SURGICAL RETRACTOR INCLUDING THREE-DIMENSIONAL (3D) IMAGING CAPABILITY

摘要

A surgical retractor includes a shaft and an end effector extending distally from the shaft. The end effector includes a distal finger extending about at least a portion of a perimeter of a geometric shape and configured to facilitate retraction of tissue. The end effector further includes an ultrasound sensor array including a plurality of ultrasound sensors disposed in spaced-apart relation along the distal finger. Each ultrasound sensor of the plurality of ultrasound sensors is configured to emit an ultrasound wave and receive an echoed wave. The echoed waves received by the plurality of ultrasound sensors are output to be reconstructed to produce a real-time 3D ultrasound video image.
