| 摘要 |
A supporting structure for a ligating band dispensing device adapted to be coupled to a distal end of an endoscope comprises a rigid substantially cylindrical, transparent outer support surface adapted to receive a plurality of ligating bands thereon, wherein the support surface includes a distal portion extending from a distal end thereof proximally to a distal-most ligating band receiving area. A channel extends axially through the support surface from the distal end to a proximal end thereof, wherein an abutting surface is formed along at least a portion of a circumference of the channel to define a distal-most point of penetration of an endoscope received therein. A gripping surface extending around at least a portion of a circumference of the proximal end of the channel is sized so that, when an endoscope extends into the proximal end of the channel, the gripping surface frictionally couples the support surface to the endoscope.
