Title:
BIONIC DESERT BEETLE SELF-TRANSPORTING BONE MICROGRINDING HEAD AND MANUFACTURING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/246034
Kind Code:
A1
Abstract:
A bionic desert beetle self-transporting bone microgrinding head and a manufacturing process therefor, which relates to the field of medical instruments. The bionic desert beetle self-transporting bone microgrinding head comprises a hydrophobic substrate or a substrate with a hydrophobic coating. The substrate has a hydrophobic surface, and a plurality of hydrophilic abrasive grains are uniformly distributed on the hydrophobic surface; the manufacturing process for the microgrinding head comprises: selecting diamond abrasive grains, and carrying out oxidation treatment on the diamond abrasive grains; scanning a surface of a substrate by laser to form a hydrophobic substrate; alternatively, obtaining a hydrophobic coating by a chemical modification method; and combining the oxidized diamond abrasive grains with the hydrophobic substrate or the hydrophobic coating by electroplating to obtain the microgrinding head capable of capturing cooling medium droplets. By designing the microgrinding head, the microgrinding head can use the combination of hydrophilicity and hydrophobicity to achieve the function of rapid cooling, etc., and can capture and efficiently transport cooling medium droplets to a grinding arc zone.
