Abstract
The bone end arc dynamic stress bone-knitting steel plate is provided with a locking nail hole, an adjusting locking nail hole and a dynamic stress area, and is characterized in that (1) a stress transfer shape is designed at a proper position of the bone fracture plate, and the stress is generated at the fracture part of the bone end by adopting the arc-shaped structure deformation motion of the non-fixed section of the dynamic stress bone fracture plate, so that the bone after fracture fixation can be accelerated to heal and complications can be reduced by proper stress stimulation; the healing time is shortened, and biological fixation is achieved; (2) the fracture of the bone end is fixed in a non-contact or limited contact fixing mode, periosteum is not peeled off, the fracture end has good blood circulation, and fracture healing is promoted.
Description
Technical field
The invention belongs to the orthopedic field of clinical medicine Orthopeadic Surgery, be used to fracture and orthopedic fixing and promotion union of fracture.
Background technology
We know that orthopedic mostly is strong pressurization internal fixation with blade plate at present, and union of fracture is of poor quality, complication is many; Be because present blade plate is in fracture or tries hard to complete replacement bone ilium when orthopedic and implement function, thereby cause above complication and healing time to prolong.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned the deficiencies in the prior art, a kind of safe and reliable epiphysis camber dynamic stress synthetism steel plate of guaranteeing to be provided.
The technical scheme that the present invention solves the problems of the technologies described above employing is: be the dynamic stress synthetism steel plate that adopts the fabulous titanium alloy of biocompatibility of low-elasticity-modulus amount, high antifatigue to make, which is provided with the locking nail hole, adjust locking nail hole, dynamic stress district.It is characterized in that (1) suitable position design stress transfer shape at blade plate, adopt dynamic stress bone fracture plate on-fixed section arcuate structure distorted movement to make fracture end produce stress, make skeleton after the fracture fixation still can be by suitable stress stimulation healing acceleration and minimizing complication; Shorten healing time, reach and fix biology.(2) adopt the fabulous titanium alloy manufacturing of biocompatibility of low elastic modulus, high antifatigue, interior for the low elastic modulus beta titanium alloy has better elastic and high antifatigue, the favorable tissue compatibility, and harmless.The low elastic modulus titanium alloy has better elastic, can in muscle contraction or when motion produce elastic deformation and make fracture have corresponding motion to produce stress, and stimulate union of fracture to accelerate.(3) by noncontact or limited contact fixed form with fracture fixation, periosteum is not peeled off, and makes fracture end have good blood fortune, promotes union of fracture.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 epiphysis curved plate structure master looks sketch map
Fig. 2 epiphysis curved plate structure schematic top plan view
Among the figure 1, locking nail hole 2, adjust locking nail hole 3, dynamic stress district 4, epiphysis district.
Concrete enforcement
Epiphysis camber dynamic stress bone fracture plate is fixed on the different parts of bone fracture, and the stress and deformation motion by the canned paragraph arcuate structure produces stress transfer to fracture end; Epiphysis camber dynamic stress bone fracture plate is to be fixed on the position of fracture by novel bone screw.
Fig. 1, embodiment illustrated in fig. 2 in, epiphysis camber dynamic stress synthetism steel plate is fixed on the fracture site of epiphysis, the stress and deformation motion by the canned paragraph arcuate structure produces stress transfer to fracture end; Make skeleton after the fracture fixation still can be by suitable stress stimulation healing acceleration and minimizing complication; Shorten healing time, reach and fix biology.
Claims (2)
1, epiphysis camber dynamic stress synthetism steel plate which is provided with the locking nail hole, adjusts locking nail hole, dynamic stress district, it is characterized in that shifting shape, adopt dynamic stress bone fracture plate on-fixed section arcuate structure distorted movement to make the bone fracture place produce stress at an end design stress of blade plate.
2, epiphysis camber dynamic stress synthetism steel plate according to claim 1 is characterized by epiphysis camber steel plate structure.
