Description

Technical Field

[0001] This utility model relates to the field of corneal refractive surgery technology, and in particular to a portable fixation trainer that simulates different surgical fixation light sources. Background Technology

[0002] A fixation trainer is a medical assistive device designed specifically for pre-operative ophthalmic surgery. By simulating surgical scenarios (such as a closed, dark environment) and dynamic light sources (such as a green LED flashing mode), combined with an adjustable-height modular structure, a magnetic protective frame, and a timing function, it helps patients, especially elderly cataract patients and those undergoing laser eye surgery, to train their eye stability. This enables them to maintain focus on a target for more than 30 seconds during surgery, thereby improving cooperation, shortening surgical time, and reducing operational risks caused by eye movement.

[0003] The current traditional fixation training method involves placing a finger about 30cm away from the chest, opening both eyes simultaneously, covering one eye, and staring at the fingertip with the other eye for more than 20 seconds to complete the preoperative fixation training. However, since the surgical environment is quite different from the training environment, some patients are still prone to blinking or eye movement during the operation due to nervousness, which may lead to certain risks. Therefore, there is an urgent need for a fixation trainer that can simulate the ophthalmic surgical scenario to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of traditional fixation training methods in the aforementioned technologies, which cannot simulate the intraoperative scenario and thus fail to achieve optimal fixation training results for patients, this invention provides a portable fixation trainer that simulates different surgical fixation light sources.

[0012] As an improvement of this utility model, the clamping assembly includes an adjusting base and an adjusting clamping plate. The adjusting base is provided with a hollow threaded post, and the adjusting clamping plate is fitted with an adjusting locking post. The hollow threaded post passes through the adjusting clamping plate and is threadedly connected to the adjusting locking post.

It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0023] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0024] Please see Figure 1This utility model discloses a portable fixation training device that simulates different surgical gaze light sources. It includes a fixation device 1 and a clamping assembly 4. The fixation device 1 includes a working surface and a mounting surface. The working surface is equipped with training light sources 3 of different colors, and the mounting surface is equipped with an adjustment assembly 2. A main control board is located inside the fixation device 1. The clamping assembly 4 is fixedly connected to the fixation device 1 via the adjustment assembly 2. The fixation device 1 is clamped and fixed by the clamping assembly 4, and the placement angle and position of the fixation device 1 are adjusted by the adjustment assembly 2. Through the clamping assembly 4, the fixation device 1 can be arbitrarily clamped in a suitable area, such as the head or foot of a hospital bed. The use of the fixation device 1 can be adjusted by adjusting the component 2 on the protective board, tabletop, and other items that provide clamping conditions, so as to ensure that the patient can achieve the best use effect at the optimal distance. The training light source 3 mainly includes green light source and warm light source. Green light source can reduce eye energy consumption, relax extraocular muscles and ciliary muscles, and indirectly relieve eye fatigue. Warm light source is usually red. Warm light source is softer and more comfortable for human eyes and is also conducive to eye muscle relaxation. The combination of green and red light source can improve the training quality and training effect of the patient.

[0025] In this embodiment, the working surface of the fixation device 1 is provided with a refractive light source 31 and an auxiliary light source 32. At least one auxiliary light source 32 is arranged circumferentially on one side of the refractive light source 31. The refractive light source 31 mainly emits green light, and the auxiliary light source 32 mainly emits warm-colored light. When the fixation device 1 is working, the patient focuses on the refractive light source 31 with both eyes. The green light emitted from the center of the refractive light source 31 will gradually become blurred and the brightness will gradually weaken. The patient needs to keep looking at the refractive light source 31 for more than 20 seconds to simulate the scene and process in ophthalmic surgery. The auxiliary light source 32 can help the patient adapt to the light better, and the warm-colored light source is also more beneficial for the patient to stare at the light source for a long time.

[0026] In this embodiment, the back of the fixation device 1 is provided with a gear adjustment switch 8 and a power switch 7. The gear adjustment switch 8 is used to control the switching between the diopter lamp source 31 and the auxiliary lamp source 32, and the power switch 7 is used to control the start or stop of the fixation device 1.

[0027] In this embodiment, the adjustment assembly 2 includes a universal connecting rod, a universal ball joint 23, and a locking member 22 for locking the universal ball joint 23. One end of the universal adjusting rod 21 is fixedly connected to the universal ball joint 23, and the other end of the universal adjusting rod 21 is fixedly connected to the clamping assembly 4. The universal adjusting rod 21 can be bent and shaped at will, which allows the fixation device 1 to be adjusted in position on the XYZ three axes. With the universal ball joint 23, the fixation device 1 can be adjusted to multiple different angles. After being adjusted to a suitable position, the locking member 22 locks the universal ball joint 23 to fix the current angle of the fixation device 1 and keep it stationary.

[0028] In this embodiment, the clamping assembly 4 includes an adjusting base 41 and an adjusting clamping plate 42. The adjusting base 41 is provided with a hollow threaded post 44, and the adjusting clamping plate 42 is fitted with an adjusting locking post 43. The hollow threaded post 44 passes through the adjusting clamping plate 42 and is threadedly connected to the adjusting locking post 43. The universal adjusting rod 21 passes through the adjusting locking post, the adjusting clamping plate 42 and the threaded hollow post in sequence and is fixedly connected to the adjusting base 41. Rotating the adjusting locking post 43 causes the adjusting clamping plate 42 to move toward the adjusting base 41, so that the adjusting base 41 and the adjusting clamping plate 42 retract and clamp, clamping in any position such as a table or bed board, which improves practicality and portability.

[0029] In this embodiment, the clamping surfaces of the adjusting base 41 and the adjusting clamp 42 are both provided with anti-slip silicone pads 5. The anti-slip silicone pads 5 can effectively increase the friction between the adjusting base 41 and the adjusting clamp 42 and the clamped surface, maintain the stability of the clamping, and prevent the fixation device 1 from sliding and other problems caused by the adjusting base 41 and the adjusting clamp 42 not being clamped tightly during training.

[0030] In this embodiment, the fixation device 1 is also equipped with a battery, and the mounting surface is also equipped with a charging interface 6. The battery and the charging interface 6 are electrically connected to the main control board. The fixation device 1 can be carried around without having to be plugged in all the time to turn it on, which improves the overall portability of the product. When the battery is depleted, it can be charged through the charging interface 6, and it can be turned on and used while charging. Compared with surgical training devices that need to be plugged in all the time, this product is more convenient.

[0031] The working principle of this utility model is as follows:

[0032] In use, first, use the clamping component 4 to install and fix the fixation device 1 on the bed board or table, etc., and use the adjustment component 2 to adjust the angle and position of the fixation device 1 to ensure that the angle is most suitable for the patient during training, so as to ensure the training effect and quality. Then, press the power switch 7 on the mounting surface of the fixation device 1 to turn on the fixation device 1. Use the gear adjustment switch 8 on the mounting surface to adjust the training light source 3, which can be adjusted to the refractive light source 31 or the auxiliary light source 32. The refractive light source 31 is green light, and the auxiliary light source 32 is warm light. The two can be flexibly switched according to the patient's needs.

[0033] The advantages of this utility model are:

[0034] This invention, by installing a clamping component and an adjustment component on the fixation device, allows the fixation device to be freely clamped and installed on items such as bed boards and tables. The training light source can simulate the color of the light emitted during eye surgery, providing patients with a more realistic and accurate fixation training scenario that simulates eye surgery, thereby achieving better fixation training results.

[0035] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
