A medical instrument comprising a Veress needle, a dilating obturator, and a cannula. The Veress needle has a tubular safety obturator with an opening in its front section at a needle tip of the Veress needle. A guide with a guide slot can be positioned in a patient's vagina against the posterior fornix of the vagina to guide the Veress needle through the vaginal and peritoneal walls.
