ABSTRACT:
A mechanical lift system for use in laparoscopic surgery includes a plurality of suspension members which support the abdominal wall such that the abdominal wall may be mechanically lifted to create a cavity for the scope and the laparoscopic surgery. The suspension members preferably allow bending movement in a first direction, which will be vertically upwardly during the surgical operation, but restricts bending movement in the opposed direction. In this way, the suspension members allow bending movement to conform to the shape of the abdominal wall, but will restrict any such bending movement when the abdominal wall is being lifted by the suspension members. In one preferred embodiment, the suspension members include a flexible strap with a plurality of blocks placed on one face of the strap. When the suspension member is bent with the strap moving away from the blocks, bending is allowed. However, if there is a force tending to bend the straps in a direction toward the blocks, spaced surfaces of the blocks come into contact, preventing further bending movement.
