    • 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.
    • 超声探头位于限定在外壳中的腔室中,以插入到被检体的体腔内。 驱动轴连接到探头以传递旋转力,并且为此通过超声诊断装置的插入部分的通道联接到驱动源。 提供第一密封构件用于阻挡腔室和通道的一端之间的连通,设置第二密封构件用于密封引导构件的通道的另一端,并且设置旁路连通通道以使通道 与房间通信。 提供一个打开/关闭阀,用于打开和关闭连通通道,超声波传送介质通过该连通通道被填充在腔室中,并且插入通道的通道。 在填充操作完成后,通信通道被阻塞。

    • In an endoscope apparatus, an ultrasonic vibrating element is rotatably arranged at a distal end of a flexible inserting portion, this ultrasonic vibrating element is rotated by a motor provided in a subsidiary operating portion via a flexible cable extended through the inserting portion, the distal end portion of the inserting portion is bent by operating a handle provided on a primary operating portion, which is arranged at the proximal side of the subsidiary operating portion; a forceps channel is extended through the inserting portion and an opening of the forceps channel is formed in the subsidiary portion. According to such structure, the forceps can be inserted in the forceps channel easily and existing forceps having a standard length can be used as they are.
    • 在内窥镜装置中,超声波振动元件可旋转地布置在柔性插入部分的远端处,该超声波振动元件通过设置在辅助操作部分中的电动机通过延伸穿过插入部分的柔性电缆旋转, 通过操作设置在辅助操作部分的近侧的主操作部分上的手柄来弯曲插入部分的部分; 镊子通道延伸穿过插入部分,镊子通道的开口形成在辅助部分中。 根据这样的结构,可以容易地将镊子插入镊子通道中,并且可以直接使用具有标准长度的现有镊子。
