Background
With the improvement of the living standard of people, the incidence rate of diabetes and peripheral vascular diseases tends to rise year by year. The cases of limb ischemia, pain and necrosis caused by diseases such as diabetic foot, arteriosclerotic obliteration, thromboangiitis obliterans and the like are more and more common, many patients have amputation or risk of amputation, even more patients have wound surfaces which are not healed after amputation, and the disability rate is extremely high. With the popularization of motor vehicles, motor vehicle accidents are frequent, and the risk of ischemic nonunion of fracture patients caused by the high-energy injury is obviously increased compared with the prior art. It has long treatment period, high cost and poor curative effect.
For limb far-end ischemia caused by vascular diseases, treatment modes such as microcirculation improvement, thrombolysis, thrombus removal, vascular stent and the like are mostly adopted in the past, but most of the treatment modes can only temporarily relieve symptoms, the condition of limb ischemia caused by peripheral vascular diseases is not obviously improved, the current curative effect of ischemic nonunion is required to be improved, and the problem can be really solved only by reconstructing limb tissue microcirculation.
In recent years, the proposed technique of lateral bone migration based on the "tension-stress principle" of Ilizarov has become a focus of research and has achieved significant success in the treatment of such diseases. Saves many limbs and functions which need to be cut off in the past. But the defects of complex structure, large operation wound, fracture risk, high difficulty of postoperative care and the like are gradually shown. For example, chinese utility model patent CN203873847U discloses a "tibia transverse bone moving technology treatment auxiliary device", its disadvantages are: the fracture of the tibial shaft needs to be artificially caused by an operation, the fracture block is cut out to be transversely moved to stimulate the proliferation of the vascular network, the structure is complex, the cost is high, the nursing is inconvenient, and the infection rate and the fracture risk are high; further, as disclosed in chinese invention patent CN108498149A, "a titanium cable traction bone moving device and its using method", it has the following disadvantages: the long bone large-section bone defect can be treated only by longitudinal bone transportation, and the treatment principle and the transportation mode of the long bone large-section bone defect are not greatly related to the content of the invention; further, as disclosed in chinese utility model patent CN207886266U, a "horizontal bone-moving external fixation frame" has the following disadvantages: the structure is more complex and heavy, the cost is higher, the nursing difficulty is higher, and the action of the postoperative patient is greatly influenced; further, as disclosed in chinese utility model patent CN2460057Y, a "transverse tibial mobilization revascularization procedure implementation device" has the following disadvantages: the structure is complex, the cost is high, the nursing is difficult, and the infection rate and the fracture risk are high; further, as disclosed in chinese invention patent CN109907786A, "a lateral bone transportation device", has the following disadvantages: the structure is complex, the cost is high, the nursing is difficult, and the infection rate and the fracture risk are high; for another example, chinese utility model patent CN203183002U discloses a "bone-moving microvascular network regeneration device", which has the following disadvantages: complex structure, high cost, difficult nursing, high infection rate and high fracture risk. Further, as disclosed in chinese design patent CN304921104S, a "lateral bone moving rack" has the disadvantages of complex structure, high cost and difficult nursing.
