ABSTRACT:
A method for obtaining a biopsy uses an instrument assembly which includes an elongate tubular member having a distal end portion defining a specimen-receiving chamber, the instrument assembly being provided at a distal end with a cutting blade extending in a plane oriented substantially transversely with respect to the tubular member. The distal end portion of the tubular member is inserted into organic tissues of a patient so that some of the tissues enter the chamber. Upon sufficient insertion of the distal end portion of the tubular member into the organic tissues of the patient, the blade is moved in the transverse plane to thereby sever the tissues in the chamber from tissues outside the chamber. Upon shifting of the blade to sever the tissues in the specimen-receiving chamber, the distal end portion of the tubular member is removed from the patient, together with the severed tissue sample.
