Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an oral fixator that is easy to support. Background Art

[0002] In the field of oral medicine, when performing orthodontic treatments, restorations, and surgical procedures, it is necessary to ensure that the patient's mouth remains stable so that the doctor can operate accurately. Traditional oral fixators (also known as oral openers) are usually used to keep the patient's mouth open and provide a stable operating platform.

[0003] If the mouth is open for a long time, the muscles will become sore. During oral treatment, in order to ensure the stability of the patient's mouth and facilitate the doctor's precise operation, an oral fixator is often required. Existing oral fixators are mostly one-piece designs, but there are the following problems during use: their structure is fixed, and each person's tooth structure is different. When fixing the patient's mouth, there will be inaccurate bite problems, resulting in slippage and other problems that affect diagnosis and treatment. In addition, the existing oral fixator structure is large, while the space in the mouth is small. After the oral fixator is inserted, the doctor's operating space is reduced, affecting diagnosis and treatment. After the mouth is opened, the corners of the mouth will be relatively closed, affecting diagnosis and treatment. Summary of the invention

Compared with the first embodiment, the lifting component 3 in this embodiment includes a push rod 303 arranged in a sliding groove 1024, a sliding block 302 slidably arranged on the push rod 303, a connecting rod 301 rotatably connected to the sliding block 302 and the plate body 201 at both ends, a guide rail 304 rotatably arranged on the sliding block 302 at one end, and a swing arm 305 rotatably arranged on the support plate 102 and rotatably connected to the guide rail 304.

[0048] Furthermore, the swing arm 305 includes a rotating part 3052 rotatably set on the blocking part 1022, a swing rod 3051 at one end of which is set on the rotating part 3052 and the other end is rotatably connected to the guide rail 304, a swing rod 3053 set on the rotating part 3052 and slidably connected to the pushing mechanism, and a sliding groove 3054 set on the swing rod 3053; the angle between the swing rod 3051 and the swing rod 3053 is an obtuse angle.

[0049] Furthermore, the pushing mechanism includes a driving component 4 which is slidably set on the swing rod 3053, and a moving component 5 which is set on the mounting plate 101 and is rotatably connected to the driving component 4; the driving component 4 includes a connecting rod 401 at one end which is rotatably set on the support plate 102 and rotates coaxially with the support plate 102 and is slidably connected to the swing rod 3053 at the other end, a support rod 403 whose two ends are respectively set at the rotational connection between the two support plates 102 and the mounting plate 101 and has a sliding groove 3 4031, a slider 405 which is slidably set in the sliding groove 3 4031, a connecting rod 3 402 which is rotatably connected to the connecting rod 401 and the slider 405 at both ends, and a connecting rod 404 which is rotatably set on the slider 405 and is rotatably connected to the moving component 5. The moving assembly 5 includes a guide frame 503 arranged on the support rod 403, a moving plate 502 slidably arranged on the guide frame 503 and rotatably connected to the connecting rod four 404, a threaded rod 501 rotatably arranged on the support rod 403 and the guide frame 503 and threadedly connected to the moving plate 502, and a handle 504 arranged on the threaded rod 501.

[0050] In this embodiment, the handle 504 rotates to drive the threaded rod 1 501 to rotate, the threaded rod 1 501 drives the movable plate 502 to move, the movable plate 502 drives the connecting rod 404 to move, the connecting rod 404 pushes the slider 2 405 to move, the slider 2 405 drives the connecting rod 3 402 to move, and the connecting rod 3 402 drives the connecting rod 2 401 to rotate when moving, and the other end of the connecting rod 2 401 slides in the sliding groove 2 3054, so that the swing arm 305 flips, the swing arm 305 drives the guide rail 304 to move, the guide rail 304 drives the sliding block 1 302 to move, the sliding block 1 302 pushes the connecting rod 1 301 to move, so that the connecting rod 1 301 can push the lifting plate 2 to flip, thereby adjusting the opening and closing angles of the patient's upper and lower jaws.

[0051] Through the above structure, the opening and closing angles of the two lifting plates 2 can be controlled at the same time, and because one end of the connecting rod 2 401 is located at the rotating connection between the support plate 102 and the mounting plate 101, no matter what position the support plate 102 is in, the transmission effect will not be destroyed. After the position of the support plate 102 changes, the inclination angle of the lifting plate 2 will also change accordingly. Therefore, when in use, it is necessary to adjust the position of the support plate 102 first, and then insert the support plate 102 into the patient's mouth, and then adjust the opening and closing angle of the lifting plate 2 through the above structure to open the patient's mouth, so that the patient can keep his mouth open, which is convenient for oral surgery or oral examination.

[0052] Embodiment 3

[0053] like Figure 1-9As shown, the present invention proposes an oral fixator that is easy to support.

[0054] In this embodiment, the fixing plate 802 and the mounting plate 101 are connected by a guide rod 801, and the fixing plate 802 can be externally connected to other fixing devices and shooting devices or treatment devices, which can be selected according to the needs of the operation, or it can be not externally connected to other devices. The patient's teeth are used to cooperate with the mounting plate 101 and the support plate 102 for fixation, and the threaded rod 2 803 is supported and fixed by the fixing plate 802, and the handle 504 is rotatably set on the fixing plate 802, so that the handle 504 can be easily rotated, and the sliding frame 804 is driven to move by the rotation of the threaded rod 2 803, and the sliding frame 804 drives the connecting rod 5 805 to move, and the connecting rod 5 805 drives the rotating rod 103 to move, so that the support plate 102 rotates, and it can be adjusted according to the structural size of the patient's teeth, so that the mounting plate 101 and the support plate 102 can be pressed on the patient's lower teeth.

[0055] The design of the present invention takes the oral structure of the patient into consideration. Through the adjustable support plate and lifting plate, it can better fit the patient's teeth, reduce pressure on oral tissues, and thus improve the patient's comfort during oral treatment.

[0056] Through the adjustment unit 8 and the pushing mechanism 5, the doctor can easily adjust the position and angle of the fixing frame, which simplifies the installation and adjustment process and improves the convenience of operation. The handle 504 is located on the fixing plate 802, which can be easily rotated, so that the device can be adjusted after being inserted into the patient's mouth.

[0057] After the patient bites the mounting plate 101, the support plate 102, and lifts the plate 2, it can adaptively clamp onto the patient's teeth, thereby enabling the device to be in a relatively fixed state without manual support, thereby freeing up a doctor and avoiding interference caused by collaborative operations of multiple doctors.
