Universal, Abdominal Nelson Trocars

A trocar is a sharp, pointed instrument used in surgery for creating an opening into a body cavity, such as the abdomen or chest, for accessing and draining fluid or for inserting other instruments. It typically consists of a pointed metal shaft with a sharp tip, a cannula, which is a tube-like structure, and a mechanism for securing the trocar in place. Trocars are commonly used in minimally invasive procedures such as laparoscopy and thoracoscopy.

It also known as Nelson (Patterson) Trocar is an instrument designed for use in cardiothoracic surgical procedures that require drainage of fluids. This instrument is uniquely suited for the withdrawal of fluids via intercostal access. It features a bulb-shaped handle that extends a shaft that ends with a slightly sharpened tip which facilitates controlled and safe intercostal penetration. This instrument is available in four different French sizes which makes this a highly versatile tool.
