Description

Technical Field

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

[0002] When filling a tooth, a protective coating needs to be applied to the filled tooth. However, some people have particularly thick cheek muscles, and the inner cheek is difficult to separate from the tooth after being fitted. As a result, the cheek mucosa is easily abraded when filling, repairing or adjusting the tooth. If the cheek mucosa is accidentally abraded, it will not only cause pain and discomfort to the patient, but may also cause mucosal damage and even lead to serious consequences such as infection.

[0005] Cheek pushers are arranged on both sides of the palate pressing head. The cheek pushers include an insertion rod with adjustable length, and a pushing head is fixed to the end of the insertion rod.

[0006] Preferably, slots are provided on both sides of the palatal pressure head, the support rod is movably inserted into the slots, a thread is provided on the top rod body of the support rod, and a support nut is movably screwed on the top of the support rod.

[0007] Preferably, the cheek pusher also includes a socket rod, the plug rod is movably plugged into the socket rod, a fixing plate is fixed inside the socket rod, and a spring is fixed between the fixing plate and the plug rod.

[0008] Preferably, a sliding groove is provided on the outer side of the socket rod, a connecting rod is fixed on the side of the plug rod, the connecting rod is adapted to the sliding groove, and a push plate is fixed on the end of the connecting rod.

[0009] Preferably, the top of the palate pressure head is formed with an arc-shaped fitting surface.

[0010] Preferably, an elastic pad is fixed to the bottom end of the support rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The oral opener is provided with a palate pressure head, a cheek pusher and a support rod. After installation, the palate pressure head presses against the upper palate to open the patient's mouth, and the push plate is released. Under the elastic force of the spring, the insertion rod moves to both sides, and the pusher head pushes the cheek to form a certain distance between the inner side of the cheek and the outer side of the tooth, thereby achieving the separation of the inner side of the cheek from the teeth, making it convenient for doctors to fill, repair or reconcile the teeth, improving the safety of the operation and increasing the comfort of the patient.

[0013] At the same time, a triangular structure is formed between the gum pressure plate, the shaping rod and the support rod in the opener, so that the opener can be stably supported, effectively preventing the opener from falling off from the oral cavity, and further improving the practicability of the device.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 3As shown, the utility model provides a technical solution: an oral opener, including a palatal pressure head 1, extension plates are formed on both sides of the palatal pressure head 1, and arc-shaped fitting surfaces 101 are formed on the top of the extension plates and the palatal pressure head 1, and the arc-shaped fitting surfaces 101 fit with the arc surface of the upper palate, thereby stably supporting the upper palate, and two symmetrically arranged support rods 2 are arranged at the bottom end of the palatal pressure head 1. In order to prevent the support rods 2 from causing damage to the buccal fat pads on both sides of the tongue, elastic pads 201 are fixed to the bottom ends of the support rods 2, and a rotating rod 501 is movably connected to the side of the support rod 2, and a shaping rod 502 is connected to the rod body of the rotating rod 501. In this solution, the shaping rod 502 is a soft plastic alloy universal tube that is easy to shape at will, and a gum pressure plate 503 is connected between the two shaping rods 502. The outer side of the gum pressure plate 503 is formed with a certain curvature, which can fit with the inner side of the gums of the lower jaw.

[0020] Cheek pushers 4 are provided on both sides of the palate pressing head 1, wherein Figure 3 As shown, the cheek pusher 4 includes an insertion rod 403 with adjustable length, and a pushing head 407 made of rubber material is fixed to the end of the insertion rod 403.

[0021] To facilitate the insertion of the opener into the mouth, slots 102 are provided on both sides of the palate pressure head 1, the support rod 2 is movably inserted into the slots 102, a thread is provided on the top rod body of the support rod 2, and a support nut 3 is movably screwed on the top of the support rod 2, and the support nut 3 is located below the palate pressure head 1.

[0022] Similarly, to facilitate the insertion of the mouth opener into the mouth, Figure 3 As shown, the cheek pusher 4 also includes a socket rod 401, and the plug rod 403 is movably connected to the socket rod 401. A fixed plate 402 is fixed in the socket rod 401, and a spring 404 is fixed between the fixed plate 402 and the plug rod 403. In a specific embodiment of the present scheme, a sliding groove is also opened on the outer side of the socket rod 401, and a connecting rod 405 is fixed on the side of the plug rod 403. The connecting rod 405 is adapted to the sliding groove. In order to facilitate the scaling of the plug rod 403, a push plate 406 is fixed at the end of the connecting rod 405.

[0023] To supplement this solution, when installing the opener, first press the push plate 406 with the thumb and index finger to retract the two insertion rods 403 into the socket rod 401, place the two support rods 2 on the cheek fat pads on both sides of the tongue, and lift the palate pressure head 1 with the other hand until the palate pressure head 1 is pressed against the upper palate, and then rotate the support nut 3 until the top surface of the support nut 3 contacts the bottom surface of the palate pressure head 1. At this time, the position of the palate pressure head 1 is adjusted, and then the push plate 406 is released. Under the elastic force of the spring 404, the insertion rod 403 moves to both sides, and the push head 407 pushes the cheek to form a certain distance between the inner side of the cheek and the outer side of the tooth. Finally, the shape of the shaping rod 502 is changed to make the gum pressure plate 503 fit the inner side of the gums of the lower jaw. A triangular structure is formed between the gum pressure plate 503, the shaping rod 502 and the support rod 2 to achieve stable support for the opener, and the doctor treats the teeth in the operating cavity formed by the opener.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
