Individualized stoma base plate cutting method

The invention relates to an individualized stoma base plate cutting method. A stoma measurer is included, the stoma measurer comprises a body of a strip-shaped structure, the body has plasticity, a plug is arranged at one end of the body, a plurality of jacks are formed in the length direction of the body, and the plug is matched with the jacks. An extrusion part matched with a chassis is further arranged at the lower end of the body. The individualized stoma base plate cutting method comprises the steps that S1, a stoma is surrounded by the body, and the side face of the body is attached to the edge of the stoma and shaped; S2, the plug is inserted into the corresponding jacks and locked; and S3, the body is taken down from the stoma, a contour mark used for representing the contour of the stoma is reserved in the cutting area of the chassis through the extrusion part at the lower end of the body, and/or a through hole used for being matched with the contour of the stoma is directly constructed in the cuttin
