Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an oral cavity auxiliary opening device for oral cavity examination. Background Art

[0002] Oral examination is a very important part of the medical field and is of great significance for the prevention and treatment of oral diseases. The oral cavity is the channel for daily eating, and it is easy to cause various oral problems due to improper daily cleaning and care. The oral care department is a department that examines and treats various oral problems. When medical workers in the oral care department conduct internal oral examinations on oral patients, they generally require the patients to lie on the examination platform, keep their heads tilted forward and backward, sway left and right, and open their mouths, etc., to facilitate the doctor's examination.

[0003] At present, when assisting in stretching the oral cavity, doctors usually use oral stretch forceps to assist in support. Most of the stretching degrees are fixed, which makes it inconvenient to adjust the device according to the maximum degree of the patient's oral opening. It is not convenient to use and cannot meet the various needs of medical staff. In addition, the existing stretching device cannot limit the patient's tongue after stretching the mouth. The patient will unconsciously move the tongue during the oral examination, which interferes with the examination. At the same time, a large amount of saliva will be secreted in the mouth during a long period of opening the mouth. In order to avoid interfering with the examination, medical staff need to use an aspirator for suction, which is cumbersome and increases the examination time, increases the time the patient's mouth is open, and causes discomfort to the patient.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. In addition, the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1

[0030] In order to solve the problem that doctors currently use oral dilators to assist in support, most of the dilators have a fixed degree of dilator opening, which makes it inconvenient to adjust the device according to the maximum degree of oral opening of the patient, and is not convenient to use and cannot meet the various needs of medical staff. Figures 1 to 4 As shown, an oral auxiliary opening device for oral examination is provided, comprising an upper tooth plate 1 and a lower tooth plate 2;

[0031] Guide columns 3 connected to adjustment columns 4 are respectively arranged on both sides between the upper tooth plate 1 and the lower tooth plate 2. The adjustment columns 4 are used to adjust the distance between the upper tooth plate 1 and the lower tooth plate 2, and the guide columns 3 are used for telescopic guidance.

[0032] The guide column 3 includes a slide bar 301, a sleeve 302, and a spring 303. The bottom of the slide bar 301 is connected to the lower tooth plate 2. A block 3011 is provided on the upper part of the slide bar 301 and is slidably sleeved in the slot 3021 of the sleeve 302. A spring 303 is provided between the top of the slide bar 301 and the top of the sleeve 302 for fixed connection. The spring 303 is in a compressed state at any time, and the top of the sleeve 302 is connected to the upper tooth plate 1.

[0033] The guide column 3 can only be extended and retracted in the vertical direction under the sliding limit of the block 3011 and the slot 3021, and because the spring 303 cannot restore its original length within the guide column 3 and is in a compressed state, there is a supporting force between the slide rod 301 and the slide sleeve 302.

[0034] The adjusting column 4 includes a first threaded rod 401 and a threaded sleeve rod 402. The end of the first threaded rod 401 is rotatably connected to the inside of the lower toothed plate 2. The threaded sleeve rod 402 is threadedly connected to the upper part of the first threaded rod 401, and the top of the threaded sleeve rod 402 is fixedly connected to the upper toothed plate 1. The end of the first threaded rod 401 is rotatable inside the lower toothed plate 2 through a bearing 901, and is also connected to a first bevel gear 403 at the end. The first bevel gear 403 is meshed with a second bevel gear 404. The center of the second bevel gear 404 is fixedly connected to one end of the adjusting rod 6, and the other end of the adjusting rod 6 can be rotated to drive the rotation of the second bevel gear 404.

[0035] When adjusting the adjusting column 4, the adjusting rod 6 is rotated to rotate the second bevel gear 404, driving the meshing first bevel gear 403 to rotate. Under the rotation of the first bevel gear 403, the first threaded rod 401 rotates. Under the limitation of the guide column 3, the threaded sleeve rod 402 cannot drive the upper tooth plate 1 to follow the rotation and can only extend and retract under the action of the thread. The device is adjusted according to the maximum degree of opening of the patient's mouth, and the patient's mouth is opened to the maximum to facilitate examination.

