[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figure 1-Figure 5 , the following describes a 3D printed positioning device for prone treatment of breast cancer according to some embodiments of the present invention.

[0026] The embodiment of the first aspect of the present invention provides a 3D printed positioning device for prone treatment of breast cancer. In some embodiments of the present invention, such as Figure 1-Figure 5 As shown, the positioning device for prone treatment of breast cancer comprises: A bottom plate 1 is fixed on a mobile platform of the treatment detection device; a first support member 2, a second support member 3 and a third support member 4 are sequentially arranged on the upper surface of the bottom plate 1 along the movement direction of the mobile platform; along the movement direction, the first support member 2, the second support member 3 and the third support member 4 are used to support at least part of the human body from the head to the feet; a detection cavity 5 is formed between the second support member 3 and the third support member 4, and the detection cavity 5 is used to accommodate breast tissue of the human body; The pressing part is arranged on the upper surface of the base plate 1; the pressing part includes a fastening belt 6, the two ends of which are located between the second support member 3 and the third support member 4, and the inner surface of the fastening belt 6 and the upper surface of the base plate 1 form a fixed cavity 7 for the human body to pass through, and the detection cavity 5 is located in the fixed cavity 7; the fastening belt 6 is used to surround the ribs and back of the human body and apply a force to the human body; the direction of application of the force is perpendicular to the direction of movement.

[0027] The present invention provides a 3D printed positioning device for prone treatment of breast cancer, wherein the base plate 1 is firmly fixed on the mobile platform of the treatment and detection equipment, providing a stable foundation for the entire device and ensuring that no displacement occurs during operation. The first support member 2 supports the feet to ensure that the patient's head is well fixed in the prone position, reduce the pressure on the neck, and provide comfort; the second support member 3 supports the upper body, and the design takes into account the natural shape of the female chest, reduces tissue overlap, and improves imaging quality; the third support member 4 supports the head to further maintain the overall stability of the patient; the detection cavity 5 formed between the second support member 3 and the third support member 4 is specifically used to accommodate breast tissue. The shape and depth of the cavity are optimized to ensure the optimal position of the breast tissue during detection and treatment, and to reduce tissue movement and overlap caused by gravity.

[0028] Through the rational design of the support distribution, the device can use gravity to make the breast tissue sag naturally, minimizing the overlap between tissues. This design improves the clarity of the image and makes the lesions easier to identify; 3D printing technology enables the device to be customized according to the patient's specific body shape, thereby providing more comfortable and precise support to meet 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 the detection.

[0029] The pressing part is arranged on the upper surface of the base plate 1, and includes a fastening belt 6. The two ends of the fastening belt 6 are fixed between the second support member 3 and the third support member 4, forming a fixed cavity 7 for the human body to pass through; the design of the fixed cavity 7 allows the patient to enter comfortably, while ensuring that the ribs and back of the human body are effectively fixed during the treatment and detection process. This fixation can reduce the movement of the body and ensure the stability of the imaging; the fastening belt 6 surrounds the ribs and back of the human body and applies a downward force to the human body. The direction of application of this force is perpendicular to the movement direction of the mobile platform, which helps to stabilize the breast tissue in the detection cavity 5 and further reduce the tissue overlap caused by movement.

[0030] The force applied by the fastening belt 6 effectively fixes the patient's posture and prevents displacement caused by discomfort or instability during imaging or treatment. This not only improves the patient's comfort, but also ensures the imaging quality; the uniform pressure applied by the fastening belt 6 reduces the risk of local over-pressure, making the patient more comfortable during treatment, while improving the stability of the breast tissue in the detection cavity 5; the design of the pressing part forms a coordinated effect with the base plate 1 and the support member, ensuring that the entire device cooperates with each other in function, thereby achieving the best imaging and treatment effects.

[0031] In summary, the detection cavity 5 is set up to specifically accommodate breast tissue, combined with the reasonable layout of the support parts, to ensure that the breast tissue is in the best position during the detection process, reduce tissue overlap caused by body shape differences, and improve image clarity; the fastening belt 6 in the pressing part surrounds the ribs and back of the human body, and ensures the stability of the patient during treatment and detection by applying a force perpendicular to the direction of movement, thereby preventing image blur caused by body movement; 3D printing technology allows the device to be customized according to the body shape of different patients, providing better adaptability and comfort, thereby effectively addressing the impact of physiological differences on detection results.

