A biopsy device having a cutting element is disclosed. The cutting element includes an inner cannula having a tissue receiving aperture disposed proximate a distal end thereof and an inner lumen. The inner cannula is slidably disposed within the inner lumen of an outer cannula. A vacuum chamber is disposed about at least a portion of the cutting element and is configured to create a vacuum in the cutting element during a biopsy procedure. The inner cannula is advanced distally outwardly and to cause the vacuum to be generated in the vacuum chamber. The vacuum is delivered to the cutting element whereby tissue is drawn into the tissue receiving aperture. The outer cannula is advanced distally outwardly after the inner cannula such that tissue drawn into the tissue cutting aperture is severed.

Vacuum assisted biopsy needle set

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.

Vacuum assisted biopsy device

A pneumatic coupling is provided. The pneumatic coupling is configured to couple a plurality of pneumatic lines together. According to the preferred embodiment of the present disclosure, the pneumatic coupling includes first and second housings and a plurality of fittings sized to receive the pneumatic lines.
