What is a Trocar | SurgSci

June 09, 2023

A trocar is a medical instrument consisting of an awl with a pointed or tapered tip, a cannula (a hollow tube), and a seal. During laparoscopic surgery, trocars are inserted through the abdomen to serve as a portal for other instruments and to allow the release of gas or fluid from organs.

The term “trocar” is derived from the French word “trocart,” which means “three-fourths” and refers to the three sides or faces of the instrument. Trocars have been used for centuries to relieve pressure caused by fluid or gas buildup.

Trocars can be either reusable or disposable. Reusable trocars have conical or pyramidal tips and can save hospitals money over time. However, their tips can become dull with use. Disposable trocars are used once and then discarded. Some disposable trocars are designed to improve patient safety and offer ergonomic benefits such as increased comfort and control during insertion.
