摘要： An evacuation system is provided for removing smoke generated during a surgical procedure performed in a surgical room. The evacuation system includes a pre-filter assembly and a replaceable filter cartridge module disposed in the surgical room to permit replacement of used filter cartridge modules with new filter cartridge modules by personnel within the surgical room. A vacuum generator is disposed outside of the surgical room and includes a vacuum pump for establishing an air flow through the replaceable filter cartridge module. The pre-filter assembly includes an elongate flexible suction hose that is adapted for manipulation into position adjacent the medical procedure. A mechanical connection mechanism enables pre-filter assemblies to be easily replaced between each surgical procedure. An accumulated filter usage circuit calculates a quantity of filter capacity available and generates a filter loading signal based on the available capacity. The filter usage is calculated by adjusting usage counter in proportion to the speed of a vacuum motor and pump mechanism.

摘要： A surgical task light is provided including a light source adapted to generate light. An elongate optical fiber carries the light generated by the light source to a remote target site. The optical fiber includes a proximal end for receiving the light generated by the light source and a distal end for emitting the light. A support member supports the optical fiber relative to the ceiling of an associated operating room and holds the optical fiber in a plurality of selected positions. A lens device is carried on the distal end of the optical fiber for focusing the light emitted from the distal end of the optical fiber into a desired selected pattern. A sterile sheath member in combination with the surgical task light provides a sterile barrier between the surgical area and the mechanical and optical portions of the task light. A re-lamping module includes a replaceable light bulb module carrying a light bulb to help facilitate replacement of the light bulb by maintenance personnel. A cooling system cools the light bulb and defines an air duct for directing an air flow through heat dissipating members. The air duct is separated from the optical light path between the light bulb and the elongate optical fiber to prevent the air flow from entering the light path to prevent dust and other contaminants from reducing the optical efficiency of the system.
