Abstract

The invention discloses a crushed bone collection drill, and belongs to the technical field of tooth implantation. The crushed bone collection drill comprises a cylindrical hollow barrel, an external hexagonal connector, a handle and a crushed bone drill bit, annular saw teeth are arranged at the upper end of the hollow barrel, the lower end of the hollow barrel is fixedly connected with the external hexagonal connector, the lower end of the external hexagonal connector is fixedly connected with the handle, the hollow barrel, the external hexagonal connector and the handle are coaxial, the crushed bone drill bit is detachably embedded into the hollow barrel, and a spiral crumb guide channel is formed in the side wall of the crushed bone drill bit. The crushed bone collection drill can be connected with a manual drill, can be also connected with an electric drill, radial stress cannot be applied to bones with drilling holes, bones cannot be fractured when holes are drilled, drilled bone crumbs are conveniently collected in the collection drill, and healing of soft tissues cannot be affected.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a bone crushing drill. Background technique [0002] When implanting artificial prostheses or taking bone yourself, it is often necessary to fill in some broken bone to increase the speed of healing. Collect broken bone now and mainly be to drill with drill bit, yet existing drill bit has the following defects in bone extraction: [0003] 1. The drilled bone debris is scattered everywhere and is not easy to collect; [0004] 2. Bone chips are scattered in the wounds of soft tissues such as muscles and mucous membranes, affecting the healing of soft tissues; [0005] 3. When the existing drill bit drills holes, radial stress will be generated on the bone, which will easily cause cracks or even fractures in the bone, causing serious trauma to the patient. Contents of the invention [0006] The present invention aims to provide a bone fragment collection drill, which ca...
