Abstract

PURPOSE:To enhance the diagnosing efficiency for carrying out accurate diagnosis without causing the dislocation of the paracentetic position of a paracentetic needle. CONSTITUTION:A U-shaped groove 3 is provided to the scanning surface 2 of a probe 1, and an attachment 6 is fitted to the groove 3 so as to be inserted therein. The attachment 6 is fixed by a fixing member 5 that has been provided to the upper part of the probe 1. Thus, a paracentetic needle can be guided from the upper part of the probe 1 to the scanning surface 2 without being dislocated from the paracentetic position. Further, the fitting and removing of the probe 1 can be smoothly carried out, so that operability can be enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puncture probe used for biopsy examination, and more particularly to a puncture probe suitable for guiding a puncture needle.

[0002]

2. Description of the Related Art A biopsy test is one in which a puncture needle is inserted into a diagnosis site to take out tissue or body fluid from an organ in the body and use this for diagnosis or the like. In this case, an ultrasonic tomographic image of a predetermined area of the body is displayed so that the puncture needle is not accidentally punctured in another place when a predetermined tissue in the body is collected, and a probe dedicated to puncture is used. I'm using it.

In the conventional puncture probe, as shown in FIGS. 3 and 4, a U-shaped groove 16 is formed so as to penetrate from the upper part of the probe 7 to the scanning surface. The puncture needle 11 was passed through. Further, the attachment 10 for stabilizing the puncture needle 11 is provided with an adhesive or a screw 1.
The attachment 10 is attached to the upper part of the probe 7 by means of a guide 5, a guide portion 12 for guiding the puncture needle 11, a support portion 13 provided with a groove 14 in which the guide portion 12 is movable in an arc shape, and a guide. It was composed of a fixing portion 17 for fixing the portion 12 at an arbitrary position of the groove 14. When changing the puncture angle, the fixing portion 17 was loosened, the guide portion 12 was moved in the groove 14, and the fixing portion 17 was tightened at the desired position.

[0004]

In the above-mentioned prior art, the puncture needle is guided by the attachment only before the U-shaped groove, and the puncture needle outlet of the guide portion and the body insertion position are separated from each other. Therefore, the puncture needle may be displaced in the groove. Further, the conventional puncture probe provided with a groove is only a linear probe, and when performing puncture with the convex probe, the puncture needle was pierced from the outside of the scanning surface. I could not observe near the body surface.

Further, the attachment work of the attachment by the screw is complicated for the operator, and when the attachment is directly attached, the above-mentioned disinfection work becomes more difficult.

From the above, an object of the present invention is to improve the diagnosis efficiency by performing accurate diagnosis without shifting the insertion position of the puncture needle.

[0007]

In order to achieve the above-mentioned object, the present invention provides an ultrasonic electroacoustic conversion section comprising a probe element, a plurality of acoustic matching layers, an acoustic lens, and a backing material, and an electroacoustic conversion section for the ultrasonic wave. In an ultrasonic probe configured to have a case that houses the acoustic conversion unit and a coaxial multicore cable that connects the probe element and the ultrasonic transmission / reception unit, parallel to the long-side direction of the electroacoustic conversion unit. A U-shaped groove is provided in the groove, a puncture attachment that guides the puncture needle to the electroacoustic transducer is fitted in the groove without a gap, and a fixing member that fixes the puncture attachment to the upper portion of the groove is provided. It is provided.

[0008]

A U-shaped groove is provided so as to penetrate from the upper portion of the probe to the electroacoustic conversion section, and the puncture needle is guided to the electroacoustic conversion section by fitting the attachment in this groove. Further, the fixing member attached to the upper portion of the probe fits with the side surface of the attachment to fix the attachment.

As a result, the puncture needle will not be displaced from the insertion position, and the attachment,
It can be easily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a front view, a side view, and a bottom view of a convex probe with an attachment attached. The convex probe 1 of this embodiment is L-shaped, and the scanning surface 2 is arranged so as to have an arc shape.
A U-shaped groove 3 parallel to the long side of the probe is provided so as to vertically penetrate from the scanning surface 2 to the upper portion of the probe 1. Also, U
A case 4 containing a cable for connecting the probe 1 and the ultrasonic apparatus main body is provided above the scanning surface 2 without the groove 3, and the probe 1 is scanned by holding the case 4 portion. U-shaped groove 3
A fixing member 5 for fixing the attachment 6 from the side surface is provided on the upper part of the.

A dedicated puncture attachment 6 is attached to the U-shaped groove 3. This attachment 6
The part that enters the U-shaped groove 3 is thin, and the U-shaped groove 3 is fitted so as to fill the inside of the groove 3. The portion located above the probe 1 is thick so that it can be easily held when it is attached and detached, and the side surface is provided with a recess into which the fixing member 5 fits. In addition, the attachment 6 is provided with a guide hole for a puncture needle that can handle a plurality of puncture angles (usually three types of 0 °, 15 °, and 30 °).

When the attachment 6 is attached to the probe 1, the attachment 6 is slid along the U-shaped groove 3 and is moved until the fixing member 5 enters the recess.
The attachment 6 is fixed to the probe 1. Conversely, when removing the attachment 6 from the probe 1, the fixing member 5
The attachment 6 can be easily removed by pressing the attachment 6 to the extent that it separates from the depression and pulling it out in this state.

As described above, since the convex probe 1 is provided with the U-shaped groove 3 and the attachment 6 fitted in the groove 3 is attached, the conventional puncture needle is inserted from the outside of the scanning surface. It can be inserted through the U-shaped groove 3 provided on the scanning surface 2, and puncture near the body surface can be performed. Further, since the attachment 6 is located from the upper part of the probe 1 to the vicinity of the scanning surface 2, the puncture needle can be guided from the upper part of the probe 1 to the scanning surface 2 and is not displaced from the puncturing position.

Furthermore, by inserting the fixing member 5 attached to the upper portion of the probe 1 into the recess provided on the side surface of the attachment 6, the attachment 6 can be easily fixed to the probe 1 and the attachment 6 can be removed. Since it can be done by pulling it out while pressing it, the puncture work can be performed smoothly and the operability is improved.

Although the attachment of the attachment to the convex type ultrasonic probe has been described in the present embodiment,
By changing the shape of the portion of the attachment that fits into the U-shaped groove, it is possible to attach the attachment of this embodiment to a sector-type ultrasonic probe or another probe.

[0016]

According to the present invention, the probe is provided with a U-shaped groove, an attachment is attached to this groove, and the puncture needle is guided from the upper portion of the probe to the vicinity of the scanning surface. The blurring of the puncture needle can be eliminated. Further, the attachment can be fixed by fitting the fixing member on the upper part of the probe into the recess provided on the side surface of the attachment, and further, the removal is performed only by holding the attachment, so that the operability is improved.
