Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a mouthpiece for radiotherapy. Background Technology
[0002] The oral mouthpiece for radiotherapy is an oral cavity positioning device for radiotherapy of head and neck tumors. It can be used in conjunction with thermoformed mesh for the head, neck and shoulders to fix the patient's position, thereby improving the fixation accuracy of the upper and lower jaws and tongue. It can also fix normal tissues as far away from the target area as possible according to the different tumor locations in the head and neck, thereby reducing the occurrence of adverse reactions such as oral mucositis, taste disorders and dry mouth.
[0003] However, during radiotherapy, oral swallowing and involuntary tongue movements can cause the tongue depressor to become unstable, leading to tilting of the tongue depressor during treatment. This can cause the membrane to compress the tongue depressor, resulting in discomfort for the patient.
[0004] To avoid the above situations, oral devices for radiotherapy are often used in clinical practice to reduce oral and tongue movements during treatment. However, existing oral devices for radiotherapy are not adjustable and cannot be used for different patients. If the tongue depressor in the oral device is too short, it will not achieve the ideal tongue fixation effect. If the tongue depressor is too long, the patient's comfort will be insufficient and may even cause vomiting. In addition, oral devices for radiotherapy have poor stability and the fixed position is easy to change. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0030] Example 1
[0031] A mouthpiece for radiotherapy, comprising:
[0032] Tongue depressor 1;
[0033] Mouthpiece 2 is slidably sleeved on the outside of tongue depressor 1;
[0034] An adjustment unit is provided between the tongue depressor 1 and the mouthpiece 2 and is connected to the tongue depressor 1 to adjust the position of the mouthpiece 2 on the tongue depressor 1.
[0035] Connecting plate 3 is connected to the end of tongue depressor 1 that is away from mouthpiece 2;
[0036] The fixing unit has one end connected to the connecting plate 3 in an adjustable relative position, and the other end is bent to fit the chin.
[0037] The above technical solution allows for the adjustment of the position of the mouthpiece 2 on the tongue depressor 1 by the adjustment unit, thereby changing the depth of the tongue depressor 1 inserted into the oral cavity; and further fixation of the radiotherapy mouthpiece by the fixing unit fitting against the patient's chin.
[0038] In this embodiment, the tongue depressor 1 is hollow inside; a first opening 4 is provided on both the first and second sidewalls of the tongue depressor 1; a plurality of second openings 5 are longitudinally spaced on the third sidewall of the tongue depressor 1; one end of the adjustment unit is disposed inside the tongue depressor 1, and the other end passes through the first opening 4 and extends to the outside of the tongue depressor 1; wherein, the first and second sidewalls are arranged opposite to each other, and the third sidewall is disposed between the first and second sidewalls.
[0039] In this embodiment, the adjustment unit includes an adjustment plate 6 and a pressing plate 7; the adjustment plate 6 is disposed inside the tongue depressor plate 1; the first end of the adjustment plate 6 is rotatably connected to the tongue depressor plate 1; the second end of the adjustment plate 6 is connected to the pressing plate 7; one end of the pressing plate 7 away from the adjustment plate 6 passes through the first opening 4 and extends to the outside of the tongue depressor plate 1.
[0040] Among them, such as Figure 1 As shown, the pressing plate 7 can move vertically up and down in the first opening 4, thereby driving the adjusting plate 6 to move up and down in the pressing tongue plate 1.
[0041] In this embodiment, a plurality of springs 8 are also included; the plurality of springs 8 are evenly arranged between the adjusting plate 6 and the tongue depressor plate 1; one end of the spring 8 is connected to the adjusting plate 6 and the other end is connected to the inner wall of the tongue depressor plate 1, so that the adjusting plate 6 moves up and down in the longitudinal vertical direction within the tongue depressor plate 1.
[0042] There are two pressing plates 7, which are respectively located at the second end of the adjusting plate 6 and connected to the adjusting plate 6. The end of the pressing plate 7 away from the adjusting plate 6 passes through the first opening 4 and extends to the outside of the pressing tongue plate 1. The length of the pressing plate 7 is less than the first opening 4 so that the pressing plate 7 can move up and down under the action of the spring 8.
[0043] In this embodiment, the adjusting plate 6 is provided with a plurality of locking blocks 9; the plurality of locking blocks 9 are spaced apart on the adjusting plate 6; one end of the locking block 9 is connected to the adjusting plate 6, and the other end passes through the second opening 5 and extends to the outside of the adjusting plate 6;
[0044] The mouthpiece 2 is slidably fitted onto the outside of the tongue depressor 1 and is limited by the locking block 9.
