A device for facilitating insertion of a surgical instrument into a human body through an opening in a body wall including a cone-shaped member having a rounded front end, an internal cavity extending inward from a rear edge and a through opening arranged at the front end. At least part of the surgical instrument is received in the cavity such that the surgical instrument is insertable into the body through the opening in the body wall by urging the member through the opening with its front end forward and thereby causing tissue surrounding the opening to spread outward as the member passes through the body wall. The instrument is separated from the member after insertion of the member and the instrument into the body. The member can be removed from the body through same opening through which it was inserted into the body.

At least part of the surgical instrument is received in the cavity such that the surgical instrument is insertable into the body through the opening in the body wall by urging the member through the opening with its front end forward and thereby causing tissue surrounding the opening to spread outward as the member passes through the body wall. The instrument is separated from the member after insertion of the member and the instrument into the body. The member can be removed from the body through same opening through which it was inserted into the body. The device is fabricated as a single piece without detachable or moving parts thereby facilitating cleaning and sterilization.
