An improved sleeve for a microsurgical instrument, such as a phacoemulsification handpiece, is disclosed. The sleeve has a hollow body for receiving a moving tip, and an electrically conductive film disposed on an outer surface of the body. The film may be electrically coupled to electrical circuitry that measures the temperature of the film. The temperature may be provided to a surgical console. The console may visually display the temperature, may provide an audible warning when the temperature exceeds a certain threshold, or may adjust console parameters, such as ultrasound power, in response to the temperature value. |
