PROBLEM TO BE SOLVED: To provide instruments that can reduce an initial installation cost and a management cost after the installation.SOLUTION: Minimally invasive surgical instruments of the present invention include: an elongated shaft having a predetermined length; an adjustment handle manually controllable by a user; a pitch direction operation part and a yaw direction operation part disposed in one end of the shaft and transmitting the movement in the pitch and yaw directions generated by the operation of the adjustment handle, respectively; a pitch direction actuating part and a yaw direction actuating part disposed at the other end of the shaft, and actuated in response to the operation from the pitch direction operation part and the yaw direction operation part, respectively; an end effector controllable by the pitch direction actuating part and the yaw direction actuating part; and multiple cables for transmitting the operations from the pitch direction operation part and the yaw direction operation part to the pitch direction actuating part and the yaw direction actuating part, respectively. The pitch direction operation part and the yaw direction operation part operate along the directions perpendicular to each other. |
