Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an eyelid opener for medical eye care. Background Art

[0002] The working principle of the eyelid speculum is similar to that of the retractor, an essential tool in surgical operations. The product itself is a retractor used in ophthalmic surgery in terms of performance. It is called an eyelid speculum because it supports the eyelids during ophthalmic surgery. The eyelid speculum is an indispensable tool in ophthalmic surgery and a special medical device for ophthalmology. Its function is to expand the eyelids, which is beneficial to expand the surgical field of view.

[0003] Publication (Announcement) No.: CN210811249U discloses a medical eyelid opener for ophthalmology. By setting an adjustable eyelid opening mechanism, when medical staff need to adjust the opening angle of the eyelid opener, they only need to loosen the fixing screw. At this time, the spring at the bottom of the eyelid opening arm will bounce the eyelid opening arm to both sides, and the medical staff can use the adjustment bolt to limit the eyelid opening arm, and the eyelid opening arch is fixed to the eyelid opening arm through a fixing groove, and the eyelid opening arch is detachable and replaceable; by setting a fixing mechanism, medical staff can loosen the positioning bolt to adjust the horizontal telescopic rod and the longitudinal telescopic rod according to actual conditions, and after the telescopic rod is adjusted to a suitable position, the positioning bolt can be inserted into the positioning groove to fix it. After completing the adjustment of the telescopic rod, the medical staff can pry open the fixing clamp to make it clamp on the edge of the nursing bed to complete the fixation, freeing the hands of the medical staff.

[0004] The above patent does not have the function of adjusting the height of the eyelid arch, and cannot adjust the height according to the patient's height. The applicable scope of eyelid opening is relatively small, and the distance between the eyelid arches cannot be adjusted, which brings limitations to the eyelid opening operation. Therefore, it is necessary to provide a medical eye care eye opener. Utility Model Content
