The trocar KII access systems are indicated in laparoscopic interventions of general, abdominal, gynecological and thoracic minimally invasive surgery, with the purpose of establishing an insertion path or achieving access through tissue planes and / or potential spaces for endoscopic instruments. All components are made of latex-free materials. The trocar access systems are sterile and disposable devices for use in a single patient. Optical trocar access systems use an optical element to visualize the tissue layers during insertion; however, they can be used without visualization for primary or secondary inserts.
