[0032] In one embodiment, such as Figure 3 As shown, the red vein body 2, the purple vein body 3, and the surface vein body 4 are all solid structures. Solid structures are simpler to manufacture and help reduce manufacturing costs. In some embodiments, the red vein body 2, the purple vein body 3, and the surface vein body 4 may also be hollow structures.
[0033] In one embodiment, when the red vein body 2, purple vein body 3, and surface vein body 4 are all solid structures, the red vein body 2 and purple vein body 3 can be made of clay, and / or the surface vein body 4 can be made of loofah sponge or orange pith. Clay, loofah sponge, and orange pith are inexpensive to produce, and clay has a rich color palette that eliminates the need for additional color processing. When making the product from clay, simply shape it into the required form. Furthermore, the structure of loofah sponge and orange pith is similar to the morphology of blood vessels, eliminating the need for additional morphological processing. During production, simply dye the loofah sponge and orange pith. In this embodiment, other materials with abundant veins besides loofah sponge and orange pith can also be used. In some embodiments, when dyeing the loofah sponge and orange pith, they can be, but are not limited to, being placed in artificial blood plasma for dyeing, then dried and fixed. In some embodiments, the red vein body 2 and the purple vein body 3 can be made of finer loofah or orange pith, while the surface vein body 4 can be made of coarser loofah or orange pith, or the surface vein body 4 can also be made of clay. In this embodiment, the clay can be ultra-lightweight clay, making the organ model lighter and easier to carry. In some applications, the red vein body 2, the purple vein body 3, and the surface vein body 4 can also be made of other materials.

The red vein body 2 and the purple vein body 3 are integrally set within the sidewall 101 of the model body 1 by the adhesiveness of the clay. When the model body 1, the red vein body 2, and the purple vein body 3 are all made of clay, the red vein body 2 and the purple vein body 3 can be fused with the clay of the model body 1 to a certain extent, forming a gradual transition of color to better match the actual color levels. In some embodiments, the model body 1 can be made of skin-colored clay. Furthermore, a small amount of yellow and white clay can be mixed into certain areas of the skin-colored clay. The resulting model body 1 has richer color levels and is more conducive to evaluation and testing.
[0035] In one embodiment, the surface vein 4 is made of loofah or orange peel, and the model body 1 is made of clay. The surface vein 4 is fixed to the inner surface 102 of the model body 1 by the adhesiveness of the clay, making the fixation of the surface vein 4 to the inner surface 102 of the model body 1 simple. In some embodiments, the surface vein 4 can also be fixed to the inner surface 102 by adhesive after the model body 1 has been shaped. In this embodiment, the model body 1 can also be made of other materials besides clay, whichever is convenient to manufacture.

Then, an uneven structure can be made on the surface of the sphere, and the tumor-like portion 7 can be fixed on the inner surface 102. In another embodiment, the inner surface 102 of the model body 1 is further provided with an erosion portion 5 simulating eroded tissue. The erosion portion 5 can be made by mixing, but is not limited to, a darker red clay with a small amount of white clay. The mixed clay is spread evenly on the inner surface 102 of the model body 1, thereby giving the erosion portion 5 a strong contrast with the normal color of the inner surface 102. The surface of the erosion portion 5 can be made rougher than the normal surface. In one embodiment, the inner surface 102 of the model body 1 is further provided with a flocculent portion simulating flocculent material. In this embodiment, the flocculent portion can be made using, but is not limited to, white fluff.

[0037] In one embodiment, at least a portion of the inner surface 102 of the model body 1 is wavy with uneven texture. The uneven texture better matches the actual skin condition, making the color and brightness of the inner surface 102 of the organ model more consistent with reality, and the image evaluation test more in line with clinical needs.
[0038] In one embodiment, such as Figure 3As shown, the outer surface 103 of the model body 1 is provided with a waterproof adhesive layer 11, which can protect the organ model and facilitate preservation, thereby prolonging the service life of the organ model. In this embodiment, the waterproof adhesive layer 11 can be, but is not limited to, a transparent adhesive layer 10, which can be coated on the outer surface 103 of the model body 1 and cured. In some embodiments, the waterproof adhesive layer 11 and the transparent adhesive layer 10 on the inner surface 102 can be made of the same material and can be processed in the same process.
[0039] In one embodiment, the model body 1 is formed by two halves that are detachably connected. Thus, the model body 1 can be in a state of being folded in two halves, and the two halves can be opened according to needs, thereby providing convenience for evaluation and testing. In this embodiment, the detachable connection can be a clamping connection or a hinged connection. In some embodiments, the two halves can be of the same size or close to the same size. In some embodiments, one half can be configured as a smaller structure in the form of a cover, and the other half can be configured as a larger structure.
[0040] In one embodiment, as shown in Figure 1 The model body 1 is in the shape of a bladder, and the model body 1 is provided with an identification part 8 of the ureteral orifice and a through hole 9 that penetrates the side wall of the model body 1 to simulate the internal urethral orifice. At this time, the organ model is a bladder model, which can have a bladder apex and a bladder base. The through hole 9 can be located at a position above the bladder base, and the endoscope can be inserted into the bladder model through the through hole 9 during evaluation and testing of the endoscope. In this embodiment, the identification part 8 can be in the form of a hole structure that is the same as or similar to the shape of the ureteral orifice, or the identification part 8 can adopt other structures, as long as it can identify the position of the ureteral orifice. For example, the identification part 8 can be a symbol, a groove structure, or a protruding structure provided on the inner surface 102.
[0041] The model body 1 in this embodiment can also be in the shape of other organs, such as the uterus, the renal pelvis, the gallbladder, and the like, which can be provided as needed. The organ model in this embodiment can be made by one or more of handcrafting, injection molding, sculpting, 3D printing, and machining. The organ model in this embodiment is not limited to being applied to evaluation and testing of the image quality of an endoscope, but can also be applied to medical education, surgical training, demonstration and popular science display, and other fields.
