摘要：
A surgical instrument includes a housing, an inner shaft coupled to and extending distally from the housing, an end effector assembly disposed at a distal end of the inner shaft, an outer sheath that is fixed to the housing, extends distally from the housing, and is disposed about the inner shaft, and an insulative sleeve. The insulative sleeve is positioned between the inner shaft and the outer sheath. The insulative sleeve is movable relative to the inner shaft and the outer sheath between a storage position, wherein the insulative sleeve is positioned proximally of the end effector assembly, and a deployed position, wherein the insulative sleeve substantially surrounds the end effector assembly.
