Abstract
An arthroscopic or other medical device includes an elongate shaft having a proximal end and a working end. At least one electrode for treating tissue is located at the working end of the shaft, and a fluid outflow path extends proximally from the working end through a first channel portion in the shaft. A handpiece is coupled to the proximal end of the shaft and has a body with a second channel portion formed along an axis therein. The second channel is receives a heated or other outflow from a proximal end of the first channel in the shaft, and the second channel runs along an axis of the handpiece. A thin wall sleeve is located in the handpiece so that it surrounds at least a portion of the second channel. The thin wall sleeve is surrounded by an air gap or otherwise provides a thermal barrier between an exterior surface of the thin wall sleeve and an inner surface of the body of the handpiece in order to limit heat transfer from the heated or other fluid outflow through the second channel.
