Combined multi-functional physiological bone compression bone external fixation bracket adopts convex pressure device and physiological bone pressure device to realize multi-segment different types of fractures, and the broken end of the bone restores the physiological pressure stress of the original fracture site of the human body.

The reasoning of the data calculation method of physiological compressive stress (see Figure 1 to Figure 4), the oblique fracture of the tibia with the method in the 1990s, the bone ends overlapped and shifted, and the bone ends of the oblique fracture showed overlapping displacement (see Figures 1 and 3 ), the overlapping displacement is caused by the contraction tension of the soft tissue of the fracture segment, such as skin, muscle, tendon, fascia, blood vessel, etc. First use a small splint for external fixation, do calcaneal traction, start with a 6KG weight, after three days the overlapping tibial fracture has been corrected by traction, then change the weight to 2.5KG, maintain the weight until the fracture heals, remove the calcaneal traction, remove the external fixator splint. Now 3KG is defined as the physiological compressive stress. The physiological compressive stress 3KG of the present invention applies pressure after the anastomotic contact of the broken end of the bone, and restores the original physiological compressive stress of the fracture segment, so that the intramedullary and outer callus of the broken end of the fracture can be formed to achieve fracture healing. purpose of treatment.

Physiological bone compression refers to the analysis and judgment of the physiological pressure stress value of the fracture end according to the fracture site, fracture type, and physiological pressure stress of the fracture patient, and determines the rotation of the dynamic screw to move the pointer line of the pointer screw to achieve pressure on the bone end. Reach physiological compressive stress and improve fracture healing rate. After the operation, the pressurizer can be disassembled to reduce weight, reduce trouble, and facilitate portability.
