A retainer to retain the viscera displaced from an internal body area to be accessed for surgery comprises an outer envelope of pliable material with an evacuation port. At least two sheets of material are arranged in face to face relation in the envelope. The sheets have a forming configuration in which they are relatively free to slide over one another in conforming the envelope to a desired shape and a form retained configuration in which the sheets are restrained from sliding relative to one another on evacuation of the envelope. In one case there are sheets of an inelastic material and sheets of an elastic material. Alternatively the sheets may be of the same inelastic material. |
