DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-4As shown, a device for assisting the molding of periodontal dressings after periodontal surgery includes a bite part and an extrusion plate 2, wherein the bite part is installed on the extrusion plate 2, and the extrusion plate 2 is placed between the teeth and the lips, so that the patient can bite the bite part through the teeth, and when the bite part bites, the extrusion plate 2 can be driven to translate toward the teeth or away from the teeth, and when the extrusion plate 2 moves away from the teeth, the lips can be pushed away from the teeth, thereby expanding the space between the lips and the teeth, and then the dressing can be conveniently applied to the periodontium. After coating, the extrusion plate 2 is driven to move toward the teeth, and the extrusion plate 2 can press and mold the dressing, and the bite part is composed of a movable plate 11 and a fixed plate 12, wherein the movable plate 11 is located above the fixed plate 12, and the movable plate 11 can move toward or away from the fixed plate 12, and the movable plate 11 and the fixed plate 12 are located between the upper teeth and the lower teeth, so that the movable plate 11 and the fixed plate 12 can be pressed and molded by the upper teeth and the lower teeth. For occlusion, a driving part is provided in the movable plate 11. When the movable plate 11 moves toward the fixed plate 12, the extrusion plate 2 can be conveniently driven to move away from the tooth portion. When the movable plate 11 moves away from the fixed plate 12, the extrusion plate 2 can be reset and move toward the tooth portion, so that the dressing can be easily pressed and formed. A dressing part is provided on the side of the extrusion plate 2 away from the occlusal part for temporarily storing the dressing. The dressing can be quickly shaped after encountering alcohol. When the movable plate 11 moves toward the fixed plate 12, the dressing in the dressing part can be squeezed into the oral cavity, so that the dressing can be conveniently applied to the periodontium. An alcohol storage part is provided on the side of the extrusion plate 2 close to the dressing part. Alcohol is stored in the alcohol storage part. When the movable plate 11 moves away from the fixed plate 12, the alcohol can be squeezed into the oral cavity, so that the dressing can be quickly shaped, thereby effectively improving the efficiency of dressing shaping.

[0024] like Figure 1-3As shown, the driving part includes a first slide groove 41 opened at one end of the moving plate 11 close to the extrusion plate 2, a first slider 42 is slidably connected in the first slide groove 41, a threaded groove 43 is opened at one end of the first slider 42 away from the extrusion plate 2, a threaded rod 44 is threadedly connected in the threaded groove 43, and the end of the threaded rod 44 away from the extrusion plate 2 extends to the end of the moving plate 11 away from the extrusion plate 2, a gear 46 is fixedly connected at one end of the threaded rod 44 away from the extrusion plate 2, a rack 45 is fixedly connected at one end of the fixed plate 12 away from the extrusion plate 2, and the rack 45 is meshed with the gear 46, a second slide groove 47 is opened in the extrusion plate 2, and a second slider 48 is slidably connected in the second slide groove 47 , and the first slider 42 is fixedly connected to the second slider 48. When the movable plate 11 moves toward the fixed plate 12, the gear 46 can move along the rack 45. At this time, the gear 46 can rotate. When the gear 46 rotates, it can drive the threaded rod 44 to rotate. Then the rotation of the threaded rod 44 can drive the first slider 42 to slide in the first slide groove 41 and away from the movable plate 11, so as to drive the extrusion plate 2 to move away from the tooth portion, thereby expanding the space between the lip and the tooth portion.

A one-way valve is installed on the tube 64, so that the dressing in the temporary storage box 61 can only be discharged outward and cannot be reversed. When the movable plate 11 moves toward the fixed plate 12, it can drive the second slider 48 to move downward. Then the movement of the second slider 48 can drive the first piston plate 62 to move downward through the L-shaped rod 63. Then the downward movement of the first piston plate 62 can squeeze the dressing in the temporary storage box 61. Under the action of squeezing, the dressing can be squeezed into the oral cavity through the connecting tube 64, so that the dressing in the temporary storage box 61 can be conveniently applied to the periodontium.

