1. A method of replacing a consumable of a surgical tool, comprising:
securing the surgical tool, the surgical tool including:
a drive housing;
an elongate shaft extending distally from the drive housing;
an end effector arranged at a distal end of the shaft and including opposing upper and lower jaws;
a wrist interposing the distal end of the shaft and the end effector; and
a knife assembly including a knife arranged at the end effector and first and second drive members extending from the knife to the drive housing;
uncoupling the end effector from the wrist;
removing the end effector from the wrist while the wrist remains intact;
removing the knife assembly from the end effector, and thereby entirely separating the end effector from proximal portions of the surgical tool;
replacing the consumable of the surgical tool;
reconnecting the knife assembly to the proximal portions of the surgical tool; and
coupling the end effector to the wrist.
