A kind of micro guide wire composite core wire preparation device and its preparation method

Abstract

The invention discloses a micro-guide wire composite core wire preparation device and a preparation method thereof, which belong to the technical field of medical devices and include a workbench, a moving device, a fixing device, a composite core wire processing device, a conveying device, a clamping device, and a cleaning device and the micro guide wire processing device, the moving device is set on the worktable, the fixing device is set on the moving end of the moving device, the composite core wire processing device is set on the workbench, the conveying device is set on the workbench, and the clamping device is set on the On the conveying end of the conveying device, the cleaning device is arranged on the workbench, and the micro guide wire processing device is arranged on the workbench. The mobile device transports the composite core wire on the fixed device, the composite core wire processing device straightens and polishes the composite core wire, the clamping device clamps the spring and the composite core wire, and the cleaning device cleans the clamped spring and composite core wire. The core wire is cleaned, and the micro guide wire processing device welds and covers the spring and composite core wire.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a preparation device and a preparation method of a micro-guide wire composite core wire. Background technique [0002] When treating stenosis that occurs in blood vessels such as coronary arteries surrounding the heart or treating areas that are completely occluded in blood vessels due to the progression of calcification (for example, chronic total occlusion: CTO, etc.), it is necessary to place the The guide wires used to guide these instruments are inserted into the blood vessels first, but in the production process of the existing micro guide wires, welding operations are often performed on them during the production of the micro guide wires. In the existing processing equipment, for the During the welding process of the micro-guide wire, the inner core of the micro-guide wire and the spring cannot be accurately butted together, which may cause misalignment during weld...

AI Technical Summary

Problems solved by technology

[0003] The embodiment of the present invention provides a micro-guide wire composite core wire preparation device and its preparation method to solve the problem that the inner core and spring of the micro-guide wire cannot be accurately docked together during the welding process of the micro-guide wire, which may lead to Dislocation occurs during welding, and the surface of the product is not coated after welding, resulting in insufficient elasticity of the product, which affects the technical problems of subsequent use
