trocar cannula

A trocar cannula is a medical device used during minimally invasive surgeries, such as laparoscopy. It consists of a sharp, pointed instrument called a trocar that creates an entrance through the skin and abdominal wall. Once the path is established, the trocar is removed, leaving the cannula—a hollow tube—embedded in the tissue. This cannula serves as a protective passageway, allowing surgeons to insert small instruments, cameras, or other tools into the body safely and efficiently without repeatedly puncturing the skin. It improves access, reduces trauma, and helps in precise surgical procedures.
