Title:
DEVICE AND METHOD FOR POLISHING INTRAOCULAR LENS BY USING ELECTRORHEOLOGICAL EFFECT
Document Type and Number:
WIPO Patent Application WO/2021/169316
Kind Code:
A1
Abstract:
Disclosed is a device for polishing an intraocular lens by using an electrorheological effect. The device comprises a supporting plate (14), an electric motor (16), a conductive slip ring (18), an outer sleeve (20), a tool shaft (22), a connecting flange (24), an annular electrode (26) and a tool needle (28), wherein the electric motor (16), an outer ring of the conductive slip ring (18), and the outer sleeve (20) are all installed on the supporting plate (14), the electric motor (16) drives the tool shaft (22) to rotate by means of a transmission assembly, and one end of the tool shaft (22) is closely fitted with an inner ring of the conductive slip ring (18), and the other end of the tool shaft extends into the outer sleeve (20); and the connecting flange (24) is installed on the outer sleeve (20), the annular electrode (26) is connected to the connecting flange (24), and one end of the tool needle (28) is connected to the tool shaft (22), and the other end of the tool needle extends out of the annular electrode (26). The tool needle used as a cathode and the annular electrode used as an anode in the device have a good insulation effect and both can be detached and adjusted, such that different polishing requirements can be met, and high-quality deterministic polishing for an aspherical intraocular lens can be completed. Further provided is a method for polishing an intraocular lens by using an electrorheological effect.
