the external vertebrate top frame is arranged on the upright post and comprises an arc-shaped support surface coaxial with the unfolding surface of the supporter, a support framework used for fixing the vertebrate is defined between the arc-shaped support surface and the fixing cables arranged among the fixing joints, an installing hole parallel to the axial line of the arc-shaped support surface is arranged in the upright post of the supporter, and the supporter is connected through a connecting rod arranged in the installing hole.

Description

technical field [0001] The invention relates to a spinal bone fixator, in particular to an external bone fixator using cables for rib fixation. 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 of ZL201120537796.6, which proposes a method for The st...
