PURPOSE:To reduce fatigue due to the use of an ultrasonic probe and to improve the operability of the ultrasonic probe by providing holding auxiliary tool so as to from a shape wherein its one terminal is engaged with a rotary ring and its other terminal is hung on a finger holding the ultrasonic probe. CONSTITUTION:A ring groove 12A is the one in which the rotary ring 16 is fitted. Part of the rotary ring 16 is cut so as to be fitted in the ring groove 12A, and also, the mating part 16a of a cut part is formed obliquely against a ring axial direction so as to rotate the rotary ring 16 smoothly. A projection 16b is formed at the rotary ring 16, and furthermore, a hole 16c to engage a finger hanging means is formed at the projection 16b. The finger hanging means is comprised of, for example, a finger hanging strap 18 with flexibility. The finger hanging strap 18 comprises cloth or a leather material, and the length of the strap is formed in length so as to be hung on the thumb holding the ultrasonic probe. |
