This invention relates to a novel surgical medical device of the siliconized, medical grade, gas-sterile type for prolonged examination and applications within the abdominal and thoracic cavity, characterized in that it consists of: an operating "button" and an accessories kit where the operating button is formed by: a transparent or opaque siliconized tube with tip, which facilitates introduction of the device in the abdominal or thoracic wall; an external thread which allows the device to be fixed once it has been introduced into the abdominal wall; an inflatable balloon which, when inflated, functions as a stop preventing the device from being retracted from the inside of the abdominal or thoracic wall; a fixing disc which is provided with a through-hole in its centre allowing it slide along the tube so that it can move towards or away from the inflatable balloon; a valve which is located perpendicularly with respect thereto and which is used to supply air to the balloon so that it inflates when it is situated inside the umbilical wall; a lid used to keep the operating button hermetically sealed; a plunger which acts as a guide, facilitating initial positioning of the device; an adaptor used for fixing peritoneal dialysis or irrigation catheters. The accessories kit is composed of: an adaptor for replenishing with gas; three control discs with through-holes for allowing the passage of 1, 2 or 3 instruments and facilitating manoeuvring; a lid, a ring and a disc made preferably of cellulose impregnated with a wide-spectrum antibiotic which must be positioned between the fixing disc and the abdominal or thoracic wall so as to control the possibility of infection in this area.
