Problems solved by technology

[0004] 1. During the operation on the eye, the doctor cannot adjust the eyelid speculum with one hand to facilitate the temporary removal of the eyelid speculum so that the patient can blink and prevent loosening
[0005] 2. Can't adapt well to eyelids of different sizes for different people
[0006] 3. The way of opening from the inner side of the eyelid makes it impossible to clean the part blocked by the eyelid opener when cleaning the eyeball, and it will easily cause eye discomfort to the patient due to long-term surgery
[0007] 4. Since the eyelids are opened from the inside of the eyelids, there is a risk of eye damage due to improper operation

Embodiment Construction

[0027] The accompanying drawings are all schematic diagrams of the implementation of the present invention, so as to understand the principle of structural operation. The specific product structure and proportional size can be determined according to the use environment and conventional technology.

[0028] Such as figure 1 As shown, it includes a strap 1, a fixed frame 2, an upper eyelid opening mechanism 4, and a lower eyelid opening mechanism 5, wherein the fixed frame 2 is fixed around the eye to be operated by the strap 1 nested in the head; The upper eyelid opening mechanism 4 of the upper eyelid and the lower eyelid opening mechanism 5 used to open the lower eyelid are installed on the fixed frame 2 and are positioned at the upper and lower positions of the eye to be operated; the upper eyelid opening mechanism 4 opens the upper eyelid more than the lower eyelid opening mechanism 5. Open the amplitude of the lower eyelid; the upper eyelid opening mechanism 4 has the sa...

Abstract

The invention belongs to the field of eye speculum, and particularly relates to an ophthalmology instrument convenient to use, which comprises a bandage, a fixing frame, an upper eyelid opening mechanism and a lower eyelid opening mechanism, the eyelid opening prevention device is fixed to the eye needing to be operated through the annular elastic bandage, so that the two hands of an operator are liberated, and a doctor can temporarily relieve the eyelid opening state in the eye operation process so that a patient can blink and loosen.

Description

technical field [0001] The invention belongs to the field of eyelid speculum, in particular to a convenient ophthalmic instrument. Background technique [0002] The working principle of the eyelid opener is similar to the retractor, an essential tool in surgery. The performance of the product itself is the retractor in ophthalmic surgery. Because in ophthalmic surgery, it plays the role of supporting the production of eyelids, so it is called a retractor. Eyelid organ. [0003] There are many types of existing eyelid opener structures, but basically the upper and lower eyelids are pulled apart from the inside of the eyelids in the up and down direction. This method of opening the eyelids has the following problems: [0004] 1. During the operation on the eye, the doctor cannot adjust the eyelid speculum with one hand, so as to facilitate the temporary removal of the eyelid speculum so that the patient can blink and prevent loosening. [0005] 2. It cannot be well adapted t...
