  • Surgical instrument with adjustable tool for gripping, holding or cutting body tissue or the like
    Patent number: 6814745
    Abstract: A surgical instrument has a tool located at the distal instrument end, a stationary first grip part at the proximal instrument end, a second grip part adjustable in an axially guided manner in the form of a reel, and an actuation element for the tool. The actuation element in connection with the second grip part is axially adjustable on adjustment of the second grip part. For improving the handling of the instrument, it is envisaged that, by way of a lever system linked onto the second grip part and a stationary part of the instrument, the adjustment path of the second grip part is geared down and the force exerted onto the second grip part is transmittable, geared up, to the actuation element.

  • Device for the picture providing and spectroscopic diagnosis of tissue
    Publication number: 20040019281
    Abstract: The invention relates to a device for the picture-providing and spectroscopic diagnosis of tissue with the alternative or combined use of three diagnosis methods, specifically a mode A for the picture-providing white light diagnosis, a mode B for the picture-providing fluorescence diagnosis and a mode C for the fluorescence-spectroscopic diagnosis. The device comprises a first light means whose light as a beam bundle via a beam path is coupled into an optical fiber leading to an endoscope and a second illumination means whose light as a beam bundle via a second beam path may be coupled into the same fiber-optic. In the first beam path there is arranged an element widening the bundle opening, for the light beam bundle entering into the fiber-optic and in the second beam path there is arranged an element limiting the bundle opening, for the light beam bundle entering into the fiber-optic.

  • Solid-state video camera and method for brightness control
    Publication number: 20030189663
    Abstract: A solid-state video camera is equipped with pixel addition logic such that, if the measured object brightness falls below a certain threshold value, a brightening of the image is effected without increasing the noise component accepting a loss in real-time representation. The pixel addition by way of the pixel addition logic is coupled to the gain control of the camera in a manner such that, in each case, the gain control compensates for jumps in brightness which arise by way of the pixel addition and creates for the user a flowing transition without noticeable jumps in brightness.
