An accessory device for an endoscope includes a cap attached to a shaft of the endoscope, the cap extending along a first axis, a first tip coupled to the cap and movable relative to the cap between a deployed configuration and a non-deployed configuration, and a first shaft defining a lumen and extending proximally from the first tip. In the deployed configuration, the first tip extends along a second axis that is offset from the first axis, and in the non-deployed configuration, the first tip extends along a third axis that is offset from the first axis.
