The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] In one embodiment of the present application, a ring-shaped forming sheet structure 100 is provided. Figures 1 to 5 This annular shaping sheet structure 100 can make the shaping sheet 30 surround the annular body 31, so that the annular body 31 can be sleeved on the user's teeth for use, and the size of the annular body 31 can be adjusted by the adjustment tool 200, so that the annular body 31 can fit the circumference of the teeth and better fit the teeth, thereby better repairing the user's teeth. Figure 7 The adjusting tool 200 may be a screwdriver, which is connected to the rotating member 20 through the screwdriver bit 220 to drive the rotating member 20 to rotate around the axis c relative to the shell 10, so that the two connecting parts 33 of the forming sheet 30 can be gradually stacked and wound around the outer periphery of the winding part 22, thereby adjusting the size of the annular body 31.

[0039] In some embodiments, see Figure 1 and Figure 2 The annular shaping sheet structure 100 includes a housing 10, a rotating member 20 and a shaping sheet 30. The housing 10 is used to be sleeved on the outer periphery of the rotating member 20 so that the rotating member 20 can rotate relative to the housing 10 around the axis c. The shaping sheet 30 is used to form an annular body 31 to sleeve the user's teeth. The rotating member 20 is used to connect the two ends 32 of the shaping sheet 30. When the rotating member 20 rotates relative to the housing 10 around the axis c, the two connecting parts 33 of the shaping sheet 30 are gradually stacked and wound around the outer periphery of the rotating member 20, thereby reducing the size of the annular body 31.

[0040] In some embodiments, see Figure 2 and 3 One end of the forming sheet 30 is bent toward the other end of the forming sheet 30 to form an annular body 31. The annular body 31 is connected to the two end portions 32 of the forming sheet 30 through two connecting portions 33. The annular body 31 is located outside the shell 10 so that the annular body 31 can fit over the user's teeth.

[0041] In some embodiments, see Figure 2 , Figure 4 and Figure 5The housing 10 has a through hole 12 and a side wall 11. The through hole 12 extends along a first direction a and is arranged to penetrate the housing 10 in parallel with the first direction a. The side wall 11 is provided with a notch 111. The notch 111 penetrates part of the side wall 11 along a second direction b, so that part of the through hole 12 can communicate with the outside through the notch 111 along the second direction b. The first direction a is perpendicular to the second direction b, the first direction a is parallel to the axis c, and the second direction b is perpendicular to the axis c.

[0042] In some embodiments, the notch 111 has a certain length in the first direction a, and the length of the notch 111 is greater than the height of the forming sheet 30, and can accommodate the forming sheet 30 to pass through, so that the two end portions 32 of the forming sheet 30 can pass through the notch 111 along the second direction b after being stacked and connected to the winding portion 22, and the two connecting portions 33 of the forming sheet 30 are stacked and passed through the notch 111.

[0043] In some embodiments, in order to increase the rigidity of the shell 10 and prevent the shell 10 from being deformed, the notch 111 does not completely penetrate the side wall 11 in the first direction a, that is, the length of the notch 111 in the first direction a is smaller than the length of the through hole 12 along the first direction a.

[0044] In some embodiments, the notch 111 can also be completely disposed through the side wall 11 in the first direction a. This facilitates deformation of the side wall 11 through the notch 111 so as to install the rotating member 20 in the through hole 12 .

[0045] In some embodiments, see Figures 3 to 5 The rotating member 20 is arranged in the through hole 12, so that the side wall 11 is located on the peripheral side of the rotating member 20, that is, the side wall 11 is sleeved on the outer periphery of the rotating member 20, so that the two end portions 32 of the forming sheet 30 can pass through the notch 111 along the second direction b after being stacked and connected to the same position of the rotating member 20, specifically connected to the winding portion 22.

