Abstract
A surgical rongeur includes a lower shaft that defines a floor including a trap door, the lower shaft terminates in a static footplate. An upper shaft is slidably coupled to a top surface of the lower shaft, the upper shaft terminates in a cutting blade. An elongated member is slidably coupled along the floor of the lower shaft and terminates in a sliding footplate. A primary trigger is coupled to the upper shaft, where actuation of the primary trigger is configured to alternately move the cutting blade between an open position and a closed position. A secondary trigger is coupled to the elongated member, where actuation of the secondary trigger, while the cutting blade is in the closed position, is configured to retract the sliding footplate from the static footplate into one of a plurality of positions.
