[0030] In the process of oral medical examination and treatment, mouth openers are an important medical device. Existing mouth openers mainly consist of two support arms, which can help patients keep their mouths open so that doctors can conduct examinations and treatments. However, in clinical applications, it has been found that simply keeping the mouth open often cannot meet the needs of a complete oral examination, especially when a tongue examination is required.
[0031] Currently available oral mouth openers lack tongue depressor functionality, requiring doctors to operate the mouth opener with one hand and use a separate tongue depressor with the other. This not only increases the doctor's workload but also easily causes interference between the instruments. Furthermore, using a separate tongue depressor also presents problems such as unstable fixation and easy slippage, affecting the accuracy and efficiency of the examination.
[0032] Reference Figures 1 to 4 This application provides an oral mouth opener capable of mounting a tongue depressor, including an mouth opener body 100, a tongue depressor mounting base 200, and a tongue depressor 300.
[0033] The tongue depressor mounting base 200 includes a connecting base 210 and a fixing steel plate 220. The connecting base 210 is fixed on the connecting shaft 110 of the mouth opener body 100. One end of the fixing steel plate 220 is fixed on the connecting base 210, and the other end of the fixing steel plate 220 extends to the opening end 120 of the mouth opener body 100. A slot 221 is formed on the lower surface of the fixing steel plate 220. The slot 221 extends along the extending direction of the fixing steel plate 220. The slot 221 forms a groove at the end of the fixing steel plate 220. The tail of the tongue depressor 300 is used to insert into the slot 221.
[0034] The front part of the tongue depressor 300 is manually bent, and then the tail part of the tongue depressor 300 is inserted into the slot 221 of the fixing steel plate 220 for fixation. During use, the doctor holds the mouth opener body 100 and supports the opening and closing ends 120 of the mouth opener between the upper and lower teeth to open the mouth. The bent tongue depressor 300 is inserted into the mouth to press down the tongue. In this way, the mouth opener can simultaneously open the mouth and press down the tongue. The doctor does not need to operate the mouth opener body 100 with one hand and use the independent tongue depressor 300 with the other hand, which effectively reduces the doctor's workload. In addition, the tongue depressor 300 of this application is more stable after being fixed compared with manual fixation.
[0035] In order to secure the tongue depressor 300 installed in the slot 221, in some embodiments, a positioning device 400 is provided on the fixing steel plate 220, which is used to fix the tongue depressor 300 inserted into the slot 221.
[0036] In some embodiments, the positioning device 400 includes a mounting base 410, a clamping plate 420, and an elastic member 430. The mounting base 410 is fixed to the back of the fixing steel plate 220, and the clamping plate 420 is hinged to the mounting base 410. The clamping plate 420 can rotate about the hinge point. A through hole 221 with a connecting slot 221 is provided on the fixing steel plate 220. One end of the clamping plate 420 extends into the through hole 221. The elastic member 430 is fixed to the fixing steel plate 220 and connected to the other end of the clamping plate 420. A plurality of slots 310 are provided on the surface of the tail of the tongue plate 300. Each slot 310 is arranged at intervals along the length direction of the tongue plate 300. One end of the clamping plate 420 extending into the through hole 221 can be embedded in the slot 310.
[0037] During use, press the end of the clamping plate 420 away from the through hole 221, causing the clamping plate 420 to compress the elastic member 430. The end of the clamping plate 420 that extends into the through hole 221 is lifted out of the through hole 221. After the tail of the bent tongue depressor 300 is inserted into the slot 221, release the clamping plate 420. Under the action of the elastic member 430's rebound force, the end of the clamping plate 420 extends into the through hole 221 and is embedded in the slot 310 of the tongue depressor 300, thereby fixing the tongue depressor 300 in the slot 221 and preventing the tongue depressor 300 from sliding in the slot 221 during use.
[0038] Furthermore, when it is necessary to adjust the length of the tongue depressor 300, the tongue depressor 300 is slid along the length direction of the slot 221. After the tongue depressor 300 has slid into place, the retaining plate 420 is then inserted back into the through hole 221 to hold the tongue depressor 300 in place. Therefore, this application can also achieve the adjustment of the length of the tongue depressor 300.
[0039] In some embodiments, the elastic member 430 is a columnar spring.
[0040] Of course, the elastic component 430 can also be configured as a disc spring or other structure.
[0041] In some other embodiments, the positioning device 400 can also be configured as a bolt structure. Specifically, a threaded hole is opened on the side of the fixing steel plate 220, and a bolt is installed in the threaded hole. One end of the bolt extends into the slot 221, and the other end of the bolt is located outside the slot 221. After the tail of the tongue plate 300 is inserted into the slot 221, the bolt is rotated so that the end of the bolt located inside the slot 221 presses against the tongue plate 300, thereby achieving the positioning of the tongue plate 300.
[0042] To ensure a more secure engagement between the end of the card plate 420 extending into the through hole 221 and the slot 310 on the tongue depressor 300, in some embodiments, the end of the card plate 420 extending into the through hole 221 is provided with a wedge-shaped end, the width of which is smaller than the width of the slot 310. The wedge-shaped end of the card plate 420 can be directly embedded into the slot 310.
[0043] To facilitate pressing, in some embodiments, a pressing plate 421 is provided at the end of the card plate 420 away from the through hole 221.
[0044] In some embodiments, the surface of the pressing plate 421 is provided with stripes. This can increase the friction of the surface of the pressing plate 421.
[0045] In some embodiments, the fixing steel plate 220 is an inwardly curved arc structure. Since the initial state of the tongue depressor 300 is a straight plate structure, during use, the doctor will manually bend the front of the tongue depressor 300, while the tail of the tongue depressor 300 remains a straight plate structure. In this way, when the tail of the straight tongue depressor 300 is inserted into the arc-shaped slot 221, the tongue depressor 300 and the slot 221 can fit more tightly, further improving the stability of the tongue depressor 300.
[0046] In some embodiments, the tongue depressor mounting base 200 is detachably connected to the connecting shaft 110 of the mouth mouth device body 100. When the tongue depressor 300 is installed on the mouth mouth device body 100 during surgery, the tongue depressor mounting base 200 is installed on the connecting shaft 110 of the mouth mouth device body 100. When the tongue depressor 300 is no longer needed, the tongue depressor mounting base 200 can be removed.
[0047] In some embodiments, a polygonal post 111 is provided on the connecting shaft 110 of the opening body 100, and a polygonal hole is provided on the connecting seat 210, with the polygonal hole and the polygonal post 111 cooperating with each other.
[0048] Specifically, in this application, the polygonal column 111 is a hexagonal prism, which is vertically fixed on the connecting shaft 110. The polygonal hole on the connecting seat 210 is a hexagonal hole, which is opened in the lower center of the connecting seat 210. When it is necessary to install the tongue depressor 300, the tongue depressor mounting seat 200 can be installed on the polygonal column 111.
[0049] It should be noted that since the fixing steel plate 220 is an inwardly curved arc structure, the connecting seat 210 will not detach from the polygonal column 111 during the tongue depressor 300 insertion process. Only when medical personnel grasp both sides of the connecting seat 210 and pull it outward will the connecting seat 210 detach from the polygonal column 111.
[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
