Description
Technical field
The utility model relates to the field of medical instrument technology, more particularly to a kind of slidingtype jointing.
Background technique
For the patient of congenital scoliosis, need to carry out the crooked radian of backbone before bone growth and development is mature
Control influences the development of thorax or even important internal organs otherwise it is possible that their lateral bending degree can become very serious,
Even result in death.For lesser extent and conservative therapy can be implemented in the good patient of backbone flexibility method, branch is such as worn
Tool etc., but to a big chunk patient, then it needs to carry out operation intervention, reduces or slow down the progress of lateral bending angle, make patient
Scoliosis angle development complete before control in a certain range.
Currently used therapeutic method of surgery need to often use much shorter pitmans to connect into a longer growing rod.
After two pitmans are connected into an entirety by the jointing of existing pitman, the growth and fortune of patient centrum often will affect
It is dynamic.
Summary of the invention
Based on this, it is necessary to provide a kind of slidingtype jointing, it is ensured that the correction of patient's coronal-plane and sagittal plane,
And do not limit the growth and movement of patient centrum.
