Abstract
The invention belongs to the technical field of radiotherapy equipment, and relates to a water bag-type adjustable bow-shaped bite device; plate, adjustment groove, connecting column, and telescopic rod; a telescopic rod is installed inside the regulating rod, the front end of the telescopic rod communicates with the water bag through the connecting column, the rear end of the telescopic rod communicates with the water pipe, and the two sides of the middle and front part of the regulating rod communicate with the water bag. Slot card slot type connection, the outer end of the adjustment groove is connected with the inner end of the lower support plate, the lower end of the lower support plate is provided with a lower tooth plate, the lower end of the lower tooth plate is provided with a tooth socket, and the lower support plate is inserted into the upper support plate through the cavity connection, the upper end of the upper support plate is provided with an upper dental plate, and the upper end of the upper dental plate is provided with an alveolar; the main structure of the device is reasonable, which ensures an ideal mouth opening, keeps a larger distance between the tumor and normal tissue, and is beneficial to normal tissue The protection of the water bladder and the filling and exhausting of the water bag make the cavity in the oral cavity less, so that the tumor is irradiated with an accurate dose.
Description
Technical field: [0001] The invention belongs to the technical field of radiotherapy equipment, and relates to a mouthpiece with a built-in adjustable water bladder and a tongue depressor and an adjustable opening angle, in particular to a water bladder-type adjustable bow-shaped bite device. Background technique: [0002] Common malignant tumors of the head and neck include nasopharyngeal cancer, oral cavity cancer (buccal mucosa cancer, gingival cancer, mouth floor cancer, hard palate cancer, tongue cancer), oropharyngeal cancer (tonsil cancer, tongue base cancer, soft palate cancer and posterior pharyngeal wall cancer) ), salivary gland tumors, hypopharyngeal carcinoma, laryngeal carcinoma, cervical metastatic carcinoma with unknown primary site, Webster's ring zone lymphoma, nasal NK-t lymphoma, head and neck soft tissue sarcoma, etc. One of the most important treatment methods for head and neck tumors is radiotherapy; in order to avoid damage to normal oral tissues duri...
