Claim:
A surgical device for application in a treatment performed on the human or animal body to provide access to a surgical site in said body, the device comprising: expansion means ( 1 ) for exerting a force on the organs or tissues at said surgical site; a fluid reservoir ( 2 ); and means ( 3 ) for conveying fluid from said reservoir ( 2 ) to expand said expansion means ( 1 ) through a connection port ( 7 ), the connection port providing access to the internal space of the expansion means ( 1 ), wherein, said expansion means ( 1 ) has elongated expansion members ( 8 ), the expansion members being angled with respect to each other's longitudinal direction in an expanded state, and said expansion members each having opposite ends which are spaced apart in their longitudinal direction, a flexible web ( 12 ) extends between at least two of the expansion members ( 8 ), the at least two expansion members ( 8 ) bordering an open side of the expansion means, the open side i) being void of a web or other closure and ii) configured to provide unrestricted access from an inside of the expansion means to an outside of the expansion means, a pull member ( 14 ) is connected to the opposite ends of at least one of the expansion members ( 8 ), a length of said pull member between said opposite ends being less than a length of said at least one of the expansion members ( 8 ) between said opposite ends so that said at least one of the expansion members ( 8 ), when in the expanded state, is urged by said pull member ( 14 ) to have a slightly curved shape by restricting a full expansion of said at least one expansion member ( 8 ), and the expansion means ( 1 ), during and after expansion thereof, forms a frame with the open side.
