Description

  The present invention relates to a puncture probe apparatus that is used when performing puncture under an ultrasonic diagnostic apparatus and includes a probe that transmits and receives ultrasonic waves and a guide portion that guides a puncture needle.

  Conventionally, a puncture needle such as an injection needle is inserted into a living body, an examination such as collection of a tissue such as a tumor, a local treatment of a drug, or a thermotherapy such as microwave or radio wave irradiation from a puncture needle, etc. A puncture is performed. Such puncture is generally performed by ultrasonic diagnosis in order to avoid blood vessels that may cause major bleeding due to damage or to reliably puncture a target tissue such as a tumor. This is performed while referring to a tomographic image generated by the apparatus. In this way, the puncture performed under the guidance of the ultrasonic diagnostic apparatus is called ultrasonic guided puncture.

  For example, when performing ultrasound-guided puncture, in order to ensure that the puncture needle is inserted into the target position, it is stable so that the puncture needle does not become blurred or disappear on the tomographic image. A method of attaching a puncture adapter for puncture to a probe of an ultrasonic diagnostic apparatus so as to be able to be inserted, and inserting a puncture needle supported by the puncture adapter into a living body from the vicinity of an end of a probe surface which is a living body contact surface (For example, refer to Patent Document 1).

  However, when performing ultrasound-guided puncture, the probe transmits / receives ultrasound to / from the subject and depicts the lesion with a tomographic image, and then inserts the puncture needle into the body. Even if this puncture adapter is used, since the human body is flexible, the body surface is deformed into a concave shape by the acting force required for the insertion of the puncture needle. Then, the inside of the body is also deformed according to the deformation, so that the position of the internal organ changes. On the other hand, due to deformation of the body surface by the puncture needle, the probe may become unstable with respect to the subject, and the tomographic image may become unclear. In this case, the probe is more strongly covered so that the tomographic image becomes clear. Since it is pressed against the specimen, the position of the internal organ changes further. This change in position is particularly noticeable in a hard part (for example, a cirrhosis part).

  Therefore, the operator moves the ultrasonic probe while responding to changes in the position of the puncture needle and the target affected area, and further adjusts the direction of insertion of the puncture needle, and punctures the target affected area. Will enter. For this reason, the insertion work may take a long time. Also, by moving the probe so as not to lose sight of the affected area, the image of the puncture needle may become unclear, and the puncture needle may be inserted without noticing a large blood vessel or the like, which may cause health damage to the human body. Do not wipe.

  Therefore, for the purpose of enabling accurate ultrasound-guided puncture, the portion where the puncture needle is inserted is aspirated so that the relative position between the target affected portion position and the puncture needle insertion position is fixed. A puncture device that performs ultrasonic guided puncture has been proposed (see, for example, Patent Document 2).

  However, since the suction direction is opposite to the insertion direction, the body surface of the insertion portion is still deformed into a concave shape by the insertion, and the internal organ moves due to the deformation. In addition, due to the structure for suction, there is a problem that the apparatus becomes large and the convenience is lost.

The connection cable 10c is connected to an ultrasonic diagnostic apparatus (not shown). Further, a concave portion 10ba is provided in the side surface portion 10b of the ultrasonic probe 10, and is used for mounting the puncture adapter 1.

  The puncture adapter 1 has a cylindrical attachment / detachment portion 1a for detachably attaching the puncture adapter 1 to the ultrasonic probe 10 and a guide for guiding the puncture needle N onto the ultrasonic scanning line by the ultrasonic probe 10. Part 1h. Further, the attaching / detaching portion 1a includes an opening 1c for inserting the probe surface 10a and the protruding portion 10d of the ultrasonic probe 10, and the probe surface 10a and the protruding portion 10d of the ultrasonic probe 10 inserted into the opening 1c. And a planar portion 1 f that substantially coincides with the probe surface 10 a of the ultrasonic probe 10 and extends in the same direction (however, a direction orthogonal to the scanning direction of ultrasonic waves by the ultrasonic probe 10). 1h, when the probe surface 10a of the ultrasonic probe 10 is inserted into the opening 1c, it substantially coincides with the probe surface 10a of the ultrasonic probe 10 and spreads in the same direction (however, the ultrasonic scan direction). A flat portion 1g having a puncture needle N, which penetrates the flat portion 1g and guides the puncture needle N so as to be defined on an ultrasonic scanning line by the ultrasonic probe 10; It is constructed and a hole 1d configured in capacity (guide hole).

  Further, the inner surface 1aa of the detachable portion 1a of the puncture adapter 1 is provided with a convex portion 1ab that engages with the concave portion 10ba provided in the side surface portion 10b of the ultrasonic probe 10, and the ultrasonic probe in the opening portion 1c. When the ten probe surfaces 10a are inserted, the concave portion 10ba and the convex portion 1ab are engaged, whereby the ultrasonic probe puncture adapter 1 is detachably attached to the ultrasonic probe 10, and the ultrasonic wave The probe surface 10a of the probe 10 and the flat surface portion 1f and flat surface portion 1g of the ultrasonic probe puncture adapter 1 are substantially coincident with each other.

Even if the puncture needle N presses the surface of the subject P, the surface of the subject P at that position is already formed by the protrusion 10d. Since it is deformed into a concave shape and tension is applied, the puncture needle N does not further deform. Therefore, since there is almost no deformation of the surface of the subject P at the time of insertion, that is, the tumor or the like does not move at the time of insertion, the operator refers to the tomographic image and more accurately the puncture needle N. Can be inserted into the target position. Further, since the insertion direction of the puncture needle N is directed from the outside of the probe surface 10a toward the probe surface 10a, the protrusion 10d is moved in the direction of the probe surface 10a so as to deform the surface of the subject P in the direction in which the puncture needle N is pressed.
