Eye speculum convenient to use for medical ophthalmology department

Abstract

The invention discloses an eye speculum convenient to use for the medical ophthalmology department. The eye speculum comprises a wearing cap; a mounting ring is arranged at the bottom part of the wearing cap; connecting rods A are symmetrically hinged to bottom parts of two sides of the wearing cap; a threaded rod is arranged on one side of each connecting rod A; a connecting rod B is arranged at the middle part of the outer side of each threaded rod; through grooves B are formed between two sides of each connecting rod B and two sides of each of connecting blocks, and the through grooves B fit with the mounting ring. According to the invention, with the cooperation of an arc-shaped plate, convex teeth B, mounting blocks, convex teeth A, mounting frames and springs, after spreading plates are clamped into the eyes of a patient, the spreading angle formed by hinge rods A and hinge rods B can be adjusted according to the size of the eyes of the patient, so that the comfort degree during use is improved, the eyes of the patient are prevented from being injured, and meanwhile, the angle after spreading can also be fixed, which prevents that the hinge rods A and the hinge rods B move in the use process to influence the operation of a doctor.

Description

technical field [0001] The invention relates to the field of ophthalmology, in particular to an easy-to-use eyelid opener for medical ophthalmology. Background technique [0002] The full name of ophthalmology is ophthalmology department. Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. The working principle of the eyelid opener is similar to the necessary tool hook in surgery. The performance of the product itself It looks like a retractor in ophthalmic surgery, because in ophthalmic surgery, it plays a role in supporting the production of eyelids, so it is called a lid opener; [0003] Most of the existing eyelid openers can only simply open the upper and lower eyelids, and cannot adjust the opening angle. Because some people have different eye sizes, these can not adjust the opening angle. The eyelid speculum is easy to injure the patient's eyes, which makes the eye condition worse; bec...

Problems solved by technology

[0003] Most of the existing eyelid openers can only simply open the upper and lower eyelids, and cannot adjust the opening angle. Because some people have different eye sizes, these can not adjust the opening angle. The eyelid speculum is easy to injure the patient's eyes, which makes the eye condition worse; because the size of each person's face is different, the distance between the two eyes of each person is also different, and some wearable eyelid speculums cannot correct Its length is adjusted, it is difficult to meet the requirements of each patient, so that the eyelid speculum cannot open the upper and lower eyelids well during eye surgery, resulting in increased difficulty in use; some wearable eyelid speculums are mostly two-fold The two sets are matched together, and at the same time, they cannot be disassembled quickly, which leads to the occurrence of another set of eyelid openers affecting the doctor during monocular surgery, which makes the operation more difficult; when the doctor performs ophthalmic surgery, the doctor needs to use other Lighting equipment, these make the doctor need to wear a surgical light on the head for surgery, and when the doctor performs the operation, the surgical light will follow the doctor's head shaking, thus affecting the operation; since the brace is placed in the patient's eyelid during the operation, If the support plate shakes, it is likely to cause damage to the patient's eyes, and then aggravate the patient's condition
