[0002] During oral examinations or surgeries, saliva, blood, or other fluids often accumulate in the patient's mouth, affecting the surgeon's field of vision and efficiency. Because existing mouth openers cannot fix the direction of the suction tube, the tube's position is unstable during use, easily shifting or dislodging, thus failing to ensure effective fluid suction. Consequently, the primary function of existing traditional mouth openers is merely to open the patient's mouth, failing to effectively remove fluids. This not only increases the difficulty of the surgeon's operation but may also affect the smooth progress of the surgery. Therefore, there is an urgent need for a mouth opener that can fix the direction of the suction tube to improve the efficiency and ease of operation of fluid suction. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figure 1-5 The mouth opener shown includes: a mouth opener body 1, the opening portion of which is bent at a right angle; a tooth retainer 2, which is connected to the end of the opening portion of the mouth opener body 1; and an adjustable fixing device 3, which is detachably mounted on the side of the tooth retainer 2. The angle of the adjustable fixing device 3 relative to the tooth retainer 2 can be adjusted, and the adjustable fixing device 3 is used to fix the suction device. This not only maintains the basic function of the mouth opener in opening the oral cavity, but also fixes the direction of the suction tube through the adjustable fixing device 3, ensuring the effectiveness of liquid suction, maintaining a clear view of the surgical area, and featuring a simple design. It can reduce the number of steps for the surgeon, free up their hands, and improve the convenience and efficiency of the surgery. Furthermore, the adjustable fixing device 3 relative to the tooth retainer 2 can be angled, allowing the angle of the suction tube to be adjusted, enabling the doctor to flexibly adjust according to different surgical needs, thus improving the flexibility and safety of the operation. The tooth limiter 2 has a rotating groove 201 on its side, and the inner wall of the rotating groove 201 has multiple locking grooves 202 arranged in a ring array.

[0034] The adjustable fixing device 3 includes: a fixing ring 31, which is arranged in a ring shape; an installation mechanism 32, which is connected to the fixing ring 31 and is rotatably connected to the tooth retainer 2; and an elastic locking mechanism 33, which is installed inside the installation mechanism 32 and is used for interlocking and positioning between the tooth retainers 2. According to the usage position of the mouth opener body 1 on both sides of the oral cavity, the lower tooth retainer 2 is selected, and the adjustable fixing device 3 is installed on the lower tooth retainer 2 to facilitate the suction of saliva. Then, the external suction tube passes through the fixing ring 31 and is connected to the suction port of the dental chair or the central suction device of the hospital to realize the drainage of saliva. Furthermore, through the rotational engagement between the mounting mechanism 32 and the tooth retainer 2, the angle of the fixing ring 31 relative to the tooth retainer 2 can be adjusted according to the required angle of the suction tube. The elastic locking mechanism 33 facilitates positioning after adjustment, allowing for adjustment of the suction tube's direction and maintaining its stability as needed by the dentist. The mouth opener body 1 is made of metal to ensure thorough sterilization through high-temperature, high-pressure sterilization.

[0035] The fixing ring 31 has an opening and is made of elastic material. The external suction tube passes through the opening into the interior of the fixing ring 31. After the suction tube is installed inside the fixing ring 31, it will undergo slight deformation, which makes it easier to clamp the suction tube through the fixing ring 31.

[0036] The installation mechanism 32 includes: a mounting base 321, which is connected to a fixing ring 31; and a rotating disk 322, which is connected to the mounting base 321 and is rotatably connected to the inner cavity of the rotating groove 201, thereby facilitating the fixing ring 31 to drive the suction tube to rotate around the axis of the rotating disk 322.

[0037] The elastic locking mechanism 33 includes: a spring 331, which is disposed inside the mounting mechanism 32; a connecting plate 332, which is connected to both ends of the spring 331 and is slidably disposed inside the mounting mechanism 32; and a locking post 333, which is connected to one end of the connecting plate 332 and is slidably inserted into the mounting mechanism 32, and is slidably engaged with the inner cavity of the locking groove 202. The elastic locking mechanism 33 also includes: a pressing block 334, which is connected to the other end of the connecting plate 332 and is slidably inserted into the mounting mechanism 32. The spring 331 has a guide rod inside, which is fixedly installed inside the mounting mechanism 32. The guide rod is slidably inserted into the connecting plate 332. Through the opening of multiple locking slots 202, the locking pin 333 can be inserted into the corresponding locking slot 202 after the fixed ring 31 is rotated and adjusted, so as to achieve insertion and positioning with the inner cavity of the locking slot 202. Through the sliding insertion between the guide rod and the connecting plate 332, the sliding of the connecting plate 332 is limited, so that the sliding of the locking pin 333 and the pressing block 334 is more stable. By pressing the pressing block 334, the connecting plate 332 synchronously drives the movement of the locking pin 333, so as to lock and unlock the angle of the fixed ring 31 through the locking pin 333.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
