Surgical Trocar

A Trocar is a surgical instrument used to establish access ports for laparoscopic and minimally invasive procedures. Consisting of a sharp or bladeless obturator housed within a cannula, it provides entry into the abdominal or thoracic cavity while maintaining pneumoperitoneum through integrated sealing valves. Available in various diameters (3-15 mm) and configurations (bladed, bladeless, optical, reusable, disposable), trocars enable the safe passage of laparoscopes, graspers, scissors, and staplers, forming the foundation of modern minimally invasive surgery.
