Visiport Plus RPF Optical Trocar by Covidien

The Visiport Plus optical trocar consists of an obturator with a blunt clear dome at the distal end which encloses a crescent shaped knife blade. When the trigger is squeezed, the blade extends approximately 1mm and immediately retracts. This action permits a controlled, sharp dissection of the tissue layers. The pistol grip handle includes a trigger and, at the proximal end, an opening accommodates a 10mm laparoscope. The Versaport Plus radiolucent trocar sleeve contains an internal seal to prevent gas leakage when instruments are inserted or withdrawn. A Versaport Plus self-adjusting seal, accommodating instruments ranging from 5 mm to 11 mm or 5 mm to 12 mm is designed to effectively reduce the size of the trocar's seal to allow insertion of smaller sized instruments without loss of pneumoperitoneum. There is a 3-way stopcock for gas insufflation and rapid gas desufflation.
