Description

Technical Field

[0001] The utility model relates to the technical field of oral treatment auxiliary tools, and more specifically to an oral dental pulp disease treatment auxiliary device. Background Art

[0002] Protecting oral health is critical to preventing oral diseases. In traditional oral prevention and treatment processes, patients are usually required to open their mouths and support and keep their mouths open by themselves to facilitate operation by medical staff. Therefore, the patient's mouth often suffers from muscle fatigue due to the open mouth but no support. In response to this, the prior art has designed and developed some auxiliary devices for supporting the patient's oral opening, such as the Chinese utility model patent with publication number CN216455442U, entitled an oral dental pulp disease treatment auxiliary sleeve. The patent discloses supporting the patient's oral cavity by rotating the connected upper and lower braces, and adjusting the opening and closing size of the upper and lower braces by a fastening screw. However, when the auxiliary sleeve is placed in the patient's mouth, the fastening screw used for adjustment is located on the inside of the oral cavity, which is difficult to reach in and adjust. It can only be adjusted before being placed in the oral cavity. This may result in the opening and closing angle between the upper and lower braces not being adjusted properly, and needs to be taken out and adjusted again. Such operation is relatively cumbersome, so there are still obvious limitations in actual application, which urgently needs to be improved. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0025] The utility model is implemented as follows Figures 1 to 5 As shown in the figure, an oral dental endodontic treatment aid comprises an upper brace 1 and a lower brace 2; the rear portion of the upper brace 1 is hinged to the rear portion of the lower brace 2, and a screw 3 is hinged on the front lower surface of the upper brace 1; a sleeve 4 is rotatably provided on the front upper surface of the lower brace 2, and the sleeve 4 rotates relatively on the front upper surface of the lower brace 2, and an internal thread matched with the thread of the screw 3 is provided in the sleeve 4, and one end of the screw 3 away from the upper brace 1 is inserted into the sleeve 4 and connected with the sleeve 4 thread.

[0026] Specifically, in this embodiment, the upper brace 1 and the lower brace 2 are both curved and have openings, and the openings of the curved upper brace 1 and the lower brace 2 are both facing backward. The degree of the curved curvature of the upper brace 1 and the lower brace 2 is based on the curvature trend that can adapt to the arrangement of teeth and gums in the universal oral cavity, and is not specifically limited here.

[0027] The interior of the sleeve 4 is hollow, and the end surface of the top end of the sleeve 4 (i.e. the end of the sleeve 4 away from the lower brace 2) is connected with the interior of the sleeve 4 for the screw 3 to be inserted.

[0028] In order to facilitate medical staff to perform operations such as removing dental pulp pus, the upper braces 1 and the lower braces 2 should also be provided with corresponding hollow grooves opposite to the teeth for relevant suction instruments to extend therein.

[0029] Specifically, in this embodiment, Figure 3 As shown in the figure, mounting holes 2101 are provided on the two opposite lower arms at the rear of the lower braces 2. For example, a fixing block 21 is provided on the upper surface of the two opposite lower arms at the rear of the lower braces 2 at a position close to the opening of the lower braces 2. The two fixing blocks 21 are correspondingly provided with receiving grooves 210 for accommodating the two opposite upper arms at the rear of the upper braces 1. The two receiving grooves 210 are also U-shaped. A mounting hole 2101 for correspondingly installing a rotating shaft is correspondingly provided on the opposite side walls of each receiving groove 210.

[0030] like Figure 4As shown in the figure, the two opposite upper arms at the rear of the upper brace 1 are provided with a rotating shaft 11 hingedly installed in the corresponding mounting hole 2101. For example, each upper arm is provided with two rotating shafts 11 corresponding to the two mounting holes 2101 in the receiving groove 210 on the same side. The size of the rotating shaft 11 is adapted to the size of the mounting hole 2101. By rotating the rotating shaft 11 on the upper brace 1 in the mounting hole 2101, the upper brace 1 and the lower brace 2 are hingedly connected.

