Abstract:
1. A surgical device for use in minimally invasive surgery of the type using an inflated body cavity accessible to a surgeon through an access port, defined by the device, surrounding an incision in a patient's body, the device having: body cavity engagement means for insertion into the incision to locate the device in position; fixing means for attaching the device to a patient's skin, the fixing means including a ring; wherein the body cavity engagement means is adjustable by the positioning of the ring so that the positioning of the ring retracts the body cavity engagement means to define an access port and creates a sealing means between the incision and the body cavity engagement means; and additional sealing means incorporating a toroid cell comprising a sealed, non-inflating bladder entirely filled with one of a liquid and a gel to prevent substantial leakage of gas from the body cavity on inflation of the body cavity when the sealing means is in an inoperative position and formed to mould about a substantial portion of a surgeon's hand or surgical instrument on insertion in an operating position.
