[0033] Now, the present invention will be further described in detail with reference to the accompanying drawings.

[0034] In medical operations after general anesthesia, tracheal intubation is an important step in maintaining the patient's respiratory tract. However, this process is often accompanied by the risk of tooth injury or loss. Since the patient cannot actively cooperate under anesthesia, when medical staff insert a laryngoscope or catheter, the teeth may become loose or even fall out due to direct contact between the instrument and the teeth or improper control of the operating force. Especially for patients with periodontal diseases, fragile teeth or irregular tooth alignment, such risks are significantly increased. To address this problem, various tooth protection devices have been developed in the prior art, and their design goals all revolve around reducing the impact of external forces on the teeth, dispersing the pressure distribution, and providing physical isolation protection.

[0035] Currently, common tooth protection devices are mainly divided into three major types: dental pad type, mouthguard type, and dental floss fixation type. Dental pad products are mostly made of silicone or thermoplastic plastics, and their shapes are mostly arc-shaped strip structures. They form a buffer layer by clamping between the upper and lower dental arches, such as disposable medical dental pads. The advantage of such products is that the materials are soft and the cost is low. However, their fixing effect depends on the occlusion state of the patient's dental arch, and it is easy to shift under the condition of muscle relaxation after anesthesia, resulting in a weakened protection effect. In addition, the thickness of the dental pad may affect the operating space for inserting the laryngoscope, and some models may block the view due to their large volume, increasing the difficulty of intubation.

[0036] Mouthguard-like devices draw on the design concepts of sports protective equipment. They are usually made by molding processes, can cover the outer surfaces of single or double dental arches, and are fixed to the head by elastic bands or fasteners. Such products perform well in terms of contact area and pressure dispersion, but their overall volume is relatively large, which may interfere with the flexible operation of intraoral instruments, and the wearing process is relatively cumbersome, limiting their practicality in emergency intubation scenarios. In recent years, some improved mouthguards have attempted to use memory foam or gel linings to enhance comfort, but their deformation recovery ability after high-temperature disinfection still needs to be verified.

[0037] Dental floss fixation devices, as another technical route, focus on the targeted protection of individual teeth or specific tooth positions. Traditional dental floss sleeves are usually woven from polymer materials into a ring structure and sleeved between adjacent teeth to enhance stability. For example, some models are made of polyethylene monofilaments to form a mesh sleeve body, and multiple-point fixation is achieved through cross-winding. Such designs have a certain effect in dispersing lateral forces, but their wire diameters are usually relatively thin, and long-term use may cause cutting damage to the gums. In addition, the selection of the elastic modulus of existing dental floss sleeves often fails to fully consider the adaptability to different crown morphologies, resulting in uneven pressure distribution and possible local stress concentration during dynamic operations, which instead increases the probability of root damage.

[0038] In terms of materials science, existing technologies mostly use silicone rubber, polyurethane or latex as the main materials. Although these materials have biocompatibility, they still have limitations in practical applications. For example, latex materials may cause allergic reactions, and silicone rubber is prone to permanent deformation after repeated stretching, affecting the sealing performance. In recent years, some studies have attempted to introduce nanocomposites to improve wear resistance and elastic recovery rate, but the clinical verification data of related products are not yet sufficient. In addition, some products have anti-slip textures added to their surfaces to enhance the fixation effect, but overly rough surface treatment may exacerbate mucosal abrasion.

[0039] In terms of structural design, the innovations of existing devices mostly focus on the optimization of geometric forms. For example, the Y-shaped bifurcated dental floss sleeve recorded in a patent document improves the fixation stability by increasing the number of fulcrums, but its complex weaving structure increases the cleaning difficulty and there is a risk of easy breakage at the crossing of the wires. Another design uses a variable-diameter elastic ring structure to adapt to different tooth gaps by adjusting the diameter of the ring body, but auxiliary tools are still required for installation in actual use, and the operation convenience is insufficient. It is worth noting that there is a relative lack of special designs for the protection of molars in existing technologies, and the teeth in this area are more vulnerable to indirect damage by the lever action of instruments during intubation due to their relatively deep anatomical positions.

