Abstract
A nasal suction apparatus used during endoscopic sinus surgeries. The nasal suction apparatus includes a catheter having a proximal end and a distal end, with the catheter being closed on the distal end to focus suction through the sides of the catheter. The catheter includes first and second lumens extending parallel from the distal end to the proximal end, with the lumens being separated by an inner partition. Suction holes on the distal end of the catheter provide suction to the surgical site. A flexible tube is attached to the catheter to provide connection with a source of suction. A porous fabric cover is placed over the suction holes to prevent obstruction of the suction holes by solid debris such as blood clots and tissue fragments, while allowing for passage of air and liquid.