[0046] In some embodiments, the rotating member 20 includes a limiting portion 21 and a winding portion 22, the limiting portion 21 is fixedly connected to the winding portion 22, and the axis c of the winding portion 22 coincides with the axis c of the limiting portion 21, that is, the limiting portion 21 is connected to one end of the winding portion 22 along the first direction a. The limiting portion 21 is used to connect the housing 10, so that the rotating member 20 can rotate around the axis c relative to the side wall 11, and the rotating member 20 only has the degree of freedom to rotate around the axis c, and does not have the degree of freedom to move along the first direction a or the second direction b. The side wall 11 is spaced from the outer periphery of the winding portion 22, and the space is used to accommodate the forming sheet 30 wound around the outer periphery of the winding portion 22, so that when the rotating member 20 rotates around the axis c relative to the housing 10, the two connecting portions 33 of the forming sheet 30 are gradually stacked and wound around the outer periphery of the winding portion 22.

[0047] The above-mentioned annular forming sheet structure 100 is installed with the rotating member 20 through the through hole 12, so that the side wall 11 is sleeved on the outer periphery of the rotating member 20, and the rotating member 20 can rotate around the rotating axis relative to the side wall 11. By bending one end of the forming sheet 30 toward the other end of the forming sheet 30, an annular main body 31 for sleeve teeth can be formed. By stacking the two end portions 32 of the forming sheet 30 and passing through the notch 111 and then connecting to the same position of the winding part 22, and by driving the rotating member 20 to rotate, the two connecting portions 33 of the forming sheet 30 can be gradually stacked and wound around the outer periphery of the winding part 22, so that the annular main body 31 is gradually reduced; the outer periphery of the shell 10 and the winding part 22 can accommodate the forming sheet 30 wound around the outer periphery of the winding part 22. Therefore, such an annular forming sheet structure 100 can enclose an annular main body 31 for sleeve teeth, and can also adjust the size of the annular main body 31 to adapt to the user's teeth, so as to better repair the user's teeth.

[0048] In some embodiments, see Figures 2 to 4 The rotating member 20 is provided with a notch 24, which extends along the first direction a, and the notch 24 passes through the limiting portion 21 and the winding portion 22 along the first direction a. The rotating member 20 can be driven to rotate relative to the side wall 11 around the axis c, so that the opening 242 of the notch 24 is aligned with the notch 111, so that the notch 24 can communicate with the outside through the opening 242 and the notch 111 along the second direction. The notch 24 can accommodate two buckles 321 arranged at the two ends 32, and the notch 111 can accommodate two connecting portions 33 stacked and extending along the second direction b, and the opening 242 of the notch 24 can allow the two stacked connecting portions 33 to pass through.

[0049] In some embodiments, both ends 32 of the forming sheet 30 are provided with a buckle 321, and the two buckles 321 are stacked. The two stacked buckles 321 and the two stacked connecting portions 33 can move from one end of the slot 24 close to the limiting portion 21 along the first direction a toward the winding portion 22, and the buckle 321 enters the slot 24. At this time, the connecting portion 33 is penetrated in the notch 111 and can pass through the opening 242 of the slot 24, so that the buckle 321 of the end 32 is located in the slot 24.

[0050] In some embodiments, the slot 24 has a first stop surface 241, and the first stop surface 241 is arranged opposite to the buckle 321, and the first stop surface 241 is used to stop the buckle 321 from moving out of the slot 24 along the second direction b toward the opening 242 of the slot 24. When in use, the opening 242 of the slot 24 is aligned with the notch 111, and the two buckles 321 and the two connecting parts 33 are stacked and aligned with the slot 24, and the stacked buckles 321 and the connecting parts 33 are moved from one end of the slot 24 close to the limiting part 21 toward the winding part 22 along the first direction a, specifically from the bottom of the slot 24 upward to the inner top of the slot 24, and the buckle 321 completely enters the slot 24. In this way, the first stop surface 241 can stop the buckle 321 from moving toward the opening 242 of the slot 24 in the opposite direction of the second direction b to prevent the buckle 321 from detaching from the slot 24 during the rotation of the rotating member 20 around the axis c, thereby making the connection between the forming sheet 30 and the winding portion 22 more stable.

[0051] In some embodiments, the opening 242 of the notch 24 is disposed on the first stop surface 241 , and an opening 242 is formed between the two first stop surfaces 241 . The opening 242 is the opening 242 of the notch 24 , and the gap 111 and the notch 24 are connected through the opening 242 .

