The oral opening device is usually used in patients with difficulty in opening the mouth due to oral muscle tension or in people such as children of a smaller age.

[0003] In a document with the publication number CN115517619A, an oral examination and care device for stomatology is disclosed, which comprises a support frame, a first support frame, a rack and a spur gear. The support frame is at least two, and the support frame is connected on both sides of the first support frame. The support frame is connected with the rack on both sides through sliding. The first support frame has a spur gear rotatably fixed in the middle. In this device, the patient's lips can be opened and the tongue can be pressed down, thereby facilitating the doctor's examination.

[0004] However, in the above-mentioned patent, the opening block is horizontally opened by relying on the screw block structure, which has the following problems: first, each opening block needs to be adjusted separately, which is low in efficiency; second, the scope of application of this device is narrow, and the opening block can only move in one direction.

[0010] The upper side and / or the lower side of the support block is provided with the vertical support assembly.

[0011] After the technical method is used, the support block is placed in the oral cavity of the patient during use, the support block has an examination opening for the doctor to perform examination and nursing, in order to adapt to patients of different ages, the device expands the oral cavity of the patient in the transverse direction through the transverse support assembly, expands the oral cavity of the patient in the longitudinal direction through the longitudinal support assembly, and meets the needs of oral care and examination. In addition, the gear and rack structure is used as a transmission mechanism, the two racks are moved in opposite directions through the rotation of the rotating assembly, so that the transverse support block moves correspondingly, and the oral cavity of the patient is supported in the transverse direction. The longitudinal support assembly is limited in height by the longitudinal limiting piece, so as to be supported in the longitudinal direction, and the two are matched to realize rapid support of the oral cavity and improve the nursing efficiency.

[0012] In addition, the transverse support block is made of rubber material, so that the patient is more comfortable during nursing, and the transverse support block is covered with water-absorbing cotton to absorb the secreted saliva.

Specifically, since the telescopic sleeve 202 is provided with an axially oriented limiting strip 204, and the inner wall of the fourth limiting hole 106 is provided with a limiting groove 107 along the axial direction of the fourth limiting hole 106, the telescopic sleeve 202 can only move along the axial direction of the fourth limiting hole 106 and cannot rotate. In addition, the first rotating rod 201 has... A first annular limiting block 205 is provided, and a first annular groove is provided on the side wall of the third limiting hole 104. The first annular groove cooperates with the first annular limiting block 205 to restrict the axial movement of the first rotating rod 201 along the third limiting hole 104. Finally, the connection structure between the second rotating rod 203 and the telescopic sleeve 202 is consistent with the connection structure between the first rotating rod 201 and the third limiting hole 104. Through this connection, the second rotating rod 203 can rotate when the first rotating rod 201 is rotated, causing the gear 1202 to rotate, and simultaneously following the telescopic sleeve. 202 is telescopic. Therefore, under the above-mentioned constraints and the threaded connection between the first rotating rod 201 and the telescopic sleeve 202, when the first rotating rod 201 is rotated, the telescopic sleeve 202 will extend inward relative to the first rotating rod 201, thereby pushing the sliding member 13 to slide, realizing precise depth adjustment of the transverse support block 4, and at the same time causing the transverse support block 4 to expand outward, realizing synchronous adjustment of depth and transverse expansion according to the patient's age, enhancing patient comfort, and significantly reducing the outward extension length of the first rotating rod 201. Example

[0088] The difference between this embodiment and embodiment 3 is that, as Figure 10 As shown, a longitudinal limiting component 3 is also provided in the second limiting hole 103. The longitudinal limiting component 3 includes a limiting rod 301 and a slider 302. The slider 302 is slidably disposed in the second limiting hole 103. The support rod 502 is connected to the slider 302. The first elastic element 303 is provided between the lower end of the slider 302 and the bottom surface of the second limiting hole 103. A threaded hole is provided through the slider 302. One end of the limiting rod 301 is threadedly connected to the threaded hole. The other end of the limiting rod 301 passes through the side wall of the second limiting hole 103 and extends outward.

[0089] In the embodiment, another more accurate longitudinal support mode is provided for use in younger patients. First, it should be noted that in this embodiment, only one side of the longitudinal support assembly can be adjusted, and longitudinal support is achieved by longitudinal movement of the longitudinal support assembly on the upper or lower side of the support block 1. Specifically, it also relies on the elastic force of the first elastic member 303 to support the oral cavity. However, in this device, the oral mucosa of younger patients is considered to be fragile, so a longitudinal limiting assembly 3 is provided to limit the support height. In actual use, the movement of the sliding block 302 can be adjusted by turning the limiting rod 301, thereby driving the longitudinal support assembly to adjust. After the position is appropriate, the limiting rod 301 is tightened to abut against the side wall of the second limiting hole 103, thereby achieving limiting. In this embodiment, a long hole corresponding to the position of the second limiting hole 103 is provided on the front end face of the support block 1, the long hole is in communication with the second limiting hole 103, and the limiting rod 301 extends outward through the long hole.

However, when the longitudinal limiting component 3 is used, only one side of the dental tray is provided with a support rod 502. In this embodiment, the follower plate 1102 is driven to move up and down by the cam 1105 mechanism. The follower plate 1102 drives the care plate 1101 to move up and down, thereby realizing the care of the gums or teeth. Specifically, when the control button is pressed to make the drive motor 1106 rotate, it will drive the cam 1105 to rotate. The elastic force of the second elastic element 1107 makes the lower surface of the follower plate 1102 always in contact with the surface of the cam 1105, so that the cam 1105 drives the follower plate 1102 to move up and down, thereby driving the care plate 1101 to move. The massage ball and care brush provided on the care plate 1101 are used for care. Example

[0103] In another scheme, the first rotating rod 201 is rotated to move the telescopic sleeve 202 inward, so as to sequentially move the second rotating rod 203, the sliding piece 13, and the gear 1202 and the rack 1201 arranged in the sliding piece 13 inward, the movement of the rack 1201 drives the transverse support block 4 to move inward to realize depth adjustment, and meanwhile the rotation of the first rotating rod 201 drives the second rotating rod 203 to rotate, so as to drive the gear 1202 to rotate to realize expansion of the transverse support block 4.
