  • Patent number: 11452647
    Abstract: Apparatus is provided for a medical cutting device, specifically, a cast removal apparatus designed for the removal of orthopedic casts generally applied for immobilization, which apparatus comprises a temperature safety system and/or a burn reduction system. The use of any saw for cast removal creates a potential for patient discomfort and iatrogenic injury, including but not limited to burns which can leave unsightly scars and wound complications. The apparatuses presented comprise a housing for a temperature control system and motor, which motor can be controlled by the temperature control system to control a cast saw blade, with at least one temperature sensor to sense temperature information regarding at least one cutting region of the blade. The temperature information is used by the temperature control system to control the motor. The apparatuses presented comprise a burn reduction system with cast saw blade coolant or lubricant and coolant or lubricant applicators.
