- 摘要：
PROBLEM TO BE SOLVED: To disclose a coiled structure for medical treatment, medical treatment instrument, etc. that utilize a coil connection method as the technical task of not deteriorating by thermal effects but improving the mechanical strength properties of metal wires of the coil or coil structure used for medical treatment, when a connection is formed on the coil body in part using a connector attached to the coil body or when a connection by the connector is formed in part between the coiled structure for medical treatment and a connection cap.
SOLUTION: The metal wire of coil structure for medical treatment undergoes a strong wire drawing processing of an austenite stainless steel wire and then a winding or twisting processing for the manufacture of a connector material. With attention paid to the temperature and tensile yield strength properties of the high-treated austenite-based stainless steel wire, a connector material is used to form this connector, where its fusion temperature agrees with the temperature to improve its tensile yield strength. Thus the tensile yield strength of metal wire of the coil structure for medical treatment is more improved at the connector.
