Safety, it is simple to operate, cure rate is improved, avoids the infection of bone brought during Open fracture treatmeT.
Multifunctional assembled physiological bone pressurization external fixed support for bone, using convex pressurizer and physiological bone pressurizer, is realized
Multistage different type fracture, bone stump have recovered the physiology compression of the original fracture site of human body.
The method for computing data reasoning (referring to Fig. 1 to Fig. 4) of physiology compression, the method oblique fracture of tibia of the nineties,
The overlapping displacement of bone stump, oblique fracture bone stump shift (referring to Fig. 1 and Fig. 3) in an overlapping, and overlapping displacement is by soft group of fracture segment
Knit, as caused by the shrink tensions such as skin, muscle, tendon, manadesma, blood vessel.Set by small splints from outside is used first, does calcaneal traction,
Start to use 6KG weights, overlapping fracture of tibia traction correcting after three days, it is 2.5KG then to change weight, maintains weight until fracture
Healing, calcaneal traction is removed, remove outer fixed plintlet.3KG is set to physiology compression, physiology compression of the invention now
3KG is coincide the after-applied pressure of contact in bone stump, has recovered the primary reason compression of fracture segment, can just make in fracture site marrow,
External callus is formed, and reaches the purpose of union treatment.
Combined type：Each part of external fixed support for bone can be according to patients with fractures position, classification of fracture, local soft tissue damage
Wound, dissection individuation are accurately selected, and are treated suitable for various externals fixation of fracture, are improved the cure rate of complicated fracture.
It is multi-functional：External fixed support for bone can be completed to fix outside each position reduction of the fracture of human limb, and fresh fracture can use
Dismountable convex pressurizer, after pressurization, convex can be pressurizeed at any time to needing bone pressurized portion fracture site bone to pressurize
Device disassembles, and mitigates weight, reduces trouble, be convenient for carrying.
The external fixed support for bone of the present invention can scratch bone each position fracture, multiple fracture and list to shin bone, femur, humerus chi
One fracture is treated, postoperative to be dismantled pressurizer.
Physiological bone pressurization refers to judge bone according to fracture patient fracture site, classification of fracture, the different analyses of physiology compression
Fracture end Physiological Pressure stress numerical, determines rotational power screw, moves the cursor line of pointer screw, realize and add in bone stump
Pressure, reach physiology compression, improve union rate.It is postoperative pressurizer to be dismantled, mitigate weight, reduce trouble, side
Portable belt.
