Claim 0:
1. A tissue property sensing system, comprising:
an adapter assembly including a drive interface;
a drive screw coupled to the drive interface and extending from the adapter assembly; and
a sensing assembly including:
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 configured to receive the 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 being 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 and occlude blood flow in 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.
