  • Patent number: 7093603
    Abstract: A skin treating implement, a callus removing hand piece, is used to remove skin calluses. The hand piece is connected to a vacuum suction device. The hand piece has a main body that is bent at a certain degree for greater usability. Below the bend, there is a detachable mount for a cutter with a desired shape. In the upper part of the main body, connectors with nipples can be mounted to be inserted into a suction tube connectable to a vacuum device to ensure compatibility with the suction device. Because the lower portion of the main body of the hand piece is bent, it facilitates removing calluses and permits mounting and unmounting cutters permitting a choice of cutter appropriate for the king of callus to be removed. Connectors with nipples of suitable diameters permit use of suction tubes of existing high-priced vacuum suction devices to make the callus removing hand piece economical. A disposable sheet fixer injection molded with synthetic resins is attachable to the cutter.
