GUIDE ELEMENT AND DEVICE FOR CREATING A HOLE IN A BONE

摘要

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

1. A device for penetrating extension of a blind bore introduced into hard tissue, in particular into the jaw bone, comprising:
a working tool having a shaft; a hollow body forming a pressure chamber, said hollow body being constructed for sealing insertion into the blind bore and having a distal working opening proximate to the bone during operation, and an inlet opening opposite the working opening; and a guide element closing the inlet opening and having a through hole constructed for guiding therethrough the shaft of the working tool into the hollow body, said guide element having a connection for connection to a tube line, wherein a channel extends in the guide element separate from the through hole from a first opening formed on the connection to a second opening formed axially offset relative to the through opening on an axial end side of the guide element and leading into the hollow body.
