For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: like Figure 1 and Figure 2 As shown, a frenulum surgical retractor with illumination and traction functions includes a support ring 1. The top of the support ring 1 rests against the patient's upper lip, and the bottom of the support ring 1 rests against the patient's lower lip, thereby opening the patient's mouth. Two pairs of intraoral alveolar supports 14 are symmetrically arranged on both sides of the side of the support ring 1 facing the patient's oral cavity. The intraoral alveolar supports 14 are used to rest against the patient's alveoli, facilitating mouth opening. Two pairs of extraoral alveolar supports 15 are symmetrically arranged on both sides of the side of the support ring 1 facing the patient's oral cavity. The extraoral alveolar supports 15 are used for pressing, causing the angle between the upper and lower parts of the support ring 1 to change, allowing the patient's mouth to be opened at different angles according to surgical needs. Each pair of intraoral alveolar supports 14 and extraoral alveolar supports 15 are arranged longitudinally, with the upper intraoral and extraoral supports 14 and 15 tilted upwards, and the lower ones tilted downwards. This structure facilitates the support of the intraoral supports 14 on the patient's upper and lower teeth, allowing the patient's mouth to open stably and preventing muscle fatigue and shaking caused by prolonged lack of support. A traction hook 3 is installed at the top of the support ring 1 for easy traction of the frenulum or lingual frenulum. A lighting lamp 2 is installed at the bottom of the support ring 1, with its light-emitting end tilted towards the patient's mouth to illuminate the inside of the mouth, thus assisting the surgical staff.

[0022] like Figure 2As shown, the support ring 1 has connecting blocks 10 on both the top and bottom inner sides. The connecting block 10 at the top of the support ring 1 has a first fixing plate 11, which is used to install the traction hook 3. The connecting block 10 at the bottom of the support ring 1 is connected to a second fixing plate 16, which is used to install the lighting lamp 2. The first fixing plate 11 and the second fixing plate 16 are inclined outwards. The first fixing plate 11 and the second fixing plate 16 are made of malleable material. According to the usage requirements, the first fixing plate 11 and the second fixing plate 16 can be bent and deformed by external force, so that the tilt angle of the first fixing plate 11 and the second fixing plate 16 changes, thereby facilitating medical personnel to perform surgery better. The connecting blocks 10 facilitate the support connection of the first fixing plate 11 and the second fixing plate 16. The bottom end of the first fixing plate 11 has a sleeve joint 12, and the middle of the sleeve joint 12 has a sleeve hole 121. The sleeve joint 12 and the sleeve hole 121 facilitate the installation of the traction hook 3 and the adjustment and use of the traction hook 3. The side of the connector 12 is aligned with the connector hole 121 and has a clamping knob 122, which facilitates fixing the position of the pull hook 3. The top of the second fixing plate 16 has a mounting platform 17, and the mounting platform 17 has a threaded groove 18 in the middle. The cooperation between the mounting platform 17 and the mounting groove facilitates the installation of the lighting lamp 2 and its use. The support ring 1 has symmetrical support rods 13 on both sides. The support ring 1 is divided into upper and lower parts from the middle of the support rods 13 on both sides. This structure facilitates the tilt angle adjustment of the upper and lower parts of the support ring 1. The upper and lower parts of the support ring 1 are provided with transition parts 19 at the joint position. The transition parts 19 of the upper and lower parts of the support ring 1 are rotatably connected, which facilitates the adjustment of the tilt angle of the support ring 1, thereby facilitating the unfolding of the intraoral alveolar support 14 and forcing the patient's mouth to open. Positioning knobs 191 are provided on both sides of the lower part of the support ring 1, aligned with the transition parts 19. Twisting the positioning knobs 191 forces the transition parts 19 of the upper and lower parts of the support ring 1 to press against each other. This increased friction after pressing against each other fixes the angle between the upper and lower parts of the support ring 1, facilitating adjustment and fixation according to usage requirements. Both the intraoral alveolar support 14 and the extraoral alveolar support 15 are mounted on the support rod 13. A silicone cylinder 141 is provided at the end of both the intraoral alveolar support 14 and the extraoral alveolar support 15 away from the support rod 13. The silicone cylinder 141 is used to engage with the patient's teeth.

