Minimally Invasive Photopolymerization In Intervertebral Disc Tissue Cavities

Dominique Pioletti, Christophe Moser, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

Photopolymerized hydrogels are commonly used for a broad range of biomedical applications. As long as the polymer volume is accessible, gels can easily be hardened using light illumination. However, in clinics, especially for minimally invasive surgery, it ...

A New Noninvasively Adjustable Glaucoma Drainage Device

Adan Villamarin

Glaucoma is an irreversible disease affecting the eye, leading to progressive loss of vision and eventually to total blindness. It is often related to high intraocular pressure (IOP), which results from increased outflow resistance to aqueous humor. The fi ...

Design of Dexterous Mechanical Systems for Intuitive Telemanipulation in Minimally Invasive Surgery

Ricardo Daniel Rita Beira

Major progress in abdominal surgery has occurred over the last decades with the introduction of laparoscopic and minimally invasive techniques in the operating room. These innovative procedures attracted much attention due to several advantages: the need f ...

Increasing Haptic Fidelity and Ergonomics in Teleoperated Surgery

Laura Santos Carreras

Over the past few decades, surgical procedures have made enormous progress, shifting from traditional open procedures to less and less invasive approaches, with the promise of smaller incisions, less complications, better cosmetic results and shorter recov ...

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 ...

Influence of force and torque feedback on operator performance in a VR-based suturing task

Hannes Bleuler, Roger Gassert, Laura Santos Carreras, Ricardo Daniel Rita Beira, Ali Sengül

The introduction of Minimally Invasive Surgery (MIS) has revolutionised surgical care, considerably improving the quality of many surgical procedures. Technological advances, particularly in robotic surgery systems, have reduced the complexity of such an a ...

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

Hannes Bleuler, Patrick Schoeneich, Masayuki Hara, 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 ...

Modeling and Design of a Gripper for a Robotic Surgical System Integrating Force Sensing Capabilities in 4 DOF

Hannes Bleuler, Giulio Rognini, Laura Santos Carreras, Ricardo Daniel Rita Beira, Ali Sengül, Mathieu Joseph Charles Stephan

This paper reports the design of a Minimally Invasive Surgery (MIS) gripper with four degrees of freedom force sensing capabilities. It will be used to provide force feedback during surgical interventions in which the surgeon will remotely manipulate surgi ...

VR simulation of interventional radiology and microsurgery

Fei Wang

Currently trainees typically learn surgery techniques directly on mocks, animals or cadavers. For safety, cost and ethics reasons, one cannot try all possible strategies to achieve efficient learning. Virtual Reality (VR) based surgery training systems int ...

Modélisation mécanique de fils pour la simulation chirurgicale

Lindo Robert Duratti

Minimally Invasive Surgery (MIS) represents one of the major progresses in surgery in the last decade. In general, it is based on the application of small body-cuts through which instruments are inserted into the patient's body allowing the surgeon to carr ...
