Patent attributes
Disclosed is a mechanical teleoperated device comprising i) a handle (30) placed in a proximal part of the device, having a plurality of handle links interconnected by respective handle joints, ii) an end effector (31) placed in a distal part of the device, having a plurality of end-effector links interconnected by respective end-effector joints, iii) a transmission system arranged to kinematically connect the end effector to the handle such that movements of the end effector correspond to movements of the handle, comprising at least one arrangement of a plurality of rotatable elements (41a-d) coaxially mounted together about an axis and arranged to rotate independently from each other, b) first transmission means comprising driving elements (62a-c) which are arranged to actuate in rotation of the plurality of rotatable elements (41a-d) based upon movements of the handle, c) second transmission means comprising driven elements (63a-c) which are arranged to be driven by rotation of the plurality of rotatable elements resulting in movement of the end effector links, wherein the transmission system is configured for removably coupling together the first and second transmission means wherein each driven element is removably coupled to one corresponding rotatable element.