[0052] In some embodiments, see Figure 2-Figure 4 The buckle 321 is a hook, and the hook faces the opening 242 of the slot 24. The widest part of the hook cannot pass through the opening 242 of the slot 24, and the hook moves in the opposite direction of the second direction b and abuts against the first stop surface 241 to prevent the buckle 321 from being separated from the slot 24 during the rotation of the rotating member 20 around the axis c.

[0053] In some embodiments, see Figures 3 to 6 The limiting portion 21, the winding portion 22 and the adjusting portion 23 are all cylindrical. The limiting portion 21, the winding portion 22 and the adjusting portion 23 are all cylindrical, and the axes c of the limiting portion 21, the winding portion 22 and the adjusting portion 23 are all coincident.

[0054] In some embodiments, see Figures 3 to 6 The size of the limiting portion 21 is larger than the size of the winding portion 22. Specifically, the diameter of the limiting portion 21 is larger than the diameter of the winding portion 22. The area of ​​the side where the limiting portion 21 is connected to the winding portion 22 is larger than the area of ​​the side where the winding portion 22 is connected to the limiting portion 21. When the limiting portion 21 is connected to the winding portion 22, the portion of the limiting portion 21 other than the portion overlapping with the winding portion 22 forms a second stop surface 211.

[0055] In some embodiments, the side wall 11 has a third stop surface 112, and the third stop surface 112 is arranged on the inner periphery of the side wall 11. When the side wall 11 is arranged on the peripheral side of the rotating member 20, the second stop surface 211 is arranged opposite to the third stop surface 112, wherein the second stop surface 211 faces upward and the third stop surface 112 faces downward, and the first stop surface 241 and the second stop surface 211 abut against each other to limit the movement of the rotating member 20 relative to the side wall 11 along the first direction a. It can be understood that the first direction a refers to the direction from bottom to top.

[0056] In some embodiments, see Figures 3 to 6 The annular forming sheet structure 100 further includes an adjusting portion 23, which is fixedly connected to an end of the winding portion 22 away from the limiting portion 21, that is, the limiting portion 21, the winding portion 22 and the adjusting portion 23 are sequentially connected along the first direction a.

[0057] In some embodiments, the size of the adjusting portion 23 is larger than the size of the winding portion 22, specifically, the diameter of the adjusting portion 23 is larger than the diameter of the winding portion 22, the area of ​​the side where the adjusting portion 23 is connected to the winding portion 22 is larger than the area of ​​the side where the winding portion 22 is connected to the adjusting portion 23, and when the adjusting portion 23 is connected to the winding portion 22, the portion of the adjusting portion 23 other than the portion overlapping with the winding portion 22 forms a fourth stop surface 231.

[0058] In some embodiments, the side wall 11 further has a fifth stop surface 113, which is disposed on the inner periphery of the side wall 11. When the side wall 11 is disposed on the peripheral side of the rotating member 20, the fourth stop surface 231 is disposed opposite to the fifth stop surface 113, wherein the fourth stop surface 231 faces downward and the fifth stop surface 113 faces upward, and the fourth stop surface 231 abuts against the fifth stop surface 113 to limit the rotating member 20 from moving in the opposite direction of the first direction a relative to the side wall 11. It can be understood that the first direction a refers to the direction from top to bottom.

[0059] In this way, the second stop surface 211 , the third stop surface 112 , the fourth stop surface 231 and the fifth stop surface 113 are provided to limit the vertical movement of the rotating member 20 , so that the rotating member 20 connected to the housing 10 has only the freedom to rotate around the axis c.

[0060] In some embodiments, see Figure 1 , Figures 3 to 6 The outer circumference of the adjusting portion 23 is provided with a plurality of protrusions 232, which are arranged at intervals of equal radius with the axis c as the center of the circle, so that the outer circumference of the adjusting portion 23 can form a gear shape, and the protrusions 232 are used to contact the inner wall of the side wall 11. Compared with the adjusting portion 23 with a smooth outer circumference, the adjusting portion 23 with the protrusions 232 can more easily rotate relative to the side wall 11 around the axis c.

