A surgical instrument comprising: an inner sleeve including an inner drive with an engagement portion engageable with a socket defined in an inner surface of a head of a bone fastener , and an outer tube engageable with an outer surface of the head , wherein the inner drive and the outer tube define a cavity therebetween for disposal of the head , wherein the outer tube includes a first end including a plurality of arms spaced apart by gaps defined by opposite sidewalls and radially movable relative to the inner drive , wherein the inner drive and the outer tube define a collet ; and an outer sleeve axially translatable relative to the inner sleeve and engageable with the outer tube to dispose the inner drive and the outer tube with the head in a co-axial, capture orientation; wherein the surgical instrument is configured to be disposed in an open orientation such that the outer sleeve is disengaged from the collet , thereby disposing the collet in an open orientation such that the arms are expanded and spaced apart; and when the engagement portion of the inner drive is aligned with the socket of the head and as the head is translated into the cavity , the head pushes against the arms causing the arms to expand around the head to provisionally capture the bone fastener , wherein the surgical instrument is further configured so that axially translation of the outer sleeve along the outer tube causes to collapse the collet and compress the arms to capture the provisionally captured bone fastener , wherein the inner drive and the outer tube are disposed in the co-axial, capture orientation with the head , characterized in that the gaps extend from the first end of the outer tube towards a second end of the outer tube opposite the first end so that, in the open orientation, the gaps of the arms are fully exposed. an inner sleeve including an inner drive with an engagement portion engageable with a socket defined in an inner surface of a head of a bone fastener , and an outer tube engageable with an outer surface of the head , wherein the inner drive and the outer tube define a cavity therebetween for disposal of the head , wherein the outer tube includes a first end including a plurality of arms spaced apart by gaps defined by opposite sidewalls and radially movable relative to the inner drive , wherein the inner drive and the outer tube define a collet ; and an outer sleeve axially translatable relative to the inner sleeve and engageable with the outer tube to dispose the inner drive and the outer tube with the head in a co-axial, capture orientation; wherein the surgical instrument is configured to be disposed in an open orientation such that the outer sleeve is disengaged from the collet , thereby disposing the collet in an open orientation such that the arms are expanded and spaced apart; and when the engagement portion of the inner drive is aligned with the socket of the head and as the head is translated into the cavity , the head pushes against the arms causing the arms to expand around the head to provisionally capture the bone fastener , wherein the surgical instrument is further configured so that axially translation of the outer sleeve along the outer tube causes to collapse the collet and compress the arms to capture the provisionally captured bone fastener , wherein the inner drive and the outer tube are disposed in the co-axial, capture orientation with the head , characterized in that the gaps extend from the first end of the outer tube towards a second end of the outer tube opposite the first end so that, in the open orientation, the gaps of the arms are fully exposed. <EOS>