[0032] In any of the above embodiments, the upper surface of the first support member 2 has a first support point, the upper surface of the second support member 3 has a plurality of second support points, and the upper surface of the third support member 4 has a third support point; the first support point, the second support point and the third support point fit the bottom surface of the human body when the human body is lying prone.

[0033] Along the application direction, all the second supporting points are located between the first supporting point and the third supporting point to ensure that the human body lies flat at an inclined angle.

[0034] In this embodiment, the first support point is located on the upper surface of the first support member 2, mainly used to support the feet, ensuring the stability of the patient's feet when the patient lies prone. This support point can help adjust the body posture so that it remains on an inclined plane; the second support point is located on the upper surface of the second support member 3, and the multiple support point design can evenly disperse the weight from the upper body. These support points provide effective support for the patient's upper body to prevent discomfort caused by excessive sinking; the third support point is located on the upper surface of the third support member 4, specifically supporting the head to maintain the correct position of the head and neck. This support point ensures that the patient's spine maintains a natural physiological curve and avoids additional pressure on the neck and back; all second support points are located between the first support point and the third support point, and this arrangement ensures that the patient's body lies flat at an inclined angle when lying prone. Such a design helps maintain the body's natural posture and enhances comfort; the layout of this support point ensures that in the direction of the applied gravity, the force is evenly transmitted through each support point to avoid body displacement or discomfort caused by unstable center of gravity.

[0035] 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 local high-pressure areas and reducing squeezing and discomfort to the body. This uniform pressure distribution not only improves the patient's comfort, but also helps to improve the accuracy of detection and reduce movement caused by discomfort; the coordinated effect of the first support point, the second support point and the third support point ensures that the patient remains stable when lying prone, avoiding the positioning of breast tissue due to body movement. Such stability is crucial for medical testing and can ensure imaging quality and accuracy, providing a more reliable basis for diagnosis; the flexibility of the support point design enables the device to adapt to the body structure and body shape of different patients, ensuring the comfort and cooperation of each patient during the test.

[0036] In any of the above embodiments, an inner arc-shaped groove 301 is provided on the upper surface of the second support member 3 to accommodate the protruding tissue of the patient's abdomen and reduce the squeezing and overlapping 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.

[0037] In this embodiment, the groove is designed specifically to accommodate tissue protruding outward from the patient's abdomen, and is particularly suitable for patients who may be overweight. This feature ensures that the abdominal tissue can get sufficient space to avoid discomfort caused by compression; the presence of the groove can effectively reduce the squeezing and overlapping between the abdominal tissue and the breast tissue, thereby reducing local pressure and improving the comfort of detection; all second support points are set on the inner arc bottom surface of the inner arc groove 301. Such a layout ensures that the applied gravity can be evenly distributed. When each support point contacts the breast tissue, it can disperse the force to avoid concentration in one place. The design of the support point allows the breast tissue to remain stable in the groove, reducing tissue displacement caused by patient movement during the detection process, and ensuring the accuracy of imaging.

[0038] The inner arc groove 301 provides a spacious space, allowing the abdominal tissue to be comfortably placed in the groove. The applied body weight is evenly transmitted through all support points, reducing the 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 certain support point; the existence of the inner arc groove 301 reduces the direct contact between the abdomen and the breast tissue, prevents tissue overlap caused by squeezing, and thus reduces the pressure on the breast tissue. This design that reduces squeezing significantly improves the patient's comfort, helps them stay relaxed and quiet during the test, and enhances their cooperation; the design of the inner arc groove 301 can flexibly adapt to the abdominal contours of patients of different body shapes, especially when dealing with overly obese patients, providing the necessary accommodation space to ensure their safety and comfort during the test.

[0039] In any of the above embodiments, the second support point close to the first support member 2 is β Point, and the second support point close to the third support member 4 is c point; β The height of the point is higher than c point.

[0040] c The height of the point is higher than the third support point, so that the gravity on the breast tissue is biased towards the head of the human body. Because the soft tissue in the abdomen of the human body is obviously redundant with the soft tissue between the chest and neck, c The height of the point is higher than the third support point, which can make the breast tissue tend to be closer to the human neck and reduce the overlap of tissue during detection.

