Embodiment Construction

[0013] Such as figure 1 , figure 2 and image 3 As shown, the present invention includes a titanium cable 1 (note: provided with a scale), a special Schanz nail 2 (note: provided with a smooth hollow slideway), a winch 3, and a twisted cable seat 4; a twisted cable seat is installed horizontally outside the body 4. Insert two Schanz nails 2 and 6 percutaneously at the receiving end of the bone transfer (the distal or proximal end of the long bone) as required, and set the twisted cable seat 4 on the tail ends of the two Schanz nails 2 and 6 through the hole 41. Both ends are squeezed and fixed with locking bolts 42 . The cable base 4 is equipped with a winch 3, and the outer periphery of the winch 3 is provided with a turntable 32. One end 12 of the titanium cable is fixed on the turntable 32, and the other end is inserted into the bone marrow cavity through the hollow slideway of the special Schanz nail 2 (Note: 11 is the Schanz nail 2 The titanium cable in the slideway e...

Abstract

The invention discloses a transporting device for titanium cable traction bones. The transporting device comprises a built-in bridging-locking bone fracture plate system and an external fixed winch device, wherein the built-in bridging-locking bone fracture plate system is used for fixing a bone defect region in a bridging manner; the external fixed winch device is percutaneously fixed outside a body through a specially-made Schanz nail and a common Schanz nail at a bone transporting receiving end, the specially-made Schanz nail is provided with a smooth hollow slide way, a titanium cable is placed into marrow through the specially-made Schanz nail and extends towards a bone cutting end, one end of the titanium cable is fixed on a cut movable bone block, and the other end of the titanium cable is externally connected to a winch; and the external fixed winch device is mechanically rotated through an axis center to drive a rotating disc to reel the titanium cable in one direction so as to discontinuously and rhythmically pull the cut movable bone block, thereby realizing bone transport formation.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to a device for treating large segmental bone defects of long bones with titanium cable traction osteogenesis technology. Background technique [0002] Bone defects can be caused by infection, trauma, bone disease and tumor. Bone defects have always been a huge challenge for orthopedic surgeons, and bone transfer technology has been maturely applied to the treatment of long bone defects. [0003] Bone transfer is to cut off the normal part of the bone, move the active bone block by extending the speed of 1mm per day, and make it form a bone with the original normal bone tissue, so that continuous callus will appear in the moved part to form new bone tissue , to fill the original bone defect. [0004] At present, most of the instruments used for bone transfer are external fixation brackets, and the existing external fixation brackets are bulky in design, which is not convenient for p...
