PURPOSE:To prevent interference of a medical curing needle with a gantry during regulation of a high angle by a method wherein the medical curing needle is deviated from a straight line for intercoupling a holder base and the rotation center thereof, and the needle is held to a holding part in a state that the piercing tip of the needle is pointed to the rotation center. CONSTITUTION:Since a stationary shaft 4 is formed such that the outer size is made equal to the outer size of a holder body, the stationary shaft can be reliably secured to a holder base 69 by means of a lock screw 72. By mounting the holder body 1 to the holder base 29, the axis of a medical curing needle mounted to an arm 3 by means of a fixing screw 18 is inclined at 30 deg. with the mounting center of the holder base 69. Thus, when the position of the mounting center of the holder base 69 is set in a state to be inclined at, for example, 30 deg. with the central axis of a moving frame, the medical curing needle itself is inclined at 60 deg. with the central axis. Further, when the position of the holder base 69 is set on the central axis of the moving frame, the axis of the medical curing needle is inclined at 30 deg. with the central axis, and through movement of the holder base, the medical curing needle can be positioned on the central axis. |
