The invention discloses a bone drill with a function of adjusting hole drilling directions. The bone drill comprises a fixture head and a drill rod. The drill rod is fixedly mounted on the fixture head, a through hole is formed in the fixture head, a hollow flexible shaft lever is mounted in the through hole, transmission mechanisms of the drill rod and the bone drill are respectively connected with two ends of the flexible shaft lever, the flexible shaft lever can be driven by the transmission mechanisms to rotate, and accordingly the drill rod can be driven to rotate; lifting seats are arranged at the inner front end and the inner rear end of the drill rod, telescopic rods are arranged on the lifting seats, and the ends of the telescopic rods of the two lifting seats are connected with one another. The bone drill has the advantages that the drill rod can be driven by the flexible shaft lever and the telescopic rods inside the drill rod to rotate, accordingly, hole drilling angles can be adjusted, and the rigidity of drilled holes can be guaranteed; the bone drill is simple in structure, convenient to operate and applicable to all types of hole drilling surgery.
Description
technical field [0001] The invention relates to the technical field of medical bone drills, in particular to a bone drill capable of adjusting the angle and direction of drilling. Background technique [0002] Medical bone drill is a tool commonly used in shell surgery. It is mainly used to drill holes in bones to bury the caps of screws, which can play the role of tension nails. The operating environment during surgery is often very narrow. Due to Most of the bone drills are vertical drilling, which causes the operation to remain unchanged, and some medical bone drills that use flexible shafts to achieve adjustment are not rigid enough, which is prone to problems, and the angle adjustment when drilling The accuracy is not high, so it is particularly important to solve this type of problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a bone drill capable of adjusting the drilling direction, which drives th...
