Technology Description


The system we developed accurately identifies the moment of the drill from the bone because this parameter is a basic basis for the entire operation of the system.

The system analyzes information coming from sensors based on various technologies. The system consists of a adapter that will be attached to the drill itself and an additional monitoring period attached to the human body independently. The information is processed in real time and enables the detection of the moment of the drill from the bone.

After identifying the moment of the drilling of the drill from the bone, the system will perform a series of active actions that will stop the drilling and penetration of the drill beyond the required. At the same time, the system will provide an accurate indication of the depth of the hole.

The following are the technologies underlying the system and their programming:


  1. Acoustic monitoring to detect the breakthrough moment: There is a great deal of difference in sound frequencies when moving through the bone walls. We have developed a suitable algorithm to contract the completion of drilling when using sound waves

  1. Ultrasound technology allows the identification of small cracks within the bone and, in addition, identifying the return of the rays as a direct result of the emergence of the drill as soon as it penetrates the bone. 

  2. Mechanical stress monitoring: use of the mechanical work on the drill while drilling bones, and analysis of the pattern for the moment of breakout


System Components:

  1. General adapter for medical drillings - The adapter tracks many mechanical parameters that can be used to effectively monitor the drilling (eg torque, rotational speed, vibration of the forces of pressing and pulling). In addition, the drill adapter allows the drilling to be stopped immediately by stopping the drill rotation and preventing its movement towards the object (continued penetration).

  2. Acoustic ultrasonic sensor unit (AUS) A biological sensor unit (based on acoustics and ultrasound) attached to the patient near the surgical area, which collects data and performs its initial minimal analysis and processing in real time This information is transmitted in real time to a main processing and control unit (server) Located in the operating room.

  3. Control Unit (CU) - Installed in a portable manner, in a manner that does not transmit waves or noise that may interfere with the additional equipment found during the operation. The CU will include a touch screen and a dedicated GUI that will enable the surgeon to interact with the system (receiving information and control).

  4. Control system - the control system is running the central algorithm of the system that processes the information collected and according to which is given an indication of the moment of breakout. The control software monitors the data flowing from the sensory sensors on a continuous basis, while performing the information and cleaning the noise in the system. Continuous pattern matching is made between pre-saved patterns of bone transitions and the collected data. The system also contains a database that allows the system to intelligently handle the fundamental difference between the different bones and similar bones in different people.
