Abstract
The invention belongs to the medical equipment category, and particularly relates to a minimally invasive system for a thoracolumbar posterior. The minimally invasive system is characterized by comprising a working channel used for expanding the surgical approach, a positioning template for positioning the minimally invasive cut, a reset sleeve for opening a disease vertebral space, a connecting rod for implanting a screw and rod system, and a rod holder for clamp the connecting rod. Taking the posterior approach, with the help of a C-arm X-ray machine, by using the positioning template, the accurate positioning can be achieved; by using a positioning needle in the working channel, the quick positioning is realized; by the successive expansion of the sleeve, the nail-planted position is exposed; after implanting the connecting rod into the screw and rod system, the disease vertebral space is opening by the reset sleeve, and then is restored to the original place. The minimally invasive system is used for the thoracolumbar posterior, the C-arm X-ray machine is only used in the process of template positioning, so that the operative time is shorter, the incision recovers is quicker, the amount of X-ray is small, the manufacture is simple, the usage is flexible, results are satisfactory and patients' suffering is reduced.
