Stainless Steel Trocar

Trocars are used in medicine to access and drain collections of fluid such as in a patient with hydrothorax or ascites. In modern times, surgical trocars are used to perform laparoscopic (keyhole) surgery. They are deployed as a means of introduction for cameras and laparoscopic hand instruments, such as scissors, graspers, etc., to perform surgery hitherto carried out by making a large abdominal incision ("open" surgery), something that has revolutionized patient care.
