Brain measurement probe insertion arrangement, is simpler, cheaper and can be applied more safely

摘要

The arrangement has a skull bolt (8) that can be penetrated via a longitudinal bore by the measurement probe (29) and a guide tube accommodating it in a bore (14). A crimp bolt is used to radially crimp the seal the measurement probe and guide tube on the skull bolt. A protective tube encloses the measurement probe and connects the skull bolt to a probe coupling (25). The guide tube (11) has further separate bores (16,17) for accommodating further measurement probes and carries the probe couplings (26) on the near end of the bores to form the protective tube.
