Abstract
The utility model provides a continuous type stress internal fixation support frame system. The continuous type stress internal fixation support frame system is characterized by comprising a main body structure, cone-shaped locking holes, locking pressurizing holes and arc-shaped groove structure stress zones, wherein two ends of the main body structure are narrower than a fusiform strip-shaped alloy plate in the middle of the main body structure, the cone-shaped locking holes and the locking pressurizing holes are evenly distributed in alloy plates which are located on two sides of the main body structure except the alloy plate in the middle of the main body structure, multiple downward concave arc-shaped portions are distributed in the middle of the main body structure and between the cone-shaped locking holes and the locking pressurizing holes in the side, close to a skeleton, of the main body structure, the height of each downward concave arc-shaped portion is 0.3 millimeter to 0.5 millimeter, and the multiple downward concave arc-shaped portions are the arc-shaped groove structure stress zones.
Description
Technical field
The invention belongs to the orthopedic field of clinical medicine Orthopeadic Surgery, be specifically related to a kind of inner fixed support system.
Background technology
Fixing association in the AO(world) under the theoretical guidance, the blade plate that present orthopedic is used for the treatment of fracture mostly is fixed model in the strong pressurization, healing of fracture is poor, complication is many, its reason is: fixedly be to adopt steel plate to fix by the fixing frictional force that produces of the pressurization of screw in (1) steel plate, the stress shielding that produces, make fracture end lose the needed sinusoidal wave stress stimulation of osteogenesis, clinically common delayed union even Bone nonunion, even healing, the time also prolongs greatly; (2) present blade plate is fixing in the strong pressurization when treatment is fractured or be orthopedic, be close on the surface of skeleton, cause the periosteum pressurized of supply fracture end blood fortune downright bad, make originally the blood fortune of the fracture end that destroys because of fracture suffer further destruction, thereby cause complication and healing time to prolong.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the continuous stress inner fixed support system that a kind of blood fortune that neither affects fracture end can be avoided again stress shielding.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of continuous stress inner fixed support system is characterized in that this system is made of agent structure, taper lock hole, locking compress hole and arcuate groove structural stress district; Agent structure is the fusiformis strip alloy sheets that two ends are narrower than the middle part, and taper lock hole, locking compress hole are uniformly distributed in agent structure except on the both sides alloy sheets in zone, middle part; Between central region and taper lock hole, each hole, locking compress hole, agent structure is distributed with a plurality of recessed arcs in the one side near skeleton, and recessed height is 0.3mm-0.5mm, is arcuate groove structural stress district.
By the taper lock hole, locking bone nail end utilizes lock screw that the inner fixed support system is fixed on the skeleton; The pressure bone setting nail enters skeleton by the locking compress hole, and the inner fixed support system firmly is connected with skeleton.
This system uses the preferably alloy manufacturing of biocompatibility of low-elasticity-modulus amount, high antifatigue.
The present invention adopts the arcuate groove structure at the position of respectively following closely between the hole of rack body, make alloy sheets except bone nail with surface of bone contacts, other positions are suspended on bone surface, and the distance that has 0.3mm-0.5mm between the bone surface, by the noncontact fixed form, make periosteum neither peel off and can not be oppressed necrosis, thereby make fracture end have good blood fortune, promote union of fracture; Be designed with taper lock hole and locking compress hole on the rack body, rack body becomes the mounting system framework with the fractured bones form of fixing, it is unsettled at bone surface, by continuous flute profile arc structure, can be Stress Transfer to fracture end and the fixing full sections of framework, therefore along with the variation of stress, fracture end all has stress stimulation with fixing full sections, but accelerating bone healing and prevention fixed-segment osteoporosis; Rack body and locking bone nail adopt the fabulous alloy manufacturing of biocompatibility of low elastic modulus, high antifatigue, has good elasticity, can when muscle contraction or motion, produce elastic deformation, and make fracture have corresponding motion to produce sinusoidal wave stress, stimulate union of fracture to accelerate.

The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Embodiment 1, and a kind of continuous stress inner fixed support system with reference to Fig. 1, shown in Figure 2, is made of agent structure 4, two taper lock holes 2, six locking compress holes 3 and seven arcuate groove structural stress districts 1; Agent structure 4 is narrower than the fusiformis strip alloy sheets at middle part for two ends, and taper lock hole 2, locking compress hole 3 are uniformly distributed in agent structure except on the both sides alloy sheets in zone, middle part; Between central region and taper lock hole, each hole, locking compress hole, agent structure is distributed with seven recessed arcs in the one side near skeleton, and recessed height is 0.3mm-0.5mm, is arcuate groove structural stress district 1.
In use, as shown in Figure 3, Figure 4, by taper lock hole and locking compress hole, locking bone nail 6 ends utilize lock screw that mounting system is fixed on the fracture site, and mounting system makes and self is suspended on bone surface by the distance of 0.3mm-0.5mm between the maintenance of arcuate groove structure and the skeleton 5, consist of the noncontact fixed frame, make periosteum neither peel off and can not be oppressed necrosis, thereby keep the good blood fortune of fracture end, promote union of fracture; Stress and deformation motion by the arcuate groove structure produces stress transfer to fracture end, make the skeleton after the fracture fixation still can be by suitable stress stimulation and healing acceleration and complication shorten healing time, framework institute fixed-segment reduces, eliminate osteoporotic generation, reach and fix biology.
