A sterile sleeve assembly made of plastic materials intended to retract a small abdominal incision to allow multiple laparoscopic instruments to pass into the abdomen at the same time during a laparoscopic procedure. It will typically have an introducer that creates the abdominal incision (but is not used in cases where the surgeon chooses to make the incision), and a valve component that maintains the pneumoperitoneum established for the surgical procedure. It allows for the introduction of multiple instruments and/or a camera port, and removal of larger specimens during minimally-invasive laparoscopic surgery. This is a single-use device.
