The utility model provides an annular bone drill of getting, including being hollow ring bit, ring bit's tip is equipped with the cockscomb structure cutting part, ring bit's top is equipped with the sleeve of dismantling the connection with it, telescopic top is equipped with fixed connection's connecting plate with it, be equipped with the through-hole on the connecting plate, be equipped with the locating lever of dismantling the connection with it in the through-hole, be equipped with solid fixed ring on the locating lever, gu fixed ring is located in the sleeve, the cover has the spring on the locating lever, the one end of spring with gu fixed ring fixed connection, the other end of spring with connecting plate looks butt, locating lever, ring bit with the axle center of through-hole, be equipped with the relative hole groove that sets up on the ring bit, still be equipped with a plurality of louvres on the ring bit.
Preferably, the length of the positioning rod is longer than that of the ring bit.
Preferably, the top of the positioning rod is provided with a clamping block.
Preferably, the through hole is a screw hole, a first external thread is arranged on the periphery of the positioning rod, a second external thread is arranged on the outer wall of the annular drill bit, an internal thread is arranged on the inner wall of the sleeve, the first external thread is in threaded connection with the screw hole, and the second external thread is in threaded connection with the internal thread.
The beneficial effects of the utility model reside in that:
the annular bone drill of the utility model, when the bone drill is used for taking bones, the positioning rod is pressed against the bones, and the spring is in a compression state, the positioning rod is drilled to a required depth by rotating the device, then the positioning rod is reversely driven to rotate, so that the positioning rod is separated from the bones, then the device can be continuously rotated, thereby the bone with even bone wall thickness can be conveniently collected by drilling the required depth in the bones through the saw-toothed cutting part at the end part of the annular drill bit, after the bone drill is finished, the positioning rod is further reversely driven to rotate, so that the through hole is separated from the positioning rod, thereby the through hole loses the limit on the positioning rod, therefore, the spring can reset, thereby the fixing ring on the positioning rod can jack the bones drilled by the annular drill bit, until the bone that drills in the ring bit by on the locating lever with solid fixed ring is ejecting completely, and then can make things convenient for quick take out the bone, the follow-up bone grafting work of being convenient for goes on, in addition, through the effect of louvre, can improve radiating efficiency at the drill bone in-process, avoid the serious condition of generating heat to take place.
