Abstract:

Medical science experts have reached scientific and technological improvements in recent decades and have turned surgery into a routine treatment by controlling its complications. Cumulative changes in surgery resulted in decreased pain and discomfort and controlled complications. The developmental path and changes have resulted in endoscopic with minimal invasive surgery (MIS) in which only few small incisions are made on the body and surgery is done through video control which otherwise required more and larger incision with more complication. But this method with all the usefulness has some problems such as discrepancy between surgeon's eye and hand, indirect and two dimensional vision, limited degree of freedom of instruments and surgeon's fatigue. In addition this type of surgery needs complete education and skill. The sum of these factors limits the use of MIS. In order to overcome these problems, robotic surgery method is invented. In this method like MIS, a few small incisions are made and surgeon is able to perform the surgery from a distance by a three dimension vision by controlling the arms of robots which are similar to the movements of human and are placed around the table of surgery. Despite all the benefits of this method, its high cost limits its use. Although it's hopeful that with the improvements of this method and its usefulness, the costs will decrease.
