METHOD AND DEVICE FOR TISSUE RESECTION

摘要

A tissue resection device for preferred use in an organ inflated with non-conductive optically transparent fluid under pressure is disclosed. The instrument includes a rigid shaft (P) having a proximal end, a distal end, and defining a perfusion lumen (25) extending therebetween. At its distal end, the shaft (P) is provided with a rounded blunt end having an elongate aperture exposing the lumen near the distal end. A drive tube (30) is rotatably disposed within the shaft lumen and has a proximal end, a distal end, and a drive tube aspiration lumen extending therebetween. A cutting head (C) is mounted on the distal end of the drive tube and has a laterally disposed cutting edge which can resection either by conventional cutting or electrocautery.
