PEN-SHAPED CELL- AND TISSUE-INSPECTION DEVICE FOR ULTRASONIC FINE NEEDLE

摘要

PROBLEM TO BE SOLVED: To improve operability and portability, and to correctly collect cells and/or tissues at the location of a lesion.;SOLUTION: A pen-shaped inspection device includes: a hollow body having a needle through-hole formed at the front end, and an opening formed at the rear end; a sliding part which is slidably placed inside the body; an elastic member which is placed in the body so as to provide an elastic force for returning the sliding part backward; a syringe wherein a needle is protruded from or inserted in the needle through-hole by longitudinal movement of the sliding part while a cylinder is attached to the front end of the sliding part; a rotation part which is provided between the sliding part and the body so as to rotate the syringe when the sliding part moves longitudinally; a head which is screwed with the rear end of the sliding part and pulled out from the body, so that a longitudinal traveling distance of the sliding part can be adjusted according to the length screwed with the sliding part; and a negative-pressure generator which is mounted in the body, and generates negative pressure in the syringe by pulling a piston of the syringe with a pressing force of a button located outside.;COPYRIGHT: (C)2013,JPO&INPIT
