Methods and systems for directing movement of a tool in hair transplantation procedures

摘要

Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable a tool, such as a hair harvesting or a hair implantation tool, to proceed at least under a partial computer control in a selected direction of travel along a donor or recipient area of the patient, as well as changing direction of travel based on desired harvesting and/or implantation criteria.

1. A method of directing movement of a tool to harvest or implant hair grafts, the method comprising:
recording first locations of a plurality of fiducials appearing in one or more images of a body surface; updating and recording the updated locations of at least some of the plurality of the fiducials in an updated one or more images of the body surface; determining an offset of the updated locations of the at least some of the plurality of the fiducials relative to their first locations; automatically selecting a new follicular unit harvesting or implanting site based at least in part on the determined offset and a location of a previous procedure site; and automatically instructing the tool to move to the selected new harvesting site or the selected new implanting site.
