Abstract
Abstract A sterile sheath for enclosing certain surgical illuminating lamp structures having elongated light transmitting shafts with a light transmitting lens means disposed at the tip end of the light transmitting shaft. The sheath means of the present invention comprises an elongated tubular sheath having a closed tip at one end thereof and an opening at the other end thereof, the tubular sheath having sufficient length to cover that portion of the light transmitting shaft having a sterile requirement. The sheath is provided with a light transmitting tip at the closed end and has a pair of generally axially extending slots formed adjacent the open end to form a pair of grasping ears. One of the axially extending slots has a length in substantial excess of the other in order to provide the grasping ears with substantial asymmetry.
