Surgical instruments for engaging tissue to stabilize tissue and facilitate tissue manipulation

A surgical instrument, comprising:

• a shaft assembly including a stationary shaft and a movable shaft slidably disposed within the stationary shaft, the stationary shaft defining a conduit extending therethrough;
• a surgical tool extending distally from a distal end portion of the movable shaft;
• a cup extending distally from a distal end portion of the stationary shaft, the cup including:
• a body including a proximal end portion and a distal end portion, the body defining one or more channels extending from the proximal end portion to the distal end portion thereof;
• an annular rim disposed at the distal end portion of the body, the annular rim defining a plurality of apertures therethrough, each aperture disposed in fluid communication with one of the one or more channels;
• and
• a cap disposed at the proximal end portion of the body, the cap defining a lumen fluidly coupling the one or more channels with the conduit, the cap defining a central aperture configured to slidably receive at least one of the surgical tool or the movable shaft therethrough,
• wherein the movable shaft is slidable relative to the stationary shaft from a retracted position, wherein the surgical tool is disposed proximally of the distal end portion of the cup, and an extended position, wherein the surgical tool extends through and distally from the cup.
