ABSTRACT:
A surgical instrument and support unit for enabling a user using one hand to probe an incision and illuminate, irrigate, and aspirate the incision. The surgical instrument has a probe with illumination, irrigation, and aspiration ports on the end. The probe is coupled to a handle having controls for the irrigation and aspiration functions. Light from a high intensity lamp in the handle is transmitted through an optical fiber to the illumination port. A heat sink enclosing the lamp draws heat away from the lamp and transfers the heat to the aspirated fluid passing through the heat sink. The support unit is controlled by a microcomputer and provides an electrical supply for the lamp and a pressurized fluid supply for irrigation. The sources of the irrigation fluid is a standard hospital flexible bag. A bladder inflated by an air pump pressurizes the flexible bag. The pump is also utilized to deflate the bladder to allow rapid changing of the flexible bag during a surgical procedure.
