ができる。There is a method of performing ultrasound-guided puncture of deep organs using an ultrasound diagnostic device that uses an ultrasound scanner to perform ultrasound diagnosis by applying ultrasound to the external surface of the human body, but it is necessary to insert the puncture needle deeper. However, the resolution of ultrasonic tomographic images is also poor, which is dangerous. Therefore, if an ultrasound-guided puncture is performed from within the body cavity using an ultrasound endoscope, the puncture can be guided using a high-resolution ultrasound tomographic image. Furthermore, since the puncture depth can be shallow, safe and reliable puncturing can be performed.

た。Furthermore, conventionally, two endoscopes were inserted into the Φ person at the same time and puncture was performed by protruding the puncture needle from one endoscope and inserting it into the needle of the other endoscope. A device has been proposed. (Unexamined Japanese Patent Publication No. 60-75026) [Problems to be solved by the invention] However, in the conventionally proposed devices, two endoscopes are inserted at the same time, which causes pain to the patient during insertion. It was very difficult to guide the puncture needle from the other endoscope to the guide hole provided in one endoscope.

。そして、この状態で体腔内に挿入部３を挿入する。Next, the operation of the above-mentioned intrabody cavity ultrasonic diagnostic apparatus will be explained. First, when inserting the insertion section 3 of the intrabody cavity ultrasound scanner 1 into a body cavity, the puncture needle guide 11 moves its tube body 17 on the slide operation section 24 as shown in FIGS. 1 and 2. (By this, the tip is stored in the storage section 16. In other words, in order to rotate the side surface of the erection member 22 by pulling it into the tip opening 13 until it hits the stopper surface 29a, the tip ends in the bottom surface of the storage section 16, i.e., It fits tightly against the back surface of the acoustic probe 14 without popping out.The field of view of the puncture needle guide 11 faces forward of the insertion section 3.In this state, the insertion section 3 is inserted into the body cavity.

して超音波探触子１４の走査範囲Ｓの部位側を向く。After inserting the insertion section 3 into a wide space within the body cavity, for example, into the stomach, when performing ultrasound diagnosis, the tube body 17 of the puncture needle guide 11 is pushed through the slide operation section 24 on the proximal side. As a result, the tip of the tube body 17 moves forward while pushing the construction member 22 and leaves the storage section 16. However, since the tip of the tube body 17 is connected to the construction member 22, it rotates around its two rotation centers at a constant rate. Rotate while keeping your distance. The distal end portion of the tube body 17 is pushed out from the distal end opening 13 of the insertion channel 2 to form a loop shape, and the side surface of the construction member 22 is pushed out from the distal end opening 13 of the insertion channel 2.
Rotate until it hits 9b. Then, this tip is reversed and faces toward the region within the scanning range S of the ultrasound probe 14.
