Highlights
●Three electrodes with the structure of oncave-convex, rail coupled concave-convex, and cross rail coupled concave-convex feature were designed for radiofrequency-induced colonic anastomoses.
●The electrode with concave-convex design produced similar temperature between ‘gap’ and ‘compressed’ areas,whereas the rail coupled concave-convex exhibited the highest temperature at 'gap' and 'compressed' areas.
●The cross rail coupled concave-convex electrode, by tightly occluding upper and lower electrodes, could create uniform compression and temperature variation.
