ABSTRACT:
An extractor consisting essentially of a guide barrel, a clamping element and a pull wire. The bordering end faces of the guide barrel and clamping element feature each a bevel which is complementary in design to the other. The pull wire is joined to the clamping element. The clamping element is moved on the bevel in the direction of the proximal end of the extractor by application of traction force on the pull wire, thereby enlarging the greatest outside diameter of the guide barrel in the area of the bevel. The relatively long design of the bevels assures with low traction forces an anchoring of the extractor in an electrode spiral by frictional engagement.
