1. A device for treatment of an intervertebral space between two adjacent vertebrae comprising:
an intervertebral prosthesis comprising
a first plate having a first edge, a second edge, and a first surface configured for contact with a first vertebra, the first surface disposed between the first and second edges of the first plate, anda second plate having a first edge, a second edge, and a second surface configured for contact with a second vertebra, the second surface disposed between the first and second edges of the second plate; a prosthesis insertion adapter comprising
a first arm comprising a first jaw configured to hold the first edge of the first plate and the first edge of the second plate, and a first tang disposed at an opposite end of the first arm from the first jaw,a second arm comprising a second jaw configured to hold the second edge of the first plate and the second edge of the second plate, and a second tang disposed at an opposite end of the second arm from the second jaw,an articulation between the first arm and the second arm, the articulation disposed between the first jaw and the first tang and between the second jaw and the second tang, anda coupler configured for operationally releasable attachment of the insertion adapter to an implantation tool; and an elongated implantation tool comprising
a prosthesis insertion adapter support disposed at a first end of the tool, the insertion adapter support comprising a connector attachable to the insertion adapter coupler, andan operating handle disposed at a second end of the tool, the operating handle comprising a control operable to release the connector from the insertion adapter coupler; the device having
an unassembled configuration in which the prosthesis is gripped by the first jaw and the second jaw, the coupler is detached from the connector, and the implantation tool is detached from the insertion adapter, andan assembled configuration in which the prosthesis is gripped by the first jaw and the second jaw, the coupler is attached to the connector, and the implantation tool and the insertion adapter are connected. |
