METHOD AND DEVICE FOR TISSUE RESECTION

摘要

The present invention provides a tissue resection device comprising a handle housing (208) having a fluid infusion lumen (228). A shaft is reciprocally 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 (202) is disposed adjacent to the aperture to sever tissue as the shaft is reciprocated, and an imaging mechanism (220) on the housing is oriented toward the cutting member (202), thereby allowing the attending surgeon to optically direct the removal of body cavity tissue. A chopping mechanism (206) is disposed within the lumen of the shaft to reduce the size of tissues passing through the lumen.
