DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1-9 In one embodiment of the present invention, an oral septum tongue lighting device has a relative first direction x, a second direction y, and a third direction z. The oral septum tongue lighting device includes a mandibular frame assembly 1, the mandibular frame assembly 1 including a mandibular frame 101, a lower curved wall 102, a side groove 103, an elastic member 104, and a guide groove 105. The lower curved wall 102 is fixedly embedded in the upper surface of the mandibular frame 101 along the third direction z. The side grooves 103 are arranged on both sides of the mandibular frame 101 along the first direction x. The elastic member 104 is assembled in the side groove 103. A guide groove 105 is further provided at one end of the side groove 103. The mandibular frame assembly 1 has relative mandibular first surface a1, mandibular second surface a2, mandibular third surface a3, and mandibular fourth surface a4. The mandibular first surface a1 is arranged on the upper surface of the mandibular frame 101, the mandibular second surface a2 is arranged on the inner wall surface of the lower curved wall 102, the mandibular third surface a3 is arranged on the outer curved surface of the mandibular frame 101, and the mandibular fourth surface a4 is arranged on the lower surface of the mandibular frame 101; the side arm assembly 2, the side arm assembly 2 includes a side arm 201 and a side shaft 204, one end of the side arm 201 is fixedly connected to the side shaft 204, the side shaft 204 is rotatably inserted into the side groove 103, and the side arm 201 is movably abutted against the elastic member 104; the maxillary frame assembly 3, the maxillary frame assembly 3 includes a maxillary frame 301 and a maxillary arm 302, both ends of the maxillary frame 301 are fixedly connected to the maxillary arm 302, and the maxillary arm 302 is respectively assembled and connected with the two groups of side arms 201.

[0030] In actual application of this embodiment, when the device is used for oral treatment, the mandibular frame 101 has a mandibular first surface a1, a mandibular third surface a3 and a mandibular fourth surface a4. The mandibular first surface a1 is used to support the sublingual fold in the oral cavity, so that the sublingual fold passes through the mandibular frame 101 and the maxillary frame 301 and is placed horizontally on the mandibular first surface a1. The mandibular second surface a2 is used to abut the tip of the tongue, so that a barrier is formed between the tongue and the teeth, which can prevent the equipment from scratching or pricking the lower teeth during treatment. The tongue can be stimulated, and at the same time, broken teeth or dirt can be prevented from flowing back to the bottom of the tongue when the affected area is rinsed, causing discomfort to the patient. The mandibular third surface a3 is used to abut the lower gingival wall, so that a gap is left between the lower curved wall 102 and the lower tooth area. On the one hand, it avoids interference between the equipment and the lower curved wall 102 when the operator treats the lower tooth area. On the other hand, the mandibular lamp group 113 assembled on one side of the mandibular frame 101 can continuously illuminate the upper and lower tooth areas. The mandibular fourth surface a4 is set toward the sublingual gland side. , so that the fourth surface a4 of the mandible is fitted to the end of the mandible. At the same time, the maxillary frame 301 is fitted to the end of the maxillary frame, and the maxillary arms 302 at both ends of the maxillary frame 301 are movably connected to the mandibular frame 101 through the side arms 201. The side arms 201 are rotatably assembled on the mandibular frame 101 and elastically connected to the side grooves 103. When the device is in the patient's mouth, the elastic support of the elastic member 104 can support the patient's upper and lower jaws, thereby preventing the patient from being unable to open the mouth for a long time due to facial muscle soreness. The oral cavity is closed autonomously to prevent affecting the treatment process. At the same time, the lighting lamps arranged along the layout direction of the mandibular frame 101 and the maxillary frame 301 can form upper and lower ring-shaped lighting areas inside the oral cavity, and the lighting lamps in the lower tooth area point to the upper tooth part, and the lighting lamps in the upper tooth area point to the lower tooth part, so that when the treatment equipment moves in the oral cavity, it will not affect the overall lighting brightness when blocking the local light source. In addition, since the lighting lamps are arranged in a ring shape, the projection effect of the equipment under the light source is weakened, thereby improving the lighting effect.

