Technical Field
[0001] The invention relates to the technical field of mouth expanders, in particular to an oral mouth expander. Background Art
[0002] In oral medical and surgical care, it is often necessary to examine, treat or perform surgery on the patient's oral cavity. In order to better expose the lesions inside the oral cavity and facilitate the operation of medical staff, an oral expander is usually required.
[0003] However, there are some problems with the existing oral expansion devices, which bring many inconveniences to the work of medical staff. On the one hand, when expanding the lips, the existing expanders are difficult to flexibly adjust according to the size of the mouths of different patients, which makes it uncomfortable to use and may even cause damage to the lips. At the same time, in the process of expanding the lips, it cannot effectively prevent the patient from unconsciously closing the lips, affecting the operation; on the other hand, for situations where the upper and lower teeth need to be separated to avoid them from closing, the existing equipment often cannot meet the needs well. The existing oral expansion devices either lack effective means to separate the upper and lower teeth, or are unreasonably designed in the way to separate the upper and lower teeth. They cannot ensure the effective separation of the upper and lower teeth while adapting to the tooth spacing and bite strength of different patients, which can easily cause discomfort to patients and may also affect the accuracy and safety of oral operations.

[0007] Furthermore, the bidirectional telescopic rod comprises a telescopic cylinder fixedly connected to the arc-shaped plate, movable rods are movably inserted at both ends of the telescopic cylinder, and a spring is connected between the two movable rods.
[0008] Furthermore, the gear stopper is rotatably arranged at an end of the movable rod away from the spring.

[0011] Furthermore, one end of the bidirectional screw is fixedly connected to a rotating block.
[0012] Furthermore, the lip guard is made of polypropylene material.
[0013] Furthermore, the gear stopper is made of polyethylene material.
[0014] The beneficial effects of the present invention are:
[0015] The present invention adjusts the distance between the two connecting plates through a bidirectional screw, thereby adjusting the spacing between the two lip stops, and can be flexibly adjusted according to the oral size of different patients, thereby improving the comfort of patients and avoiding damage to the lips. The bidirectional telescopic rod is used to connect the tooth stops, which can effectively separate the upper and lower teeth and adapt to the tooth spacing and bite strength of different patients.

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.
[0021] like Figure 1 and Figure 2As shown, an oral expander comprises a base 1, both ends of the base 1 are fixedly connected with mounting plates 2, a bidirectional screw 3 is rotatably connected between the two mounting plates 2, both ends of the bidirectional screw 3 are threadedly connected with connecting plates 4, the top of the connecting plate 4 is fixedly connected with a lip stopper 5, the two lip stops 5 are symmetrically arranged, one side of the lip stopper 5 is fixedly connected with an arc plate 6, one end of the arc plate 6 away from the lip stopper 5 is fixedly connected with a bidirectional telescopic rod 7, the bidirectional telescopic rod 7 is vertically arranged, and the upper and lower ends of the bidirectional telescopic rod 7 are connected with gear stops 8.
[0022] The bidirectional telescopic rod 7 includes a telescopic cylinder 71 fixedly connected to the arc plate 6, and movable rods 72 are movably inserted at both ends of the telescopic cylinder 71, and a spring is connected between the two movable rods 72; the setting of the spring makes the bidirectional telescopic rod 7 have a certain elastic buffering effect during use, which can not only adapt to different tooth spacing and bite strength, but also reduce the hard impact on the teeth, further improving the comfort of the patient. .
[0023] The gear stopper 8 is rotatably arranged at one end of the movable rod 72 away from the spring; the rotational arrangement enables the gear stopper 8 to be adjusted according to different angles of the patient's teeth, so as to better fit the teeth and improve the expansion effect.
[0024] The front and rear ends of the top of the tooth stopper 8 are fixedly connected to a limiting plate 9; the limiting plate 9 can prevent the teeth from excessively moving and separating from the tooth stopper 8, ensuring that the teeth are separated in the correct position and improving the stability of oral operation.
[0025] A slide groove 101 is provided on the upper surface of the base 1 , and a slider 10 is fixedly connected to the top of the connecting plate 4 , and the slider 10 is slidably connected to the slide groove 101 , so that the connecting plate 4 is more stable during movement.
[0026] One end of the bidirectional screw 3 is fixedly connected to a rotating block 11 .
[0027] The lip guard 5 is made of polypropylene material; polypropylene material has good flexibility and biocompatibility, has little irritation to the lips, and improves the comfort of the patient.
[0028] The tooth stopper 8 is made of polyethylene material; the polyethylene material has a certain hardness and toughness, and can effectively separate the teeth while causing little damage to the teeth.
[0029] Working principle:
[0030] The oral expander adjusts the distance between the two lip stops 5 through the bidirectional screw 3 on the base 1 to adapt to the oral sizes of different patients. The lip stops 5 on both sides open the patient's lips to both sides, and the arc plate 6 extends deep into the teeth on both sides along the inner side of the mouth. The upper and lower teeth on both sides bite on the tooth stops 8 respectively, and the upper and lower teeth are separated by the bidirectional telescopic rod 7, which can effectively separate the upper and lower teeth and adapt to the tooth distance and bite strength of different patients.
[0031] The present invention can be flexibly adjusted according to the oral size and tooth spacing of different patients, thereby improving the applicability of the mouth expander, effectively preventing the patient from unconsciously closing their lips and teeth, and ensuring the smooth progress of oral operations. The designs of the various components cooperate with each other, thereby improving the stability of the mouth expander and the accuracy of operation, and providing a reliable tool for oral medical and surgical care.
[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
