Abstract
The utility model relates to a bone cement gun, belonging to the class of medical appliances. A sleeve barrel whose both ends are provided with outer screw is adopted; an upper cover is twisted with the upper end of the sleeve barrel; a screw hole is arranged in the center of the cover; a screw rod is twisted in the screw hole; a piston is coupled with the lower end of the screw rod; a lower cover is twisted with the lower end of the sleeve barrel; a convex hole is arranged in the center o the lower cover. The bone cement gun can push the piston through the screw rod, the bone cement in the sleeve barrel can be quickly and accurately injected in a bone space for plugging, and the marrow spill can be prevented.
Description
This utility model belongs to medical mechanical domain.
The osteoarthrosis necrosis, particularly femur head necrosis of human body generally all need remove to peg graft and change a hip; When the femoral head of excision necrosis, because the pressure bone marrow of bone cavity is often excessive; So when the femoral head of excision necrosis, need in bone cavity, daub into the bone cement shutoff with hands.The problem of this shutoff mode is: shutoff is rapid inadequately, and bone marrow is excessive more.
The purpose of this utility model is: provide a kind of shutoff rapidly reliable Bone cement gun.
Technical measures scheme of the present utility model is: adopt two ends that externally threaded sleeve is arranged, the sleeve upper end has been screwed a loam cake, there is a screw loam cake center, be screwed a screw rod in the screw, the screw rod lower end is connected with a piston, in the sleeve lower end lower cover is housed, there is a convex mouth hole lower cover center.
Bone cement wheel of the present utility model is injected bone cement owing to adopt screw rod to promote piston in bone cavity, the good effect of the rapid bone marrow that accurately and reliably, overflows is arranged.
Accompanying drawing is a structural representation of the present utility model.
5 is that two ends have externally threaded sleeve among the figure, and sleeve 5 upper ends have been screwed a loam cake 3, and there is a screw loam cake 3 centers, have been screwed a screw rod 2 in the screw, and screw rod 2 lower ends are connected with a piston 6; Be screwed a lower cover 7 in the sleeve lower end, there is a convex mouth hole lower cover center, and for laborsaving and crowded os purum cement, lower cover 7 stage casings and piston 6 lower ends can be taper.Convenient in order to load bone cement, on sleeve 5 hypomere walls, a square hole is arranged, at this moment need to be with a big envelope 4 in the sleeve outside; During use, rotary screw 2 carries piston 6 to the upper end, and bone cement is installed to the sleeve 5 from square hole, pushes away big envelope with square hole envelope shelves with subordinate, rotation moving rod 1 and screw rod, and piston 6 moves down, and bone cement is discharged from the convex mouth hole of lower cover 7 inject bone cavity.
