1. A surgical procedure for treating a tubular organ, said surgical procedure comprising:
- inserting a circular stapler head of a surgical instrument into the tubular organ;
deploying at least one lighted detection member operably supported by the surgical instrument from a retracted position to a deployed position adjacent a wall of the tubular organ;
observing light from the lighted detection member through the organ wall to assess the location of the circular stapler head within the tubular organ;
retracting each lighted detection member into the retracted position;
puncturing through a proximal portion of the tubular organ with a plurality of tissue acquisition members of the surgical instrument;
positioning the punctured proximal portion of the tubular organ adjacent to the stapler head;
severing the punctured proximal portion of the tubular organ from a distal portion of the tubular organ;
inserting an anvil into the distal portion of the tubular organ such that a connection portion of the anvil protrudes proximally out of an open end of the distal portion of the tubular organ;
securing the distal portion of the tubular organ to the anvil;
coupling the connection portion of the anvil to the surgical instrument;
drawing the anvil proximally toward the stapler head such that another portion of the distal portion of the tubular organ and the punctured proximal portion of the tubular organ are adjacent to each other and captured between the anvil and the stapler head;
stapling the another portion and the punctured proximal portion together with staples; and
cutting through the another portion and punctured proximal portion adjacent to the staples.

Abstract
A surgical instrument is disclosed. Various embodiments include an elongated shaft that defines a central axis and has a distal end portion that is configured to operably support a circular staple cartridge therein. At least one detection member may be operably supported within the elongated shaft. Each detection member may have a distal portion that is radially deployable away from the central axis upon application of a deployment motion thereto. The distal end portions may have a bumper or light mounted thereto.
