Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an oral opening degree trainer. Background Art

[0002] Mouth opening is an important foundation for oral function, and the degree of mouth opening significantly impacts a patient's chewing, speech, swallowing, social interaction, and other functions. Difficulty opening the mouth is common in patients with maxillofacial fractures, oral cancer surgery, temporomandibular joint dysfunction, orthognathic surgery, and other conditions.

[0003] Mouth opening training should be tailored to the patient's mouth opening condition, requiring appropriate training equipment for both trismus and normal mouth opening. Existing mouth opening training tools cannot adjust the mouth opening size in subtle and gradual steps, making them unsuitable for gradual mouth opening training. Utility Model Content

[0004] The technical problem to be solved by the utility model is to develop an oral opening degree trainer which can finely and gradually adjust the mouth opening size of an occlusal piece.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] An oral opening degree trainer comprises two bite plates, two first support rods, two second support rods and an adjustment module. The adjustment module comprises a sleeve and a latch. The inner sides of the head ends and the tail ends of the two bite plates are hinged to one end of the first support rod and one end of the second support rod respectively. The other ends of the two first support rods are fixedly connected to the front side wall of the sleeve. The other ends of the two second support rods are inserted into the sliding holes of the rear side wall of the sleeve so that the head ends of the two bite plates are moved inward. A latch adapted to the inner diameter of the sleeve is movably arranged in the sleeve, and a nose cone is provided on the head of the latch.

[0007] The beneficial effects of the present invention are as follows: when the mouth opening of the bite plate cannot meet the patient's need for further opening of the mouth, the pin is pushed toward the inside of the sleeve, and under the action of the nose cone, the second support rod is gradually pushed out of the sliding hole, and the tail end of the bite plate expands outward, thereby making the mouth opening of the tail end of the bite plate larger; the pin, sleeve and second support rod with the nose cone are provided, so that the mouth opening degree of the tail end of the bite plate can be finely and gradually adjusted, thereby meeting the patient's need for gradual mouth opening training.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a limiting ring is provided on the rod head of the second support rod in the sleeve, and the outer diameter of the limiting ring is larger than the inner diameter of the sliding hole.

[0010] Furthermore, the tail of the latch is threadedly connected to the inner wall of the sleeve, and a handle is provided on the end surface of the tail of the latch.

[0011] Furthermore, a plurality of steps are arranged at intervals on the occlusal surface of the occlusal piece.

[0012] Furthermore, the bite piece is made of food-grade silicone. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 4 As shown, embodiment 1 of the present invention is an oral opening degree trainer, comprising two bite plates 1, two first support rods 2, two second support rods 3 and an adjustment module 4, the adjustment module 4 comprising a sleeve 41 and a latch 42, the inner sides of the head ends and the tail ends of the two bite plates 1 are hinged to one end of the first support rod 2 and one end of the second support rod 3 respectively, the other ends of the two first support rods 2 are fixedly connected to the front side wall of the sleeve 41, and the other ends of the two second support rods 3 are inserted into the sliding holes 411 of the rear side wall of the sleeve 41 so that the head ends of the two bite plates 1 are brought closer to the inside, a latch 42 adapted to the inner diameter of the sleeve 41 is movably provided in the sleeve 41, and a nose cone 421 is provided at the head of the latch 42.

[0021] When the mouth opening of the bite plate 1 cannot meet the patient's need for further mouth opening, the pin 42 is pushed toward the inside of the sleeve 41, and under the action of the nose cone 421, the second support rod 3 is gradually pushed out of the sliding hole 411, and the tail end of the bite plate 1 expands outward, thereby making the mouth opening at the tail end of the bite plate 1 larger; the pin 42 with the nose cone 421, the sleeve 41 and the second support rod 3 are provided, so that the mouth opening degree of the tail end of the bite plate 1 can be finely and gradually adjusted, thereby meeting the patient's need for gradual mouth opening training.

[0022] Example 2 of the present invention is an oral opening degree training device. Based on Example 1, a limit ring 31 is provided on the rod head of the second support rod 3 within the sleeve 41. The outer diameter of the limit ring 31 is larger than the inner diameter of the slide hole 411. The limit ring 31 can prevent the second support rod 3 from overtravel and sliding out of the slide hole 411.

[0023] Embodiment 3 of the present invention is an oral opening training device. Based on Embodiment 1, the rear end of a latch 42 is threadedly connected to the inner wall of a sleeve 41, and a handle 422 is provided on the end surface of the rear end of the latch 42. The threaded connection structure is stable, and the length of the latch 42 inserted into the sleeve 41 can be finely and gradually adjusted, thereby finely and gradually adjusting the contact position between the nose cone 421 and the second support rod 3, thereby finely and gradually adjusting the opening of the rear end of the bite plate 1; rotating the latch 42 using the handle 422 saves effort.

[0024] Embodiment 4 of the present invention is an oral opening degree training device. Based on embodiment 1, a plurality of steps 11 are provided at intervals on the occlusal surface of the occlusal plate 1. The steps 11 can facilitate the patient's tooth occlusion and also assist the patient in gradually performing mouth opening degree training.

[0025] Embodiment 5 of the present invention is an oral opening training device, based on any one of embodiments 1 to 4, wherein the bite plate 1 is made of food-grade silicone. Food-grade silicone is safe to use and is conducive to long-term bite of patients.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
