Abstract
The invention relates to the technical field of medical instruments, in particular to an acetabular bone file with a rotating shaft positioning function. The acetabular bone file comprises an acetabular bone file body, a supporting rack and a rotating shaft, wherein the acetabular bone file body is a semi-spherical cover; a plurality of holes are formed in the acetabular bone file body; a cutting edge is arranged on the side of each hole; the supporting rack is fixed on the bottom of the acetabular bone file body; and the rotating shaft is fixed on the top of the acetabular bone file body. The acetabular bone file is used with a rotating axis positioner; the existing acetabular bone filing mode can be changed; and a curative effect is improved.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of reamer for hip arthroplasty,acetabulum with rotating shaft location.
Background technology
Hip replacement is that acetabular bone is prepared to need with reamer for hip arthroplasty,acetabulum burr cartilago acetabularis, generally by the most small size reamer for hip arthroplasty,acetabulum, start every two millimeters of burrs that go forward one by one, tend to go wrong: after desirable acetabular bone prepares to require each replacing burr, rotating shaft overlapped with last time, generally to realize coaxial as far as possible burr according to patient's experience, so be difficult to accomplish real coaxial burr.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of reamer for hip arthroplasty,acetabulum with rotating shaft location.
The technical solution adopted for the present invention to solve the technical problems is: a kind of reamer for hip arthroplasty,acetabulum with rotating shaft location, comprise reamer for hip arthroplasty,acetabulum, bracing frame and rotating shaft, reamer for hip arthroplasty,acetabulum is hemispherical cover body, which is provided with some holes, hole side is provided with cutting edge, bracing frame is fixed on reamer for hip arthroplasty,acetabulum bottom, and described rotating shaft is fixed on reamer for hip arthroplasty,acetabulum top, and this programme can be realized the coaxial rotating of each burr.
According to another embodiment of the invention, further comprise, described rotating shaft top is hemispherical, and this programme can facilitate the burr rotation of end.
According to another embodiment of the invention, further comprise, described cutting edge is zigzag.This programme can improve the sharpness of cutting edge.
The invention has the beneficial effects as follows, the present invention in conjunction with axis of rotation localizer, can change acetabular bone burr mode in the past by reamer for hip arthroplasty,acetabulum, improves curative effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation one of the present invention;
Fig. 2 is structural representation two of the present invention;
In figure 1, reamer for hip arthroplasty,acetabulum, 11, hole, 12, cutting edge, 2, bracing frame, 3, rotating shaft.
The specific embodiment
As shown in Figure 1, 2, a kind of reamer for hip arthroplasty,acetabulum with rotating shaft location, comprises reamer for hip arthroplasty,acetabulum 1, bracing frame 2 and rotating shaft 3, reamer for hip arthroplasty,acetabulum 1 is hemispherical cover body, which is provided with some holes 11, and hole 11 sides are provided with cutting edge 12, bracing frame 2 is fixed on reamer for hip arthroplasty,acetabulum 1 bottom, and this is common reamer for hip arthroplasty,acetabulum.
Reamer for hip arthroplasty,acetabulum of the present invention is in conjunction with rotating shaft, common reamer for hip arthroplasty,acetabulum 1 top center position add one with rotating shaft guiding under the quarter butt that matches of the hole of boring, i.e. rotating shaft 3, can make all coaxial rotatings of each burr.Rotating shaft 3 tops are preferably hemispherical, can facilitate whole reamer for hip arthroplasty,acetabulum to the heart and rotation.Cutting edge 12 can be the common edge of a knife, also can be preferably zigzag, and zigzag can improve sharpness, strengthens burr power, increases work efficiency.The bracing frame 2 of the present embodiment is cross supporting frame, forms cross hang, and single rod supported also can simultaneously.The present invention can change reamer for hip arthroplasty,acetabulum burr mode in the past, improves significantly curative effect.
