Abstract

An activating mechanism for activating an endoscopic ligator is disclosed. The activating mechanism includes a mounting component and an activating component coupled thereto. The mounting component inserts directly into the operating channel of an endoscope and is dimensioned to maintain a friction fit within the operating channel to mount the mechanism to the endoscope. The mounting component includes a channel for receiving an activation line of the ligating device which is threaded through the operating channel and the channel in the mounting component, and onto the activating component of the activating mechanism. The activation line attaches to a spool of the activating component. The activating component further provides a drive pin and a roller clutch for setting the activating component in an engaged or a disengaged position and a knob for rotating the drive pin. When the drive pin is engaged with the roller clutch, the knob can only rotate in one direction. When the drive pin is in the disengaged position from the roller clutch, the knob can rotate in either direction.
