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

The present invention is a surgical drill with an automatic stop function that can stop its operation while drilling bone tissues. This prevents damage to the surrounding tissues and helps the surgeon to safely drill through cortical layer. The drill has a smart module that uses a non-contact distance measuring device to automatically calculate the depth of bone drilling without adding any extra components. The drill can be easily disinfected for aseptic packaging.

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 bit, so that the electrical bone drill has the advantages of reducing the force or load required for the surgeon's drilling operation and shortening the bone drilling time, but it still has the disadvantage that the surgeon is unable to feel the drop of bone drilling resistance through both hands and stop the bone drilling operation timely.

If the surgeon cannot stop drilling bone tissues timely, the high-speed drill bit may damage blood vessels, nerves, muscles or fascia more seriously than the manual bone drill.
