ABSTRACT:
A biopsy specimen gathering system has been developed which includes a biopsy needle having an aspirating chamber operatively coupled thereto. An elongated tubular sleeve forming a sleeve guard is provided, the sleeve guard having a closed base and an open top with the inner periphery of the upper end of the sleeve having a surface for sealingly engaging the outer periphery of the base of the aspirating chamber. The outer circumference of the shank of the sleeve guard has a plurality of spaced-apart circumferential grooves formed therein to provide spaced score grooves to a depth sufficient to permit the shank to be broken upon flexure thereof, thereby leaving an open ended sleeve firmly attached to the aspirating chamber and exposing a desired length of the tubular needle.
