An external fixing device for minimally invasive spine leverage reduction comprises a main screw rod (1), leverage percutaneous pedicle screws (2) and leverage devices, wherein the leverage devices comprise connecting pieces (3), pushing sheets (4), fixing screws (5) and leverage screws (6). The left end of the main screw rod (1) is movably arranged in a main screw rod hole (31) of the left leverage device and is located through a nut (11), the right end of the main screw rod (1) is fixedly arranged in a main screw rod hole (31) of the right leverage device, and the left leverage device and the right leverage device are identical in structure and are opposite in direction. The leverage percutaneous pedicle screws (2) are arranged in leverage percutaneous pedicle screw holes (33) of the leverage devices through anti-abrasive cannulas (22). According to the external fixing device for the minimally invasive spine leverage reduction, reduction of thoracic waist fractures can be achieved through leverage opening by operating outside the body, skin soft tissue does not need to be cut open, a patient can be off the bed in one to three days after the external fixing device for the minimally invasive spine leverage reduction is relieved, the patient can recover to a movement state before the injury in a short period of time, and the external fixing device for the minimally invasive spine leverage reduction is especially suitable for 60-100-year-old thoracic waist fracture patients.
