Abstract
The invention discloses a non-contact inner arc diaphysis-shaped stress bone fracture plate. The bone fracture plate is fixed on a fracture position by a novel bone screw to cause the distance between a steel plate and the bone to be 0.3mm-0.5mm, and periosteum is not stripped off and can not be damaged due to compression by non-contact fixation, thus causing a fracture end to have good blood circulation and promoting the fracture to heal; stress is produced by stress deformation motion of arc structure at a fixed section and then transferred to the fracture end; the fixed bone due to the fracture can still quickly heal and complication are reduced by proper stress stimulation; and healing time is shortened, and biological fixation is achieved.
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 non-contact inner arc diaphysis-shaped 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, 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) 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.(3) screw is made lock-out state, make reducing-pitch thread, make blade plate fixed, but the contact of discord surface of bone makes to have the distance of 0.3mm to 0.5mm between blade plate and the skeleton in nail tail and the part that enters bone.By the noncontact 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.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is that non-contact inner arc diaphysis-shaped stress bone fracture plate structure master looks sketch map.
Fig. 2 is a non-contact inner arc diaphysis-shaped stress bone fracture plate structure schematic top plan view.
Fig. 3 is that novel bone screw is looked sketch map to the master that non-contact inner arc diaphysis-shaped 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 non-contact inner arc diaphysis-shaped stress bone fracture plate to Fig. 4.
Among the figure 1, the locking nail hole, 2, adjust the locking nail hole, 3, the gap between dynamic stress district 4, blade plate and periosteum (is about 0.3～0.5mm).
Concrete enforcement
The non-contact inner arc diaphysis-shaped 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 non-contact inner arc diaphysis-shaped 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, embodiment illustrated in fig. 2 in, be fixed in non-contact inner arc diaphysis-shaped stress bone fracture plate on the position of fracture by novel bone screw, shown in Fig. 3,4, make and have the distance of 0.3mm between blade plate and the skeleton to 0.5mm, by the noncontact 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.Produce stress transfer to fracture end by marking 3 place dynamic stress district distorted movement among the stressed i.e. figure of canned paragraph arcuate structure; 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, non-contact inner arc diaphysis-shaped stress bone fracture plate 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 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) reducing-pitch thread by novel bone screw reaches the noncontact fixed form with fracture fixation, and periosteum is not peeled off not pressurized, makes fracture end have good blood fortune, promotes union of fracture.
2, according to claim 1 (1) non-contact inner arc diaphysis-shaped stress bone fracture plate which is provided with the locking nail hole, adjusts locking nail hole, dynamic stress district; (2) this blade plate feature, the key type blade plate of inner arc structure; (3) reducing-pitch thread by novel bone screw reaches noncontact and fixes.
