  • Patent number: 7429257
    Abstract: An endoscopic instrument includes a first instrument part adapted for introduction into a cavity of a human body and having an introduction channel therein for passage of gas therethrough, and a second instrument part having a connection channel therein adapted to be connected to the first instrument part introduction channel. The second instrument part is adapted for connection to a gas source to provide gas, at a flow rate suitable for insufflation of a human body cavity, from the gas source through the connection channel to the introduction channel for introduction into the human body. A heating device heats the gas in the introduction channel to substantially the temperature of the human body.

  • Patent number: 6676598
    Abstract: A laryngoscope includes a handle, a spatula arranged substantially transverse to the handle, and a coupling detachably fixing the spatula to the handle. An illumination light waveguide guides an illumination light signal and an image waveguide guides an image signal, both waveguides being attached to the spatula. The illumination light waveguide includes a proximal end having an illumination light entry opening, and the image waveguide includes a proximal end having an image exit opening, wherein the illumination light entry opening and the image exit opening are arranged in the area of the coupling. The handle includes, in the area of the coupling, an illumination light exit opening and an image entry opening which allow for the illumination light signal to couple into the illumination light waveguide from the handle, and for the image signal to couple out of the image waveguide. A centering element automatically aligns the image entry opening and the image exit opening precisely to each other.
