DOI: 10.1177/0954406216636918
Abstract: Craniotomy is an essential neurosurgical procedure to remove a section of patient’s skull. In order to do this, the surgical tools need to execute a one-degree-of-freedom skull drilling followed by a two-degrees-of-freedom skull cutting. Particularly,… read more here.
