Abstract:
1. A system for use in resecting tissue of an anatomical structure, the system comprising: a surgical instrument; a plurality of cutting devices selectively attachable to said surgical instrument and configured to resect the tissue, each said cutting device defining a first longitudinal dimension, said first longitudinal dimension of each of said plurality of cutting devices being different from one another; and a plurality of calibration devices selectively attachable to said surgical instrument, each said calibration device defining a second longitudinal dimension, said second longitudinal dimension of each of said plurality of calibration devices being different from one another, wherein each of said plurality of cutting devices is configured to cooperate with each of said plurality of calibration devices to set a depth of resection for said surgical instrument, said depth of resection for any combination of one of said plurality of cutting devices and one of said plurality of calibration devices being substantially equal to the difference between said first longitudinal dimension of said one of said plurality of cutting devices and said second longitudinal dimension of said one of said plurality of calibration devices, whereby said depth of resection is adjustable by altering the combination of said one of said plurality of cutting devices and said one of said plurality of calibration devices, wherein each of said plurality of calibration devices includes a reference surface and said surgical instrument includes a receptacle for selectively housing said plurality of cutting devices, said receptacle defining a proximal end, said second longitudinal dimension of each of said plurality of calibration devices defined between said proximal end of said receptacle and said reference surface of each of said plurality of calibration devices when each of said plurality of calibration devices is attached to said surgical instrument.
