[0002] During medical treatment, if a patient has rectal or bladder lesions, in order to save the patient's life, the lesioned part will be removed, leaving a stoma on the body surface. A stoma bag will be placed on the surface of the stoma. The stoma bag is a device that helps the patient collect excrement. The stoma bag is made by cutting. Each stoma is different in size and shape, and the stoma of the required stoma bag is also different. The stoma shape of the stoma patient is not a regular circle, so it is more difficult to cut the stoma bag opening to a size that matches the stoma size.

[0003] In the prior art, a method is often used in which the shape of the stoma is traced with transparent plastic paper, and then covered to the bottom plate and cut after outlining. However, due to operator errors, the cut shape is often opposite to the actual shape, or the angle of the stoma bag is not correct, so that the cut hole cannot match the stoma, etc., and the stoma may be too large or too small, resulting in waste of stoma bags.

[0016] 2. The present invention uses the sliding grooves of the second limit plate and the connecting plate and the moving block to connect with the cutting knife, and the cutting knife can maintain connectivity with the connecting plate and the second limit plate by sliding the moving block along the sliding groove according to the sleeve position of the guide assembly.

When the stoma is shaped according to the patient, the bottom plate is flipped open to facilitate manual adjustment of the positions of the fixed sliding frame and the rotating sliding frame according to the size and shape of the stoma. There are two points inside the fixed sliding frame and the rotating sliding frame, which can be adjusted separately, and these two points are straight lines corresponding to the center of the stoma. According to the shape of the patient's stoma, multiple straight lines are selected, and the rotating sliding frames are rotated to the selected straight lines. The screw is rotated, and the slider moves along the fixed sliding frame and the rotating sliding frame until the bottom of the cone corresponds to the position of the two ends of the stoma straight line. By selecting multiple groups of points, the guide component can roughly simulate the shape of the stoma, provide a path for the movement of the cutting knife, and the fixed sliding frame and the rotating sliding frame are staggered up and down to facilitate rotation and separation, and the bottoms of the two cones at the bottom of each sliding frame are on the same plane, which is convenient for adjustment according to the patient's stoma position. The bottom of the cone does not need to contact the human skin, or a protective cover is set at the bottom of the cone to avoid damaging the human skin. The bottom of the cone is arranged at multiple points on the periphery of the stoma to simulate the shape of the stoma.
