Description

Technical Field

[0001] The utility model relates to the technical field of fixation training devices, and more specifically, to a fixation training card. Background Art

[0002] Fixation training is a practical behavioral training measure to improve patients' cognitive ability, enhance cooperation awareness and psychological endurance. It mainly practices the patient's eyes to fix on a certain point without moving for a certain period of time by simulating the surgical scenario. The purpose of fixation training is to improve the patient's ability to fixate during surgery or before certain ophthalmic examinations, so as to improve the patient's compliance behavior during the operation, reduce the exposure time of the ocular surface during the operation, shorten the operation time, and reduce the patient's anxiety and tension, so as to reduce the discomfort and fatigue of the eyes during the operation. During the process of fixation training, auxiliary tools are needed for training.

[0003] Usually, the patient is required to cover the non-surgical eye with one hand, keep both eyes open, and let the surgical eye fix on a point (fingertip) or an ophthalmic pupil pen, and keep the eyes still for 30 seconds. The patient can blink when tired. The recommended duration of each practice is 5 minutes, and it is recommended to perform 3 to 5 times of training before surgery to carry out the work of fixation training.

[0004] However, in the process of using the above method, the initiative of the patient is not good. The reason is that there is no physical reference, which is inconvenient for training and affects the effect of fixation training. Although the effect of fixation can be achieved, the training is not very convenient and affects the effect of fixation training. In order to further improve the effect of fixation training and facilitate the patient to carry out fixation training, a fixation training card is proposed. Summary of the Utility Model

[0005] The utility model provides a fixation training card, which solves the problem of inconvenient use in the related technology.

[0006] The technical solution of the utility model is as follows: A fixation training card includes a blue handle and a training mechanism. The training mechanism includes a rotatable shaft installed on the inner wall of the blue handle and a blue panel fixedly connected to the outer surface of the shaft. A yellow marker is fixedly connected to the outer surface of the blue panel. A limiting hole is formed on the outer surface of the blue panel. Two symmetrically arranged through holes are formed at the top of the blue handle. A limiting rod is slidably sleeved on the inner wall of each through hole. One end of each limiting rod is fixedly connected with a disc. A telescopic spring is fixedly connected to the outer surface of each disc. The other end of each telescopic spring is fixedly connected to the outer surface of the blue handle. The two telescopic springs are respectively sleeved on the outside of the two limiting rods.

[0007] Further, a dial is fixedly connected to the outer surface of each of the discs, and an anti-slip layer is coated on the outside of each of the dials. By providing the dials, the contact area of the discs can be increased, facilitating the pulling of the discs, and thus facilitating the folding and storage of the blue panel and the yellow marker.

[0008] Further, the width value of the blue handle is greater than the diameter value of the yellow marker, and the thickness values of both the blue panel and the yellow marker are less than the thickness value of the inner groove of the blue handle. By defining the dimensional relationship among the blue handle, the blue panel, and the yellow marker, when the blue panel is stored inside the blue handle, the yellow marker will not be exposed, thereby reducing the probability of damage or contamination to the surface of the blue panel and increasing the service life of the device.

[0009] Further, the diameter values of both of the through holes are the same as the diameter value of the limit hole, and the diameter value of the limit rod is the same as the diameter value of the limit hole. By defining the dimensional relationship among the limit hole, the through holes, and the limit rod, the limit rod can be inserted into the limit hole, facilitating the folding and storage of the blue panel and improving the practicality of the device.

[0010] Further, anti-slip pads are fixedly connected to both sides of the outer surface of the blue handle, and anti-slip patterns are provided on the outer surface of each of the anti-slip pads. By providing the anti-slip pads, the friction on the surface of the blue handle can be increased, facilitating the patient to hold the device more stably for fixation training.

[0011] Further, a protective shell is fixedly connected to one side surface of the blue handle, and both of the discs are located inside the protective shell. By providing the protective shell, the movement range of the discs can be limited, preventing the limit rod from falling off when being pulled.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, through the mutual cooperation between the blue handle and the training mechanism, the patient can hold the blue handle and perform fixation training by staring at the yellow marker. Compared with staring at the fingertips or finding a certain point by oneself for fixation training, the device has a higher-quality fixation training effect. At the same time, when not in use, the blue panel and the yellow marker can be folded and stored in the blue handle, and the yellow marker will not be exposed, providing protection for the surface of the yellow marker, reducing the probability of damage to the yellow marker, extending the service life of the device, and also reducing the volume occupied by the device, making it more practical.

[0021] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] As Figures 1 to 5 shown, this embodiment proposes a fixation training card, including a blue handle 1 and a training mechanism 2. The training mechanism 2 includes a rotatable rotating shaft 201 installed on the inner wall of the blue handle 1 and a blue panel 202 fixedly connected to the outer surface of the rotating shaft 201.

[0024] The blue panel 202 can rotate in the inner wall of the blue handle 1 through the provided rotating shaft 201, thus facilitating subsequent storage and folding work.

[0025] The outer surface of the blue panel 202 is fixedly connected with a yellow marker 203. When the patient conducts training through this device, they can fix their eyes on the yellow marker 203 for fixation training. Moreover, the color difference formed between the blue panel 202 and the yellow marker 203 can more conveniently enable the patient to fix their eyes on the yellow marker 203 for training, improving the intraoperative eye position coordination, shortening the operation time and at the same time shortening the eye surface exposure time, with relatively strong practicability.

