What is a veress needle Veress needle is used for the induction of pneumoperitoneum as a technique of preference or when an open technique is considered challenging as in obese patients. This guide covers the basics of veress needle usage and troubleshooting For further clarification, watch our instructional video and subscribe for more informative content A veress needle is held like a pencil by the surgeon who inserts it through the linea alba and peritoneum where a characteristic popping sensation is felt (figure 4). Conmed offers a range of veress needles that establish pneumoperitoneum prior to abdominal surgery and contain safetyview illumination technology.
The veress needle is a specialized medical instrument widely used in laparoscopic (minimally invasive) surgeries to establish a pneumoperitoneum—a controlled inflation of the abdominal cavity with carbon dioxide (co₂) gas. The veress needle, also known as the veress cannula, is a specialized surgical instrument used to create a pneumoperitoneum — the insufflation of the abdominal cavity with carbon dioxide (co₂) gas — before performing a laparoscopic procedure. A spring loaded inner stylet with visual and audible placement indicators provide surgeon assurance during the blind insertion and shields the needle tip once it passes through the abdominal wall and enters into the abdominal cavity.
