A Robot eye for surgery

Laparoscopy is a procedure in which a camera is pushed through a small hole in the abdominal wall. It allows a surgeon to operate by television, with instruments inserted through a second hole. The small size of the incisions reduces the trauma for patients and speeds up recovery. Until recently, the procedure has required the presence of a second doctor to guide the camera for the surgeon.

A new development now facilitates this procedure. A robot manoeuvres the camera in response to the surgeon's head. Four tiny transmitters, worn on a headband, send radio signals to a base unit. As the surgeon moves his head left or right, up or down, forwards or backwards, the robot causes the camera to track his movements, enabling him to view the exact area he wishes to see.

B Robot surgery for eye

Techniques derived from virtual reality will soon allow surgeons to feel as well as see the inside of the eye during an operation. During the operation, the surgeon manipulates a set of controls known as the master. These are connected through a high-performance computer to the robot. The robot's limbs move in exactly the same way, except that the movements can be scaled down as much as a thousand times, thus eliminating hand tremor and reducing damage to the eye.

The computer also creates a three-dimensional view of the inside of the eye, which the surgeon can see wearing a virtual reality helmet and 'feel' via a sensory feedback system which emulates the forces generated by cutting with a surgical tool.
