In general a trocar system requires a sharp obturator to create a path for insert the trocar inside the abdominal wall. So these obturators need some kind of sharp conical pointed tip to minimize the penetration/insertion force during insertion. A small damage to tip can cause a significant increase in the insertion force and can also damage surrounding tissues. The tip damage can be prevented by providing a tip protector with the assembly. This tip protector will also prevent any damage while handling during transportation and before surgery. This invention provides a cost effective solution for this problem.