[0045] With the above technical solution, under the action of spring 8, when medical staff press the pressing plate 7 up and down, the pressing plate 7 slides up and down in the first opening 4, and the second end of the adjusting plate 6 moves up and down around the first end of the adjusting plate 6. At this time, the locking block 9 slides up and down in the second opening 5.
[0046] In this embodiment, the mouthpiece 2 is a trumpet-shaped structure with a gradually widening opening; the opening at the first end of the mouthpiece 2 is smaller than the opening at the second end; a protrusion 10 is connected to the inner wall of the first end of the mouthpiece 2; the gap between the protrusion 10 and the two adjacent locking blocks 9 is adapted to limit the mouthpiece 2.
[0047] Through the above technical solution, the position of the mouthpiece 2 on the tongue depressor 1 is adjusted according to the size of the patient's oral cavity. The pressing plate 7 is pressed down until the locking block 9 is flush with the outer side of the tongue depressor 1, so that the mouthpiece 2 slides along the outer side of the tongue depressor 1. When it slides to the appropriate position, the finger releases the pressing plate 7, and the pressing plate 7 is reset under the action of the spring 8. At this time, the protrusion 10 on the mouthpiece 2 is set in the gap between two adjacent locking blocks 9, and the two adjacent locking blocks 9 limit the mouthpiece 2.
[0048] In this embodiment, the protrusion 10 is annular.
[0049] In this embodiment, the fixing unit includes a fixing plate 11 and an adjusting rod 12; the connecting plate 3 has a connecting hole 13 inside; the first end of the adjusting rod 12 is disposed in the connecting hole 13 and is connected to the connecting plate 3 in an adjustable relative position; the second end of the adjusting rod 12 extends to the outside of the connecting plate 3 and is connected to the fixing plate 11 to form an L-shaped structure.
[0050] Preferably, the fixing plate 11 and the adjusting rod 12 are threaded together; since the length of the chin of different patients is different, the extension length of the second end of the adjusting rod 12 is adjusted by rotating the adjusting rod 12, thereby changing the distance between the fixing plate 11 and the tongue depressor 1 to adapt to the length of the chin of different patients.
[0051] In this embodiment, the second end of the adjusting rod 12 is provided with a sliding groove; the sliding groove is an annular structure; one end of the fixing plate 11 is sleeved on the sliding groove so that the fixing plate 11 rotates around the second end of the adjusting rod 12; the other end of the fixing plate 11 fits against the chin to limit the tongue depressor 1.
[0052] When the fixed plate 11 rotates around the second end of the adjusting rod 12, it encounters a certain resistance and requires external force to achieve the rotation of the fixed plate 11.
[0053] The upper surface of the fixing plate 11 is arc-shaped to fit the patient's chin.
[0054] With the above technical solution, after adjusting the extension length of the second end of the adjusting rod 12, the fixing plate 11 is rotated so that the upper surface of the fixing plate 11 fits against the patient's chin. Then, by adjusting the extension length of the second end of the adjusting rod 12, the tightness of the fit between the fixing plate 11 and the patient's chin is adjusted.
[0055] This utility model provides a mouthpiece for radiotherapy, and the working process of the mouthpiece for radiotherapy is as follows:
[0056] First, adjust the position of the mouthpiece 2 on the tongue depressor 1 according to the size of the patient's mouth, thereby changing the depth of the tongue depressor 1 into the mouth: press down the pressing plates 7 on both sides until the locking blocks 9 are flush with the outer side of the tongue depressor 1, so that the mouthpiece 2 slides along the outer side of the tongue depressor 1. When it slides to the appropriate position, release the pressing plates 7 with your fingers. The pressing plates 7 return to their original position under the action of the spring 8. At this time, the protrusion 10 on the mouthpiece 2 is set in the gap between the two adjacent locking blocks 9, and the two adjacent locking blocks 9 limit the mouthpiece 2. After adjustment, the patient puts the mouthpiece 2 in their mouth, and the tongue depressor 1 is inserted into the mouth to depress the tongue.
[0057] Secondly, adjust the distance between the fixing plate 11 and the tongue depressor 1 according to the length of the patient's chin: by rotating the adjusting rod 12, adjust the length of the extension connecting plate 3 at the second end of the adjusting rod 12, thereby changing the distance between the fixing plate 11 and the tongue depressor 1;
[0058] Finally, rotate the fixing plate 11 so that the upper surface of the fixing plate 11 fits against the patient's chin, and then adjust the tightness of the fit between the fixing plate 11 and the patient's chin by adjusting the extension length of the second end of the adjusting rod 12.
[0059] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
