DETAILED DESCRIPTION

[0030] The following will be combined with the 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 An adjustable oral medical mouth opener comprises an upper pressure rod 1, one end of the upper pressure rod 1 is rotatably connected to a lower pressure rod 2, the other end of the upper pressure rod 1 is rotatably connected to a bite pressure rod 6, the upper pressure rod 1 is provided with an autonomous adjustment device 4 for adjusting the angle of the upper pressure rod 1 and the lower pressure rod 2, and the lower pressure rod 2 and the bite pressure rod 6 are both provided with bite plates 3; the autonomous adjustment device 4 comprises a bite device and a clamping device, the bite device controls the angle of the upper pressure rod 1 and the lower pressure rod 2 through the patient's bite action, and the clamping device is used to clamp the autonomously adjusted angle.

[0032] In this embodiment, the bite device includes a rotating shaft 401, which is fixed on the bite pressure rod 6, and the rotating shaft 401 is rotatably connected to the upper pressure rod 1. The rotating shaft 401 is fixedly connected to the rotating gear 402 through a sleeve, and a reversing device 403 is arranged in the rotating gear 402. The bottom of the upper pressure rod 1 is fixedly connected to a fixing plate 409, and a sliding rod 410 is slidably connected to the fixing plate 409, and one end of the sliding rod 410 is connected to the bite pressure rod 6. A contraction spring 411 is sleeved on the surface of the sliding rod 410, and the contraction spring 411 is located between the bite pressure rod 6 and the fixing plate 409, and one side of the rotating gear 402 is connected to the locking device. When the patient bites the upper and lower jaws, the bite pressure rod 6 will rotate slightly at the position of the upper pressure rod 1 through the rotating shaft 401, and the rotation limit is blocked by the fixed plate 409. During the rotation of the rotating shaft 401, the plurality of rotating teeth 4032 and the fixed teeth 4031 will be driven to form a clamping state, thereby driving the rotation of the rotating gear 402. In this way, the bite force is converted into a driving force, and the patient's autonomous and convenient angle adjustment is realized, which improves the patient's comfort.

[0033] Furthermore, the positioning device includes a rack 404, one side of which is provided with a right tooth 407, which meshes with the rotating gear 402 for transmission, and the other side of the rack 404 is provided with a positioning tooth 408, on which a positioning plate 413 is clamped, and one end of the positioning plate 413 is rotatably connected to the lower pressure rod 2. The rotation of the rotating gear 402 will drive the rack 404 to slide, and one end of the rack 404 is fixed on the upper pressure rod 1. When the rotating gear 402 rotates clockwise, it will drive the rack 404 to move upward, and then drive the upper pressure rod 1 to rotate to achieve angle control, and the other side of the rack 404 is provided with a positioning tooth 408, and the positioning tooth 408 and one side of the positioning plate 413 are engaged with teeth to achieve positioning.

[0034] Furthermore, the lower pressure rod 2 is provided with a fixed box 201, and a tension spring 412 is clamped inside the fixed box 201. One end of the tension spring 412 is clamped on one side of the positioning plate 413. When the rack 404 moves, it will squeeze the positioning plate 413 to rotate and make way, and the tension spring 412 will provide elastic force. When the rack 404 does not move, it will control the positioning plate 413 to squeeze on the positioning tooth 408 to achieve the clamping position. The other side of the positioning plate 413 is fixedly connected with a paddle 405. The setting of the paddle 405 is mainly to quickly disengage the opening device after the whole use is completed. It only needs to paddle the paddle 405 and disengage the positioning tooth 408. A limiting groove 406 is provided inside the rack 404, and the limiting groove 406 is internally slidably connected to the limiting shaft 414, and the limiting shaft 414 is fixed to the lower pressure rod 2 through a connecting piece. When the limiting shaft 414 slides in the limiting groove 406 , the sliding position of the rack 404 is limited so that the rack 404 is always meshed with the rotating gear 402 .

[0035] In addition, the reversing device 403 includes a rotating tooth 4032, one end of which is rotatably connected to the inside of the rotating shaft 401, a yielding spring 4033 is connected to the rotating tooth 4032, one end of which is connected to the rotating shaft 401, and a fixed tooth 4031 is clamped on the rotating tooth 4032, and the fixed tooth 4031 is fixed inside the rotating gear 402. There are multiple reversing devices 403, and the multiple reversing devices 403 are all circular array parts with the center of the rotating gear 402 as the symmetry axis. During the rotation of the rotating shaft 401, multiple rotating teeth 4032 will be driven to form a locking device with the fixed teeth 4031, thereby driving the rotation of the rotating gear 402. When the engaging pressure rod 6 is not under force, the elastic force of the contraction spring 411 will provide a certain upward elastic force, causing the rotating shaft 401 to reverse. In the reversed state, multiple rotating teeth 4032 will be controlled to form a pressing contact and rotation with the fixed teeth 4031, thereby compressing the giving way spring 4033. At this time, the rotating teeth 4032 and the fixed teeth 4031 form a reverse transfer effect, and finally achieve unidirectional rotation.

