Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic equipment, in particular to an eyelid opener used for ophthalmic examination surgery. Background Art

[0002] In daily life, there are also many accidents where cosmetics or vegetable oil splash into the eyes. The eye nerves are densely distributed. Once injured, they will immediately experience symptoms such as burning pain, foreign body sensation, photophobia, tearing, eyelid spasm and blurred vision. In severe cases, corneal necrosis and blindness will occur. For patients with such chemical burns, eye irrigation is the most critical step in emergency treatment, which has a great impact on the prognosis. The current procedure for flushing the conjunctival sac is to let the patient hold the water receiver close to the cheek on the flushing side of the patient. The doctor then holds saline in one hand and uses the thumb and index finger of the other hand to pry open the upper and lower eyelids to expose the conjunctival sac. The patient is advised to open his eyes as much as possible and move his eyeballs up and down and left and right. However, the disadvantage of this method is that the patient himself is in unbearable pain after the injury and cannot open and move his eyeballs completely as required by the operating specifications. This will cause some chemicals to remain in the dome of the conjunctival sac, leaving hidden dangers, so multiple medical staff are required to cooperate in opening the eyelids.

[0003] To this end, the present application designs a lid opening device for ophthalmic examination surgery, which can be quickly completed by a doctor alone to solve the above-mentioned problem. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Figure 1-Figure 3 This is a specific embodiment of the utility model, which is a lid opener for ophthalmic examination surgery. The eyeglass frame 1 is an eyeglass frame without a nose pad. The upper and lower positions of the frame 101 of the eyeglass frame 1 are movably connected with the lid opener 2. The lid opener controller 3 is installed on one side of the frame 101. The lid opener controller 3 controls the movement of the lid opener 2. Limiting holes 103 are opened at the upper and lower positions of the frame 101 of the eyeglass frame 1. The lid opener 2 is slidably connected in the limiting holes 103. A first wire drawing hole 104 is opened at the upper and lower center positions of the frame 101. A second wire drawing hole 105 is opened at the outer side of the side of the frame 101 near the lid opener controller 3. The first wire drawing hole 104 and the second wire drawing hole 105 are connected along the inside of the frame 101, and the connecting passage avoids the limiting hole 103. The wire drawing 203 of the lid opener 2 is arranged in the passage. The eyelid-opening device 2 includes a support hook 201, and both ends of one side of the support hook 201 are fixedly connected to a limiting column 202, the limiting column 202 passes through the limiting hole 103, and the center of one side of the support hook 201 is fixedly connected to one end of a pull wire 203, and the other end of the pull wire 203 passes through the first pull wire hole 104 and the second pull wire hole 105 and is fixedly connected to the eyelid-opening controller 3. The eyelid opening controller 3 includes a bearing seat 301 fixedly connected to one side of the lens frame 101, a hole is opened in the bearing seat 301 and a bearing 302 is provided, a twisted wire shaft 303 is connected to the bearing 302, a hole is opened at the end of the twisted wire shaft 303, the pull wire 203 is tied to the hole of the twisted wire shaft 303, a hand wheel 304 is fixedly connected to the end of the twisted wire shaft 303, the outer periphery of the hand wheel 304 is engraved with anti-slip grooves, the surface of the hand wheel 304 is grooved, a buckle 305 is hinged on one side of the bearing seat 301, and the buckle 305 is engaged in the groove of the hand wheel 304 to prevent the hand wheel 304 from rotating. The buckle 305 and the surface grooves of the hand wheel 304 are provided with magnets that attract each other.

[0021] The specific usage of this embodiment is as follows:

[0022] After putting the glasses frame 1 on the patient's face, a strap is tied at the end of the temple 102 to prevent the glasses frame 1 from moving. Since there is no nose pad structure, the frame 101 will fit the patient's face, making it convenient for the eyelid opening device to open the eyelid. The support hook 201 is hooked on the eyelid, and the doctor turns the hand wheel 304. The pull wire fixed on the twisted wire shaft 303 will be wound around the twisted wire shaft 303, and the other end of the pull wire will pull the support hook 201 to continuously approach the frame 101 until the eyelid is completely opened. At this time, the buckle 305 is clamped on the hand wheel 304, the twisted wire shaft 303 will no longer rotate, and the support hook 201 will continue to hold up the eyelid.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
