Abstract
Abstract A sleeve that is mounted to the tip of a surgical instrument. The sleeve contains a secondary material that changes color as a function of temperature. The instrument may be an ultrasonic tip that emulsifies tissue. The emulsification of tissue generates heat that raises the temperature of the sleeve. The secondary material changes color when the sleeve temperature exceeds a threshold level, thereby providing an indication of an excessive tissue temperature.
