Hand-held manipulator with symmetrical grip

A manipulator comprising:

• a control unit (1) having a handle (4) capable of being held by one hand,
• at least one control member (4a-4c) 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 (2a) in which the control unit (1) with the handle (4) is mounted, and having a distal end (2b),
• a working unit (3) mounted on the distal end (2b) 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 (4a-4c) according to at least one degree of freedom of movement,
• in which:
• the handle (4) comprises a gripping portion (4e) 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 (2b) 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 (4a-4c) are shaped so as to be accessible about the handle (4) in an annular control area in the vicinity of one end (4f) of the gripping portion (4e), 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 (4a) of said control members (4a-4c) 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 (4b) of the control members (4a-4c) according to at least one specific rotational movement (14) of the tool (6) about the direction of inclination (II),
• 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), and
• wherein the actuation of said first control member (4a) controls an inclination actuator housed in a control body (10) which drives the working unit (3) to provide the tool (6) with the inclination movement (12).
