| description | The invention provides a novel soft magnetic guide wire with deflection performance and a preparation method of the novel soft magnetic guide wire. Silica gel and pre-magnetized neodymium iron boron magnetic powder are mixed and stirred uniformly to obtain a silicone rubber precursor, and air mixed in the silicone rubber precursor is eliminated; injecting the silicone rubber precursor into a hollow cylindrical mold, and simultaneously placing a concentric guide wire in the mold; curing to form a magnetic conducting wire; and coating the PDMS mixed with the curing agent on the contact surface of the cured magnetic conducting wire and the concentric conducting wire. The magnetic conducting wire is placed in the hydrophilic coating solution to be soaked; the magnetic conducting wire is put into a magnetizer to be magnetized; and an ice water machine is used for cooling. According to the magnetic guide wire with the high deflection performance, on the basis that the magnetic guide wire has the properties of super |
