Technical Field
[0001] This utility model relates to the field of ophthalmic clinical technology, specifically to a lower eyelid injection fixator. Background Technology
[0002] The lower eyelid, a curtain-like tissue covering the palpebral fissure in front of the eyeball, plays a protective role. Patients with lower eyelid injuries usually need to go to the hospital to receive treatment by injecting medication with a syringe. To prevent medical staff from shaking their hands during injection and causing the needle to pierce the eyeball and cause damage, an injection fixator is usually required.
[0003] Currently, most syringe fixators are in use, but because the lower eyelid is in close contact with the eyeball, simply controlling the stability of the syringe when injecting into the lower eyelid area can still accidentally damage the internal structures of the eyeball, making it difficult to ensure injection safety. Therefore, we propose a lower eyelid injection fixator. Utility Model Content
