[0002] Myopia causes axial lengthening and retinal pathological changes, which seriously affect the visual health of patients and has become a major public health issue for adolescent eye health. Some myopic patients develop high myopia (over 600 degrees), which leads to axial lengthening, retinal disease and optic nerve atrophy, and even blindness, causing huge economic burdens on families, society and the country.

[0003] Posterior scleral reinforcement is a surgical method that uses allogeneic or heterogeneous materials to reinforce the thinned posterior sclera of the eyeball. It aims to control and reduce the progression of myopia, stabilize myopia, and prevent the occurrence and progression of macular and posterior retinal degeneration, thereby saving the visual function of some patients with rapidly progressive high myopia. It is an effective surgical method to prevent further progression of myopia.

[0004] During the development of posterior scleral reinforcement surgery, posterior scleral reinforcements have emerged. The posterior scleral reinforcement includes a support pad and a support belt connected to the support pad. The support pad is placed on the outer side of the posterior sclera of the eyeball, and the pressure side of the support pad is in contact with the outer side of the posterior sclera; the support belt is then fixed to the scleral wall, and the support pad is fixed by the support belt; the pressure side of the support pad can be in close contact with the outer side of the posterior sclera, which is used to shorten the axial length of the macular area, reduce the refractive power, and play a role in adjusting the axial length of the eyeball.

[0040] See also Figures 1 to 7 , Figure 1 Shows Figure 1 Schematic diagram of the structure of a molding die for a posterior sclera reinforcement 30 according to an embodiment of the present invention; Figure 2 Shows Figure 1 The schematic diagram of the decomposition structure shown; Figure 3 Shows Figure 2 A schematic diagram of the enlarged structure at A; Figure 4 Shows Figure 1 A structural diagram of a second mold 20 from one viewing angle; Figure 5 Shows Figure 4 A schematic diagram of the enlarged structure at B; Figure 6 A schematic structural diagram of a posterior sclera reinforcement 30 according to an embodiment of the present invention from one viewing angle is shown; Figure 7Another perspective structural schematic diagram of a posterior sclera reinforcement 30 according to an embodiment of the present invention is shown. An embodiment of the present invention provides a molding die for a posterior sclera reinforcement 30, and the molding die for the posterior sclera reinforcement 30 includes a first mold 10 and a second mold 20. The first mold 10 is provided with a first surface 11. The first surface 11 is provided with a first molding cavity 111 adapted to one side surface of the posterior sclera reinforcement 30. The second mold 20 is provided with a second surface 21. The second surface 21 is provided with a second molding cavity 211 adapted to the other side surface of the posterior sclera reinforcement 30. When the first mold 10 and the second mold 20 are aligned and combined together, the first molding cavity 111 and the second molding cavity 211 are combined to form a chamber adapted to the posterior sclera reinforcement 30. When the size parameters of the chamber are adjusted by controlling, the size parameters of the posterior sclera reinforcement 30 can be adjusted accordingly.

[0041] In the process of producing and processing the posterior sclera reinforcement member 30, the molding die of the posterior sclera reinforcement member 30 is used to inject the material to be molded (e.g., silicone liquid) into the first molding cavity 111, the support body (not shown in the figure, such as a metal titanium sheet, wrapped inside the silicone to play a supporting role) is placed in the first molding cavity 111, and the material to be molded is injected into the second molding cavity 211, and then the first mold 10 and the second mold 20 are aligned and combined together, and then the molding die is heated to a preset temperature, and the molding die is kept at a preset pressure and preset temperature for a preset time, and then the mold is opened to obtain the posterior sclera reinforcement member 30. In the obtained posterior sclera reinforcement member 30, the periphery of the support body is wrapped with colloid, which meets the product quality requirements of the posterior sclera reinforcement member. In this way, the posterior sclera reinforcement member 30 can be produced efficiently and with high quality by using the molding die of the posterior sclera reinforcement member 30.

[0042] In one embodiment, the first molding cavity 111 includes a first groove 1111, a second groove 1112 and two third grooves 1113 respectively connected to the first groove 1111. The second molding cavity 211 includes a fourth groove 2111, a fifth groove 2112 and two sixth grooves 2113 respectively connected to the fourth groove 2111. The fourth groove 2111 is arranged corresponding to the first groove 1111, the fifth groove 2112 is arranged corresponding to the second groove 1112, and the sixth groove 2113 is arranged corresponding to the third groove 1113. The space area enclosed by the first groove 1111 and the fourth groove 2111 is adapted to the adjustment cavity 31 of the posterior scleral reinforcement 30, the space area enclosed by the second groove 1112 and the fifth groove 2112 is adapted to the first support band 32 of the posterior scleral reinforcement 30, and the space area enclosed by the third groove 1113 and the sixth groove 2113 is adapted to the second support band 33 of the posterior scleral reinforcement 30. In this way, the posterior sclera reinforcement 30 produced by the molding mold includes an adjustment cavity 31 and a first support band 32 and two second support bands 33 connected to the adjustment cavity 31.