[0023] like Figure 3As shown, the lighting lamp 2 has a mounting connector 21 at its bottom, with a stud 22 in the middle of the mounting connector 21. The stud 22 connects to the threaded groove 18, facilitating the connection between the lighting lamp 2 and the second fixing plate 16, and also allowing for flexible assembly and disassembly of the lighting lamp 2 according to usage requirements. The back of the lighting lamp 2 has a battery mounting part 23, inside which is a button battery. The end of the button battery has an insulating sheet 24, which is detachably connected to the battery mounting part 23. Removing the insulating sheet 24 powers the lighting lamp 2; inserting the insulating sheet 24 de-energizes the lighting lamp 2, preventing the button battery from powering it and causing the lighting lamp 2 to stop illuminating. The button battery has a capacity of 220mAh, providing continuous power for ≥4 hours (meeting the needs of a single surgery), and an operating voltage of 3V. The inner side of the battery mounting part 23 has a battery compartment, which is an injection-molded plastic shell (made of ABS medical plastic) embedded inside the lighting lamp 2. The top has a snap-on battery compartment cover with anti-slip textured edges for easy battery replacement. Two metal contacts (a gold-plated copper contact for the positive terminal and a nickel-plated iron contact for the negative terminal) are located at the bottom of the battery compartment, corresponding to the positive and negative terminals of the battery, respectively. The ends of the contacts are soldered to the wires. The connection points between the wires and the light-emitting components inside the lighting lamp 2 and the battery compartment are all fixed with solder and insulated with heat-shrink tubing (0.8mm in diameter). Medical-grade sealant is applied to both ends of the heat-shrink tubing. The insulating sheet 24 is a polyester film sheet, with one end inserted between the positive terminal of the battery and the positive contact of the battery compartment (blocking the circuit), and the other end extending to the outside of the battery compartment, with a semi-circular pull ring at the end. In use, the operator pulls the ring to remove the insulating sheet 24, and the positive terminal of the battery contacts the contact, completing the circuit; when not in use, the insulating sheet 24 remains inserted to prevent battery leakage and loss.

[0024] like Figure 4 As shown, the top of the traction hook 3 is provided with an adjusting rod 31. The adjusting rod 31 is inserted into the inner side of the socket hole 121. The pressing knob 122 is used to press against the adjusting rod 31 to fix the position of the adjusting rod 31, so that the traction hook 3 can pull and fix the frenulum of the labia or tongue, thereby facilitating the assistance of medical personnel in performing surgery.

[0025] like Figure 1 As shown, the support ring 1, traction hook 3, and lighting lamp 2 are single-use products and are discarded after use. The support ring 1, traction hook 3, and lighting lamp 2 are detachably connected, facilitating position adjustment of the traction hook 3 and lighting lamp 2. The support ring 1 has a C-shaped cross-section and is made of resilient plastic. The outer surface of the support ring 1 is covered with a medical-grade silicone layer with a thickness of 0.5-1mm to improve oral contact comfort.

[0026] Working principle: In use, the support ring 1 serves as the core carrier. The top of the support ring 1 rests against the patient's upper lip, and the bottom rests against the lower lip. Two pairs of longitudinal intraoral alveolar supports 14, symmetrically arranged on both sides, can be correspondingly engaged in the patient's upper and lower alveoli. Then, medical staff press the two upper and lower aligned extraoral pressure brackets 15, forcing a change in the angle between the upper and lower parts of the support ring 1, causing the intraoral pressure brackets 14 to open the patient's mouth. After the patient's mouth is opened to the appropriate position, the positioning knob 191 is tightened, thereby achieving the purpose of fixing the angle between the upper and lower parts of the support ring 1. Through the supporting force of the support ring 1 and the fixing effect of the intraoral alveolar supports 14, the patient's mouth is stably opened, avoiding mouth muscle fatigue and shaking caused by prolonged lack of support. The top of the support ring 1 is connected to the first fixing plate 11 through the connecting block 10. The sleeve 12 at the bottom of the first fixing plate 11 has a sleeve hole 121, into which the adjusting rod 31 of the traction hook 3 can be inserted. With the help of the clamping knob 12 on the side of the sleeve 12, the patient can achieve a stable opening of the mouth. 2. Tighten the adjusting rod 31 to fix the position of the traction hook 3, thereby effectively pulling and fixing the patient's labial or lingual frenulum; the bottom of the support ring 1 is connected to the second fixing plate 16 through the connecting block 10. The threaded groove 18 of the mounting platform 17 at the top of the second fixing plate 16 cooperates with the stud 22 of the mounting connector 21 at the bottom of the lighting lamp 2, so that the lighting lamp 2 can be detachably installed. After removing the insulating sheet 24 of the button battery in the battery mounting part 23 of the lighting lamp 2, the button battery powers the lighting lamp 2, and its light-emitting end is tilted towards the inside of the patient's oral cavity to provide sufficient lighting for the surgical operation; at the same time, the support ring 1, the traction hook 3 and the lighting lamp 2 are all disposable products, and the three are detachably connected. The position of the traction hook 3 and the lighting lamp 2 can be adjusted according to actual needs before the operation. In addition, the medical silicone layer wrapped around the outside of the support ring 1 can improve the patient's oral cavity contact comfort. The components work together to provide stable mouth opening support, precise tissue traction and clear visual illumination for medical personnel to perform labial and lingual frenulum surgery, and assist the smooth operation.

[0027] In summary, compared with the prior art, this application provides an intraoral alveolar support 14 on the side of the support ring 1 facing the oral cavity. The intraoral alveolar support 14 can be secured to the patient's teeth, thereby providing support for the patient's teeth and preventing mouth muscle fatigue and shaking after prolonged mouth opening. Simultaneously, the top of the support ring 1 is equipped with a traction hook 3, which can be used to pull the patient's labial or lingual frenulum, facilitating surgery for medical personnel. The bottom of the support ring 1 is equipped with a lighting lamp 2, which can illuminate the patient's oral cavity, thus assisting medical personnel in performing surgery.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
