Patent number: 8931388Abstract: A cutting tool includes an outer tubular member having a first magnet and an inner tubular member having a second magnet wherein the inner tubular member is slidably disposed within the outer tubular member. A force, such as an attractive or opposing force, is created between the first magnet and the second magnet. The attractive or opposing force creates a preload force between the inner tubular member and the outer tubular member or a hand piece that is engaged with the inner tubular member. A method of creating a force between an inner and outer tubular member is also disclosed.Type: GrantFiled: December 5, 2006Date of Patent: January 13, 2015Assignee: Smith & Nephew, Inc.Inventor: Rafal Z. Jezierski

Publication number: 20140140815Abstract: 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: ApplicationFiled: November 20, 2012Publication date: May 22, 2014Applicant: SMITH & NEPHEW, INC.Inventors: Cemal Shener-Irmakoglu, Brian J. Loreth, Rafal Z. Jezierski, Paul Robert Duhamel

Publication number: 20140066965Abstract: 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: ApplicationFiled: November 4, 2013Publication date: March 6, 2014Applicant: Smith & Nephew, Inc.Inventors: Petter A. Hedstrom, Rafal Z. Jezierski, Kenneth W. Krause

Publication number: 20130072935Abstract: The present disclosure relates to an arthroscopic resection device. The device includes an outer member including a hub, an inner member including a hub, the inner member housed within the outer member, a tube coupled to the outer member, and means for allowing longitudinal movement of the outer member relative to the inner member, the means coupled to the tube. A method of tissue repair and other arthroscopic resection devices are also disclosed.Type: ApplicationFiled: February 15, 2012Publication date: March 21, 2013Applicant: Smith & Nephew, Inc.Inventors: Dean Matsuda, Victor Ilizaliturri-Sanchez, Mathew Erle Mitchell, Rafal Z.

Publication number: 20120253227Abstract: A medical device that includes an outer tube assembly that includes a straight outer tube, an inner tube assembly that includes a straight inner tube disposed within the outer tube, and at least one interference member on the outer tube assembly and at least one interference member on the inner tube assembly. The inner tube and the outer tube are configured to rotate relative to each other to resect tissue at a distal end of the inner and outer tubes. The interference members are configured to prevent a force exerted along a longitudinal axis of the inner tube from separating the inner and outer tubes without rendering the medical device unusable.Type: ApplicationFiled: March 30, 2011Publication date: October 4, 2012Applicant: SMITH & NEPHEW, INC.Inventors: Cemal Shener-Irmakoglu, Rafal Z.
