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).

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.

Abstract: The invention relates to a coding system for the identification of tools in medical apparatus as well as to a corresponding method, with which successive code elements (16; 20) are attached on an outer side of a tool, and a stationary read means is arranged on a stationary part of an apparatus in the vicinity of the tool for detecting the successive code elements (16; 20) on movement of the tool (2) relative to the stationary part.

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

Abstract: The invention relates to a cutter for removing tissue, with a cutter head, with a cutter shank which carries the cutter head and to which the cutter head is connected in a rotationally fixed manner, and with a drive driving the cutter shank. For the 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 which is arranged eccentrically to the middle axis of this sleeve, and a second stationary sleeve which is arranged in the inner bore of the first sleeve and which for the passage of the cutter shank comprises an inner bore which is arranged eccentrically to the middle axis of the second sleeve.

Abstract: The instrument serves the application in particular of bone grafts in the space between two vertebrae and consists of a shank, of a handle and of 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 its position which in each case is reached by pivoting.
