Abstract: The invention relates to a device for penetratingly extending a blind hole into a hard tissue, particularly a jawbone. The device is characterized in that it comprises a tubular body (1) having a distal working opening (2) and an inlet (3) opposite the working opening (2), said inlet being closed by a sealing element (4) that is penetrated by a shaft (5) of a working tool, for example a milling tool (5, 6), and allows at least a feed motion, a drive motion and a steering motion of the working tool (5, 6), the tubular body (1) being provided with a connection (8) for applying an internal pressure.

Abstract: A surgical instrument for use in a sinus lift includes a substantially cylindrical sleeve which is sealingly insertable into a bore of a jawbone. The sleeve has a lumen and is formed with an inlet channel and an outlet port which is in fluid communication with the lumen. A vibration unit is operatively connected to the instrument for transmitting vibrations into the lumen.

Abstract: A guide element is constructed for arrangement on a device for the penetrating extension of a blind hole created in hard tissue, in particular in the jawbone, wherein the device includes a hollow body that forms a pressure chamber and that has a distal working opening and an inlet opening opposite the working opening. The guide element can be inserted into the inlet opening with a tight fit and the inlet opening can be closed by the guide element, the guide element has a through-hole, through which a shaft of a working tool, for example, of a milling tool, can be guided and inserted into the hollow body, and the guide element has a connection for a working medium for applying an internal pressure in the pressure chamber or in the hollow body.
