Abstract

An endoscopic device is provided. The endoscopic device may comprise a distal end and a proximal end. The proximal end may be opposite the distal end. The endoscopic device may further comprise a handle at the proximal end and a tube extending from the handle towards the distal end of the endoscopic device. The endoscopic device may further comprise an accessory channel. The accessory channel may extend through the tube. The endoscopic device may further comprise a slide, the accessory channel extending through the slide, and a curved track disposed adjacent to the proximal end of the endoscopic device. The slide is movable within the curved track to cause movement of the accessory channel within the tube.
