  • Publication number: 20110106143
    Abstract: A medical instrument includes a handle on the proximal end and a shank rotatably arranged on the handle. A tool is arranged on the distal end of the shank. This tool is rotatable relative to the shank. An actuation element is arranged on the handle. The actuation element may be moved into at least two switch positions, wherein in a first switch position the actuation element is coupled in movement to the shank and in a second switch position the actuation element is coupled in movement to the tool.

  • Publication number: 20100287755
    Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.

  • Publication number: 20090023988
    Abstract: An endoscopic instrument includes a rigid hollow shank (2) and a tool (8) at the distal instrument end. The tool (8) is driven in rotation via a drive shaft (14), which is guided within the hollow shank (2). At the distal end of the hollow shank (2), the tool (8) projects out of the hollow shank (2), where it may be angled with respect to the distal end of the hollow shank (2).

  • Patent number: 7445624
    Abstract: The sample taker comprises a hollow shank with a scoop fixedly connected at its distal end, a handling means provided at the proximal end of the 20 hollow shank and an actuation mechanism. An actuation rod is axially movable in the hollow shank and connectable to the actuation mechanism. A covering is allocated in the trough of the scoop. The covering is fastened to a distal end of the actuation rod and displaceable forwards and backwards.

  • Publication number: 20080249364
    Abstract: An endoscopic instrument having a flexibly designed tube shank is provided in which the tube shank is formed of several tube sections connected to one another in an articulated manner. Two adjacent tube sections are respectively connected to one another, in additional to the articulated connection (6), via at least one connection web (18), which is resilient in the axial direction of the tube shank.

  • 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.

  • Patent number: 6565587
    Abstract: A cutter for removing tissue has a cutter head, a cutter shank which carries the cutter head and to which the cutter head is connected in a rotationally fixed manner, and a drive driving the cutter shank. For adjustability of the effectiveness of the cutter with the removal of cartilaginous or bony tissue parts, there is provided a first rotatable sleeve which comprises an inner bore arranged eccentrically to the middle axis of this sleeve, and a second stationary sleeve arranged in the inner bore of the first sleeve and which for passage of the cutter shank comprises an inner bore arranged eccentrically to the middle axis of the second sleeve.
