Robotic prostate cancer surgery. Surgeon at the console of a Da Vinci robot surgeon, controlling laparoscopic arms (right) to remove a carcinoma (cancer) from the prostate gland of a 70-year-old man. The surgery itself is shown on the screen at left, with a surgical monitoring device at lower left. The patient (not seen) is off screen at lower right. The removal of all or part of the prostate gland is called a prostatectomy. Da Vinci is a remote-controlled surgical system, developed and produced by the US company Intuitive Surgical. It has four robotic arms that carry tools specific to the operation and other more general surgical implements for procedures such as suturing (stitching) and clamping. A specially trained surgeon operates the system from an ergonomically designed console using remote joysticks with force-feedback.
