摘要
An endoscopic needle for collecting tissue, cell and/or fluid specimens from a patient that uses a multi-channel connector having a first channel for accepting a vacuum source that will fluidly connect with a hollow needle at the distal end, and a second channel for receiving a stylet therein, an outer sheath having proximal and distal ends with the proximal end being operatively connected to a lower portion of a leur-lock, an inner tube fluidly connected to the multi-channel connector and an outer needle assembly connected to or as part of the inner tube, an inner needle or a stylet having a proximal end attached to a cap removably connected to the second channel, the stylet having a distal end connected to an inner needle or slidingly positioned within the outer needle, and a fluid pathway from the multi-channel connector to the interior of the outer needle.
