Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical apparatus and instruments, concretely relates to a mouth opener. BACKGROUND

[0002] The atlantoaxial joint is composed of the atlas and the axis and the joint and ligament therebetween, including the atlantoaxial anterior membrane, the atlantoaxial posterior membrane and the transverse ligament of the atlas, and is responsible for maintaining the stability of the joint. The atlas has no vertebral body and is composed of the anterior arch, the posterior arch and the lateral mass; the axis has a dentiform process on the upper part of the vertebral body and forms a joint with the anterior arch of the atlas. The atlantoaxial joint is the key structure for the rotation and partial flexion and extension of the cervical spine. Atlantoaxial dislocation is a serious disease, which is often caused by trauma, congenital malformation, inflammation or tumor, and is manifested as neck pain, limited activity, nerve compression symptoms, and severe cases can cause limb numbness, weakness, and even dizziness, blurred vision and other symptoms of vertebral artery insufficiency.

[0003] The cervical spine open X-ray film is an important means for diagnosing atlantoaxial dislocation, which can clearly show the positional relationship between the atlas and the axis, determine the type and degree of dislocation, and the integrity of the dentiform process and ligament. By measuring the atlanto-dental distance and atlantoaxial joint space, the dislocation condition can be evaluated. The open X-ray film has the advantages of simple operation, low cost, fast output, etc., and is suitable for use in primary hospitals. It can provide more comprehensive information for diagnosis in combination with CT and MRI. However, the patient usually needs to keep the body straight and the head to be tilted backward during the examination to fully expose the anatomical structure of the atlas and the axis to ensure that the image is clear and accurate. However, due to tension, anxiety or other physiological factors, the patient may not open his mouth fully or the posture may not be stable, which can affect the quality and clarity of the imaging. The degree of cooperation of the patient is crucial to the accuracy of the image, but tension can cause muscle tension or involuntary movements, resulting in blurred images or incomplete display of important details. In addition, some patients cannot maintain the backward angle of the head due to physiological limitations or pain, which also hinders the clear presentation of the atlantoaxial joint.

[0004] Therefore, the utility model is provided. CONTENT OF THE UTILITY MODEL

[0026] The utility model will be further described in detail in combination with the drawings.

[0027] Please refer to Figs. 1-3 It is shown that in the embodiment, a mouth opener is provided, which comprises an upper wing 1 of a hand-held part and a lower wing 2 of the hand-held part, the upper wing 1 of the hand-held part and the lower wing 2 of the hand-held part are arranged in parallel from top to bottom, which is used for medical staff to hold the mouth opener for assistance, and an end between the upper wing 1 of the hand-held part and the lower wing 2 of the hand-held part is fixedly connected with a connecting plate 3; the parallel arrangement of the upper and lower wings of the hand-held part facilitates the medical staff to hold the mouth opener stably and comfortably, reducing the risk of sliding or dropping in operation. The arrangement of the connecting plate 3 increases the stability of the overall structure, ensuring that the mouth opener will not be deformed due to stress during insertion and fixation.

[0028] The upper and lower occlusal parts 4 and 5 are arranged on one side of the connecting plate 3, and each has an arc-shaped structure above it, which faces the upper and lower wings 1 and 2 of the hand-held part, respectively. The arc-shaped structure helps better fit the patient's teeth, making the mouth opener more stable in the right position during use. The layout of the occlusal part towards the hand-held part facilitates visual and tactile alignment during operation, making it easier for medical staff to place and adjust correctly.

[0029] The tongue-pressing part 6 is located below the lower occlusal part 5 and extends into the oral cavity, used to press the tongue down to avoid blocking the X-ray path when the patient opens his mouth. The design of the tongue-pressing part prevents the patient's tongue from unintentionally lifting during the shooting process, ensuring that the incident path of the X-ray remains unobstructed, avoiding image blur or distortion, and improving the clarity and quality of X-ray imaging.

