Abstract:

A biopsy device is disclosed that comprises a cutting element mounted to a handpiece and a vacuum chamber. The cutting element comprises a stylet assembly and an outer cannula assembly. The stylet assembly includes a stylet that includes an open proximal end and a tissue opening at a distal end thereof. The tissue receiving opening is in communication with a lumen extending through the stylet. The outer cannula assembly includes an outer cannula that is slidably mounted over the stylet and has an open distal end with a cutting edge formed thereon. The vacuum chamber is in communication with the lumen of the stylet. The stylet is selectively advanced distally outwardly with respect to outer cannula to expose the tissue opening to targeted tissue. The outer cannula is selectively advanced over the tissue opening to sever tissue, while vacuum is generated in the vacuum chamber and delivered to the tissue opening through the lumen. The vacuum causes tissue to be drawn into and maintained in the tissue opening while the outer cannula severs tissue to obtain a biopsy core.
