A second‐generation laparoscopic port system: EndoTIPTM

Abstract

BackgroundEver since conventional laparoscopic trocars and cannulas were introduced, concern has been expressed regarding their safety, especially when they are used at the primary port. Despite considerable technological innovation, little has changed in port creation methods and instruments. Numerous publications from reputable centres around the world have warned of the potential dangers associated with their application and design. An interactive new port method is described and an access device is presented with several intuitive safety features which address most of these concerns.MethodThe new port system design evolved through a process of observation, the setting of minimum safety requirements and then cycles of system design, instrument design, prototype construction, evaluation, and redesign.ResultsThe main advantage of the new port system is the ability to introduce 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 ergonomically designed access device allows the surgeon to navigate past vessels, bowel or adhesions during insertion and removal of the cannula, without compromising patient safety or port competence.ConclusionAn interactive visual port system which incorporates intuitive safety features will offer the surgeon an opportunity to better appreciate port dynamics, preserve port competence, and probably decrease laparoscopic access complications.
