[0043] As shown in the figure, an eyeball model for simulating glaucoma surgery provided by an embodiment of the present invention includes an eye model base body 1 and a plurality of detachable modules 2. The eye model base body 1 and one or more detachable modules 2 are assembled to form a complete eyeball model.

[0044] The eyeball model includes a cornea 3, a sclera 4, an iris 5, and a ciliary body 6. The cornea 3 and the sclera 4 are located on the outer layer, and the iris 5 and the ciliary body 6 are located on the inner layer.

[0045] The outer wall of the detachable module 2 is located at the junction of the sclera 4 and the cornea 3 and extends into the eyeball model.

[0046] The detachable module 2 also has a trabecular meshwork 7 at the junction of the sclera 4 and the cornea 3. The state of the trabecular meshwork 7 is any one of open angle, closed angle, incision, resection, implantation of a glaucoma drainage device, and implantation of a drainage tube, and the states of the trabecular meshwork 7 in different detachable modules 2 are different.

[0047] In view of the problems existing in the prior art, this application provides an eyeball model for simulating glaucoma surgery, including an eye model base body 1 and a plurality of detachable modules 2. The eye model base body 1 and one or more detachable modules 2 are assembled to form a complete eyeball model. The eyeball model includes a cornea 3, a sclera 4, an iris 5, and a ciliary body 6. The cornea 3 and the sclera 4 are located on the outer layer, and the iris 5 and the ciliary body 6 are located on the inner layer. The outer wall of the detachable module 2 is located at the junction of the sclera 4 and the cornea 3 and extends into the eyeball model. The detachable module 2 also has a trabecular meshwork 7 at the junction of the sclera 4 and the cornea 3. The state of the trabecular meshwork 7 is any one of open angle, closed angle, incision, resection, implantation of a glaucoma drainage device, and implantation of a drainage tube, and the states of the trabecular meshwork 7 in different detachable modules 2 are different. The eyeball model for simulating glaucoma surgery provided by this application intuitively demonstrates the principle and process of glaucoma surgery, has specialty characteristics, is intuitive and targeted, helps patients and their families better understand the surgical method and principle, and thus better cooperate with the treatment.

[0048] Specifically, for the eyeball model simulating glaucoma surgery provided by the present application, the eye model matrix 1 shows the main structure of the eyeball, which can play a role in educating and explaining to patients and their families at various knowledge levels; and the set detachable module 2 can show different states of the trabecular meshwork 7, helping patients understand the different states of the trabecular meshwork 7 in a normal eyeball or in glaucoma, and can also show the treatments and effects brought by different glaucoma surgeries on the trabecular meshwork 7, helping patients and their families better understand the surgery, achieving good and sufficient doctor-patient communication, and laying a foundation for perioperative treatment.

[0049] In the present application, the state of the trabecular meshwork 7 being any one of open angle, closed angle, incision, resection, implantation of a glaucoma drainage device, and implantation of a drainage tube is a state well-known in the ophthalmic field. Specifically, when the trabecular meshwork 7 is in an open angle state, it means that the angle is open, aqueous humor flows back normally, and the human eye is in a normal working state. When the trabecular meshwork 7 is in a closed angle state, it is a state where the trabecular meshwork is blocked by iris tissue, aqueous humor cannot flow back and accumulates, resulting in increased intraocular pressure. The incision of the trabecular meshwork 7 is an internal drainage surgery, which means cutting a part of the trabecular meshwork along the direction of the junction line of the cornea 3 and the iris 5, and its function is to establish a direct aqueous humor drainage channel. The resection of the trabecular meshwork 7 means cutting a part of the trabecular meshwork and the corresponding corneal and scleral lamella along the vertical direction of the junction line of the cornea 3 and the iris 5. At the same time, when performing trabeculectomy, partial resection of the iris root at the corresponding part is required, which is called peripheral iridectomy, and its function is also to establish a direct aqueous humor drainage channel. The implantation of a glaucoma drainage device into the trabecular meshwork 7 is also an internal drainage surgery, which is to implant a micro-component glaucoma drainage device with a drainage function into the trabecular meshwork 7, and its function is also to establish an aqueous humor drainage channel and reduce intraocular pressure. The implantation of a drainage tube into the trabecular meshwork 7 is to insert the drainage tube into the anterior chamber through the sclera, the cornea and the scleral junction, and its function is to drain aqueous humor into the subconjunctival space, thereby reducing intraocular pressure.

