Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to an adjustable eyelid expander for clinical ophthalmology. Background Technology

[0002] The eyelid, also known as the eyelid, is located in front of the eyeball and forms a protective barrier. It is the eyelid that controls closing, opening, and moving the eyes. There are upper and lower eyelids, or upper and lower eyelids. The function of the eyelid is obvious: it protects the eyeball from external obstruction. The eyelid can open and close. When open, the normal position is that the upper eyelid covers about 1-2 mm above the cornea (the area above the iris), which is generally considered a normal position, ensuring unobstructed vision. The eyelid includes the eyelid skin and eyelashes. Its function is crucial, protecting the eyeball and moisturizing it.

[0003] During eye surgery, the body's natural tendency to close the eyes necessitates the use of a speculum to open the eyelids and expose the surgical area. Commonly used eyelid speculum devices typically consist of eyelid supports and elastic wires. In use, the two eyelid supports are attached to the upper and lower eyelids respectively, and the elastic wires open the eyelids to expose the surgical area. However, existing eyelid speculum devices cannot adjust the degree of opening; they can only open the upper and lower eyelids to their maximum extent using the elastic wires. This can lead to excessive expansion of the upper and lower eyelids, potentially damaging the surgical area and the junction of the upper and lower eyelids. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0021] Example

[0022] This embodiment describes an adjustable eyelid expander for clinical ophthalmology, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes a connecting rod 7, which is mainly used to connect the positioning clamp 2 and the positioning support block 5. In this embodiment, the connecting rod 7 has a "door" shaped structure. The door-shaped structure of the connecting rod 7 can better expose the field of vision of the surgical area and avoid obstructing the patient's eye surgery area. Of course, the connecting rod 7 can also adopt a U-shaped structure.

[0023] A positioning clamp 2 with an inverted "U" shape is fixed to one end of the connecting rod 7. The positioning clamp 2 is mainly used to lock onto the patient's nose bridge, thereby effectively positioning the entire device and preventing it from moving. A protective pad is fixed to the side of the positioning clamp 2 facing the patient. The protective pad is made of materials such as latex, foam, and silicone. These materials are relatively soft and can provide effective protection, making it more comfortable for the patient to wear.

[0024] The positioning clamp 2 has several ventilation holes, such as Figure 3 and Figure 4 As shown, the ventilation holes are evenly distributed along the circumference of the positioning hoop 2. Through the ventilation holes, the positioning hoop 2 can be ventilated inside and out, keeping the skin under the positioning hoop 2 dry and preventing sweating and infection of the wound.

[0025] A positioning block 5 is fixed to the other end of the connecting rod 7. The corner of the bottom of the positioning block 5 has a skin-fitting surface. In use, the skin-fitting surface of the positioning block 5 is attached to the skin between the patient's eye and temple. The positioning clamp 2 and the positioning block 5 support and position the components between them. The skin-fitting surface is arc-shaped, which allows it to better match the shape of the area to be fitted, thus enabling the positioning block 5 to be positioned more stably. A protective pad is fixed to the skin-fitting surface. The protective pad is made of materials such as latex, foam, and silicone. These materials are relatively soft and can provide effective protection, making it more comfortable for the patient to wear.

[0026] Two support rods 4 are horizontally installed on the positioning block 5, such as... Figure 1 and Figure 4 As shown, the two support rods 4 are horizontally positioned between the positioning clamp 2 and the positioning block 5;

[0027] To elaborate further, such as Figure 2 and Figure 4 As shown, this embodiment preferably includes a bidirectional screw 9, and a mounting groove is provided on the positioning block 5. The bidirectional screw 9 is horizontally and rotatably installed in the mounting groove, which is located on the left side wall of the positioning block 5. One end of the bidirectional screw 9 passes through the side wall of the positioning block 5 and is fixed with a handle 6. The handle 6 is fixed to the front end of the bidirectional screw 9, and rotating the handle 6 can drive the bidirectional screw 9 to rotate. One end of each of the two support rods 4 is independently inserted into the mounting groove, such as... Figure 1 and Figure 2 As shown, the right ends of the two support rods 4 are independently installed in the mounting groove, and the right ends of the two support rods 4 can move back and forth along the mounting groove. The two support rods 4 are provided with threaded holes that are threaded to the positive and negative threads of the double-acting screw 9. When the double-acting screw 9 rotates, it drives the two support rods 4 to move in opposite directions through the threaded engagement, thereby adjusting the distance between the two support rods 4. This scheme constitutes an adjustment component for adjusting the distance between the two support rods 4. Of course, the adjustment component can also be a sliding rod. The positioning block 5 is provided with a through groove with a communicating function. The sliding rod is horizontally fixed in the through groove. The right ends of the two support rods 4 are provided with through holes for the sliding rod to pass through. Screws for locking the position of the support rods 4 are installed on the ends of the two support rods 4. By pushing the two support rods 4 by hand, the support rods 4 move along the sliding rod. When they move to the appropriate position, the screws are rotated so that the screws press against the sliding rod, thereby locking the moved support rods 4.

[0028] Eyelid supports 3 are fixed to the unconnected ends of the two support rods 4, such as Figure 3 and Figure 4 As shown, the eyelid support 3 has a U-shaped structure, which is mainly used to hold the upper and lower eyelids together. It is the same as the eyelid support structure on the existing eyelid expander.

[0029] A strap 8 is fixed to the positioning clamp 2 and the positioning support block 5. An eye shield 1 is fixed to the strap 8 connecting the positioning clamp 2. The eye shield 1 is made of materials such as cotton, linen, and flexible fibers. The main function of the eye shield 1 is to protect the patient's unoperated eye from damage caused by light, water, surgical instruments, etc., during surgery, thus ensuring the safety of the patient's unoperated eye. In this embodiment, as shown... Figure 2 and Figure 4 As shown, the strap 8 is an ear loop made of elastic band. It is used to fix the entire device by hanging it on the patient's ears. Of course, the strap 8 can also be a long strip that can be fixed by wrapping around the patient's head. The actual fixing method can be determined according to the actual needs.

[0030] In actual use, two eyelid supports 3 are placed on the upper and lower eyelids to open the patient's upper and lower eyelids. The positioning hoop 2 is then attached to the patient's nose bridge, and the positioning block 5 is placed on the skin between the patient's eyes and temples. The positioning hoop 2 and the positioning block 5 support and position the two ends of the connecting rod 7 to ensure the stability of the two eyelid supports 3 and prevent them from moving or falling out and affecting the surgical operation. Then, the eyelid expansion device is fixed to the patient's head with two straps 8. During the operation, the doctor can rotate the handle 6 to rotate the bidirectional screw 9. The bidirectional screw 9 drives the two support rods 4 to move in opposite directions through the threaded engagement, thereby adjusting the distance between the two support rods 4. This allows the patient's upper and lower eyelids to be expanded to a degree that the doctor deems appropriate, rather than maintaining the maximum expansion state. This makes the patient more comfortable and avoids injury from excessive eye expansion.
