Abstract

The invention provides an eyelid lifting device and a preparation method thereof. The eyelid lifting device is used to attach to the patient's eyelid area to assist the eyelid lifting action. The device includes a wire (A), a thermostrictive body (B) and a flexible base (C). The flexible base (C) is in the form of a sheet, The wire (A) and the thermostrictive body (B) are arranged on the surface of the flexible substrate (C), the wire (A) is connected with the thermostrictive body (B) and used to supply power to the thermostrictive body (B), and the thermostrictive The body (B) can change the surface area and / or shape when the temperature changes, and further drive the flexible substrate (C) to deform. The eyelid lifting device according to the invention has simple structure and good therapeutic effect. According to the preparation method of the eyelid lifting device of the present invention, a portable eyelid lifting device that meets the size requirements and deformation design requirements can be prepared.

Description

technical field [0001] The invention relates to the field of flexible electronic technology research, and more particularly relates to an eyelid lifting device and a preparation method thereof. Background technique [0002] Congenital ptosis is manifested by partial or complete inability to lift the upper eyelid, causing the lower edge of the upper eyelid to cover the upper edge of the cornea too much, so that the eye fissure of the diseased eye appears smaller than the normal eye fissure. The pathogenic mechanism of congenital upper blepharoptosis is the attenuation or loss of the function of the upper eyelid muscle, which restricts the opening and closing of the upper eyelid, and then causes the patient's eyes to appear deformed. [0003] The levator muscle is located behind the eyeball, and it is difficult to intervene. It is difficult to directly repair this muscle to cure the disease. In medicine, the "wide frontal muscle flap suspension" is often used to treat the dis...
