摘要： An ultrasound probe is located in a chamber defined in a housing to be inserted into a body cavity of a subject. A drive shaft is connected to the probe to transmit a rotational force and, for this purpose, is coupled to a drive source via a passage of an insertion section of an ultrasound diagnostic apparatus. A first sealing member is provided for blocking a communication between the chamber and one end of the passage, a second sealing member is provided for sealing the other end of the passage of the guide member, and a bypass communication passage is provided for enabling the passage to communicate with the chamber. An opening/closing valve is provided for opening and closing the communication passage via which an ultrasound transmitting medium is filled in the chamber and the passage of the insertion passage. The communication passage is blocked after the filling operation has been done.

摘要： On the side at hand of an optical probe, a whole rotation transfer connector rotates while being supported by a ball bearing and a slide bearing and, therefore, rotation is transferred to a flexible shaft. The relative position between the flexible shaft and an optical sheath is changed in accordance with the amount of screwing of a sheath stopping member on the side at hand into an outer cylinder by an external thread portion and an internal thread portion. When the optical sheath is moved furthermore, the flexible shaft is elongated due to elastic deformation because the length of the flexible shaft is regulated by the interval between a locking part of a locking member at the tip and a shaft stopping member. A tip housing is made to contact with the locking member while tension is applied to the flexible shaft by the rear end surface in the direction of the side at hand. During the use of optical probe, even when the optical probe is curved and the inner surface of the flexible shaft is contacted with the inner surface of the optical sheath, moving of the tip housing is canceled by the elongation amount of the flexible shaft elongated in advance and, therefore, the tip housing rotates at a constant position relative to the probe longitudinal direction on all occasions.

摘要： An ultrasonic diagnostic apparatus including an ultrasonic vibrating element, a rotator for rotating the ultrasonic vibrating element, an illuminating window and an observing window arranged in a side wall of an inserting portion. The apparatus is so arranged that the center axis of the inserting portion is deviated from that of the rotator with respect to the radial direction but the center of curvature of a cover window surrounding the rotator is coincident with the center axis of the rotator. Therefore, a uniform resolving power can be obtained in all directions into which the ultrasonic wave is transmitted. Then an ultrasonic image without undesired artificates is displayed on a screen of a monitor and the outer diameter of the inserting portion can be made small.
