Cutting device

A cutting device for cutting around an anus of an animal comprising:

• a positioning implement to position the cutting device, the positioning implement having at least one surface;
• a cutting implement to cut around the anus, the cutting implement having a cutting edge arranged about the positioning implement;
• a pressure implement comprising a conduit in the positioning implement, the pressure implement opening on a surface of the positioning implement;
• a suction implement comprising a conduit in the positioning implement, the suction implement opening into the space bounded by the cutting implement and the positioning implement wherein the pressure implement and the suction implement extend in an axial direction through the positioning implement and the pressure implement comprises a tube positioned within an axial bore in the positioning implement and the suction implement is bounded by the positioning implement and the axial tube.

A cutting device for cutting around an anus of an animal comprising:

• a positioning implement for positioning the device about the anus of a slaughtered animal;
• a cylindrical knife having a free end, the free end having a cutting edge for cutting around the anus;
• a first pressure conveyance for creating a first pressure within the anus at a distance from the cutting edge;
• and
• a second pressure conveyance for creating a second pressure within a space bounded by the cylindrical knife wherein the first pressure conveyance comprises a tube positioned within the positioning implement and the second pressure conveyance is bounded by the positioning implement and the tube.

A cutting device for arranging a cut around the anus of an animal comprising:

• a rotatable cylindrical knife having a free end and a base, the free end having a cutting edge;
• a pressure conduit extending into a volume bounded by the free end, base and sides of the cylindrical knife, the conduit debounching in the volume, the conduit connectable to a pressure source to generate a pressure at the debounchment;
• and
• a suction conduit extending into the volume bounded by the free end, base and sides of the cylindrical knife, the conduit having an opening in the volume, the conduit connectable to a suction source to generate a suction at the opening wherein the pressure conduit is separate from and extends through the suction conduit thereby permitting the pressure conduit and suction conduit to operate simultaneously.
