Abstract

A surgical system comprises an end effector for operating on tissue and a screen positioned around the end effector. The screen is fluidly coupled with a suction source by a conduit such as a tube. The screen is configured to communicate suction through the screen while preventing tissue from contacting the end effector. The screen is further configured to retract proximally relative to the end effector to thereby expose the end effector.
