PROBLEM TO BE SOLVED: To provide a puncture needle by which piercing is safely and surely executed through the use of a general ultrasonic probe. SOLUTION: The holder is constituted of a holder part 50 where the probe 80 is loosened and inserted and a clip part 52 which pressurizes its arms 56a and 56b by elastic force from an external part and is brought into pressure contact with the side surface of the probe 80. The arms 56 of the holder part 50 are brought into pressure contact with the probe 80 by externally fitting the clip part 52 to the arms 56a and 56b of the holder part 50 in spite of a little difference in the size of the probe 80 to be inserted to the holder part 50. Thus, the puncture needle holder constituted by the holder part 50 and the clip part 52 is fixed to the probe 80. The puncture needle holder is fitted to the outside of the probe so as to be freely attachable/detachable so that a probe itself is not required to be the special one for piercing. |
