Description

Technical Field

[0001] The invention belongs to the technical field of eyelid expansion, and in particular relates to an adjustable eyelid expansion device. Background Art

[0002] In eye surgery, in order to prevent the patient from having the urge to blink, most methods use an eyelid dilator to separate the patient's upper and lower eyelids to ensure that the eyes are in an open state, thereby ensuring the smooth progress of the operation.

[0003] Although some reusable eyelid speculums drive the eyelids to expand evenly to both sides via a rotating shaft, some people may have slight asymmetry in the upper and lower eyelid muscles due to factors such as lifestyle habits, and the eyelid speculum is clamped and fixed on the eye by two eyelid muscles. This results in a certain deviation between the center point of the eyelid speculum and the center point of the eye when using the eyelid speculum, which may easily lead to one side being wider and the other side being narrower, and is not convenient for doctors to operate. At the same time, since children's eyelids and eye tissues are relatively soft and sensitive, using the dilator for too long may cause additional pressure on the eye tissues, causing discomfort or even damage. Therefore, the doctor may remove the dilator intermittently according to the progress of the operation to reduce the pressure on the eyelids and prevent long-term application of force from causing discomfort or damage to the eyes. However, existing eyelid speculums can only perform a single expansion function, cannot provide reminders, and are not convenient to use. Summary of the invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6As shown, the present invention provides the following technical solutions: an adjustable eyelid expansion device includes a fixed main board 6, the fixed main board 6 is a U-shaped plate, and the end surfaces of both sides of the fixed main board 6 are provided with adjustment grooves 27, an adjustment plate 10 is rotatably arranged inside one of the adjustment grooves 27, a V-shaped rotation groove 16 is provided inside the adjustment plate 10, an expansion strip 14 is fixedly arranged inside the rotation groove 16, and the end of the expansion strip 14 extends to the outside of the adjustment plate 10 through the rotation groove 16, a first rubber layer 21 is fixedly installed at the bottom of the inner wall of the fixed main board 6, and the lower part of the side of the adjustment plate 10 close to the first rubber layer 21 is fixedly installed There is an index plate 20, the center line of the index plate 20 coincides with the center line of the expansion strip 14, the inner wall of one of the adjustment grooves 27 is symmetrically installed with a rotating shaft 9, the outer wall of the rotating shaft 9 is evenly fixedly installed with a protrusion 24, the lower part of both sides of the adjustment plate 10 is symmetrically provided with a rotating hole 23, the inner wall of the rotating hole 23 is symmetrically provided with a fixed groove 25, the protrusion 24 is embedded in the inside of the fixed groove 25, the side walls of the fixed main board 6 are symmetrically provided with grooves 5, the inner wall of the groove 5 is fitted with a cushion layer 7, the groove 5 is embedded and connected with the ear, and the cushion layer 7 is used to fill the gap between the inner wall of the groove 5 and the ear.

[0025] Through the above technical solution, when in use, the patient's head is slightly lifted, and the fixed main board 6 is placed under the patient's head. At this time, the index plate 20 points to the patient's eyes. The position of the fixed main board 6 is adjusted by the index plate 20 so that the center line of the index plate 20 is aligned with the center of the patient's eye. Then the patient's head is put down, and the downward pressure of the patient's head is used to make it rest on the fixed main board 6, and then the adjustment plate 10 and the expansion bar 14 are fixed to one side of the patient's eye. Then, the adjustment plate 10 is turned to make it rotate with the rotating axis 9 as the center, driving the expansion bar 14 to rotate, forcing the expansion bar 14 to contact the patient's eyelid. Since the expansion bar 14 is fixed to the side of the patient's eye by the fixed main board 6, the eyelid muscles cannot push the expansion bar 14 to move, thereby ensuring that the center point of the eyelid opener overlaps with the center point of the eye, thereby eliminating the problem of the eyelid opener being wide on one side and narrow on the other side when in use.

[0026] When wearing the fixed main board 6, the patient's ears are embedded in the groove 5. The embedded connection is used to further increase the fixed connection between the fixed main board 6 and the patient's head, preventing the fixed main board 6 from being displaced during surgery. The first rubber layer 21 installed on the bottom of the inner wall of the fixed main board 6 is used to increase the comfort of the patient and reduce the discomfort caused by the fixed main board 6 during the patient's surgery.

[0027] When the adjustment plate 10 is rotated, the protrusion 24 is disengaged from the current fixing groove 25 under the pressure of the inner wall of the fixing groove 25, and is embedded into the corresponding fixing groove 25 after rotation. The interlocking connection between the protrusion 24 and the fixing groove 25 ensures that the adjustment plate 10 will not be displaced during the operation.