[0031] See also Figure 2 and Figure 6 In a preferred embodiment of the present invention, the mandibular frame assembly 1 further includes a curved groove 106, a bottom groove 107 and a sewage suction hole 108, the curved groove 106 is arranged at the end of the mandibular frame 101 along the second direction y, the bottom groove 107 is arranged on the lower surface of the mandibular frame 101, and a plurality of sewage suction holes 108 are provided on the bottom groove 107, and the sewage suction holes 108 are arranged along the layout direction of the lower curved wall 102.

[0032] In actual application of this embodiment, the curved groove 106 is arranged on one side of the frenulum of the tongue, and its groove-shaped curved wall avoids scratching the frenulum of the tongue to prevent discomfort to the patient. The bottom groove 107 is arranged on the lower surface of the mandibular frame 101 and is arranged toward the side of the sublingual gland so that the bottom groove 107 fits one end of the sublingual gland. The several suction holes 108 provided on the bottom groove 107 can be used to pump saliva secreted in the oral cavity and clean the dirty liquid left by the affected part. Several of the suction holes 108 are arranged along the layout direction of the lower curved wall 102, so that the several suction holes 108 can respectively suck the dirty liquid at various positions in the mandible.

[0033] See also Figure 8 In a preferred embodiment of the present invention, the mandibular frame assembly 1 further includes a main pipe 109, a pump suction pipe 110 and a shunt pipe 111. The main pipe 109 is arranged inside the mandibular frame 101, and one end of the main pipe 109 is connected to the pump suction pipe 110, and the other end of the main pipe 109 is connected to the shunt pipe 111. The shunt pipe 111 is arranged in the mandibular frame 101 along the layout direction of the lower curved wall 102, and the shunt pipe 111 is connected to several of the sewage suction holes 108.

[0034] In actual application of this embodiment, the main pipe 109 is independently arranged in the mandibular frame 101 and one end of the main pipe 109 is connected to the pump suction pipe 110. The other end of the main pipe 109 is connected to the shunt pipe 111. The shunt pipe 111 is arranged along the layout direction of the lower curved wall 102 and is connected to the multiple sewage suction holes 108. When the pump suction pipe 110 is pumping, various positions in the oral cavity can be sucked simultaneously through the multiple sewage suction holes 108 to avoid the accumulation of sewage in a certain position and causing discomfort to the patient.

[0035] In one case of this embodiment, the end of the pump suction tube 110 is connected to a negative pressure suction pump, and in the treatment working state, the negative pressure at one end of the pump suction tube 110 is in a constant state. According to the Bernoulli principle, when the flow rate is constant, the smaller the orifice diameter at one end of the sewage suction hole 108 is, the greater the flow rate in the diversion tube 111 is. Therefore, the flow rate in the tube can be controlled by adjusting the negative pressure.

[0036] See also Figure 8 In a preferred embodiment of the present embodiment, the mandibular frame assembly 1 also includes an electric control line 112 and a mandibular light group 113, and several of the mandibular light groups 113 are arranged along the layout direction of the third surface a3 of the mandibular, and several of the mandibular light groups 113 are arranged close to one side of the shunt tube 111, and the electric control line 112 is electrically connected to the several mandibular light groups 113.

[0037] In actual application of this embodiment, the electric control line 112 is used to control the opening and closing of the circuits in the mandibular lamp group 113 and the upper electric control line 303, and the shunt tube 111 is arranged close to one side of the mandibular lamp group 113, so that when the mandibular lamp group 113 generates heat after working for a long time, the dirty liquid pumped in the shunt tube 111 can have a liquid cooling effect, and heat exchange is achieved through the flowing liquid, thereby reducing heat accumulation in the lighting lamp and achieving the purpose of cooling and heat dissipation.

[0038] In one case of this embodiment, since the dirty fluid in the oral cavity mainly accumulates on the mandibular side, the shunt tube 111 is only provided in the mandibular frame 101 .

