Abstract: A surgical light apparatus is disclosed having a first light source generating visible light and heat energy radiation, an enclosure surrounding the first light source and including a lens substantially transparent to visible light and a reflector for reflecting light from the first light source through the lens, and a filter apparatus coupled to the enclosure and formed at least in part from a material that is substantially transparent to at least a portion of visible light radiation and that substantially blocks transmission of heat energy radiation. The filter apparatus is configured to block transmission of heat energy radiation from the first light source to the reflector and to intercept substantially all radiation from the first light source that otherwise would pass to the reflector and through the lens. The filter apparatus includes a plurality of filter elements configured to define at least one gap between two adjacent filter elements allowing air flow therethrough.

Abstract: A surgical lighthead includes a reflector, a lens coupled to the reflector, and a handle located adjacent the lens. The handle defines an air passage to facilitate installation of a shield over the handle. A lamp assembly includes a support and at least one bulb located on the support between the reflector and the lens. Tubes are mounted in an interior region of the lighthead between the reflector and the lens, and rods are configured to engage the support. Each rod extends through the support and into a corresponding tube. The rods include at least one threaded portion configured to secure the lamp assembly within the interior region. The rods are slidable relative to the tubes upon disengagement of the threaded portions of the rods to permit the lamp assembly to move out of the interior region of the lighthead. The rods include stops to prevent separation of the lamp assembly from the lighthead. A controller turns the bulb on and off and adjusts the intensity level of light emitted from the bulb.

Abstract: A surgical light apparatus comprising a lighthead coupled to an arm adapted for mounting to a surface of a surgical room, and wherein the lighthead has a sterile field at an outlet end thereon, and with a bulb located within the lighthead, a controller coupled to the bulb, and an actuator coupled to the controller to adjust an intensity of light of the bulb itself, and wherein the actuator is located in the sterile field on the lighthead.

Abstract: An arm assembly for supporting a surgical lighthead of a surgical light apparatus includes a first arm and a first clevis appended to the first arm and having a first stop surface and a second stop surface. The arm assembly also includes a second arm formed to include an interior region and a second clevis appended to the second arm and having a third stop surface and a fourth stop surface. The surigcal lighthead is supported by the second arm.

Abstract: An apparatus is provided for preventing the opening of a chamber door of a sterilizer or an autoclave. The apparatus is used on sterilizer and autoclave door systems wherein the door is slidably attached to the chamber. However, the present invention may also be used to control other doors. The apparatus includes a cylinder and piston in fluid communication with the chamber which is actuated when the pressure within the chamber is above a threshold level. A cam, pivotally attached to the side guide bar of the sterilizer, cooperates with the piston to prevent movement of the cam with the piston in the extended position but to allow movement when the piston is retracted. A pin, mounted to the door, cooperates wiht the cam such that the pin must slide along the lobe surface of the cam in order for the door to open. When the piston is in the extended position, the cam cannot move and the pin is received in a recess in the cam surface.
