Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an auxiliary headrest used for radiotherapy. Background Art

[0002] Radiation therapy is a common method of medical treatment for diseases such as tumors; stereotactic radiotherapy is a special radiotherapy technology that accurately delivers high-dose radiation therapy to extracranial tumor lesions, thereby exposing the tumor to high-dose radiation and normal tissues around the tumor to low-dose radiation. In layman's terms, it is to aim x-rays at a small lesion from multiple angles for concentrated irradiation. Therefore, the location of concentrated irradiation is particularly important for the treatment effect; the radiation therapy head fixation device is a medical device used for body position fixation in radiation therapy. It is mainly used to fix the patient's head during radiation therapy. It can perform precise individualized radiation therapy position fixation according to the body shape of different patients to prevent the patient from moving during treatment and causing treatment position errors. In order to avoid reducing the treatment effect, it is usually clinically ensured that the positioning repeatability of the fractionated treatment is met to meet the clinical error requirements. In the prior art, the commonly used head radiotherapy position fixing device is based on a standardized body frame, on which a headrest and a thermoplastic film for fixing and relaxing the head are installed. For example, patent CN210873764U discloses a radiotherapy individualized headrest molding assembly, which includes a headrest, a molding bracket and a mounting bracket for mounting a thermoplastic mask or a molding bracket. However, the headrest molding assembly does not have a displacement detection or head position detection device. During radiotherapy (especially for stereotactic radiotherapy), since the patient is located in the radiotherapy equipment, it is not convenient for medical staff to directly observe the changes in the patient's head position, which is not conducive to ensuring the accuracy of the patient's head position changes during treatment.

[0027] Example 1, see Figure 1-2 :

[0028] An auxiliary headrest for radiotherapy, comprising a headrest body 1, which is arranged on a mounting panel 2. At least one thin film pressure sensor 3 is arranged between the headrest body 1 and the mounting panel 2. Any thin film pressure sensor 3 is arranged corresponding to the occipital part of the human head. The thin film pressure sensor 3 has a compact structure and has high stability and high-precision pressure monitoring capabilities to ensure the accuracy and reliability of data. At the same time, the pressure sensor has a fast response speed so as to monitor the patient's head position changes in real time. The occipital bone is located behind the base of the skull and is spoon-shaped. Generally, the bone that contacts the pillow when lying flat while sleeping is the occipital bone. The thin film pressure sensor 3 is arranged below the occipital part, which is conducive to the thin film pressure sensor 3 accurately detecting the displacement and rotation of the patient's head.

[0029] The thin film pressure sensor 3 is connected to a controller, and the controller transmits data to a terminal device via a wireless data transmission module.

[0030] As an implementation method, the controller uses a single-chip microcomputer, and the wireless data transmission module is set as a Bluetooth module. Specifically, the single-chip microcomputer uses an STC89C52 single-chip microcomputer, and the Bluetooth module uses an HC-06 Bluetooth module; the wireless transmission between the thin film pressure sensor and the terminal device is realized through Bluetooth technology, which is conducive to simplifying the data transmission process and improving the data transmission efficiency. The terminal device has a display LCD screen, and the display LCD screen of the terminal device can display the pressure data obtained by the thin film pressure sensor 3, so that the doctor can monitor the patient's position changes according to the pressure data. When the pressure data obtained changes greatly, the doctor can suspend the treatment in time, or combine the X-ray image to further judge the patient's head position, and then treat after verification, thereby ensuring the accuracy of the patient's head position during the treatment process; it can be understood that when the terminal device has a data analysis function, it can provide doctors with more accurate and comprehensive data support, which is more conducive to doctors to judge the changes in the patient's head position.

[0031] As an embodiment, the headrest body 1 includes a raised portion 10 for placing the human neck and a head support portion 11 for placing the human head, which is beneficial to ensure the comfort of the patient when lying down. The film pressure sensor 3 is arranged on the lower side of the head support portion 11.