[0040] From the analysis of clinical application scenarios, there are still obvious short - comings in the applicability of existing tooth protection devices in emergency or rapid sequential intubation. Most products need to be pre - adjusted according to the patient's oral conditions, but the relaxation of the mandibular facial muscles in the anesthetized state may change the relative position of the dentition, resulting in the ineffective fitting of the pre - set device. In addition, the existing dental floss sleeves lack coordinated design with intubation instruments. For example, the friction coefficient matching problem of the contact surface between the laryngoscope blade and the dental floss sleeve is not considered, which may increase the operating resistance. In the pediatric field, due to the large differences in the crown morphology of children and lower cooperation, the scaled - down versions of existing adult - sized products are often difficult to achieve effective fixation.

[0041] In terms of manufacturing processes, injection molding is still the mainstream technology. However, for dental floss sleeves with complex internal structures, it is difficult for traditional molds to achieve high - precision micro - structure processing. Although 3D printing technology has emerged in recent years and can achieve personalized customization, the material strength and sterilization tolerance still need to be further verified. Some high - end products attempt to integrate pressure - sensing elements to monitor the tooth force in real - time, but the introduction of such electronic components significantly increases the cost and there is a risk of circuit failure due to body fluid penetration.

[0042] Please refer to Figure 1-7 As shown, in this embodiment, a tooth - shedding - prevention dental floss sleeve is provided, including: a fixed box 1 and a number of dental flosses 4. One side of the fixed box 1 is provided with a threading groove 2, and the other side is provided with a clamping member. The threading groove 2 vertically penetrates the fixed box 1, and the dental floss 4 vertically penetrates the threading groove 2. One side of the fixed box 1 is provided with an information pasting area;

[0043] An L - shaped baffle 5 corresponding to the threading groove 2 elastically slides on one side and the lower side of the fixed box 1. A plurality of limiting grooves 6 are provided on the lower side of the L - shaped baffle 5, and the plurality of limiting grooves 6 are horizontally equidistantly distributed. The limiting grooves 6 communicate with the threading groove 2, and the width of the limiting grooves 6 is equal to the diameter of the dental floss 4. The lower end of the dental floss 4 penetrates the corresponding limiting groove 6. A push block 7 is installed on one side of the L - shaped baffle 5, and a lock box 9 is installed on the adjacent side. A lock shell 8 adapted to the lock box 9 is installed on one side of the fixed box 1. The lock box 9 is clamped in the lock shell 8. Elastic clamping components are elastically fitted on the upper and lower sides of the inner wall of the lock box 9. Card slots are provided on the upper and lower sides of the inner wall of the lock shell 8. One end of the clamping component is clamped in the card slot and the other end penetrates to the outside of the push block 7. A shearing component is elastically fitted in the fixed box 1 and two elastic components are provided. The shearing component is located between the upper and lower two elastic components. A pressing plate 21 is installed on one side of the shearing component. The elastic components are located on one side of the pressing plate 21. A rotating member is movably fitted on the pressing plate 21. Two blocking members are rotatably fitted on one side of the fixed box 1. The rotating member is located between the upper and lower two blocking members. The blocking members correspond to the rotating member and the elastic components;

[0044] Multiple arc-shaped spring pieces 3 are installed on both sides of the threading slot 2, and the multiple arc-shaped spring pieces 3 are vertically equidistantly distributed. The arc-shaped spring pieces 3 are located at the opening of the threading slot 2. The dental floss 4 is divided into multiple colors. Different colors of dental floss 4 are used to distinguish according to the looseness of the patient's teeth.

