A supporting structure (2) for a ligating band dispensing device adapted to be coupled to a distal end of an endoscope (6), comprises a rigid substantially cylindrical transparent outer support surface (30) adapted to receive a plurality of ligating bands (4) thereon. The support surface includes a distal portion extending from a distal end (14) thereof proximally to a distal most ligating band receiving area. A channel (3) extends axially through the support surface from the distal end to a proximal end thereof. 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 te proximal end of the channel the gripping surface frictionally couples the support surface to the endoscope. |
