Abstract:
1. A manipulator for an instrument for minimally invasive surgery, having at a proximal end a handle for operating the instrument, and wherein the instrument is removably placed at a distal end, and wherein a parallelogram construction is provided between the proximal end and the distal end for guaranteeing an unambiguous positional relationship between the handle and the instrument, and wherein the parallelogram construction is coupled with a system of bars for controlling the position of the parallelogram construction, the bars of the system of bars being connected to the parallelogram construction as well as to each other by means of cardan joints, said system of bars being mounted on a horizontally extending main arm, and wherein on this main arm two next to each other upwardly extending arm sections are provided that are interconnected via a first coupling arm, which arm sections carry operating arms that are coupled with a horizontal arm of the parallelogram constructions as well as being mutually interconnected via a second, horizontally extending, coupling arm.
