Veress needle

Of the three general approaches to laparoscopic access, the Veress needle technique is the oldest and most traditional.

The tool was first developed in 1932 by János Veres(s) (1903–1979), a Hungarian internist working with tuberculosis patients.

The outer cannula consists of a beveled needle point for cutting through tissues of the abdominal wall.

When the tip of the needle enters a space such as the peritoneal cavity, the dull, inner stylet springs forward.

[7] Several studies have pointed out that for various laparoscopic surgical applications (such as cholecystectomy, groin hernia repairs and appendectomies), creating pneumoperitoneum by using a Veress needle is not always as safe and effective as other techniques (e.g. direct trocar insertion (DTI)).
