PURPOSE:To prevent a protective tube from being caught in a tip edge of a tracurl by curving a curved part by operating a slender bar-like operating body and providing the protective tube in the curved part for varying a direction of a tip constituting part to which an ultrasonic vibrator, etc., are attached. CONSTITUTION:In an ultrasonic diagnostic device 1, an inserting part 4 extends from the tip side of an operating base body 2 having an operating part 3, and in its tip part, a tip constituting part 6 is provided through a curved part 5. From the rear end side of the operating base body 2, a signal cable 2a extends, and one end part thereof passes through the inside of the inserting part 4 and reaches the tip constituting part 6, and is connected to an ultrasonic vibrator 62. Also, in the inserting part 4, a pair of guide tubes 7a being parallel mutually are inserted through, an in its insides, an operating body 8a is inserted through, respectively. Also, in the inside of the curved part 5, a protective tube 65 whose rear end part and tip part are connected to the tip part of the inserting part, and the tip constituting part 6, respectively is provided, and in the guide tube 7a, the tip part is opened on the tip part surface of the inserting part 4 positioned on the outside of the protective tube 65. |
