In breast waist section bursting fracture posterior approach to protruding into resetting of sclerite in the canalis spinalis, need to use certain apparatus to rely on feel to reset, owing to can't under direct-view, reset, be difficult to guarantee the effect that resets, and may push dural sac and nerve root increase the weight of nerve injury because of the decompression operation that resets.Fracture reposition instrument in the existing L type canalis spinalis, not only reset effect is difficult to ensure, and may cause in the art accidental injury to spinal cord or nerve injury, and then causes the ghost phenomenon to cause posterior approach kyphosis deformity at a specified future date.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of C type positor that is applied in the lumbar vertebra compression fracture operation, both can avoid in the art accidental injury to spinal cord or nerve injury, can effectively carry out again resetting in the canalis spinalis of vertebral fracture piece, thereby significantly reduce the incidence rate of the posterior approach kyphosis deformity at a specified future date that the ghost phenomenon causes.
For achieving the above object, technical scheme that this utility model adopts is as follows:
A kind of C type positor that is applied in the lumbar vertebra compression fracture operation, the C type crotch that this C type positor comprises handle, is connected the straight-bar of described handle front end and is arranged on described straight-bar front end.
Further, this utility model has designed large, medium and small 3 kinds of models: wherein, the major diameter of the C type crotch of large size and transverse diameter are respectively 25 millimeters and 16 millimeters; Wherein, the major diameter of the C type crotch of medium size and transverse diameter are respectively 20 millimeters and 13 millimeters; Wherein, the major diameter of Xiao Hao C type crotch and transverse diameter are respectively 15 millimeters and 10 millimeters.
Preferably, described handle, straight-bar and C type crotch are titanium alloy.
Its fore-end of this utility model C type positor is c-shaped, C shape crotch head end is close to the canalis spinalis side and is entered canalis spinalis the place ahead when entering canalis spinalis, it is comparatively easy to enter canalis spinalis, less to spinoneural interference, can effectively avoid spinoneural extruding and unnecessary tractive operation.Its front end C shape partly meets breast waist section canalis spinalis anatomic form, pushing and withstanding canalis spinalis front wall bone folded block collapses into curved in vertebral body, can recover sagittal diameter and the transverse diameter of canalis spinalis to greatest extent, vertebral canal volume is effectively restored, therefore obtain reset effect preferably, for the early recovery of function of spinal nerves has been created good environment.
