A trocar assembly (2) includes a hand grip (4) and a trocar obturator (6). The trocar obturator includes a front end on which is mounted a piercing tip (8), 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 (16) is mounted on the rear end of the obturator, and is rotatably but securely received by a socket (18) formed in the hand grip. |
