Virat Enterprises - Laparoscopic Trocar Cannula 10mm Stainless Steel Reusable Instruments. A Laparoscopic Trocar Cannula (10mm, Stainless Steel) is a fundamental surgical tool used in minimally invasive laparoscopic procedures. It consists of two main parts: the trocar (sharp or blunt-tipped) used for penetrating the abdominal wall, and the cannula (a hollow tube) through which surgical instruments are introduced into the body cavity. Here are the common uses:1. Access to Abdominal Cavity:The primary use of a trocar cannula is to create access to the abdominal cavity during laparoscopic surgery. The trocar is inserted through the abdominal wall, and the cannula remains in place to maintain access for the introduction of instruments.2. Insertion of Laparoscopic Instruments:Once the trocar is removed, the cannula serves as a conduit through which surgeons can introduce various laparoscopic instruments, such as cameras (laparoscopes), scissors, graspers, or clip applicators, into the surgical field.3. Insufflation:The trocar cannula is often used in conjunction with insufflation to introduce carbon dioxide gas into the abdominal cavity. This creates space for surgeons to visualize and manipulate organs by inflating the abdomen, also known as pneumoperitoneum.
