Abstract: A surgical apparatus is provided for performing turbinate lateralization including a pair of levers connected at a fulcrum, each lever including a handle connected to a bend portion, a pair of shafts, each shaft connected to the bend portion of each of the levers on first side of the fulcrum, where each shaft is dilated laterally with a substantially parallel displacement along a shaft length in response to the pair of levers being brought together on a second side of the fulcrum; a limiter connected to the pair of levers and configured to limit a dilation of the pair of levers in response to the pair of levers being brought together on the second side of the fulcrum; and a limiting bridge configured to attach between the shafts at a predetermined distance from the distal end of each shaft and press against a columella of the patient.

Abstract: A guillotine surgical cutter. The cutter includes an inner sleeve that moves within the inner channel of an outer sleeve. The distal end of the outer sleeve may have a plurality of outer ports. The inner sleeve may also have an inner channel and one or more openings that are in fluid communication with the outer ports of the outer sleeve. The inner sleeve can be connected to a diaphragm and a disk spring. The diaphragm may be adjacent to a drive chamber that is coupled to a source of pressurized air by a control valve. Actuation of the control valve pressurizes the drive chamber and moves the inner sleeve relative to the outer sleeve. The cutter may include a snap spring that is attached to the disk spring and which provides an additional acceleration of the inner sleeve. The springs return the inner sleeve back to the original position when the control valve is switched to reduce the pressure of the drive chamber.
