An instrument heater for heating a surgical instrument. The instrument heater includes a sheath having an inner and outer wall. The inner wall forms a bore through which the optical scope is inserted. A chemical solution fills the space between the inner and outer wall of the sheath. At one end of the sheath is an activator disk having a chemical substance attached to its surface. When the activator disk is flexed, it ejects the chemical substance and interacts with the chemical solution to initiate an exothermic reaction. The exothermic reaction results in the generation of heat within the sheath, which is transmitted to the surgical instrument. Once the surgical instrument is sufficiently heated to a temperature close to the temperature of a body, the optical scope is inserted into the body. A natural tendency for the instrument to fog up is prevented by the equalizing the temperature of the instrument with the body.

[ What is claimed is:] [1.] An instrument heater for heating an instrument comprising:a sheath capable of surrounding the instrument, the sheath having:an inner wall forming a bore adapted for the instrument;an outer wall forming a void between the inner wall and the outer wall;a chemical solution filling the void between the outer wall and the inner wall; anda first end forming an opening for receiving the instrument; andan activator disk attached between the inner wall and the outer wall of the sheath, the activator disk having a substance, whereby the activator disk expels the substance when flexed causing an interaction of the substance with the chemical solution, the interaction of the substance and the chemical solution generating heat within the sheath.
