Abstract: A medical instrument, in particular a hysteroscope, has a shaft part (12) having a first shaft and an optical system having a second shaft (40), in which the shaft part (12) and optical system can be displaced with respect to one another along the shafts thereof such that, in a first position, the second shaft (40) of the optical system extends beyond the first shaft of the shaft part (12) on the distal side and that, in a second position, a distal end (23) of the first shaft of the shaft part (12) comes to rest approximately level with a distal end (41) of the second shaft (40) of the optical system.

Abstract: 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. A guide wire may be passed through the Veress needle and through the hole in the peritoneum wall formed by the Veress needle to guide the dilating obturator through the hole.
