A film of material mountable on a surgical device used for carrying out diagnostic and therapeutic procedures on interior organs of a body, said device comprising a rigid lower blade and a rigid upper blade coupled so as to be spatially adjustable between a closed position and at least one open position;

• said film being made of a flexible and non-stretchable material, for constituting two side walls of the device.

A surgical instrument for carrying out diagnostic and therapeutic procedures on interior organs of a body, the instrument comprising a rigid lower blade and a rigid upper blade each having longitudinal side edges, a handle associated with one of the blades, the other blade being spatially adjustable;

• side walls made of a non-stretchable though pliable material, extending between corresponding side edges of the blades and sized such that at an open position said side walls are tensioned thus, constituting together with the blades a tubular portion through which diagnostic and therapeutic procedures may be carried out.

A vaginal speculum comprising a rigid lower blade and a rigid upper blade, each comprising two side edges and being articulated in a manner so as to be spatially adjustable between a closed position and at least one open position, and two side walls made of a flexible material extending between corresponding side edges of the blades and sized such that at the open position said side walls are tensioned thus forming together with the blades a tubular portion, through which diagnostic and therapeutic procedures may be carried outs and where at a closed position said walls are collapsed and received within a space between the lower blade and the upper blade.
