PUNCTURE APPARATUS

摘要

A puncture apparatus includes a puncture needle that punctures biological tissues; a longitudinal-shaped vaginal insertion member that is inserted into the vagina; a guiding member; an interlock member for interlocking the vaginal insertion member with the guiding member; an ultrasonic probe that is provided in a distal portion of the vaginal insertion member to transmit and receive ultrasonic waves; and an ultrasonic marker that is provided in the guiding member to be able to recognize an ultrasonic image which is obtained from the ultrasonic waves transmitted and received from the ultrasonic probe. The interlock member has a through-hole into which the puncture needle is inserted, and the through-hole is a supporting portion that movably supports the puncture needle to guide the distal end of the puncture needle to the ultrasonic marker.

1. A puncture apparatus comprising:
a puncture needle configured to puncture biological tissues; a longitudinal-shaped vaginal insertion member configured for insertion into a vagina of a living being; a guiding member; interlock means for interlocking the vaginal insertion member with the guiding member; an ultrasonic probe that is provided on one side of either a distal portion of the vaginal insertion member or the guiding member to transmit and receive ultrasonic waves; an ultrasonic marker that is provided on the other side of either the distal portion of the vaginal insertion member or the guiding member to be able to recognize an ultrasonic image which is obtained from the ultrasonic waves transmitted and received from the ultrasonic probe; and supporting means for movably supporting the puncture needle to guide the distal end of the puncture needle from a side of the ultrasonic probe toward the ultrasonic marker.
