Abstract
The invention relates to a proximal femur locking bone fracture plate. The proximal femur locking bone fracture plate comprises a top side surface, a bottom side surface used for being contact with a femur, and a group of through holes, wherein the top side surface is of an arc-shaped structure, at least one through hole is formed by the superposition parts of a pressing hole and a threaded hole, the pressing hole is a circular and thread-free, and an antibiotics layer is arranged on the inner side of the threaded hole. The proximal femur locking bone fracture plate provided by the invention has the advantages that the structure is simple, the safety is high, clinical demands are met, the bending strength of the bone fracture plate is high, when in use, locking screws can be screwed into quickly, the purpose of connecting bones more firmly is realized, in addition, the antibiotics layer covers on the inner wall of the threaded hole, a stronger antibacterial effect is realized, and the healing of fracture bones is accelerated.
Description
Technical field
The invention belongs to a kind of orthopedic medical device, be specifically related to a kind of near end of thighbone locking bone fracture plate.
Background technology
Micro wound coaptation plate osteopathy is a kind of technology of modern fracture fixation, it adopts indirectly reduction of the fracture technology, and fixedly maintain fracture reduction with the steel plate without pressurization, surgical exposure and soft tissue extent of exfoliation have been reached to be minimized, can improve union of fracture rate, and reduce the incidence rate of complication.But existing blade plate mounting screw time that need to be longer and easily loosening, in addition, the antibiotics concentration of existing hone lamella is low, and effective treatment cannot be provided, and therefore, for the problem of above-mentioned appearance, just needs a kind of technical scheme of solution.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of near end of thighbone locking bone fracture plate, to overcome the deficiency of existing steel plate structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of near end of thighbone locking bone fracture plate is provided, described blade plate has a top side face, for contacting bottom side and one group of through hole of bone, described top side face is arcuate structure, serve as reasons pressurization hole and the overlapping composition of screwed hole part of at least one through hole wherein, pressurization hole is circular without screw thread, and described screwed hole inner side is provided with antibiotic layer.
Preferably, on described blade plate, be provided with locating hole.
Preferably, attenuation and head end are arc gradually at the two ends of described blade plate.
Preferably, described screwed hole is inverted cone.
Preferably, the thickness of described antibiotic layer is 0.5mm～0.8mm.
Preferably, the thickness of described antibiotic layer is 0.6mm.
Preferably, described blade plate is made by pure titanium material.
Preferably, described blade plate is made by stainless steel material.
Near end of thighbone locking bone fracture plate provided by the invention is simple in structure, safe, be applicable to clinical demand, blade plate bending strength is high, can make in use lock screw be screwed into fast, can reach the object that connects more firmly bone, in addition, on the inwall of screwed hole, cover antibiotic layer, can possess stronger antibiotic property and bone is cured faster.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 be near end of thighbone locking bone fracture plate of the present invention structural representation.
Number in the figure is described as follows:
10, blade plate; 20, top side face; 30, bottom side; 40, through hole; 50, pressurization hole; 60, screwed hole; 70, antibiotic layer; 80, locating hole.
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.Those skilled in the art can understand other advantages of the present invention and effect easily by the disclosed content of this description.The present invention can also be implemented or be applied by the other different specific embodiment, and the every details in this description also can be based on different viewpoints and application, carries out various modifications or change not deviating under spirit of the present invention.
As shown in Figure 1, a kind of near end of thighbone locking bone fracture plate is provided, described blade plate 10 has a top side face 20, for contacting bottom side 30 and one group of through hole 40 of bone, described top side face 20 is arcuate structure, serve as reasons pressurization hole 50 and the overlapping composition of screwed hole 60 part of at least one through hole 40 wherein, pressurization hole 50 is circular without screw thread, and described screwed hole 60 inner sides are provided with antibiotic layer.
In the present embodiment, the two ends of described blade plate 10 gradually attenuation and head end are arc, with the bone profile of fitting, and better fixing bone, preferred, described screwed hole 60 is inverted cone, and screw is also taper, strengthens coordinating of screw and screwed hole, and bending strength is high.
In addition, the thickness of described antibiotic layer 70 is 0.5mm～0.8mm.Preferably, the thickness of described antibiotic layer 70 is 0.6mm.Described blade plate 10 is made by pure titanium material or rustless steel.
Preferably, on described blade plate 10, be provided with locating hole 80, when synthetism, locating hole 80 plays auxiliary positioning effect.
Near end of thighbone locking bone fracture plate provided by the invention is simple in structure, safe, be applicable to clinical demand, blade plate bending strength is high, can make in use lock screw be screwed into fast, can reach the object that connects more firmly bone, in addition, on the inwall of screwed hole, cover antibiotic layer, can possess stronger antibiotic property and bone is cured faster.
Above-mentioned explanation illustrates and has described some preferred embodiments of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in invention contemplated scope described herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from the spirit and scope of the present invention, all should be in the protection domain of claims of the present invention.