[0050] In the present application, the number of the detachable modules 2 is the same as the number of different states of the trabecular meshwork 7, which is convenient for selecting the corresponding detachable module 2 when the corresponding state needs to be shown; and the number of detachable modules 2 that can be embedded in the eye model matrix 1 can be one or more (i.e., two or more). When the number that can be embedded in the eye model matrix 1 is less than the requirement for explaining a certain surgical plan, the explanation is achieved by replacing the inserted or removed detachable module 2 at one position; when the number that can be embedded in the eye model matrix 1 is equal to or greater than the explanation requirement, the required detachable module 2 can be selected and removed for explanation.

[0051] For the convenience of operation, different detachable modules 2 can be numbered or marked.

[0052] Preferably, the eyeball model includes an outer layer, a middle layer, and an inner layer;

[0053] The outer layer includes a cornea 3 and a sclera 4. The sclera 4 is spherical and has an opening 401. The cornea 3 is covered in the opening 401.

[0054] The middle layer includes an iris 5 and a ciliary body 6. The iris 5 is annular, and its outer edge is connected to the edge of the opening 401. The ciliary body 6 is connected to the outer edge of the iris 5 and is located inside the sclera 4.

[0055] The inner layer includes the retina and retinal blood vessels;

[0056] The detachable module 2 includes a portion of the cornea 3 , a portion of the sclera 4 , a portion of the iris 5 and a portion of the ciliary body 6 , and also has a Schlemm tube 8 on the cut surface of the sclera 4 .

[0057] Specifically, the eyeball model includes an outer layer, a middle layer and an inner layer according to the physiological anatomy of the eyeball. The cornea 3, the sclera 4, the iris 5 and the ciliary body 6 are respectively located at positions corresponding to the physiological structures. The retina and retinal blood vessels in the inner layer are not very relevant to the explanation of glaucoma, so the display can be simplified by just painting or other methods.

[0058] The detachable module 2 is a block-shaped structure extending from the junction of the sclera 4 and the iris 5 into the eyeball model, and thus includes part of the cornea 3, part of the sclera 4, part of the iris 5 and part of the ciliary body 6, and the incision of the Schlemm canal 8 can also be displayed on the cut surface of the sclera 4. When the detachable module 2 is embedded in the eye model base 1, the structure of the part of the cornea 3, sclera 4, etc. contained therein is spliced ​​with the cornea 3, sclera 4, etc. of the eye model base 1 to form a complete structure. When the detachable module 2 is removed, the patient and his family can directly see the connection between the sclera 4 and the cornea 3, as well as the angle between the cornea 3 and the iris 5, and can observe the trabecular meshwork 7 located at the junction of the cornea 3 and the iris 5 (that is, the well-known angle structure in the field of ophthalmology can be seen).

[0059] The anterior chamber angle, also known as the chamber angle or the anterior chamber angle gap, is an important structure in the eye, located at the angle between the cornea and the iris, and is also a well-known structure in the art. This structure is mainly composed of the front wall, the back wall, and the recess between the two walls. The front end of the front wall is the anterior limiting ring, and behind the anterior limiting ring is the trabecular meshwork, which is the main passage for the discharge of aqueous humor. The end point of the anterior wall is the scleral process, which is a white structure. The back wall is the root of the iris. The recess is the front end of the ciliary body, which is gray-black and is also called the ciliary band. The anterior chamber angle is the main passage for aqueous humor to flow out of the eyeball. Aqueous humor is a transparent liquid produced by the ciliary body. It fills the front part of the eyeball, provides nutrition to the cornea and lens, and helps maintain normal pressure in the eyeball. When aqueous humor is produced too much or its discharge is blocked, the pressure in the eye will increase, which may lead to the occurrence of eye diseases such as glaucoma.

[0060] For the eyeball model simulating glaucoma surgery in this application, the vitreous body inside the inner layer has little relation with glaucoma surgery and can be set or not. When set, the detachable module 2 can include part of the vitreous body or not. Similarly, the structure of the lens has little relation with glaucoma and can be set or not. When set, the detachable module 2 can include it or not.

