Tactile Feedback Improves Performance in a Palpation Task: Results in a VR-Based Testbed

Hannes Bleuler, Roger Gassert, Evren Samur, Laura Santos Carreras

Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient This physical separation prevents surgeons from performing direct haptic exploration of tis ...

Robotic system for spinal and other surgeries

Charles Baur, Szymon Kostrzewski

The present invention relates to a method, such as a surgical method for assisting a surgeon for placing screws in the spine using a robot attached to a passive structure. The present invention also related to a method, such as a surgical method for assist ...

Extending the body to virtual tools using a robotic surgical interface: evidence from the crossmodal congruency task

Olaf Blanke, Hannes Bleuler, Giulio Rognini, Jane Aspell, Michiel van Elk, Ali Sengül

The effects of real-world tool use on body or space representations are relatively well established in cognitive neuroscience. Several studies have shown, for example, that active tool use results in a facilitated integration of multisensory information in ...

Dionis: A novel remote-center-of-motion parallel manipulator for Minimally Invasive Surgery

Hannes Bleuler, Reymond Clavel, Giulio Rognini, Laura Santos Carreras

The large volume and reduced dexterity of current surgical robotic systems are factors that restrict their effective performance. To improve the usefulness of surgical robots in minimally invasive surgery (MIS), a compact and accurate positioning mechanism ...

Tendon-Based Transmission for Surgical Robotics: Systematic Experimental Friction Modeling

Hannes Bleuler, Patrick Schoeneich, Ricardo Daniel Rita Beira, Ali Sengül

Increased miniaturization of surgical instruments is essential to successfully perform surgical procedures in restricted areas as in many applications of minimally-invasive surgery. Miniaturization permits increase in dexterity and decrease in access incis ...

Design and Psychophysical Evaluation of a Tactile Pulse Display for Teleoperated Artery Palpation

Hannes Bleuler, Philippe Rétornaz, Roger Gassert, Laura Santos Carreras

During traditional open procedures, surgeons directly palpate tissues before dissecting them. In this way, they can avoid the accidental damage of hidden arteries that can lead to fatal hemorrhage. New Minimally Invasive Surgical (MIS) techniques progressi ...
