摘要：
A suction instrument includes a grip portion and a cannula. The grip portion includes a suction port and defines a first lumen. The cannula extends distally from the grip portion. The cannula defines a second lumen in fluid communication with the first lumen of the grip portion. The cannula includes a proximal portion and a distal portion. The proximal portion of the cannula defines a first portion of the second lumen. The first portion of the second lumen has a first cross-sectional area. The distal portion terminates into an open distal end. The distal portion of the cannula defines a second portion of the second lumen. The second portion of the second lumen has a second cross-sectional area. The second cross-sectional area is smaller than the first cross-sectional area.