[0043] In one embodiment, the two third grooves 1113 are arranged at an angle, and the angle between the two third grooves 1113 is a, and a is 145° to 175°, for example 168° to 172°, and more specifically, a is 170°. In this way, the angle between the two second support belts 33 obtained by molding is correspondingly a. According to the analysis of the structure of the human eyeball and the results of the previous animal test, the posterior scleral reinforcement 30 has a better treatment effect when it is arranged in this range.

[0044] In addition, the second groove 1112 is respectively arranged at an angle with the two third grooves 1113, and the angle between the second groove 1112 and any one of the third grooves 1113 is b, and b is 94° to 96°. Specifically, b is 95°. Accordingly, the angle between the first support belt 32 formed and any one of the second support belts 33 is b. Since the fifth groove 2112 is arranged correspondingly to the second groove 1112, and the sixth groove 2113 is arranged correspondingly to the third groove 1113, that is, the relationship between the fifth groove 2112 and the sixth groove 2113 is similar to the relationship between the second groove 1112 and the third groove 1113, which will not be repeated here.

[0045] In addition, the first groove 1111 and the fourth groove 2111 are both, for example, grooves with a circular cross section perpendicular to the groove depth direction, and the adjustment cavity 31 of the posterior scleral reinforcement 30 formed in this way is, for example, disc-shaped. Of course, the first groove 1111 and the fourth groove 2111 can also be other shapes, and the obtained adjustment cavity 31 is correspondingly other shapes, which are not limited here.

[0046] As an optional solution, the angle a may also be in other ranges, such as 60° to 140°. Correspondingly, the angle b may also be in other ranges, such as 110° to 150°.

[0047] See also Figure 3 , Figure 5 and Figure 6 In one embodiment, at least one first positioning post 112 is disposed on the bottom wall of the first molding cavity 111. At least one second positioning post 212 is disposed on the bottom wall of the second molding cavity 211 corresponding to the first positioning post 112. The first positioning post 112 and the second positioning post 212 can be inserted into the blood vessel passage hole 311 of the posterior sclera reinforcement 30. In this way, during the manufacturing process of the posterior sclera reinforcement 30, the first positioning post 112 and the second positioning post 212 are both penetrated into the through hole of the support body, and the posterior sclera reinforcement 30 finally formed is formed with the blood vessel passage hole 311.

[0048] Specifically, the first positioning column 112 is disposed on the bottom wall of the first groove 1111, and the second positioning column 212 is disposed on the bottom wall of the fourth groove 2111. In addition, the first positioning column 112 and the second positioning column 212 both include a thick column disposed in the middle of the first groove 1111 or the fourth groove 2111 and a plurality of thin columns disposed at intervals around the periphery of the thick column. The posterior scleral reinforcement 30 formed in this way has a plurality of blood vessel passage holes 311, including a large hole disposed in the middle of the adjustment cavity 31, and a plurality of small holes disposed at intervals around the periphery of the large hole.

[0049] It should be noted that the specific number of the first positioning column 112 and the second positioning column 212 is not limited here, and can be set accordingly according to the blood vessel passage hole 311 of the support body. In addition, the material of the first positioning column 112 and the second positioning column 212 can be the same as the material of the first mold 10 and the second mold 20, and can be obtained by integrated molding; of course, they can also be different from the material of the first mold 10 and the second mold 20, and can be respectively set on the first mold 10 and the second mold 20 by, for example, welding, clamping, threaded connection, etc.

[0050] It should be noted that the "first positioning column 112" can be "a part of the first mold 10", that is, the "first positioning column 112" is integrally formed with the "other parts of the first mold 10"; it can also be an independent component that can be separated from the "other parts of the first mold 10", that is, the "first positioning column 112" can be independently manufactured and then combined with the "other parts of the first mold 10" into a whole. As shown in Figure 3, in one embodiment, the "first positioning column 112" is a part of the "first mold 10" that is integrally formed.

[0051] See also Figure 3 , Figures 5 to 7 In one embodiment, the bottom wall of the first molding cavity 111 is provided with an arcuate convex surface adapted to one side surface of the adjustment cavity 31 of the posterior sclera reinforcement 30. Specifically, the bottom wall of the first groove 1111 is provided with an arcuate convex surface, so that an inner concave surface is formed on one side surface of the adjustment cavity 31, and the inner concave surface contacts the outer side of the posterior sclera to firmly fix the posterior sclera.

[0052] In addition, the bottom wall of the second molding cavity 211 is provided with an arcuate concave surface adapted to the other side of the adjusting cavity 31. Thus, the bottom wall of the fourth groove 2111 is provided with an arcuate concave surface, so that an outer convex surface is formed on the other side of the adjusting cavity 31.

