Abstract: An end effector of a surgical instrument may be equipped with a firing redirect assembly including: a firing carrier; a reaction pulley disposed distally from the firing carrier; a firing cable coupled to a distal end of the firing carrier and wrapping around the reaction pulley and extending proximally past the firing carrier; and a reaction cable coupled to and extending between a distal end of the reaction pulley and a proximal end of an end effector of the surgical tool, the end effector including a cartridge jaw and an anvil jaw pivotably connected to the cartridge jaw at a pivot, where a firing load on the firing cable in a proximal direction causes the firing carrier to translate distally and causes the reaction pulley and the reaction cable to translate proximally, thereby assisting with closing the anvil jaw or assisting with stabilizing an articulation joint of the end effector.
