[0002] With the continuous updating of radiotherapy equipment and the advancement of radiation technology, the survival rate of nasopharyngeal carcinoma has been significantly improved. Various acute and late radiation injuries caused by radiotherapy, such as taste and oral mucositis, have also received increasing attention. The introduction of image-guided technology has put forward higher requirements for the level of radiotherapy position fixation in order to obtain better target area repeatability.

[0003] The Chinese utility model patent with application number CN201921347570.2 proposes a special oral bracket for radiotherapy. Through the design of through holes, the upper filling block, middle filling block and lower filling block are formed in one piece, which not only saves the time of medical staff to manually fill the casting material every time, but also further prevents the lower filling block from falling during use. It can also improve the accuracy of radiotherapy for head and neck tumors, limit the displacement of the tongue, protect the taste and oral mucosa, and have a fixing effect. Although this special oral bracket for radiotherapy can position the oral cavity, it requires more complicated coordination, is easy to cause pollution to the oral cavity, and cannot protect the teeth and mouth well.

[0004] Therefore, a radiotherapy positioning device with oral cavity protection is proposed. Utility Model Content

[0028] The protective mechanism is provided with a tongue depressor 5 at the rear end of the device body 1, and the protective mechanism includes guard plates 6 provided at the front of the upper and lower ends of the device body 1;

[0029] The limiting mechanism includes a first tooth groove 7 and a second tooth groove 8 arranged at the rear of the upper and lower ends of the device body 1.

[0030] Specifically, such as Figure 1As shown, the front end face of the device body 1 is set as a boss 2, and the rear end face of the device body 1 is set as a recessed platform 3. The boss 2 and the recessed platform 3 are both set as rounded arc plate structures, and a vent hole 4 is opened at the lower front end of the boss 2.

[0031] By adopting the above technical solution, the device body 1 can be put into the oral cavity, which is conducive to adapting to the oral cavity through the convex platform 2 and the concave platform 3.

[0032] Specifically, such as Figure 2 As shown, a tongue depressor 5 is fixedly connected to the lower rear end of the concave platform 3, and the rear end of the vent hole 4 is arranged in an arc shape.

[0033] By adopting the above technical solution, the tongue depressor 5 can press the tongue, which is beneficial to limit the position of the tongue, prevent the tongue from affecting the placement of the device, and prevent the device from being misplaced.

[0034] Specifically, such as Figure 3 As shown, the front of the upper and lower ends of the device body 1 are fixedly connected with a guard plate 6, and the guard plate 6 is set to an arc-shaped plate structure.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the upper and lower rear ends of the device body 1 are fixed with a first tooth groove 7 and a second tooth groove 8, the first tooth groove 7 is in front of the second tooth groove 8, the first tooth groove 7 and the second tooth groove 8 are both set as rounded arc grooves, nine groups of tooth grooves 9 are evenly opened inside the first tooth groove 7, and seven groups of tooth grooves 9 are evenly opened inside the second tooth groove 8, and the tooth grooves 9 are set as hemispherical grooves.

[0036] By adopting the above technical solution, the upper and lower rows of teeth are inserted into the tooth sockets 9 in the first tooth socket 7 or the second tooth socket 8, so that the device body 1 is fixed in the oral cavity, which is conducive to using the teeth to limit the position of the device body 1 and prevent the device body 1 from sliding around and affecting the treatment. In addition, two types of first tooth sockets 7 and second tooth sockets 8 are provided, which are convenient for adults and children to choose and use.

[0037] After the main body of the device is placed in the mouth, the guard will be placed between the lips and gums, physically separating the lips and gums to form a physical cavity, thereby achieving physical isolation and reducing radiation damage. The tongue depressor rests against the tongue to limit the tongue's position, preventing the tongue from affecting the stability of the device placement, preventing the device from being misplaced, and improving the accuracy of radiation. In addition, the physical cavity formed on the upper part of the tongue forms a physical barrier, reducing radiation damage. The tongue depressor is narrow in front and wide in the back, making the tongue depressor's position on the tongue more stable. The ventilation holes inside the device facilitate ventilation on the one hand, and on the other hand, the physical barrier formed further prevents radiation damage.
