摘要：
A device and method of using the device to access a desired tissue site within a patients body and separating a tissue specimen from the tissue site suitable for evaluation. The device includes a probe member having an arcuate tissue-cutting RF powered electrode secured to and distally spaced from the distal end of the probe and a small dimensioned distal extremity which when an inner lumen thereof is subjected to a vacuum, secured tissue for the specimen to the surface of the distal extremity. A circular tissue-cutting blade preferably secured to the distal end of a supporting tube is configured to rotate and move longitudinally along the shaft of the probe member effective to sever a tissue specimen from tissue secured to the surface of the distal extremity of the probe member. The supporting tube covers the separated specimen, and may be disposed within an accessing cannula.
