Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an intrabody cavity probe, particularly for observing tumors in the uterine cervix.

[Technical background of the invention and its problems]

BACKGROUND ART Conventionally, a novel intrabody cavity probe that can be freely moved to a diagnostic site and capable of precise diagnosis has been highly acclaimed as an intrabody cavity probe for diagnosing cancer of the uterine cervix, lung cancer, and the like.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and provides a novel surface body cavity that can be attached to the fingertip and freely enter and exit the vagina, and that can contribute to precise diagnosis by accurately observing the necessary diagnosis site. The purpose is to provide probes.

[Overview of the invention]

To achieve the above object, the present invention generally includes a case that matches the shape of a fingertip, an ultrasonic transducer housed within the case, and a probe that is similar to the case and the ultrasonic transducer that is internally mounted on the fingertip. It is characterized by the fact that it is equipped with a fixing member for the purpose.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing an ultrasonic transducer used in the intracorporeal probe according to the present invention, and FIGS.
The figures are perspective views of the intracorporeal probe according to the present invention, showing the ultrasonic transducer housed in a case; FIG. 2 is a view from below, and FIG. 3 is a view from above.

Moreover, FIG. 4 is a perspective view showing a state in which the intracorporeal probe according to the present invention is attached to a fingertip.

In FIG. 1, an ultrasonic transducer 1 used in the present invention includes a backing material 2 as a sound absorbing member, an ultrasonic wave emitting surface, for example, an array-shaped piezoelectric ceramic 3, and an ultrasonic wave emitting surface provided on the ultrasonic emitting surface of the piezoelectric ceramic 3. It consists of an acoustic lens 4 and a flexible PC board 5 on which a conductive layer for drawing out electrodes from the piezoelectric ceramic 3 is printed.

Backing material 2. The piezoelectric ceramic 3 and the acoustic lens 4 are laminated and fixed using an adhesive such as a two-component epoxy adhesive. In addition, the flexible PC board 5 connects each element and the conductive layer by soldering from the side surface of the array-shaped piezoelectric ceramic 3, and bends above the backing material 2 to draw out the electrodes. It is connected to a power source (not shown) via a covered lead wire 5a connected to. Note that 6 is an insulating tube in which the covered lead wires 5a are bundled. The acoustic lens 4 is made of, for example, silicone rubber, has a function of increasing resolution, and comes into direct contact with a part of the body.

As shown in FIG. 2, the ultrasonic transducer 1 configured as described above is housed in a case 7 that is shaped to fit a finger.
The case members 7a and 7b, which are divided into halves along the dividing line X in the case 7, are combined and pressed so that a part of the acoustic lens 4 comes out into a hole 8 formed in the combined part. And case 7 and ultrasonic transducer 1
Fill the gap with case 7 with white silicone adhesive, for example.
The ultrasonic transducer 1 is fixed inside.

The other surface of the case 7 housing the ultrasonic transducer 1 thus completed (the surface opposite to the surface from which a portion of the acoustic lens 4 is exposed) is formed with a recess 9 on which a finger can be placed. There is.

Incidentally, the case 7 is formed of, for example, a rubber clay-like material (putty type).

When using the intracorporeal probe 10 configured as described above by attaching it to a finger, first
After adjusting the abdominal part of the probe 10- to the four parts 9, as shown in FIG. By inserting 10 together with a fingertip into the vagina, for example, the ultrasonic emission surface (the part where the acoustic lens comes out) of the sieve probe 1o can be freely moved to the area necessary for observing a tumor in the uterine cervix by moving the fingertip. This allows for precise diagnosis. Note that the fixing member is not necessarily bag-shaped, but may be a plurality of ring-shaped members such as rubber bands.

〔Effect of the invention〕

As explained above, the present invention has a shape that perfectly matches the fingertip and can be fixed to the fingertip, and the probe can be freely moved in and out of a narrow body cavity by the movement of the fingertip, so it can contribute to precise and minute diagnosis. An intracavity probe can be provided.
