Embodiment 1

[0041] This product is mainly an external bone fixator used for postoperative fixation and auxiliary recovery of fractures or misaligned joints. This product mainly uses two fixation rings for non-invasive fixation with the arms or legs on both sides of the joint and one A fixed cable structure for minimally invasive bone surface fixation to achieve minimally invasive fixation of joints;

[0042] Such as figure 1 As shown, this product mainly includes two outer frames and fixing rings 7 arranged on both sides of the two outer frames. The outer frame includes an outer frame 9 with a plate-like structure and an outer frame 11 with a net-like structure. Relative setting of outer frame;

[0043] Such as image 3 , The outer frame 11 resembling a net structure includes two splint assemblies 12 and a fixing rod 13. The splint assembly has an arc shape corresponding to the spherical shape of the joint. One side of the splint assembly is fixedly connected to the fixing ring 7. The splint ...

Embodiment 2

[0058] When fixing jointless structures such as thighs, such as Figure 5 As shown, first, the fixing ring 7 made of two cable ties is sleeved on both sides of the skin where the bone is broken, the fixing ring 7 is tightened, and then the outer frame 9 of the plate structure is fixed to the side of the thigh facing the back. During specific processing, the two can be processed into screw fixation, and then the fractured femur (bone C6) is fixed by the fixing cable 3. After the fixation is completed, one end of the fixing cable 3 passes through the fixing hole 10. It is fixed by the fixing block 1, and then the fixing rod 13 is installed in the middle of the two fixing rings 7 through the upper splint and the lower splint. At the same time, the fixing block 1 is set on the fixing rod 13 corresponding to the exit position of the fixed cable. The other end of the fixing cable 3 is fixed to the fixing block 1 to realize the fixation of the entire femur; at the same time, the fixin...

Description

Technical field [0001] The invention relates to an external bone fixator for joints, and relates to an external fixator for bone fixation of joints by using cables. Background technique [0002] In orthopedic treatments such as fractures, various stents are often used to penetrate the skin after the operation to fix the bones to restore them. After recovery, the stents are removed through trauma surgery. The entire process requires multiple operations. The trauma to human muscles and epidermis is relatively large, and the postoperative recovery period is relatively long. At the same time, traditional stents bring relatively large compression and trauma to the bones; [0003] In this regard, there are many orthopedic fixators available on the market that can reduce the degree of trauma during surgery and the number of operations to a certain extent, and at the same time accelerate healing, such as the invention with patent number ZL201120537796.6, which proposes a The steel wire wr...
