Abstract

This invention is a medical instrument including a Veress needle (18), a dilating obturator (28), and a cannula (26). The needle has a tubular safety obturator (22) with an opening in its front section at a needle tip (20). A guide (10) with a guide slot can be positioned in a patient's vagina against the posterior fornix to guide the needle through the vaginal and peritoneal walls. A guide wire (24) may be passed through the needle, and through the hole (30) in the peritoneum wall formed by the needle to guide the obturator through the hole.
