[0022] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 3As shown, the auxiliary positioning device for tumor radiotherapy includes a positioning body 1, the top of the positioning body 1 is provided with an upper groove body 11 matching the physiological curvature of human teeth, the bottom of the positioning body 1 is provided with a lower groove body 12 matching the physiological curvature of human teeth, a tongue depressor 2 is slidably provided in the middle of the positioning body 1, and a locking component 3 for locking or releasing the tongue depressor 2 and the positioning body 1 is provided on the positioning body 1; in this embodiment, the patient bites on the upper and lower sides of the positioning body 1 by the upper and lower teeth corresponding to the upper groove body 11 and the lower groove body 12 respectively, and positions the oral opening, and at the same time, the end of the tongue depressor 2 can press and fix the patient's tongue; the length of the tongue depressor 2 inside the patient's oral cavity can be adjusted according to the actual situation of the patient to match different users. After the length of the tongue depressor 2 is adjusted, the tongue depressor 2 can be locked and fixed to the positioning body 1 by the locking component 3; since the tongue depressor 2 can be adjusted to meet the use of different patients, it can be mass-produced to reduce the production cost, and can be directly taken out when used, adjusted to fit the patient, and can be used, which is convenient to use.

[0024] A slideway 14 is provided in the middle of the positioning body 1, and one end of the tongue depressor 2 is slidably arranged inside the slideway 14. The locking component 3 is a hand-tightening bolt 31 arranged above the slideway 14, and the end of the hand-tightening bolt 31 corresponds to the tongue depressor 2 inside the slideway 14. By screwing the hand-tightening bolt 31, the end of the hand-tightening bolt 31 abuts against or separates from one side of the tongue depressor 2 in the slideway 14, thereby realizing the locking or release between the tongue depressor 2 and the positioning body 1.

[0025] The top of the positioning body 1 is provided with a groove 13 on the outer side which matches the hand-tightening bolt. The hand-tightening bolt 31 is threadedly arranged inside the groove 13. The top of the hand-tightening bolt 31 is embedded in the groove 13. The external threaded rod of the hand-tightening bolt 31 is threadedly connected to the part of the positioning body 1 below the groove 13. The setting of the groove 13 can prevent the hand-tightening bolt 31 from contacting the patient's lips at the top protrusion of the positioning body 1, thereby ensuring comfort.

[0026] An opening 131 is formed at one side of the groove 13 , and the opening 131 allows a portion of the upper end of the hand bolt 31 to be exposed to the outside, making it easier to rotate the hand bolt 31 .

[0027] like Figure 3 As shown, the tongue depressor 2 has a sliding connecting plate 22 , one end of which is provided with a bending portion 21 which is an integral structure therewith, and the sliding connecting plate 22 is slidably arranged inside the slideway 14 .

[0028] The tongue depressor 2 has rounded corners around it, and the rounded corners can prevent the edges and corners around the tongue depressor 2 from scratching the patient's oral cavity.

[0029] The positioning body 1, the tongue depressor 2 and the locking component 3 are all an integrated structure made of polylactic acid.

[0030] The length of the tongue depressor 2 is 8-10 cm, the width of the tongue depressor 2 is 2-3 cm, and the length of the tongue depressor 2 is 0.2-0.5 cm.

[0031] The above is a preferred implementation mode of the utility model. Technical personnel in this industry should understand that the implementation mode of the utility model is not limited by the above content, and any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the utility model should be equivalent replacement methods and are included in the protection scope of the utility model.
