Abstract
The present disclosure relates to devices, systems, and methods for controlling the pressure a sensor applies on the surface of tissue to facilitate locating underlying pressure sensitive critical structures. The laparoscopic device includes a handle and a shaft extending distally from the handle. A flexible member is slidably disposed within the shaft and movable between a retracted position and an extended position. A sensor is coupled to a distal end of the flexible member. The flexible member is configured to flex to limit an amount of pressure applied by the sensor to a tissue surface when the sensor is in contact with a tissue surface.
