A trocar system (10, 12) includes a cannula (100, 500) having a cannula head (110, 510) and a cannula tube (300, 600), and an obturator (400, 700) 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 (110, 510) may include a resilient non-slip material (140). The cannula head (110, 510) may also include a monolithic housing (130) having a port (160) with a Luer Lock fitting and an integrally formed passageway (150) for receiving a stopcock valve (170).
