Abstract

A surgical device for endoscopic surgical procedures capable of preventing injuries to internal organs during insertion. The surgical device can include one or more of the following: at least one sharp bladed edge, a mechanical tissue protection device that includes a series of thin plastic guards sliding along the sides of the blade edges and having an angle between their edges smaller than that of the at least blade edge, one or more fixed conical deflectors to expand the cut tissue passage leaving the guards to contact tissue contact only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.
