ABSTRACT:
An ultrasonic probe for puncture treatments is constructed in a manner that a guide member, for guiding a puncture needle, is provided on a side surface of an ultrasonic probe of a linear scanning type, with a needle being positioned by the guide member to be movable at right angles to the surface of the body of a patient, and a beam of ultrasonic wave is emitted by the probe in a direction oblique to the length dimension of the needle. The probe may be positioned obliquely to the needle, in which case, an acoustic coupling member of a wedge shape is inserted in the gap formed between the emitting end of the probe and the body. Alternatively, the probe may be positioned parallel with the needle in which case a wedge shaped member capable of deflecting the ultrasonic waves, is placed on the emitting end of the probe, and a wedge shaped acoustic coupling member is connected to the deflecting member so as to deflect the ultrasonic waves to be oblique to the needle within the body. The needle may be an acupuncture needle, a cannula, a tube, or the like.
