Abstract
The invention provides an internal fixing support system capable of eliminating rotation stress. The internal fixing support system is characterized by being formed by a main body structure, locking holes, locking pressurizing holes and a dynamic stress zone. The main body structure is a shuttle-shaped strip alloy plate, the middle section part of the main body structure is widened to form symmetrical arc-shaped protrusions which form a rotation stress adjustment zone, and four small holes are distributed around the rotation stress adjustment zone. The locking holes and the locking pressurizing holes are evenly distributed on the two sides of the alloy plate of the main body structure outside the rotation stress adjustment zone. A concave-downward arc is formed on the main body structure close to the surface of the skeleton in the rotation stress adjustment zone, the concave-downward length is 0.3mm-0.5mm, and the concave-downward arc serves as the dynamic stress zone.
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, orthopedic is used to treat the blade plate of fracture at present, and its structure is many to be main with strong pressurization internal fixation, and union of fracture is of poor quality, and complication is many; Especially when fracture come across the position that can produce big rotation stress (as femoral shaft, humerus do, the chi radius is done etc.); Because factors such as fracture back myotasis cause fracture site to produce rotation stress; Steel plate after fixing can produce slippage; Thereby the healing of influence fracture, even fracture delayed union or disunion occur, the situation that steel plate fractures under the healing state not of fracturing is also very common.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of blood fortune that neither influences fracture end, can effectively offset the elimination rotation stress inner fixed support system of rotation stress again.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of elimination rotation stress inner fixed support system is characterized in that this system is made up of agent structure, lock hole, locking pressurization hole and dynamic stress district; Agent structure is the strip alloy sheets of fusiformis, and its stage casing part is widened and formed symmetric arc convex, is rotation stress adjustment district, and the rotation stress adjustment is distributed with four apertures around the district, is used to pass wire rope binding bone piece; Lock hole, locking pressurization hole are uniformly distributed in the both sides alloy sheets of agent structure except that rotation stress adjustment district; One side in rotation stress adjustment district near skeleton, agent structure presents a recessed arc, and its recessed height is 0.3mm-0.5mm, is the dynamic stress district.
The locking nail end gets into bone by lock hole, and pressurization synthetism nail is terminal to get into bone by locking pressurization hole, and the inner fixed support system is firmly contacted with bone.
Said lock hole can be selected voluntarily based on the knochenbruch situation with locking pressurization hole number.
This system uses the biocompatibility alloy manufacturing preferably of low-elasticity-modulus amount, high antifatigue.
The present invention through locking nail and pressurization synthetism nail with after skeleton is connected; Stress and deformation through rotation stress adjustment district; Offset the rotation stress that fracture end produces, make after the fracture fixation skeleton both can through suitable stress stimulation healing acceleration with reduce complication, the shortening healing time; Reach and fix biology, can reduce the adverse effect of rotation stress again fracture end; And the setting in dynamic stress district both can guarantee firmly to be connected with skeleton the present invention through bone screw, was suspended on surface of bone again at fracture; This noncontact fixed form; Make periosteum neither peel off and can not be oppressed necrosis, thereby guarantee the blood fortune that fracture end is good, promote union of fracture; The present invention is particularly useful for the bigger fracture segment of rotation stress, and for example femoral shaft, humerus are done, the chi radius is done etc., and it can reduce the harm of rotation stress to union of fracture, can promote union of fracture again.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Embodiment 1, a kind of elimination rotation stress inner fixed support system, and with reference to Fig. 1, shown in Figure 2, this system is made up of agent structure 5, lock hole 2, locking pressurization hole 4 and dynamic stress district 1; Agent structure 5 is the strip alloy sheets of fusiformis, and its stage casing part is widened and formed symmetric arc convex, is rotation stress adjustment district 3, is distributed with four apertures around the rotation stress adjustment district 3, is used to pass wire rope 9 binding bone pieces; Seven lock holes 2, a locking pressurization hole 4 are uniformly distributed in the both sides alloy sheets of agent structure 5 except that rotation stress adjustment district; 3 the one sides in rotation stress adjustment district near skeleton, agent structure presents a recessed arc, and its recessed height is 0.3mm-0.5mm, is dynamic stress district 1.
In use; Like Fig. 3, shown in Figure 4, utilize the locking nail 7 and the synthetism nail 8 that pressurizes that the present invention is fixed on the different parts that backbone 6 fractures, the stress and deformation motion counteracting fracture end of distinguishing through the rotation stress adjustment rotates the stress that produces; Make skeleton after the fracture fixation both can be through suitable stress stimulation healing acceleration and minimizing complication; Shorten healing time, reach and fix biology, can reduce the adverse effect of rotation stress again fracture end; The present invention is connected and fixed on the skeleton through novel bone screw; The distance that has 0.3mm-0.5mm between dynamic stress district and the knochenbruch skeleton through the noncontact fixed form, makes periosteum neither peel off and can not be oppressed necrosis; Thereby make fracture end have good blood fortune, promote union of fracture.
