Surgical guidance systems, devices, and methods
Surgical systems and methods for avoiding injury to an anatomical structure are disclosed. According to some aspects, an implantable device configured to emit a detectable field may be attached to the anatomical structure. A proximity sensor may be attached to a distal end of a surgical instrument and may be configured to detect the detectable field. A control unit in communication with the proximity sensor may be configured to use the proximity sensor to determine if the distal end of the surgical instrument is within a predetermined distance of the implantable device. If so, a notification such as a vibration or alarm may be provided to a user of the surgical instrument so that the user can maneuver the surgical instrument to limit or prevent contact with the anatomical structure.
