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

Hannes Bleuler, Masayuki Hara, 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, Roger Gassert, Philippe Rétornaz, Laura Santos Carreras, Kaspar Leuenberger

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 ...

Ligament balancing in TKA: Evaluation of a force-sensing device and the influence of patellar eversion and ligament release

Hannes Bleuler, Thomas Maeder, Denis Crottet

Ligament balancing in total knee arthroplasty may have an important influence on joint stability and prosthesis lifetime. In order to provide quantitative information and assistance during ligament balancing, a device that intraoperatively measures knee jo ...

M/ORIS - Medical / Operating Room Interaction System

Sébastien Grange

The routine use of Computer-Assisted Surgery (CAS) in a wide range of surgical procedures and specialties is being hindered by the lack of suitable user interface for surgical environments. While many computer techniques and software exist to assist surgeo ...

Online Classifier Adaptation in Brain-Computer Interfaces

José del Rocio Millán Ruiz, Anna Buttfield

Brain-computer interfaces (BCIs) aim to provide a new channel of communication by enabling the subject to control an external systems by using purely mental commands. One method of doing this without invasive surgical procedures is by measuring the electri ...

A force-sensing device for assistance in soft-tissue balancing during knee arthroplasty

Denis Crottet

Nowadays, the large majority of the instrumentation for orthopaedic surgery consists of mechanical tools with varying degrees of complexity. To increase the accuracy and the safety of orthopaedic interventions, sensors and computers were recently introduce ...

Haptic interface design and control with application to surgery simulation

Ulrich Spälter

This thesis proposes a framework for haptic devices interacting with virtual environments. As application of the theoretical results a haptic device for the surgical training of hysteroscopy, a gynecologic intervention, is presented. Surgery simulators, wh ...

The fetlock tunnel syndrome in horses: literature review and retrospective study

Ursula Röthlisberger

The annular ligament constriction is characterized by a disproportion between the available space and the contents within the fetlock tunnel. The main symptoms are a persisting lameness, distention of the tendon sheath, a typical "notch" when the fetlock i ...

Computational vascular fluid dynamics: problems, models and methods

Alfio Quarteroni

In the cardiovascular system, morphology and functionality are closely related. Altered flow conditions play an important role in the development of arterial disease. In turn, these flow conditions are modified by arterial wall changes. A detailed understa ...

Return of lymphatic function after flap transfer for acute lymphedema

Melody Swartz

OBJECTIVE: The goals of this work were to develop animal models of lymphedema and tissue flap transfer, and to observe physiologic changes in lymphatic function that occur in these models over time, both systemically with lymphoscintigraphy (LS) and locall ...
