ABSTRACT:
An apparatus and method for acquiring biopsy specimens includes an outer cannula having a bevelled distal end and an opposing proximal end having a Luer-type fitting. A stylet having a like bevelled distal end is inserted within the outer cannula before the cannula is placed within the patient. Following placement of the outer cannula, the stylet is removed, and a biopsy actuator equipped with a biopsy needle is then inserted within the proximal end of the cannula. The distal tip of the biopsy needle is provided with a specimen retaining notch. The biopsy actuator includes a mating Luer-type fitting that is releasably attached to the proximal end of the cannula. The biopsy actuator includes a spring-loaded trigger mechanism for advancing the distal end of the biopsy needle to expose the specimen retaining notch, and thereafter rapidly advances the distal end of the cannula to cut tissue prolapsed within the notch. The Luer fittings are then disengaged, the biopsy actuator is withdrawn, and a second specimen may then be taken by inserting a second biopsy actuator in a like manner.
