The collaborative effort between fundamental science, engineering and medicine provides physicians with improved tools and techniques for delivering effective health care. Minimally invasive surgery (MIS) techniques have revolutionized the way a number of surgical procedures are performed. Recent advances in surgical robotics are once again revolutionizing MIS interventions and open surgery. In...

Conventional microsurgery requires large incisions and extensive dissection while it is performed in a small operating field. In this context, the concept of endoscopic microsurgery appears to be a logical evolution. We rely on four years of practical experience using the Da Vinci robot at the European Institute of telesurgery in Strasbourg, France. To date, 50 patients have been operated on by...

In this paper, telesurgery and surgical simulation are introduced as parallel research problems of haptic interfacing to real and virtual surgical environments. The analytical tools of systems and control theory and robotics are used to address several research problems in these areas. The discussion on telesurgery is centered around the UC Berkeley/UC San Francisco Laparoscopic Telesurgical Wo...

The craft of surgery has always relied on the use of instruments. Innovations in surgery have paralleled innovations in instrumentation. Advances in surgical instrumentation continue today and have enabled huge strides in surgical procedures and outcomes during this generation. Computers and related technology are now changing the interface between the surgeon and the patient, and are poised to...

Minimally Invasive Surgery is the most important revolution in surgical technique since the early 1900s. Its development was facilitated by the introduction of miniaturized video cameras with good image reproduction. The marvels of electronic and information technology have strengthened the biochemical and molecular power of diagnosis and the surgical and medical management of gynecology, trans...

Securing telemedicine services is essentially a critical and urgent topic. However, in many existing telemedicine systems security related issues are seldom seriously considered. In this paper, we introduce an image-based simulated system for kyphoplasty telesurgery, wherein special attentions are drawn to address the security problems. Among others, various security requirements of the system ...

Previous research on teleoperation has focused on manipulation of hard objects. However, the design constraints are different in applications that involve manipulation of deformable objects, such as robotic telesurgery. In this paper a new measure for fidelity in teleoperation is introduced which quantifies the teleoperation system’s ability to transmit changes in the compliance of the environm...
