Abstract
The gripping device (1) enables the introduction and attachment of a set screw (101) within a U-shaped link connector (102) of a polyaxial or monoaxial pedicle screw (103) to immobilize a connecting rod (104) of a osteosynthesis device (100), and includes a locking element (2) which is supported against the link connector (102) making it possible to ensure concentricity between the principal axes of the gripping device (1) and those of the link connector (102) and to ensure that the connecting rod (104) is kept on the inside of the link connector (102); and an element for releasing (3) the gripping device (1) after establishing and screwing the set screws (101) inside the link connector (102).
