A detachment system comprising:

• an end structure of a push rod for a guglielmi detachable coil of, comprising at least one metal wire, at least one first conductive tube, at least one insulator, and at least one second conductive tube, at least one stopper and at least one securing member,
• the at least one insulator connected to both the first conductive tube and the second conductive tube and configured to electrically insulate the first conductive tube from the second conductive tube, the first conductive tube and the second conductive tube assembled coaxially into an integral tubular structure,
• one end of the at least one metal wire electrically connected to the at least one second conductive tube, the metal wire having a proximal section disposed in a lumen of the second conductive tube and being hooked on the at least one stopper,
• wherein the integral tubular structure is configured to be inserted as a whole into a detacher, enabling the first conductive tube and the second conductive tube to respectively establish electrical connections with a positive power supply terminal and a negative power supply terminal of the detacher,
• wherein one end of the at least one metal wire is connected to the at least one stopper, the at least one stopper is implemented as any of a circular ring, a perforated circular tube, a perforated square tube and a perforated ball, the at least one stopper is disposed inside the second conductive tube by gluing, welding or latching,
• wherein the at least one securing member is formed at one end of the second conductive tube, one end of the securing member extends into the lumen of the second conductive tube so as to wrap around one end of each of the stopper and the metal wire, and
• further comprising the detacher, the detacher comprising the positive power supply terminal and the negative power supply terminal,
• the negative power supply terminal forming a negative circuit portion together with the first conductive tube,
