Instruments for installing multi-section intervertebral spinal implants

An instrument for installing a multi-section spinal implant into an intervertebral space one spinal implant section of a plurality of implant sections of the multi-section spinal implant at a time, the instrument comprising:

• a body having a longitudinal bore extending from a rear opening in the body to a front opening in the body;
• a deployment rod situated in the longitudinal bore and holding a plurality of stacked spinal implant sections;
• a sleeve situated about the deployment rod within the longitudinal bore and having an end that is adjacent an end spinal implant section of the stacked plurality of spinal implant sections;
• and
• a trigger pivotally connected to the body;
• wherein pivotal movement of the trigger advances the sleeve against the end spinal implant section of the stacked plurality of spinal implant sections to deploy a beginning spinal implant section of the plurality of stacked spinal implant sections from the front opening of the body.

An instrument for introducing a multi-section spinal implant into an intervertebral spinal space of a patient, the instrument comprising:

• an elongated body having a longitudinal bore extending from a rear opening in the elongated body to a front opening in the elongated body;
• a deployment rod removably situated in the longitudinal bore and removably holding a plurality of adjacent spinal implant sections of the multi-section spinal implant;
• and
• a cover extending about and axially movable about a portion of the elongated body;
• a wire movably extending through the elongated body, the wire having a first end connected to the cover and a second end extending into the longitudinal bore and adjacent an end spinal implant section of the plurality of adjacent spinal implant sections, wherein movement of the cover moves the wire within the elongated body to push against the end spinal implant section of the plurality of adjacent spinal implant sections to deploy a beginning spinal implant section of the plurality of stacked spinal implant sections from the front opening of the elongated body.

• and
• a sleeve situated about the deployment rod within the longitudinal bore and having an end that is adjacent an end spinal implant section of the adjacent plurality of spinal implant sections, the sleeve having a plurality of longitudinally arranged sleeve teeth on one side thereof;
• and
• a trigger pivotally connected to the elongated body and having a plurality of trigger teeth;
• wherein pivotal movement of the trigger provides engagement of trigger teeth with sleeve teeth to advance the sleeve against the end spinal implant section of the adjacent plurality of spinal implant sections to deploy a beginning spinal implant section of the plurality of adjacent spinal implant sections from the front opening of the elongated body.
