Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a combined breast cancer radiotherapy fixation device. Background Art

[0002] Breast cancer is one of the most common malignant tumors in women. Postoperative radiotherapy is an important part of comprehensive treatment. During postoperative radiotherapy for breast cancer, there are strict requirements for the fixation of the patient's position when irradiating the ipsilateral breast or chest wall and the lymphatic drainage area above and below the clavicle.

[0003] First, the upper limbs and shoulder joints need to be abducted and fixed while avoiding the irradiation field. Breast supports are currently commonly used to achieve this goal, but they have significant drawbacks. Their fixation is poor, and during radiotherapy, slight movements of the patient may cause the position of the upper limbs and shoulder joints to change, affecting the effectiveness of radiotherapy. Furthermore, it is difficult to ensure that the placement of the breast support is completely consistent during each radiotherapy session, resulting in poor repeatability. This can lead to deviations in the irradiation position during each radiotherapy session, making it impossible to accurately irradiate the target area.

[0004] Secondly, fixation of the neck is crucial. Not only must it be well fixed and repeatable, but the patient's position must also be comfortable. This is to ensure the repeatability of the target area, so that each radiotherapy can accurately act on the same area, while protecting important normal tissues, such as the stability of the spinal cord. If only a phantom from the upper limit to the mandible is used, although the chest can be fixed to a certain extent, the fixation effect of the neck is not ideal. If the neck moves during radiotherapy, it may cause the target area to deviate, increase the risk of irradiation to important tissues such as the spinal cord, and cause serious complications.

[0005] Furthermore, for breast cancer patients, postoperative outcomes are categorized as post-radiotomy and post-breast-conserving surgery. For patients undergoing post-radiotomy, the chest wall skin, as a radiotherapy target, can be covered with a fixed phantom, often with a compensating tissue layer to increase the epidermal dose. However, for patients undergoing breast-conserving surgery, the breast skin requires particular protection. This is because the fixed phantom creates a "dose build-up effect" on the breast skin surface, increasing the epidermal dose and, in turn, exacerbating radiation skin reactions, severely impacting the patient's quality of life and subsequent treatment progress.

[0006] In summary, the current existing breast cancer radiotherapy fixation methods cannot fully meet the requirements for patient position fixation during radiotherapy. There is an urgent need for a combined breast cancer radiotherapy fixation device that can solve the above-mentioned problems to improve the accuracy, safety and comfort of radiotherapy. Summary of the Invention

[0007] To overcome existing problems, the present invention provides a combined breast cancer radiotherapy fixation device. A protective net is provided inside the limiting assembly. The protective net has grooves, which can achieve a window effect, exposing the breast skin without affecting the overall fixation. While ensuring that the breast skin is protected, it can still provide stable fixation for the patient, ensure the stability of the patient's position during radiotherapy, avoid the dose build-up effect caused by the breast skin covering the fixation phantom, and reduce the skin reaction to radiotherapy.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A combined breast cancer radiotherapy fixation device includes a base plate made of a high-strength, lightweight, and stable medical-grade material, such as a carbon fiber composite material. The base plate is typically rectangular in shape and designed based on the width and length of a lying human body, capable of stably supporting the patient's body. A support assembly is provided on the upper surface of the base plate, a limit assembly is provided above the support assembly, and a lifting assembly is provided on both sides of the base plate.

[0010] Among them, the limiting assembly and the supporting assembly are detachable structures, and the limiting assembly includes side panels, which are located on both sides of the frame and are made of carbon fiber material. They are connected to the frame through connecting columns, and can limit the sides of the patient's body to prevent the patient from moving sideways during radiotherapy. Connecting columns are passed through the inside of the side panels, and the connecting columns are screwed to the connecting holes and are located on both sides of the supporting assembly. A protective net is provided inside the side panels, and the protective net is installed between the side panels. It is made of medical-grade mesh material with certain elasticity and strength to limit the patient's body as a whole. At the same time, the requirement of exposing the breast skin of patients after breast-conserving surgery is met through the grooves opened. The protective net is provided with a hollow groove at one end of the headrest, and a groove is opened inside the protective net for exposing the breast skin of patients after breast-conserving surgery, and the edges of the groove are rounded.

