[0002] Stomatology, a medical discipline, primarily specializes in oral diseases, including oral and maxillofacial dermoids, submandibular space infections, maxillofacial lymphangiomas, odontoid malformations, mandibular retrusion, tetracycline-induced teeth, and leukoplakia of the tongue. During oral treatment, lighting is required to facilitate observation of the oral cavity and accurately perform treatment procedures. When performing an oral examination, the dentist requires the patient to open their mouth so that they can observe with a flashlight.

[0003] A Chinese patent discloses a dental auxiliary examination lighting device with the publication number CN216619530U. The patent discloses a dental auxiliary examination lighting device comprising a rubber clamp, the bottom end of which is threadedly connected to a threaded rod, the top end of which is fixedly connected to a lifting and rotating mechanism, the lifting and rotating mechanism comprising a bottom column fixedly connected to the top end of the rubber clamp, a first plug-in rod plugged into the side of the bottom column, and a sliding rod slidably plugged into the top end of the bottom column. The dental auxiliary examination lighting device can move two sets of lampshades and bulbs laterally through a lateral movement mechanism, and with the assistance of the inner wall of the lampshade and the reflector, more and more concentrated light from the bulb is refracted into the patient's oral cavity, thereby facilitating the doctor's observation of the patient's oral cavity. By setting up a lifting and rotating mechanism, the entire device can be lifted and rotated vertically, and the approximate height and direction of the bulb can be pre-adjusted according to the patient's height and body shape, and the operation is convenient and quick.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 5 As shown, a lighting auxiliary device for oral internal examination includes a fixed tube 1, the fixed tube 1 with a cavity inside is placed on the ground through a bottom plate 2 on the bottom surface, and a lifting assembly 3 installed inside the fixed tube 1 can drive the upper end of the support column 4 to rise and fall. The upper surface of the support column 4 is connected to the surface of the connecting block 401 by a fixed shaft 1 402 fixed inside the inner side of the connecting block 401, and a fixed shaft 2 501 is fixed inside the other end of the connecting rod 5 to rotate on the surface of the rotating member 6, and a connecting column 60 is fixed inside one end of the rotating member 6 with a cavity inside. 1. At the other end, the fixed tooth block 602 and the gear ring 603 are clamped with each other. The pressing piece 604 fixed on the surface of one side of the gear ring 603 can rotate the connecting plate 606 at the bottom to adjust the angle through the linkage rod 605 on the surface. The upper end of the bulb 7 is fixed with the clamping block 703 installed on the bottom of the connecting plate 606. The clamping plate 704 attached to the outside of the clamping block 703 is connected to the extrusion spring 705 fixed on the bottom of the connecting plate 606, and the limiting shaft 706 is rotated at the connection point of the two clamping plates 704 to limit them, so as to facilitate the rotation of the clamping block 703.

[0035] The lifting assembly 3 is provided with a knob 301 that rotates on the upper surface of the fixed cylinder 1. The knob 301 enables the screw 302 with inner thread connection to be raised and lowered. The movable plate 303 fixed at its bottom end slides on its surface under the limit of the limit rod 304 fixed on the inner side of the fixed cylinder 1.

[0036] Through the above technical solution, under the limitation of the limiting rod 304, the screw rod 302 can be limited by the movable plate 303 by rotating the knob 301, ensuring that the screw rod 302 can drive the upper support column 4 to move up and down.

[0037] A support spring 631 is fixed to the other side surface of the gear ring 603 , and a rotating ring 632 fixed at the other end of the support spring 631 rotates inside the rotating member 6 .

[0038] Through the above technical solution, under the support of the support spring 631, the gear ring 603 can be clamped on the surface of the gear block 602 when there is no external force driving, thereby limiting the rotation of the connecting plate 606.

[0039] The linkage rod 605 on the other side rotates on the surface of the limiting column 651 fixed on one side of the surface of the rotating member 6.

[0040] Through the above technical solution, under the setting of the limiting column 651, the linkage rod 605 on one side can be limited by the limiting column 651 on the other side when rotating, ensuring that the rotation of the lower connecting plate 606 is more stable.

[0041] The lampshade 701 arranged outside the bulb 7 slides on the bottom surface of the connecting plate 606 through a sliding member 702 fixed at the upper end.

[0042] Through the above technical solution, under the setting of the sliding member 702, the lampshade 701 can rotate around the bulb 7, so as to conveniently gather the light emitted by the bulb 7.

[0043] When in use, when the user uses the lighting auxiliary device for oral internal examination, the base plate 2 is placed on the ground, the entire device is supported by the fixed tube 1, and the knob 301 with a locking function latch structure is turned to enable it to be raised and lowered through the screw 302 connected by the inner thread. Under the limit of the movable plate 303 and the limit rod 304, the overall height of the device can be adjusted. The upper end connection block 401 is limited by the fixed axis 1 402, so that the connecting rod 5 can rotate around it, and the upper end of the rotating member 6 can rotate around the fixed axis 2 501, and the lower end is connected to the light bulb 7 through the connecting plate 606. By pressing the push piece 604, the tooth ring 603 is used to squeeze the support spring 631, so that the tooth ring 603 is disengaged from the tooth block 602, and the support spring 631 can be rotated under the connection of the rotating ring 632, so that the angle of the connecting plate 606 at the bottom can be adjusted arbitrarily, and then the sliding piece 702 is used to adjust the blocking angle of the lampshade 701 to make the lighting effect of the bulb 7 better. When the bulb 7 needs to be replaced, the bulb 7 is pulled downward so that the upper block 703 can squeeze the card plate 704 to both sides, so that the card plate 704 can rotate around the limit axis 706 with the assistance of the squeezing spring 705, which facilitates the disengagement of the bulb 7.

[0044] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.
