摘要：
A trocar obturator includes a shaft having a proximal end and a distal end. The trocar obturator also includes a tip positioned at the distal end of the shaft, the tip including a distally extending blade structure adapted to reduce penetration forces required during insertion of the trocar obturator. The blade structure includes a first cutting edge and a second cutting edge.
