  • Patent number: 6364830
    Abstract: A variable-view arthroscope or like instrument (endoscope, etc.) includes an elongated housing tube extending from an outer control end to an inner image input end that is closed by an input lens or window. A lighting apparatus illuminates a surgical working area beyond the image end of the housing tube. A first mirror intercepts light reflected from the surgical working area to produce a working image that is reflected to a second mirror that in turn reflects the working image to impinge upon the input end of a relay lens assembly. The working image is transmitted to a receptor, which is located near the outer (control) end of the housing tube. The relay lens applies the image to an image device, such as a conventional CCD unit, that transmits the image to a location exterior to the scope. A control varies the position of one or both of the mirrors between first and second limits.

  • Patent number: 6306082
    Abstract: The illuminating light transmitted by the light guide inserted through the elongate inserted section is projected out of the distal end surface of the inserted section. The illuminated objects pass through the respective non-superimposed pupils of the two objective lens systems arranged in parallel within the distal end section of the inserted section and their images, which are not equal to each other are formed on the focal surface. The respective images are transmitted to the rear side by one common relay lens system having a single optical axis. The transmitted final images are formed respectively on the image taking surfaces of the image taking devices. The respective images photoelectrically converted by the respective image taking devices are processed to be signals, are displayed in the monitor and are stereo-inspected through shutter spectacles.

  • Patent number: 6277064
    Abstract: A surgical endoscopic instrument for operating on anatomical tissue includes a rigid barrel, a shaft extending through the barrel and an offset endoscope mounted on the shaft. The endoscope is offset from the longitudinal axis of the shaft by a transverse connecting member, thereby permitting the endoscope viewing end to move through an arcuate path outside the diametrical dimension of the barrel. During insertion of the instrument through a portal or the like, the offset endoscope can be positioned within a diametrical dimension of the surgical instrument, either by rotating the shaft or by drawing the shaft and the endoscope viewing end into the barrel in an axial manner. The offset endoscope may be aimed to provide an oblique field of view of a surgical procedure and may include an articulable ball joint having a solid state imaging sensor and light source; the ball joint imaging sensor aim is preferably articulable or controllable from the instrument proximal end using control members (e.g.

  • Patent number: 6248060
    Abstract: A rigid endoscope includes a jacket tube with an optical system and, parallel to the optical axis of the optical system, a first glass fiber bundle which emits a beam to illuminate an object to be examined. A second optical illumination system is directed at the object being examined. The second light exit of the second optical illumination system is recessed from the first light exit of the optical system by a distance greater than a diameter of the jacket tube. The light exit axis at the second light exit of the second optical illumination system is offset laterally relative to the image axis at the distal end of the optical system by an amount such that because of the resultant parallax and the shadow formation and unequal light distribution thus attained, the vividness of the image impression for three dimensional objects is increased.
