## Abstract

A body has a recess in one surface and within which is disposed a non-circular cutting element retained therein by an epoxy. The non-circular cutting element has its cutting edge formed by beveling its inner surface. The non-circular cutting element extends sufficiently beyond the one surface of the body to be able to penetrate into a face plate, which is utilized with a stoma and in which the non-circular opening is to be cut for use with the stoma of the same shape. A circular template of a clear plastic is removably mounted on the one surface of the body and has a plurality of circles of varying diameters thereon to center the non-circular cutting element relative to a face plate adhesive blank of one of the varying diameters to enable cutting of the same non-circular opening in the adhesive blank. The template has a pair of parallel lines along its circumference to align with a tab on the adhesive blank.

## Claims

### Claim 1

A cutting apparatus for cutting a non-circular opening in a face plate for a non-circular stoma in which the face plate has an annular flange to support a bag of an ostomy appliance including:
a body having a single recess in one surface thereof, said recess having a single continuous peripheral wall;
a non-circular cutting element disposed within said recess and extending a selected distance beyond said one surface of said body;
said body having a circular periphery to center said body relative to an annular flange of a face plate in which a non-circular opening is to be cut by said non-circular cutting element;
said recess in said body having a non-circular shape substantially the same shape as said non-circular cutting element;
said non-circular cutting element having a selected non-circular shape in accordance with the shape of the non-circular stoma with which the face plate is to be used;
said non-circular cutting element having its outer surface straight and its inner surface beveled at its outer end to form the cutting surface of said non-circular cutting element;
and retaining means to permanently retain said non-circular cutting element in its desired position within said recess.

### Claim 2 (depends on 1)

template means to center said non-circular cutting element relative to a face plate adhesive blank in which a non-circular opening is to be cut by said non-circular cutting element;
said template means having an opening in its center through which said non-circular cutting element extends;
said non-circular cutting element extending a selected distance beyond said template means at all times;
and means to releasably secure said template means to said body against said one surface to enable removal of said template means when said non-circular cutting element is to cut a non-circular opening in a face plate.

### Claim 3 (depends on 2)

The cutting apparatus according to claim 2 in which said template means includes a circular element of a transparent material having a plurality of circular lines thereon of selected diameters to center said non-circular cutting element relative to a face plate adhesive blank in which a non-circular opening is to be cut by said non-circular cutting element, each of said circular lines and the edge of said circular element has a diameter corresponding to the diameter of a face plate adhesive blank in which a non-circular opening is to be cut therein by said non-circular cutting element.

### Claim 4 (depends on 3)

The cutting apparatus according to claim 3 including alignment means on said circular element to align said circular element with a tab on a face plate adhesive blank in which said non-circular cutting element is to be cut a non-circular opening at the center thereof.

### Claim 5 (depends on 4)

The cutting apparatus according to claim 4 in which said alignment means includes a pair of substantially parallel lines extending from the edge of said circular element to at least the inner of said circular lines.

### Claim 6 (depends on 5)

The cutting apparatus according to claim 5 in which said retaining means is an epoxy.

### Claim 7 (depends on 4)

The cutting apparatus according to claim 4 in which said retaining means is an epoxy.

### Claim 8 (depends on 3)

The cutting apparatus according to claim 3 in which said retaining means is an epoxy.

### Claim 9 (depends on 2)

The cutting apparatus according to claim 2 in which said retaining means is an epoxy.
