Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breast radiotherapy, in particular to a breast radiotherapy fixing device. Background Art
[0002] The development of modern medicine has gradually made it a reality for humans to control and conquer cancer. In the clinical treatment of tumors, surgery, radiotherapy and chemotherapy are the three main treatment methods. Radiotherapy has a wide range of indications and is highly selective. More than 70% of malignant tumor patients need to receive radiotherapy at some stage of their treatment. The purpose of radiotherapy is to maximize the concentration of radiation dose in the lesion area (target area) to kill tumor cells, while the surrounding normal tissues or trachea are less or free from unnecessary irradiation. Some important organs such as the brainstem, lens, spinal cord, kidney, gonads, etc. require special protection. Traditional radiotherapy technology is only the initial stage of achieving this goal. While curing tumors, it also brings one-time or permanent damage to normal tissues and organs. Breast radiotherapy technology is becoming more and more mature, but the existing fixed positioning device for breast radiotherapy is not convenient to adjust and is relatively bulky as a whole, resulting in poor use effect.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0024] The following describes an embodiment of the utility model based on its overall structure.
[0025] A breast radiotherapy fixation device, such as Figure 1-5 As shown, a threaded hole 8 is provided on the left side of the hollow frame 6 and passes through the right side of the hollow frame 6, and a second threaded rod 9 is passed through the threaded hole 8, an extension head 10 is provided on the right end of the second threaded rod 9, and a hollow cylinder 11 is provided on the outer side of the extension head 10, the hollow cylinder 11 is connected to the extension head 10 by a screw 12, and a bearing 13 is connected to the right outer side of the hollow cylinder 11, a first fixing block 14 is provided on the right end of the bearing 13, a cushion 15 is provided on the inner side of the first fixing block 14, and a second fixing block 16 is provided on the right side of the first fixing block 14, a limiting rod 17 is provided between the second fixing block 16 and the inner side of the first fixing block 14, and the front and rear sides of the second fixing block 16 are connected to the first fixing block 14 by a third threaded rod 18, rotating the second threaded rod 9 allows the position of the first fixing block 14 and the second fixing block 16 to be adjusted, so that the fixed position is more accurate, and rotating the third threaded rod 18 allows the first fixing block 14 and the second fixing block 16 to adjust the space between them, which has a better effect on the fixation of the breast radiotherapy position.
[0026] See also Figure 1 and Figure 3The lower end of the limit frame 1 passes through the upper side of the limit frame 1 and is connected to a first threaded rod 2, and a limit block 3 is installed on the top of the first threaded rod 2. The limit block 3 is arranged inside the limit frame 1, and an anti-slip pad 4 is arranged on the upper side of the limit block 3. When the limit frame 1 is installed to the side of the bed, the first threaded rod 2 is rotated, and the limit frame 1 can be fixedly installed on one side of the bed through the action of the limit block 3 and the anti-slip pad 4, so that the breast radiotherapy treatment work progresses better.
[0027] See also Figure 1 and Figure 3 A fixing plate 5 is provided on the upper side of the limiting frame 1, and a hollow frame 6 is provided on the outer side of the fixing plate 5. At the same time, the hollow frame 6 is connected to the fixing plate 5 through a fixing component 7, so that the height of the hollow frame 6 is convenient to adjust, thereby allowing the height of the first fixing block 14 and the second fixing block 16 to be adjusted.
[0028] See also Figure 1 , Figure 2 and Figure 5 The shape and size of the first fixing block 14 are respectively the same as the shape and size of the second fixing block 16, so that it has a better limiting effect on the breast radiotherapy site.
[0029] See also Figure 1 , Figure 2 and Figure 5 A soft pad 15 is provided on the inner side of the second fixing block 16 to protect the breast when the radiotherapy site is fixed.
[0030] The working principle of the utility model is as follows: when in use, by allowing the limit frame 1 to be installed on the mounting frame on one side of the bed, the first threaded rod 2 is started to be rotated at this time, and the first threaded rod 2 drives the limit block 3 to rotate, so that the limit block 3 can move up to fix the limit frame 1, and through the effect of the anti-slip pad 4, the fixing stability of the limit frame 1 is better, and the height of the hollow frame 6 is adjusted at this time, and the hollow frame 6 is moved upward by pulling the hollow frame 6. After the height adjustment is completed, the fixing component 7 is used to fix the hollow frame 6 and the fixing plate 5. At this time, the second threaded rod 9 is started to be rotated, and the second threaded rod 9 is rotated inside the threaded hole 8 on the hollow frame 6, so that the first fixing block 14 and the second fixing block 16 can be moved laterally to adjust the fixed position. After the adjustment is completed, the distance between the first fixing block 14 and the second fixing block 16 can be adjusted, and the third threaded rod 18 can be rotated so that the second fixing block 16 and the first fixing block 14 can better fix the patient's breast radiotherapy site, and at the same time, through the protection of the soft pad 15, unnecessary harm to the patient is avoided.
