Abstract
A rongeur includes a device body having a first arm and a second arm slidably coupled to the first arm. A handle operatively coupled to the first arm and the second arm is configured to move the second arm along a length of the first arm in a first direction and an opposing second direction. A tip assembly is removably coupled to a distal end of the device body. The tip assembly includes a first tip and a second tip slidably coupled to the first tip. A locking mechanism is configured to removably couple the first tip to the first arm and removably couple the second tip to the second arm. The second tip is movable with respect to the first tip from an open position toward a closed position as the second arm moves in the first direction.
