Which description best matches a Veress needle?

• A. A spring-loaded needle with a sharp tip and a conduit for the insufflation of gas
• B. Trocar with obturator
• C. A blunt instrument for tissue dissection
• D. A suction device

Answer: (A)

The Veress needle is the instrument used to create pneumoperitoneum by delivering CO2 into the peritoneal cavity, and it includes a spring-loaded safety feature with a hollow lumen for gas insufflation. Its sharp tip allows entry through the abdominal wall, and the conduit inside the needle provides a path for insufflation when correctly positioned. The spring-loaded safety mechanism helps shield the tip after entry, reducing the risk of injury to intra-abdominal organs during insertion. This makes it distinct from a trocar with obturator (used to place a cannula), a blunt dissection instrument, or a suction device.
