Description

A set of Laparoscopic Trocars and Cannulas, which are fundamental instruments for accessing the body cavity in minimally invasive surgery. A trocar is the sharp, pointed, or bladed instrument used to puncture the abdominal wall, and the cannula is the hollow tube that remains in place after the trocar is withdrawn. The cannula acts as a working port through which other laparoscopic instruments (like the needle holder or scope) can be inserted. The devices shown are reusable metal cannulas, featuring a side-port/stopcock connection for insufflation (introducing CO2​ gas to create working space), and a mechanism at the proximal end to help secure the instruments or seal the port.
