Description

Transverse bone moving device

Technical Field

The utility model relates to the technical field of bone moving tools, in particular to a transverse bone moving device.

Amputation has to be performed over time to prevent the spread of necrotic conditions. The medical treatment methods for the diseases include intravenous and arterial ultrasonic thrombolysis, positioning and quantitative anticoagulation thrombolysis, artificial blood vessel bypass of limbs, vascular balloon conduction and other methods for treatment, but the effects and the consequences are not ideal. Such as balloon conduction, can conduct occluded vessels, but there is still the possibility of re-occlusion when the original vascular system is cleared. Bone movement is to cut off the bone at normal site, move active bone pieces at a speed of 1mm per day to treat bone defect, restore bone defect, and restore blood supply to ischemic tissue. Through years of medical practice, according to the mechanism that the marrow cavity is rich in blood circulation and can rapidly form a vascular system, a set of vascular system and terminal capillary blood vessel fusion are regenerated from the tibia marrow cavity in the calf. The new blood vessel has strong activity, and can quickly restore blood circulation, so that the tissue necrosis trend caused by vascular occlusion is relieved to recover. The bone moving device is a key device for assisting in treating the tibial vascular occlusion, and is a simple and scientific bone moving device which is the basis for successful operation treatment.
