Abstract
The utility model relates to a three-track tooth type arched pressurizing steel plate for the connection of fractured bones, which comprises a base plate, reinforcement beams, pointed teeth and screw holes. The utility model is characterized in that three track type reinforcement beams are mutually in parallel and are arranged on the base plate; fixing screw holes which are used for adjusting fractured bones to restore positions are uniformly distributed in arched grooves among three tracks. In addition, the pointed teeth and the screw holes are uniformly distributed on the reinforcement beams. The track type reinforcement beams are adopted in the structure, so the utility model improves the bending strength of the steel plate. After inside fixation, each of the pointed teeth on the beams is fixed in bone cortex so that interlaced stress is formed. The utility model improves fixation functions of bending resistance force, sliding resistance, etc. and is particularly suitable for comminuted fracture.
Description
This utility model relates to a kind of living and treats the synthetism steel plate that the human fracture uses.
Be used for the treatment of at present the partes corporis humani position as: the synthetism steel plate of scratching fracture such as bone, ulna, humerus, femur and tibiofibula mostly is common plane synthetism steel plate, compression steel plate.The applicant has invented track arch form synthetism steel plate in 1988, though this synthetism steel plate has been received good effect on the treatment fracture, remedied some shortcomings, and by this clinical practice in several years, this kind synthetism steel plate remains in its shortcoming and deficiency.
1, steel plate arch radian is less, span is not enough, and circular skeleton (fracture) is not reached encirclement property fixation.Still have various component, distortion power, revolving force, bending power and offside side seam folding face segregation phenomenon.Exist eccentricity stressed.Stress force shelter reaction is arranged.Internal fixation is not firm, and disconnected plate and refracture danger are arranged.
2, this kind steel plate and other each steel plate still are powerless to comminuted fracture.At present comminuted fracture still there are not good method and apparatus.It is current treatment comminuted fracture a great problem.
The purpose of this utility model does not produce the tooth-like arch form pressurization of the three rails synthetism steel plate of component when providing a kind of synthetism, it designs according to anatomy, biology, biochemistry, bone fracture bone fracture disease Neo-Confucianism and mechanical stress.
This utility model is practice like this: it includes substrate, buttress brace, pointed tooth, screw hole, it is characterized in that substrate is provided with the rail mounted buttress brace that three affairs are parallel to each other, be evenly equipped with the fixing screw hole that is used for regulating the reduction of the fracture in the arch ditch between three affair tracks, on buttress brace, be evenly distributed with pointed tooth and screw hole.
Characteristics of the present utility model are:
1, the buttress brace of three rail mounteds and whole steel sheet are big arch (arc) type, and it encircles half cycle with skeleton (fracture) during internal fixation.Three row's screws and two row's pointed tooths are that the two isosceles triangle combined stresses of five lines are fixed.Thereby eliminated all various component, revolved ability, distortion power, eccentric force, stress-shielding effect and offside are decided phenomenons such as folding face separation.Increased anti-folding, bending resistance, combined stress such as anti-twist, improved Mechanics of Machinery and learned folding pathology fixation.
2, three track buttress braces have increased the steel plate rupture strength.Pointed tooth on the beam in each pointed tooth is nipped cortical bone behind the internal fixation, forms interweaving property and contains stress.It is moving to have strengthened anti-bone, anatomy and Mechanics of Machinery fixations such as resistance to bending.
3, three rail synthetism steel plates are because pointed tooth and Gong Gou are fit to the periosteum external fixation.The 2-3mm space is arranged between steel plate and the skeleton, form omnibearing tunnel, do not oppress periosteum and cortical bone.Guarantee normal bloodstain such as periosteum and cortical bone, prevented periosteum and the necrosis of cortical bone pressurized.It is newborn and creep to help callus.Promote the fracture healing acceleration.Biomechanics and Mechanics of Machinery fixation have been increased.
4, on the three rail synthetism steel plate central beam and the both sides arch ditch some screw holes are arranged, the reduction of the fracture of conciliation and fixation are all arranged, adapt to comminuted fracture especially.To comminuted fracture etc., anatomical reduction and biomechanics have been guaranteed, pathology and Mechanics of Machinery fixation.
5, use three rail synthetism steel plates, postoperative need not any external fixation, can prudent activity and walking, and life can be taken care of oneself.It is very painful to have removed instrument of torture worker formula extended immobilization.Alleviate financial burden, increased social benefit.
Below in conjunction with accompanying drawing specific embodiments of the present utility model is further described.
