Device for cutting out the vent of slaughtered poultry

A device for making an incision around the vent of a slaughtered bird and pulling the end of the rectum out of the opening thus made, comprising:

• a centring pin for insertion into the vent of the bird, which centring pin is movable relative to the bird, and is provided with a thickened end portion;
• and
• a cylindrical rotary cutter with an annular cutting edge, which cutter is movable relative to the bird and is movable coaxially relative to the centring pin,
• the device further comprising:
• one or more holding elements which are recessed relative to the cutting edge and which can cooperate with a contacting surface of the thickened centring pin end portion situated opposite them for holding the vent between these elements and contacting surface near or at the orbicular muscle, wherein said holding elements consist of a principally annular protuberance along the inner circumference of the cutter.
