Abstract
A surgical tool arrangement including a powered handpiece which cooperates with a combined electrosurgical and mechanical cutting instrument. The electrosurgical and mechanical cutting instrument includes an outer static housing element which defines an electrode for delivering electrical energy to the surgical site, and a cutting element disposed within the outer housing and movable relative thereto for manipulating patient tissue. The electrosurgical and mechanical cutting instrument is an integral component attachable to the surgical tool to provide multiple functions in a single instrument, such as cauterization, ablation and mechanical cutting, without the need for attachment of additional housing structures or other adapters. The tool arrangement also includes a universal handpiece which is capable of accepting and operating a number of different surgical instruments, each having one or multiple functions.
