Abstract
The invention provides a continuous stress internal fixing bracket system. The continuous stress internal fixing bracket system is characterized by comprising a main body structure, conical locking holes, locking pressurizing holes and an arc groove structure stress area, wherein the main body structure is a fusiform strip alloy plate of which two ends are narrower than the middle; the conical locking holes and the locking pressurizing holes are uniformly distributed on the alloy plate on two sides except an intermediate area of the main body structure; a plurality of downwards-concaved arcs are distributed on one surface, which is close to a skeleton, of the main body structure in the intermediate area, and between the conical locking holes and the locking pressurizing holes; the height of each downward concave is 0.3-0.5mm; and the downward concave parts form the arc groove structure stress area.
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
Under AO (international internal fixation association) guide of theory; At present mostly the orthopedic blade plate that is used to treat fracture is strong pressurization internal fixation pattern; Union of fracture is of poor quality, complication is many, and its reason is: (1) steel plate internal fixation is to adopt steel plate to fix the stress shielding of generation through the press fit generation frictional force that adds of screw; Make fracture end lose the needed sinusoidal wave stress stimulation of osteogenesis; Common clinically delayed union even bone does not connect connect, even healing, the time also prolongs greatly; (2) present blade plate is strong pressurization internal fixation 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; Made originally and suffered further destruction, thereby cause complication and healing time to prolong because of the blood fortune of the destructive fracture end of fracture.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the present invention provides a kind of blood fortune that neither influences fracture end can avoid the continuous stress inner fixed support system of stress shielding again.
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 up of agent structure, taper lock hole, locking pressurization 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 pressurization hole are uniformly distributed in agent structure and remove on the both sides alloy sheets in zone, middle part; Between central region and taper lock hole, locking pressurization each hole, 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.
Through the taper lock hole, locking synthetism nail end utilizes lock screw that the inner fixed support system is fixed on the skeleton; Pressurization synthetism nail gets into skeleton through locking pressurization hole, and the inner fixed support system firmly is connected with skeleton.
This system uses the biocompatibility alloy manufacturing preferably 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 that the synthetism nail with surface of bone contacts, other positions are suspended on bone surface, and have the distance of 0.3mm-0.5mm between the bone surface; Through 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 pressurization hole on the rack body; Rack body becomes the mounting system framework with fixed fractured bones form, and it is unsettled at bone surface, through successive flute profile arc structure; Can be the full sections of Stress Transfer to fracture end and frame fixation; 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; The fabulous alloy manufacturing of biocompatibility of rack body and locking synthetism nail employing low elastic modulus, high antifatigue; Has better elastic; 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
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Embodiment 1, and a kind of continuous stress inner fixed support system with reference to Fig. 1, shown in Figure 2, is made up of agent structure 4, two taper lock holes 2, six locking pressurization 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 pressurization hole 3 are uniformly distributed in agent structure and remove on the both sides alloy sheets in zone, middle part; Between central region and taper lock hole, locking pressurization each hole, 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; Like Fig. 3, shown in Figure 4; By taper lock hole and locking pressurization hole; The locking synthetism is followed closely 6 ends and is utilized 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 maintenance of deep-slotted chip breaker structure and the bone 5; Constitute 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; Stress and deformation motion by the deep-slotted chip breaker structure produces stress transfer to fracture end; Make bone after the fracture fixation still can be by suitable stress stimulation healing acceleration and minimizing complication, shorten healing time, framework institute fixed-segment reduces; Eliminate osteoporotic generation, reach biology and fix.
