Medical manipulator

A medical manipulator comprising:

• an elongated flexible inserted portion;
• an end effector disposed at a distal end of the inserted portion;
• an operation portion that is disposed at a proximal end of the inserted portion and with which the end effector is operated;
• a first wire in which one end thereof is secured to the end effector and that transmits a motive force of the operation portion to the end effector;
• a long coil that is formed from a material having a greater rigidity than the inserted portion and in which one end thereof in a longitudinal direction is secured to the end effector and the other end thereof in the longitudinal direction is secured to the operation portion;
• and
• a reinforcement tube having a greater bending rigidity than the long coil,
• wherein the operation portion includes a first spherical housing that is connected to the inserted portion, a second spherical housing that is relatively rotatable with respect to the first spherical housing centered on a prescribed center point, and an end-effector operating member that is secured to the other end of the first wire and with which the first wire is pushed/pulled in the longitudinal direction,
• the long coil is disposed at a position at which the long coil covers an area surrounding the first wire,
• the reinforcement tube is disposed at a position at which the reinforcement tube covers an area surrounding the long coil in spaces in the first spherical housing and the second spherical housing,
• the first spherical housing includes a tubular tube support portion that supports the reinforcement tube,
• the tube support portion has a support portion inner hole into which the reinforcement tube is inserted, a bonding hole that passes therethrough in a radial direction via the support portion inner hole, and a bonding clearance portion that passes therethrough in the radial direction via the support portion inner hole,
• the bonding clearance portion is disposed between the bonding hole and openings of the reinforcement tube, the openings being located in an outer surface of the reinforcement tube at intermediate positions in the longitudinal direction, and
• the reinforcement tube is secured to the support portion inner hole by an adhesive configured to flow thereinto from the bonding hole.
