Abstract
The invention provides a zebra guide wire which comprises a guide wire head and a transmission spindle which are sequentially connected. Each of the guide wire head and the transmission spindle comprises a metal core, and the outer side of the metal core of one end disconnected with the transmission spindle of the guide wire head is provided with a developing spring. The surface of the guide wire head is provided with a polymer casing pipe, and the surface of the polymer casing pipe is coated with a hydrophilic coating. The transmission spindle also comprises a polytetrafluoroethylene coated layer arranged on the surface of the metal core, and the surface of the polytetrafluoroethylene coated layer is provided with spiral stripes which are not in the same plane. As the surface of the metal core of the transmission spindle of the zebra guide wire is coated with the polytetrafluoroethylene coated layer, the controllability is increased, and meanwhile a lower friction coefficient is obtained. The surface of the guide wire head is provided with a polymer precoated with a hydrophilic membrane, so that during use, the friction force between the guide wire head and other instruments or blood vessels can be reduced, therefore the zebra guide wire has the ultra-smooth guide wire head and the transmission spindle with the low friction coefficient and controllability.
