Abstract

A trocar comprises a retention cannula comprising an inverted or incised retention pattern disposed thereon. Embodiments of the incised cannula exhibit reduced tissue trauma compared with screw-threaded cannula, improved fixation and/or retention compared with an unthreaded cannula, and good sealing between the cannula and the incision.
