Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary instruments, in particular to an orthodontic mouth opener. Background Art

[0002] In the field of oral medicine, an opener (also known as a mouth opener) is an important auxiliary device that assists doctors in orthodontic treatment, oral examinations and oral surgery.

[0003] Most existing mouth openers are of a single size or fixed structure, relying on the elasticity or rigid tension of the material to maintain the open state. However, the oral anatomical structures of children, adolescents and adults are significantly different (such as dental arch width and degree of jaw development). Single-sized or fixed-structure mouth openers lack an adjustable mechanism and are difficult to accurately adapt to the oral size of patients of different body shapes. This not only reduces patient comfort, but may even cause fatigue of the temporomandibular joint or mucosal damage. For example, children have a small oral space, and using a single-sized or fixed-structure mouth opener may cause soft tissue compression due to excessive opening; and during adult orthodontic treatment, a fixed mouth opener may not be able to stably maintain the degree of opening due to insufficient tension.

[0004] Furthermore, existing mouth openers are often fixed to the dentition through friction or simple snap-on mechanisms. During orthodontic treatment, patients may experience unconscious oral muscle movements. Furthermore, the moist oral environment, unconscious swallowing, or tongue movements can easily cause the device to shift. For example, a slipping mouth opener can squeeze the lip and cheek mucosa, causing iatrogenic damage. If it falls into the pharynx, it can even pose a risk of suffocation. Summary of the Invention

[0021] 1. The present invention provides an orthodontic mouth opener, which uses an adjustment component to adjust the opening distance of a pair of opening components to adapt to different oral sizes. The support bracket position of the opening component is adjustable to achieve adjustment of different support positions. The clamping component clamps and fixes the teeth in the opening position to prevent the opening component from accidentally sliding / slipping off. The base of the adjustment component is rotatably connected to the main shaft, and the main shaft is fixedly connected to the adjustment knob. The main shaft is connected to a pair of linkage sliders that are slidably connected to the base through threads with opposite rotation directions. When the adjustment knob is rotated, the pair of linkage sliders move linearly toward each other along the axial direction of the main shaft under the driving action of the threads and the restriction of the base. The pair of opening components are respectively connected to the pair of linkage sliders, that is, by rotating the adjustment knob, the relative distance of the pair of opening components can be adjusted. The adjustment is convenient and fast, and the threads have self-locking ability. After adjusting to the specified position, the relative position of the pair of opening components is stable to ensure the opening and / or support effect of the oral part. The base of the opening component is connected to the support bracket, and the support bracket is provided with a groove for placing the teeth. When opening and / or supporting, the teeth are placed in the groove of the supporting tray, so that the contact effect between the supporting tray and the teeth in the supporting position is good, thereby ensuring the opening and / or supporting effect of the opening component on the mouth; the air bag of the clamping component is arranged on the inner wall of the groove of the supporting tray, the eccentric cam is fixedly connected to the main shaft, and the air inlet component of the inflation component abuts the annular end face of the eccentric cam, and the air bag is connected to the air outlet end of the inflation component. When the adjustment knob is turned to adjust the relative distance between a pair of expansion components, the eccentric cam rotates accordingly under the action of the main shaft. The eccentric cam rotates and periodically presses the inflation component to inflate the air bag. After the air bag is inflated, it expands, so that the width of the groove where the supporting tray for placing the teeth becomes narrower, thereby achieving clamping and fixation of the teeth in the supporting position.

[0022] 2. An oral orthodontic opener provided by the present invention uses a guiding member to connect the base plate and the linkage slider, so that the movement states of the three are the same. A first through groove is opened on the base, and the guiding member slides through the through groove. Under the action of the first groove, the guiding member guides and limits the movement of the linkage slider and the base plate, making the process of adjusting a pair of撑开组件 smooth; the adjusting seat is used to connect the supporting dental tray and the base plate to facilitate the adjustment of the relative position of the supporting dental tray, so as to realize the adjustment of the supporting position. An adjustment groove is opened on the base plate, and the locking bolt screwed to the adjusting seat passes through the adjustment groove. The adjustment bolt can be used for the relative locking and / or relative sliding of the adjusting seat (supporting dental tray) and the base plate, and can also limit and guide the adjustment process of the adjusting seat (supporting dental tray) relative to the base plate to ensure the smoothness and functionality of the adjustment process, and can effectively improve the accuracy of the adjustment position.

[0023] 3. An oral orthodontic opener provided by the present invention sets the base plate, the supporting dental tray and the adjustment groove to be arc-shaped, and a pair of base plates and a pair of supporting dental trays are in a "mouth" shape, which conforms to ergonomics in structure. The arc centers of the adjustment groove, the base plate and the supporting dental tray are concentric. No matter how it is adjusted, the supporting dental tray always adapts to the human mouth, making the contact effect between the supporting dental tray and the teeth at the supporting position good and the contact area large, which can effectively improve the comfort when opening the mouth and / or supporting the mouth; an irradiation lamp is arranged on the side wall of the supporting dental tray. With the help of the light of the irradiation lamp, medical staff can easily observe the patient's oral cavity and perform orthodontic operations. The irradiation lamp is an LED lamp with a built-in battery, and the overall structure is simple and the function is reliable.

[0024] It should be noted that the term "撑开组件" in the original text seems to be an incorrect or incomplete expression. It may need to be further clarified or corrected in the original context.4. An orthodontic opener provided by the present invention utilizes a linkage to connect the driving end of the air intake assembly and the eccentric cam, an annular groove is provided on the annular end surface of the cam, the linkage is connected to an arc-shaped slider slidably arranged on the inner side of the annular groove, the cooperation of the annular groove and the arc-shaped slider makes the connection between the linkage and the eccentric cam reliable, a second through groove is provided on the base, the linkage slides through the second through groove, the second through groove guides and limits the movement of the linkage, so that the eccentric cam can inflate the airbag evenly and smoothly as the main shaft rotates; a connecting cylinder is fixed on the base, the inflation assembly is arranged on the inner side of the connecting cylinder, the outer side of the connecting cylinder is connected to the outer cylinder through a threaded sleeve, and the outer cylinder shields the inflation assembly, The protection makes the outer tube of the entire mouth opener neat and simple, and also facilitates the installation, debugging and correction of the inflation component to ensure the functionality of the inflation component. The outer tube can also be used as a grip handle for the entire mouth opener. When the doctor opens and / or stretches the patient's mouth, he can hold the outer tube with one hand and turn the adjustment knob with the other hand. It is simple and easy to learn, which improves the convenience of operating the mouth opener. An air nozzle is set on the airbag and a control valve is connected to the air guide tube to facilitate the control of the inflation state of the airbag (whether to inflate it to support the clamping and fixation of the teeth in the position, control the amount of inflation to adapt to the clamping force, etc.) to meet different clinical needs.
