Abstract
A surgical stapler has a body, a shaft assembly extending distally from the body, and an end effector coupled with a distal end of the shaft assembly. The end effector has a stapling head assembly, an anvil, and a vacuum port. The vacuum port is operable to draw tissue between the stapling head assembly and the anvil. The anvil is operable to move toward and away from the stapling head assembly to thereby capture the tissue drawn between the stapling head assembly and the anvil. The stapling head assembly comprises a plurality of wheel assemblies and staple cartridges. At least one wheel assembly is operable to rotate to thereby move the anvil toward and away from the body. The remaining wheel assemblies are operable to rotate to thereby drive staples through the captured tissue. The body includes user input features operable to drive the wheel assemblies.
