Device and Method for Image-Guided Surgery

摘要

In one aspect the invention provides a reference device that enhances image-guided surgical interventions. The reference device is tracked by the imaging system and used to verify the accuracy of the intervention tool placement before and during the intervention. The reference device holds a reference sensor in a position aligned with patient anatomy, so that images are displayed in the correct orientation to the operator, aiding in target recognition and better navigation. Also provided are methods using the reference device and programmed computer media for implementing at least a part of the methods.

主权项

1. A reference device for surgery, comprising:
a base portion, including; a socket that accepts a tracking sensor in a pre-defined orientation; one or more reference divots that accept at least a portion of a surgical intervention tool, the one or more reference divots being substantially transparent to one or more imaging modalities; and a plurality of anatomical direction markers adapted to provide alignment of the reference device with a patient's anatomy; wherein each anatomical direction marker uniquely corresponds to a standard anatomical orientation in an anatomical coordinate system.
