Patent number: 9655640Abstract: A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.Type: GrantFiled: November 4, 2013Date of Patent: May 23, 2017Assignee: Smith & Nephew, Inc.Inventors: Petter A. Hedstrom, Rafal Z. Jezierski, Kenneth W. Krause

Patent number: 9546662Abstract: 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.Type: GrantFiled: November 20, 2012Date of Patent: January 17, 2017Assignee: Smith & Nephew, Inc.Inventors: Cemal Shener-Irmakoglu, Brian J.
