Computer-aided design/computer-aided manufacturing skull base drill

Abstract: The authors have developed a simple device for computer-aided design/computer-aided manufacturing (CAD-CAM) that uses an image-guided system to define a cutting tool path that is shared with a surgical machining system for drilling bone. Information from 2D images (obtained via CT and MRI) is transmitted to a processor that produces a 3D image. The processor generates code defining an optimized cutting tool path, which is sent to a surgical machining system that can drill the desired portion of bone. T… Show more

“…Couldwell et al. (2017) 17 proposed a computer‐aided design/computer‐aided manufacturing system capable of performing cranial and spine drilling operations semi‐automatically with image guidance and real‐time feedback sensors. The system first generated and displayed a 3D reconstruction of the anatomical structure from a set of pre‐operative CT scans on the user interface.…”

“…The robot had a rigid mechanical structure with 5 degrees of freedom (see Figure 4A) which allowed a wide range of drill angles and positions to be achieved as defined by the surgeon. 17,18 The system was tested on cadaveric samples for the translabyrinthine approach. The system completed the bone removal task in 2 min and 30 s within a 1 mm distance from risk structures.…”

“…(Lozano, Gildenberg et al 2009, Elias, Lipsman et al 2016, Lagman, Chung et al 2017 Another promising area concerns robotics in combination with navigation, which can be used for precise and quick execution of certain tasks, such as instrument, electrode or other effector positioning, setting instrumentation, and performance of brain biopsies, endoscopic ventriculostomy, and craniotomies (even complex types like translabyrinthine approach). (Zimmermann, Krishnan et al 2004, Lozano, Gildenberg et al 2009, Lefranc, Capel et al 2015, Couldwell, MacDonald et al 2017) Scaling robot technology is another invention that translates the movements performed by the surgeon on a human scale to a microscopic level. (Hockstein, Gourin et al 2007) There are many examples showing that the relevant technology promises further multiple exciting advances in the field of neurosurgery, some of which may not be even imagined at the moment.…”
