Endoscopic band ligation devices

摘要

The present invention provides a ligating band dispenser is attached to the end of the endoscope. The ligating apparatus is configured to dispense multiple ligating band to the internal multiple sites of a patient. Retracted against the end of the endoscope in order to maintain visibility endoscopic, then ligating band is tubular to be expanded to define a suction chamber of the tissue suction band feed during navigation in it is supported on a carrier member of the band. It is slidable in the carrier member on the band, the band engages the individually extruded from the end of the band carrier them, the band driver tubular member advances to the treatment site that has been selected. One-handed operation control handle for selectively operating the movement of the hand the driver to release the band and extension band carrier is also provided, and is removably attached to and slidably mirror axis endoscope.
