Abstract

The invention discloses a novel medical abrasive drill. The novel medical abrasive drill consists of a drill bit, a drill body and a drill shank, wherein the drill body is of a cone structure; the large-diameter end of the drill body is connected with the drill shank; the drill body is in welded connection with the drill shank; the small-diameter end of the drill body is connected with the drill bit; the drill bit is in welded connection with the drill body; the drill bit is of a solid sphere structure. The novel medical abrasive drill has the advantages that the hexagonal drill shank is adopted; by the combined structure of the cone drill body and the solid sphere drill bit covered by solid dots, the effects of high bone-shaving action, no damage to other parts of a human body and convenient mounting are achieved.

Description

technical field [0001] The invention belongs to the field of medical drills, in particular to a novel medical drill. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, center drills, flat drills, deep hole drills and casing drills. Although countersinking drills and countersinks cannot drill holes in solid materials, they are also customarily classified as drill bits. During the working process of digging, the drill bit rotates with the vertical shaft and moves axially at the same time. The soil is cut under the torque and axial force of the drill bit, and loosened under the extrusion and centrifugal force of the working blades, forming a soil flow that is pressed to the pit wall and lifted to the surface along the page. When the soil flow moves to the place where there is no pit wall, the broken soil is thrown around the pit due to the ...