[0036] In addition, an observation device 5 is also included, and the observation device 5 is used to assist medical staff in observing the inside of the patient's oral cavity; the observation device 5 includes a connecting plate 501, the bottom of the connecting plate 501 is rotatably connected to a support plate 502, the support plate 502 is rotatably connected to a sleeve, the inside of the sleeve is connected to a rotating column 506, one end of the rotating column 506 is connected to a ball sleeve 507, the other end of the rotating column 506 is connected to a pull ring 505, the inside of the ball sleeve 507 is connected to a sphere 508, and the sphere 508 is connected to a reflector 503 through a connecting rod. When the patient opens his mouth, the medical staff can rotate the support plate 502 to turn the reflector 503 into the patient's oral cavity, and then the operator can view the oral cavity of the patient's upper jaw according to the reflection of the lens of the reflector 503, and at this time, the operator does not need to control the patient's head movement, thereby improving the patient's comfort.

[0037] It is worth noting that the upper and lower ends of the reflector 503 are connected with elastic ropes 510, one end of the elastic rope 510 passes through the sleeve and the pull ring 505 in sequence to connect to the limit ball 504, and the elastic rope 510 is connected to the clamp ring 509. The medical staff clamps the position of the clamp ring 509 with their fingers, pulls the elastic rope 510, and then controls the elastic rope 510 to pull the reflector 503, thereby controlling the angle of the reflector 503, making it easier for the medical staff to observe, because after changing the angle of the reflector lens 503, the position of the reflection will change accordingly, so as to facilitate the operator to check the oral cavity.

[0038] Working principle: first, when the device is in use, the upper part of the bite pressure rod 6 is inserted into the patient's oral cavity, and the half position of the lower pressure rod 2 is also located in the patient's oral cavity, and the patient's upper and lower teeth are respectively located on two bite plates 3 at the upper and lower positions, and the bite plate 3 is made of softened rubber material and is a detachable structure. It is a disposable product to avoid cross infection of the patient's oral cavity caused by repeated use. The rubber material is soft, which makes the patient more comfortable when biting and will not cause damage to the teeth. Later, when it is necessary to adjust the angle of the opener, the patient's upper and lower jaws bite, and the bite pressure rod 6 will rotate slightly at the position of the upper pressure rod 1 through the rotating shaft 401, and the rotation limit is blocked by the fixed plate 409. During the rotation of the rotating shaft 401, multiple rotating teeth 4032 will be driven to form a clamping state with the fixed teeth 4031, thereby driving the rotation of the rotating gear 402. When the bite pressure rod 6 is not under force, it will be subject to the elastic force of the contraction spring 411, which will provide a certain upward elastic force, so that When the rotating shaft 401 is reversed, the plurality of rotating teeth 4032 and the fixed teeth 4031 are controlled to form a contact and rotation with each other, thereby compressing the giving way spring 4033. At this time, the rotating teeth 4032 and the fixed teeth 4031 form a reverse displacement effect, and finally one-way rotation is achieved to control the rotation of the rotating gear 402. The rotation of the rotating gear 402 will drive the rack 404 to slide, and one end of the rack 404 is fixed on the upper pressure rod 1. When the rotating gear 402 rotates clockwise, it will drive The rack 404 moves upward, thereby driving the upper pressure rod 1 to rotate to achieve angle control, and the other side of the rack 404 is provided with a positioning tooth 408, and the positioning tooth 408 and one side of the positioning plate 413 are engaged with teeth to achieve positioning, ensuring that the positions of the upper pressure rod 1 and the lower pressure rod 2 after the angle adjustment are fixed. When the rack 404 moves, it will squeeze the positioning plate 413 to rotate and give way, and the tension spring 412 will provide elastic force. When the rack 404 does not move, it will control the positioning plate 413 to squeeze on the positioning tooth 408 to achieve locking. When the limit shaft 414 is set to slide at the position of the limit groove 406, it is to limit the sliding direction of the rack 404 so that it always meshes with the rotating gear 402. The overall angle is adjusted in this way of upper and lower bite. When the patient thinks that he has reached the limit of the opening, he does not need to bite again, so the initiative is in the patient's position, and the upper and lower bite control method is more convenient and simple.After the patient opens his mouth, the medical staff can rotate the support plate 502 to turn the reflector 503 into the patient's oral cavity. After that, the operator can view the oral cavity of the patient's upper jaw according to the reflection of the lens of the reflector 503. At this time, the operator does not need to control the patient's head movement, which improves the patient's comfort. The medical staff clamps the position of the clamp ring 509 with their fingers, pulls the elastic rope 510, and then controls the elastic rope 510 to pull the reflector 503, thereby controlling the angle of the reflector 503, making it easier for the medical staff to observe, because after changing the angle of the reflector lens 503, the position of the reflection will change accordingly, which is convenient for the operator to check the oral cavity, and the entire rotating column 506 can be rotated, thereby driving the reflector 503 to rotate, and finally realizing multi-directional reflection detection of the oral cavity position. When the observation device 5 is not used, it is only necessary to rotate the support plate 502 to turn it out of the patient's oral cavity.
