Abstract: This invention concerns an automated registration method and device for a surgical robot enabling registration between a first three-dimensional location system comprising an optical distance sensor and a second three-dimensional location system comprising optical acquisition means. The method comprises: a first step of intraoperative registration between the first location system and data recorded on an anatomical surface of a patient and; a second step of intraoperative registration of two three-dimensional location systems. The second registration step is performed at the same time as the first registration step by detection, by the optical acquisition means, of at least one point of a point cloud acquired by the optical sensor during the first intraoperative registration.

Abstract: A side fire optical fiber tip is provided for use in high power laser applications having outputs of greater than or equal to 50 Watts. A predetermined length of an output tip on the distal end of the optical fiber is formed with an optical fiber core and cladding layer of preselected thickness wherein the cladding to core diameter ratio is at least as great as 1.2. A side fire surface is formed on the distal end of the core/clad output end. Over this optical fiber output end, a pure silica capillary tube is fused to the predetermined length of exposed cladding where the outermost cladding is also pure silica to reduce thermal mismatch during the fusion process. By having the refractive index at the fusing interface matched, and bubbles or gaps eliminated or prevented, it is possible to substantially eliminate Fresnel reflection losses at this interface.
