  • Patent number: 8394014
    Abstract: An endoscope comprises a shaft with an outer tube and with an inner tube extending inside the latter, the outer and inner tubes being radially spaced apart from one another such that they form between them an axially extending channel, which provides space for receiving a light guide. An intermediate tube having flexural strength is arranged between the outer tube and the inner tube, which intermediate tube at least partially surrounds the inner tube.

  • Patent number: 6749563
    Abstract: The invention relates to a spreadable medical instrument, comprising a handle part and at least two spatula elements which are connected to said handle part and, via at least one adjusting mechanism, can be adjusted parallel or at an angle to one another between an initial position, in which the spatula elements rest against one another, and at least one working position. In the working position, the individual spatula elements are spaced at intervals so that they form lateral gaps at least in the distal area, and when the spatula elements are in a working position, these lateral gaps between the spatula elements can be covered almost entirely by swiveling flap elements.

  • Patent number: 6508811
    Abstract: A fastening element is provided for securing a rod-shaped element to a shaft of a medical instrument. The fastening element comprises a bracket for engaging at least partially the circumference of the rod-shaped element, where the bracket can be inserted into a side opening of the shaft portion. The fastening element further comprises a tensioning mechanism, which when actuated draws the bracket in the direction out of the opening, thereby clamping the rod-shaped element to the shaft portion. The clamping force of the tensioning mechanism for clamping the rod-shaped element is continuously adjustable when actuating the tensioning mechanism.

  • Publication number: 20020165433
    Abstract: The invention relates to a spreadable medical instrument, comprising a handle part (2) and at least two spatula elements (3a, 3b) which are connected to said handle part (2) and, via at least one adjusting mechanism (4), can be adjusted parallel or at an angle to one another between an initial position, in which the spatula elements (3a, 3b) rest against one another, and at least one working position. In the working position, the individual spatula elements (3a, 3b) are spaced at intervals so that they form lateral gaps (5) at least in the distal area, and when the spatula elements are in a working position, these lateral gaps (5) between the spatula elements (3a, 3b) can be covered almost entirely by swiveling flap elements (6).

  • Patent number: 6261294
    Abstract: A sliding-shaft medical instrument has a sliding shaft that has first and second slide elements, arranged side by side and displaceable axially relative to one another, and at least one jaw part at the distal end that is actuable, by way of a handle at the proximal end, via a relative displacement of said two slide elements, said handle having two handle elements that are movable relative to one another. Said first slide element is mounted, in swing-aside fashion, at a distal end of a tubular shaft that is detachably attached to said handle. In order to actuate said at least one jaw part, said tubular shaft is displaceable relative to said second slide element, and said first slide element can be swung aside when said tubular shaft is detached from said handle and is displaced a further distance.

  • Patent number: 6189422
    Abstract: A screwdriver for introducing and screwing a screw into the human or animal body and/or for unscrewing and removing a screw from the human or animal body has a handle and a shaft whose front end has a blade that can be brought into engagement with a screw head of the screw for screwing the screw. The screwdriver furthermore has a retention device for retaining the screw on the blade. The retention device has an inner tubular shaft which surrounds the shaft and has at the distal end a clamping gripper preloaded into its open position, and an outer tubular shaft surrounding the inner tubular shaft.
