A cast saw for removing hard orthopaedic bandages, for example formed of plaster is disclosed. The cast saw is a unitary device containing a rechargeable battery pack in a removable filter form collection chamber. A shroud covers at least a portion of the saw blade and such shroud is movable by the cutting operation from the interference of the casting material as the blade is received within the casting material while cutting through such casting material. A dust channel is formed within the housing and dust and debris caused by the cutting operation is pulled through such dust channel by the forces applied by impeller rotated by an electric motor received within the housing. A pressure sensitive switch is supplied which senses an increase in force on the saw blade and increases the current supplied to the motor proportionally in order to provide additional torque to the motor.

Surgical cast cutter

There is disclosed a short leg walker comprising a rigid sole and calf shell and an articulated rigid skin and dorsal shell. The shells are padded at some locations with a non-inflatable padding such as foam or a fiber padding and at other locations with an inflatable bladder and a second bladder between the inflatable bladder and the limb of the patient. The second bladder is responsive to deforming pressure exerted on it and will maintain its support of the limb when the pressure is removed.
