Abstract:
1. An instrument for use with an endoscope, the instrument comprising: an elongate section configured to move exterior to the endoscope, the elongate section including a distal end and a proximal end; an end effector attached to the distal end of the elongate section; an actuation device attached to the proximal end of the elongate section, the actuation device being configured to operate the end effector; and a guiding member integral with and immovable relative to the elongate section, the guiding member being configured to slidably encircle an external surface of the endoscope to permit the guiding member to move along a longitudinal axis of the endoscope, the guiding member being integral with the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope; wherein the guiding member is configured to interface with a feature on the external surface of the endoscope to stop the movement of the guiding member along the longitudinal axis of the endoscope.
