Abstract
A sleeve shaped body having a liquid absorbent segment and a wettable segment is positioned on a speculum member during a medical procedure in which a laser instrument is utilized. The liquid absorbent segment inhibits reflection and dissipates the energy of any errant, impinging laser beams. Placement in a body cavity of the speculum with the sleeve shaped body positioned thereon is facilitated by use of the wettable segment which provides for a relatively low sliding friction in contact with human body tissue. A method using this technique is described.
