1. A method of cutting a first tissue proximate to a second tissue with a surgical instrument including a shaft, a cutting member, and a tissue monitor system, the shaft extending along a longitudinal axis and including a cylindrical body having a distal edge and a shaft lumen extending along the longitudinal axis and a shaft opening in fluid communication with an environment and the shaft lumen, the cutting member being disposed within the shaft lumen and configured to cyclically move from a first position to a second position relative to the shaft, the cutting member being configured to cut a tissue portion of the first tissue for removal therefrom, the tissue monitor system being associated with at least one of the shaft or the cutting member, the tissue monitor system being configured to detect the second tissue distinct from the first tissue, the method comprising:
(a) cutting the tissue portion from the first tissue with the cutting member;
(b) detecting at the distal edge the second tissue with the tissue monitor system while cutting the tissue portion from the first tissue; and
(c) ceasing movement of the cutting member after detecting the second tissue to thereby inhibit cutting the second tissue.