[0031] Specifically, in this embodiment, Figure 4 and Figure 5 As shown in the figure, a protrusion 12 is fixedly provided at the central position of the front lower surface of the upper brace 1, and a U-shaped slot 120 is provided at one end of the protrusion 12 facing the lower brace 2, and the end of the screw 3 away from the sleeve 4 is hingedly installed in the U-shaped slot 120. Among them, the shape of the protrusion 12 is cylindrical. The U-shaped slot 120 is used to accommodate the end of the screw 3 away from the sleeve 4. The U-shaped slot 120 and the end of the screw 3 away from the sleeve 4 are hingedly connected to each other through a shaft provided on the screw 3. Correspondingly, holes for the shaft on the screw 3 to be rotatably installed are also provided on the two opposite side walls of the U-shaped slot 120.

[0032] Specifically, in this embodiment, Figure 2 and Figure 3 As shown in the figure, a circular groove 22 for accommodating the sleeve 4 is provided at the central position of the front upper surface of the lower brace 2, and a limiting piece 23 is fixedly provided at the central position of the inner bottom surface of the circular groove 22. One end of the sleeve 4 located in the circular groove 22 is movably inserted on the limiting piece 23, and the sleeve 4 is limited by the limiting piece 23 to rotate in the circular groove 22; the end of the sleeve 4 away from the circular groove 22 faces the screw 3 and is inserted into the screw 3.

[0033] The limiting member 23 includes a limiting block 231 and a guide post 232 fixed at the center of the bottom surface of the limiting block 231, and one end of the guide post 232 away from the limiting block 231 is fixed on the inner bottom surface of the circular groove 22. The limiting block 231 and the guide post 232 are both cylindrical. The cross-sectional shape of the limiting member 23 is T-shaped, and a gap is formed between the limiting member 23 and the inner bottom surface of the circular groove 22 to accommodate the bottom of the sleeve 4 (i.e., the end of the sleeve 4 located in the circular groove 22) to rotate therein.

[0034] Among them, a through hole 40 is opened on the end face of one end of the sleeve 4 located in the circular groove 22, the guide column 232 is penetrated in the through hole 40, and the limit block 231 is located in the sleeve 4, so that the sleeve 4 can be movably limited in the circular groove 22, that is, the sleeve 4 can rotate relative to the limit piece 23 and the circular groove 22, and then, it can drive the screw 3 to rotate in and out of the sleeve 4, so as to realize the adjustment of the opening and closing angle between the upper and lower braces 2.

[0035] Specifically, in this embodiment, the diameter of the stopper 231 is smaller than the diameter of the circular groove 22, so that the sleeve 4 can be placed in the circular groove 22. The diameter of the guide post 232 is smaller than the diameter of the stopper 231, and a gap can be formed to a large extent for accommodating the bottom of the sleeve 4 (i.e., the end of the sleeve 4 located in the circular groove 22). The diameter of the through hole 40 is larger than the diameter of the guide post 232 and smaller than the diameter of the stopper 231, and is used for the guide post 232 to pass through, and can also limit the position of the stopper 231, and is not easy to hinder the rotation of the sleeve 4.

[0036] When using the oral endodontic treatment aid of the embodiment of the utility model, the rear part of the aid is aligned with the patient's oral cavity and inserted into the patient's oral cavity so that the upper and lower braces 2 are relatively located at the upper and lower teeth. The medical staff can directly adjust the opening and closing degree of the upper and lower braces 2 through the threaded connection of the sleeve 4 and the screw 3 to further adjust the opening degree of the patient's oral cavity, thereby meeting the medical staff's detection and treatment requirements. The adjustment operation is convenient and simple, and it can be adjusted to a variety of opening and closing angles, with good overall applicability.

[0037] It should be understood that ordinary technical workers in the field can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
