ABSTRACT:
A laparoscopic disk assembly for a Hand Assisted Laparoscopic Surgery (HALS) procedure includes an exteriorly visible laparoscopic disk (seal cap) attached to a retractor skirt. The laparoscopic disk provides an adjustable exterior opening. A downward annular surface is supported by an attached flexible or resilient (“soft) support member that in turn forms an annular contact upon a patient's abdomen wall surrounding an incision to form a sealing connection, to facilitate improved manipulation or degrees of freedom through the laparoscopic disk without loss of insufflation pressure, to minimize, if not eliminate, bruising, to prevent rotation movement of a retractor skirt in the incision, and to reduce fatigue. Versions include a resilient pad, a resilient skirt that adheres to the patient's skin, a skirt with horizontal pleats, and a toroidal bladder that comfortably depresses into the skin.
