Body bone impaction bone grafting art；The bone source of domestic impaction bone grafting is sheet femoral head mostly, and sheet femoral head is by entire allogeneic stock
Bone is longitudinally cutting to be formed.After removing sheet femoral head cortical bone, the production of skeletal grain, which needs manually to be stung with rongeur, to be removed, skeletal grain
Shapes and sizes it is uneven and not easy to control.Especially when bone source is from person between twenty and fifty, since between twenty and fifty people's bone matter is hard, place
It manages skeletal grain size that is time-consuming and laborious, and being not easy to grasp temporarily required in art, to increase operating time, increases intraoperative hemorrhage
Amount and increase postoperative infection risk, and the waste in bone source is inevitably resulted in, increase patient economy burden.
Summary of the invention
The object of the present invention is to provide a kind of structure is simple, sheet femoral head skeletal grain producing device easy to use.
The object of the present invention is achieved like this:
A kind of sheet femoral head skeletal grain producing device, what is matched including osteotomy device and with the osteotomy device hits bone object, and described section
Bone object include chassis and be arranged on the chassis for by the sheet femoral head for removing cortical bone be fabricated to the several of skeletal grain and
The aperture of equidistantly distributed, the chassis periphery are equipped with the baffle for fixing sheet femoral head.
The bone object that hits includes handle and is fixedly connected with the handle and bottom plate identical with the chassis phase shape.
The chassis with a thickness of 3 ~ 10mm, the chassis is circle, and the diameter on the chassis is 20 ~ 90mm, the bottom
The diameter of disk is greater than the diameter of the bottom plate.
The aperture is square, and the side length of the aperture is 4 ~ 10mm.
The distance between at the top of the baffle and chassis upper surface is 1 ~ 8mm.
The material of the osteotomy device is medical steel.
The material for hitting bone object is medical steel.
The beneficial effects of the present invention are: the configuration of the present invention is simple, the setting of aperture, can will remove the piece of cortical bone on chassis
Shape femoral head is fabricated to the identical skeletal grain of shape and size, reduces or remits the cumbersome of skeletal grain manufacturing process in art, have save trouble, be laborsaving,
Bone source is saved, operating time is reduced, reduces intraoperative blood loss amount, reduces the advantages of postoperative infection risk, simultaneously because bone source is saved,
Mitigate patient economy burden, the setting of the different sizes and shapes of aperture can make the bone of different sizes and shapes as needed
Grain, has a wide range of application.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of osteotomy device of the present invention；
Fig. 2 is the sectional view in the direction A-A of Fig. 1；
Fig. 3 is the structural schematic diagram that the present invention hits bone object；
In figure: chassis 1, aperture 2, baffle 3, handle 4, bottom plate 5.
