Description

Technical Field

[0001] The invention relates to a training device, in particular to an eye fixation training device. Background Art

[0002] Laser surgery for myopia is a laser surgery for correcting myopia. It includes six development stages: laser optical keratectomy (PhotoRefractive Keratectomy, referred to as PRK), excimer laser in situ keratomileusis (Lasik, referred to as IK), excimer laser subepithelial keratomileusis (LASEK, referred to as EK), wavefront aberration-guided excimer laser surgery (TorsionLasik, referred to as TK), femtosecond, and all-femtosecond laser.

[0003] During laser surgery for myopia, keeping the eyeballs fixed is related to the success or failure of the entire surgery, that is, if the patient's eyeballs move too frequently during the operation, the operation will be interrupted or terminated directly. Therefore, before laser surgery for myopia, eyeball fixation training will be performed. The existing method is: the patient lies on his back on the bed, and then a fixed object is fixed directly above the eyes. Then, the upper and lower eyelids of one eye of the patient are opened, and the patient is asked to look directly at the fixed object for 1 minute. Then, the other eye is trained in turn, and the training is performed alternately for 20 minutes every day until the patient's eyes can cooperate with the surgery and remain motionless. Although this method is simple, it has the following disadvantages: during the training process, since the eyelids need to be opened by hand, and the training time is long, it will increase the difficulty of operation for patients and their families; in addition, during the training process, due to the long training time, the head is easily offset, which will affect the training effect.

DETAILED DESCRIPTION

[0041] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0042] See also Figures 1 to 11 The present invention provides an eye fixation training device, comprising a head pad 100, a top plate 200, an eyelid opening mechanism 300 and an eye positioning mechanism 400, for eye fixation training.

[0043] The head pad 100 is used to support the patient's head and other parts. A positioning groove 110 is provided on the head pad 100 for placing and fixing the head. When in use, the patient is allowed to lie on his back and place his head in the positioning groove 110 to prevent the head from moving around. In the specific implementation process, an auxiliary fixing device such as a fixing belt can be provided on the head pad 100 to fix the head, which can further improve the fixing effect and further improve the fixation effect.

[0044] The top plate 200 is arranged above the headrest 100 through two oppositely arranged brackets 210. There are two eyelid opening mechanisms 300, which are respectively arranged on the brackets 210 and can open the left eyelid or the right eyelid of the patient respectively.

[0045] When in use, the two eyelid opening mechanisms 300 can be used to open the two eyes in turn, so that the two eyes can be trained to fixate in turn, or the two eyelid opening mechanisms 300 can be used to open the two eyes at the same time, so that the two eyes can be trained to fixate at the same time. The eyeball positioning mechanism 400 is arranged on the top plate, and is used to attract and fix the eyeball.

[0046] When in use, the patient lies in a supine position with the head placed in the positioning groove 110. Then, the upper and lower eyelids of one eye are opened with the eyelid opening mechanism 300, and the patient is asked to stare at the eye positioning mechanism 400 for one minute. Then, the eyelid of the other eye is opened in turn, and the patient is asked to stare at the eye positioning mechanism 400 for one minute. In this way, the two eyes can be trained alternately for at least 20 minutes a day.

[0047] See also Figure 1 to Figure 2 In the present embodiment, the eyelid opening mechanism 300 comprises a mounting frame 310, a support plate 320, a guide rod 330 and an adjusting rod 340. The eyelid opening mechanism 300 is in a mouth shape and is arranged on the bracket 210. The guide rod 330 is arranged in the mounting frame 310. There are two support plates 320. The two support plates 320 are located in the mounting frame 310 and are slidably connected with the guide rod 330. The adjusting rod 340 is a double-threaded rod. After the adjusting rod 340 is inserted into the mounting frame 310, it is threadedly connected with the two support plates 320. Rotating the double-threaded rod can drive the two support plates 320 to move relative to or away from each other.

[0048] When it is necessary to open the eyes, close the eyes and slide the entire eyelid opening mechanism 300 until the bottoms of the two support plates 320 respectively contact the upper and lower eyelids, and then rotate the adjustment rod 340 to drive the two support plates 320 to move away from each other, so that the upper and lower eyelids can be opened.

