It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figures 1-5 , the following describes some embodiments of the present application, a 3D printing formed breast cancer prone position treatment positioning device.

[0033] Embodiments of the first aspect of the present application propose a 3D printing formed breast cancer prone position treatment positioning device. In some embodiments of the present application, as shown in Figures 1-5 , the breast cancer prone position treatment positioning device comprises:

[0034] A bottom plate 1 is fixed on a moving platform of a treatment detection device; an upper surface of the bottom plate 1 is sequentially provided with a first support 2, a second support 3 and a third support 4 along a movement direction of the moving platform; along the movement direction, the first support 2, the second support 3 and the third support 4 are used to support at least part of a human body from the head to the feet; a detection cavity 5 is formed between the second support 3 and the third support 4, and the detection cavity 5 is used to accommodate breast tissue of the human body;

[0035] The pressing part is arranged on the upper surface of the bottom plate 1, and comprises a fastening belt 6. The two ends of the fastening belt 6 are fixed between the second support 3 and the third support 4, and the inner surface of the fastening belt 6 and the upper surface of the bottom plate 1 form a fixed cavity 7 for the human body to pass through; the detection cavity 5 is located in the fixed cavity 7; the fastening belt 6 is used for surrounding the rib part and the back of the human body and applying force to the human body; the application direction of the force is perpendicular to the movement direction.

[0036] The 3D printing forming breast cancer prone position device for treatment provided by the present application is firmly fixed on the moving platform of the treatment and detection equipment, provides a stable foundation for the whole device, and ensures that displacement is not generated in the operation process. The first support 2 supports the feet, ensures that the head of the patient in the prone position is well fixed, reduces the pressure on the neck, and provides comfort; the second support 3 supports the upper body, and the design takes into account the natural shape of the female breast, reduces tissue overlap, and improves imaging quality; the third support 4 supports the head, further maintains the overall stability of the patient; the detection cavity 5 formed between the second support 3 and the third support 4 is specially used for accommodating breast tissue. The shape and depth of the cavity are optimally designed to ensure the best position of the breast tissue during detection and treatment, and reduce tissue movement and overlap caused by gravity.

[0037] Through the reasonable design of the support distribution, the device can use gravity to make the breast tissue naturally sag, and the overlap between tissues is reduced to the greatest extent. This design improves the clarity of the image, and makes the lesion more easily identified; the 3D printing technology enables the device to be customized according to the specific body type of the patient, thereby providing more comfortable and accurate support, and adapting to the needs of different patients; due to the proper position of the breast tissue in the detection cavity 5, the imaging system can obtain higher contrast and clarity, thereby improving the accuracy of detection.

[0038] The pressing part is arranged on the upper surface of the bottom plate 1, and comprises a fastening belt 6. The two ends of the fastening belt 6 are fixed between the second support 3 and the third support 4, and the inner surface of the fastening belt 6 and the upper surface of the bottom plate 1 form a fixed cavity 7 for the human body to pass through; the detection cavity 5 is located in the fixed cavity 7; the fastening belt 6 is used for surrounding the rib part and the back of the human body and applying force to the human body; the application direction of the force is perpendicular to the movement direction of the moving platform, which helps to stabilize the breast tissue in the detection cavity 5, and further reduces the tissue overlap caused by movement.

[0039] The force applied by the fastening belt 6 effectively fixes the patient's posture, preventing displacement caused by discomfort or instability during imaging or treatment. This not only improves patient comfort but also ensures imaging quality; the uniform pressure applied by the fastening belt 6 reduces the risk of excessive pressure on local areas, making the patient more comfortable during treatment and improving the stability of the breast tissue in the detection cavity 5; the design of the pressing part coordinates with the bottom plate 1 and the support to ensure that the entire device functions together to achieve the best imaging and treatment effect.

[0040] In summary, by setting the detection cavity 5 to specifically accommodate breast tissue, combined with the reasonable layout of the support, it ensures that the breast tissue is in the best position during detection, reduces tissue overlap caused by body size differences, and improves image clarity; the fastening belt 6 in the pressing part surrounds the rib and back of the human body, and by applying a force perpendicular to the direction of movement, it ensures the stability of the patient during treatment and detection, preventing image blurring caused by body movement; 3D printing technology allows the device to be customized according to the body size of different patients, providing better adaptability and comfort, effectively addressing the impact of physiological differences on detection results.

