Latest Robotocs Surgery techniques

Robot-assisted surgery is the latest development in the larger movement of endoscopy, a type of minimally invasive surgery--the idea being that less invasive procedures translate into less trauma and pain for patients. Surgery through smaller incisions typically results in less scarring and faster recovery. It's not that robots are changing the basics of surgery. Surgeons are still cutting and sewing like they have been for decades. Robots represent a new computer-assisted tool that provides another way for surgeons to work.

Rather than cutting patients open, endoscopy allows surgeons to operate through small incisions by using an endoscope. This fiber optic instrument has a small video camera that gives doctors a magnified internal view of a surgical site on a television screen.

In abdominal endoscopy, known as laparoscopy, surgeons thread the fiber optic instrument into the abdomen. First performed in the late 1980s, laparoscopy is now routine for many procedures, such as surgery on the gallbladder and on female organs.
