Abstract

The invention provides a medical multifunctional operating bit. A bit is arranged at the front end of a rod-shaped body, and the rear end of the rod-shaped body is provided with a connecting handle; a cone frustum is arranged in the front part of the spindle shaped bit, and a first blade area is arranged on the surface of the cone frustum and accounts for one seventh of the spindle shaped bit; a cylinder is arranged on the rear part of the spindle shaped bit, and a second blade area is arranged on the surface of the cylinder and accounts for six sevenths of the spindle shaped bit; and a plurality of triangular cut blades or corundum are arranged on the first blade area, and a plurality of arc cut blades or corundum are arranged on the second blade area. The medical multifunctional operating bit can be used for perforating bone tissues in an operation, or cutting and polishing the bone tissues in the operation, so that the problem of repeatedly changing single-function operating bits in the operation can be solved, massive time for changing bits can be saved, adjacent critical nerves and blood vessels are protected, and clinical risks are effectively reduced.

Description

technical field [0001] The invention relates to a medical surgical drill, in particular to a medical multifunctional surgical drill with a cutting structure and a polishing structure on the drill. Background technique [0002] Bone tissue is the key support and composition structure in the human body. In the process of surgical treatment of bone tissue, the application of surgical drills is becoming more and more extensive. Many types of surgical drills have also been produced for different parts of bone tissue lesions. Most of the currently used surgical drills are spherical drills. During the drilling process, the distance between the working faces is small, which is not suitable for the various needs of clinical operations. Secondly, most of the existing surgical drills are single-function surgical drills, and a kind of drill is only designed for a kind of surgical operation, such as the drill that is responsible for cutting should not undertake the task of polishing. In...
