Transverse tibia bone moving device

Abstract

The invention provides a tibia transverse bone moving device which comprises a far-side cortical nail, a near-side cortical nail, a moving screw and a locking nut, the near end of the far-side cortical nail is embedded in the near-side cortical nail, and the far end of the far-side cortical nail extends out of the near-side cortical nail and is fixed to tibia far-side cortex in an external thread mode. The near-side cortical nail is fixed to the near-side tibia cortex in an external thread mode, the locking nut is in threaded connection with the end of the near-side cortical nail, one part of the moving screw penetrates through the locking nut to be in threaded connection with the interior of the far-side cortical nail, and the other part of the moving screw is exposed out of the body of a patient. According to the invention, the operation time in the aspect of intraoperative instruments can be greatly reduced, surgical operations except for a moving part are removed, wounds of a patient are reduced, only the tail end of the moving screw necessary for moving is left, the moving operation is implemented, a postoperative incision only needs to be bound up simply, clothes and trousers can be worn normally, the patient can walk by holding a crutch, dressing change and the moving operation are also simple, and great convenience is provided for postoperative nursing work and normal life of the patient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tibia transverse bone moving device. Background technique [0002] Tibial Transverse Transport (TTT) technology originates from the theory of limb regeneration and functional reconstruction founded by Russian medical expert Ilizarov. Under the action of the tension-stress law, tissue regeneration ability is activated and strengthened. By giving a certain stress stretch, bones and their attached muscles, fascia, blood vessels, and nerves will grow synchronously. This technology provides a new direction for the treatment of diabetic foot with lower extremity vascular arterial disease. The current research results preliminarily show that TTT technology can induce the regeneration of microvascular network in the lower extremity of diabetic foot, promote the healing of foot ulcer, avoid amputation, and reduce the overall risk of diabetic foot.

AI Technical Summary

Problems solved by technology

[0003] The surgical plan proposed in the current expert consensus is to use a bone transfer frame to fix and provide a moving force. The surgical operation is more complicated, and the external part of the bone transfer frame is relatively large. The patient cannot wear clothes and walk normally, so he can only rest in bed. Postoperative nursing work and postoperative normal life of patients cause great inconvenience