[0041] In any of the above embodiments, the upper surface of the first support 2 has a first support point, the upper surface of the second support 3 has multiple second support points, and the upper surface of the third support 4 has a third support point; the first support point, the second support point, and the third support point are in contact with the bottom surface of the human body when lying down.

[0042] In the direction of application, all second support points are located between the first support point and the third support point to ensure that the human body lies flat at an inclined angle.

[0043] In this embodiment, the first support point is located on the upper surface of the first support 2, mainly used to support the feet, ensuring the stability of the patient's feet when prone. This support point can help adjust the body posture to keep it on an inclined plane; the second support point is located on the upper surface of the second support 3, and multiple support points are designed to evenly distribute the weight from the upper body. These support points provide effective support for the patient's upper body, preventing discomfort caused by excessive sinking; the third support point is located on the upper surface of the third support 4, which is specially designed to support the head and maintain the correct position of the head and neck. This support point ensures that the patient's spine maintains a natural physiological curve, avoiding additional pressure on the neck and back; all second support points are located between the first and third support points, which ensures that the patient's body lies flat along an inclined angle when prone. Such design helps to maintain the natural posture of the body and enhances comfort; the arrangement of these support points ensures that the force is evenly transmitted through each support point in the direction of the applied gravity, avoiding body displacement or discomfort caused by unstable center of gravity.

[0044] Due to the reasonable design and arrangement of the support points, the gravity applied to the patient can be evenly distributed through each support point, thereby reducing the local high-pressure area and reducing the compression and discomfort of the body. This uniform pressure distribution not only improves the comfort of the patient, but also helps to improve the accuracy of the detection and reduce the movement caused by discomfort; the coordination of the first, second and third support points ensures that the patient remains stable when prone, avoiding the influence of body movement on the positioning of breast tissue. Such stability is crucial for medical detection, which can ensure imaging quality and accuracy and provide more reliable diagnostic basis; the flexibility of the support point design allows the device to adapt to the body structure and size of different patients, ensuring the comfort and cooperation of each patient during the detection process.

[0045] In any of the above embodiments, the upper surface of the second support 3 is provided with an inner arc-shaped groove 301 to accommodate the outward protruding tissue of the patient's abdomen, reducing the compression and overlap with the breast tissue, to adapt to possible obese patients, and all second support points are located on the inner arc bottom surface of the inner arc-shaped groove 301.

[0046] In this embodiment, the design of the recess is specifically for accommodating the outward protruding tissue of the patient's abdomen, especially suitable for patients who may be overweight. This feature ensures that the abdominal tissue has sufficient space and avoids discomfort caused by compression; the presence of the recess can effectively reduce the compression and overlap between the abdominal tissue and the breast tissue, thereby reducing local pressure and improving the comfort of detection; all second support points are arranged on the inner arc bottom surface of the inner arc-shaped recess 301, which ensures that the applied gravity is evenly distributed. When each support point contacts the breast tissue, it can disperse the force and avoid concentrating in one place. The design of the support points allows the breast tissue to remain stable in the recess, reducing tissue displacement caused by patient movement during detection and ensuring the accuracy of imaging.

[0047] The inner arc-shaped recess 301 provides a spacious space that allows the abdominal tissue to be comfortably placed in the recess. The applied body weight is evenly transmitted through all support points, reducing local pressure on the breast tissue and abdominal tissue. This design ensures that each support point can withstand the corresponding force, avoiding discomfort or damage caused by excessive pressure on a single support point; the presence of the inner arc-shaped recess 301 reduces direct contact between the abdomen and the breast tissue, preventing tissue overlap caused by compression, thereby reducing pressure on the breast tissue. This design significantly improves patient comfort, helping them to remain relaxed and calm during detection, and enhancing cooperation.

[0048] In any of the above embodiments, the second support point near the first support 2 is β point, and the second support point near the third support 4 is γ point; β The height of the γ point is higher than that of the

[0049] γ The height of the γ point is higher than that of the third support point, so that the gravity on the breast tissue is biased towards the head of the human body. Since the soft tissue of the abdomen is significantly more than that between the chest and neck of the human body, raising the height of the point higher than the third support point allows the breast tissue to tend to be closer to the neck of the human body, reducing tissue overlap during detection.

