Detailed implementation manners

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] As Figures 1 to 3 shown, an eye surgery simulation trainer is disclosed in this embodiment, including a base 1. A pedestal 2 is arranged on the top surface of the base 1. Two sets of human eye components are arranged on the top surface of the pedestal 2. A facial model cover 3 is arranged above the base 1. Eye holes 301 are arranged at positions corresponding to the two sets of human eye components on the facial model cover 3. The eye holes 301 just expose the human eye components located below the facial model cover 3 to the outside.

[0038] Among them, the human eye component mainly includes an eyelid simulator 4 and a human eye simulator 5; the eyelid simulator 4 simulates the closing or opening of the eyelids, and the human eye simulator 5 simulates the eyeball. It is arranged below the eyelid simulator 4. When the eyelid simulator 4 closes, it blocks the human eye simulator 5.

[0039] As Figure 4 shown, the eyelid simulator 4 includes two relatively arranged arc-shaped eyelid rods 401 that can be elastically closed. Rod shafts 402 are arranged at both ends of the arc-shaped eyelid rods 401. The rod shafts 402 are rotatably connected to the rod seats 403. Arc-shaped baffles 404 are arranged on the sides of the two arc-shaped eyelid rods 401 facing away from each other.

[0040] A torsion spring 405 is sleeved on the rod shaft 402. One end of the torsion spring 405 is connected to the arc-shaped eyelid rod 401, and the other end is connected to the rod seat 403. The two arc-shaped eyelid rods 401 approach each other under the action of the torsion spring 405, thereby driving the two arc-shaped baffles 404 to close, for simulating the closing of the eyes.

[0041] As Figure 5and 6 As shown in 6 , the human eye simulator 5 includes a sphere 501 disposed in a sphere holder 502. The sphere 501 has a cavity structure, and a balloon 503 simulating vitreous humor is disposed in the sphere 501. At the center of the top end of the upper half of the sphere 501, there is a hole 504. Outside the hole 504, there is a flexible transparent cover 509 simulating the cornea. The flexible transparent cover 509 is made of a colloidal material and can be easily cut by a scalpel. The edge of the flexible transparent cover 509 is connected to the inner wall of the hole 504. Inside the hole 504, there is a flexible partition 505 simulating the iris. The flexible partition 505 adheres to the balloon 503. An opening 506 simulating the pupil is provided on the flexible partition 505. Inside the opening 506, there is a thin-walled sac 507, and a number of microspheres 508 are filled in the thin-walled sac 507.

[0042] The balloon 503 can be filled with water. The balloon 503 and the sphere 501 cooperate to clamp and fix the flexible partition 505. The edge of the flexible transparent cover 509 is provided with an adhesive that can be repeatedly torn and adhered. The flexible transparent cover 509 is adhered to the inner wall of the hole 504 through the adhesive and can be replaced and updated at any time. The thin-walled sac 507 is used to simulate the capsule outside the lens, and a number of microspheres 508 filled in the thin-walled sac 507 are used to simulate the diseased lens.

[0043] When performing a simulated operation, first make an incision on the flexible transparent cover 509. Through the incision, insert a surgical instrument into the opening 506 to perform a circumferential tear on the front part of the thin-walled sac 507. Then, use a negative pressure instrument to suck out all the microspheres 508 in the thin-walled sac 507, and then implant a new intraocular lens through the incision on the flexible transparent cover 509.

[0044] In the simulated operation, the thin-walled sac 507 and the flexible transparent cover 509 are disposable consumables. The flexible transparent cover 509 can be directly replaced from the outside of the sphere 501. In order to facilitate the replacement of the thin-walled sac 507 inside the sphere 501, in this embodiment, as Figure 7 shown, the sphere 501 includes an upper spherical shell 501-1 and a lower spherical shell 501-2. The upper spherical shell 501-1 and the lower spherical shell 501-2 are assembled and cooperate. The upper spherical shell 501-1 and the lower spherical shell 501-2 can specifically be connected together by a threaded structure. Among them, the hole 504 is provided at the center of the top end of the upper spherical shell 501-1.

[0045] At the center of the bottom end of the lower spherical shell 501-2, an elastic support member 501-3 is fixed. The elastic support member 501-3 is inserted into the sphere holder 502.

[0046] As Figure 8 and 9As shown, the sphere retainer 502 includes a receiving body 502-1. A ball receiving cavity 502-2 for holding the sphere 501 is provided on the receiving body 502-1. An upwardly convex inserting platform 502-3 is provided at the bottom of the ball receiving cavity 502-2. A jack 502-4 is provided at the top of the inserting platform 502-3. The jack 502-4 is in plug-in fit with the elastic support member 501-3.

[0047] During the simulated surgical process, medicated liquid is flushed into the eyeball. This part of the medicated liquid will drip along the sphere 501 to the bottom of the ball receiving cavity 502-2. Therefore, the ball receiving cavity 502-2 also serves to hold the flushing medicated liquid. The upwardly convex inserting platform 502-3 at the bottom of the ball receiving cavity 502-2 can prevent the medicated liquid from flowing into the jack 502-4. At the same time, further, an annular shielding cap 501-4 is provided on the elastic support member 501-3. The annular shielding cap 501-4 covers the inserting platform 502-3. The annular shielding cap 501-4 also has the function of guiding the flow, preventing the medicated liquid from entering the jack 502-4.

[0048] In this embodiment, the jack 502-4 is a through hole penetrating the bottom end of the receiving body 502-1. By pushing upward from the lower end of the jack 502-4 with a push rod, the entire sphere 501 can be pushed out of the sphere retainer 502.

[0049] The human eyeball is pulled by the muscles around the eyeball. The elastic support member 501-3 provides elastic support for the entire sphere 501. When performing surgery on the sphere 501, being restricted and pulled by the elastic support member 501-3, it can rotate and return to its position like a real eye, effectively simulating the condition of a real eye and making the training and practical operation conditions closer. The elastic support member 501-3 is a columnar body made of rubber.

[0050] As Figure 9 and 10 shown, an inserting plate 502-5 is provided on the outer wall of the bottom end of the receiving body 502-1. A guiding sliding slot 201 that is in plug-in fit with the inserting plate 502-5 is provided on the base 2; through the above-designed plugging structure, the human eye simulator 5 can be quickly installed below the eyelid simulator 4, or quickly withdrawn from below the eyelid simulator 4.

[0051] An identifier 502-6 for indicating the insertion direction is further provided on the inserting plate 502-5, which is convenient for the operator to operate.

[0052] As Figure 10 and 11As shown, a conduit 502-7 is provided on the outer wall of the receiving body 502-1, and the conduit 502-7 communicates with the ball receiving cavity 502-2. A drawer slot 101 is provided on one side wall of the base 1, a drawer box 102 is provided in the drawer slot 101, a conduit hole 103 is provided at the top of the base 2, and the conduit 502-7 extends into the drawer box 102 through the conduit hole 103. The liquid medicine in the ball receiving cavity 502-2 is exported through the conduit 502-7 and placed in the drawer box 102.

[0053] In this embodiment, a plurality of vertically arranged connecting pins 104 are provided on the base 1, magnets are provided at the upper ends of the connecting pins 104, and the magnets are in adsorption cooperation with the metal inserted in the facial model cover 3. The facial model cover 3 can be quickly installed on or removed from the base 1 through the magnetic attraction structure.

[0054] A top cover 105 is provided on the base 1. After the simulated surgical operation is completed, the top cover 105 can be covered on the entire base 1 to protect the facial model cover 3, the human eye simulator 5, and the eyelid simulator 4.

[0055] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
