[0023] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connection", "provided with" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the present application is understood according to the specific circumstances. Embodiment 1

[0024] The utility model discloses a ophthalmic multi-position skill training simulation teaching aid including support, person head model 1, neck model 2, replaceable eyeball model 3 and fixed eyeball model 4.

[0025] The support comprises a base 5, a height adjusting rod 6, a connecting block 7 and a human head model clamping assembly. The neck model 2 is arranged below the human head model 1, and threaded holes A are formed in the two sides of the neck model 2, which are used to be connected with the human head model clamping assembly. The height adjusting rod 6 is connected between the base 5 and the connecting block 7, and the human head model clamping assembly is connected with the connecting block 7. The height of the human head model clamping assembly connected with the connecting block 7 is adjusted through the height adjusting rod 6, so as to adjust the height of the human head model 1 and the neck model 2. During use, the height of the human head model 1 and the neck model 2 can be adjusted according to the use requirement.

[0026] The height adjusting rod 6 is any vertical rod structure capable of adjusting the height, for example, a telescopic sleeve rod provided with a locking piece 15. The total length of the height adjusting rod 6 is adjusted by locking and loosening the locking piece 15. Since the structure is a conventional structure and is not the innovative structure of the present application, the specific adjusting structure is not described herein. The base 5 is any structure capable of preventing the present application from falling during use, for example, a triangular support structure. The stability of the support structure is maintained by arranging the base 5, which is a conventional structure and is not the innovative structure of the present application, and thus the specific structure is not described herein.

[0027] The human head model clamping assembly of the present embodiment comprises two clamping plates 8 and two screw rods 9. The two clamping plates 8 are L-shaped structures formed by vertically connecting a horizontal rod (or a horizontal plate, which is uniformly referred to as a horizontal rod throughout the text) and a vertical rod (or a vertical plate, which is uniformly referred to as a vertical rod throughout the text). The vertical rod of the clamping plate 8 faces upward, and the horizontal rod is fixedly connected with the connecting block 7. The two screw rods 9 are oppositely arranged and are respectively threadedly connected with the vertical rods of the two clamping plates 8. The two screw rods 9 are connected with the threaded holes A formed on the neck model 2 through the vertical rods. Through the connection, the human head model 1 and the neck model 2 are fixed. The present application can realize the angle adjustment of the head model 1 through the bolt connection of the clamping plate 8 with the neck model 2. The specific adjustment method is as follows: loosen the screw rod 9, adjust the angle of the human head model 1, tighten the screw rod 9 after the adjustment is completed, and lock the human head model 1. The connection mode is more convenient for eye training operation, and is consistent with the actual situation that the head of a person can be raised during actual treatment.

[0028] The human head model 1 has two simulated eye sockets, one of which is a silicone eye socket 10. Utilizing the elasticity of silicone, the replaceable eyeball model 3 can be removed from and installed within the silicone eye socket 10. Through detachable connections, eyeball models with different conditions can be replaced, such as eyeballs with normal fundus examinations containing 3mm pupils, and eyeballs with 7-8mm pupils (normal fundus, fundus examination for rhegmatogenous retinal detachment, and high myopia), to simulate slit-lamp examinations (including anterior segment examinations, and fundus examinations with dilated and small pupils in multiple states using anterior speculum), indirect ophthalmoscopy, and intraocular drug injection training. Simulated lacrimal puncta and lacrimal ducts can also be placed on the upper and lower eyelids of the replaceable eyeball model 3 to simulate lacrimal duct irrigation training. The location and size of the lacrimal troughs and puncta are based on real-life models and are not shown in the attached diagram. Another eye model is a bony orbit 11. A fixed eye model 4 is placed inside the bony orbit 11. Removable silicone is filled between the fixed eye model 4 and the bony orbit 11. The bony orbit 11 also has simulated eyelids and periorbital skin made of silicone. Simulation of periorbital injection, retrobulbar anesthesia, and disinfection and draping training are conducted.

[0029] This embodiment is suitable for operation in a seated position and can perform the following eye training: slit-lamp examination (including anterior segment examination, and multi-state anterior-lens fundus examination with dilated and constricted pupils), lacrimal duct irrigation, etc. Example 2

[0030] The main difference between this embodiment and embodiment 1 is that a new design element has been added to the structure of the head model fastening component. Except for the head model fastening component and the connection method between the head model fastening component and the connecting block 7, the rest of the structure is the same as that in embodiment 1. This embodiment mainly describes the head model fastening component.

