Abstract
The invention discloses a high-reliability bone plate set, belongs to the technical field of medical equipment, and aims to solve the problem that the middle of a traditional bridge type bone plate set is easily broken. The technical scheme includes that the high-reliability bone plate set comprises a strip plate body, a plurality of screw holes uniformly distributed along the length direction are formed in the strip plate body, after improvement, the thickness of the middle of the strip plate body is maximum, and the thickness of the strip plate body is gradually decreased from the middle to two ends of the strip plate body. By the aid of a variable cross-section structure, the mechanical strength of the strip plate body is enhanced by increasing the cross-sectional area of the middle of the strip plate body, stress applied to all positions of the strip plate body in unit cross-sectional area is consistent, so that breakage of the bone plate set is effectively prevented, and the treatment effect of fracture is ensured.
Description
Technical field
The present invention relates to a kind of blade plate that uses when fracturing for the treatment of, belong to the medical devices technical field.
Background technology
Blade plate is one of main internal fixation device for the treatment of limb long tubular bone ilium folding.The tradition blade plate generally all is the uniform stripe board of thickness and width, length direction along blade plate is evenly equipped with a plurality of screw holes, during the treatment fracture, the middle part of blade plate leans against the fracture of elongated tubular skeleton, two ends by screw respectively with the skeletal fixation of fracture both sides together, reach the purpose of reinforcing affected bone.Because the suffered Stress non-homogeneity of blade plate, two ends stress is less, and it is larger with the suffered stress in corresponding middle part of fracturing, therefore be prone to the phenomenon that screw and blade plate become flexible, rupture in the use procedure in the middle part of the plate body, when especially treating Fracture of femur, blade plate middle part usually stress is excessive and rupture, and causes treating unsuccessfully, causes larger misery and financial burden to the patient.Therefore but be necessary to design a kind of dispersive stress, the blade plate of easy fracture not, in order to reinforce more reliably affected bone, guarantee the therapeutic effect of fracture.
Summary of the invention
The object of the invention is to the drawback for prior art, a kind of blade plate of high reliability is provided, with reliable fixedly affected bone, guarantee the therapeutic effect of fracture.
Problem of the present invention realizes with following technical proposals:
A kind of blade plate of high reliability comprises the strip plate body in the formation, be provided with a plurality ofly along the uniform screw hole of its length direction on the described strip plate body, and after the improvement, the interior thickness of strip plate body is maximum, and from the centre to two ends, the thickness of strip plate body diminishes gradually.
It is flat bullet shape that the blade plate of above-mentioned high reliability, described strip plate body have an end at least.
The blade plate of above-mentioned high reliability, the width of described strip plate body interlude is greater than the width at other position.
The blade plate of above-mentioned high reliability, the contour line of described strip plate body interlude both sides are symmetrical wave, and in the interlude of strip plate body, the width at screw hole place is greater than the width at other position.
The present invention adopts variable section structure, increase its mechanical strength by the cross-sectional area that increases strip plate body middle part, make the stress that unit cross-sectional area bears on each position of strip plate body basically identical, thereby effectively prevented the generation of blade plate phenomenon of rupture, guaranteed the therapeutic effect of fracture.

The specific embodiment
The thickest in the middle of the present invention, two ends are attenuation gradually, and when using the crackled skeleton of blade plate reinforce belt, the thickest middle partial fixing is in the slight crack place of skeleton, and the stress that bear in this place is maximum; And less from the two-end thickness of skeleton slight crack away from, the stress that bears is also less.The stress that this structure can make the plate body unit cross-sectional area of blade plate different parts bear approaches, and helps to improve the whole steadiness of plate body.Can further reduce the stress that blade plate middle part unit cross-sectional area bears by increasing the width at strip plate body middle part in addition, thereby improve the bulk strength of blade plate.
Referring to Fig. 1, the blade plate two ends can all be designed to the bullet shape that flattens, and there is the function of periosteal elevator at two ends like this, are convenient to insert under the muscle.There are three kinds of structures at the middle part of this blade plate: the first is that the middle part is not widened, and only improves middle part intensity by increasing thickness, and its top view as shown in Figure 3; The second is that the middle part is widened, and the contour line of widened section both sides is camber line, and its top view as shown in Figure 4; The third is that the middle part is widened, and the contour line of widened section both sides is symmetrical wave, and its top view as shown in Figure 5.When contour line was symmetrical wave, the widest position of strip plate body was corresponding with screw hole.
Referring to Fig. 6, the bullet shape that blade plate only has an end to be designed to flatten, the thickness of bullet shape one end can be 1/6～1/2 of traditional blade plate thickness, the thickness of the other end can be 1/3～2/3 of traditional blade plate thickness, the middle part of this blade plate has three kinds of structures equally: the first is that the middle part is not widened, only improve middle part intensity by increasing thickness, its top view as shown in Figure 7; The second is that the middle part is widened, and the contour line of widened section both sides is camber line, and its top view as shown in Figure 8; The third is that the middle part is widened, and the contour line of widened section both sides is symmetrical wave, and its top view as shown in Figure 9.
Certainly, even the blade plate two ends are not bullet shapes all, as long as satisfy thick middle, two ends are attenuation gradually, all will fall into the protection domain of this patent.
