Problems solved by technology

When doctors locate oral tumors for radiotherapy, they cannot fix the normal organs in the oral cavity well, resulting in excessive irradiation doses for normal tissues that do not need to be irradiated, and the incidence of acute and chronic radiotherapy is relatively high. The scientific oral bracket is inconvenient to adjust the caliber, cannot guarantee a good opening distance, affects the comfort of the patient, and is also inconvenient for the medical staff to operate

Embodiment 1

[0034] Embodiment 1, as a mode of the driving mechanism, further, the driving mechanism includes a second electric telescopic rod 24 fixed on the inner wall of the housing 1, and the output end of the second electric telescopic rod 24 is fixedly installed with a mounting bar 27, and the mounting bar The two ends of 27 are fixedly connected with two movable bars 22 respectively.

[0035] By driving the second electric telescopic rod 24 to work and cooperating with the connecting function of the installation bar 27 , the movable bar 22 can be further driven to move back and forth inside the slide rail 21 .

Embodiment 2

[0036] Embodiment 2, as another way of the driving mechanism, further, the driving mechanism can also include a push-pull bar 28 fixedly installed on the other side of the installation bar 27, the upper surface of the push-pull bar 28 is provided with a chute 31, and the housing 1 A mounting part 30 is fixedly installed at the end of the mounting part 30, and a wedge 29 is installed on the mounting part 30 through a guide bearing, and the wedge 29 is used for one-way limiting of the push-pull bar 28.

[0037] By manually pushing the push-pull bar 28, under the cooperation of the wedge 29 and the chute 31, the movement of the push-pull bar 28 can be unidirectionally limited, which is convenient for manually adjusting the size of the mouth opening.

[0038]Further, the end of the housing 1 close to the support plate 2 is provided with a tongue depressing mechanism for depressing the tongue, the tongue depressing mechanism includes a fixed plate 6, the fixed plate 6 is fixedly ins...

Abstract

The invention discloses an oral cavity support for auxiliary positioning in the oral cavity tumor radiotherapy department, the oral cavity support comprises a shell, the top and the bottom of the shell are respectively provided with a supporting plate, the two supporting plates can open the lips of a patient when being separated from each other, and a transmission mechanism for driving the two supporting plates to move is arranged in the shell. The transmission mechanism comprises a sliding rail fixed to the inner wall of the supporting plate, a movable strip is slidably mounted in the sliding rail, two rotating strips are rotatably mounted on the movable strip, open grooves allowing the supporting plate to penetrate through are formed in the top and the bottom of the shell, and a driving mechanism used for enabling the movable strip to move in the sliding rail is connected to the inner wall of the shell. The two supporting plates move in opposite directions, the opening size of the oral cavity can be adjusted, a good opening distance is provided, and a patient can have good comfort.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an oral bracket for auxiliary positioning in oral tumor radiotherapy department. Background technique [0002] With the continuous update of radiotherapy equipment and the advancement of radiation technology, the survival rate of nasopharyngeal carcinoma has increased significantly, and the prolongation of the survival period has drawn more and more attention to the quality of life of patients. When doctors locate oral tumors for radiotherapy, they cannot fix the normal organs in the oral cavity well, resulting in excessive irradiation doses for normal tissues that do not need to be irradiated, and the incidence of acute and chronic radiotherapy is relatively high. The scientific oral bracket is inconvenient to adjust the caliber, cannot guarantee a good opening distance, affects the comfort of the patient, and is also inconvenient for the medical staff to operate. Cont...