[0036] Example 2

[0037] Based on Example 1, in order to solve the problem that the existing opening device cannot limit the patient's tongue after opening the mouth, and the patient will unconsciously move the tongue during the oral examination, causing interference to the examination, refer to Figures 5 and 6 As shown, a connecting plate 5 is fixedly connected to the outer end of the lower tooth plate 2, a slide seat 8 is slidably connected in a slide rail 502 opened in the middle of the connecting plate 5, a tongue-blocking plate 7 is connected to the slide seat 8, and the tongue-blocking plate 7 is located between the guide column 3 and the adjustment column 4;

[0038] A through hole 501 is opened in the middle of the connecting plate 5, and slide rails 502 are arranged on both sides of the through hole 501 to connect with the slide seat 8; the middle of the slide seat 8 is threadedly connected with the second threaded rod 9; one end of the second threaded rod 9 is rotatably connected to the inside of the lower tooth plate 2 through a bearing 901, and the other end passes through the connecting plate 5 and is rotatably connected to the edge of the connecting plate 5 through a bearing 901.

[0039] According to different patients, the second threaded rod 9 is rotated to adjust the slide seat 8 to slide on the slide rail 502, so that the tongue block 7 moves and extends into the oral cavity to limit and block the tongue.

[0040] A guide rod 14 and a third threaded rod 15 are provided at the bottom of the head end of the tongue stop plate 7. The top of the guide rod 14 is fixedly connected to the tongue stop plate 7, and the guide rod 14 passes through one side of the slide seat 8 and is slidably connected to the slide seat 8; the top of the third threaded rod 15 is rotatably connected to the inside of the tongue stop plate 7, and the third threaded rod 15 passes through the other side of the slide seat 8 and is threadedly connected to the inside of the slide seat 8.

[0041] By adjusting the rotation of the third threaded rod 15, under the limiting action of the guide rod 14, the tongue stopper 7 can only be displaced in the vertical direction. Under the rotational connection between the top of the third threaded rod 15 and the inside of the tongue stopper 7, the rotation of the third threaded rod 15 is converted into the movement of the tongue stopper 7, so that the height of the tongue stopper 7 is adjusted according to the oral conditions of different patients to completely restrict the movement of the tongue and avoid interference with the examination caused by unconscious movement of the tongue.

[0042] In order to prevent the tongue guard 7 from causing pressure or scratches on the patient's tongue, a flexible pad 701 is provided on the upper and lower surfaces of the end of the tongue guard 7, and the flexible covering pad is in contact with the patient's tongue.

[0043] Example 3

[0044] Based on the above embodiment, in order to solve the problem that a large amount of saliva will be secreted in the mouth of the patient when the mouth is open for a long time, and in order to avoid interference with the examination, medical staff need to take the suction device 13 for suction, which is cumbersome to operate, resulting in a longer examination time, increasing the time the patient's mouth is open, and causing discomfort to the patient. A suction mechanism is symmetrically fixedly connected on both sides of the lower surface of the tongue guard 7, and the suction mechanism sucks the saliva in the mouth.

[0045] The suction mechanism includes a suction head 10 located at the lower end of the tongue baffle 7, and a plurality of suction holes 1001 are opened on the suction head 10. The suction head 10 is connected to the head end of a fixed tube 12 fixed on the lower surface of the tongue baffle 7 through a plastic tube 11, and the end of the fixed tube 12 is connected to a suction device 13.

[0046] The suction mechanism follows the adjustment of the tongue guard 7 to enter the oral cavity, and can make the suction head 10 be located at different positions on the side of the tongue by adjusting the plastic tube 11, and then the saliva secreted by the patient's mouth that has been open for a long time is sucked out through the suction device 13, avoiding the saliva from blocking the inspection line of sight and eliminating the need to take the suction device 13, thereby reducing operation time and reducing the patient's discomfort.

[0047] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to only the specific embodiments described. Obviously, many modifications and changes can be made according to the content of this specification.
