[Prior Art] Conventionally, such an electronic scanning type intracorporeal ultrasonic diagnostic apparatus has been disclosed in JP-A-57-128126, JP-A-58-193905, and JP-B-60-37730. What is known is. In other words, this ultrasonic diagnostic apparatus arranges a plurality of ultrasonic probes composed of strip-shaped ultrasonic transducers side by side at the tip of the insertion part in the body cavity and operates them by a scanning circuit to generate an ultrasonic beam. By doing so, an ultrasonic diagnostic layer image inside the body cavity is obtained. By the way, in these intracorporeal ultrasonic diagnostic devices, the ultrasonic transducer is fixedly arranged at the distal end of the intracorporeal insertion part, and when the insertion position into the intracorporeal cavity is determined, the obtained ultrasonic diagnostic The layers were also decided uniquely.

[Problems to be Solved by the Invention] Therefore, in the conventional intracorporeal ultrasonic diagnostic apparatus, the ultrasonic diagnostic layer to be obtained is uniquely determined by the insertion position. When making a diagnosis, it was necessary to operate the insertion part over a wide range. Especially when the insertion site is in the shape of a narrow duct such as the esophagus or the large intestine, the wide-range operation as described above involves the operation of applying pressure or sliding contact to the inner wall of the duct. It had the drawback of causing great distress to the patient.

In addition, as an improvement measure, an ultrasonic probe consisting of ultrasonic transducers arranged in parallel on one plan view arranged at the tip of the insertion part in the body cavity is rotated on the same plan view. An ultrasonic diagnostic apparatus (see Japanese Patent Laid-Open Nos. 59-22534 and 60-176635) has been proposed.

However, in these ultrasonic diagnostic apparatuses, the ultrasonic probe can be rotated on the same plan view, but it must be rotated three-dimensionally so that diagnosis can be performed in a wide range in the insertion direction. Therefore, in the case of a lesion that is long in the insertion direction, it is difficult to detect the lesion, no improvement has been made in that respect, and the drawbacks have not yet been solved.

Therefore, an object of the present invention is to make an ultrasonic probe disposed at the distal end portion of the insertion part in the body cavity three-dimensionally oscillate with respect to the side surface of the insertion part to make the emitting direction of the ultrasonic wave variable and to insert the insertion part. It is an object of the present invention to provide an intracorporeal ultrasonic diagnostic apparatus capable of extremely easily obtaining an ultrasonic diagnostic layer image over a wide range in the insertion direction without moving any.

[Means and Actions for Solving Problems] In the present invention, in order to solve the problems in the conventional intracorporeal ultrasonic diagnostic apparatus described above, an opening is provided on the side surface of the distal end portion of the intracorporeal insertion portion, and the opening is formed. An electronic scanning type ultrasonic probe is attached and disposed on the swingable swinging member by an operation from outside the body cavity inside the section so that the scanning surface of the ultrasonic probe can be three-dimensionally changed. The present invention is characterized in that a target diagnosis portion can be diagnosed over a wide range without moving the insertion portion in the body cavity.
