2. Description of the Related Art As an intrabody cavity ultrasonic diagnostic apparatus for obtaining ultrasound signal images of organs within a body cavity, those shown in FIGS. 1 and 2 have been proposed. In these figures, reference numeral 1 denotes an ultrasonic probe head, which has a window 2 for transmitting and receiving ultrasonic signals formed on its side, and a small diameter shaft 4 connected to the rear via a curved portion 3. There is a cord for transmitting and receiving ultrasonic signals, a wire for driving the mirror inside the ultrasonic probe head 1, etc. (not shown).
Built-in. This shaft body 4 passes through the channel of the insertion section 6 in which the optical viewing tube 5 is disposed,
The rear end portion is connected to a drive portion 9 via an optical viewing tube proximal portion 7 and a channel insertion port 8 . A light guide cable 10 is attached to the optical viewing tube proximal portion 7.
and an eyepiece section 11 that is inclined with respect to the axial direction of the insertion section 6 are connected. Further, the drive section 9 has a grip handle 12 connected to its lower side, through which a signal cable 13 is inserted, and a drive motor 14 connected to its rear.

In the above-mentioned ultrasound diagnostic apparatus, in order to obtain an ultrasound image, the insertion section 6 and the ultrasound probe head 1 are inserted into a body cavity, and a predetermined organ is captured within the field of view of the optical tube 5 in the insertion section 6. Ultrasonic probe head 1 at 15
The ultrasonic probe head 1 is brought into contact with the organ 15 by pressing the ultrasonic probe head 1 into contact with the organ 15 by bending the curved portion 3 as shown in FIG.

However, in the conventional device described above, the drive section 9 and the motor 14 are attached to the gripping handle 12, making it relatively large and heavy, and the insertion section 6 is relatively large and heavy.
Also, it is difficult to insert the ultrasound probe 1 into a body cavity, bend the curved portion 3, or bring it into contact with the organ 15. Further, since the signal cable 13 connected to the grip handle 12 is connected below the grip handle 12, when the insertion portion 6 is inserted to diagnose a deep organ, the inclination of the insertion portion 6 becomes large. There was a problem in that the connecting protruding side of the signal cable 13 came into contact with the body wall, making it difficult to operate.

This idea was made in view of the above-mentioned points, and in addition to making the grasping grip small and lightweight, the drive cable can be connected to the side of the grasping grip, so that the insertion part can be inserted into the body cavity especially for diagnosing deep organs. Even when the insertion section is tilted to a large extent, the protruding side of the drive cable connection does not come into contact with the body wall, which prevents the insertion section and the ultrasound probe head from being inserted into the body cavity or coming into contact with organs. It is an object of the present invention to provide an intrabody cavity ultrasonic diagnostic device that is easy to operate and further facilitates connection between the drive shaft of a grip and the drive shaft of a drive cable.

The curved direction of the curved portion 24 is set in the visual field direction of the endoscope 27 as shown in FIG. The ultrasonic transmitting/receiving window 22 is configured to fit within the field of view of the mirror 27. In this way, in the case of the one for intra-abdominal organ diagnosis shown in the figure, the endoscope 27 inserted into the insertion section 21
The reason why the visual field direction and the curved direction of the curved portion 24 are set to the right when viewed from the operator is that when used for ultrasound diagnosis of the intra-abdominal organ 49, it is necessary to determine which part of the skin has many blood vessels and the organ. The position of the organ is determined naturally, and the insertion position and insertion direction are medically determined. This is because it is suitable for operation and observation within a body cavity, such as observation of the ultrasound probe head 23 and close contact of the ultrasound probe head 23 to an organ. Therefore, for ultrasonic diagnosis of organs other than intra-abdominal organs, the viewing direction of the endoscope 27 and
It is a matter of course that the direction of curvature does not have to be to the right. Further, the ultrasonic transmitting/receiving window 22 provided in the ultrasonic probe head 23 is arranged in the viewing direction of the endoscope 27, that is, in order to visually confirm which part the window 22 is in contact with when the bending section 24 is bent. It is arranged at a position perpendicular to the direction.

In such a configuration, as shown in FIG. 11, the operator grasps the grip 29 with one hand and also places his or her thumb on the bending operation lever 31 of the approximately spherical bending operation part 30 formed on the head of the grip 29. The insertion section 21 is inserted into a body cavity, for example, the abdominal cavity, with the abdomen of the patient being applied, through a trocar (not shown). While observing the insertion section 21 diagonally forward to the right, insert the ultrasound probe head 2.
3 to the organ 49. After confirming the organ 49, the user operates the bending operation lever 31 with the thumb, indexes the operation wire 48, and moves the bending portion 24 in the viewing direction of the endoscope 27 for intraperitoneal diagnosis as shown in the figure. The ultrasound probe head 23 and the ultrasound transmitting/receiving window 22 are curved to the right as viewed from the operator's view, and the ultrasound probe is placed in the field of view, as shown in FIG. Transmission/reception window 22
is brought into close contact with a predetermined part of the organ 49.

As described above, the endoscope 27 faces the cutout window 25 formed on the side of the insertion section 21 behind the curved section 24, and its tip is of a perspective type, so that the field of view is limited to the ultrasound probe head 21. , the ultrasound probe head 23 can be curved in the direction of the field of view of the endoscope 27, allowing the ultrasound probe to be inserted while viewing the organ without being obstructed by the curved portion 24. This can be done while visually confirming both the probe head 23, and the diagnosis can be made accurately and easily.
Furthermore, it is also possible to check which position the ultrasonic wave transmitting/receiving window 22 is in contact with.

As mentioned above, according to this invention, the grasping grip can be made small and lightweight, and the drive cable can be connected laterally to the grasping grip, so it is particularly useful when the insertion part is inserted into a body cavity to diagnose deep organs. Even if the inclination of the insertion part becomes large, the protruding side of the drive cable connection does not come into contact with the body wall, making it easy to insert the insertion part and the head of the ultrasound probe into the body cavity and to make contact with organs. In addition, there is an effect that the connection structure between the drive shaft of the grip and the drive shaft of the drive cable can be easily configured.
