ABSTRACT:
A laparoscopic defogging apparatus for regulating and maintaining the temperature of a lens and end portion of the laparoscope is disclosed. A receptacle is provided which contains a first sterile fluid at a sufficient depth to allow the lens and end portion of the laparoscope to be placed in thermal contact with the first sterile fluid. A container is provided into which the receptacle is placed, which container is adapted to receive and contain a second sterile fluid at a sufficient depth to provide thermal contact with at least a part of the receptacle side wall portion. A heating device is provided to heat the sterile fluids whereby the laparoscope is maintained at a constant desired temperature, thereby preventing lens fogging.
