Low profile and finger-shaped hook to provide high performance. Minimize the possibility of inadvertent tissue damage with blind port placement. Ensure secure abdominal anchoring by means of cannula retention ridges. Fixation cannula reduces slippage and port migration. Prevent peritoneal tenting due to smooth obturator / cannula transition. Provide minimal fascial trauma and simpler wound closure due to the linear, round bladed design with Mini-Invasive (Only 1 6 mm Abdominal wound puncture.) that reduce force required during insertion. Allow visualisation of instrument introduction through the transparent cannula. Provide leak free instrument exchange by means of an air tight dual seal system. Auto shield with protective tip and red safety indicator. Universal Seal System to allow quick exchange of 5, 10, 12 mm instruments. Special smooth cannula tip design to avoide damage organ. Round blade provides sharp puncture but reduce cutting hurt on tissue. Economy, Safety, Stability and Reliability.
