Abstract
The current modular implant is particularly useful in spinal surgical procedures. The modular implant can be provided with two anchors and a central section.
Claims20
1) A modular spinal implant adapted for implantation into a surgically created cavity;
- the modular spinal implant comprising:
- a) a first endplate, positioned at a first site of the surgically created cavity, including a first outer perimeter sized to correspond with a first longitudinal side of a central section of the spinal implant;
- the first endplate comprising:
- i) a first planar side including a first tongue perpendicular to the first planar side and extending toward the center of the spinal implant, wherein the first tongue is of lesser length than the first planar side;
- ii) a second side opposed to the first planar side;
- the second side comprising grippers adapted to engage the first site;
- iii) opposed first and second curved edges positioned between opposed first and second linear edges;
- the edges extending between the first planar side and the second side, wherein the first linear edge is of lesser length than the second linear edge creating an angled second side relative to the first planar side;
- iv) first and second slots traversing an approximate length of each curved edge;
- b) a second endplate, positioned at a second site of the surgically created cavity, including a second outer perimeter sized to correspond with a second longitudinal side of the central section of the spinal implant;
- the second endplate comprising:
- i) a first planar side including a second tongue perpendicular to the first planar side and extending toward the first tongue, wherein the second tongue is of lesser length than the first planar side;
- ii) a second side opposed to the first planar side;
- the second side comprising grippers adapted to engage the second site;
- iii) opposed first and second curved margins positioned between opposed first and second linear margins;
- the margins extending between the first planar side and the second side, wherein the first margin is of lesser length than the second linear margin creating an angled second side relative to the first planar side;
- iv) first and second slits traversing an approximate length of each curved margin;
- and
- c) the central section connected to the first endplate and the second endplate;
- the central section comprising:
- i) a first groove positioned on the first longitudinal side of the central section and extending inward from the first longitudinal side of the central section;
- the first groove comprising a first gateway, in the first longitudinal side of the central section, providing slidable engagement for the first tongue;
- ii) a second groove positioned on a second longitudinal side of the central section and extending inward from the second longitudinal side of the central section;
- the second groove comprising a second gateway, in the second longitudinal side of the central section, providing slidable engagement for the second tongue, wherein the combination of grooves and tongues secure the central section between the first and second endplates;
- iii) two opposed openings adapted to engage one or more guidewires;
- iv) a female receptacle adapted to engage a surgical tool;
- v) an internal chamber;
- and
- vi) one or more apertures exposing the internal chamber to the surgically created cavity.

7) A modular spinal implant adapted for implantation into a surgically created cavity;
- the modular spinal implant comprising a first anchor positioned at a first site of the surgically created cavity, a second anchor positioned at a second site of the surgically created cavity and a cylindrical-like central section, wherein first and second lengthwise ends of the central section are sandwiched between complementary inward sides of the first anchor and the second anchor anchored to the surgically created cavity:
- a) the cylindrical-like central section comprising:
- i) a first interconnector positioned at the first lengthwise end;
- ii) a second interconnector positioned at the second lengthwise side;
- b) the first anchor comprising:
- i) a first inward side coplanar with the first lengthwise end;
- the first inward side comprising a third interconnector adapted to mate with the first interconnector;
- ii) a second outward side comprising first grippers adapted to engage the first site, wherein the second outward side of the first anchor is slanted relative to the first inward side;
- iii) at least two curved edges extending between the first inward side and the second outward side;
- and
- iv) first and second slots adapted to receive a surgical instrument distinct from the modular spinal implant allowing the modular spinal implant to be assembled in the surgically created cavity or prior to implantation into the surgically cavity;
- c) the second anchor comprising:
- i) a first inward side coplanar with the second lengthwise end, the first inward side comprising a fourth interconnector adapted to mate with the second interconnector;
- ii) a second outward side comprising second grippers adapted to engage the second site, wherein the second outward side of the second anchor is slanted relative to the first side;
- iii) at least two curved margins extending between the first inward side and the second outward side;
- and
- iv) first and second slits adapted to receive a surgical instrument distinct from the modular spinal implant allowing the modular spinal implant to be assembled in the surgically created cavity or prior to implantation into the surgically cavity.
