  • Publication number: 20080188716
    Abstract: An endoscope system includes a radiation source which emits a modulated radiation and is applied in a manner such that an object to be examined by an endoscope may be illuminated with the radiation. A sensor is provided for detecting the radiation reflected by the object, at least one picture point. An evaluation device obtains readings of the detected radiation from the sensor, determines phase differences on the basis of these readings, and computes the distance of the object to the sensor device on the basis of these phase differences. A corresponding supplementary module for an endoscope and endoscope optics with these features are also provided.

  • Patent number: 7319478
    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.

  • Patent number: 7186261
    Abstract: A medical forceps is provided with a tubular outer shank, on whose distal end there is formed a forceps jaw with two jaw parts. The two jaw parts are each rotatably mounted on the outer shank at two sides opposite one another. A tubular inner shank for actuating the jaw parts is displaceably arranged in the inside of the outer shank in its longitudinal direction. The inner shank is coupled to the two jaw parts for their actuation via two lever systems. Each of the lever systems is linked to the two jaw parts, one lever system on each of the two opposite sides.

  • Patent number: 6970620
    Abstract: In the region of a distal end at its circumference the waveguide is formed transparent to the radiation which impinges onto the surface of the waveguide at suitable angles, and in the region of the distal end in the inside of the waveguide there are arranged scatter elements which scatter radiation transmitted by the waveguide in the direction of the distal end in a direction with a proximally directed component which exits the circumference of the waveguide. Alternatively, radiation entering into the waveguide at the circumference of the waveguide in a direction with a distally directed component is transmitted by the waveguide in the direction of the proximal end, as well as to its use and to a method for its manufacture.

  • Patent number: 6947091
    Abstract: A focussing and focal length adjusting device for an optical lens system in the camera head of an endoscope. This device includes a focussing device which has several piezoelectric bending actuators attached along and symmetrically to the optical axis of the focussing lens. The piezoelectric bending actuators are via in each case one joint member connected to a sleeve encompassing the focussing lens in a manner such that with voltage impingement bending movements carried out by the bending actuators are converted into a linear focussing movement for the focussing lens. Furthermore a zoom drive adjusting the focal length of a zoom lens system includes a stepper motor whose stepped rotation via a grooved roller and a pin linearly moved by the helical groove of this roller is converted into a linear movement of a zoom lens sleeve for the focal length adjustment.

  • Patent number: 6918916
    Abstract: The target apparatus for positioning a drilling tool with respect to a drilling channel to be created in a bone consists of a target hook and a guide arm which is releasably connected to this and on which there is arranged a receiver for the drilling tool, and a guide path in the form of a laterally through-going open groove for the guide arm. The guide arm may be displaced and fixed in the guide path. A simple assembly and disassembly of the apparatus is achieved in that the guide arm on the side of the apparatus is applied into the guide path through the groove opening and reversely, by lifting away out of the groove, may be separated from the target hook.
