Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breast cancer radiotherapy, in particular to underwear used for radiotherapy after radical surgery of breast cancer. Background Art
[0002] According to the principles of intensity-modulated conformal radiotherapy for tumors, in radiotherapy after radical surgery for breast cancer, in the irradiation direction of the chest wall, the dose distribution shape of the irradiation field must be consistent with the shape of the entire chest wall lesion (target area). However, due to the arc-shaped structure of the chest wall contour and the extremely shallow target area, the dose build-up effect of external irradiation photon energy deposition often makes it impossible to reach the target area dose in superficial areas; at the same time, respiratory movement, heartbeat and other organ movements can easily cause displacement deviations in the target area, resulting in cold areas and off-targets, leading to insufficient doses in the chest wall target area.
[0003] In order to ensure that the chest wall dose reaches the target dose and the uniformity of the overall dose distribution, the existing radiotherapy for patients after radical mastectomy for breast cancer mostly uses additional tissue glue to assist tumor radiation. However, the additional tissue glue is likely to cause a gap between the patient's treatment end and the tissue compensation material during the auxiliary tumor radiotherapy, resulting in poor fitting effect and distortion of dose calculation. In addition, the existing tissue compensation material lacks a specific scale, which makes it difficult to locate and mark the patient's radiotherapy position during radiotherapy, thereby reducing the repeatability between radiotherapy sessions.
[0004] Therefore, we designed a bra for radiotherapy after radical breast cancer surgery. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a bra for radiotherapy after radical breast cancer surgery, which solves the problem that the existing radiotherapy of patients after radical breast cancer surgery mostly uses additional tissue glue to assist tumor radiation. However, due to the additional tissue glue in assisting tumor radiotherapy, a gap is easily formed between the patient's treatment end and the tissue compensation material, resulting in a poor fitting effect and distortion of dose calculation. In addition, the existing tissue compensation material lacks a specific scale, which makes it difficult to locate and mark the patient's radiotherapy position during radiotherapy, thereby reducing the repeatability problem between radiotherapy sessions.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A bra for radiotherapy after radical surgery for breast cancer comprises a main body, a rear end of the main body is provided with a rear placket, a front placket is provided with a front placket at the front end of the rear placket, a hem is provided at the bottom of the front placket, a transverse scale mark is provided at the top of the outward side of the hem, a longitudinal scale mark is provided at the middle position of the front placket away from the rear placket, an armhole is formed at the top of the rear placket and the front placket, a clip is provided at the side of the front placket close to the rear placket, a central axis is provided at the middle position of the side of the front placket away from the rear placket, the longitudinal scale mark is provided at one side of the central axis, a natural latex layer is inserted at one end of the clip close to the front placket, outer plackets are provided on both sides of the front placket, and longitudinal scale marks are provided at the end faces of the outer placket.
[0008] Furthermore, the clip is provided with a reserved notch near the top of one side of the armhole, and the reserved notch is located at one end inside the armhole.
[0009] Furthermore, the clip is offset by 2 centimeters toward a side away from the reserved notch with the central axis as a base point.
[0010] Furthermore, the natural latex layer is detachably connected to the clip via a reserved notch, and the thickness of the natural latex layer is 5 mm.
[0011] Furthermore, the back placket, the front placket and the clip are all made of 95% modal + 5% spandex material.
[0012] Furthermore, an elastic band is provided at the bottom of the rear placket.
[0013] The beneficial effects of the utility model are:
[0014] 1. The utility model can improve the dose of the target area of the chest wall on the affected side (taking the left side as an example) of the patient by padding a 5 mm natural latex layer on the inner side of the underwear. Moreover, since it fits the patient well without any gaps when worn on the patient, distortion of dose calculation can be avoided and repeatability in multiple radiotherapy sessions can be maintained. At the same time, since the midline position of the natural latex layer is offset 2 cm toward the healthy side (right), the 2 cm latex can squeeze the inner breast of the healthy side (right) breast and offset it to the right, thereby increasing the distance between the healthy side (right) breast and the target area on the affected side (left) of the patient, reducing the irradiation dose of the healthy side (right), and reducing the cost to a certain extent.
