Abstract
The utility model relates to the medical equipment field, specifically, an inner bone fixer to connect broken bones, which is a connected-bone inner fixer, which is made of a compound material of hydroxyapatite /zirconium dioxide bioceramic, comprising a fixing panel (1) and screws (2). The fixing panel (1), at least, provides 4 screw holes (3). Back of the fixing panel (1) appears in an arc face matched with the bone. The compound material of hydroxyapatite /zirconium dioxide bioceramic is made into the connected-bone inner fixer, so as to increase strength, toughness and bone biocompatibility of the connected-bone inner fixer, meanwhile, which will not create poisonous or side effects to human body. After the patient's broken-bone healing, no removal surgery is necessary any more. Meanwhile, only the fixing panel and the screws are used for the knitting, structure of which is simple and reasonable.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of inner bone fixer that connects knochenbruch.
Background technology
The existing inner fixer that is used to connect knochenbruch is generally all made by metal material, relatively poor with the amalgamation of bone, generally be earlier the metal inside-fixture to be placed the knochenbruch place, after the healing, by performing the operation, make the patient bear misery inevitably twice so again with taking-ups such as steel plate, screws.Though disclosing the patent No. in China on November 23rd, 2005 is 200510050345.9, publication number is CN1699270A, name is called the patent of invention of preparation method of a kind of hydroxyapatite/zirconium dioxide biological ceramic composite material and products thereof, the compound bioceramic material that obtains of this composite material by adopting hydroxyapatite and zirconium dioxide, the inorganic mineral structural similarity of the structure of hydroxyapatite and human body bone, itself and zirconium dioxide compound, its intensity and toughness have been strengthened, can obviously promote osteoblastic increment and differentiation, energy and bone fuse, have better biocompatibility and have immune compatibility preferably, but this material is not applied on the synthetism inner fixer.And the parts that the general synthetism inner fixer that uses is adopted are also more relatively, and planform is relatively complicated, and how above-mentioned hydroxyapatite/zirconium dioxide biological ceramic composite material being applied in the synthetism holder is the problem that presses for solution.
Summary of the invention
Goal of the invention of the present utility model is to make with hydroxyapatite/zirconium dioxide biological ceramic composite material, provides a kind of amalgamation better, simple and reasonable synthetism inner fixer.
Of the present utility model solving the problems of the technologies described above by following technical proposals solved: a kind of synthetism inner fixer, make by hydroxyapatite/zirconium dioxide biological ceramic composite material, form by fixing head and screw, at least be provided with 4 screws on the described fixing head, the back side of fixing head is the cambered surface that cooperates with bone photo.
Screw on the said fixing plate is a mounting hole, and the one lateral edges is provided with head of screw half counterbore.
Above-mentioned screw is a tapping screw.
Adopt the utility model of the technical program, its beneficial effect is, hydroxyapatite/zirconium dioxide biological ceramic composite material is applied in the synthetism inner fixer, increased the synthetism inner fixer intensity, toughness and with the biocompatibility of bone, and human body do not produced toxic and side effects, the patient need not do once more and extract operation after the knochenbruch healing.Simultaneously this utility model only adopts combining of fixing head and screw, and is simple and reasonable for structure.

Fig. 1 is the perspective view of fixing head in the present embodiment.
Fig. 2 is the perspective view of screw in the present embodiment.
Fig. 3 is the three-dimensional sketch map of fixing head and screw in the present embodiment.
Fig. 4 is the front view of fixing head in the present embodiment.
Fig. 5 is the rearview of fixing head in the present embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:
Shown in Fig. 1,2,3,4,5, a kind of synthetism inner fixer, make by hydroxyapatite/zirconium dioxide biological ceramic composite material, this kind material increased the synthetism inner fixer intensity, toughness and with the compatibility of bone, the patient is after the knochenbruch healing, need not do once more and extract operation, this inner fixer is along with the healing of knochenbruch is directly merged mutually with bone.
This inner fixer is made up of fixing head 1 and screw 2, described screw 2 is a tapping screw, make the interior back of screw precession bone be difficult for withdrawing from voluntarily, the back side of described fixing head 1 is the cambered surface that cooperates with bone photo, evenly be provided with 6 screws 3 on the fixing head 1 along its length, screw 3 is a mounting hole, and be positioned at fixing head 1 front towards the waist shape edge on one side of screw 3 on be provided with head of screw counterbore 31, the direction of head of screw half counterbore 31 on 3 screws 3 in left side just in time with 3 screws 3 in right side on the direction symmetry of head of screw counterbore 31, like this when 6 screws 2 are not provided with head of screw counterbore 31 from screw 3 one side enters bone, slowly be spun on the one side that is provided with head of screw half counterbore 31, make 2 knochenbruch can try one's best, help the bone quickly-healing toward middle extruding.
Claims (3)
1. synthetism inner fixer, make by hydroxyapatite/zirconium dioxide biological ceramic composite material, it is characterized in that being made up of fixing head (1) and screw (2), be provided with 4 screws (3) on the described fixing head (1) at least, the back side of fixing head (1) is the cambered surface that cooperates with bone photo.
2. a kind of synthetism inner fixer according to claim 1, the screw (3) that it is characterized in that being positioned on the fixing head (1) is a mounting hole, the one lateral edges is provided with head of screw half counterbore (31).
