Claims

[Scope of utility model registration request]

An outer sleeve whose posture is supported by a gimbal mechanism connected to a scanning drive head, an inner sleeve which is slidably inserted in the outer sleeve in the axial direction and is biased by a spring toward the subject, and the inner sleeve. The end face of the two sleeves has a column-shaped deep wound body in which an ultrasonic transmitter/receiver which is inserted so as to be movable in the axial direction and is biased toward the subject by a spring is housed in the end face on the subject side. The posture between the deep wound body and the subject is maintained by a plurality of guide legs provided on each of the sides, and a notch formed on the entire inner circumference of the end of the inner sleeve on the subject side; ,
A couplant consisting of a liquid guide part that communicates with this notch and a cap provided on the side opposite to the subject, and an oil-impregnated ring made of a porous elastic body provided in the notch and fixed to the inner surface of the inner sleeve. 1. An ultrasonic deep wound device, characterized in that it is equipped with a deep wound device guide leg that is attached to the deep wound main body side of the notch portion and has a protrusion corresponding to a contact gap on the subject side.
