System for controlling a tissue-stapling operation

A method of operating an endoscopic stapler including (a) a staple member with one or more staples and (b) an anvil member, comprising:

• positioning the stapler within a body, the stapler being operably coupled to a controller that includes a first member in fluid communication with a first conduit and a second member in fluid communication with a second conduit, wherein each of the first conduit and the second conduit extends from the controller to a hydraulic chamber of the stapler;
• advancing the first member into a first container to direct a fluid from the first container through the first conduit and into the hydraulic chamber to relatively move the staple member and the anvil member towards one another;
• and
• advancing the second member into a second container to direct a fluid from the second container through the second conduit and into the hydraulic chamber to eject one or more staples from the staple member.

A method of operating an endoscopic stapler including (a) a staple member with one or more staples and (b) an anvil member, comprising:

• positioning the stapler within a body;
• rotating a first member to direct fluid through a first conduit to relatively move the staple member and the anvil member towards one another;
• and
• rotating a second member to direct fluid through a second conduit to eject one or more staples from the staple member.
