DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an ultrasonic diagnostic device that is inserted endoscopically to perform ultrasonic diagnosis inside a body cavity. [Prior Art] An ultrasonic diagnostic device is a catheter that is inserted into a body cavity, etc., and has a rigid distal end at the distal end, and an ultrasonic transmitter/receiver attached to the rigid distal end. When inspecting and diagnosing the inside of a body cavity using a device, there is one in which a catheter is guided endoscopically into the body cavity using an endoscope. That is, the catheter is inserted into the treatment instrument insertion channel of the endoscope, the rigid tip part is led out from the treatment instrument lead-out part, and the catheter is monitored by the endoscope.
The ultrasonic transmitter/receiver is pressed against the vaginal wall of the body cavity, so that ultrasonic waves are directed into the body and the reflected echoes are received. Here, in an ultrasonic diagnostic apparatus, in order to prevent attenuation of ultrasonic waves, the ultrasonic transmitter/receiver must be firmly brought into close contact with the wall of the body cavity. However, the ultrasonic transmitter/receiver is provided on one side of the rigid tip part, and when observed through the observation window of the endoscope, it may be possible to observe only the back side of the ultrasonic transmitter/receiver of the catheter. In some cases, it may not be possible to confirm the exact location of this ultrasonic transceiver. For this purpose, catheters have been known in which a display section is disposed on the back side of the position where the ultrasonic transceiver is disposed in the rigid distal end portion of the catheter. [Problems to be Solved by the Invention] Incidentally, as an observation system of an endoscope, an extremely wide-angle objective lens is used in order to enable observation of as wide a range as possible. Further, the ultrasonic transmitter/receiver is generally disposed at the position closest to the distal end of the rigid distal portion. Moreover, the ultrasonic diagnostic apparatus has an extremely small diameter, for example, 3 mm or less, because it is inserted into a treatment instrument insertion channel of an endoscope. In view of the above, when the display section is provided on the back side of the ultrasonic transmitter/receiver, there is a problem in that it becomes extremely difficult to observe the display section. The present invention has been made in view of the above-mentioned problem, and its object is to provide an ultrasonic diagnostic apparatus that displays the direction in which an ultrasonic transmitter/receiver is arranged in an extremely easy-to-see manner. It is about providing. [Means for Solving the Problems 1] In order to achieve the above-mentioned objects, the present invention displays the directionality of the ultrasonic transceiver at least at the base of the rigid tip portion where the ultrasonic transceiver is disposed. Its feature is that it has a structure in which a mark is provided. [Function] By arranging the mark at the base of the rigid tip, the position of the ultrasonic transmitter/receiver can be detected extremely easily when observing this mark with the observation system of the endoscope. You will be able to do this. Therefore, the ultrasonic transceiver can be reliably brought into close contact with the region to be observed, and ultrasonic waves can be transmitted and received. [Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. First, in FIG. 2, 1 indicates an endoscope and 10 indicates an ultrasonic diagnostic device. The endoscope 1 includes an insertion section 2 inserted into a body cavity or the like, a main body operation section 3 connected to the proximal end of the insertion section 2, and a universal cord 4 connected to the main body operation section 3. The universal cord 4 is connected to a processor 5 incorporating a light source device and an image signal processing device. The distal end of the insertion section 2 contains CO.
A solid-state imaging device consisting of D, etc. is built-in, and the solid-state imaging device converts an optical image inside the body cavity into an electrical signal and sends it from the insertion section 2 through the main body operation section 3 and the universal coat 4 in order into the processor 4. The signal is transmitted, processed by the processor 4, and then displayed on the monitor device 6. The ultrasonic diagnostic apparatus 10 is as shown in FIG. It is inserted endoscopically into a body cavity, and the treatment instrument insertion channel 7 of the endoscope 1 is used for this purpose. This treatment instrument insertion channel 7 is installed inside the insertion section 2, and one end thereof is connected to a treatment instrument introduction section 7a provided in a continuous section between the insertion section 2 and the main body operation section 3, and the other end is connected to the illumination window 8.
and observation window 9, are connected to a treatment instrument lead-out section 7b provided at the distal end of the insertion section 2. The ultrasonic diagnostic apparatus 10 includes a catheter 11 that is inserted into a treatment instrument insertion channel 7, a control unit 12 that includes a driving means 12a and an encoder 12b including a laucoupinion mechanism and the like at the proximal end of the catheter 11, and a cable. 13
An ultrasonic signal processing device 14 is connected to the end of the cable 13. The ultrasound image signal-processed by the ultrasound signal processing device 14 can be displayed by the ultrasound monitor device 15. Most of the catheter 11 is a flexible part 11a, and the distal end of the flexible part 11a has a swivel joint part 11b or a swivel joint part 11a.
