touch-sensitive-virtual-reality-tools-for-surgeonsSince most of the procedures in modern surgery are performed with remote controlled tools that can be inserted into the body using only small incisions, laparoscopic surgery skips the need for large incisions and, in turn, usually results in shorter recovery times for patients. An interdisciplinary team of researchers, led by Rensselaer Polytechnic Institute, is… »

New steps in surgery – Minimally Invasive Robotic Surgery

By Damir Beciri
10 September 2009

dlr-mirosurgeConventional minimally invasive surgery (MIS) is per­formed through small incisions in the patient’s skin, pre­serving healthy tissue. The surgeon works with long slender instruments, and is separated from the operation area. This arrangement challenges the surgeon’s skills due to lost hand-eye-coordination and missing direct manual con­tact to the operation area. Therefore, many sophisticated procedures cannot… »