[0032] As an implementation manner, the number of the thin film pressure sensors 3 is set to three, and the three thin film pressure sensors 3 are arranged laterally on the lower side of the head support part 11, and the thin film pressure sensor 3 located in the middle is arranged corresponding to the occipital part of the human head.

[0033] As an embodiment, the height of the raised portion 10 is set to 1.3-1.7 times the height of the head support portion 11. For example, if the height of the head support portion 11 is set to 6 cm, the height of the raised portion 10 is correspondingly set to 9 cm, which is conducive to ensuring the comfort of the headrest body.

[0034] The mounting panel 2 is detachably mounted on the integrated body frame 4 , and a thermoplastic mask 5 is detachably mounted on the integrated body frame. The headrest body 1 is located inside the thermoplastic mask 5 .

[0035] As an implementation mode, fixing holes are formed on both sides of the installation panel 2, and corresponding positioning columns 40 are arranged on the integrated frame 4. When in use, the fixing holes on both sides of the installation panel 2 are aligned with the positioning columns 40 of the integrated frame 4 and can be put on, which is convenient to use.

[0036] The thermoplastic mask 5 includes a U-shaped mounting plate 50, on which a thermoplastic film 51 is provided, a plurality of first mounting holes are formed on the U-shaped mounting plate 50, and second mounting holes are provided on the integrated body frame 4 corresponding to the first mounting holes, and the U-shaped mounting plate 50 is detachably mounted on the second mounting holes through a connecting piece 52.

[0037] Before use, the thermoplastic mask 5 needs to be customized according to the needs of different patients. The conventional thermoplastic mask customization method currently used in hospitals can be used. Specifically, the patient's head is placed on the headrest body 1, and the thermoplastic mask is placed in a 70° constant temperature oven or a constant temperature water pool for heating. The thermoplastic film 51 is taken out after it softens and then contacts the human body through air. The temperature of the thermoplastic film 51 drops rapidly and will not cause harm to the human body. The thermoplastic mask is buckled so that the thermoplastic film adapts to the shape of the patient's head. After standing for 10-15 minutes to set, it can be taken off to complete the customization of the thermoplastic mask 5.

[0038] As an embodiment, the headrest body 1 adopts a latex pillow, which is soft and elastic, can provide good comfort and support, and can reduce the vibration and shaking of the head during radiotherapy, especially for patients who are obese, have tumors and boils in the contact part of the headrest, or have posterior skull protrusion, or in stereotactic radiotherapy of the head, which takes about half an hour. The comfort of the latex pillow is better, which helps to improve the patient's treatment experience. At the same time, in actual use, the latex pillow can be adaptively adjusted according to the actual head shape of the patient to achieve an individualized effect; the mounting panel 2 adopts a plexiglass plate, which is a material commonly used for body frames in hospitals.

[0039] The working principle of this embodiment:

[0040] After the thermoplastic mask 5 is customized, the mounting panel 2 on which the headrest body 1 is arranged is mounted on the integrated body frame 4. The patient lies on the integrated body frame 4 with the patient's head resting on the headrest body 1. The occipital bone of the patient's head is placed correspondingly above the corresponding thin film pressure sensor 3. The thermoplastic mask 5 is buckled down and mounted on the integrated body frame 4 to effectively fix the position of the patient's head. Radiotherapy is then performed, and wireless transmission between the thin film pressure sensor 3 and the terminal device is achieved through Bluetooth technology. The doctor preliminarily judges the change in the patient's head position based on the pressure data obtained by the thin film pressure sensor 3 displayed by the terminal device. When the obtained pressure data changes greatly, the doctor can suspend the treatment in time, or further judge the patient's head position in combination with the X-ray image, and then perform the treatment after verification. This ensures the accuracy of the patient's head position during the treatment process, which is beneficial to ensuring the therapeutic effect of radiotherapy (especially stereotactic radiotherapy).

[0041] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
