Abstract
A blade coupling mechanism for a hand-held surgical cutting instrument includes a first coupling member including a first blade-contacting surface and a first outer perimeter sidewall adjacent the first blade contacting surface. It also includes a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member. The second coupling member includes a second outer perimeter sidewall adjacent the second blade contacting surface. The second blade-contacting surface and the second outer perimeter sidewall meet to define an outer edge. The second coupling member including a bore through the second blade contacting surface. The bore and the second blade contacting surface meeting to define an inner edge. Blade-engaging protrusions project from at least one of the first and second blade-contacting surfaces. The protrusions are spaced closer to the outer edge than the inner edge.