[0011] Preferably, the lifting assembly includes a connecting seat connected to the base plate. The connecting seat is the part that connects the lifting assembly to the base plate, and its shape matches the through-hole on the base plate. The position of the connecting seat on the base plate can be adjusted according to the needs of different patients. The lower surface wall of the connecting seat is provided with a plug-in column, and the size of the plug-in column is the same as the size of the through-hole. An adjustment column is provided above the connecting seat. The adjustment column is connected between the connecting seat and the curved plate, and adopts a retractable or rotatable structural design for adjusting the height and angle of the curved plate to adapt to the position and posture of the upper limbs of different patients, ensuring the abduction and fixation of the upper limbs and shoulder joints. The adjustment column connects the connecting seat and the curved plate, is retractable or rotatable, is made of hard plastic and has an anti-corrosion treatment on the surface. An curved plate is provided above the adjusting column. The curved plate is located at the top of the adjusting column, is ergonomically shaped, and is made of soft and tough material. A protective pad is provided on the surface wall of the curved plate, which covers the surface of the curved plate and is made of soft, skin-friendly material, such as sponge or foam plastic, to provide a comfortable contact surface for the patient's upper limbs and prevent the upper limb skin from being compressed or abraded.

[0012] Preferably, the support assembly includes a frame, which is the main structure of the support assembly and is located above the base plate. The height and shape of the frame are designed according to ergonomic principles, which can provide comfortable support for the patient and meet the needs of fixing various parts of the patient's body during radiotherapy. Connection holes are provided at corresponding positions of the frame and the side panels. A headrest is provided on the upper surface wall of the frame located on the head, and a scale is provided on the surface wall of the frame. The scale is set on the surface wall of the frame to assist medical staff in accurately adjusting the patient's position and ensure that the patient's body surface marking line is consistent with the back pad scale, thereby ensuring the repeatability of the treatment positioning.

[0013] Preferably, a plurality of through holes are provided at corresponding positions of the base plate and the lifting assembly. The through holes are evenly distributed in the area where the base plate and the lifting assembly intersect, are circular or square in shape, and are designed in size according to the size of the connecting seat. The number and position of the through holes are planned according to the needs of patients of different body shapes to ensure that the lifting assembly can be connected to the through holes at different positions through the connecting seat, thereby adjusting the position of the lifting assembly to adapt to the use of different groups of people.

[0014] The advantages of the embodiments of the present application are:

[0015] 1. A protective net is installed inside the limiting component. The protective net has grooves, which can achieve a window effect, exposing the breast skin without affecting the overall fixation. While ensuring that the breast skin is protected, it can still provide stable fixation for the patient, ensure the stability of the patient's position during radiotherapy, avoid the "dose build-up effect" caused by the breast skin covering the fixed phantom, and reduce the skin reaction to radiotherapy.

[0016] 2. A lifting component is set above the base plate, and a number of through holes are opened at the intersection of the base plate and the lifting component. The lifting component can be flexibly adjusted by connecting with the through holes at different positions to adapt to the body shape differences of different people. The lifting component can not only effectively fix the patient's upper limbs, ensure the abduction of the upper limbs and shoulder joints and avoid the irradiation field, but also its adjustability enables the device to meet the needs of patients of different heights and body shapes, thereby improving the versatility and applicability of the device.

[0017] 3. The surface wall of the support component is equipped with a scale. During radiotherapy, the marking line on the patient's body surface is consistent with the scale of the back pad. This design can ensure the repeatability of treatment positioning. Medical staff can accurately adjust the patient's position according to the scale during each radiotherapy, ensuring that the positioning of each radiotherapy is accurate and correct, improving the accuracy of radiotherapy, enabling radiotherapy to accurately act on the target area while effectively protecting normal tissue.

