Description

Technical Field

[0001] The utility model relates to the technical field of inspection devices, in particular to a special oral inspection device. Background Art

[0002] As is well known, the oral cavity is an important part of the human body's digestive and speech functions, consisting of the intraoral and extraoral parts. The intraoral part includes tissues such as teeth, tongue, cheeks, lips, and gums, and through these tissues, functions such as chewing, swallowing, and speech expression are coordinated. The extraoral part includes the skeletal structure and soft tissues of the maxillofacial region, which are closely related to facial expressions, chewing movements, etc. The oral cavity is not only the starting point of the digestive system but also plays a key role in language communication and facial expression. Maintaining oral health is crucial for overall health. Usually, an oral speculum is needed during oral examinations. An oral speculum is an auxiliary tool used by dentists during dental examinations and treatments. It can open the patient's mouth to facilitate the doctor's clearer observation of the internal conditions of the oral cavity, such as teeth, gums, tongue, etc.

[0003] However, for traditional special oral inspection devices, usually medical staff need to continuously apply force to hold the oral speculum against the oral cavity, which may cause a sense of fatigue in the hands and arms, especially during long surgeries or treatments. Therefore, there is an urgent need for technological improvement. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and an oral special inspection device is proposed. When the oral special inspection device is used, by pressing the two ends of the clamping block against the upper and lower ends inside the oral cavity, while rotating the first knob to drive the bidirectional threaded rod to rotate, the threaded sleeve block is driven to rotate. The threaded sleeve block is limited by the limiting block sliding in the limiting groove, and then the two ends of the clamping block move towards each other, and the distance between the clamping blocks can be adjusted according to the need, so as to adjust the opening degree of the mouth. Medical staff do not need to continuously apply force for a long time, thereby reducing the sense of fatigue in the hands and arms and improving the comfort and efficiency of the operation.

[0012] Through the above technical solution, it is convenient to improve the cooperation through the limiting grooves and the limiting blocks.

[0013] Furthermore, the limiting blocks are respectively slidably connected inside the limiting grooves.

[0014] Through the above technical solution, by the limiting blocks being respectively slidably connected inside the limiting grooves, it is convenient to limit the threaded sleeve block to move in the opposite direction.

[0015] Furthermore, in the middle of the inner walls of the front end and the rear end of the limiting groove, sliding grooves are opened. On both sides of the inner walls of the sliding grooves, a plurality of rollers are rotatably connected. The outer walls of the adjacent sides of the rollers are closely attached to the outer walls of both ends of the limiting block.

[0016] Through the above technical solution, it is convenient to reduce the friction when the threaded sleeve block moves through the rollers.

[0017] Furthermore, on both sides of the outer wall of the rear end of the installation box, grip blocks are fixedly connected.

[0018] Through the above technical solution, it is convenient to hold the whole through the grip blocks.

[0019] Furthermore, the worm meshes with the worm wheel.

[0020] Through the above technical solution, by the worm meshing with the worm wheel, it is convenient to drive the worm wheel to rotate along with the rotation of the worm.

[0021] Further, the upper end of the worm penetrates through the storage box to the outside of the storage box and is fixedly connected with a second knob.

[0034] Refer to Figures 1-5 , an embodiment provided by the present invention:

[0035] A special oral inspection device includes an installation box 1. Storage grooves 2 are provided on both the upper and lower parts of the front outer wall of the installation box 1. The middle of the bottom surface of the lower storage groove 2 is rotatably connected to a bidirectional threaded rod 3. Threaded sleeve blocks 4 are sleeved on both the upper and lower parts of the rod body of the bidirectional threaded rod 3. The middle parts of the front outer walls of the threaded sleeve blocks 4 are fixedly connected to clamping blocks 5;

[0036] The middle part of one outer wall of the installation box 1 is fixedly connected to a storage box 12. A storage cavity 13 is provided inside the storage box 12.

The middle of the rear end of the inner bottom surface of the storage cavity 13 is rotatably connected to a worm 17.

[0037] Compared with the existing special oral inspection device, when this special oral inspection device is used, by rotating the second knob 18, the worm 17 is driven to rotate. Through the meshing of the worm 17 and the worm gear 15, the worm gear 15 and the rotating rod 14 are driven to rotate. By rotating the rotating rod 14, the irradiation lamp 16 is driven to adjust the angle, and the angle adjustment of the irradiation lamp 16 can be realized, ensuring the accurate inspection and irradiation angle of the irradiation lamp 16 on the oral cavity, and the practical performance is relatively high.

[0038] The bidirectional threaded rod 3 passes through the storage groove 2 to the upper end outside the installation box 1 and is fixedly connected with a first knob 6. By means of the first knob 6, it is convenient to drive the bidirectional threaded rod 3 to rotate. Limiting grooves 8 are opened on both sides of the inner wall of the storage groove 2. Limiting blocks 7 are fixedly connected to both sides of the outer wall of the clamping block 5. Through the limiting grooves 8 and the limiting blocks 7, it is convenient to improve the cooperation. The limiting blocks 7 are respectively slidably connected inside the limiting grooves 8. By the limiting blocks 7 being respectively slidably connected inside the limiting grooves 8, it is convenient to limit the threaded sleeve block 4 to move in opposite directions. The middle parts of the front and rear inner walls of the limiting groove 8 are respectively provided with sliding grooves 9. A plurality of rollers 10 are rotatably connected to both inner walls on both sides of the sliding groove 9.

By means of the rollers 10, it is convenient to reduce the friction when the threaded sleeve block 4 moves. Holding blocks 11 are fixedly connected to both sides of the outer wall of the installation box 1. By means of the holding blocks 11, it is convenient to hold the whole. The worm 17 and the worm gear 15 are meshed with each other. By the worm 17 and the worm gear 15 being meshed with each other, it is convenient to drive the worm gear 15 to rotate as the worm 17 rotates. The upper end of the worm 17 passes through the storage box 12 to the outside of the storage box 12 and is fixedly connected with a second knob 18. By means of the second knob 18, it is convenient to drive the worm 17 to rotate.

[0039] Working principle: When in use, by pressing the two ends of the clamping block 5 against the upper and lower ends in the oral cavity, while rotating the first knob 6 to drive the bidirectional threaded rod 3 to rotate, the threaded sleeve block 4 is driven to rotate. The threaded sleeve block 4 is limited by the limiting block 7 sliding in the limiting groove 8, so that the two clamping blocks 5 move in opposite directions, and the distance between the clamping blocks 5 can be adjusted as required, thereby adjusting the opening degree of the mouth. Medical staff do not need to continuously apply force for a long time, thus reducing the fatigue of the hands and arms and improving the comfort and efficiency of the operation. By rotating the second knob 18, the worm 17 is driven to rotate. By the worm 17 and the worm gear 15 being meshed with each other, the worm gear 15 and the rotating rod 14 are driven to rotate. By the rotation of the rotating rod 14, the irradiation lamp 16 is driven to adjust the angle, and the angle adjustment of the irradiation lamp 16 can be realized to ensure the accurate inspection and irradiation angle of the irradiation lamp 16 on the internal part of the oral cavity.
