Abstract:
1. A lever tool device, comprising: a first lever having a proximal end and a distal end; a second lever having a proximal end and a distal end, the first lever and the second lever being pivotally coupled at a lever pivot; a first bar having a first end and a second end, the first end being pivotally coupled to the first lever at a first lever-bar pivot, the first lever-bar pivot located between the lever pivot and the distal end of the first lever; a second bar having a first end and a second end, the first end being pivotally coupled to the second lever at a second lever-bar pivot, the second lever-bar pivot located between the lever pivot and the distal end of the second lever; a first tool having a first end and a second end, the first end of the first tool being pivotally coupled to said distal end of the first lever at a first lever-tool pivot, the second end of the first tool extending distally of the first lever, the first tool being connected by a fixed pivot to the second end of the second bar; a second tool having a first end and a second end, the first end of the second tool being pivotally coupled to said distal end of the second lever at a second lever-tool pivot, the second end of the second tool extending distally of the second lever, the second tool being connected by a fixed pivot to the second end of the first bar; wherein the first tool and the second tool are a mouthpiece, the mouthpiece having a bite area on their second end, the bite area having an occlusal surface located on a side of the mouthpiece that faces away from the corresponding surface of the other tool, and wherein the first tool, the second tool, the first bar, the second bar, the first lever, and the second lever are of predetermined sizes, and the lever pivot, the first lever-bar pivot, the second lever-bar pivot, the first tool-bar pivot, and the second tool-bar pivots, are predetermined distances apart, the lever device being configured to produce an arcuate path of the first tool and the second tool convex to the lever pivot upon movement of the first lever in relation to the second lever.
