| 摘要 | A surgical apparatus, the apparatus comprising: (a) a cutting tool comprising an axial member with a proximal end and a distal end, the axial member characterized by at least two adjacent axial sections, wherein differences between each of the sections are visually discernible when viewed in a projection x-ray image; and (b) a hollow tube adapted for parallel alignment with the cutting tool and selectively axially positionable to be adjacent at least a selective one of said axial sections and block x-ray radiation from at least one of passing through or passing adjacent said selected section so that said projection indicates a relative axial position of said hollow tube and said cutting tool. | ||

| 主权项 | 1. A surgical apparatus, the apparatus comprising: (a) a cutting tool comprising an axial member with a proximal end and a distal end, the axial member characterized by at least two adjacent axial sections which do not form a part of a cutting tip of said tool, wherein differences between each of the sections are visually discernible when viewed in a projection x-ray image, wherein said visually discernible difference results from an outer radial section of reduced radio-opacity; and (b) a hollow tube adapted for parallel alignment with the cutting tool and selectively axially positionable to be adjacent at least a selective one of said axial sections and block x-ray radiation from at least one of passing through or passing adjacent said selected section so that said projection image indicates a relative axial position of said hollow tube and said cutting tool. | ||
