A manipulator comprises a hollow shaft, wires provided on the shaft and a working unit disposed on one end of the shaft and being driven by at least one wire of the wires, the working unit having a tip tool including a rolling mechanism which rotates about an axis Or directed to a distal end thereof. A tip side surface of a proximal end member and a cover of a distal end member are relatively rotated by the rolling mechanism. The cover has a rotation identifier for indicating a degree of relative rotation of the tip side surface. The tip side surface has an alignment indicator for indicating an initial position of the cover.

Manipulator for medical use

A medical manipulator comprises a distal end working unit including a gripper as an end effector, an operating unit for operating the distal end working unit, a coupling interconnecting the distal end working unit and the operating unit, and an attitude changing mechanism for changing an attitude of the distal end working unit. When the operating unit is operated by an operator, the end effector is mechanically operated by a transmitting member. The attitude changing mechanism is operated by a bending drive source and a rotational drive source, which are operated when the operating unit is operated by the operator.

A manipulator includes a hollow joint shaft, wires extending through the joint shaft, pulleys mounted on an end of the joint shaft, for imparting a drive force to the wires, a distal-end working unit mounted on another end of the joint shaft, for being actuated by the wires, and a sealing member for preventing liquid such as blood from flowing from the distal-end working unit through the joint shaft to a connector. The sealing member has holes defined therein, and the wires are slidably inserted through the holes.

Manipulator

In a manipulator, an actuator block contains motors and rotary shafts extending from the motors. A working unit of the manipulator contains a connecting portion, attachable to and detachable from the actuator block. The connecting portion has pulleys connectable to ends of the rotary shafts, and has a locking plate movable by alignment pins. The locking plate has slits, which are engaged with plate-shaped portions formed on the upper ends of the pulleys. A coil spring is placed between the locking plate and a top plate.

A manipulator includes a composite input unit that is manually operable by the fingers, a connector shaft extending from an operating unit, and a working unit mounted on the distal end of the connector shaft. The working unit comprises a rolling mechanism, a tilting mechanism, and an opening and closing mechanism. The composite input unit includes a shuttle ring for actuating the rolling mechanism. The manipulator also includes a gripper for gripping a curved needle. The gripper is placed near a DVC, whereupon the rolling mechanism is actuated to roll the gripper and to pierce a living body with the curved needle, until the point of the curved needle projects outside of the living body.
