  • Patent number: 8376936
    Abstract: A videoscope preheater for preheating an endoscope includes: a support tube; an electrical heating layer uniformly coated on an outer surface of the support tube, one side of the electrical heating layer being connected with a power cable for connecting with an external power supply; and a capsule layer coated on an outer surface of the electrical heating layer for fixing and protecting the electrical heating layer and the power cable. The capsule layer is a thermally contractible capsule film, which is fitted around the electrical heating layer and then heated to contract for insulating the electrical heating layer and the support tube from ambient environment. In use, the endoscope is fitted into the support tube and the electrical heating layer is powered on to generate heat and uniformly heat the endoscope. The heating efficiency of the videoscope preheater is controllable by means of adjusting the current and voltage input.

  • Patent number: 8353819
    Abstract: A protective sleeve apparatus for protecting an endoscopic or laparoscopic instrument includes an elongated tubular member having an open proximal end and an open distal end. The elongated tubular member is sized and configured to receive a laparoscopic or endoscopic instrument therethrough. The tubular member has a folded section adjacent the distal end in releasable engagement with an intermediate section of the tubular member to define a substantially enclosed sleeve to receive the instrument and substantially prevent entry of contaminants within an interior of the tubular member. The folded section is releasable from the intermediate section upon exertion of a proximal force to the tubular member to facilitate removal of the tubular member along the instrument.

  • Patent number: 8096944
    Abstract: An air shield for a videoscope imager to prevent obscuring of the optical input by body liquids and tissue particles. The imager is extended through a tube carrying a pressurized gas so that when the gas escapes from the end of the tube, it generates an air stream envelope around the optical input of the imager and prevents liquids and particles directed toward the optical input from contacting the optical input. The pressurized gas flows continuously during the medical or dental procedure to maintain a constant resistance to liquids and matter directed to the optical input of the imager.
