Abstract
An end effector of a surgical instrument may be equipped with a staple cartridge selection system, including a load sensing cartridge insertable into a channel of a cartridge jaw of an end effector for assembly therewith, the load sensing cartridge including: a body having a proximal end portion and a distal end portion; an elongated channel within the body between the proximal end portion and the distal end portion; a load sensor disposed within the elongated channel of the load sensing cartridge, the load sensor configured to sense a parameter indicative of a tissue thickness when tissue is clamped between an anvil jaw and the cartridge jaw in the clamped configuration; and a visual indicator configured to display a visual indication based on the parameter sensed by the load sensor.
