Abstract
The utility model provides a special mouth plug for radiotherapy. The special mouth plug consists of a locating rod, a mouth plug center shaft, a tooth biting layer, a mouth plug body, a bottom surface of the mouth plug, and an upper edge of the mouth plug, wherein the locating rod is arranged on the upper edge of the mouth plug, the mouth plug center shaft is connected with the mouth plug body and the upper edge of the mouth plug, and the tooth biting layer is sleeved outside the mouth plug center shaft; the locating rod, the mouth plug center shaft, the mouth plug body, and the bottom surface and the upper edge of the mouth plug are formed integrally; and the tooth biting layer is made of a thermoplastic material. According to the utility model, a relatively good location reference mark is added through a fixed teeth slot of the tooth biting layer, so that the accurate location is realized during reuse of the special mouth plug so as to overcome the defect of inaccurate location in the reuse of the special mouth plug, and to enhance the accuracy of the radiotherapy. Meanwhile, the biting repeatability and the durable stability of the special mouth plug are improved greatly, so that the special mouth plug serves as an ideal radiotherapeutic accessory for the radiotherapy.
Description
Technical field
This utility model belongs to field of medical devices, relates to a kind of radiotherapy dedicated port plug, is applied to oral cancer, and carcinoma of maxillary sinus is in the tumour radiotherapies such as carcinoma of tongue.
Background technology
At present; at oral cancer; carcinoma of maxillary sinus; in the carcinoma of tongue tumour radiotherapy; be the tissues such as protection tongue, hard palate, soft palate; tumor patient must be sucked (biting) wooden mouthful of plug; thereby reduce the radiological dose of tongue, hard palate, soft palate etc.; but the wooden mouthful of plug of present stage all is thermos bottle cork; patient generally needs 30 times repetitive therapy, is difficult to guarantee consistent when each bottle stopper is sucked the weight of (stinging with tooth), left and right directions position etc. and held the location, particularly after-stage; error strengthens, and directly affects the effect of radiation therapy.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to overcome prior art, and a kind of radiotherapy dedicated port plug of individuation is provided, by locating rod, and mouthful plug central shaft, individuation thermoplastic tooth is stung layer, mouthful cock body, mouthful plug bottom surface, mouth beyond the Great Wall edge forms; Locating rod is positioned at mouth beyond the Great Wall above the edge, mouth plug central shaft connector cock body and mouth be edge beyond the Great Wall, tooth is stung layer and is placed in outside mouthful plug central shaft, locating rod, mouthful plug central shaft, mouthful cock body, mouthful plug bottom surface, mouth beyond the Great Wall edge are formed in one, select indeformable when water temperature 100 is spent, do not dissolve, the preferably material of hardness is arranged, can select common wood, such as Lignum seu Ramulus Cunninghamiae Lanceolatae etc., also can select plastics.Tooth is stung layer material and is selected thermoplastic, in 60-70 degree water temperature, can melt deliquescing, after equitemperature reduces cooling, and again can hardening.
During use, this utility model in the water of 60-70 degree, was soaked 2-5 minute, color has original milky and becomes transparent color, from hard to soft simultaneously, take out this moment from water, allows patient bite tooth by tooth and sting layer, take out after cooling, this moment, tooth was stung a layer hardening, and stayed teeth mark.When reusing, patient can bite the same position that tooth is stung layer with tooth, thereby improves the degree of accuracy for the treatment of position.
Present stage, the incidence radiotherapy all needs the thermoplastic face shield to fix, when patient carries out the first fixing making of face shield, patient bites tooth and stings layer, and a mouthful plug bottom surface is arranged in the oral cavity, and locating rod is in the outside, oral cavity, the bar that is equivalent to a projection, it is the modelling of individuation that face shield is made, consistent with the profile of body surface, so also can form the projection that matches with this locating rod, be later each treatment, increased a preferably location positioning reference mark.
Usefulness of the present utility model is: radiotherapy mouth plug replaces with thermos cork now, there is not at present the dedicated port plug, patient approximately need to repeat to bite mouthful plug 30 times in treatment, because a mouthful plug does not have to fix with patients teeth to the alveolus that coincide, so in each treatment, the position that patient bites mouthful plug tends to occur skew up and down, radiotherapy dedicated port plug is for the mouth plug of in the past treating usefulness, increase the individuation tooth and stung layer, tooth is stung layer for thermoplastic material, in 60-70 degree water temperature, can melt deliquescing, after equitemperature reduces cooling, again can hardening.Sting layer when softening into transparence at tooth, patient directly bites tooth by tooth and stings layer, and approximately after 4 to 8 minutes, tooth is stung a layer cooling forming, forms the alveolus of individual patient.When patient carries out later on repetition tooth seaming plug, can accurately unanimously bite alveolus, displacement all around can not occur, increase the accuracy of radiotherapy, tooth is stung layer simultaneously preferably hardness, and larger than strengths of materials such as wood, stability will be got well.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is another structural representation of this utility model.
The specific embodiment
This utility model is further described in conjunction with the accompanying drawings and embodiments.
Referring to the radiotherapy dedicated port plug of Fig. 1, a kind of individuation, by locating rod 1, mouthful plug central shaft 2, tooth is stung layer 3, mouthful cock body 4, mouthful plug bottom surface 5, mouth beyond the Great Wall edge 6 forms; Locating rod 1 is positioned at mouth beyond the Great Wall above the edge 6, mouth plug central shaft 2 connector cock bodys 4 and mouth be edge 6 beyond the Great Wall, tooth is stung layer 3 and is placed in outside mouthful plug central shaft 2, locating rod 1, mouthful plug central shaft 2, mouthful cock body 4, mouthful plug bottom surface 5, mouth beyond the Great Wall edge 6 are formed in one, material therefor must be indeformable under water temperature 100 degree, do not dissolve, and preferably hardness is arranged.Generally select common wood such as Lignum seu Ramulus Cunninghamiae Lanceolatae etc., perhaps select plastics to replace.Tooth is stung layer 3 material selection thermoplastic, in 60-70 degree water temperature, can melt deliquescing, after equitemperature reduces cooling, and again can hardening.
Referring to Fig. 2, another structural representation of the present utility model is embodiment 1 to be made square, and structural member is all identical with embodiment 1.To adapt to the needs of different crowd.
The patient that need suck stopper by 20 routine carcinoma of tongues studies, divide into groups at random, every group of 10 people, pendulum position checking sheet by common mouthful of plug patient group and radiotherapy dedicated port plug patient group compares, data analysis, more common mouthful of plug of the pendulum bit error patient error that draws radiotherapy dedicated port plug patient group reduces obviously, and simultaneously radiotherapy dedicated port plug patient group rotates displacement hardly, repeatability and the durable stable stung at mouth have greatly improved, and are radiocurable desirable radiotherapy accessories.Compare for two groups and have statistically-significant difference (P＜0.005) sees Table 1.H(mm in the table) represent upper and lower displacement, V (mm) refers to left and right displacement, accelerator frame angle when angle is the machine checking.
