Abstract
The present application provides a tool for minimally invasive surgical procedures. The tool includes a first and second portion where each portion has an outer blade and an inner blade that is slidable along the outer blade. A removable connector connects the first and second portions. When removed, the first and second portions are separated by a gap extending the length of the tool.
Claims19
A tool, comprising:
- first and second outer blades each having a distal end and a proximal end, wherein the first and second outer blades each comprise an attachment mechanism disposed at the distal end for coupling the first and second outer blades to an implant, wherein the first and second outer blades each comprise an alignment bore in the proximal end;
- first and second inner blades each having a distal end and a proximal end, wherein the first and second inner blades each comprise an alignment window in the proximal end, wherein the alignment window of each of the first and second inner blades overlaps with the alignment bore of the corresponding one of the first and second outer blades, and wherein the first inner and outer blades and the second inner and outer blades cooperate to form a channel extending along an entire length of the first and second inner and outer blades;
- and
- first and second turrets, wherein each turret has a lever pivotally coupled thereto, wherein each turret is rotatably positioned in the alignment bore of the corresponding one of the first and second outer blades, wherein each turret comprises a protrusion that is movably positioned in the alignment window of the corresponding one of the first and second inner blades such that rotation of the turret causes movement of the protrusion, and wherein actuation of the lever rotates the turret and causes the first and second inner blades to move relative to the first and second outer blades about and between an unlocked position and a locked position.

A system, comprising:
- a tool having a proximal end and a distal end, the tool comprising a first portion and a second portion spaced from each other to form a channel extending a length thereof, each of the first and second portions comprising:
- first and second arcuate elongate members, a turret, and an attachment mechanism disposed at a distal end of the first arcuate elongate member, wherein the first arcuate elongate member has an alignment bore disposed in a proximal end thereof and the second arcuate elongate member has an alignment window disposed in a proximal end thereof, wherein the first and second arcuate elongate members are positioned such that the alignment window overlaps with the alignment bore, wherein the turret comprises a protrusion and has a lever pivotably coupled thereto, wherein the turret is rotatably positioned in the alignment bore and the protrusion of the turret is movably positioned in the alignment window such that rotation of the turret moves the protrusion, and wherein actuation of the lever rotates the turret and causes the first elongate arcuate member to move relative to the second elongate arcuate member about and between a locked position and an unlocked position;
- and
- an implant comprising corresponding first and second attachment mechanisms to releasably attach to the corresponding attachment mechanism of the first portion and the second portion, respectively.
