Description

device for opening eyelids

【Technical field】

The present invention relates to a medical device, more particularly to an eyelid stretcher for ophthalmic surgery and operation, so as to ensure the simplicity and safety of ophthalmic surgery and operation.

【Background technique】

The purpose of ophthalmic surgery and operation is to restore normal visual function, once an intraocular infection occurs, it will bring a devastating blow and catastrophic consequences. Therefore, it is of great clinical significance to reduce the occurrence of infection and ensure the safety of surgery and operation.

The key to ensuring safe operations and procedures is to perform them in a sterile environment. The environment around the eye, such as eyelashes, eyelids, meibomian glands and skin, often contain pathogenic bacteria such as bacteria and fungi, which are the main source of intraocular infection and the culprit that causes intraocular infection, surgery and operation failure. The key to maintaining a sterile environment is to separate the surgical and operating area from the surrounding sterile environment.

Although various simple or complex eyelid speculums have been used in recent years, none of them can solve the above-mentioned problems and achieve the goals of reducing the risk of infection, improving safety, ensuring good curative effect and avoiding waste of medical resources.

Therefore this patent designs a kind of eyelid stretching device for above-mentioned existing deficiency.

【Content of invention】

The purpose of the present invention is to overcome the deficiencies of the prior art, to provide an eyelid stretcher, which can effectively isolate the operation and operation area from the surrounding environment with bacteria, so as to realize the relative aseptic state of the conjunctival sac and ensure ophthalmology. Surgery and manipulations are performed safely.

For above-mentioned purpose, the present invention adopts following technical scheme:

An eyelid stretching device, which is characterized in that it includes a support piece for stretching the eyelids and an adjustment device, the support piece is connected to the adjustment device, the adjustment device includes a connecting piece and an adjusting sleeve, and one end of the connecting piece It is connected with the adjustment sleeve, and the other end is connected with the support piece.

An eyelid stretching device as described above is characterized in that the support sheet is provided with an object sticking part for sticking and isolating eyelids and eyelashes.

The above-mentioned eyelid stretching device is characterized in that the support piece is in the shape of a hook with smooth and blunt edges, and fully and closely contacts with the eyelid after being unfolded.

An eyelid stretching device as described above is characterized in that the supporting sheet is composed of an upper sheet and a lower sheet.

The above-mentioned eyelid stretching device is characterized in that the support piece is configured to fit the eyelid, and the edge is arc-shaped.

The beneficial effects of the present invention are as follows: 1. Completely separate the conjunctival sac from its surrounding eyelids, eyelashes and skin, etc., realize the relative aseptic state of the conjunctival sac, and reduce the possibility of contamination: after the support part is unfolded, it will be connected to the eyelid with a large area. Close contact, and the sticking part is connected with the supporting part, directly sticking to the eyelids or sterile cloth around the conjunctival sac, completely separating the conjunctival sac from its surrounding environment, reducing the continuous pollution of the conjunctival sac by the excretion of the upper and lower meibomian glands and eyelashes during the operation, Increases surgical and operational safety and reduces the possibility of contamination. And completely avoid the eyelashes from entering the operation field, which will affect the operation. At the same time, it also avoids the discomfort and panic caused by the need to cut eyelashes before the operation.

2. High safety: the pasting part surrounds the entire circumference of the conjunctival sac, not only pasting the upper, lower and temporal eyelids, but also pasting the nasal eyelids and bridge of the nose, completely separating the conjunctival sac from the entire surrounding environment, preventing water or disinfectant from flowing to the opposite side , contamination or damage to the fellow eye.

3. High comfort: the reflexed part of the support part is in the shape of a hook, and the edges are smooth and blunt to avoid oppressing the eyeballs and eyelids. According to the radian of the patient's eyelid, the range and range of the eyelid to be stretched can be determined by rotating the adjustment part. The edge of the support part in contact with the eyelids is smooth and blunt, and the area in contact with the upper and lower eyelids is large, which avoids radial compression and cutting force on the eyelids, increases the force-bearing area, and ensures the comfort of the patient.
