Abstract
The dynamic stress valve type dynamic stress bone-knitting steel plate is provided with a locking nail hole, a pressurizing and locking nail hole, a dynamic stress valve and a dynamic control shaft, and is characterized in that (1) the dynamic stress valve structure is designed to deform and move at the middle part of the bone-knitting plate to generate stress at the fracture part, so that the bone after fracture fixation can be accelerated to heal and complications can be reduced through 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 stress valve type 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: adopt the dynamic stress valve arrangement in synthetism steel plate middle part, this structure produces deformation with the motion of limbs makes fracture produce stress.The stress valve type 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, pressurization, locking nail hole, dynamic stress valve, dynamically Control Shaft.It is characterized in that (1) adopt dynamic stress valve type dynamic stress synthetism steel plate, utilize the dynamic stress valve 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 stress valve type dynamic stress steel plate structure master looks sketch map.
Fig. 2 is a stress valve type dynamic stress steel plate structure schematic top plan view.
Among the figure 1, the locking nail hole; 2, pressurization, locking nail hole; 3, dynamic stress valve; 4, dynamic Control Shaft.
Concrete enforcement
Dynamic stress valve type dynamic stress synthetism steel plate is fixed on the different parts of fracture, makes fracture end produce stress by the dynamic stress valve distorted movement; The stress steel plate is to be fixed on the position of fracture by novel bone screw.
Fig. 1, embodiment illustrated in fig. 2 in, dynamic stress valve type dynamic stress synthetism steel plate is fixed on key fracture site, make fracture end produce stress by the dynamic stress valve distorted movement; 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, dynamic stress valve type dynamic stress synthetism steel plate which is provided with the locking nail hole, pressurization, locking nail hole, dynamic stress valve, dynamic Control Shaft, it is characterized in that (1) adopt the dynamic stress valve arrangement in synthetism steel plate middle part, this structure produces deformation with the motion of limbs makes fracture produce stress.
