Expandable interbody implant and corresponding surgical tool

A system, comprising:

• an expandable implant movable between a contracted position and an expanded position, the implant comprising:
• an expandable body extending from a proximal end to a distal end in a proximal-to-distal direction and extending from a first lateral side to a second lateral side in a widthwise direction, the expandable body being defined by a superior endplate and an inferior endplate that are hingedly connected;
• the superior endplate comprising a first core having screw slot and a distal engagement surface;
• the inferior endplate comprising a second core having a proximal engagement surface;
• and
• a locking screw movable between a locked position and an unlocked position;
• wherein, in the locked position, the locking screw urges the distal engagement surface of the first core against the proximal engagement surface of the second core;
• and
• a surgical tool configured to move the implant from the contracted position to the expanded position and to move the locking screw between the locked position and the unlocked position, the surgical tool being capable of moving the locking screw into the locked position while supporting the implant in the expanded position,
• wherein the surgical tool further comprises:
• a body portion having an aperture extending therethrough;
• a pivotal linkage assembly including a first arm and a second arm;
• a third arm that is fixed relative to the body portion;
• an outer shaft extending through the body portion and having a drive feature at a distal end thereof for rotating the locking screw from the unlocked position to the locked position;
• and
• an inner shaft extending through the outer shaft and having a first thread pattern at an end thereof for drawing the implant towards the surgical tool.
