Abstract: Systems and methods are described herein to generate a 3D surface scan of a surface profile of a patient's anatomy. The 3D surface scan may be generated by reflections of structured light off the surface profile of the anatomy. The 3D surface scan may be used during intra-operative surgical navigation by a localization system. Optionally, a pre-operative medical image may also be registered to the localization system or used to enhance the 3D surface scan.

Abstract: Multi-directional drilling of a bone to create a perforation of bone cortex. The disclosure presents methods of using a drill having a measurement system to advance a drill bit through a bone with detection of penetration or eruption of the leading edge of the drill bit through the exterior of the cortex layer of the bone. In this regard, operation of the drill may be controlled to limit soft tissue damage adjacent to the distal side of the bone. The drill bit may be at least partially retracted through a first bore, repositioned, and one or more additional bores may be created, all while monitoring for penetration of the leading edge of the drill bit relative to the cortical layer. In turn, a perforated distal side of the cortical layer of the bone may be created that creates a desired weakness in the bone, which may be useful in various operations including when performing a corticotomy or the like.

Abstract: A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.
