A surgical instrument is disclosed herein. The surgical instrument can include an end effector comprising a first jaw and a second jaw, a plurality of electrodes positioned within the jaws of the end effector, a flexible circuit comprising a conductive track configured for multiplexed transmission of a plurality of signals to and from the end effector, a control circuit communicably coupled to the plurality of electrodes via the flexible conductor, and a memory configured to store an algorithm configured to cause the control circuit to: receive signals from the plurality of electrodes; determine an impedance based on the signals received from the plurality of electrodes; detect a media positioned between the jaws of the end effector based on the impedance; determine a position of the detected media along the longitudinal axis based on the received signals; and generate an alert associated with the detected media and the determined position.

Devices, systems, and methods for detecting tissue and foreign objects during a surgical operation

A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.
