Abstract
A trocar has an elongated shaft, and a puncturing head is attached to a distal end of the shaft. The puncturing head can have three blades with sharpened cutting edges. A pathway for light communication is established through three apertures in the puncturing head to a longitudinal bore within the shaft. An endoscope can be positioned in the bore to collect light from the distal end of the shaft. A video monitor is connected to the endoscope for displaying an image of the path of advancement of the trocar.
