摘要：
An implant driver for engaging an orthopedic implant for selective advancement and retraction of the implant. The implant driver includes a first jaw assembly comprising a helical cam surface corresponding with a first direction of rotation. The first jaw assembly is operative to engage, in response to rotation in the first direction, the implant using spherical jaw members disposed in constrictive helical channels. The implant driver includes a second jaw assembly comprising a helical cam surface corresponding with a second direction of rotation. The second jaw assembly is operative to engage, in response to rotation in the second direction, the implant using spherical jaw members disposed in constrictive helical channels. Absent rotation of the first and second jaw assemblies, the spherical jaws may not restrict relative axial movement between the implant and the implant driver to allow for advancement and/or retraction of the instrument relative to the implant.
