DETAILED DESCRIPTION OF THE INVENTION

[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings. It should be noted that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the drawings of the present invention and do not specifically limit the present invention.

[0043] An adjustable lip stretching device, such as Figures 1 - 8 As shown, it includes a mounting ring 1, a fixed block 2 is installed in the mounting ring 1, there are two fixed blocks 2, a threaded rod 3 is rotatably installed on the outside of the fixed block 2, the threaded rod 3 is rotatably connected to the mounting ring 1, a lifting block 4 is slidably installed between the fixed block 2 and the mounting ring 1, and the lifting blocks 4 are threadedly connected to adjacent threaded rods 3, a bite plate 5 is clamped between the lifting blocks 4, and the bite plate 5 and the lifting block 4 are a detachable connection structure, a lip frame 6 is slidably installed on the upper and lower parts of the mounting ring 1, the lip frame 6 is used to support the patient's lips, the lip frame 6 is an arc structure, and a sliding frame 7 is installed on the lip frame 6, a fixed sleeve 8 is installed on the left and right rear sides of the mounting ring 1, the sliding frame 7 is slidably connected to the adjacent fixed sleeve 8, a spring 9 is sleeved on the corresponding sliding frame 7, one end of the spring 9 is connected to the adjacent sliding frame 7, and the other end is connected to the adjacent fixed sleeve 8, a clamping ring 10 is rotatably connected to the sliding frame 7, and a clamping ring 10 is rotatably connected to the sliding frame 7. The ring 10 is slidably connected to the adjacent fixed sleeve 8, and a guide groove is opened on the fixed sleeve 8. The snap ring 10 can slide in the corresponding guide groove. Rotating the snap ring 10 can unlock the corresponding sliding frame 7 and slide out directly under the action of the spring 9. The sliding member 11 is slidably installed on the mounting ring 1, and the sliding member 11 can be pushed by the adjacent sliding frame 7. The fixed rod 12 is slidably connected to the bite plate 5 for guiding the bite plate 5, and the fixed rod 12 can be pushed by the sliding member 11. The baffle 13 is installed between the fixed block 2 and the mounting ring 1. The baffle 13 is used to block and protect the threaded rod 3. The through hole 14 is set on the left and right parts of the mounting ring 1, and the through hole 14 is used to guide the catheter. The elastic member 15 is correspondingly arranged in the through hole 14, and the elastic member 15 is used to compress and limit the catheter. The connecting plate 16 is installed on the left and right sides of the mounting ring 1, and the connecting plate 16 is convenient for medical staff to hold it in hand.

[0044] It should be noted that the mounting ring 1 serves as the main frame, and the connecting plates 16 on the left and right sides provide hand-held fulcrums. When the operator rotates the threaded rod 3, the threaded rod 3 drives the lifting block 4 to slide in the track formed by the fixed block 2 and the mounting ring 1 through the rotational connection between the fixed block 2 and the mounting ring 1. The bite plate 5 is linked to the lifting block 4 through the clamping structure to achieve vertical height adjustment. The baffle 13 forms a protective barrier on the periphery of the threaded rod 3 to prevent interference from foreign objects, so that the patient can quickly open his lips and cooperate with medical staff for treatment.

[0045] It should be noted that when it is not necessary for the patient to fully open the lips, and only the patient's lips need to be opened, the sliding frame 7 can be unlocked by rotating the snap ring 10. In the initial state, the spring 9 is under stress. At this time, under the action of the spring 9, the sliding frame 7 will move forward, thereby pushing the sliding member 11 to move, so that the sliding member 11 pushes the fixed rod 12, and then the occlusal plate 5 quickly disengages from the mounting ring 1. At the same time, as the sliding frame 7 slides out, it will drive the lip clamping frame 6 to slide out, so as to open the patient's lips through the lip clamping frame 6, facilitating the medical staff to observe and treat.

[0046] It should be noted that the through hole 14 is embedded with an elastic silica gel ring to form a three-point clamping structure. When the catheter is inserted, the elastic member 15 generates a progressive clamping force. The through hole 14 can guide multiple medical catheters at the same time, and prevent the catheter from directly entering the patient's oral cavity from the front, so as to prevent the influence on the observation operation.

[0047] The above are only examples of the present invention and are not intended to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art of those skilled in the art.
