Patent ID: 8821512

Claim:
Manipulator comprising: a control unit ( 1 ), having a handle ( 4 ) adapted to be held in one hand, at least one control member ( 4 a - 4 d ), mounted on the handle ( 4 ), and adapted to be loaded by at least one finger of the hand holding the handle ( 4 ), a connecting arm ( 2 ), extending along an arm longitudinal axis (I-I), having a proximal end ( 2 a ) in which the control unit ( 1 ) is mounted, and having a distal end ( 2 b ), a working unit ( 3 ), mounted on the distal end ( 2 b ) of the connecting arm ( 2 ), including a tool support ( 5 ) adapted to support a tool ( 6 ), and actuated by said at least one control member ( 4 a - 4 d ), the handle ( 4 ) being elongate along a handle longitudinal axis (IV-IV) and being conformed to be held in the palm of the hand ( 200 ) with the thumb ( 201 ) opposite the other fingers ( 202 ) to surround its lateral surface in a holding section ( 40 ), the handle ( 4 ) being articulated, in the control unit ( 1 ), with at least one degree of freedom in rotation about a first articulation axis ( 4 e ) transverse to its handle longitudinal axis (IV-IV), the first articulation axis ( 4 e ) of the handle ( 4 ) being in an intermediate position along the handle longitudinal axis (IV-IV), with the result that the holding section ( 40 ) extends either side of the first articulation axis ( 4 e ) of the handle ( 4 ), the first articulation axis ( 4 e ) intersecting the longitudinal axis (I-I) of the connecting arm ( 2 ), wherein: the handle longitudinal axis (IV-IV) intersects the longitudinal axis (I-I) of the connecting arm ( 2 ), the handle ( 4 ) is fixed against axial rotation about its longitudinal axis (IV-IV) relative to the control unit ( 1 ), the manipulator has no direct or indirect coupling means between the movements of the handle ( 4 ) relative to the control unit ( 1 ) and the movements of the tool support ( 5 ) and the tool ( 6 ) relative to the connecting arm ( 2 ).
