Manipulator for gripping parts in difficult to access places in minimal invasion surgery

摘要

The distal fingers (8) of the manipulator can be operated from the proximal end (1) by levers which move the wires. The wires run in a sleeve (2). The end of sleeve section (6) which acts as hand can be deflected by one of three wires which run in the sleeve near its circumference. The operating wires for the hand are moved by deflecting a spiral spring (5). The gripping fingers are formed by hooks at the ends of at least two wires which run along the centre of the sleeve.
