The invention relates to a manipulator (1) for minimally invasive surgical operation comprising a main arm (2) having: • a proximal end (3) equipped with a control interface (3a) and • a distal end (3b) insertable into the patient's body (4), the distal end (3b) carrying a controlled manipulation head (6) whose movements are controlled via the control interface (3a), the controlled manipulation head (6) comprising: ○ a base (17) hinged pivotally about a pivot axis (P) perpendicular to the longitudinal axis (II) of the main arm (2), ○ a gripper (7) comprising a first and a second gripping end (8, 9) having respective gripping surfaces (8a, 9a), the gripping ends (8, 9) being articulated about an articulation axis (10) between an open position and at least one gripping position, the gripper gripping (7) being rotatably mounted on the base (17) about an axis of rotation (R). The gripping surface (9a) of the first gripping end (9) of the gripper (7) defines at least two bearing lines (L1, L2) and the gripping surface (8a) of the second end of gripping means defines at least one opposite bearing line (L3) which is arranged in a plane (H) perpendicular to the hinge axis of the gripper (7), said perpendicular plane (H) containing the line of opposed support (L3) lying between said two bearing lines (L1, L2) of the first gripping end, and in that at least one gripping end has at least one angular positioning relief of a needle suture relative to the axis of rotation.L'invention concerne un manipulateur (1) pour opération de chirurgie mini-invasive comportant un bras principal (2) présentant : • une extrémité proximale (3) équipée d'une interface de commande (3a) et • une extrémité distale (3b) insérable dans le corps du patient (4), l'extrémité distale (3b) portant une tête de manipulation commandée (6) dont les mouvements sont commandés par l'intermédiaire de l'interface de commande (3a), la tête de manipulation commandée (6) comprenant : ○ une embase (17) articulée de faç