[0050] In this embodiment, β The point near the first support 2 has a higher support point. The design of this position allows the supported part to be relatively higher, providing better support to stabilize the foot and help adjust the inclination angle of the upper body. γThe point is close to the third support member 4 and has a relatively low support point position. γ The height of the support point is designed to be higher than the third support point, ensuring that breast tissue tends to move closer to the neck under the influence of gravity; by... β Set the point higher γ Points, and γ The height of the point is higher than that of the third support point, forming a significant height difference. The purpose of this design is to adjust the gravity distribution of the breast tissue so that it can be better positioned in the appropriate location during the detection process, reducing unnecessary overlap. Since there is usually significantly more soft tissue in the human abdomen than in the chest and neck area, this design effectively utilizes the effect of gravity, allowing the breast tissue to naturally sink to a position close to the neck under the influence of gravity, thereby reducing tissue overlap during detection.

[0051] β point, γ The height difference between the first and third support points forms a gravity-guided system. Gravity causes the breast tissue to tilt towards the head when the patient is prone, reducing overlap of the breast tissue. This tilt effectively separates the breast tissue from other soft tissues, ensuring a clearer image during imaging. β Point and γ The height difference design ensures upper body stability in an inclined position, preventing body movement or discomfort caused by uneven weight distribution. This maintains the natural position of breast tissue and improves detection accuracy; by adjusting... γ The height of the dot allows the breast tissue to be positioned closer to the neck, effectively reducing the overlap between the breast tissue and abdominal soft tissue during the examination. This design, which reduces overlap, not only improves image clarity but also increases the doctor's confidence in the results.

[0052] Furthermore, the inner arc-shaped groove 301 is close to β The point is also provided with a lower groove 302, which is used to accommodate the human body's drooping thigh.

[0053] As described above, the inner arc-shaped groove 301 is designed to adapt to the natural curves of the human body, especially the abdomen and thighs. This design effectively accommodates the patient's drooping body parts when lying prone, reducing local pressure and discomfort. A lower groove 302 is located near the β point, specifically designed to accommodate the drooping thigh. The presence of this lower groove 302 ensures sufficient space for the thigh when lying prone, thus avoiding conflict and compression with other support structures. The lower groove 302 effectively supports the thigh, preventing excessive drooping due to gravity, thereby maintaining body stability and improving patient comfort.

[0054] The design of the lower groove 302 can reasonably distribute the gravity applied to the thighs, so that the center of gravity of the thighs remains within the groove, reducing the pressure concentration caused by gravity. This distribution not only reduces local compression, but also improves overall support. The synergy between the lower groove 302 and the inner arc-shaped groove 301 can evenly distribute the gravity of the abdomen and thighs on the contact surface, improving the patient's relaxation experience. The design of the lower groove 302 in combination with the inner arc-shaped groove 301 provides a more comfortable prone position for the patient. Through reasonable groove design, the conflict between different parts of the body can be minimized, avoiding discomfort caused by discomfort. In addition, the height relationship between the lower groove 302 and the β point ensures that the thighs can maintain a natural position when prone, avoiding muscle tension or fatigue caused by excessive sagging. The lower groove 302 makes the entire support system more complete. By accommodating the thighs, the lower groove 302 complements the design of other support components, forming a comprehensive support plan. The coordination of the overall design ensures the stability and comfort of the patient during the detection process, providing a guarantee for the accuracy of the detection results.

[0055] In any of the above embodiments, the inner arc-shaped groove 301 has a lowest point on the inner arc bottom surface ε point, and ε point is lower than γ point to block the abdominal tissue of the human body between the γ point and ε point of the inner arc-shaped groove 301.

