ABSTRACT:
The present invention provides a tissue resection device comprising a handle housing having a fluid infusion lumen. A shaft is reciprocatably mounted to the housing, the shaft having an aperture adjacent to a distal end and a fluid and tissue aspiration lumen extending from the aperture to a proximal end of the shaft. A cutting member is disposed adjacent to the aperture to sever tissue as the shaft is reciprocated, and an imaging mechanism on the housing is oriented toward the cutting member, thereby allowing the attending surgeon to optically direct the removal of body cavity tissue. A chopping mechanism is disposed within the lumen of the shaft to reduce the size of tissues passing through the lumen.
