Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a tongue blocking device for oral restoration and orthodontics. Background Art

[0002] Oral restoration, commonly known as dental prosthesis, is mainly aimed at the treatment of tooth defects and missing teeth, such as inlays, full crowns, dentures, etc. It also includes the use of artificial restorations to treat periodontal disease, temporomandibular joint disease and maxillofacial tissue defects, such as bite plates, periodontal splints, prostheses, etc.

[0003] During oral restoration, due to the lack of a tongue stopper, the tongue itself can easily interfere with the operation, and the patient can easily move the tongue involuntarily, which can easily interfere with the surgical operation, and the tongue can also be easily injured by surgical instruments. During the bonding process of the restoration, saliva is often secreted in the mouth. A large amount of saliva can easily cause discomfort to the patient, interfere with the surgical operation, affect the field of vision, and cause the operation time to be prolonged and the bonding effect to be reduced. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides the following technical solutions:

[0005] A tongue stopper for oral rehabilitation and orthodontics comprises a U-shaped saliva suction device, wherein a tongue stopper is fixedly mounted at the U-shaped notch of the saliva suction device; an opener is fixedly mounted on the saliva suction device, wherein the opener comprises an upper support plate, a lower support plate, an opening mechanism and a screw rod, wherein the lower support plate is fixedly mounted on the saliva suction device, wherein the upper support plate and the lower support plate are detachably connected via the opening mechanism, wherein the screw rod is rotatably mounted in the lower support plate, wherein the opening mechanism is driven to move by rotating the screw rod, thereby controlling the spacing between the upper support plate and the lower support plate.

[0006] Furthermore, the expansion mechanism includes a front support rod and a rear support rod, the front support rod is located in front of the rear support rod, both ends of the front support rod and the rear support rod are rotatably connected to the upper support plate and the lower support plate respectively, the front support rod, the rear support rod, the upper support plate and the lower support plate surround a quadrilateral structure, and the upper support plate is controlled to move away from the lower support plate by rotating the front support rod and the rear support rod, while the front end of the upper support plate is controlled to tilt upward.

[0007] Furthermore, an installation groove is provided on the lower support plate, the screw rod is rotatably installed in the installation groove, a sliding block is slidably arranged in the installation groove, and the sliding block is threadedly sleeved on the screw rod; the lower ends of the front support rod and the rear support rod are rotatably installed in the installation groove, and the sliding block is driven by rotating the screw rod to slide against the rear support rod, thereby preventing the rear support rod from rotating.

[0008] Furthermore, the length of the front support rod is greater than the length of the rear support rod.

[0009] Furthermore, the upper support plate and the lower support plate are both arc-shaped structures that fit the anatomical structure of the human body.

[0010] Furthermore, the lower inner side of the saliva ejector gradually tilts outwards, the saliva ejector is a hollow structure, and a plurality of saliva suction holes are provided below the saliva ejector to communicate with the interior of the saliva ejector; a straw is fixedly provided on the lower support plate, and the straw is communicated with the interior of the saliva ejector.

[0011] Furthermore, the bottom of the tongue guard is a curved groove structure that fits the anatomical structure of the human body, and a plurality of small holes are provided on the tongue guard.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The saliva suction device of the present invention is a U-shaped structure, and the saliva suction device can be placed between the outer periphery of the tongue and the teeth, and the inner lower side of the saliva suction device gradually tilts toward the teeth, so that the saliva suction device can be better inserted between the outer periphery of the tongue and the teeth, and a plurality of saliva suction holes are provided at the bottom of the saliva suction device, which can improve the effect and speed of absorbing saliva;

[0014] 2. The tongue guard of the present invention has an arc groove structure that fits the tongue under it, which can better fit the tongue, and the tongue guard is installed at the U-shaped notch of the saliva suction device. The tongue guard and the saliva suction device are combined into one, and the volume of the tongue guard and the saliva suction device is reduced as much as possible, so as to avoid interference between the tongue guard and the saliva suction device in operation, which is convenient to use. A number of small holes are provided on the tongue guard to prevent negative pressure from being formed between the bottom of the tongue guard and the tongue, so as to prevent the tongue guard from adsorbing the tongue;

[0015] 3. The mouth opener of the present invention comprises an upper support plate, a lower support plate, a front support rod, a rear support rod and a screw rod. The lower support plate is fixedly mounted on the saliva suction device, and the upper support plate and the lower support plate are detachably connected through the front support rod and the rear support rod. The screw rod is rotated to drive the sliding block on the lower support plate to slide against the rear support rod, which supports the rotation of the rear support rod and drives the front support rod to rotate. While controlling the upper support plate to move away from the lower support plate, the front end of the upper support plate is controlled to tilt upward, thereby supporting the teeth after the mouth is opened, and supporting the upper teeth and the lower teeth respectively through the upper support plate and the lower support plate, thereby reducing the volume of the mouth opener as much as possible, which is beneficial to surgical operations. The present invention cleverly combines the saliva suction device, the mouth opener and the tongue stopper to reduce the volume of the device as much as possible without reducing the functions of the three devices, making it easy to use and operating while ensuring space for surgical operations.
