Abstract
A trocar system includes a cannula having a cannula head and a cannula tube, and an obturator having a cap and either a rounded tip or a cutting blade. The head and cap form an ergonomically shaped bulbous handle. At least a portion of an outer surface of the cannula head may include a resilient non-slip material. The cannula head may also include a monolithic housing having a port with a Luer Lock fitting and an integrally formed passageway for receiving a stopcock valve.
