Abstract:
1. A method of perfouning a surgical micro-resecting procedure at a target site of a patient, the method comprising: providing a micro-resecting instrument including: electrically connecting the wiring to an evoked potential monitoring device such that an energy source of the evoked potential monitoring device is in electrical communication with the probe surface; delivering the distal section of the outer tubular member toward the target site such that the cutting window is adjacent the target site; applying a stimulation energy to the probe surface via the energy source and the wiring; operating the evoked potential monitoring device to evaluate a proximity of the probe surface relative to a bodily structure of interest based upon reference to the applied stimulation energy; rotating the inner member relative to the outer tubular member to perform a micro-resecting operation in which bodily material at the target site is resected by the cutting tip within the cutting window; and attaching a motorized handpiece to the hub assembly such that operation of the handpiece causes the inner member to rotate relative to the outer tubular member, and further wherein the hub assembly electrically isolates the micro-resecting instrument from the handpiece.