A third piston plate 73 is slidably connected in the alcohol box 71, and a one-way valve is installed on the third piston plate 73, so that the alcohol can only flow from bottom to top. A fixed pipe 74 is slidably connected in the second piston plate 72, and the top of the fixed pipe 74 extends to the top of the third piston plate 73. A positioning rod 75 is slidably connected in the third piston plate 73, and the top of the positioning rod 75 is The end is fixedly connected to the inner top wall of the alcohol box 71, the bottom end of the positioning rod 75 is fixedly connected to the limiting plate 76, and the limiting plate 76 is in contact with the third piston plate 73, the second piston plate 72 is fixedly connected with a connecting rod 77, and the top end of the connecting rod 77 passes through the third piston plate 73 and the alcohol box 71 and is fixedly connected to the L-shaped rod 63, the third piston plate 73 is provided with a connecting portion, when the connecting rod 77 moves upward, it can drive the third piston plate 73 to move upward, the top end of the alcohol box 71 is fixedly connected with a connecting pipe, and the other end of the connecting pipe is fixedly connected with the connecting pipe 64; The connecting part includes a first magnetic member 78 embedded on the third piston plate 73, and a second magnetic member 79 is fixedly connected to the surface of the connecting rod 77, and the ends of the first magnetic member 78 and the second magnetic member 79 close to each other have different magnetic poles, and the first magnetic member 78 and the second magnetic member 79 are both magnets; When the L-shaped rod 63 moves downward, it can push the second piston plate 72 downward through the connecting rod 77, and the second piston plate 72 will squeeze the alcohol. At this time, the alcohol can flow to the top of the third piston plate 73 through the fixed tube 74. At the same time, the first magnetic part 78 and the second magnetic part 79 will be adsorbed together under the action of magnetism. When the movable plate 11 moves away from the fixed plate 12, the L-shaped rod 63 will move upward, and then the upward movement of the L-shaped rod 63 will drive the connecting rod 77 to move upward. Then the connecting rod 77 can drive the third piston plate 73 to move upward under the action of the first magnetic part 78 and the second magnetic part 79. At this time, the alcohol will be squeezed into the connecting tube, and then flow into the connecting tube 64 through the connecting tube, and finally flow into the dressing through the connecting tube 64, so that the alcohol in the alcohol box 71 can be squeezed into the oral cavity through the occlusion of the patient's teeth, and then the dressing can be quickly shaped.

[0028] like Figure 1 and Figure 2 As shown, an elastic reset member 8 is provided between the movable plate 11 and the fixed plate 12 . The elastic reset member 8 is a compression spring. When the movable plate 11 moves toward the fixed plate 12 , the movable plate 11 can be reset more conveniently, thereby moving the movable plate 11 away from the fixed plate 12 .

[0029] like Figure 1 and Figure 2 As shown, the side surfaces of the movable plate 11 and the fixed plate 12 that are away from each other are fixedly connected with positioning blocks 9, and the teeth are placed in the positioning blocks 9 to limit the movable plate 11 and the fixed plate 12 to prevent the movable plate 11 and the fixed plate 12 from sliding off the teeth.

[0030] Working principle: The movable plate 11 and the fixed plate 12 are placed between the upper teeth and the lower teeth. When the patient bites, the movable plate 11 can move toward the fixed plate 12, thereby driving the extrusion plate 2 to move away from the tooth portion, thereby expanding the space between the lip and the tooth portion. At the same time, when the movable plate 11 moves toward the fixed plate 12, the dressing in the dressing portion can be coated on the periodontium. After coating, under the action of the elastic reset member 8, the movable plate 11 can move away from the fixed plate 12, thereby driving the extrusion plate 2 to move toward the tooth portion, thereby pressing and forming the dressing. At the same time, when the movable plate 11 moves away from the fixed plate 12, the alcohol in the alcohol storage portion can be squeezed into the oral cavity and flow onto the dressing, thereby enabling the dressing to be quickly shaped. In summary, the patient can complete operations such as dressing and applying alcohol only through the action of tooth occlusion, thereby effectively improving the efficiency of periodontal dressing.
