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.
Claims20
A surgical rongeur, comprising:
- a lower shaft having a proximal end and a distal end, wherein the lower shaft defines a floor including a trap door disposed proximate to the distal end of the lower shaft, and wherein the lower shaft terminates in a static footplate at the distal end of the lower shaft;
- an upper shaft having a proximal end and a distal end, the upper shaft slidably coupled to a top surface of the lower shaft, wherein the upper shaft terminates in a cutting blade at the distal end of the upper shaft;
- an elongated member slidably coupled along the floor of the lower shaft, the elongated member having a proximal end and a distal end, wherein the elongated member terminates in a sliding footplate at the distal end of the elongated member;
- a primary trigger coupled to the proximal end of the upper shaft, wherein actuation of the primary trigger is configured to alternately move the cutting blade between an open position and a closed position;
- and
- a secondary trigger coupled to the proximal end of the elongated member, wherein 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.
A dual-chamber rongeur for selectively saving or discarding human tissue, comprising:
- a main body portion having a first footplate at a distal end of the main body portion and an actuatable valve disposed proximate to the first footplate;
- a first chamber slidably coupled to a top surface of the main body portion, the first chamber further coupled to a first trigger adapted to move the first chamber into and out of a cutting position;
- a second chamber coupled to a bottom surface of the main body portion;
- and
- a second footplate slidably coupled within the main body portion, the second footplate further coupled to a second trigger adapted to move the second footplate into one of a plurality of positions to perform the selectively saving or discarding the human tissue.
A method, comprising:
- providing a rongeur, wherein the rongeur comprises:
- a lower shaft including a static footplate at a distal end of the lower shaft, the lower shaft defining a floor including a trap door disposed proximate to the distal end of the lower shaft;
- an upper shaft including a cutting blade at a distal end of the upper shaft, the upper shaft slidably coupled to a top surface of the lower shaft;
- a waste chamber coupled to a bottom surface of the lower shaft;
- a sliding member slidably coupled along the floor of the lower shaft, the sliding member including a sliding footplate at a distal end of the sliding member;
- a primary trigger coupled to a proximal end of the upper shaft;
- and
- a secondary trigger coupled to a proximal end of the sliding member;
- actuating the primary trigger to move the cutting blade into a closed position to cut out a tissue sample;
- and
- while the cutting blade is in the closed position, actuating the secondary trigger to retract the sliding footplate into a first position to discard the tissue sample or into a second position to save the tissue sample.