[0049] As a preferred embodiment, a guide groove 220 is opened on the inner wall of the bracket 210 along its height direction, and a clamping block is provided on the side wall of the mounting frame 310, which can be slidably clamped in the guide groove 220, and a locking assembly 350 is provided on the clamping block, which can be locked on the bracket 210.

[0050] The locking assembly 350 is used to fix the position of the entire eyelid opening mechanism 300 during the eyelid opening process, thereby preventing the eyelid opening mechanism 300 from sliding up and down and affecting the opening effect.

[0051] Specifically, the locking assembly 350 includes a tongue 351 and an elastic member. A limiting hole is provided on the end of the bracket 210 near the eye, and a mounting hole is provided on the side wall of the clamping block. The tongue 351 can be slidably inserted into the mounting hole through the elastic member, and when the mounting hole is aligned with the limiting hole, the tongue 351 can be inserted into the limiting hole, and when the tongue 351 is pressed again, the tongue 351 can be retracted into the mounting hole. The locking assembly 350 is locked to prevent the eyelid opening mechanism 300 from moving up and down.

[0052] See also Figures 2 to 3 As a more preferred embodiment, the eyelid opening mechanism 300 further includes an unlocking block 360, which includes an elastic sheet 361 and a pressing block 362. The elastic sheet 361 is disposed on the bracket 210, and the pressing block 362 is disposed at the end of the elastic sheet 361 and aligned with the limiting hole. When the pressing block 362 is pressed, the pressing block 362 can press the inserting tongue 351 inserted in the limiting hole back into the mounting hole.

[0053] When the fixation training is completed, the pressing block 362 is pressed first. After the pressing block 362 presses the tongue 351 back into the mounting hole, the entire eyelid opening mechanism 300 can be moved in the direction of the top plate 200, so that the head can be easily removed from the head pad 100.

[0054] See also Figure 1 , Figure 2 and Figure 4 In this embodiment, the eyeball positioning mechanism 400 includes a mounting plate 410 and a light source 420. The mounting plate 410 is arranged on the top plate 200, and the light source 420 is arranged on the mounting plate 410 and is located close to the eye. The light source 420 can emit light. When in use, the patient can stare at the light source 420 to achieve the effect of attracting and fixing the eyeball. In specific implementation, the light source 420 can be a fixed light source or a photoelectric light source that flashes quickly and slightly. However, it should be noted that the light emitted by the light source 420 cannot cause damage to vision.

[0055] See also Figures 4 to 11 As a preferred embodiment, the eye fixation training device further includes a light source adjustment component 500. The light source adjustment component 500 is arranged on the mounting plate 410 and is located on the side close to the eye. A light leakage hole 510 is provided in the middle of the adjustment mechanism of the light source adjustment component 500, and the light leakage hole 510 is coaxially arranged with the light source 420, and the size of the light leakage hole 510 is adjustable.

[0056] Since the size of the light leakage hole 510 is adjustable, the effect of the light source 420 observed by the patient can be changed, thereby attracting the patient's attention and further preventing the eyeball from moving, thereby improving the training effect.

[0057] At the same time, since the size of the light leakage hole 510 is adjustable, this effect is similar to the process of all-femtosecond surgery on the eye, so that patients can become familiar with the surgical process in advance, reduce their fear during the operation, and further improve the training effect.

[0058] Specifically, the light source adjustment assembly 500 includes a bottom plate 520, a light shielding sheet 530, a rotating disk 540 and a driver 550. The bottom plate 520 is arranged on the mounting plate 410 through a connecting frame, a through hole 521 is provided at the center of the bottom plate 520, a plurality of jacks 522 are provided at even intervals in the circumferential direction on the bottom plate 520, a plurality of first slide grooves 523 are provided at even intervals in the circumferential direction on the edge of the bottom plate 520, and the first slide grooves 523 are perpendicular to the radius of the bottom plate 520.

[0059] The light blocking sheet 530 is a quadrilateral and is located between the base plate 520 and the mounting plate 410. There are multiple light blocking sheets 530, and the multiple light blocking sheets 530 are circumferentially arranged and connected to form a sheet-shaped light blocking film, and the edges of two adjacent light blocking sheets 530 are slidably connected, and the head end of each light blocking sheet 530 extends toward the center of the base plate 520, and the head ends of all the light blocking sheets 530 form a light leakage hole 510, and each light blocking sheet 530 is provided with a second slide groove 531 that is staggered with the center of the base plate 520, and a second latch 532 is provided at the tail end of the light blocking sheet 530, and the second latch 532 can be slidably inserted in the corresponding first slide groove 523.

