A Trocar Cannula, typically measuring 3mm in diameter, is a key component of laparoscopic instruments used in minimally invasive surgery. It consists of a sharp, pointed obturator contained within a hollow tube called a cannula. The obturator is used to puncture the abdominal wall, creating a pathway for the cannula to be inserted into the abdomen. Once in place, the obturator is removed, leaving the cannula in position to provide access for other laparoscopic instruments such as a laparoscope or surgical tools. Trocar cannulas are designed to minimize trauma to the abdominal wall and surrounding tissues while allowing for precise and controlled access during laparoscopic procedures. They are essential for creating the necessary ports through which surgical instruments can be inserted and manipulated inside the body.
