  • Publication number: 20110313255
    Abstract: A veress needle including a housing, a first optical insert for contact viewing, and a second optical insert for distance viewing. The housing including one or more insufflation conduits and an elongate member. The one or more insufflation conduits being adapted to permit the passage and reception of at least one fluid therethrough. The housing defines a passage therethrough. The first and second optical inserts are operably associated with the housing and removably positionable within the passage of the housing while the elongate member remains positioned within tissue. Each optical insert includes an optical assembly having one or more lenses and an ocular. The one or more lenses are adapted to receive an image and transmit the image to the ocular so that the image is perceptible through the ocular.

  • Publication number: 20070010707
    Abstract: An endoscopic coupler by which the rotary and/or linear motion of an external ring is transferred via magnetic interaction of specially configured continuous plastic magnets to a lens resident in a hermetically sealed housing to effect focusing and/or zooming action of the lens without mechanically breaching the integrity of the hermetic seal thereby making the coupler particularly suitable for withstanding the rigors of autoclaving.

  • Publication number: 20050049457
    Abstract: The invention uses optics and precision mechanisms to quantitatively assess the performance of medical endoscopes. By viewing standardized optical targets under well-controlled conditions, the optical quality of endoscopes can be easily determined in much the same fashion as getting one's eyes tested at the optometrist. The actual design, however, is much more complicated than your optometrist's eye chart and different-types of endoscopes from different manufacturers require customization of the target geometry, the viewing distance, and the viewing angle. Also, there are several optical characteristics beyond image sharpness that need to be assessed, requiring other unique test geometries, including contrast, distortion, and vignetting. Clinically significant measurements are performed with simplicity and cost-effectiveness through the use of relatively inexpensive optical components and an embedded processor and graphical display system.

  • Publication number: 20040218083
    Abstract: A lens assembly for producing an image of an object includes a plurality of lenses constructed and arranged to provide a high resolution image, without requiring focusing, of any object within the lens assembly's field of view that is greater than approximately one inch away from the lens assembly, thus providing a constant focus lens assembly. In one embodiment, the plurality of lenses cooperate to provide an effective focal length of approximately 3.53 mm in air, an F number of 11.2 and an angle of view of approximately 34 degrees.
