Abstract
Systems and methods are disclosed for harvesting tissue from a donor site. Exemplary embodiments include a first and second conduit through which a flexible saw component is guided. Certain embodiments include a mechanism which facilitates insertion of the flexible cutting member component parallel to the transverse plane and slicing the graft parallel to the coronal plane to extract the graft.
Claims20
A cutting apparatus for cutting tissue, the apparatus comprising
- a base comprising a first end and a second end,
- a hinge disposed on said base between said first and second ends, the hinge allowing the base to pivot at the hinge to move the first and second ends nearer each other,
- a first conduit and a second conduit associated with said first end and second end, respectively, the first and second conduits having a distal end and proximal end;
- and
- a cutting member disposed within the first and second conduits, said cutting member spans between the distal end of the first conduit and distal end of second conduit.
2 more elements
A system comprising
- a robotic arm;
- a harness device associated with the robotic arm;
- a first conduit and a second conduit movably associated with the harness device such that the harness device moves or allows movement of the first and second conduits toward or away from each other;
- and
- a saw component extending within the first and second conduits and associated with the harness device such that the harness device provides motion to the saw component to induce a cutting effect between distal ends of the first and second conduits.
2 more elements
A system comprising:
- a harness device;
- a fixed conduit and a movable conduit associated with the harness device such that a distance between the fixed conduit and movable conduit may be increased or decreased by movement of the movable conduit;
- a lever that controls the distance between the fixed conduit and movable conduit;
- and
- a saw component extending within the fixed conduit and movable conduit and associated with the harness device such that the harness device provides motion to the saw component to induce a cutting effect between distal ends of the fixed and movable conduits.
