The absence of any metallic parts is a positive safety factor with respect to electrical risks. The light weight of the trocar combined with a specific thread give excellent stability and cause minimal trauma to the abdominal wall.
The transparent cannula allows the operator maximum visual control. The conical tip with lateral ridge spreads the muscle fibres apart, reducing trauma to the tissues.
The funnel-shaped head to the cannula makes it easier to insert instruments using one hand only. The highly competitive price keeps costs within budget.