[0061] Preferably, the number of detachable modules 2 that can be embedded in the eye model matrix 1 is the same as the number of states of the trabecular meshwork 7, and each detachable module 2 demonstrates one state of the trabecular meshwork 7.

[0062] More preferably, the number of detachable modules 2 that can be embedded in the eye model matrix 1 is the same as the number of states of the trabecular meshwork 7. Then each detachable module 2 is embedded in the eye model matrix 1, and each detachable module 2 demonstrates one state of the trabecular meshwork 7, and can be taken out or inserted for demonstration as needed.

[0063] Preferably, when the state of the trabecular meshwork 7 is that a glaucoma drainage device is implanted, the glaucoma drainage device is detachably connected to the trabecular meshwork; when the state of the trabecular meshwork 7 is that a drainage tube is implanted, the drainage tube is detachably connected to the trabecular meshwork;

[0064] It also includes a matching surgical instrument model.

[0065] Preferably, when the state of the trabecular meshwork 7 is that a glaucoma drainage device is implanted, the glaucoma drainage device is detachably connected to the trabecular meshwork; when the state of the trabecular meshwork 7 is that a drainage tube is implanted, the drainage tube is detachably connected to the trabecular meshwork; it also includes a matching surgical instrument model. Then during the explanation process, a surgical instrument model (such as models of scissors, blades, forceps) can be used to simulate surgical operations, demonstrate the implantation of the drainage tube and glaucoma drainage device into the corresponding part channels, and demonstrate the surgical and drainage processes, which is more intuitive. Moreover, using a surgical instrument model can also avoid the situation of real instruments hurting people, with higher safety.

[0066] Preferably, the eye model matrix 1 is formed by assembling multiple detachable parts.

[0067] Preferably, if the eye model matrix 1 is formed by assembling multiple detachable parts, the space occupied for storage after disassembling is smaller.

[0069] It is also preferably to arrange a light strip 13 in the detachable module 2. The laying position of the light strip 13 simulates the path of aqueous humor flow, that is, starting from the ciliary body 6, bypassing the iris 5 and then penetrating into the trabecular meshwork 7 to end; when the detachable module 2 also shows the Schlemm's canal 8, the light strip 13 extends from the trabecular meshwork 7 to penetrate into the Schlemm's canal 8 to end. Moreover, the light strip includes at least three sections of split light strips 131. The split light strips 131 can be lit or extinguished independently. Then, by controlling the sequential lighting or extinguishing of the split light strips 131 at different positions, the sequential order of aqueous humor production, flow and drainage can be simulated, which is more convenient for understanding in combination with degradation.

[0070] In this application, the power supply of the light strip 13 can be built into the detachable module 2, and the power can be supplemented by charging or replacing the battery. At this time, the switch of the light strip 13 can be arranged on the detachable module 2. Alternatively, the light strip is electrically connected to the wire located in the eyeball model through contacts, and the power supply is arranged in the eye model base 1. The eyeball model can be powered by an external power supply, replacing the battery or an internal rechargeable battery; at this time, the switch of the light strip 13 can be arranged on the detachable module 2 or on the eye model base 1.

[0071] In this application, the number of detachable modules 13 provided with the light strip 13 can be one or more.

[0074] The split light strip 131 emitting white light can be a complete section or can include several sections in the middle. When including several sections, the lights can be lit sequentially, but the color of the lights is white; the same applies to the light strips 13 emitting green light and yellow light.

[0075] Preferably, the cornea 3 is transparent and the sclera 4 is white; the retinal blood vessels include red arteries and blue veins.

[0076] According to the physiological structure of the eyeball, the cornea 3 is set to be transparent, the sclera 4 is set to be white, and the retinal blood vessels include red arteries and blue veins, which is more realistic and convenient for patients and their families to understand and observe.

It can be assembled for use when needed and disassembled for storage when not needed, occupying a small space.

[0081] The base 11 can be a cuboid, and the stability of the eyeball model is ensured without tipping over by choosing the material or adding counterweights; the bracket 10 can be a support rod or other structures convenient for disassembly, installation and support.

[0082] Preferably, it further includes a storage box 12, and the storage box 12 has partition grids 121 for storing the eye model base 1, detachable modules 2, the bracket 10 and the base 11.

[0083] The eyeball model for simulating glaucoma surgery provided by this application may further include a storage box 12.
