Embodiment 1

[0042] The external bone fixator mainly includes a number of longitudinal fixators and connecting brackets used to connect and fix each longitudinal fixator. At the same time, there are external fixators used to fix the limbs at both ends of the bracket. This product is mainly used for bone fixation. The longitudinal fixer is improved and the original steel nail fixation is cancelled;

[0043] Specific as figure 1 As shown, the longitudinal fixer in this product mainly includes several fixing blocks 1, and fixed cables 3 are arranged between the fixing blocks 1, and the fixing blocks are fixed on the outer frame 2, and the fixing cables 3 pass through The positioning of the fixed block on the outer frame 2, thereby enclosing the support frame;

[0044] where fixed blocks (such as Figure 4 shown) includes a sliding hole 1-2 for fitting the fixing block 1 onto the outer frame 2, a locking screw B is arranged on the inner wall of the sliding hole 1-2, and a locking screw B is ...

Embodiment 3

[0059] 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 an external skeletal fixator, which comprises a transverse support frame, an external fixator and a longitudinal fixator, wherein the longitudinal fixator comprises an outer frame and a bone surface fixing assembly, the bone surface fixing assembly comprises a plurality of fixing blocks, fixing cables are arranged among the fixing blocks, the fixing blocks are fixedly arranged on the outer frame, and a support framework is defined among the fixing cables through the fixing blocks. The external skeletal fixator has the advantages that the matching of the outer frame and tensioning wires is adopted, one fixing mesh or a plurality of fixing meshes is / are formed through the tensioning wires with the smaller diameter under the support effect of the outer frame, the matching on the bone is realized, the tensioning wires have low elasticity, the bone fixation can be ensured, and meanwhile, the bone necrosis due to excessive compression of the tensioning wires on the bone surface can be prevented.

Description

technical field [0001] The invention relates to an external fixator for bone, and relates to an external fixator for bone which adopts cables to fix bone. 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 ...