[0056] In this embodiment, the design of the inner arc-shaped groove 301 makes the inner arc bottom surface have a lowest point (the ε point), and the height of this point is lower than γ point. This design is used to accommodate abdominal tissue and effectively control its position; ε point is lower than γ point, forming a blocking area between the γ point and ε point, so that the abdominal soft tissue is effectively guided under the action of gravity, avoiding its movement to the breast tissue area; ε The design of the γ point ensures that the abdominal tissue does not pass this lowest point when lying down, and remains between the ε point and ε point. Such a design ensures the stability of the abdominal tissue, which helps to reduce the overlap of the breast tissue during detection; by setting the

[0057] When the patient is prone, gravity causes the abdominal tissue to naturally sink. Because εThe height of the point is lower than γ The abdominal tissues were effectively blocked during the descent. γ Point and ε The design avoids overlap with breast tissue between the dots, ensuring that the breast tissue remains in a relatively independent position during detection, which helps improve the clarity of the image. ε The point design not only restricts the movement of abdominal tissues but also enhances the stability of the entire support structure. This allows patients to maintain a stable posture during the examination, reducing movement caused by discomfort and thus improving accuracy. Simultaneously, keeping the abdominal tissues within a specific area helps improve patient comfort, allowing them to remain relaxed throughout the examination. ε Point and γ The blocking zone between points effectively reduces the overlap between breast tissue and abdominal soft tissue, ensuring a clearer view of the breast tissue during imaging. This is crucial for improving the accuracy and reliability of the detection.

[0058] Furthermore, the top of the first support member 2 is arc-shaped, and the highest first support point is... α point, α The point is the highest point among all points of the first support member 2, the second support member 3, and the third support member 4, and α Points are used to support the lower leg area of ​​the human body.

[0059] As mentioned above, the top of the first support component 2 adopts an arc-shaped design, which better conforms to the natural curve of the human calf. This design not only improves the comfort of the support but also effectively distributes pressure and reduces local discomfort. α The point is the highest point of the first support member 2, the second support member 3, and the third support member 4. α The point design ensures good support for the calf area. This height setting allows the calf area to hang naturally when lying prone, reducing overlap with other soft tissues; α The presence of the point ensures that the lower leg remains stable during the detection process, thus effectively preventing positional changes caused by gravity.

[0060] because α The highest point provides excellent support for the lower leg, keeping the entire lower limb in the correct position. This design ensures even support for the patient in a prone position, improving comfort and safety. The arc-shaped top structure not only supports the lower leg but also effectively reduces contact with the second support component 3, thereby reducing the risk of breast tissue overlap during testing. The arc-shaped design effectively disperses the weight from the upper body, ensuring even distribution of force on the contact surface. This design improves support stability, reduces local pressure concentration, and ensures patient comfort during testing.α The height of the points is coordinated with other support points, which helps to optimize the overall mechanical layout and improve the use effect of the equipment; α The function of the points complements the circular arc design of the first support 2, forming a relatively complete support system. Through reasonable design, the mutual cooperation between the support pieces is ensured, and the functionality of the overall equipment is improved. This coordination ensures that the support of each part of the human body in the prone position is reasonably arranged, minimizing the operational risks caused by discomfort.

[0061] Further, the top of the third support 4 is a plane, and all points on the plane are δ points, and δ The δ points are the lowest points of all points on the first support 2, the second support 3, and the third support 4, and δ The δ points are used to support the face and / or elbow of the human body.

[0062] As mentioned above, the top of the third support 4 is a plane, and all points are δ This design provides a uniform and stable support surface, ensuring that the patient's face and elbows can be well supported, reducing discomfort caused by uneven contact surfaces. The advantage of the plane design is that it can effectively distribute the weight applied to the face and elbows, reducing local pressure, thereby improving patient comfort and stability; δ As the lowest points of the first support 2, the second support 3, and the third support 4, δ The design of the δ points ensures that the face and elbow can be placed naturally when prone, reducing overlap and compression with other soft tissues. Since δ The δ points are located at the lowest position, this design can make the face and elbows maintain a proper angle under the action of gravity, avoiding fatigue or discomfort caused by improper posture.

[0063] δ The plane support of the δ points can provide a stable and comfortable contact surface for the face and elbows. This design reduces displacement caused by gravity, allowing patients to remain stationary during testing, ensuring testing accuracy. Since δ The low design of the δ points can effectively prevent compression of the face and elbows, improving overall comfort experience; the plane top design can effectively distribute the weight applied to the δ points by the upper body, making the pressure on the contact surface evenly distributed, reducing discomfort caused by local pressure concentration, δThe height relationship of the points with other support points forms an optimized mechanical layout, which can make the patient naturally relax in a prone position, avoiding muscle tension or fatigue; the planar design of the third support 4 combined with the shape of the first and second supports 3 forms a coordinated support system. This design ensures that each part of the patient is reasonably supported during the detection process, reducing the risk of tissue overlap, and this coordination improves the overall use effect of the equipment, provides a more comfortable experience for the patient, and improves the effectiveness of the detection.

