Our system combines a virtual reality display with high-fidelity haptic rendering to provide assistance and guidance of the medical gesture. Specifically, the system is designed to improve the accuracy of blind needle placement within tissues. The proposed technique actively helps the surgeon while keeping him in control of the procedure. We have recently developed an experimental setup for CT-guided biopsy. The setup features a high-precision haptic device connected to the biopsy needle, combined with a graphical interface. The haptic system guides the surgeon's hand to the target tissue based on CT data, whereas a real-time, graphical visualization of the tool trajectory provides navigation information. The setup requires rigid registration of the patient with respect to the haptic interface. Tests have been performed in the presence of radiologists to validate the proposed concept, and...

The novelty of this device is that it is a 3 degrees of freedom desktop system, supporting pronation/supination, flexion/extension and grasping hand movements and it is totally dedicated, in its current state, to children. The kinematics and the construction aspects of this desktop device are presented. Its different advantages are discussed to point out the benefits of this structure. Control and force feedback aspects combined with virtual reality are also presented. A prototype of the “Handreha” is realized and presented and the performances discussed. The first evaluations with hemiplegic children really show that the mechanical design of the device fits the targeted specifications

The force-feedback interaction provides a very intuitive, efficient and reliable way for quick manipulation of nanoscale objects. Unlike other nanomanipulators, ours allows the user to feel the actual tip-sample interaction during the manipulation process. Various modes of manipulation have been implemented and evaluated. As a proof of concept, we show a contact-mode nanomanipulation of a carbon nanotube and a noncontact manipulation of silicon beads. In addition to nanomanipulation itself, all relevant signals can be recorded during the manipulation process which allows quantitative interpretation of nanomechanics experiments.
