ABSTRACT:
The present invention relates to a trocar adapted to provide a surgeon with an indication when the trocar has penetrated body tissue. The trocar includes an obturator assembly and a cannula assembly. The obturator assembly has an obturator housing and an obturator shaft. The shaft has a proximal end portion connected to the housing and a distal end portion adapted to conduct electricity and penetrate body tissue. An electric connection assembly is associated within the obturator housing and provides a conductive path between the conductive portion of the obturator shaft and an outer surface portion of the obturator housing. The connection assembly is also adapted to receive an external electrical connector.
