ABSTRACT:
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.
