Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The first embodiment.

As shown in fig. 1 to 5, a special oral cavity bracket for radiotherapy comprises an occlusion support 1, a pressure plate 2 and a limit breathing channel 3, wherein the pressure plate 2 is arranged at the bottom of one side of the occlusion support 1, the limit breathing channel 3 is arranged in the occlusion support 1 and penetrates through the occlusion support 1, one port of the limit breathing channel 3 is communicated with a tongue depressor, the other port of the limit breathing channel 3 extends out of the other side of the occlusion support 1,

one side top that interlock holds in the palm 1 is close to clamp plate 2 is equipped with filling block 4 and last filling groove 5, and one side below that interlock holds in the palm 1 is close to clamp plate 2 is equipped with down filling block 6 and lower filling groove 7, is equipped with at least one through-hole 8 in the interlock holds in the palm 1, goes up filling groove 5 and link up through-hole 8 and lower filling groove 7, is equipped with well filling block in the through-hole 8, goes up filling block 4, well filling block and lower filling block 6 integrated into one piece. The pressing plate 2 is used for slightly pressing the tongue to limit the displacement of the tongue. The limiting breathing passage 3 is used for facilitating the breathing of the patient. The occlusion support 1 is matched with the upper jaw and the lower jaw of a human body and used for separating and supporting the upper jaw and the lower jaw, the upper filling block 4 and the lower filling block 6 play a role of injection molding in advance and can be directly placed into the mouth of a patient, the upper teeth and the lower teeth in the front of the patient are lightly occluded with the upper filling block 4 and the lower filling block 6 to use, and the effects of saving time and labor are achieved. Lower filling groove 7 is used for holding and establishes filling block 6 down, goes up filling groove 5 and is used for holding and establishes filling block 4, and through-hole 8 is arranged in holding and establishes filling block, goes up filling block 4 when realizing moulding plastics, fills filling block and lower filling block 6 integrated into one piece, and when avoiding the patient to use, the condition that filling block 6 drops takes place down appears, labour saving and time saving facilitates the use.
