RIM-Drill is an Orthopedic power tool device that automatically stops at the distal bone based on the results of an analysis of the difference in the rotational speed of the drill bit according to the difference in strength and the density of the bone tissue.
Bone drilling for perforation is a common procedure in various fields of surgery including orthopedics, neurosurgery, plastics and reconstructive, craniomaxillofacial and ear nose and throat (ENT). For example, in order to fix a ruptured bone in orthopedic surgery, drilling is required to make a hole for screw insertion. According to stop the drill, it only relying on the doctor’s sensation. The drill bit rotates at an average speed of 1,000 RPM, and if the drill advances a bit more after the penetration, the soft tissues surrounding the bones (blood vessels and nerves) may cause serious damage or even fatal medical malpractice.
