Abstract: A self-propelled cutter has a gear assembly to provide both downward and forward force on a material to be cut. A gear assembly includes a drive input gear that engages with a transfer gear and propulsion gear engaged with the transfer gear by a lever arm. The drive gear and transfer gear are coupled and fixed to the cutter body but the propulsion gear rotates about the transfer gear via the lever arm. This gear assembly enables the propulsion gear to move as required to provide both downward and forward force on a material to be cut, such as a cast. A self-propelled cutter may have a drive input that is coupled with a drive input device, such as a crank or an electric motor. A cutter may have a first gear assembly on a first side of the cutter body and a second gear assembly on a second side.

Abstract: A cast removing tool includes a handle having a battery received therein, and a switch is connected to the handle and electrically connected to the battery. A link is connected to the handle and a motor is connected to the link. The motor has an output shaft which protrudes beyond the link and is connected to a cutting tool. The cutting tool is activated by the motor. A protection member is a curved member and connected to the handle. The protection member extends to be located beneath the cutting tool. The protection member is inserted between the cast and the patient's limb so as to avoid the cutting tool to hurt the patient.

Abstract: A protective system for a cast saw includes a voltage source and a processor coupled to the voltage source. The processor is configured to apply a voltage to a saw blade of a cast saw. The processor is also configured to receive a voltage reading taken across a conductive layer that is at least partially embedded in a cast. The processor is also configured to determine whether the received voltage reading exceeds a threshold voltage. Responsive to a determination that the received voltage exceeds the threshold voltage, the processor is further configured to activate an alarm to warn a user of the cast saw that the saw blade is in contact with the conductive layer.

Abstract: An orthopedic cast removal tool and method uses an unmodified, typically cordless, rotary impact driver and a embedded wire to cut through an orthopedic cast for removal. By merging it with a slotted spacer block specifically for this cast removal purpose, an ergonomic tool is provided which allays fears of orthopedic patients. When rotating and encountering high resistance of the plaster or fiberglass material of the cast, the cordless rotary impact driver does not bog down; since it seamlessly engages impact action, which offers an order of magnitude or more torque multiplication via short frequent pulses (several per second) to overcome this torque resistance. Thus a high amount of torque with very little reaction force is made available to cut through a cast while affording the technician good control. The cast is cut very rapidly with little dust creation and no jostling of the patient.

Abstract: A bandage strip includes a plurality of flat adhesive bandage packages of conventional configuration, having sealed therein an adhesive bandage comprising a pad and an adhesive substrate for adhering to a patient and holding the pad in place on the patient's skin. The packages are adhered to an elongated substrate in end-to-end, spaced relation to form a flat, elongated bandage strip, with perforations in the substrate between the packages. A user can dispense a length of substrate, sever it at the perforations, and remove the bandage from the substrate for use in the conventional manner. In another embodiment, a flat adhesive bandage strip comprises an elongated substrate with at least one continuous strip of absorbent material on one side extending in the elongated dimension of the substrate and an adhesive portion adjacent each outside elongated edge of the substrate, with a release liner adhered to the adhesive portion and covering the pad. In this embodiment a user can cut off a desired length of bandage that is most suited to the application at hand. A bandage dispensing device is attachable to the wrist of a user for convenient dispensing of bandages from a strip of individually packaged bandages.

Abstract: Provided is an ergonomic cutting device for cutting casts and other rigid objects comprising an oscillating cutting blade driven by a motor, a handle, and a vacuum system. The present cutting device is designed such that the offset positioning of the motor enables the weight of the motor to help manipulate and make more efficient the device. The vacuum system cools the device and draws dust produced by the cutting blade through the device without contacting the dust with the motor or other mechanical components. The motor is designed to initially engage in an idle mode when the device is turned on, then automatically sense when a load is placed on the cutting blade and, at that point, boost to a cutting mode. The motor may also be manually placed in a higher powered turbo mode. The device also includes a dynamic braking system which enables the device to stop oscillation of the blade faster than previous device.

Abstract: There is disclosed an instrument for cutting bandages which has a handle and a base guide foot section. The base guide foot has a nose section which extends past the edge of a blade positioned within the instrument. The base guide unit has an enlarged portion on its bottom area which permits the instrument to ride on only a small area and be pivoted on the area when in use. In one version the instruments has a removable blade unit which can be installed and removed without being contacted by the installer thereby reducing possibility of contamination.
