The application range of this robotic system has been specially focused on the orthopaedics field and, more particularly, on the execution of osteotomies. It was therefore necessary to develop a new saw device which would meet medical and--from the robot system point of view--mechanical as well as functional requirements. After describing the device which was developed on the basis of these requirements, a detailed comparative study of off-the-shelf oscillating saws and the new device is given at the end of the paper.

The corrective osteotomy of the thigh bone is used for changing the posture of the hip joint. During surgery, a small cross-sectional slice is cut out of the thigh bone by the use of a sawing device. Our system supports the planning phase of this surgery by allowing interactive visualizations of the cutting planes using a 3D surface-oriented model of the thigh bone derived from computer tomography (CT). It also supports the actual surgery, in which a robot hand is steered towards the predetermined cutting planes, a process that is guided and monitored by a vision system
