Patent ID: 8613740

Claim:
A manipulator comprising: a control unit ( 1 ) having a handle ( 4 ) capable of being held by one hand, at least one control member ( 4 a - 4 c ) mounted on the handle ( 4 ) and capable of being activated by at least one finger of the hand holding the handle ( 4 ), a connecting arm ( 2 ) extending along a longitudinal axis of the arm (I), having a proximal end ( 2 a ) in which the control unit ( 1 ) with the handle ( 4 ) 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 ), comprising a tool support ( 5 ) carrying, or capable of receiving, a surgical tool ( 6 ) and able to be actuated by control members ( 4 a - 4 c ) according to at least one degree of freedom of movement, in which: the handle ( 4 ) comprises a gripping portion ( 4 e ) having a gripping surface about a longitudinal axis of the handle (III) which is shaped so as to allow a same manual gripping in any angular orientation about the longitudinal axis of the handle (III) and to permit a uniform rotation of the handle ( 4 ) in the hand or between the fingers, the handle ( 4 ) is fixed to the proximal end ( 2 b ) of the connecting arm ( 2 ), the longitudinal axis of the handle (III) is colinear with the longitudinal axis of the arm (I), said control members ( 4 a - 4 c ) are shaped so as to be accessible about the handle ( 4 ) in an annular control area in the vicinity of one end ( 4 f ) of the gripping portion ( 4 e ), whatever the orientation of the hand about the longitudinal axis (III) of the handle ( 4 ), wherein the working unit ( 3 ) is able to be actuated by a first control member ( 4 a ) of said control members ( 4 a - 4 c ) in at least one lateral inclination movement ( 12 ) of adjustable amplitude, so that the working unit ( 3 ) adopts an inclination in which it is oriented in a direction of inclination (II) with respect to the longitudinal axis of the arm (I), wherein the working unit ( 3 ) is able to be actuated by a second control member ( 4 b ) of the control members ( 4 a - 4 c ) according to at least one specific rotational movement ( 14 ) of the tool ( 6 ) about the direction of inclination (II), and wherein actuation of said second control member 4 ( b ) activates a specific rotation motor housed in the control body ( 10 ) which drives the working unit ( 3 ) to provide the tool ( 6 ) with the specific rotational movement ( 14 ) about the direction of inclination (II).
