摘要：
A multipurpose tissue sampling device is provided for extracting at least one tissue sample from a tissue sampling site. An outer sheath has a cutting surface and an outer sheath lumen extending from an outer sheath proximal end to an outer sheath distal end. An inner stylet has a solid inner stylet cutting tip, sampling notch, and an inner stylet lumen extending from an inner stylet proximal end to the sampling notch. The inner stylet exterior wall is configured to pass through the outer sheath lumen. A fine needle aspiration needle has an FNA needle body configured to pass through the inner stylet lumen. The FNA needle has an FNA needle lumen and a sampling feature. An actuator has a proximal port and a distal port with inner port walls that are configured to accept at least a portion of at least one of the outer sheath and inner stylet.
