摘要

E???ess Mail No. 183 159 702 ENDOSCOPIC SURGICAL INSTRUMENT CLEANING AND FOG ABATEMENT COMPOSITION AND METHOD An endoscopic surgical instrument cleaning and fog abatement composition comprises a surfactant, an evaporator solution, and pyrogen-free water. The composition may be sterilized by gamma radiation exposure and may be thereafter screened and evaluated for free-radical concentration. A method for abatement of fog upon an endoscopic surgical instrument includes applying the fog abatement composition onto a sterile sponge and contacting the instrument with the fog abating composition and thereafter removing excess, non-evaporated composition from the instrument. Subsequent to application of the fog abatement composition onto the surface of the instrument, the instrument may be introduced into a human body during endoscopic surgery without accumulation of fog upon the surface of the instrument.