[0061] In some embodiments, see Figure 2 , Figures 3 to 5 The housing 10 further includes two pressing blocks 13, which are spaced apart and connected to the two ends of the side wall 11 with the notch 111, so that a gap corresponding to the notch 111 is formed between the two pressing blocks 13. The pressing blocks 13 extend in the opposite direction of the second direction b, and the spacing of the gap 131 is the same as the spacing of the notch 111, and the spacing corresponds to the notch 111, so that the notch 111 and the gap 131 can accommodate two overlapping connection parts 33. By providing two pressing blocks 13 to form the gap 131, it is beneficial to make the two connection parts 33 overlap, and it is convenient for the overlapped connection parts 33 to be wound around the winding part 22 as the rotating member 20 rotates.

[0062] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The housing 10 further includes a convex ring 14, which is connected to the outer periphery of the side wall 11 and is disposed at one end of the side wall 11 away from the limiting portion 21. The convex ring 14 is disposed around the outer periphery of the side wall 11 and is located at an end 32 of the side wall 11, specifically at the uppermost end of the side wall 11, to stop the adjustment tool 200 from moving along the first direction a, that is, to prevent the adjustment tool 200 from moving upward relative to the side wall 11.

[0063] In some embodiments, the outer periphery of the side wall 11 is provided with two oppositely disposed clamping surfaces 114, which are used to be clamped by the adjusting tool 200 to prevent the side wall 11 from rotating relative to the adjusting tool 200. The clamping surfaces 114 are provided between the convex ring 14 and the pressing block 13, and the pressing block 13 is used to stop the adjusting tool 200 from moving in the opposite direction of the first direction a, that is, to prevent the adjusting tool 200 from moving downward relative to the side wall 11.

[0064] In some embodiments, the clamping surface 114 is located directly above the two pressing blocks 13, and the center of the clamping surface 114 coincides with the center of the two pressing blocks 13. After the adjustment tool 200 is connected to the side wall 11, the annular body 31 can be driven to fit onto the user's teeth by holding the adjustment tool 200, which is convenient for medical staff to operate and use.

[0065] In this way, the convex ring 14 and the pressure block 13 can prevent the adjusting tool 200 from moving up and down relative to the side wall 11, and the two clamping surfaces 114 can prevent the adjusting tool 200 from rotating relative to the side wall 11, so that the adjusting tool 200 and the side wall 11 can be stably connected.

[0066] In some embodiments, see Figure 7The adjusting tool 200 includes a clamping member 210 , which is disposed between the convex ring 14 and the pressing block 13 , and the clamping member 210 clamps the two clamping surfaces 114 , so that the adjusting tool 200 is connected to the annular forming sheet structure 100 through the clamping member 210 and the connecting side wall 11 .

[0067] In some embodiments, a connection groove 233 is provided at one end of the adjusting portion 23 away from the winding portion 22, and the connection groove 233 is used to connect with the adjusting tool 200, so that the adjusting tool 200 can drive the adjusting portion 23 to rotate so that the rotating member 20 rotates around the axis c. The connection groove 233 is provided at the top end of the adjusting portion 23, and the adjusting tool 200 can connect to the rotating member 20 through the connection groove 233, so that the adjusting tool 200 drives the rotating member 20 to rotate around the axis c.

[0068] In some embodiments, the adjustment tool 200 further includes a cutter head 220 , the connecting groove 233 is a quadrangular groove, the cutter head 220 matches the connecting groove 233 , and the rotating member 20 can be rotated around the axis c by rotating the cutter head 220 .

[0069] In some embodiments, the adjustment tool 200 further includes a handle 230, the clamp 210 is fixedly connected to the handle 230, and the blade head 220 is rotatably connected to the handle 230. Thus, when the clamp 210 is connected to the side wall 11, the blade head 220 is connected to the connection groove 233.

[0070] When in use, align the blade head 220 with the connecting groove 233, connect the clamping member 210 to the side wall 11, and the medical staff holds the handle 230 to put the annular body 31 on the user's teeth, and drives the blade head 220 to rotate relative to the handle 230 to make the rotating member 20 rotate around the axis c. At this time, the side wall 11 is fixed by the clamping member 210, and the side wall 11 cannot rotate relative to the rotating member 20.
