摘要：
An endoscopic tissue resecting system that includes a reciprocating rotary surgical instrument for cutting tissue that includes a planetary gear assembly to vary rotational speed. A method of cutting and detaching tissue includes positioning an outer member such that tissue is located within a window in the outer member, engaging the tissue with an inner member, and simultaneously rotating at an increased speed relative to a rotary driver and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut and detach the tissue.