[0041] In this embodiment, β The point is close to the first support member 2 and has a higher support point. The design of this position enables the supporting part to be relatively high, providing a better support effect to stabilize the foot and help adjust the inclination angle of the upper body; c The point is close to the third support member 4 and has a relatively low support point position. c The height of the point is designed to be higher than the third support point, ensuring that the breast tissue tends to be closer to the neck of the human body under the action of gravity; β Point set higher than c point, and c The height of the point is higher than that of the third supporting point, forming an obvious height difference. The purpose of this design is to adjust the gravity distribution of the breast tissue so that it can be better located in the appropriate position during the detection process and reduce unnecessary overlap. Since the soft tissue in the human abdomen is usually significantly more than the soft tissue between the chest and neck, 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.

[0042] β point, c The height difference between the first support point and the third support point forms a gravity guidance system. The gravity makes the breast tissue tilt toward the head when lying prone, reducing the overlap of breast tissue. This tilt can effectively separate the breast tissue from other soft tissues, ensuring a clearer image during imaging; β Dot and c The height difference design of the points ensures the stability of the upper body in a tilted position, avoiding body movement or discomfort caused by uneven gravity distribution. This can maintain the natural position of breast tissue and improve the accuracy of detection; by adjusting cThe height of the point makes the breast tissue closer to the neck, which can effectively reduce the overlap between breast tissue and abdominal soft tissue during the detection process. This design of reducing overlap not only improves the clarity of the image, but also increases the doctor's confidence in the results.

[0043] Further, the inner arc groove 301 is close to β A lower groove 302 is also provided at the position of the point, and the lower groove 302 is used to accommodate the drooping thigh of the human body.

[0044] As can be seen from the above, the design of the inner arc groove 301 is intended to adapt to the natural curves of the human body, especially the abdomen and thighs. This design can effectively accommodate the sagging body parts of the patient when lying prone, reducing local pressure and discomfort; a lower groove 302 is provided near the β point, which is specifically used to accommodate the sagging thighs of the human body. The existence of this lower groove 302 can ensure that there is enough space for the thighs when lying prone, thereby avoiding conflicts and compression with other supporting structures. The lower groove 302 can effectively support the thighs and prevent excessive sagging of the thighs due to gravity, thereby maintaining the stability of the body and improving the comfort of the patient.

[0045] The design of the lower groove 302 can reasonably distribute the gravity applied to the thigh, so that the center of gravity of the thigh remains in the groove, reducing the pressure concentration caused by gravity. This distribution not only reduces local compression, but also improves the overall support effect. The synergy between the groove and the inner arc groove 301 can make the gravity of the abdomen and thigh evenly distributed on the contact surface, improving the patient's relaxation experience; the design of the lower groove 302 combined with the inner arc groove 301 provides a more comfortable prone posture for the patient. Through the reasonable groove design, the conflict between the various parts of the body can be minimized to avoid physical discomfort caused by discomfort. In addition, the height relationship between the lower groove 302 and the β point ensures that the thigh can be kept in a natural position when lying prone, avoiding muscle tension or fatigue caused by excessive sagging; the setting of the lower groove 302 makes the entire support system more complete. By accommodating the lower groove 302 of the thigh, the design of other supporting parts complements each other to form a comprehensive support solution. The coordination of the overall design ensures the stability and comfort of the patient during the test process, and provides a guarantee for the accuracy of the test results.

[0046] In any of the above embodiments, the inner arc groove 301 has a e point, and e The height of the point is lower than c point, so as to block the abdominal tissue of the human body in the inner arc groove 301 c Dot and e Between points.

[0047] In this embodiment, the inner arc groove 301 is designed so that its inner arc bottom surface has a lowest point ( e point), and the height of the point is lower than c This design is used to accommodate abdominal tissue and effectively control its position; e The height of the point is lower than c Point, you can c Dot and e A blocking area is formed between the points, so that the soft tissue of the abdomen is effectively guided under the action of gravity to prevent it from moving toward the breast tissue area; e The design of the point ensures that the abdominal tissue does not go beyond this lowest point when lying down, and remains c Point and e This design ensures the stability of the abdominal tissue and helps reduce the overlap of breast tissue during the test. e The point is the lowest point, which can disperse the effect of gravity at this point, reduce the squeeze on the breast tissue, and at the same time provide reasonable support for the abdominal tissue.

