"In minimally invasive surgeries, medical access ports (trocars) are inserted through the abdomen to create a working channel through which other tools are passed to perform operations. Surgeons try to minimize morbidity by selecting the smallest possible trocar size. However, in some of the cases, a small diameter trocar must be replaced quickly by a larger diameter trocar to allow entry of larger diameter tools. Xpan has developed a patent-pending trocar that would eliminate the need for trocar replacement when larger tools are needed, thereby reducing costs and time of operations, as well as improving patient safety and reducing morbidity."
