An endoscopic instrument includes an outer cannula and an inner cannula disposed within the outer cannula, a tool channel, a retractable tool, and a retractable tool actuator. The tool channel is defined within a radial wall of the outer cannula or positioned adjacent to the radial wall of the outer cannula. The retractable tool includes a distal tip and sized to fit within the tool channel The retractable tool actuator is configured to move, responsive to actuation of the retractable tool actuator, the retractable tool along the tool channel from a first position in which the distal tip of the retractable tool is within the tool channel to a second position in which the distal tip of the retractable tool extends beyond a distal end of the outer cannula
