Claim Text:
1. A method of performing hand assisted laparoscopic surgery within a surgical cavity, the method comprising the steps of: providing a surgical device comprising a flexible body movable between a collapsed state, in which collapsed state the body is fully insertable, through a surgical incision, into a surgical cavity, and an expanded state, in which expanded state the body is substantially hemispherical in shape and defines an enclosure having at least one opening defined by an open end of the hemispherical body; and an aperture in a sidewall of the body, the sidewall being of double wall construction defining an inflatable cavity therebetween, said sidewall being sufficiently distensible to distend the cavity an amount which will allow hand assisted surgery to be performed within the cavity without the use of insufflation gas in the surgical cavity, and the aperture being shaped and dimensioned, and positioned relative to the opening, to enable the passage of a hand through the aperture to access a surgical site via the opening; passing the device, in a collapsed state, through a surgical incision into the surgical cavity; moving the body into an expanded state by inflating the cavity defined by the double wall sidewall such as to distend the cavity an amount which will allow hand assisted surgery to be performed within the cavity without the use of insufflation gas in the surgical cavity; and passing a hand through the aperture in the sidewall of the body to gain access to the surgical cavity via the opening.
