A second-generation laparoscopic port system: EndoTIP(TM)

Background Ever since conventional laparoscopic trocars and cannulas were i ntroduced, concern has been expressed regarding their safety, especially wh en they are used at the primary port. Despite considerable technological in novation, little has changed in port creation methods and instruments. Nume rous publications from reputable centres around the world have warned of th e potential dangers associated with their application and design. An intera ctive new port method is described and an access device is presented with s everal intuitive safety features which address most of these concerns. Method The new port system design evolved through a process of observation, the setting of minimum safety requirements and then cycles of system desig n, instrument design, prototype construction, evaluation, and redesign. Results The main advantage of the new port system is the ability to introdu ce and remove laparoscopic ports in an incremental visual way, without the use of axial penetration force and without the use of a trocar. Our novel e rgonomically designed access device allows the surgeon to navigate past ves sels, bowel or adhesions during insertion and removal of the cannula, witho ut compromising patient safety or port competence. Conclusion An interactive visual port system which incorporates intuitive s afety features will offer the surgeon an opportunity to better appreciate p ort dynamics, preserve port competence, and probably decrease laparoscopic access complications.
