This utility model discloses a tissue compensator for breast cancer radiotherapy, belonging to the field of breast cancer radiotherapy technology. It includes a compensator body, a teardrop end in the middle of the compensator body, and transition ends connected around the teardrop end, and smooth ends connected around the transition ends. The teardrop end fits into the patient's chest, and the transition ends are curved to facilitate the transition ends fitting into the patient's chest, increasing the tightness of the compensator body fitting into the patient's chest.

Description

Technical Field

[0001] This utility model belongs to the field of radiotherapy guide technology, and in particular relates to tissue compensators for breast cancer radiotherapy. Background Technology

[0002] Tissue compensators for breast cancer radiotherapy are materials used in radiotherapy to increase the radiation dose to the chest wall skin and prevent treatment failure. These compensators are typically made of tissue-equivalent materials and are applied to the chest wall to increase the radiation dose to the superficial target area. However, existing breast cancer radiotherapy tissue compensators are planar, flexible materials. When applied to the breast, some compensators may fold over, potentially causing the compensator to adhere completely to the breast, especially in breasts with larger cup sizes. When the operator applies the compensator to the patient's breast surface, the protruding parts of the breast may push up the middle of the compensator, causing the remaining compensator to adhere to itself, potentially resulting in complete adhesion to the breast. Therefore, we propose a tissue compensator for breast cancer radiotherapy. Utility Model Content

[0003] This invention provides a tissue compensator for breast cancer radiotherapy. By setting the teardrop end to a teardrop shape, it is easy to place the teardrop end on the patient's breast, avoiding the other compensators from folding together and increasing the uniformity of the compensator's fit.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tissue compensator for breast cancer radiotherapy, comprising a compensator body, wherein a water droplet end is provided in the middle of the compensator body, and a transition end is connected around the water droplet end, and a smooth end is connected around the transition end.

[0005] Furthermore, the center of the water droplet is shaped like a water droplet.

[0006] Furthermore, the transition end is positioned such that the water droplet end is shaped like an arc.

[0007] Furthermore, the inner walls of the smooth end, transition end, and teardrop end are all covered with non-woven fabric.

[0008] The beneficial effects of this utility model are:

[0009] This breast cancer radiotherapy tissue compensator features a teardrop-shaped end that conforms to the patient's chest, and an extended transition end that facilitates a close fit to the patient's chest, increasing the tightness of the compensator's fit. Attached Figure Description

[0015] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] Example:

[0017] Please see Figure 1 - Figure 3 A tissue compensator for breast cancer radiotherapy includes a compensator body 1. A teardrop end 13 is located in the center of the body 1, with the center of the teardrop end 13 shaped like a teardrop. Transition ends 12 are connected around the teardrop end 13, with the transition ends 12 shaped like arcs around the teardrop end 13. Smooth ends 11 are connected around the transition ends 12. The compensator body 1 is composed of the smooth ends 11, transition ends 12, and teardrop end 13. The compensator body 1 has a three-dimensional design, allowing the smooth ends 11, transition ends 12, and compensator body 1 to be easily identifiable. The compensator is fitted onto the surface of the patient's breast in a three-dimensional manner. The teardrop end 13 is designed in the shape of a teardrop, so that after the teardrop end 13 is fitted onto the front of the patient's breast, it can fit against the three-dimensional position of the patient's chest. The transition end 12 is arc-shaped and set around the teardrop end 13. After the teardrop end 13 is fitted onto the front of the patient's breast, the teardrop end 13 cannot fold and overlap the transition end 12, reducing the air gap. This prevents the transition end 12 from fitting against the patient's breast, thus increasing the tightness of the compensator body 1 against the patient's breast.

[0018] In other embodiments, the inner walls of the smooth end 11, the transition end 12, and the teardrop end 13 are all covered with non-woven fabric. By covering the inner walls of the smooth end 11, the transition end 12, and the teardrop end 13 with non-woven fabric, the comfort of the smooth end 11, the transition end 12, and the teardrop end 13 when they are attached to the patient's skin is increased.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
