Abstract: A holding device is a holding device that holds the medical device, and includes an arm configured to have a holder, which holds the medical device, at a distal end, a base configured to rotatably support the arm by a first joint, a disk attached to the arm, and a brake attached to the base and configured to press the disk, in which a distance between a center of rotation of the disk and a region where the brake presses the disk is changed depending on a rotation angle of the first joint.

Abstract: A medical manipulator including an insertion portion, where the insertion section including a bending portion and an end effector disposed on a distal end side of the insertion portion. The medical manipulator further including an actuator configured to generate a first drive force for moving the bending portion; a lever configured to generate a second drive force for moving the bending portion, the lever being used to move the bending portion instead of the actuator; a wire configured to transmit the first drive force or the second drive force to the bending portion; and a transmission blocking device configured to switch from the first drive force to the second drive force.

Abstract: A joint ring includes a main body part and a pair of protrusion parts protruding from a first surface of the main body part in a direction of a central axis thereof and having spherical surfaces on protruding portions. The main body part includes a pair of engagement holes and a pair of receiving holes. The protrusion parts include engagement parts which are configured to be capable of being inserted into the engagement holes. When the joint rings are arranged in the direction of the central axis and the protrusion parts of a first joint ring enter the receiving holes of a second joint ring, the spherical surfaces come into contact with receiving surfaces inside the receiving holes, and the first joint ring and the second joint ring become rotatable relative to each other with a line segment connecting centers of the respective spherical surfaces as a rotational center.
