Curved spacer and inserter

An instrument for inserting an intervertebral spacer, the instrument comprising:

• an elongated body comprising a proximal end, a distal end and a first passage extending from the proximal end to the distal end, the distal end including a first curved surface opposite a second curved surface and a circular bore disposed between, wherein the first curved surface and the second curved surface together correspond to a shape of a proximal end of the intervertebral spacer;
• a handle coupled to the proximal end of the elongated body, the handle comprising a proximal end, a distal end, and a second passage extending from the proximal end to the distal end;
• a rod receivable through the first passage and the second passage, the rod movable relative to the elongated body and the handle, the rod having a distal end that is removably coupleable to the intervertebral spacer;
• and
• a locking mechanism disposed adjacent the handle, the locking mechanism adapted to tension the rod in a proximal direction in a first position and release tension on the rod in a second position, wherein the locking tab further includes a cylindrical body including a first biasing member and a second biasing member configured to operate as a living spring to apply tension to the rod.

• a handle coupled to the proximal end of the elongated body, the handle comprising a proximal end, a distal end, and a second passage extending from the proximal end to the distal end;
• an attachment system receivable through the first passage and the second passage including a distal end extending from the circular bore to couple the intervertebral spacer to the instrument for insertion;
• and
• a locking mechanism to lock the proximal end of the intervertebral spacer against the curved surface when the locking mechanism is in a first position, and to release the proximal end of the intervertebral spacer from the curved surface in a second position, wherein in the second position the intervertebral spacer remains coupled to a portion of the attachment system, and wherein the locking mechanism includes a locking tab disposed within a locking slot in the handle and the locking tab includes a cylindrical body including a first biasing member and a second biasing member configured to operate as a living spring to apply tension to a rod couplable to the intervertebral spacer.