[0045] The application of one aspect of this embodiment is as follows: when in use, according to the looseness and number of the patient's teeth, select the dental floss 4 of the required color and tie it tightly on the patient's teeth, then squeeze the two clamping components on the push block 7 to move closer to each other, so that the part of the clamping component located in the clamping slot is disengaged, and the limit of the lock shell 8 on the lock box 9 is cancelled, and then the push block 7 is moved to make the L-shaped baffle 5 translate to expose the openings on the side and bottom of the threading slot 2, and then first put the dental floss 4 into the threading slot 2 in turn, and then clamp the tail of the dental floss 4 into the limit slot 6 in turn. When all are put in, release the push block 7, and the push block 7 rebounds quickly under the action of elastic force. During the rebound process, the clamping component is squeezed by the lock shell 8 to slide inwardly of the lock box 9. When the clamping component slides to be flush with the slot, the clamping component is clamped by the elastic force. It rebounds quickly and re-engages in the slot, completing the blocking of the threading slot 2. Finally, knot the ends of a single or multiple dental flosses 4 in sequence, so that the L-shaped baffle 5 uses the limit slot 6 to intercept the knot, and then use the clamp to clamp the fixing box 1 on the patient's clothes. When the dental floss 4 needs to be removed, pull the rotating member so that one end of it engages with the two blocking members, and then rotate the rotating member to drive the two blocking members to rotate at the same time, so that the blocking member cancels the limit on the elastic component, thereby releasing the limit on the pressing plate 21, and then squeeze the pressing plate 21 to insert the shearing component into the threading slot 2 to cut all the dental floss 4, so that the tail section of the dental floss 4 can be pulled out through the knot, and the other section of the dental floss 4 can be pulled out from the top of the fixing box 1. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0046] The threading groove 2 facilitates the unified collection of multiple dental flosses 4, and the L-shaped baffle plate 5 is used to block and limit the dental floss 4 in the threading groove 2, thereby improving the fixing efficiency and overall neatness of the dental floss 4. The limiting groove 6 facilitates the positioning of the rope knot, thereby reducing the probability of the dental floss 4 slipping out of the threading groove 2 due to accidental touch. The clamping member facilitates the clamping of the fixing box 1 on the patient's clothes, thereby improving the convenience of using the dental floss set. By pressing the pressing plate 21, the shearing assembly is conveniently pressed into the threading groove 2 to cut the dental floss 4, thereby improving the convenience of removing the dental floss 4 and reducing the contact between the part stained with the patient's saliva and the fixing box 1 caused by pulling the dental floss 4. The elastic member facilitates the shearing assembly to quickly rebound and reset after being compressed by the elastic force. The rotating member cooperates with the blocking member to facilitate the limiting of the sliding of the shearing assembly. The main part of the dental floss set can be reused through this device, and only the dental floss 4 needs to be replaced, thereby reducing the cost of consumables of the dental floss set.

[0047] likeFigure 1 , 4 As shown, the clamping assembly of this embodiment includes a clamping block 11, and the vertical section of the clamping block 11 is a right-angled triangle structure. The two clamping blocks 11 respectively penetrate the upper and lower sides of the lock box 9, and the clamping block 11 is clamped in the clamping groove. The two clamping blocks 11 are respectively provided with L-shaped connecting plates 12 on the inner sides thereof. One side of the L-shaped connecting plate 12 is slidably fitted in the lock box 9, and the other side is slidably fitted in the L-shaped baffle plate 5 and the push block 7. The two L-shaped connecting plates 12 are respectively provided with pressing blocks 14 on the outer sides thereof. The two pressing blocks 14 respectively penetrate the upper and lower sides of the push block 7. A fixing plate 10 is provided between the two sides of the inner wall of the lock box 9, and the L-shaped connecting plate 12 and the fixing plate 10 are provided between them. A spring 15 is installed, and the block 11 cooperates with the card slot to facilitate limiting the L-shaped baffle 5, so that the dental floss 4 is limited in the limiting slot 6. By squeezing the two pressing blocks 14 close to each other, the block 11 can be separated from the card slot, and the limitation of the L-shaped baffle 5 is released, so that the L-shaped baffle 5 is conveniently moved to release the obstruction of the threading slot 2, and then the dental floss 4 is conveniently placed in the threading slot 2 and the limiting slot 6. When the block 11 is aligned with the card slot through the spring 15, the spring 15 rebounds and pushes the L-shaped connecting plate 12 away from the fixing plate 10, so that the block 11 is quickly connected to the card slot, thereby improving the convenience of fixing the L-shaped baffle 5.

The second fixing plates 19 are installed on one side of the fixing box 1. A cross bar is installed between the two second fixing plates 19. Two rotating rings are installed on one side of the clamping plate 20. The rotating rings are rotationally fitted around the circumference of the cross bar. A torsion spring corresponding to the fixing box 1 and the clamping plate 20 is sleeved on the circumference of the cross bar. The torsion spring is located between the two rotating rings. Through the cooperation of the second fixing plates 19, the cross bar and the rotating rings, it is convenient to provide a fulcrum for the rotation of the clamping plate 20. Through the torsion spring, a torque is generated between the clamping plate 20 and the fixing box 1, which facilitates the fixing box 1 to tightly clamp on the patient's clothes by using the clamping plate 20.