[0053] See also Figures 5 to 7In one embodiment, the bottom wall of the first molding cavity 111 or the second molding cavity 211 is provided with anti-skid patterns 40. Specifically, the bottom wall of the third groove 1113 or the bottom wall of the sixth groove 2113 is provided with anti-skid patterns 40, so that the side of the second support belt 33 is provided with anti-skid patterns 40, so that the second support belt 33 can be fixed on the scleral wall more stably.

[0054] See also Figure 3 , Figures 5 to 7 In one embodiment, the first surface 11 is provided with a first glue overflow groove (not shown in the figure) located at the periphery of the first molding cavity 111, and the first glue overflow groove extends to the periphery of the first surface 11 and communicates with the external environment. And / or, the second surface 21 is provided with a second glue overflow groove 213 located at the periphery of the second molding cavity 211, and the second glue overflow groove 213 extends to the periphery of the second surface 21 and communicates with the external environment. In this way, during the production and processing of the posterior sclera reinforcement 30, on the one hand, during the processing of the material to be molded in the chamber, the material to be molded overflowing from the chamber can enter the first glue overflow groove or the second glue overflow groove 213, and be discharged to the external environment through the first glue overflow groove or the second glue overflow groove 213; on the other hand, the first glue overflow groove and the second glue overflow groove 213 are connected to the external environment, which can avoid the vacuum state of the combination part between the first mold 10 and the second mold 20 after the posterior sclera reinforcement 30 is processed and molded, resulting in the inability to separate the first mold 10 and the second mold 20 to take out the posterior sclera reinforcement 30.

[0055] See also Figure 2 In one embodiment, at least one first jack 12 is provided on the first mold 10 and / or the second mold 20, and the first jack 12 is used to install an electric heating rod (not shown in the figure). A second jack 13 is provided on the first mold 10 and / or the second mold 20, and the second jack 13 is used to set a temperature sensing probe (not shown in the figure). In this way, the first mold 10 and the second mold 20 are heated to a preset temperature by inserting the electric heating rod into the first jack 12, and the temperature of the first mold 10 and the second mold 20 is sensed by the temperature sensing probe, and the heating power and heating time of the electric heating rod are controlled accordingly. In addition, as an optional solution, the electric heating rod can also be omitted. In the process of producing and processing the posterior scleral reinforcement 30, the first mold 10 and the second mold 20 are molded together and placed in a temperature box, and the first mold 10 and the second mold 20 are heated to a preset temperature and a preset time by the temperature box, or the heat is transferred to the first mold 10 or the second mold 20 by the heating plate contacting the outer wall of the first mold 10 and the second mold 20.

[0056] See also Figure 1 and Figure 2In one embodiment, the first mold 10 and the second mold 20 are both made of stainless steel; the hardness of the stainless steel is 48° to 52°. In this way, the stability of the forming mold during the processing can be guaranteed, and the mirror surface processing process of the stainless steel can be successfully completed, and the production efficiency of the forming mold can be greatly improved, thereby reducing the maintenance frequency of the forming mold.

[0057] See also Figure 1 and Figure 2 In one embodiment, at least one first positioning portion 113 is provided on the first surface 11, and at least one second positioning portion 214 corresponding to the first positioning portion 113 is provided on the second surface 21, and the first positioning portion 113 is positioned and matched with the second positioning portion 214. In this way, when the first mold 10 and the second mold 20 are molded together, the first positioning portion 113 and the second positioning portion 214 are positioned and matched, so that the first mold 10 and the second mold 20 can be accurately aligned and molded together, and the molding quality of the posterior sclera reinforcement 30 can be guaranteed.

[0058] See also Figure 1 and Figure 2 In one embodiment, the first positioning portion 113 is a convex portion, and the second positioning portion 214 is a concave portion corresponding to the first positioning portion 113; there are four first positioning portions 113, and the four first positioning portions 113 are arranged one-to-one at the four corners of the first surface 11; there are four second positioning portions 214, and the four second positioning portions 214 are arranged one-to-one at the four corners of the second surface 21.

[0059] It is understandable that, as an example, the first positioning portion 113 may also be a concave portion, and the second positioning portion 214 may be a convex portion corresponding to the first positioning portion 113. As an example, the first positioning portion 113 and the second positioning portion 214 may also be other numbers, which are not limited here, as long as the first mold 10 and the second mold 20 can be accurately positioned and combined together when the first mold 10 and the second mold 20 are closed.

[0060] It should be noted that the "convex part" can be "a part of the first mold 10", that is, the "convex part" is integrally formed with the "other parts of the first mold 10"; it can also be an independent component that can be separated from the "other parts of the first mold 10", that is, the "convex part" can be manufactured independently and then combined with the "other parts of the first mold 10" into a whole. Figure 1 As shown, in one embodiment, the "convex portion" is a part of the "first mold 10" that is integrally formed.
