DISPOSABLE BIOPSY DEVICES AND METHODS OF OBTAINING TISSUE BIOPSY SAMPLES USING SAME

摘要

A disposable biopsy device includes a vacuum generating assembly generating a vacuum. The disposable biopsy device also includes a tissue cutting assembly including a hollow outer needle having a longitudinal axis and an inner cutter needle positioned within the hollow outer needle. The tissue cutting assembly is pneumatically coupled to the vacuum assembly such that the vacuum drives a cutting motion of the inner cutter needle along the longitudinal axis of the hollow outer needle.
