Universal probe

The present invention relates to a universal surgical device capable of locating a neurosurgical site, comprising a tubular member, defining a passageway, having a distal end (IOI) and a proximal end; and an elongated navigation probe, which is longer than the tubular member and having a tapering tip, configured to collectively slide into the passageway until the tip protrudes from the distal end of the tubular member, that the tubular member and the engaged probe concurrently move to the neurosurgical site under guidance of a navigation system in communication with the tubular member, wherein the probe moves out from the passageway and the tubular member is retained at the distal end substantially contacting the neurosurgical site.
