The use of smaller ports in surgery is the next step in the evolution of minimally invasive procedures. We present findings, using a novel flexible needle made from a super elastic titanium alloy, which demonstrate that it is possible for a 26- and 30-mm needle to pass through a 3.5- and 5-mm trocar. This new approach results in less trauma and improved cosmetic effect in comparison to the classical 10-mm port. Traditional steps such as handling of the needle holders, loading the needle and placing it at the correct angle and direction, inserting the needle into the tissue and finally safely tying a knot remain the same as with the standard procedure. We propose that this improved type of needle creates a refinement opportunity to replace the classic ones during both laparoscopic and robotic surgeries.
