Robotic surgery is dramatically different from traditional surgery. Two of the most significant differences are that the surgeon performs the robotic-assisted procedure while looking into a special computer screen instead of looking at the patient and the instruments are controlled using a telemanipulator or remote manipulator instead of being directly controlled by the surgeon.
There are several tiny, highly specialized surgical tools attached to the robot’s arms. During a robotic surgery procedure, the surgeon directs the movements of the robot and the attached tools while sitting at a computer station. The small cut is first made at the site of the surgery through which an endoscope is inserted into the body. The endoscope is a thin tube with a camera attached at the end that is inserted into the body. The camera acts as the surgeon’s eyes inside the body and sends out magnified 3-dimensional images of organ to be operated on. The magnified views allow the surgeon to get a better look at the site to be operated upon. To perform the procedure, the robot matches the surgeon’s hand movements, using its smaller precision devices.
Robotic surgery can be performed through smaller cuts as compared to open surgery. That along with the smaller, more precise movements that are possible with this technique give it several advantages over more conventional endoscopic techniques.
Robotic surgery is being used for several different minimal invasive surgical procedures, including:
Robotic-assisted surgery cannot be used for some highly complex procedures. Also, it can take longer to perform mainly because of the amount of time needed to set up the robot for that particular procedure.