[0064] In any of the above embodiments, the first support 2, the second support 3 and the third support 4 are all 3D printed, and each has multiple molding types, and can be set as a hollow shell form to accommodate each other between different sizes of molding signals.

[0065] The upper surface of the bottom plate 1 is provided with a jack 101, and the bottom of the side wall of the first support 2, the second support 3 and the third support 4 is integrally formed with a plug-in plate 8, which is inserted with the jack 101 to be replaced and adjusted at any time.

[0066] In this embodiment, the first support 2, the second support 3 and the third support 4 all use 3D printing technology, which can provide multiple molding types according to the body type needs of different patients. This flexibility allows the medical equipment to adapt to patients of different sizes, ensuring comfort and support effect, and the hollow shell form of the support can reduce the overall weight and reduce the burden of the equipment, while providing sufficient strength and stability. This design allows each support to be accommodated by each other, facilitating storage and transportation; the upper surface of the bottom plate 1 is provided with a jack 101, allowing the plug-in plate 8 of different supports to be inserted. This design allows the support to be easily connected to the bottom plate 1 to form a stable overall structure, ensuring the safety and stability of each component during detection, and the bottom of the side wall of the first support 2, the second support 3 and the third support 4 is integrally formed with a plug-in plate 8, which is inserted with the jack 101 of the bottom plate 1. This design not only improves the connection strength of the components, but also simplifies the installation and replacement process, making it easy for medical staff to adjust the configuration of the support at any time as needed.

[0067] The replaceable support produced by 3D printing technology, combined with the design of the socket 101 and the plug plate 8, forms a modular structure. Medical personnel can quickly replace different models of support according to the specific needs of patients to adapt to different body types and treatment needs. This flexible design improves the applicability of medical equipment, enabling it to serve a wider range of patients; the close connection between the socket 101 and the plug plate 8 ensures the stability of the support during use, avoiding displacement or instability caused by poor connection. This design provides higher safety, so that the equipment will not accidentally loosen or shift during detection; through a simple plug-in structure, medical personnel can complete the replacement and adjustment of the support in a short time, greatly improving work efficiency. This convenience is very important for clinical operations, which can improve patient comfort while saving medical time.

[0068] In any of the above embodiments, the second support 3 adjusts the height of the β point and the γ point relative to the first support point and the third support point through a plurality of preset molding models.

[0069] In this embodiment, the second support 3 has a plurality of preset molding models, allowing its height and shape to be adjusted according to different patient needs. This diversity ensures that the support can flexibly adapt to different body types and specific medical requirements; by selecting different molding models, the second support 3 can change β the height of the β point and γ the γ point relative to the first support point and the third support point. This function allows the support to accurately adjust the position of the breast tissue during detection, ensuring optimal imaging results.

[0070] When the model of the second support 3 changes, β the height of the β point and γ the γ point also changes. This fine-tuning of height allows medical personnel to ensure that the breast tissue is in the best position when lying down, avoiding overlapping or discomfort caused by inappropriate height; because different molding models can be selected as needed, the second support 3 provides high adaptability. Patients of different body types can choose the most suitable support model according to their actual needs, ensuring the effectiveness and comfort of the detection process; by accurately adjusting the height of the β β point and γ the γ point, it ensures that the breast tissue is properly positioned under the force of gravity, minimizing overlap with other soft tissues. This optimization not only improves imaging quality, but also allows doctors to make more accurate diagnoses.

[0071] In any of the above embodiments, the bottom plate 1 has a handle 9 fixedly installed on its upper surface, which is used to fix the patient's arm so that the arm and the breast tissue are arranged in different directions along the application direction.

[0072] In this embodiment, the handle 9 is fixed on the upper surface of the base plate 1, and the position is carefully designed to ensure that its relative position with other supporting parts is appropriate.
