Description

Technical Field

[0001] The utility model relates to the field of medical ophthalmic tools, in particular to an eyelid opening device. Background Art

[0002] A lid opener is a medical device used in ophthalmic surgery to open the patient's eyelids, which is beneficial for expanding the surgical field of view to facilitate the operation. It helps to expand the doctor's surgical field of view and is an indispensable tool for ophthalmic surgery. During myopia surgery and most eye surgeries, in order to prevent blinking, a lid opener is needed to fix the upper and lower eyelids of the eyes; especially during corneal refractive surgery, patients need to cooperate with the doctor and try to keep their "eyes still" and not blink during the operation to achieve better and more perfect surgical results; in addition to surgery, lid openers are also needed to prevent blinking, fixation training, and ophthalmic examinations. The working principle of the lid opener is similar to that of a retractor in surgical surgery. It plays the role of a retractor in ophthalmic surgery by supporting the eyelids. The shape of the eyelid opener is usually V-shaped, U-shaped or Y-shaped, and mainly includes a support arm and an eyelid hook. The rear end of the support arm is combined into one to form a hand-held part, and the front end is two symmetrically arranged eyelid hooks. The eyelid hook is usually a horizontal L-shaped structure, and its vertical part is inserted into the eye socket to fix the eyelid, and the horizontal part is used to limit the depth of the vertical part extending into the eye socket to prevent damage to the eyeball. The rear end of the support arm can be adjusted and locked by a knob. The distance between the arm ends.

[0003] Eyelid openers can be divided into wire eyelid openers, titanium alloy screw eyelid openers, and translational eyelid openers. The current eyelid openers have at least the following disadvantages:

[0004] 1. The wire eyelid opener is low-cost, but the structure is unstable. When the patient closes his eyes forcefully, the distance between the two eyelid hooks will become smaller.

[0005] 2. The titanium alloy screw eyelid opener has two symmetrical transmission rods. The transmission rods are pushed by the screw rods to open the two eyelid hooks. There are many problems. First, the transmission rods will occupy a certain area, which will slightly block the eyes and the surgical field. Second, the transmission rods are connected to the support arms, which are connected to the eyelid hooks. When the support arms are opened, they are at an inclined angle, so that the eyelid hooks pull the upper and lower eyelids to keep them open. Third, bacteria or viruses are easily left at the screw holes of the screw rods, but the screw holes are not convenient for cleaning and disinfection.

[0006] 3. During the use of the translational eyelid speculum, if the operation time is too long, the screws are easy to disengage, causing interference or danger to the ongoing operation; and during the use process, it is inconvenient to adjust the knob. Utility Model Content
