robotic surgery: change in new surgery techniques

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. ‎
