A trocar assembly includes a hand grip and a trocar obturator. The trocar obturator includes a front end on which is mounted a piercing tip, and an opposite rear end. The trocar obturator is mounted on the hand grip at its rear end, and is adapted to rotate independently of the hand grip. A retaining head is mounted on the rear end of the obturator, and is rotatably but securely received by a socket formed in the hand grip.
