[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In the description of the present utility model, it should be noted that for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. Next, the embodiments of the present utility model will be described according to its overall structure.

[0029] In the embodiment of the present utility model, a teaching model device for medical breast surgery includes a torso 1, a breast module one 2 and a breast module two 3. The breast module one 2 and the breast module two 3 are movably connected to the torso 1. The breast module one 2 and the breast module two 3 both include a skeleton structure 4 and a tissue structure 5. The tissue structure 5 is coated outside the skeleton structure 4; it should be noted that the skeleton structure 4 is the mechanical skeleton of this teaching model for supporting the entire breast, but in fact, existing breasts do not have a skeleton structure. In this article, a skeleton is added to support the entire breast.

[0030] Other embodiments of this application: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , through 3D modeling and material selection comparison, this application finally forms a set of medical breast models with a relatively high degree of restoration. The skeleton structure 4 in the model main body composed of the torso 1, the breast module one 2 and the breast module two 3 is specifically the torso of a female with a height of 160 cm and a standard weight below the mandibular line and above the lowest point of the costal arch, and the bony structures and muscle structures such as the cervical vertebra and the thoracic cage are made of hard plastic; the tissue structure 5 is specifically a standard breast shape with a B cup and no sagging, and the skin, fat and mammary gland tissues are made of silicone materials with different hardnesses.

[0031] Moreover, in addition to connecting the breast module one 2 and the breast module two 3, the torso 1 should also reflect the normal anatomical structure as shown in Figure 2 , including the muscles, bones, major nerves, and blood vessels that can be shown by the torso 1.

[0032] Other embodiments of the present application: Please refer to Figure 1 and Figure 2 . As the breast modules in the breast display system of the present application, they should be modules that include the skin, fat, glands, and lesions on their surface or inside, and can be fused into an entire breast. Among them, the material is selected from silicone-like materials. On one side of the breast module one 2, there are areola 21 and nipple 22. The side of the areola 21 away from the breast module one 2 is fixedly connected to the nipple 22. Multiple groups of the areola 21 and nipple 22 respectively correspond to their respective organic diagnosis modules one. The organic diagnosis module one includes modules for nipple inversion, nipple discharge, eczematoid changes of the nipple and areola, and normal nipples; the breast module two 3 includes filler 31 and leather 32. The filler 31 is accommodated inside the breast module two 3, and the leather 32 covers the surface of the breast module two 3. Multiple groups of the filler 31 and leather 32 respectively correspond to their respective organic diagnosis modules two. The organic diagnosis module two includes modules for breast benign tumors without skin changes, breast malignant tumors without skin changes, breast malignant tumors with peau d'orange changes, breast malignant tumors with dimpling sign, and breast abscesses.

[0033] Please refer to Figure 8 and Figure 9 . For the breast conditions diagnosed by the organic diagnosis module two, including

[0034] A. Breast benign tumor module: The skin on the surface of this module usually does not change, and the tumors are set to be multiple. Therefore, a rectangular coordinate system can be established with the nipple as the origin, and the positions in the upper outer, lower outer, upper inner, and lower inner quadrants are respectively defined. The maximum diameters are set to 0.5 cm, 1 cm, 2 cm, and 4 cm respectively. That is, in Figure 9 , the shape of the breast benign tumor can be shown as oval, with clear boundaries, relatively tough texture (similar to the hardness of the nose tip), and good mobility within the breast;

[0035] B. Breast malignant tumor module: The skin on the surface of this module usually does not change. In individual cases as shown in Figure 6 , Figure 9 , Figure 10 and Figure 11 , there may be redness, peau d'orange changes, dimpling sign, ulcer, bleeding, nipple retraction, etc. Among them, the tumors of this module can be set to be multiple, located in the upper outer, lower outer, upper inner, and lower inner quadrants respectively, with maximum diameters of 0.5 cm, 1 cm, 2 cm, and 4 cm respectively. The shape is irregular, the boundaries are not clear, the position is fixed within the breast, and the texture is as hard as the forehead.

[0036] Regarding the breast conditions diagnosed by the organic module one, including the patch 6, the patch 6 is movably connected to the leather 32 and is for the surface of the organic diagnosis module two to diagnose the breast module two 3, and multiple groups of the patches 6 are provided, and each group respectively includes patches for redness and swelling, orange peel-like changes, ulcers and cancer nodules.

[0037] Nipple module: This module is composed of the breast module one 2 and multiple areola 21 and nipple 22 modules. By replacing the areola 21 and nipple 22, this module needs to present disease manifestations such as nipple retraction, nipple discharge, nipple eczema, and neoplasms on the nipple surface;

[0038] Nipple discharge: As Figure 8 shown, the colors of nipple discharge are divided into clear, transparent and colorless, yellow, red or coffee-colored, and milky white, etc., which respectively represent mammary duct dilation, intraductal papilloma of the mammary duct, mammary gland inflammation, and elevated prolactin, etc.;

[0039] Moreover, 15 to 20 ducts of the mammary gland of this module can all open on the nipple surface. With a probe, it can play the function of sensing the nipple and the ducts, and at the same time, the examination process of a ductoscope can be experienced. The appearance of the nipple and areola is normal, and the discharging ducts lead to the milk pore openings. Four discharging ducts (connected to a 0.1 ml capsule at the back) are provided, which respectively represent one of the lesions of mammary duct dilation (the mammary duct is wider than the normal duct), intraductal papilloma of the mammary duct (the mammary duct is wider than the normal duct with multiple small nodules on the inner side wall of the duct), mammary gland inflammation (the duct wall thickens and is locally red and swollen), and elevated prolactin (no obvious change in the duct wall).

[0040] Nipple eczema: Such as Figure 7 shown in Pagets disease, that is, there are eczema-like lesions on the nipple or areola surface of this module, with scabs on the surface, and the local manifestation is the same as that of skin eczema. There may be a mass in the breast. The manifestation of the mass is the same as that of the malignant tumor module.

[0041] Normal breast module: This module shows a breast with no positive findings in terms of appearance and palpation.

[0042] Other embodiments of the present utility model: Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9, this application is modularly designed for different lesion types. The first breast module 2 has a replaceable organic diagnosis module 1, including four modules: nipple retraction, nipple discharge, nipple-areola eczema-like changes, and normal nipples. The second breast module 3 is located in the upper outer quadrant and is also designed with a replaceable organic diagnosis module 2, which is divided into four types of modules: benign breast masses without skin changes, malignant breast masses without skin changes, malignant breast masses with orange peel-like changes, malignant breast masses with dimple sign, and breast abscesses. Among them, different lesion modules are highly simulated to reflect the texture, mobility, boundary, and surface skin changes of tumors. In addition, the nature and color of nipple discharge can also be reflected by the built-in ink.

[0043] The working principle of the present utility model is as follows: The medical high-fidelity breast model developed and designed in this application can reproduce the common clinical manifestations in breast physical examinations in the model, visualize the text content in books, help improve the efficiency of clinical teaching, and at the same time help solve the privacy problem that patients mind in clinical teaching work, and has high clinical application value.

[0044] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
