Multifunctional assembled physiological bone pressure bone exterior fixation bracket, volume is little, lightweight, and the pressurization of broken ends of fractured bone physiological bone is flexible, safety, simple to operate, improves cure rate, avoids the infection of bone brought during Open fracture treatmeT.
Multifunctional assembled physiological bone pressure bone exterior fixation bracket, adopt convex prelum and physiology prelum, achieve the dissimilar fracture of multistage, bone stump has recovered the Physiological Pressure stress of the original fracture site of human body.
The method for computing data reasoning (see Fig. 1 to Fig. 4) of Physiological Pressure stress, the method oblique fracture of tibia of the nineties, the displacement of bone stump overlap, oblique fracture bone stump is shifted (see Fig. 1 and Fig. 3) in an overlapping, overlapping displacement is by fracture segment soft tissue, as the shrink tensions such as skin, muscle, tendon, fascia, blood vessel cause.First use Set by small splints from outside, do calcaneal traction, start to use 6KG weight, overlapping fracture of tibia traction correcting after three days, then changing weight is 2.5KG, maintains weight until union of fracture, removes calcaneal traction, remove extenal fixation plintlet.Now 3KG is decided to be Physiological Pressure stress, Physiological Pressure stress 3KG of the present invention coincide at bone stump to contact after-applied pressure, has recovered the primary reason compressive stress of fracture segment, just can make the inside and outside callus formation of fracture site marrow, reached the object of union of fracture treatment.
Combination type: each parts of external fixed support for bone can according to patients with fractures position, classification of fracture, local soft tissue damage, dissection individuation are accurately selected, and are applicable to various external fixation of fracture treatment, improve the cure rate of complicated fracture.
Multi-functional: external fixed support for bone can complete human limb each position reduction of the fracture extenal fixation, can with dismountable convex prelum to fresh fracture, can pressurize to needs bone pressurized portion fracture site bone at any time, after pressurization, convex prelum can be disassembled, weight reduction, reduces trouble, and is convenient for carrying.
External fixed support for bone of the present invention can be scratched bone each position fracture, multiple fracture and single fracture and treat tibia, femur, humerus chi, postoperatively prelum can be dismantled.
Physiological bone pressurization refer to according to fracture patient fracture site, classification of fracture, Physiological Pressure stress difference analyze judge fracture site Physiological Pressure stress numerical, determine rotational power screw, the cursor line of pointer screw is moved, realize pressurizeing at bone stump, reach Physiological Pressure stress, improve union of fracture rate.Postoperatively prelum can be dismantled, weight reduction, reduces trouble, and is convenient for carrying.
