Embodiment 2

[0048] Embodiment 2 The improvement scheme of the present invention

[0049] See Figure 7, Figure 7A It is a schematic diagram of the disassembled structure of the fixing device in this embodiment.

[0050] This embodiment improves the structure of the eyelid pulling and fixing device, so that the fixing device can properly adjust the tightness of the suture pulling the lower eyelid while suspending the eyelid suture, and fine-tune the area covered by the lower eyelid to prevent The lower eyelid cannot completely cover the cornea caused by hand stretching and adhesive tape fixation alone, so as to prevent damage to the lower eyelid caused by excessive stretching. The structure of the eyelid pulling and fixing device is as follows: the eyelid pulling and fixing device 8 includes a first fixing body 9, a threaded head 10, a fixing nut 11 and a second fixing body 12, and the first fixing body 9 and the third set The ring structure 4 or the fourth ring structure 5 is fixedly co...

Abstract

The invention relates to a head-mounted lower eyelid suspending device for preventing complications after ptosis surgery in the ophthalmology department. The device comprises a head band, wherein Velcro is arranged at the left end and the right end of the head band, so that the two ends of the head band are connected through the Velcro; a first loop structure, a second loop structure, a third loop structure and a fourth loop structure are arranged on a band body of the head band, the loop structures are arranged on the band body of the head band in a sleeving manner, and the loop structures can slide along the band body of the head band without falling off; eyelid traction and fixing devices are arranged on the third loop structure and the fourth loop structure. According to the head-mounted lower eyelid suspending device, a lower eyelid suture can be closely fixed so that the suture cannot loosen during suspension, and the function of shielding and protecting the cornea strictly is realized; the device is convenient to wear, can also be suitable for children and adult patients, pressure bandaging for an affected eye cannot be influenced after an operation, wound dressing after the operation is not affected, and the device is convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical devices, in particular, it is an ophthalmic ptosis operation to suspend the lower eyelid to prevent exposure keratitis, a serious postoperative complication caused by eyelid insufficiency after ptosis surgery. A protective device that is easy to carry and use. Background technique [0002] Ptosis refers to the insufficiency or loss of the levator muscle (innervated by the oculomotor nerve) and Müller smooth muscle (innervated by the cervical sympathetic nerve), resulting in partial or complete drooping of the upper eyelid. In mild cases, part of the pupil is covered, and in severe cases, the pupil is completely covered Covering not only hinders the appearance and affects vision, but also causes severe amblyopia in congenital cases. Existing ocular ptosis correction surgery, whether using frontal muscle strength or levator muscle strength, will cause short-term (within 6 months) or even...
