An orthopaedic tool cluster clamp includes a pair of jaws held together and defining a distance therebetween, the jaws being movable relative to one another to adjust the distance; a connector holding the jaws together, with actuation of the connector adjusting the distance between the jaws; a cam base including a ramped portion statically associated with one of the jaws; and a cam lever pivotally connected to the connector about an axis of rotation and held against the cam base. The cam lever defines a profile such that rotating the cam lever along the ramped portion and pivoting the cam lever about the axis of rotation both cause actuation of the connector.

1. An orthopaedic tool cluster clamp, comprising: a pair of jaws held together and defining a distance therebetween, one of said jaws being movable relative to one another to adjust said distance;a connector holding said jaws together, wherein actuation of said connector adjusts said distance between said jaws;a cam base including a ramped portion statically associated with one of said jaws; anda cam lever pivotally connected to said connector about an axis of rotation and held against said cam base, said cam lever defining a profile wherein rotating said cam lever along said ramped portion and pivoting said cam lever about said axis of rotation both cause actuation of said connector. 2. The clamp according to claim 1, wherein said cam base includes a first flat portion and a second flat portion, said ramped portion being between said first flat portion and said second flat portion. 3. The clamp according to claim 2, wherein said cam base includes a bump formed on at least one of said first flat portion and said second flat portion, said bump preventing free rotation of said cam lever along said ramped portion from at least one said first flat portion and said second flat portion. 4. The clamp according to claim 2, wherein said connector includes at least one ledge, said ledge being held against said second flat portion when said cam lever is held against said first flat portion. 5. The clamp according to claim 2, wherein said cam lever includes a cam portion and a lever portion connected to said cam portion, said cam portion being pivotally connected to said connector and held against said cam base, said lever portion having a first end connected to said cam portion and a second end opposite said first end. 6. The clamp according to claim 5, wherein said second end of said lever portion defines an end axis, said distance between said jaws being at a maximum when said end axis is orthogonal relative to said axis of rotation and said cam portion is held against said first flat portion. 7. The clamp according to claim 6, wherein said cam portion includes a flattened portion held against said first flat portion when said distance between said jaws is at said maximum. 8. The clamp according to claim 5, wherein said profile includes a plurality of reliefs formed therein. 9. The clamp according to claim 5, wherein said cam portion defines a maximum width, said distance between said jaws being at a minimum when said cam lever is positioned so that said maximum width is held against said second flat portion of said cam base. 10. The clamp according to claim 1, further comprising a biasing member forcing said cam lever against said cam base. 11. The clamp according to claim 1, wherein said connector defines a second axis of rotation, wherein rotation of said cam lever about said second axis of rotation along said ramped portion causes actuation of said connector. 12. The clamp according to claim 1, wherein said cam base includes at least two holding portions, said ramped portion being between said at least two holding portions. 13. The clamp according to claim 12, wherein said at least two holding portions include at least one flat portion. 14. A cam assembly, comprising: a cam base having a first flat portion, a second flat portion, a ramped portion positioned between said first and second flat portions, and a bump formed on at least one of said first and second flat portions; anda cam lever held against said cam base and having a connection feature defining an axis of rotation, said cam lever defining a profile wherein rotating said cam lever along said ramped portion and pivoting said cam lever about said axis of rotation both cause linear movement of said connection feature, said bump preventing free rotation of said cam lever along said ramped portion from at least one of said first and second flat portions. 15. The cam assembly according to claim 14, wherein said cam lever includes a cam portion and a lever portion connected to said cam portion, said cam portion being held against said cam base, said lever portion having a first end connected to said cam portion and a second end opposite said first end. 16. The cam assembly according to claim 15, wherein said profile includes a plurality of reliefs formed therein. 17. A cam assembly, comprising: a cam base a ramped portion; wherein said cam base includes a first flat portion and a second flat portion, said ramped portion being between said first flat portion and said second flat portion; anda cam lever held against said cam base and having a connection feature defining an axis of rotation, said cam lever defining a profile wherein rotating said cam lever along said ramped portion and pivoting said cam lever about said axis of rotation both cause linear movement of said connection feature;wherein said cam lever includes a cam portion and a lever portion connected to said cam portion, said cam portion being held against said cam base, said lever portion having a first end connected to said cam portion and a second end opposite said first end; andwherein said cam portion defines a maximum width and said connection feature and said first flat portion define a feature separation distance therebetween, said feature separation distance being at a maximum when said cam lever is positioned so that said maximum width is held against said second flat portion of said cam base. 18. The cam assembly according to claim 14, further comprising a biasing member forcing said cam lever against said cam base.
