In a pelvic or peritoneal surgical method, a funnel shaped membrane is inserted in a closed configuration through a laparoscopic trocar sleeve into the abdominal cavity of a patient The membrane is spread from the closed configuration to an opened configuration upon emergence of the membrane into the abdominal cavity. The opened membrane and an internal organ of the patient are then positioned relative to one another so that the organ is disposed essentially vertically above the opened membrane. Upon proper positioning, the organ is subjected to a laparoscopic surgical operation while the organ is disposed above the opened membrane, whereby tissue particles and fluid escaping the organ during the operation fall into the opened membrane. The membrane and collected tissue particles and fluid are removed from the abdominal cavity upon termination of the operation.
