Description

A kind of multi-segmental tandem Spondylitis ankylosing support
Technical field
The present invention relates to a kind of technical field of medical equipment, more particularly to a kind of multi-segmental tandem Spondylitis ankylosing branch Frame.
Background technology
Thoracolumbar fracture belongs to frequently-occurring disease common disease in clinic at present, and its Surgical Principle is both recovery vertebral height It is stable with spinal biomechanicses, wound is simultaneously reduced as far as possible, recovers function, and it is also spine fracture to improve patients ' life quality Treatment needs the important stabilization considered.Currently in the thoracolumbar fracture of Lumbar spine, the big more options hand of its therapeutic modality Art reduction fixation is treated.But traditional open surgery mode has wound big, bleeding is more, solid in short-segment pedicle instrument screw Determine system stress and block to be easily caused screw loosening, fracture, post-operative corrective degree such as is easily lost at the complication.In addition, neighbouring section Regression is accelerated also to produce influence to late result.
Therefore since Spondylitis ankylosing its applying clinical in 1977, the welcome of numerous clinicians, but tradition have been received There is complicated, cumbersome, the shortcomings of postoperative care is difficult in external fixator.It is hindered in clinical application, though through many The improvement of secondary domestic and foreign scholars, the need for can not still meeting clinic.This current research team has researched and developed New Percutanous External Spinal Fixation And applied to clinic, but this exterior fixing rack is only applicable to the operative treatment of single segmental thoracolumbar fracture, in more segmental thoracic lumbar vertebrae Still there is deficiency on the operative treatment of fracture.For the above-mentioned reasons, it is the current more segmental thoracic fracture of lumbar vertebra conventional therapy of solution Control that treatment trauma is big, costly, the situation more than postoperative complications, while it is small to give full play to Spondylitis ankylosing device wound, biomethanics The good advantage of characteristic, reaches the pain for reducing patient, the purpose for improving late result.Therefore, a kind of it is proposed that multi-segmental Tandem Spondylitis ankylosing support.
