Intelligent Drill

(with emergency braking system)


Intelligent 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.

  • Drilling speed in a layer of cortical/compact bone and cancellous/spongy bone is different due to the difference in their densities.
  • Intelligent Drill is equipped with a sensor that detects the change in rotational speed as it penetrates the bones.
  • Drilling automatically stops after penetrating the second layer of cortical bone by sensing the sudden change of drill speed.
  • The auto-stoppable by sensing the change in drilling speed can be set at any point of drilling. This technology is applicable to almost all drilling parts and is useful in various settings of surgery.
  • Intelligent Drill provides a fine control of drill speed and ensures better performance during a surgical procedure.
  • Sensitivity of drilling sensor can be modified to suit different types of orthopedic surgeries. Thereby, Intelligent Drill reduces the possibility of risk, negligence, or unfavorable accident during operation.

The estimate of global surgical drill market is USD 410 million in 2017 and is expected to grow at a CAGR of around 4.5% from 2018 to 2026.


    The patent is registered in South Korea, Europe, China, Indonesia while it is pending in the USA, Japan, India, and Vietnam.

R&D status

  • A simulation experiment for testing an auto-stop function of Intelligent Drill was conducted successfully in April 2020.
  • The first prototype of Intelligent Drill was produced in 2017.
  • A sensor software for Intelligent Drill is currently completed.
  • The prototype production of intelligent disposable drills will be proceeded with Daegu-Gyeongbuk Medical Innovation Foundation (DGMIF).
