Patent ID: 7287981

Claim:
A method of using a heat sink device with an intraoral illumination device, the method comprising: inserting an intraoral illumination device at least partially in a patient's mouth, the intraoral illumination device configured for illumination of and aspiration of fluid from the patient's mouth; connecting a heat sink device to the intraoral illumination device, the heat sink device including an illumination device that emits light and heat when activated, a heat sink member thermally coupled to the illumination device, a first fluid channel, a second fluid channel, a first lever for controlling aspiration flow through the first fluid channel, and a second lever for controlling aspiration flow through the second fluid channel; activating the illumination device so that light is transmitted to the intraoral illumination device and into the patient's mouth, and heat is emitted from the illumination device, aspirating fluid from the patient's mouth at negative pressure; causing aspirated fluid to flow past the heat sink member at negative pressure so that heat is removed from the heat sink member, causing the illumination device to be cooled; operating the first lever and the second lever for controlling aspiration flow through the first fluid channel and second fluid channel.