[0028] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0029] Example

[0030] This embodiment provides a specific structure of a combined breast cancer radiotherapy fixation device, such as Figure 1-5 As shown, the base plate 1 is made of a high-strength, lightweight and stable medical-grade material, such as a carbon fiber composite material. The base plate 1 is generally rectangular in shape and its dimensions are designed based on the width and length of a human body lying flat, so as to stably support the patient's body. The base plate 1 also includes a support assembly 2 provided on the upper surface wall of the base plate 1. A limit assembly 3 is provided above the support assembly 2. A lifting assembly 4 is provided on both sides of the base plate 1 located on the support assembly 2.

[0031] Among them, the limiting component 3 and the support component 2 are detachable structures. The limiting component 3 includes side panels 31. The side panels 31 are located on both sides of the frame 21 and are made of carbon fiber material. They are connected to the frame 21 through connecting columns 33. They can limit the sides of the patient's body to prevent the patient from moving sideways during radiotherapy. Connecting columns 32 are passed through the inside of the side panels 31. The connecting columns 32 are screwed to the connecting holes 24 and are located on both sides of the support component 2. A protective net 34 is provided inside the side panels 31. The protective net 34 is installed between the side panels 31 and is made of medical-grade mesh material with certain elasticity and strength to limit the patient's body as a whole. At the same time, the groove 33 is opened to meet the needs of patients with breast skin exposure after breast-conserving surgery. The protective net 34 is located at one end of the headrest 22 and is provided with a hollow groove 35. A groove 33 for exposing the breast skin of patients after breast-conserving surgery is opened inside the protective net 34, and the edge of the groove 33 is rounded.

[0032] The lifting assembly 4 includes a connecting seat 41 connected to the base plate 1 . The connecting seat 41 is the portion that connects the lifting assembly 4 to the base plate 1 , and its shape matches the through hole 5 on the base plate 1 . The connecting seat 41 can be adjusted to its position on the base plate 1 according to the needs of different patients. A plug-in column is provided on the lower wall of the connecting seat 41, and the size of the plug-in column is the same as the size of the through hole 5. An adjustment column 42 is provided above the connecting seat 41. The adjustment column 42 is connected between the connecting seat 41 and the curved plate 43. It adopts a retractable or rotatable structural design for adjusting the height and angle of the curved plate 43 to adapt to the position and posture of the upper limbs of different patients, ensuring the abduction and fixation of the upper limbs and shoulder joints. The adjusting column 42 connects the connecting seat 41 and the curved plate 43, and is retractable or rotatable. The material is hard plastic and the surface is anti-corrosive treated. A curved plate 43 is provided above the adjusting column 42. The curved plate 43 is located at the top of the adjusting column 42, is ergonomically shaped, and is made of soft and tough material. A protective pad 44 is provided on the upper wall of the curved plate 43. The protective pad 44 covers the surface of the curved plate 43 and is made of soft, skin-friendly material, such as sponge or foam plastic, providing a comfortable contact surface for the patient's upper limbs to prevent the upper limb skin from being compressed or abraded.

[0033] The support assembly 2 includes a frame 21, which is the main structure of the support assembly 2 and is located above the base plate 1. The height and shape of the frame 21 are designed according to ergonomic principles, which can provide comfortable support for patients and meet the needs of fixing various parts of the patient's body during radiotherapy. Connection holes 24 are provided at corresponding positions of the frame 21 and the side panels 31. A headrest 22 is provided on the upper surface wall of the frame 21 located on the head, and a scale 23 is provided on the surface wall of the frame 21. The scale 23 is set on the surface wall of the frame 21 to assist medical staff in accurately adjusting the patient's position and ensuring that the patient's body surface marking line is consistent with the back pad scale, thereby ensuring the repeatability of the treatment positioning.

[0034] Several through holes 5 are provided at the corresponding positions of the base plate 1 and the lifting component 4. The through holes 5 are evenly distributed in the area where the base plate 1 and the lifting component 4 intersect. The shape is circular or square, and the size is designed according to the size of the connecting seat 41. The number and position of the through holes 5 are planned according to the needs of patients of different body shapes to ensure that the lifting component 4 can be connected to the through holes 5 at different positions through the connecting seat 41, thereby adjusting the position of the lifting component 4 to adapt to the use of different people.

