Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a lip and tooth protection device. Background Art

[0002] In various types of oral surgeries, such as oral endoscopic surgery, tongue surgery, tonsillectomy, adenoidectomy, vocal cord surgery, oral hard palate surgery, and esophagoscopy, it is routinely necessary to use an opener to open and fix the mouth, or to insert a direct laryngoscope into the mouth. Both the opener and the direct laryngoscope are made of steel. The opener needs to hook the upper and lower incisors, while the direct laryngoscope uses the upper incisors as a fulcrum. Both instruments can easily damage the upper incisors, causing them to wear, partially break, or even fall off. At the same time, due to the lack of protection for the lips, it is very easy to cause abrasions and pressure injuries to the upper lip during surgery, resulting in swelling and pain on the upper lip and mucosal ulcers after surgery. This not only affects the patient's recovery, increases the patient's injury and treatment time and cost, but is also more likely to cause patient dissatisfaction and disputes. Utility Model Content

[0018] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] REFERENCE Figure 1-3 A lip-tooth protection device, comprising a mouth guard 10 and a lip sleeve 20 connected to one side of the mouth guard 10; the mouth guard 10 and the lip sleeve 20 are integrally formed soft structure; wherein the mouth guard 10 is provided with a V-shaped groove 11 adapted to the incisors, and the lip sleeve 20 is provided with a 7-shaped groove 21 adapted to the lips, and the top of the connection between the lip sleeve 20 and the mouth guard 10 forms a tooth-lip-gum outer edge 30 adapted to the gum root and the lip-gum groove.

[0020] The mouthpiece 10 is the main component of the lip-teeth protector, which directly contacts the upper front teeth of the patient. The design of the mouthpiece 10 usually includes a V-shaped groove 11 that fits the front teeth, which ensures that the mouthpiece 10 fits the inside and outside of the teeth, while avoiding causing pressure damage to the teeth. The soft material of the mouthpiece 10 can provide cushioning and reduce potential damage to the teeth from surgical instruments. The width of the mouthpiece 10 is the width of four incisors, about 3 cm, and it extends beyond the gum margin on the inside of the front teeth, with a depth of about 1.3 cm in adults, and reaches the labial frenulum attachment on the outside of the front teeth.

[0021] The lip sleeve 20 is another part of the device, which is integrally formed with the mouthpiece 10 and connected to one side of the mouthpiece 10 by turning. The design of the lip sleeve 20 fits the lips, usually with a 7-shaped groove 21, which pushes the upper lip up to expose the teeth, while covering and protecting the upper lip of the patient from being scratched or bruised by the pressure or friction of the instruments during the operation.

[0022] The labial gingival outer edge 30 is located at the top of the connection between the lip sleeve 20 and the mouthpiece 10, which is designed to fit the gum root and labial gingival groove, providing additional protection for these sensitive areas. This design helps to avoid damage to the gum and labial gingival groove during the operation, while also providing better comfort. The width of the lip sleeve 20 is consistent with the width of the mouthpiece 10, and the height of the labial gingival outer edge 30 connected to the mouthpiece 10 reaches 2 / 3 of the depth of the gum root and labial gingival groove, with a depth of about 1.2 cm from the lower edge of the adult teeth to the turning line, and the area extending outward to the upper lip line.

[0023] During the operation, when the lip-teeth protector is correctly placed in the patient's mouth, the V-shaped groove 11 of the mouthpiece 10 will fit and fix on the upper front teeth, while the 7-shaped groove 21 of the lip sleeve 20 will push the upper lip up while covering and protecting the upper lip. The labial gingival outer edge 30 will fit the gum and labial gingival groove, providing protection for these areas. The soft structure of the entire device can absorb and distribute the force that may be exerted by the surgical instruments, thereby reducing the damage to the patient's lips and teeth. In addition, the integrally formed design ensures the stability of the device and the comfort of the patient, making the operation safer and more effective.

[0024] The cross-section of the combination of the mouthpiece 10 and the lip sleeve 20 is an inverted M shape. The inverted M-shaped cross-section design can more effectively distribute the force when the mouthpiece 10 and the lip sleeve 20 are subjected to pressure from surgical instruments, reducing the concentration of pressure on a single area, thereby protecting the teeth and lips from damage. It has good stability, and this structure makes the lip-teeth protector more stable in the mouth, less likely to shift during the operation. The inverted M-shaped cross-section design allows the force to be distributed to a wider area when the entire device is subjected to external force, reducing the local pressure on the teeth and lips.

[0025] The outlines of the dental brace 10, lip cover 20 and the outer edge of the teeth and labia-gingiva 30 have an arc-shaped transition design. During surgery, when the device is correctly placed in the patient's mouth, the arc-shaped design of the dental brace 10 will naturally fit the inside of the teeth without causing pressure or damage to them. The arc-shaped design of the lip cover 20 covers and protects the upper lip, and its arc-shaped transition ensures a close fit with the lips, while pushing the upper lip upward to prevent the mouth opener or laryngoscope from crushing the lips, avoiding damage caused by the pressure of the instrument. The arc-shaped design of the outer edge of the teeth and labia-gingiva 30 provides a gentle support for the gums and labia-gingival sulcus, protecting these areas from damage by surgical instruments.

[0026] The angle between the mouthpiece 10 and the lip guard 20 is 60-100 degrees. This design allows the lip guard 20 to form a specific angle when connected to the mouthpiece 10. This angle effectively pushes the upper lip upward to prevent it from being crushed by an opener or other medical device during surgery. This angle helps maintain a safe distance from the upper lip, reducing pressure and potential damage to the lip.

[0027] The dental braces 10, lip covers 20, and the outer edge of the teeth, lips, and gums 30 are provided with an antibacterial coating. Antibacterial coatings typically contain antibacterial agents, such as inorganic antibacterial materials such as silver, zinc, or copper, or organic antibacterial agents such as antibiotics, which can kill or inhibit the growth of bacteria through physical or chemical means. The antibacterial components in the coating can be continuously released or take effect upon contact with bacteria, effectively reducing bacterial colonization on the surface of medical devices, thereby reducing the risk of infection during surgery or treatment. In addition, some advanced antibacterial coatings also have self-healing capabilities and can self-repair after minor damage, maintaining the integrity and antibacterial properties of the coating.

[0028] The braces 10, lip covers 20 and the outer edge of the teeth, lips and gums 30 are fan-shaped designs that adapt to the incisors, lip contours, gum roots and labiogingival sulci. The fan-shaped design is a biomimetic design that imitates the natural form of teeth and gums. During surgery, when the lip and tooth protection device is placed in the patient's mouth, the fan-shaped design of the braces 10, lip covers 20 and the outer edge of the teeth, lips and gums 30 can fit closely to the patient's oral structure. This design enables the device to evenly disperse force, reduce pressure on specific areas, and thus reduce the risk of injury. At the same time, the fan-shaped design also contributes to the stability of the device in the mouth, ensuring that the device will not shift during surgery, providing a stable operating environment for surgery.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
