む状態に先端部本体１ａに取り付けられる。The tightening ring 6 of the balloon 5 has a wire diameter
It is formed to be slightly thinner, and the wheel diameter is formed smaller than the diameter of the entire circumferential groove 4. Therefore, as shown in FIG. 1, the fastening rings 6 at both ends of the balloon 5 are fitted into the entire circumferential grooves 4, respectively. The balloon 5 is attached to the distal end body 1a so as to surround the ultrasonic probe 3.
