[0002] A trocar is a surgical instrument that pierces the wall of a body cavity to provide a channel for other surgical instruments to enter the body cavity. It is a minimally invasive surgical instrument. Traditional trocars generally include a cannula assembly and a trocar needle core. By applying pressure to the trocar, the tip of the trocar is pushed through the skin until the trocar enters the body cavity.