[0028] Furthermore, a through hole 15 is provided on the side wall of the adjustment plate 10 , and a lower pressing plate 3 is embedded inside the through hole 15 . The lower pressing plate 3 is triangular, and auxiliary grooves 22 are evenly spaced on the inclined surface of the lower pressing plate 3 . The auxiliary grooves 22 are embedded and connected with the expansion strip 14 .

[0029] Please refer to Figures 1-3 and Figure 5 When the expansion strip 14 contacts the patient's eyelid, by pressing the lower pressure plate 3, the inner wall of the auxiliary groove 22 is used to squeeze the two ends of the expansion strip 14 and force it to expand gradually. Since the expansion strip 14 is evenly expanded to both sides due to the lower pressure plate 3, the eyelid is prevented from becoming wider on one side and narrower on the other side due to its own elasticity. In conjunction with the fixed main board 6, it is further ensured that the upper and lower eyelids expand evenly to both sides.

[0030] When retracting the expansion strip 14, it is only necessary to manually release the contact between the expansion strip 14 and the eyelid, and push the lower pressure plate 3 from the bottom to the top, forcing the expansion strip 14 to be separated from the inside of the auxiliary groove 22. The expansion strip 14 can be immediately reset under the action of its own elastic force, which is convenient for use.

[0031] Furthermore, a limiting groove 11 is provided in the middle of one end of the lower pressure plate 3 away from the first rubber layer 21, and a dispensing tube 12 is fixedly installed on the surface of the side of the adjustment plate 10 away from the first rubber layer 21. The dispensing tube 12 is a T-shaped structure, and the dispensing tube 12 is embedded in the limiting groove 11. A clamping ring 2 is evenly installed on the part of the expansion strip 14 extending to the outside of the adjustment plate 10. The clamping ring 2 is away from the first rubber layer 21, and a hose 13 is passed through the inside of the clamping ring 2. One end of the hose 13 is connected to the dispensing tube 12, and a plurality of water outlet holes 1 are evenly spaced on the side of the hose 13 away from the dispensing tube 12. A clamping groove 4 is fixedly installed on the surface of the side of the adjustment plate 10 away from the first rubber layer 21. The clamping groove 4 is located below the dispensing tube 12, and a second rubber layer 26 is fitted on the inner wall of the clamping groove 4. A sponge layer 17 is passed through the inside of the dispensing tube 12 and the hose 13.

[0032] Please refer to Figures 1-5Before the operation, the lubricating eye drops bottle can be embedded in the inside of the card slot 4, and the static friction on the surface of the second rubber layer 26 ensures that the lubricating eye drops bottle will not be detached during the operation. Then, the port of the lubricating eye drops bottle is brought into contact with the dispensing tube 12, and the lubricating eye drops bottle is pressed several times to inject the liquid inside into the dispensing tube 12 and the sponge layer 17 inside the hose 13, and the sponge layer 17 is completely wetted. Due to the porous structure of the sponge layer 17, after being completely wetted, it gradually passes through the water outlet 1 on the hose 13 under the influence of gravity and drips into the patient's eyes, completing automatic wetting. The installed clamp ring 2 ensures that the hose 13 will not be detached from the top of the expansion strip 14 during the operation. The doctor does not need to moisten it manually, which reduces the doctor's workload. The doctor only needs to press the lubricating eye drops bottle when intermittently removing the dilator for convenient use.

[0033] Furthermore, a transparent tube 8 is fixedly installed on the side of the fixed main board 6 facing away from the first rubber layer 21, the transparent tube 8 is close to the adjustment plate 10, and the transparent tube 8 is located between the adjustment plate 10 and the groove 5, a light reminder 18 is fixedly installed inside the transparent tube 8, a button 19 is fixedly installed on the side of the adjustment plate 10 close to the first rubber layer 21, the button 19 is close to the adjustment plate 10, and the button 19 is located between the adjustment plate 10 and the groove 5, the button 19 is located directly below the index plate 20, and the distance between the button 19 and the adjustment groove 27 is less than the length of the index plate 20.

[0034] Please refer to Figures 1-2 and Figure 5 When the adjustment plate 10 is turned to rotate around the rotation axis 9, the guide plate 20 that originally played a guiding role also moves synchronously and finally hits the button 19, and then the light reminder 18 is activated by the button 19 to start timing. During the operation, when the preset time is reached, the light reminder 18 immediately starts to flash and reminds the doctor by changing the light to prevent the sound alarm from suddenly reminding the doctor when the doctor is highly focused, thereby stimulating the doctor's problem. When the doctor adjusts and removes the expansion strip 14 and rotates the adjustment plate 10 to reset, the guide plate 20 immediately breaks away from the contact with the button 19, and the light reminder 18 immediately stops working and stops flashing.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
