The use method of the nerve root avoiding device for the lumbar vertebra posterior surgery comprises the following steps:
according to the actual conditions of a patient and an operation part, a proper vertical connecting part or an inclined connecting part is selected, and the functional part and the handle are connected to the two ends of the selected vertical connecting part or the inclined connecting part through the clamping pin I, the clamping pin II, the clamping hole I and the clamping hole II; when in use, the small hole is firstly formed on the intervertebral disc, then the handle is held by hands, the functional part is stretched into the corresponding part of the operation on the spinal column, and the reinforcing bulge is clamped into the small hole of the intervertebral disc for fixing; arc surface bulge position outside contact backbone of circular arc recess this moment, the border of circular arc recess will be followed I backs down of the nerve root that stretches out here, and the circular arc recess still will be isolated outside from the root of the nerve root II that here extended away, finally makes the intervertebral disc position that needs to perform the operation be in the circular arc recess, and the nervous tissue on every side is all separated by the circular arc recess, and tissues such as nerve root can not be touched to the operation in-process, play the guard action.
Compared with the prior art, the utility model has the following beneficial effects:
1. the functional part can push the nerve root of the intervertebral disc operation part open, and simultaneously can keep other nerve tissues out of the operation position, thereby avoiding the damage of tissues such as the nerve root and the like during the operation.
2. The device can play a role in reinforcing in the using process through the reinforcing bulges, and displacement is avoided.
3. The utility model can connect the functional part and the handle at different angles through the vertical connecting part and the inclined connecting part, is suitable for different patients and different operation positions, and has stronger applicability.
