New egzoluminal circular surgical stapler.
The study presents the design, prototype version and preliminary results of in vivo testing of the egzoluminal circular surgical stapler for "end-to-end" anastomosis of bowels after the resection, where staples are put outside the intestinal lumen, and walls of the intestinal tube directly contact the intestinal mucous membrane. The adopted idea of an "end-to-end" intestinal anastomosis as well as a strong need for a device that would be re-usable have determined its specific design. The device is characterised by a kinematic mode of operation, different from the operating mode of commonly used staplers, and hence by a specific combination of the individual components. The in vivo tests, successfully conducted on animals, have proved that this method of anastomosis as well as the device used for its practical performance are fully applicable in clinical practice, as best shown by patent application No. P 386369.
