Medical combined operation drill bit

Abstract

The invention relates to a medical combined operation drill bit; the operation drill bit is a rod-shaped body, wherein a spherical drill bit is arranged at one end of the rod-shaped body, and a connection handle is arranged at the other end of the rod-shaped body; two different types of cutting edges are arranged on the spherical drill bit and are positioned in different areas of the spherical drill bit and along the axial direction of the rod-shaped body; a first edge area is arranged at the front part of the spherical drill bit and occupies 1 / 5 to 4 / 5 of the spherical drill bit; a second edge area is arranged at the rear part of the spherical drill bit and occupies 2 / 3 to 4 / 5 of the spherical drill bit; a grinding edge or a cutting edge is arranged on the first edge area; and a cutting edge or a grinding edge is arranged on the second edge area. The medical combined operation drill bit can be used not only for punching osseous tissues in operations but also for cutting and polishing osseous tissues in operations, solves the problem that operation drill bits with simplex functions are replaced repeatedly during operations, saves a great amount of time wasted for replacement of drill bits, protects adjacent important nerves and blood vessels and effectively reduces clinical risks.

Description

technical field [0001] The invention relates to a medical surgical drill, in particular to a medical composite 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. Existing surgical drills are mostly single-function surgical drills, and a drill is only designed for a surgical operation, such as a drill that is responsible for cutting and should not undertake the task of polishing. In the process of bone tissue processing, the drill bit is often broken due to the single function of the drill bit, and the drilling is too deep, which not only damages the surrounding soft tissue, but also entangles the surrounding soft tissue.

Problems solved by technology

[0004] The present invention aims at the deficiencies of the prior art, and provides a medical composite surgical drill, which can be used not only for punching bone tissue during surgery, but also for cutting and polishing bone tissue during surgery, and solves the problem of single-function surgery. The problem of repeated replacement of the drill bit during the operation saves a lot of time wasted in replacing the drill bit, protects the adjacent important nerves and blood vessels, and effectively reduces the clinical risk
