Abstract

Disclosed herein is an endoscopic surgical assembly having improved cutting efficiency. In particular, the present invention provides an endoscopic shaver assembly configured for automated axial as well as rotational motion so as to enhance tissue resection.

Description

[0001] priority [0002] [0001] This application claims the benefit of U.S. Provisional Application Serial No. 60 / 831,986, filed July 19, 2006, and U.S. Patent Application Serial No. 11 / 634,102, filed December 6, 2006, the contents of which It is hereby incorporated by reference in its entirety. technical field [0003] [0002] The present invention relates generally to the field of endoscopic tissue resection and powered surgical instruments for use therein. More particularly, the present invention relates to a minimally invasive endoscopic cutting instrument having an elongated inner member that is axially slidable and rotatably disposed within an elongated fixed outer member, both the inner member and the outer member At their ends there are cutting apertures which cooperate to excise tissue during endoscopic surgery. Background technique [0004] [0003] In contrast to traditional surgical procedures that require relatively large incisions to gain access to surgical site...
