Surgical drill and method of controlling the automatic stop thereof

Abstract

A surgical drill includes a drill bit, a driving device connected and electrically coupled to the drill bit, and a smart module electrically coupled to the driving device. In a bone drilling work, the smart module monitors an electrical signal of the driving device, and if the electrical signal shows a step drop, the smart module will send a stop command to the driving device to stop the operation of the driving device.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of medical instruments, and more particularly to a surgical drill and a method of controlling the automatic stop of the surgical drill solar panel module.BACKGROUND OF THE INVENTION[0002]Surgical bone drills are mainly divided into manual drills and electrical drills. In the manual bone drill, the rotating speed, the drilling depth, and the start and end of the drill are controlled manually by a surgeon. The surgeon operates the bone drill based on experience and hand feel. At the moment of drilling through bone tissues, the bone drilling resistance drops significantly and the surgeon's hand may sense such drop significantly, but the surgeon is unable to stop the drilling operation instantaneously. Therefore, blood vessels, nerves, or fascia may be drilled and damaged easily, and the patient safety may be jeopardized.[0003]On the other hand, the electrical bone drill steadily receives electromechanical torque fro...

AI Technical Summary

Benefits of technology

[0018]The surgical drill may be stopped immediately and automatically at the moment of drilling bone tissues by a drill bit. The automatic stop of the operation of the surgical drill alerts the surgeon that he has already drilled through the cortical layer already. The automatic stop also provides the safety effect of protecting the tissues, blood vessels, muscles, nerves and fascia behind the cortical layer and prevents them from being damaged by the surgical bone drill that drills through the cortical layer.

[0019]The smart module of the present invention is compatible with surgical drill of any model and specification without the need of changing the structure of the surgical drill or adding additional components or modules. The smart module of the present invention has the

Problems solved by technology

At the moment of drilling through bone tissues, the bone drilling resistance drops significantly and the surgeon's hand may sense such drop significantly, but the surgeon is unable to stop the drilling operation instantaneously.

Therefore, blood vessels, nerves, or fascia may be drilled and damaged easily, and the patient safety may be jeopardized.

On the other hand, the electrical bone drill steadily receives electromechanical torque from a mechanical structure to achieve an automatic rotating effect of a drill b