[0030] Optionally, the upper and lower occlusal parts 4 and 5 form a groove structure 7 for fitting the patient's teeth at the part where they are connected to the connecting plate 3. The groove structure 7 helps better fit the patient's teeth, preventing sliding or displacement. This design not only improves the stability of fixation, but also maintains the position of the device when the patient makes a slight involuntary movement, reducing discomfort and the need for repositioning.

[0031] Optionally, the upper and lower wings 1 and 2 of the hand-held part are connected to the upper and lower occlusal parts 4 and 5 through a curved transition. The curved transition design reduces irritation to the soft tissues inside the oral cavity, improving comfort during placement. This can reduce the patient's discomfort during use and help medical staff smoothly and quickly place the device in place, saving operation time.

[0032] Optionally, the upper and lower wings 1 and 2 of the hand-held part have hand-holding grooves 8 on their outer edges. The hand-holding grooves 8 provide additional finger placement areas, improving the anti-slip property and comfort of operation when gripping.

[0033] Optionally, a ventilation space 9 is formed between two adjacent connecting plates 3, and a vertical connecting part 10 is arranged between the upper and lower occlusal parts 4 and 5 on one side of the connecting plate 3. A gas dispersion space 11 is formed between the upper and lower occlusal parts 4 and 5 and communicates with the ventilation space 9. The ventilation space 9 improves air circulation in the patient's oral cavity, preventing suffocation or discomfort during long-term use. The gas dispersion space 11 ensures that air can flow between the upper and lower occlusal parts, helping to relieve the patient's tension and improve the overall use experience.

[0034] Optionally, the edges of the arc-shaped structures of the upper dental occlusion portion 4 and the lower dental occlusion portion 5 are provided with rounded corner structures, and the two sides of the tongue depressor are provided with arc-shaped portions 12. The rounded corner structures at the edges of the upper dental occlusion portion 4 and the lower dental occlusion portion 5 avoid the irritation or scratches that may be caused by sharp edges, and reduce the discomfort or potential harm when the device contacts the soft tissues in the oral cavity. In addition, the arc-shaped and rounded corner structures effectively prevent damage to the oral tissues that may be caused by the occlusion device or the tongue depression operation. When the device is placed or adjusted, the smooth edges reduce the pressure and friction on the gums, tongue and other soft tissues in the oral cavity, ensuring safety.

[0035] Working principle: When in use, the medical staff begins to measure the distance and height of the patient's upper and lower teeth to select the appropriate auxiliary mouth opener. After the measurement is completed, the medical staff fixes the patient's lower jaw with the left hand to keep it in the central position and prevent any lateral deviation from affecting imaging. Then, the medical staff selects the auxiliary mouth opener that matches the measured height and holds the upper wing 1 and the lower wing of the hand-held part of the mouth opener with the right thumb and index finger, ready to place it in the patient's mouth.

[0036] When inserting the auxiliary mouth opener into the patient's mouth, the medical staff ensures that the tongue depressor is pressed under the patient's tongue to keep the tongue stable and prevent it from blocking the incident path of X-rays, which is crucial for the clarity of the image. After the mouth opener is in place, the medical staff will instruct the patient to gently close the upper and lower teeth so that they fit the upper dental occlusion portion 4 and the lower dental occlusion portion 5, thereby reducing discomfort and muscle tension caused by prolonged mouth opening.

[0037] Subsequently, the medical staff checks the patient's mouth opening posture, especially whether the mandible is in the central position and whether the mouth opening angle is suitable for X-ray shooting. Only when it is confirmed that the mandible is in the central position and the mouth opening angle is correct, can the shooting operation be performed to ensure that the X-rays can clearly penetrate and image the structure of the atlas and the pivot vertebra. The entire operation process maintains the stability of the patient's oral cavity and tongue through the reasonable use of the auxiliary mouth opener, reducing the imaging distortion caused by non-standard posture.

[0038] The utility model is not limited to the above-mentioned embodiment, anyone should know that the structural change made under the inspiration of the utility model, any technical scheme with the same or similar technical scheme as the utility model falls within the protection scope of the utility model. The technical, shape and structure parts not described in detail in the utility model are all known technologies.