[0015] 2. The utility model, by setting horizontal and vertical ruler scale lines, uses ruler scales on the lower edge of the front lapel, the center line of the front lapel and the side center line, so as to assist the patient in radiotherapy positioning marking and improve the repeatability between radiotherapy sessions. At the same time, the underwear sizes can be divided into three types: S / M / L, and are divided into left latex type and right latex type to suit different body shapes and left and right breast cancer patients.

[0024] The utility model has a 5 mm natural latex layer 11 on the inner side of the underwear, and covers the outer mid-axillary line all the way, so as to increase the dose of the target area of the left chest wall of the patient. Moreover, when worn on the patient, it fits well without any gaps, thus avoiding distortion of dose calculation and maintaining repeatability in multiple radiotherapy. The density of the natural latex layer 11 is 0.96-0.98, which is close to the water density, that is, the equivalent water density of human tissue. At the same time, the natural latex layer 11 has antibacterial function.
[0025] Please refer to Figure 1 A reserved notch 7 is provided on the top of the armhole 4 on one side of the clip 5, and the reserved notch 7 is located at one end inside the armhole 4. The reserved notch 7 makes it easier to disassemble and assemble the natural latex layer 11 and the underwear, thereby improving the utilization rate.
[0026] Please refer to Figure 1 The clip 5 is offset 2 cm to one side away from the reserved notch 7 with the central axis 8 as the base point. The lower edge of the front lapel 2, the midline of the front lapel 3 and the side midline are provided with horizontal ruler scale lines 10 and vertical ruler scale lines 12, thereby assisting the patient's radiotherapy positioning marking and improving the repeatability between radiotherapy sessions.
[0027] Please refer to Figure 1 The natural latex layer is detachably connected to the clip 5 through a reserved notch 7. The thickness of the natural latex layer 11 is 5 mm. The inner side of this underwear is padded with a 5 mm natural latex layer 11, and it covers all the way to the lower side of the mid-axillary line, thereby increasing the dose to the target area of the patient's left chest wall. Moreover, because it is worn on the patient, it fits well without any gaps, thus avoiding distortion of dose calculation and maintaining repeatability during multiple radiotherapy sessions.
[0028] Please refer to Figure 1 The back placket 2, front placket 3 and clip 5 are all made of 95% modal + 5% spandex.

[0030] In summary, when the utility model is used, step one is to select a radiotherapy underwear according to the underwear model that the patient usually wears and the left and right breast cancer; step two is to wear the underwear and then make a radiotherapy mold and perform CT simulation positioning; step three is to record the scale of the underwear according to the body position and the center point during CT simulation positioning, and the underwear is worn every time the radiotherapy treatment is implemented; and by padding the inner side of the underwear with a 5 mm natural latex layer 11, the dose of the target area of the chest wall on the affected side (taking the left side as an example) of the patient can be increased, and because it is worn on the patient, the fit is very good and there is no gap, which avoids dose calculation distortion and maintains repeatability during multiple radiotherapy. The midline position of the natural latex layer 11 is offset 2 cm to the healthy side (right) side. The 2 cm latex can squeeze the inner breast of the healthy side (right) side breast and offset it to the right side, thereby increasing the distance between the healthy side (right) side breast and the target area on the affected side (left) side of the patient and reducing the irradiation dose of the healthy side (right) side breast, thus reducing the cost to a certain extent. In addition, the lower edge of the front lapel 2, the midline of the front lapel 3 and the side midline are all provided with ruler scales, thereby assisting the patient's radiotherapy positioning marking and improving the repeatability between radiotherapy sessions. At the same time, the underwear sizes can be divided into three types: S / M / L, and are divided into left latex type and right latex type to suit different body shapes and left and right breast cancer patients.
