A kind of lying external bone fixator

Abstract

The invention relates to a lie-flat bone external fixator which comprises a horizontal bracket, a body external fixator and a longitudinal fixator; the longitudinal fixator comprises an external frame and a bone surface fixing assembly; the body external fixator comprises a support device; the support device comprises a connecting bar and fixing rings arranged on two sides of the connecting bar; the external frame is fixed on the connecting bar in an arrayed manner; one side of the external frame is embedded on the connecting bar; the bone surface fixing assembly comprises a plurality of fixing blocks; fixed cables are arranged among the fixing blocks; the fixing blocks are arranged on the external frame; the fixed cables define a support frame by means of the fixing blocks. According to the lie-flat bone external fixator, by match of the external frame and tensioning wires, the tensioning wires with smaller diameters form one or more fixed meshes under the support of the external frame, and thus the matching with bones is realized. Since the tensioning wires are low in elasticity, the fixation of the bones can be ensured, and osteonecrosis caused since the surfaces of the bones are excessively compressed by the tensioning wires can be avoided.

Description

technical field [0001] The invention relates to a flat-lying external bone fixator, in particular to an external bone fixator that allows a patient to lie flat. 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 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. After the traditional external fixator is installed, the human body itself Due to the effect of the external steel nails, it is impossible to lie flat, and the comfort is very poor, so it is not suitable for postoperative recovery; [0003] In this regard, on the market now, many orthopedi...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: to overcome the technical problems that the bracket in the prior art cannot allow the patient to realize the platform, and at the same time, the installation trauma is large and the fixation operation is complicated, and to provide a patient who can lie flat after surgery, and at the same time cause less trauma to the patient. Orthopedic fixation brackets that can reduce or even eliminate secondary surgery