A hard tip portion 11c is successively connected to b. The ultrasonic transmitter/receiver 16 is attached to a flat portion provided on one side of the rigid tip portion 11c, and the ultrasonic transmitter/receiver 16 is
The swivel joint portion 11b allows it to be oriented in any direction of 360' as indicated by the arrow in FIG. Therefore, the insertion section 2 of the endoscope 1 is inserted into the body cavity, and its distal end is guided to the site where ultrasonic diagnosis is to be performed. Then, the catheter 11 of the ultrasonic diagnostic apparatus 10 is inserted into the treatment instrument insertion channel 7 from the treatment instrument introduction part 7a, and is led out by a predetermined amount from the treatment instrument delivery part 7b. In this state, the ultrasonic transmitter/receiver 16 provided on the rigid distal end portion 11c of the catheter 11
is brought into contact with the location where ultrasonic waves are to be transmitted and received, and the catheter 11 is pushed out in the direction shown by the arrow or moved in the opposite direction. During this time, ultrasonic waves are transmitted from the ultrasonic transceiver 16 into the body, and the reflected echoes thereof are received. The received signal of this reflected echo is transmitted to the ultrasonic signal processing device 14 together with a signal related to the position of the ultrasonic transceiver 16 output from the encoder 12b built in the control unit 12, and a predetermined signal is processed. Ultrasonic images can be displayed on the monitor device 5. Here, the ultrasonic transceiver 16 must be moved along the body cavity wall while being in close contact with the body cavity wall. If the ultrasonic transmitter/receiver 16 is far from the body cavity wall, the attenuation of the ultrasonic waves will be extremely large, and reflected echoes will not be received. Therefore, it must be possible to confirm that the ultrasonic transceiver 16 is accurately brought into contact with the body cavity wall. Therefore, as shown in FIG. 4, this ultrasonic transceiver 1
When the ultrasonic transmitter/receiver 6 contacts the vaginal wall while facing toward the observation window 9, check whether the ultrasonic transmitter/receiver [6] is in close contact with the vaginal wall through the observation window 9. Can be done. However, as shown in FIG. 5, when the back side of the ultrasound transmitter/receiver 16 faces the observation window 9, it is necessary to check whether the ultrasound transmitter/receiver 16 is in close contact with the vaginal wall. It cannot be done. Therefore, in the present invention, as shown in FIG. 1, on the surface of the rigid distal end portion 11c of the catheter 11 opposite to the placement position of the ultrasonic transceiver 16, from the root to the distal end. A linear mark 17 is drawn. Therefore, the position of the ultrasonic transmitter/receiver 16 can be confirmed using this mark 17 as a clue. Here, in order to obtain an image of the inside of the body cavity through the observation window 9 of the endoscope 1 with as wide a viewing angle as possible, the objective lens provided in the observation window 9 is extremely narrow. A wide-angle one is used. Therefore, the image displayed on the monitor device 6 becomes as shown in FIG. 6, where the root portion of the catheter 11 within the field of view is displayed with a certain degree of thickness, but it becomes significantly smaller toward the distal end portion. In addition, the catheter 11 itself is connected to the treatment instrument insertion channel 7.
For example, 3II
It has an extremely small diameter of 1 m or less. For this reason, depending on the position where the mark 17 is applied, it becomes extremely difficult to confirm the mark 17. Therefore, as described above, the root portion of the rigid tip portion 11c of the catheter 11, that is, the swivel joint portion 11
By forming the mark 17 linearly from the position connected to b toward the tip, it becomes extremely easy to confirm the mark 17. Moreover, when the mark 17 becomes easier to see in this way, its line width can be narrowed. Therefore, the position of the ultrasonic transceiver [6] can be displayed more accurately. As a result, when performing ultrasound diagnosis with the ultrasound transmitter/receiver 16 facing away from the observation window 9, ultrasound can be transmitted and received while the ultrasound transmitter/receiver 16 is firmly in contact with the vaginal wall. Ultrasound diagnosis can now be performed efficiently,
Moreover, it can be done with high precision. Next, FIG. 7 and FIG. 8 show a second embodiment of the present invention, and in this embodiment, the configuration is such that ultrasonic diagnosis is performed with four ultrasonic diagnostic neck devices 20 inserted into the body. It shows what was done. By inserting one into the body in this way, it is possible to transmit and receive ultrasonic waves at a position close to the lesion, etc., while avoiding areas that significantly attenuate ultrasonic waves such as fat layers. You will be able to obtain information regarding accurate ultrasound diagnosis. The rigid distal end portion 21c of the catheter 21 is formed to be long to some extent, and the proximal end portion of the rigid distal end portion 21c must be positioned within the treatment instrument insertion channel 7. And this tip hard part 21
The tip portion c is in a sharp state, and the ultrasonic transmitter/receiver 2z is provided at a position near this tip portion. In this case, as shown in FIG.
A linear 7-mark 23 is applied over the entire part 1c, and a scale 23a is formed from the parenthesis mark 23 from the tip side. If the mark 23 is formed in this way, the hard tip portion 21c
The direction of the ultrasonic transmitter/receiver 22 can be recognized even when the ultrasonic transmitter/receiver 22 is inserted into the body and even when the ultrasonic transceiver 22 is inserted to an arbitrary depth. Moreover, the insertion depth of the ultrasonic transmitter/receiver 22 can be recognized by the scale 23a, and the accuracy of ultrasonic diagnosis is significantly improved. [Effects of the Invention] As explained above, in the present invention, the mark indicating the directionality of the ultrasonic transmitter/receiver surface travels from at least the base of the hard tip portion toward the tip side. The direction of the ultrasonic transceiver installed at the tip of the hard part can be detected extremely accurately, and ultrasonic waves can be transmitted and received with the ultrasonic transceiver surface directed toward the area to be observed. You will be able to do it.
