[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic probe, and more particularly to an ultrasonic probe used for a surgical operation using a laparoscope or the like.

[0002]

2. Description of the Related Art Conventionally, various types of ultrasonic probes have been devised, and various types have been developed depending on the type of operation.

[0003] Abdominal surgery such as cholecystectomy has conventionally been performed by laparotomy.
The burden on both the surgeon is large, especially for patients, there are problems such as prolonged operation time, pain after surgery, prolonged hospital stay, etc. Had problems.

[0004] In order to address the above problems, a surgical operation using a laparoscope, which is a type of endoscope, has been invented. This is typically four times on the patient's abdomen, as shown in FIG.
A hole is made in a place, four tubes (trocars) having an inner diameter of 0.5 to 1.2 cm are pierced, and a laparoscope 20 and a surgical tool 21 are inserted from the trocar to perform an operation.

Conventionally, a thin intraoperative ultrasonic probe which can be inserted into the trocar and directly touches the internal organs requires that the ultrasonic probe body has an elongated rod shape.
Required. And among such ultrasonic probes,
The elongated rod-shaped interior is made of metal, and the surface portion is made of resin.
While improving the rigidity of the ultrasonic probe body,
Temporary insulation is provided .

[0006]

The present invention is to provide a as described above Toraka
Observation of ultrasonic tomographic images during surgery using tools
Remove biological tissue from a specific part of the body
The need for smooth puncture under acoustic wave guidance
There is hope. However, an ultrasonic probe with an elongated shape
Using a puncture needle, perform a desired puncture operation in the body away from the fingertip.
It is very difficult to
It is very difficult to accurately guide the puncture needle to the desired position
There was a problem that it was difficult.

Therefore, the present invention can be inserted into a trocar.
Accordingly, an object of the present invention is to provide an ultrasonic probe that can smoothly use a puncture needle .

[0008]

[ MEANS FOR SOLVING THE PROBLEMS] The present invention is elongated and rod-shaped.
Shaped, pipe-shaped metal member on the outer periphery
A pipe-shaped resin member surrounding the member.
Attached to the ultrasonic diagnostic equipment,
An ultrasonic probe that transmits and receives ultrasonic waves, near the tip

[0009] Next, the second, the in the first configuration, visually bright the position of the puncture needle guide in the vicinity of the puncture needle guide or puncture needle guide portion in the ultrasonic probe
It is characterized in that is colored to identify the Akira.

[0010]

[Function] In the ultrasonic probe of the present invention, puncture is performed.
The puncture needle can be inserted along the needle guide.
Puncture process while confirming the puncture needle in the ultrasonic image
be able to. In addition, a clearly colored puncture needle guide is provided.
The needle to the elongated probe
Can be easily mounted and used .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings.
The ultrasonic probe A based on the present invention, as shown in FIG.
A vibrator 3 is attached to the case portion 1, and a cable portion 5 for the vibrator is inserted into the case portion 1. This ultrasonic probe A
Has a total length of about 400 mm and can be used for a trocar having an inner diameter of 10 mm. Conventionally, rod-shaped ones have been made with a transrectal probe or the like, but they are not suitable for trocars because their outer diameters do not match.

As shown in FIG . 1B, the case 1 constituting the outer peripheral portion of the probe A has a double structure of a metal pipe portion 9 located inside and a resin pipe portion 11 located outside. To
That have exhibited. The metal pipe section 9 is not connected to any other conductive parts. This is a so-called floating state.

In this embodiment, since the metal pipe portion 9 is provided on the outer peripheral portion of the probe, the strength of the ultrasonic probe can be increased, and the outside of the metal pipe portion 9 can be formed by a resin pipe. Since it is covered by the portion 11, electrical insulation can be maintained, and the influence of the leakage current on the living body can be prevented.

Further, the outer peripheral surface of the case portion 1 is a black, matte surface, and when the inside of the abdominal cavity is illuminated with illumination light of a laparoscope, light is reflected on the outer peripheral surface of the ultrasonic probe. It is possible to prevent the operation part from being difficult to observe with a laparoscope.

The tip of the ultrasonic probe A has
As shown in FIG. 2, a puncture needle guide is provided, and at the time of surgery or inspection using a laparoscope, a puncture needle is inserted along the puncture needle guide, and the puncture needle is confirmed while confirming the puncture needle with an ultrasonic image. Inspection can be performed.

FIG. 2 shows the shape and mounting position of the puncture needle guide.
As shown in FIG. 2A, there is a case where a groove-shaped puncture needle guide 13a is provided at the tip of the ultrasonic probe as shown in FIG.
As shown in (b), the puncture needle guide 13b having a hole shape may be provided at the tip of the ultrasonic probe. In addition, as shown in (c), a groove-shaped puncture needle guide 13c is provided on the side, or (d).
There is also a method of providing a hole-shaped puncture needle guide 13d in the transducer portion of the ultrasonic probe as described above. Further, there is a method of providing a hole-shaped puncture needle guide 13e in the front part of the vibrator as shown in (e).

Further, as shown in FIG. 3, the vicinity of the puncture needle guide is colored or marked with a clear color such as red, yellow, white or the like, and a puncture needle guide mark is attached to the puncture needle guide to thereby perform a laparoscope. The position of the puncture needle guide can be easily and clearly confirmed below, and the puncture needle can be easily inserted through the puncture needle guide. Specifically, when the puncture needle guide mark is provided on the ultrasonic probe of FIG. 2A, the puncture needle guide mark 15a is provided as shown in FIG. When attaching a puncture needle guide mark to the ultrasonic probe, FIG.
When the puncture needle guide mark 15b is attached to the insertion end of the puncture needle guide as shown in (b) and the puncture needle guide mark is attached to the ultrasonic probe shown in FIG. 2 (c), FIG. As shown in ()), a puncture needle guide mark is attached to the case portion of the puncture needle guide 13c excluding the vibrator portion.

Further, as shown in FIG. 4, if an identification member such as a projection 17 is provided on the same side as the puncture needle guide 15a at the end near the cable section 5 of the ultrasonic probe, Even if the ultrasonic probe has a rod shape, the puncture needle guide 1
The direction in which 5a is located can be easily determined from outside the body, and the position of the puncture needle guide can be more easily confirmed. The identification member is not limited to the protrusion, and may be colored. Even when the puncture needle guide is not provided, if an identification member such as a protrusion is provided on the side where the transducer is attached, the orientation of the transducer can be easily determined even from outside the body, and ultrasonic diagnosis can be easily performed. be able to.

[0019]

[Effect of the Invention] The present invention is configured as described above, and the puncture needle
It becomes possible to insert a puncture needle along the guide part,
Performing puncture processing while recognizing the puncture needle in the ultrasonic image
Can be. Also, using a long probe and a long puncture needle,
Even a difficult puncture in the body away from the fingertip can be easily performed by providing a clearly colored puncture needle guide.
