Claim 13:
14. A system for performing a spinal surgery, comprising:
an expandable spinal implant and a surgical tool for inserting and expanding the expandable spinal implant;
the expandable spinal implant extending in a first longitudinal direction from a proximal end to a distal end and comprising:
a first endplate and a second endplate opposite the first endplate;
a sliding frame coupled to a wedge, at least one of the sliding frame and the wedge being coupled to at least one of the first endplate and the second endplate; and
a moving mechanism comprising a screw guide body defining a rotation axis extending in the longitudinal direction and being configured to rotatably support a first set screw and a second set screw therein, the first set screw being operably coupled to the sliding frame and the second set screw being operably coupled to the wedge,
wherein the surgical tool extends in a second longitudinal direction from a proximal end to a distal end, the distal end comprising a circumferential surface configured to rotate either one or both of the first set screw and second set screw,
wherein the moving mechanism is configured to move at least one of the sliding frame and the wedge forward and backward in the first longitudinal direction upon rotation of the first set screw and/or second set screw via the surgical tool such that the first and second endplates expand and contract with respect to one another, and
wherein the sliding frame is further configured to rotate about the rotation axis upon movement of the wedge in the first longitudinal direction to thereby adjust an angle of inclination between the first endplate and the second endplate.
