Description

Technical Field

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

[0002] The cavity in the mouth is composed of two lips, two cheeks, hard palate, soft palate, etc. There are teeth, tongue, salivary glands and other organs in the oral cavity. The oral cavity is divided into the proper oral cavity inside the dentition and the oral vestibule outside the teeth with the dentition as the dividing line. When medical staff examine the patient's mouth, they usually ask the patient to open his mouth wide. However, due to the particularity of the oral cavity, some parts inside the oral cavity are not easy to be examined, and it is more laborious for the patient to open his mouth for a long time, so it is difficult for the patient's mouth to keep an open posture for a long time. Therefore, a distraction device is generally used to expand the patient's teeth and mouth to ensure normal examination.

[0003] The existing opening device mainly consists of an upper and lower part, and the angle between the upper and lower tooth sleeves is adjusted to change the patient's oral angle for the convenience of medical staff's inspection. The opening device in the prior art mainly consists of an upper tooth sleeve and a lower tooth sleeve, and the angle between the upper and lower tooth sleeves is adjustable to adjust the degree of oral opening.

[0004] The upper and lower tooth sleeves of the existing oral expander are adjusted mechanically by hard contact, and over-adjustment can easily lead to excessive expansion of the patient's mouth and tearing injury. Therefore, an oral expansion device using airbag adjustment is proposed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an oral dilating device, which has the function of, after being adjusted to a certain angle, causing the airbag to deform when the patient resists the upper and lower tooth sleeves, thereby reducing damage to the patient's oral cavity, achieving the advantage of protection, and solving the problem of tearing damage to the patient's oral cavity caused by rigid angle adjustment during the dilating process.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an oral opening device, which includes an upper tooth brace and a lower tooth brace, wherein one end of the upper tooth brace and the lower tooth brace is respectively provided with a support block one and a support block two, a connecting block is provided inside the support block one, a ring body two is provided inside the connecting block, a ring body one is provided outside the ring body two, a rod body is rotatably connected to the inside of the ring body two, a telescopic tube is provided between the ring body two and the ring body one, and when the telescopic tube is connected to the air source, the telescopic tube will push the rod body to rotate, and the rod body drives the upper tooth brace to rotate to change the angle between the upper tooth brace and the lower tooth brace.

[0007] As a further preferred embodiment of the present invention, the inner side walls of the alveoli of the upper tooth brace and the lower tooth brace are respectively provided with an airbag cushion 1 and an airbag cushion 2.

[0008] As a further preferred embodiment of the present invention, two ends of the airbag cushion one are respectively provided with a tube body three, and two ends of the airbag cushion two are respectively provided with a tube body seven.

[0009] As a further preferred embodiment of the present invention, a three-way pipe 1 is arranged inside the connecting block, and the three-way pipe 1 connects the pipe body 4, the pipe body 5 and the pipe body 3 respectively, and the pipe body 4 is connected to the telescopic pipe.

[0010] As a further preferred embodiment of the present invention, a three-way pipe 2 is provided inside the support block 2, and the three-way pipe 2 is respectively connected to the tube body 6, the tube body 5 and the tube body 2, and the tube body 6 is connected to the tube body 7. The support block 2 is provided with two three-way pipes, and the other three-way pipe 2 in the support block 2 is connected to the tube body 1.

[0011] As a further preferred embodiment of the present invention, a second slide groove is provided between the second ring body and the first ring body, a sliding block is provided at one end of the telescopic tube, and the sliding block is slidably disposed in the second slide groove.

[0012] As a further preferred embodiment of the present invention, a sliding groove three is provided on the outer side wall of the ring body one, and the rod body passes through the sliding groove three.

[0013] As a further preferred embodiment of this solution, the telescopic tube is an arc-shaped structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The oral opening device adopts a telescopic tube to connect to the external air source, which can change the position of the telescopic tube in the two rings. At this time, one end of the telescopic tube pushes one side of the rod body, so that the rod body drives the upper tooth sleeve to rotate. The rotation of the upper tooth sleeve opens the patient's teeth, which is convenient for the doctor's examination.

[0016] 2. When the patient feels discomfort during the opening of the upper braces, the oral opening device stops inputting gas into the telescopic tube, and the patient can bite the upper and lower braces, and the telescopic tube will deform, thereby reducing the damage to the patient's oral cavity when adjusting the upper braces.

[0017] 3. The oral opening device is provided with airbag cushions in both the upper and lower braces. The patient's teeth and the braces are connected in a flexible manner, which further reduces the damage to the teeth caused by the braces and once again reduces the damage to the patient's oral cavity when adjusting the upper braces.

[0018] 4. The oral cavity opening device is provided with two telescopic tubes on both sides of the upper dental brace, and air is taken in by the two telescopic tubes at the same time, thereby ensuring the uniform rotation of the upper dental brace. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] By connecting the telescopic tube 450 to an external air source, the position of the telescopic tube 450 in the two ring bodies can be changed. At this time, one end of the telescopic tube 450 pushes one side of the rod body, so that the rod body drives the upper dental brace to rotate. The rotation of the upper dental brace opens the patient's teeth to facilitate the doctor's examination. When contracted, the telescopic tube 450 is similar to the structure of a bellows. The telescopic length is changed by connecting to an air source. The material is rubber and has a certain elasticity.

[0036] In some embodiments, the inner side walls of the upper tooth brace 100 and the lower tooth brace 200 are respectively provided with an airbag cushion 1 300 and an airbag cushion 2 600 .

[0037] Specifically, airbag cushions are provided in both the upper and lower braces, and the patient's teeth and the braces are connected in a flexible manner, which further reduces the damage to the teeth caused by the braces and once again reduces the damage to the patient's oral cavity when adjusting the upper braces.

[0038] In some embodiments, two ends of the airbag cushion 1 300 are respectively provided with a tube body 310 , and two ends of the airbag cushion 2 600 are respectively provided with a tube body 7 610 .

[0039] Specifically, while the telescopic tube 450 is taking in air, the gas can be introduced into the two airbag cushions through the arrangement of the tube body three 310 and the arrangement of the tube body seven 610 , thereby enabling one gas source to drive the airbag cushions and the telescopic tube 450 .

[0040] In some embodiments, a three-way pipe 470 is disposed inside the connection block 410, and the three-way pipe 470 connects the tube body 480, the tube body 5 490 and the tube body 310 respectively, and the tube body 480 is connected to the telescopic tube 450.

[0041] Specifically, the three-way pipe 470 can disperse the gas into the tube body 480 respectively, and the tube body 480 can deliver gas to the telescopic tube 450, and deliver the gas into the tube body 310, so that the airbag cushion 300 can take in air, and the airbag cushion 300 and the telescopic tube 450 can obtain gas respectively, thereby starting to work.