[0060] The rotating disk 540 is located between the light-blocking film and the mounting plate 410. The edge of the rotating disk 540 is rotatably connected to the connecting frame. A plurality of first latches 541 are arranged on the rotating disk 540 at circumferential intervals, and the first latches 541 slide through the corresponding second slide grooves 531 and then are inserted into the corresponding sockets 522. The driver 550 is arranged on the base plate 520 and can drive the rotating disk 540 to rotate clockwise or counterclockwise.

[0061] See also Figure 6 In the initial state, the front end of the light shielding sheet 530 points to the center of the bottom plate 520. At this time, the light leakage holes 510 formed at the front ends of all the light shielding sheets 530 are in a closed state. When the driving assembly drives the rotating disk 540 to rotate clockwise, through the interaction between the second slide groove 531, the second latch 532, the first slide groove 523, and the first latch 541, all the light shielding sheets 530 can be offset in the direction away from the center of the bottom plate 520, so that the light leakage holes 510 can be gradually enlarged, and the light source observed by the patient becomes larger and larger (please refer to Figure 7On the contrary, when the driving assembly drives the rotating disk 540 to rotate counterclockwise, through the interaction between the second slide groove 531, the second latch 532, the first slide groove 523, and the first latch 541, all the light shielding sheets 530 can be offset toward the center of the bottom plate 520, so that the light leakage hole 510 can be gradually reduced, and the light source observed by the patient becomes smaller and smaller until the light leakage hole 510 is completely closed (see Figure 6 ).

[0062] As a preferred embodiment, a slot is provided on the side wall of the light shielding sheet 530, and a slider is provided on the side wall of the light shielding sheet 530 connected thereto, and the slider can be slidably locked in the slot. Through the cooperation of the slot and the slider, the coordination between the light shielding sheets 530 can be better, and the light shielding sheets 530 can be prevented from interfering with each other during the sliding process.

[0063] In this embodiment, the driver 550 includes a bidirectional rotation power source 551 and a driving gear 552. The bidirectional rotation power source 551 is arranged on the top plate 200, the driving gear 552 is arranged on the power output shaft of the power of the bidirectional rotation power source 551, and the side wall of the rotating disk 540 is provided with teeth, and the driving gear 552 is meshed with the teeth.

[0064] The driving gear 552 is driven to rotate by the bidirectional rotating power source 551, and the rotating disk 540 is driven to rotate by the driving gear 552. Then, the light blocking plate 530 can be driven to shift to the left or right through the interaction among the second slide groove 531, the second latch 532, the first slide groove 523, and the first latch member 541.

[0065] The use of the above eye fixation training device:

[0066] When in use, the patient adopts a supine position and supports the head in the positioning groove 110 of the head pad 100;

[0067] Then, close both eyes and slide the entire eyelid opening mechanism 300 until the inserting tongue 351 is inserted into the limiting hole. At this time, the bottoms of the two support plates 320 are respectively against the upper and lower eyelids. Then, rotate one of the adjustment rods 340 to drive the two support plates 320 to move in opposite directions, so that the upper and lower eyelids of the corresponding eyes can be opened.

[0068] Next, start the rotating power source and the light source 420, then ask the patient to stare at the position of the light source 420 and keep it there for one minute. Then, within another minute, the diameter of the light leakage hole 510 changes continuously. Then, open the other eye in turn for fixation training. In this way, the two eyes can be trained alternately for at least 20 minutes a day.

[0069] With this device, there is no need to manually open the eyelids during the entire training process, which greatly reduces the workload of patients and guardians. In addition, the light source and head position are fixed throughout the entire smooth process, thereby improving the training effect.

[0070] In addition, since the size of the light leakage hole 510 is adjustable, the effect of the light source 420 observed by the patient can be changed to attract the patient's attention, further prevent the eyeball from rotating, and achieve the purpose of improving the training effect. At the same time, since the size of the light leakage hole 510 is adjustable, this effect is similar to the full femtosecond process of the eye, so that the patient can be familiar with the surgical process in advance, reduce the fear during the operation, and further improve the training effect.
