The fracture external fixation brace comprises a first bracket, a second bracket anda steel needle, and the first bracket and the second bracket are integrally assembled; at least one of the second bracket and the first bracket is provided with a base, the base is provided with a fixing hole, a clamping groove and a base through hole, and the fixing hole is communicated with the base through hole; a fixing plug is installed in the base through hole and provided with a limiting ring, a locking hole and a steel needle through hole, and the limiting ring cannot penetrate through the base through hole; the part, provided with the locking hole, of the fixing plug is loaded into the base through hole, the locking hole is communicated with the fixing hole, one end of the steel needle penetrates through the steel needle through hole, pierces through the skin and the muscle and then is fixedly assembled with the bone, and the other end of the steel needle is provided with an outer thread; the outer thread can be assembled with a threaded hole formed in an adjusting nut through threaded screwing, the clamping groove can be clamped and assembled with a clamping half shaft, the clamping half shaft is arranged on a clamping piece, and the clamping piece is further provided with a stress part.

Description

Technical field [0001] The invention relates to an external fixation brace after fracture, in particular to a fracture external fixation brace based on 3D printing and a manufacturing method thereof. Background technique [0002] In traditional fracture surgery, external fixation brackets need to be installed to correct the fracture. The main defects of the current external fixation bracket are: [0003] 1. The installation process needs to be completely relied on the operator's experience to be reset and temporarily installed on site, lacking preoperative planning. [0004] 2. During the installation process, the C-arm machine is needed to help determine the appropriate reset angle and reset situation to ensure the installation of the external fixing bracket. [0005] 3. The external fixation bracket worn by the patient is too heavy and inconvenient in daily life. Summary of the invention [0006] In view of the above-mentioned shortcomings of the prior art, the technical problem to...
