Degradable metal cable internal fixation system

The utility model discloses an internal fixing system for a degradable metal cable, and relates to the field of passive implantable medical instruments. The cable inner fixing system is composed of acable and a clamping buckle. The degradable metal cable is formed by spirally twisting M degradable metal cables, and the degradable metal cables are formed by spirally twisting N degradable metal wires. Welding areas or ends are arranged at the two ends of the degradable metal cable; a clamping buckle is arranged at one end of the degradable metal cable; the cable (including an end) and the clamping buckle are made of pure magnesium and magnesium alloy materials, pure zinc and zinc alloy materials and pure iron and iron alloy materials; one end of the degradable metal cable can be provided with a thread guide needle; when the cable is applied to internal fixation, the cable can be automatically degraded and disappeared in vivo without secondary operation to be taken out, long-term immunological rejection is avoid
