In keyhole surgery the operation is carried out by inserting miniature instruments through tiny puncture holes. The surgeon sees what he is doing by referring to images from a tiny camera called a laparoscope.
At present a human assistant operates the laparoscope, to free both the surgeon's hands for the operation itself. Now a British company, Armstrong Products, has linked a laparoscope to a headband with a sensor which detects movements of the surgeon's head, and moves the camera accordingly, thereby eliminating camera shake.
The first full operation using the new laparoscope was carried out by a consultant, David Dunn, at the Evelyn Hospital in Cambridge earlier this month, to repair a hernia.Reuse content
