The invention provides a method for manufacturing multiple strands of spring guide wires. The method comprises the following steps that multiple strands of metal wires are taken and arranged in sequence; one strand of metal wires is additionally taken as an inner core; the ends of the multiple strands of metal wires are fixed to the inner core; and the multiple strands of metal wires are wound on the inner core at the same time, relative motion between the multiple strands of metal wires and the inner core is screw motion, and the multiple strands of screw spring guide wires are formed on the inner core. The multiple strands of metal wires are wound on the inner core at the same time, relative motion between the multiple strands of metal wires and the inner core is screw motion, and therefore compared with guide wires manufactured through a single strand of metal wires, processing time is shortened. Particularly, the time consumed by manufacturing of the guide wires through two strands of metal wires is half of that consumed by manufacturing of the guide wires through a single strand of metal wires, the time consumed by manufacturing of the guide wires through three strands of metal wires is 1 / 3 of that consumed by manufacturing of the guide wires through a single strand of metal wires, processing efficiency is improved, and processing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of guide wire production, in particular to a method for producing a multistrand spring guide wire. Background technique [0002] The guide wire is an important part of medical equipment, especially in the aspects of brain pacemaker and cardiac pacemaker. The guide wire conducts the pulse of the pacemaker to the brain or heart, so as to treat or alleviate special brain and heart diseases . With the advancement of human medical technology, the application of advanced medical equipment will become more and more extensive, and the market for its key spare parts guide wire will also become more and more extensive. At present, the guide wires in the prior art are mostly made in the form of single-strand helical winding. [0003] However, the guide wire in the prior art is made by winding a single strand of metal wire, so the processing efficiency is low and the processing cost is high. Contents of the inventio...
