US 2021/0259761 A1 · SELECTIVE RESECTION AND DETECTION OF TISSUE MASS

Abstract

A system includes a cutting portion, an actuator coupled to the cutting portion for moving the cutting portion, a controller coupled to the actuator, and a sensor in communication with the controller. The sensor senses if tissue contacted by the cutting portion has hardness above a threshold. If the hardness is above the threshold, the controller permits cutting of the tissue and if the hardness is not above the threshold, the controller does not permit cutting of the tissue. Conversely, the system can have a mode of operation in which if the hardness is below the threshold, the controller permits cutting of the tissue and if the hardness is not below the threshold, the controller does not permit cutting of the tissue.