[0035] By adopting the above technical solutions:

[0036] On the day of radiotherapy, the patient lies on the base plate 1 of the fixation device, with the head naturally placed on the headrest 22. The medical staff fine-tune the height and angle of the headrest 22 according to the physiological curve of the patient's neck to ensure that the patient's neck is comfortable and well fixed.

[0037] Next, the medical staff observes the patient's body shape, selects the through hole 5 at the appropriate position, and fixes the connecting seat 41 of the lifting component 4 on the through hole 5. Then, the adjusting column 42 is adjusted so that the arc plate 43 supports the patient's upper limbs, ensuring that the upper limbs and shoulder joints are abducted to the appropriate angle, and the protective pad 44 fits comfortably with the patient's upper limb skin to avoid skin pressure.

[0038] Afterwards, the medical staff connects the side panels 31 of the limiting assembly 3 to the frame 21 through the connecting columns 32, so that the protective net 34 can limit the side of the patient's body. In particular, the medical staff carefully aligns the patient's breast with the groove 33 on the protective net, allowing the breast to be exposed through the groove 33, while ensuring the fixing effect of the protective net 34 on other parts of the body.

[0039] After completing the above operations, the medical staff observes the patient's body surface marking line and the scale 23 on the surface wall of the support component 2, and fine-tunes the patient's body position to ensure that the body surface marking line is completely consistent with the scale.

[0040] During the entire radiotherapy process, the patient felt relatively comfortable, and the upper limbs, neck and body as a whole were well fixed. Since the breast skin was exposed through the groove 33, the "dose build-up effect" was avoided, and the skin reaction after radiotherapy was mild. After the radiotherapy was completed, the medical staff loosened the fixation device according to the steps and assisted the patient to leave.

[0041] Working principle:

[0042] Before the patient undergoes radiotherapy, the medical staff first helps the patient lie on the base plate 1, so that the patient's body is located in the frame 21 and the head is placed on the headrest 22. The height and angle of the headrest 22 are adjusted to ensure that the patient's neck is in a comfortable and fixed position.

[0043] According to the patient's body shape, select the through hole 5 at the appropriate position, connect the connecting seat 41 of the lifting component 4 to the through hole 5, and then adjust the height and angle of the adjustment column 42 so that the arc plate 43 can accurately lift the patient's upper limbs, ensuring that the upper limbs and shoulder joints are abducted to the appropriate angle and fixed. At the same time, ensure that the protective pad 44 is in good contact with the patient's upper limb skin to avoid skin pressure.

[0044] The side panels 31 of the limiting assembly 3 are connected to the frame 21 through the connecting columns 32, and the positions of the side panels 31 are adjusted so that the protective net 34 can limit the sides of the patient's body. For patients undergoing breast-conserving surgery, the patient's breast is aligned with the groove 33 on the protective net 34 so that the breast is exposed through the groove 33, while ensuring the fixing effect of the protective net 34 on other parts of the patient's body.

[0045] The medical staff observes the patient's body surface markings and the scale 23 on the surface of the support assembly 2, and fine-tunes the patient's position to ensure that the body surface markings are consistent with the scale to ensure repeatability of the treatment position. Throughout the process, pay attention to the patient's comfort and make timely adjustments if any discomfort occurs.

[0046] After completing the above operations, the patient can undergo radiotherapy. During the radiotherapy process, medical staff can observe the patient's physical condition through the hollow groove 35 to ensure that the patient's position is stable and make appropriate adjustments if necessary.

[0047] After radiotherapy is completed, the medical staff first loosens the connection between the lifting component 4 and the base plate 1, moves the lifting component 4 away, then unties the connection between the limiting component 3 and the frame 21, assists the patient to leave the fixture, and cleans and disinfects the fixture for next use.

[0048] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
