  • Publication number: 20230095197
    Abstract: Adapters for surgical drilling systems, and methods of use, are provided for performing surgical procedures, such as surgical drilling into bony structures, while guided by a conductivity sensing system. The adapters may be configured to be coupled to a surgical drilling tool such as a conventional surgical drill and a drill bit having conductivity sensing capabilities, or a surgical hand tool having conductivity sensing capabilities. The adapters further include a controller configured to receive one or more signal indicative of measured electrical conductivity and/or penetration depth measurement, detect a condition associated with a change of measured electrical conductivity based on the signal, and arrest advancement of the surgical drilling tool responsive to detection of the condition.