[0031] The head model securing assembly of this embodiment includes two securing plates 8, two screws 9, an outer frame 12, and a connecting rod 13. The outer frame 12 is a square frame, set on the same horizontal plane as the horizontal plate of the securing plate 8. The two securing plates 8 are each connected to the outer frame 12 by a connecting rod 13. The connecting block 7 has slots on both sides, and the horizontal plate of the securing plate 8 is detachably connected to the connecting block 7 through the slots.

[0032] The head model locking assembly of this embodiment can simulate not only seated eye operation training, but also supine eye operation training. When simulating a seated position, the locking plate 8 is locked with the connecting block 7; when simulating a supine position, the locking plate 8 is removed from the connecting block 7, and the head model locking assembly, head model 1 and neck model 2 are placed together on the operating table. The head model 1 is rotated so that its face is facing upwards (the rotation method is described in Embodiment 1 for adjusting the angle of the head model 1).

[0033] It needs to be explained that the original design of the utility model is to separately design an independent lying position operation structure including an outer frame, but storage and preservation are inconvenient, and based on this reason, the structure of the embodiment is designed (installed on the connecting block 7 to perform a sitting position operation, and after being disassembled, the lying position operation can be performed).

[0034] In the embodiment, the connecting rod 13 is used to connect the clamping plate 8 and the outer frame 12, and the connecting relationship design (the connecting relationship is shown in the attached drawings) of the connecting rod 13 and the outer frame 12 and the clamping plate 8 is adopted. Figure 3 When the clamping plate 8 is disassembled from the connecting block 7, the two clamping plates 8 can be moved outward, and then the clamping plate 8 is disassembled. In addition, when the clamping plate 8 is disassembled from the connecting block 7, the two clamping plates 8 can be pushed to the same side, so that the two clamping plates 8 are simultaneously drawn out from the clamping groove of the connecting block 7, but this mode needs to ensure that the gap between the clamping plate 8 and the outer frame 12 is greater than the connecting block 7, but if the size of the outer frame 12 is too large, the operation of the sitting position simulation will be affected, so this mode is not recommended.

[0035] The connecting rod 13 can be made of a slightly elastic material, such as a plastic rod, or an activity joint is arranged in the middle of the connecting rod, so as to increase the operable spacing of the two clamping plates 8 and facilitate the clamping or disassembly of the clamping plate 8 and the connecting block 7. When the sitting position is simulated, the head model 1 is mainly supported by the clamping plate 8, and the clamping plate 8 is clamped with the connecting block 7, and the force point is mainly in the connecting block 7, so even if the hardness of the connecting rod 13 is not enough, the stability of the head model 1 will not be affected. When the lying position is simulated, the clamping plate 8 and the outer frame 12 are placed on the training table as a whole, and the connecting rod 13 does not need to provide force, the structure of the clamping plate 8 and the outer frame 12 is stable, and the head model 1 can be supported by the outer frame 12 and the operation table, so the stability of the head model 1 can still be ensured.

[0036] In order to ensure that the head model 1 is supported by the outer frame 12 while ensuring the fixation of the head model 1 when the lying position is simulated, threaded holes B14 of different heights are arranged on the vertical plate of the clamping plate 8, the screw rod 9 is connected with the threaded hole B14 of the lower position when the lying position is simulated, the height of the head model 1 is lowered, and the head model 1 can be in contact with and supported by the outer frame 12 when the lying position is simulated; the screw rod 9 is connected with the threaded hole B14 of the higher position when the sitting position is simulated, so as to ensure that the gap between the neck model 2 and the connecting block 7 is reserved, so that the angle adjustment of the head model 1 can be performed.

[0037] In the structure of the embodiment, the rear part (the occipital position) of the head model 1 is designed as a plane, which can prevent the head model 1 from rotating and affecting the training operation when the lying position is simulated.

[0038] The embodiment can also perform training in the lying position state, for example, indirect fundus examination, peribulbar injection, retrobulbar anesthesia, intraocular injection, disinfection and linen laying, etc.

[0039] The utility model discloses a simple structure can adapt to the eye training operation of different body position, and the operation training of different eye science and technology is realized with simple structure, which reduces the cost of eye training model, saves the land area of equipment, and improves the convenience of eye training.

[0040] Finally, it is to be explained that the above preferred embodiments are only used for illustrating the technical scheme of the utility model and not for limiting, and although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details without departing from the range defined by the utility model claims.
