Claim 7:
8. A sensing assembly comprising:
an outer shaft;
an anvil supported on a distal portion of the outer shaft;
a center drive movable within the outer shaft and defining a longitudinal bore, the center drive having a base defining a threaded bore that is configured to receive a drive screw;
a piston movable within the outer shaft and including a distal arm having a distal portion, and a head extending from the distal portion of the distal arm, the piston movable within the outer shaft to move the head in relation to the anvil between an open configuration and a closed configuration, wherein in the closed configuration, the head of the piston and the anvil are positioned to clamp tissue to occlude blood flow in the tissue;
a sensor supported on the head of the piston; and
a tension spring coupled to the center drive and to the piston to urge the piston towards the center drive and to urge the head of the piston towards the anvil.
