Abstract

The invention provides an anti-scratch ultra-slip guide wire, a coating method and coating device thereof, wherein the anti-scratch super-slip guide wire comprises a core wire, the tapered section ofthe core filament is coated in the polymer, the other areas of the core filament are encased in hydrophilic or hydrophobic super-slip sleeves, the heat shrinkage temperature of the super-slippery sleeves is higher than the melting point of the polymer tubes and they partially coincide with the push rod of the core filament. In the coinciding region, the super-slippery sleeves are coated with the polymer and the thickness of the polymer in the coinciding region is smaller than that in other regions of the polymer. The design of the scheme is exquisite, the arrangement of high molecular polymerpipe and super-slip sleeve, the two pipe are partially overlapped and coated, so that the high molecular polymer pipe can be restricted by the super-slip sleeve, the pulling force of the polyurethanepipe coating can be increase by more than 10N, the possibility of the high molecular polymer pipe loosening can be reduced, and the safety can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-scratch super-slippery guide wire, its coating method and coating equipment. Background technique [0002] As emerging medical advances, minimally invasive interventional therapy technology and endoscopic technology have been widely developed in recent years. The process is to super-selectively send interventional medical devices through naturally existing blood vessels or internal lumens under the supervision of medical imaging equipment. It is an important technology and method for diagnosis and treatment that reaches many important organs and parts of the human body, such as the heart, liver, brain, kidney, digestive system, and reproductive system. It has the advantages of no surgery, less trauma, and relatively low medical expenses. [0003] In the process of interventional and endoscopic diagnosis and treatment, the guide wire is an important instrument for guiding va...