[0048] When the patient lies prone, gravity causes the abdominal tissue to naturally sink. e The height of the point is lower than c point, the abdominal tissue is effectively blocked during the sinking process c Dot and e The points are spaced apart to avoid overlapping with breast tissue. This design ensures that the breast tissue remains relatively independent during detection, which helps to improve the clarity of imaging. e The point design not only limits the movement of abdominal tissue, but also enhances the stability of the entire support structure. In this way, the patient can maintain a stable posture during the test, reducing movement caused by discomfort, thereby improving the accuracy of the test. At the same time, the abdominal tissue is controlled in a specific area, which helps to improve the patient's comfort and keep him relaxed throughout the test. e Point and c The blocking area between the points effectively reduces the overlap between breast tissue and abdominal soft tissue, ensuring that the breast tissue maintains a clearer view during imaging. This is crucial to improving the accuracy and reliability of detection.

[0049] Furthermore, the top of the first support member 2 is arc-shaped, and the first support point with the highest height is α point, α 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 The point is used to support the lower leg area of ​​the human body.

[0050] As can be seen from the above, the top of the first support member 2 is designed in an arc shape, which can better conform to the natural curve of the human calf. This design not only improves the comfort of support, but also effectively disperses pressure and reduces local discomfort; α 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 that the calf area is well supported. This height setting allows the calf area to droop naturally when lying prone, reducing overlap with other soft tissues; α The presence of the point keeps the calf area stable during the detection process, thereby effectively preventing position changes caused by gravity.

[0051] because α The point is the highest, which can provide excellent support for the calf, so that the entire lower limb remains in the proper position. This design ensures that the patient's body can be evenly supported in the prone position, improving comfort and safety. The arc-shaped top structure not only supports the calf, but also effectively reduces the contact with the second support member 3, thereby reducing the risk of overlapping breast tissue during the test; the arc-shaped design can effectively disperse the gravity from the upper body, so that the force is evenly distributed on the contact surface. This design improves the stability of the support, reduces local pressure concentration, and ensures the comfort of the patient during the test. α The coordination of the height of the support point and other support points helps to optimize the overall mechanical layout and improve the use effect of the equipment; α The function of the point and the arc-shaped design of the first support member 2 complement each other to form a relatively complete support system. Through reasonable design, the mutual coordination between the support members is ensured, and the functionality of the overall device is improved. This coordination ensures that the support of various parts of the human body can be reasonably arranged in the prone position, minimizing the operational risks caused by discomfort.

[0052] Furthermore, the top of the third support member 4 is a plane, and all points on the plane are d point, and d Point is the lowest point of all points of the first support member 2, the second support member 3 and the third support member 4, and d Points are used to support the face and / or elbow areas of the body.

[0053] As can be seen from the above, the top of the third support member 4 is a plane, and all points are d This design provides a uniform and stable support surface to ensure that the patient's face and elbows are well supported and reduce discomfort caused by uneven contact surfaces. The advantage of the flat design is that it can effectively disperse the gravity applied to the face and elbows, reduce local pressure, and thus improve the patient's comfort and stability; dPoint is the lowest point of the first support member 2, the second support member 3 and the third support member 4, d The design of the points ensures that the face and elbows can be placed naturally when lying prone, reducing overlap and pressure on other soft tissues. d The point is at the lowest position. This design allows the face and elbows to maintain a proper angle under the action of gravity, avoiding fatigue or discomfort caused by improper posture.

[0054] d The flat support of the point can provide a stable and comfortable contact surface for the face and elbow. This design reduces the displacement caused by gravity, allowing the patient to remain still during the test and ensure the accuracy of the test. d The low-position design of the point can effectively prevent the pressure on the face and elbows, and improve the overall comfort experience; the flat top design can effectively disperse the gravity applied by the upper body to the delta point, so that the pressure on the contact surface is evenly distributed, reducing the discomfort caused by local pressure concentration. d The height relationship between the third support member 4 and other support points forms an optimized mechanical layout, which enables the patient to relax naturally in the prone position and avoid muscle tension or fatigue; the plane design of the third support member 4 is combined with the shape of the first and second support members 3 to form a coordinated support system. This design ensures that all parts of the patient are reasonably supported during the test, reducing the risk of tissue overlap. This coordination improves the overall use effect of the equipment, provides a more comfortable experience for patients, and improves the effectiveness of the test.
