Abstract
An Inner-arc diaphysis-type dynamic-stress bone-fracture fixation steel plate comprises locking nail holes, a regulating and locking nail hole and a dynamic stress area, and is characterized in that an appropriate part of the bone-fracture fixation plate is designed into a stress-transfer shape, and stress can be generated at the fracture end of diaphysis by the deformation movement of the arc structure of a unfixed part of the dynamic stress bone fracture plate, so as to accelerate the healing process and reduce the complications of bones after the fracture fixing through appropriate stress stimulation, and to shorten the healing process and achieve the biological osteosynthesis; and the bone fracture is fixed through non-contact or limited-contact methods without the periosteal stripping, so as to realize good blood circulation of the fracture end and promote the fracture healing.
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 key type dynamic stress of safe and reliable inner arc 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: adopt dynamic stress bone fracture plate on-fixed section arcuate structure in the dynamic stress district, this structure produces deformation with the motion of limbs makes fracture produce stress stimulation.The dynamic stress synthetism steel plate that the fabulous titanium alloy of biocompatibility of employing low-elasticity-modulus amount, high antifatigue is made which is provided with the locking nail hole, adjusts 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 is that the key type dynamic stress of inner arc steel plate structure master looks sketch map.
Fig. 2 is the key type dynamic stress of an inner arc steel plate structure schematic top plan view.
Among the figure 1, the locking nail hole, 2, adjust the locking nail hole, 3, the dynamic stress district.
Concrete enforcement
The key type dynamic stress of inner arc steel plate is fixed on the different parts of shaft fracture, and the stress and deformation motion by the canned paragraph arcuate structure produces stress transfer to fracture end; The key type dynamic stress of inner arc steel plate is to be fixed on the position of fracture by novel bone screw.
Fig. 1, embodiment illustrated in fig. 2 in, the key type dynamic stress of inner arc synthetism steel plate is fixed on key fracture site, 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 (1)
1, the key type dynamic stress of inner arc synthetism steel plate which is provided with the locking nail hole, adjusts locking nail hole, dynamic stress district, it is characterized in that (1) adopt dynamic stress bone fracture plate on-fixed section arcuate structure in the dynamic stress district, this structure produces deformation with the motion of limbs makes fracture produce stress stimulation.
