Patent number: 9066745Abstract: A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member to simultaneously rotate and translate the cutting member in response to a force applied to the drive. A method of cutting tissue includes positioning an outer member such that tissue is located within the outer member, engaging the tissue with an inner member, and simultaneously rotating and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut the tissue. The inner member is mechanically driven to undergo simultaneous rotation and translation.Type: GrantFiled: February 11, 2015Date of Patent: June 30, 2015Assignee: Smith & Nephew, Inc.Inventors: Peter M. Cesarini, Karen Drucker, Rafal Jezierski, Roger R. Cassidy, Jr.

Patent number: 7510563Abstract: A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member. The drive may include a drive member having a helical groove and being attached to the cutting member. Furthermore, the drive may include an inner drive hub coupled to the drive member such that the drive member rotates with the inner drive hub while being free to translate relative to the inner drive hub. The drive simultaneously rotates and translates the cutting member in response to a force applied to the drive.Type: GrantFiled: December 13, 2002Date of Patent: March 31, 2009Assignee: Smith & Nephew, Inc.Inventors: Peter M Cesarini, Karen Drucker, Rafal Jezierski, Roger R. Cassidy, Jr.

Patent number: 6695816Abstract: A cannula includes a coupling interface adapted to receive and engage a wide variety of medical instruments having engaging portions which are different. In general, the cannula includes an elongated insertion member having a passage for receiving the medical instrument and a clamping assembly disposed at the proximal end of the elongated insertion member to engage the medical instrument. The clamping assembly includes a second surface axially spaced from the first surface of the elongated insertion member, and a biasing member positioned to bias at least one of the first surface and the second surface axially toward each other and to clamp an engaging portion of the medical instrument between the first and second surfaces.Type: GrantFiled: August 26, 2002Date of Patent: February 24, 2004Assignee: Smith & Nephew, Inc.Inventor: Roger R. Cassidy, Jr.
