Abstract: A system comprises a surgical instrument comprising an end effector comprising a first jaw member and a second jaw member, the second jaw member comprising or being configured to receive a plurality of staples; and an actuation mechanism operably coupled to the end effector to actuate the end effector to perform at least one of a clamping procedure or a staple firing procedure. The system further comprises a drive system configured to drive the actuation mechanism, a controller operably coupled to the drive system, and a user interface operably coupled to the controller, which is configured to determine the clamping procedure or the staple firing procedure has failed based on a magnitude of an actuation force applied by the drive system to the actuation mechanism; and cause the user interface to output a failure indication indicative of the failure.

Abstract: A color-coded surgical table covering or floor mat and/or a surgical color-coded skin marker can be used in a medical setting to identify a bodily location of patient for which a medical procedure is to take place. The surgical color-coded skin marker may be used to mark the location of the medical procedure site on a patient. The medical patient would be oriented to match the surgical table covering or floor mat body form that identifies, through color and orientation, or text, the bodily location of a medical procedure to take place. The combination of the two (table covering/floor mat and skin marker) provides an unmistakable indication that will help limit or reduce wrong-site medical procedures. A surgical mat using a color-coded system or using visual indicia may be used to identify the medical procedure site to medical practitioners, in order to reduce wrong-site medical procedures.
