Instrument for positioning an intervertebral implant for the fusion between two vertebral bodies of a vertebral column

摘要

The present invention relates to an instrument (1) for positioning an intervertebral implant for the fusion between two vertebral bodies of a vertebral column, comprising:
- a handle (3) having a proximal and a distal end;
- a locking shaft (7) extended from the distal end of the handle (3);
- a grasping head (10) at the distal end of said shaft (7).
Advantageously, the locking shaft (7) is cannulated and a stem (15) is hosted inside the cannulated shaft (7) passing through the handle (3);
the stem (15) is free to rotate with respect to the locking shaft (7), or viceversa;
while the grasping head (10) is formed at the distal end of said stem (15) with a couple of prongs or clamps coming close or far one toward the other according to an angular relative rotation of said stem (15) with respect to the locking shaft (7).
The instrument allows to the surgeon to grip a corresponding implant with a simple rotation movement of his hand.
