AirSeal access sytem used for transanal endoscopic surgery developed by SurgiQuest lands for FDA clearance.
Conventional insufflations and trocar systems use seals and valves to pass instruments into the abdominal cavity and for maintaining internal pressure, but the AirSeal is completely valve-free.
While working on the intra-abdominal organs, endoscopes inserted through the AirSeal are not smudged first and provide a clear view. Moreover, when excising tissue, the valve-free construction of the device allows samples to pass through without being tugged and torn.
The device continuously clears smoke caused by cauterization, keeping the internal volume clear for easy visualization. It can be used for both transanal minimally invasive surgery (TAMIS) and transanal total mesorectal excision (TaTME) procedures.
The hope is that having a consistent seal and clear visualization will speed up these procedures and allow surgeons to consistently remove entire polyps.
