Description

Novel eyelid retractor

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a novel eyelid retractor.

Background

Glaucoma is the first irreversible blinding eye disease worldwide. Despite the continued development of glaucoma medications, surgery still plays a central role in the treatment of glaucoma. Most glaucoma surgery principles are that aqueous humor which cannot be discharged through a normal outflow channel and accumulated in an eye flows out of the artificial channel to the subconjunctival space through artificially manufacturing a new channel on the eyeball wall, so as to play a role in reducing intraocular pressure, and the surgery is called as filterability surgery (such as trabeculectomy, drainage nail implantation and pressure relief valve implantation).

The success of this type of procedure must rely on the formation of a long-term functional aqueous bleb under the conjunctiva, which is often located above the bulbar conjunctiva or above the temporal. Since this aqueous humor passageway is artificially created, the body always tends to repair this passageway, if the repair is too strong, scarring of the filtered passageway is formed, aqueous humor can no longer flow out of the eye through this passageway, and ocular pressure must rise again. Therefore, clinically, if scarring of the filter passages occurs after the filtering operation, it is generally necessary to inject or needle-dial the wrapped bleb around the bleb above the eyeball with an anti-scarring drug (e.g., 5-fluorouracil) after the operation. When performing the above-described ocular procedure in an outpatient treatment room, we need to place an eyelid retractor in order to better expose the eye.

The traditional common steel wire eyelid retractor has relatively consistent eyelid retraction force on the upper eyelid and the lower eyelid, has the defect of insufficient exposure on the filtering blebs positioned above, and often needs an assistant to retract the upper eyelid by using a drag hook or fully open the eyelid by using an adjustable eyelid retractor, thus the operation can bring obvious discomfort to a patient.

Chinese patent literature: CN201821551262.7, filing date 20180921, patent name: novel eye speculum. The utility model discloses a novel ophthalmology eyelid retractor, including the fixed block, the fixed block is cuboid structure setting, and the one end of fixed block both sides wall articulates there is the second articulated rod that the symmetry set up, and two one side that the second articulated rod is close to each other articulates there is the second push rod that the symmetry set up, slip through connection has the movable rod on the fixed block, and the one end that the movable rod is close to the second articulated rod articulates with the tip of second push rod, the other end of fixed block both sides wall articulates there is the first articulated rod that the symmetry set up, and two one side that the first articulated rod is close to each other articulates there is first push rod.

Chinese patent literature: CN201921518039.7, filing date 20190912, patent name: an eyelid retractor. The utility model discloses an eyelid retractor, including the eyelid retractor, the eyelid retractor includes pressing portion and arch portion, and pressing portion is used for contacting eye tissue, and the arch portion is arched relative to pressing portion, and the eyelid retractor still is equipped with liquid suction portion, and liquid suction portion sets up in the arch portion.

The novel ophthalmic eyelid retractor in the patent document CN201821551262.7 adopts the design of the hinging rod and the pushing rod, has novel structure, is convenient to adjust at different angles, is suitable for different patients, can be effectively fixed after being adjusted in angle, avoids secondary injury of the patient, effectively protects the patient, improves the practicality of the eyelid retractor, and is suitable for popularization; in the eyelid retractor of patent document CN201921518039.7, the design of the pressing part, the arch part and the liquid suction part is adopted, so that various liquids retained in conjunctival sac of a patient are drained to the outside through the liquid suction part in the ophthalmic operation process, and the opening of the liquid suction part is higher than eye tissues, so that the liquid suction part is not in direct contact with the eye tissues, and iatrogenic damage to the eye tissues caused by the liquid suction part in the liquid suction process is avoided. However, there is no report on a novel eyelid retractor for enhancing the opening and closing degree of the upper eyelid with smaller eyelid-opening force, fully exposing the area above the eyeball, facilitating the needle extraction and the anti-scarring drug injection after the glaucoma filterability hand, and being applicable to the treatment operation requiring the full exposure of the area above the eyeball.

In view of the foregoing, there is a need for a novel eyelid retractor that enhances the opening and closing of the upper eyelid with less force to fully expose the area above the eye, facilitates the extraction of the filtered hand for glaucoma and the injection of anti-scarring drugs, and can also be used in therapeutic procedures requiring the full exposure of the area above the eye.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides a novel eyelid retractor which can enhance the opening and closing degree of an upper eyelid by using smaller eyelid-retracting force, fully expose the area above an eyeball, facilitate the needle extraction and the injection of anti-scar medicines after glaucoma filtration and can also be used for the treatment operation of fully exposing the area above the eyeball.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the novel eyelid retractor comprises a U-shaped structure eyelid retractor body made of elastic steel wires, wherein elastic arms are respectively arranged at two sides of the novel eyelid retractor body, and a surrounding elastic structure is arranged at the bottom of the novel eyelid retractor body; the front ends of the elastic arms on the two sides are respectively provided with an arc-shaped stretching frame; the middle part of the arc-shaped opening frame is respectively provided with an arc-shaped bulge.

As a preferable technical scheme, the rear sections of the supporting arms at the two sides of the eyelid retractor body are connected with each other through the inserting piece and the inserting slot; and screws and nuts are further arranged in the hollow-out shape of the inserting piece and the inserting groove.
