Abstract
A surgical instrument includes a hub, a rotating member, an impeller, and an impeller enclosure. The hub has a proximal portion and a distal portion and defines a lumen therebetween. The distal portion of the hub includes a sleeve portion configured to rotatably support the rotating member. The rotating member extends through the hub and has a proximal end and a distal end. The proximal end of the rotating member is configured to couple to an external driving mechanism. The impeller is coupled to the distal end of the rotating member and is configured to accelerate fluid flowing into or out of the lumen. The impeller enclosure is coupled to the distal portion of the hub and defines an impeller volume around the impeller. One or more openings are defined around the sleeve portion of the hub such that the lumen is in fluid communication with the impeller volume.
