We are developing a laser-based, non-contact cutting tool to perform osteotomy without mechanical stress and vibrations. With respect to conventional mechanical approaches, the laser method reduces procedure invasiveness while significantly increasing cut accuracy and precision. Furthermore, the development of a positioning system will allow 3D cuts that are currently impossible with a saw.
Our primary objective is to provide a surgeon with an instrument that enables him to apply a computer-assisted pre-operative plan to an intraoperative situation.
Our research focuses on two areas: (1) navigation and (2) mechanical positioning.
We are currently evaluating several semi-active and haptic systems that will help the surgeon to position the laser beam over the patient in an easy and accurate manner.
Laser-based cutting will enable the use of bone fixation implants to be avoided. In addition, structural joints (dovetail, mitre, etc.) can be produced and assembled. Thus, this technology offers substantial potential for improving maxillofacial and ENT surgery.