[0039] See also Figure 4 and Figure 5 In a preferred embodiment of the present invention, the maxillary frame assembly 3 further includes an upper electric control line 303, an upper light trough 304 and a maxillary light group 305. The upper electric control line 303 is arranged inside the maxillary frame 301 along the layout direction of the maxillary frame 301. The maxillary frame 301 has a relative maxillary first surface b1, a maxillary second surface b2 and a maxillary third surface b3. The maxillary first surface b1 is arranged on the upper surface of the maxillary frame 301 along the third direction z. The maxillary second surface b2 is arranged on the outer curved surface of the maxillary frame 301, the maxillary third surface b3 is arranged on the lower surface of the mandibular frame 101, the maxillary first surface b1 is used to abut the upper jaw in the oral cavity, and the maxillary second surface b2 is used to abut the upper gingival wall. The upper lamp groove 304 is arranged on the maxillary third surface b3 along the layout direction of the maxillary frame 301, and several of the maxillary lamp groups 305 are assembled in the upper lamp groove 304 and are electrically connected to the upper electric control line 303.

[0040] In actual application of this embodiment, the upper electric control wire 303 is passed through the maxillary frame 301 and is electrically connected to several maxillary lamp groups 305 in the upper lamp groove 304. At the same time, the end of the upper electric control wire 303 is electrically connected to the electric control wire 112 to control the opening and closing of the mandibular lamp group 113 and the maxillary lamp group 305.

[0041] In one case of this embodiment, the maxillary frame assembly 3 also includes an adjustment wire 306, which is arranged between the side arm 201 and the maxillary arm 302, and is used to adjust the rotation angle between the side arm 201 and the maxillary arm 302, and its opening and closing angle can be adjusted according to the size of the mouth of different patients.

[0042] See also Figure 3 and Figure 6In a preferred embodiment of the present invention, the side arm assembly 2 also includes a side rod 202 and a pin head 203, one end of the side rod 202 is fixedly connected to the side arm 201, and the other end of the side rod 202 is fixedly connected to the pin head 203, and the pin head 203 is limitedly slidably assembled in the guide groove 105, and the oral tongue-septum lighting device also includes a valve plate assembly 4, the valve plate assembly 4 includes a valve plate 401, a pulling arm 402 and a baffle 403, the valve plate 401 is slidably set on the first surface a1 of the maxilla, one end of the pulling arm 402 is movably connected to the valve plate 401, and the other end of the pulling arm 402 is movably connected to the pin head 203, and a plurality of baffles 403 are also provided on one side of the valve plate 401, and the baffles 403 are matched with a plurality of sewage suction holes 108.

[0043] In actual application of this embodiment, when a large amount of waste liquid gathers in the patient's oral cavity during treatment, the human body's instinctive swallowing action will cause the upper and lower jaws to bite together. When the patient's upper and lower jaws move closer, the maxillary frame 301 pulls the side arm 201 to move synchronously during the movement, and causes the side arm 201 to rotate along its fixed axis. One end of the side arm 201 abuts against the elastic member 104 during the movement, and the side rod 202 and the pin head 203 at the other end of the side arm 201 pull the pulling arm 402 during the rotation, thereby pushing the valve disc 401 to move. When the valve disc 401 slides on the first surface a1 of the mandible, several baffles 403 at one end thereof slide synchronously on one side of the waste liquid suction hole 108, thereby controlling the size of the orifice of one end of the waste liquid suction hole 108, so that when the patient feels uncomfortable due to a large amount of waste liquid gathering in the cavity, the flow rate of the pump can be independently controlled to speed up the suction of the waste liquid to reduce the discomfort.

[0044] The above embodiment of the present invention provides an oral tongue-septum lighting device, in which a maxillary frame 301 is movably mounted on the top of the mandibular frame 101, which can provide auxiliary support for the patient's upper and lower jaws during treatment, thereby reducing the soreness of the patient's facial muscles. At the same time, the patient's biting action can be used to independently control the flow rate of the pump suction, making it convenient for the patient to freely adjust the intensity of the pump suction, eliminating the step of manually sucking out dirty liquid by the therapist, and the flow of liquid can also be used to dissipate heat from the lighting lamp to prevent the lamp source from overheating and causing discomfort to the patient.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
