Embodiment 1

[0049] The external bone fixator mainly includes a number of longitudinal fixators and connecting brackets for connecting and fixing each longitudinal fixator. Figure 7~9 As shown, the external fixator includes a supporter, the supporter includes a connecting strip 13 and a fixing ring arranged on both sides of the connecting strip 13, the outer frame 2 is fixed on the connecting strip 13 in an array, and one side of the outer frame 2 is inlaid on the On the connecting bar 13, the plane where the outer frame 2 is located is perpendicular to the axis of the connecting bar 13, and a support frame is arranged in the middle of the outer frame 2. The support frame includes a pillar 8 and a fixed plate. cable ties for body parts 14;

[0050] The fixed ring includes a fixed ring body 9, a locking assembly and a support assembly, and the support assembly includes a positioning assembly and an arc-shaped support plate 10 of the same height as the support frame. On the surface, the ar...

Embodiment 3

[0068] At the same time, the present invention can cross-connect the fixed cables between the fixing blocks of different longitudinal anchors, for example, there are three longitudinal anchors for fixing, including longitudinal anchor A, longitudinal anchor B, and longitudinal anchor C , each vertical fixer includes 4 fixing blocks, among which the four fixing blocks of longitudinal fixer A are respectively marked as fixed block AI, fixed block AII, fixed block AIII, and fixed block AIV. The fixed block AI on A can be connected with the fixed block BII of the longitudinal fixer B through a fixed cable, and at the same time, the fixed block AII on the longitudinal fixer A and the fixed block CIV on the longitudinal fixer C are connected through a fixed cable, Two fixation cables form a supporting frame in contact with the bone surface.

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...
