Abstract: A working insert for an endoscopic hollow shank instrument includes a shank, on whose outer side is arranged a monopolar working electrode axially displaceable relative to the shank. The working electrode is connected to the shank at a distal end section of the shank via a guide component which forms an electrical insulation between the working electrode and the shank.

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.

Abstract: A surgical guiding device is provided for reconstruction of the anterior cruciate ligament, including a guide arm and a guide hook extending away from the arm. The guide arm is constructed in the form of an arc, supports a mounting that is slidable on the guide arm and has a fixing device for an alignment wire that is separate from the mounting.

Abstract: The rigid endoscope has a shank-like middle part, on which a handle connects on a proximal side and which on a distal side includes a distal part with an optics window. The handle is arranged offset or obliquely to a longitudinal axis of the middle part, as well as of the distal part, in order to provide free space in the region of the handle of the working instrument as well as on the distal side of the tool.

Abstract: A trocar sleeve includes a distal tubular section, a section which connects to the distal tubular section at a proximal side of the distal tubular section and which is widened proximally, and at least one spiral with a circular outer contour, arranged helically on a periphery of the distal tubular section. The distal tubular section includes a rounded polygonal cross section so that maximal degrees of freedom of the applied instruments result.

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.

Abstract: An endoscope and shaft system include an access shaft and an endoscope which can be inserted into the access shaft, the proximal end of the access shaft has a grip part, and the endoscope is held in a connecting piece. The connecting piece can be detachably connected to the grip part, and the connecting piece can be rotated about the longitudinal axis of the endoscope relative to the grip part when the connecting piece is connected to the grip part.

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.

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.

Abstract: The instrument serves for the application in particular of bone grafts in the space between two vertebrae and includes a shank, a handle, and a holder for the implant, which forms the distal instrument part. The holder is pivotably mounted relative to the shank and can be fixed in any respective position which is reached by pivoting.

Abstract: The device for conditioning an organic ligament to be implanted, in particular a ligament as a cruciate ligament replacement, is equipped with first and second receiving elements for receiving and tensioning the ligament at two spaced locations. The first receiving elements is connected to means for the periodic translatory adjustment of the first receiving element with respect to the ligament.

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.
