Abstract
Disclosed herein is an aspiration assembly for attaching to an endoscope. The aspiration assembly comprises an extendable suction tube for aspirating an object (e.g., smoke, blood, blood clot, bone debris, or tissue debris) at or near a surgical site during an endoscopic surgery. The aspiration assembly can further comprise an irrigation tube for directing a fluid to the surgical site for cleaning the endoscope lens. By integrating an extendable suction tube with the endoscope, the technology described herein obviate the need for instrument switching and/or multiple surgeons during the surgery.
