Abstract
A powered tissue resection system for use during endoscopic surgical procedures in which a body cavity is filled with a gas medium to maintain pneumoperitoneum. A powered tissue resection device is utilized to simultaneously resect and aspirate tissue from the surgical work site within the gas-filled body cavity. Along with the aspirated tissue a portion of the ambient fluid medium is aspirated. A separating means is provided to separate the resected tissue and other debris from the fluid medium, generally carbon dioxide, and return the latter to the body cavity to maintain pneumoperitoneum.