[0026] The yellow marker 203 here can be a conventional round plate with a yellow marker. At the same time, a fluorescent layer can be added to its surface so that it can be used normally in a dim environment, enabling the patient to train independently before surgery. Also, for more convenient training, it can also be a yellow light source of the same volume to achieve the purpose of being closer to the intraoperative scene, thereby reducing the patient's anxiety and tension during the operation. If a yellow light source is used, a corresponding mobile or wired power supply device needs to be set up by oneself.

[0027] Limit holes 204 are provided on the outer surface of the blue panel 202, and two symmetrically arranged through holes 205 are provided at the top of the blue handle 1. A limit rod 206 is slidably sleeved on the inner wall of each through hole 205.

[0028] The diameter values of the two through holes 205 are the same as the diameter value of the limit hole 204, and the diameter value of the limit rod 206 is the same as the diameter value of the limit hole 204. By defining the dimensional relationship among the limit hole 204, the through hole 205, and the limit rod 206, the limit rod 206 can be inserted into the limit hole 204, facilitating the folding and storage of the blue panel 202 and improving the practicality of the device.

[0029] One end of each limit rod 206 is fixedly connected to a disc 207, and a telescopic spring 208 is fixedly connected to the outer surface of each disc 207. The other end of each telescopic spring 208 is fixedly connected to the outer surface of the blue handle 1. The two telescopic springs 208 are respectively sleeved outside the two limit rods 206.

[0030] When the disc 207 is pulled, the corresponding telescopic spring 208 can be stretched. When the telescopic spring 208 deforms, an elastic force can be generated, and the disc 207 can be reset by means of the generated elastic force.

[0031] A dial 209 is fixedly connected to the outer surface of each disc 207, and an anti-slip layer is coated on the outside of each dial 209. By setting the dial 209, the contact area of the disc 207 can be increased, facilitating the pulling of the disc 207, and thus facilitating the folding and storage of the blue panel 202 and the yellow marker 203.

[0032] As Figure 1 shown, this state is the use state. At this time, the top limit rod 206 is inserted into the limit hole 204 to achieve the limiting of the blue panel 202. When not in use, the top disc 207 can be pulled outwards to move the limit rod 206 out of the limit hole 204, releasing the limit on the blue panel 202.

[0033] Then the blue panel 202 can be rotated downwards by 180 degrees, and the disc 207 located below can be pulled outwards, so that the blue panel 202 can be rotated to asFigure 3 In the shown state, then release the pulled disk 207. With the elasticity of the telescopic spring 208, the limit rod 206 can be snapped into the limit hole 204, so as to realize the storage and positioning of the blue panel 202 and the yellow marker 203 as shown in Figure 3 the shown state.

[0034] Moreover, the yellow marker 203 will not leak out, which can effectively reduce the probability of damage to the yellow marker 203 and improve the service life of the device.

[0035] Embodiment 2

[0036] As shown in Figures 1 to 5 , based on the same concept as the above Embodiment 1, this embodiment also proposes that the width value of the blue handle 1 is greater than the diameter value of the yellow marker 203, and the thickness values of the blue panel 202 and the yellow marker 203 are both smaller than the thickness value of the inner groove of the blue handle 1. By defining the dimensional relationship among the blue handle 1, the blue panel 202 and the yellow marker 203, when the blue panel 202 is stored inside the blue handle 1, the yellow marker 203 will not be exposed. In this way, the probability of damage or contamination on the surface of the blue panel 202 can be reduced, and the service life of the device can be improved.

[0037] Anti-slip pads 3 are fixedly connected to both sides of the outer surface of the blue handle 1, and anti-slip patterns are provided on the outer surface of each anti-slip pad 3. By setting the anti-slip pads 3, the friction on the surface of the blue handle 1 can be increased, which is convenient for the patient to hold the device more stably for the fixation training work.

[0038] A protective shell 4 is fixedly connected to one side surface of the blue handle 1, and both disks 207 are located inside the protective shell 4. By setting the protective shell 4, the movement range of the disks 207 can be limited, and the situation that the limit rod 206 falls off when being pulled can be avoided.

[0039] Working principle: In the state shown in Figure 1 , the patient can hold the blue handle 1 with one hand, cover one eye with the other hand, keep both eyes open, and look at the yellow marker 203 in the middle of the blue panel 202. The patient needs to keep the operative eye still for 30 seconds without turning, which can improve the eye position cooperation during the operation, shorten the operation time and at the same time shorten the eye surface exposure time. When the device is used up, the top disk 207 can be pulled, and the outer surface of the disk 207 is made to contact the surface of the protective shell 4, so that the top limit rod 206 is removed from the limit hole 204. At the same time, the limiting work on the blue panel 202 is released, and then the blue panel 202 is rotated downward by 180 degrees. At the same time, the lower disk 207 is pulled outward, and the outer surface of the disk 207 is made to contact the surface of the protective shell 4. When the blue panel 202 is rotated to the state as shown in Figure 3In the shown state, when the pulled disc 207 is released, the corresponding lower limit rod 206 will reset by the elastic force of the telescopic spring 208, causing the limit rod 206 to snap into the limit hole 204, realizing the folding, storage and limiting of the blue panel 202. In this way, the yellow marker 203 can be protected when not in use, reducing the probability of damage to the yellow marker 203 when not in use, extending the service life of the device, and being more practical. When in use, according to the above steps of folding and storage, the blue panel 202 can be unfolded to the state as shown in Figure 1 for use.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
