Abstract
The invention discloses a limited contact inner-arc dynamic stress bone fracture plate. After the bone fracture plate is fixed on a fracture part, the distance between the bone fracture plate and the bone is 0.3 to 0.5 millimeter through an inner-arc structure on the limited contact inner-arc dynamic stress bone fracture plate; a periosteum is not peeled or subjected to pressure necrosis through a limited contact fixed mode so that the fracture end has good blood circulation and fracture healing is promoted; the stress generated by stressed deformation motion of the arc structure of the fixed section is transferred to the fracture end so that the healing of the fixed fracture bone can be accelerated through proper stress stimulation and the complication is reduced; and the bone fracture plate shortens the healing time and achieves biological fixation.
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, under the AO guide of theory, the blade plate that present orthopedic is used for the treatment of fracture mostly is strong pressurization internal fixation, union of fracture is of poor quality, complication is many, be because (1) 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 necrosis of supply fracture end blood fortune, made originally and suffered further destruction, thereby cause above complication and healing time to prolong even cause bone does not connect because of the blood fortune of the destructive fracture end of fracture; (2) stress shielding that causes of strong internal fixation makes fracture end lose the needed sinusoidal wave stress stimulation of osteogenesis, and common clinically delayed union even bone does not connect connect; Both made healing, the time also prolongs greatly, with the traditional therapy comparison time lengthening 30% of China.
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, to provide a kind of blood fortune that neither influences fracture end can avoid the limited contact inner-arc dynamic stress bone fracture plate of stress shielding again.
The technical scheme that the present invention solves the problems of the technologies described above employing is: be the stress bone fracture plate that adopts the fabulous titanium alloy of biocompatibility of low-elasticity-modulus amount, high antifatigue to make, it is characterized in that (1) is that arcuate structure is adopted at position between locking nail hole in the on-fixed section of blade plate, make steel plate except screw with surface of bone contacts, all the get along well surface of bone contact of other positions makes to have the distance of 0.3mm to 0.5mm between blade plate and the surface of bone.By limited contact contact 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.(2) the suitable position design stress at blade plate shifts shape, 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.(3) blade plate and screw adopt the fabulous titanium alloy manufacturing of biocompatibility of 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.
Description of drawings
Below in conjunction with drawings and Examples the present patent application is further specified.
Fig. 1 is that limited contact inner-arc dynamic stress bone fracture plate structure master looks sketch map.
Fig. 2 is a limited contact inner-arc dynamic stress bone fracture plate structure schematic top plan view.
Fig. 3 is that novel bone screw is looked sketch map to the master that limited contact inner-arc dynamic stress bone fracture plate is fixed on the bone.
To be novel bone screw be fixed to schematic top plan view on the bone to limited contact inner-arc dynamic stress bone fracture plate to Fig. 4.
Among the figure 1, the dynamic stress district, 2, dynamic stress adjustment district, 3, the gap between interior camber structure 4, locking nail hole 5, blade plate and periosteum (be about 0.3～0.5mm), 6, limited contact inner-arc dynamic stress bone fracture plate, 7, skeleton.
Concrete enforcement
The limited contact inner-arc dynamic stress bone fracture plate structure 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 limited contact inner-arc dynamic stress bone fracture plate structure is to be fixed on the position of fracture by novel bone screw, thereby it is fixed to reach noncontact.
Fig. 1, Fig. 2, Fig. 3, embodiment illustrated in fig. 4 in, be fixed in limited contact inner-arc dynamic stress bone fracture plate on the position of fracture by novel bone screw, marking 3 by interior camber structure such as Fig. 1 reaches limited contact fixed form and makes and have 0.3mm between blade plate and the skeleton and mark 5 to distance such as Fig. 3 of 0.5mm, make periosteum neither peel off and can not be oppressed necrosis, thereby make fracture end have good blood fortune, promote union of fracture.By among the stressed i.e. figure of canned paragraph arcuate structure the dynamic stress district, 1,2 place of marking and dynamic stress adjustment district distorted movement produce 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)
- Limited contact inner-arc dynamic stress bone fracture plate it is characterized in that on it (1) between the locking nail hole of blade plate, design in the camber structure, make steel plate except screw with surface of bone contacts, all the get along well surface of bone contact of other positions, make to have the distance of 0.3mm to 0.5mm between blade plate and the surface of bone, it is fixing to reach limited contact contact; (2) adopt dynamic stress bone fracture plate on-fixed section arc dynamic stress district and stress to adjust the plot structure distorted movement and make the shaft 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. camber structure, dynamic stress district, stress adjustment district, locking nail hole in according to claim 1 (1) limited contact inner-arc dynamic stress bone fracture plate which is provided with; (2) this blade plate feature, noncontact inner-arc dynamic stress bone fracture plate structure.
