Abstract: This invention provides an enterostomy measurement and stoma base cutting apparatus assembly including a cutting main body and a transparent bottom plate. The cutting main body has a base, a connecting shell, a pressing element, a rotating member, a tool assembly and an elastic element. The connecting shell has a pressing hole and is assembled on a top side of the base, and one side of the pressing element passes through the pressing hole. The rotating member is disposed within a hollow column of the pressing element and is provided with a convex rib. The convex rib is located in a spiral sliding groove inside the hollow column. A plurality of positioning ribs are disposed on a bottom side of the pressing element. The tool assembly is assembled on the bottom side of the pressing element and its position can be adjusted. The elastic element is sleeved outside the hollow column. The transparent bottom plate has a plurality of gauge grooves. Accordingly, a user can place the transparent bottom plate at a position subjecting to the enterostomy to confirm the corresponding gauge groove on the outer edge of the stoma, adjust a cutting blade of the tool assembly to the corresponding positioning rib, and place it on the base to bear a stoma base. After the pressing element is moved downwards under a force, the convex rib causes the rotating member to rotate according to the spiral sliding groove and drives the cutting blade to rotate along the gauge groove to cut the stoma base to form an opening. In this way, the user can quickly and accurately cut the stoma base to form various required sizes of openings without tool replacement. Meanwhile, excellent usability and convenience will be obtained.
