1. A surgical device comprising:
a handle assembly including:
a power source;
a motor coupled to the power source; and
a controller configured to control the motor;
a reload including a plurality of fasteners;
an anvil assembly being movable relative to the reload; and
an adapter assembly configured to selectively couple to the handle assembly, the reload, and the anvil assembly, wherein the adapter assembly includes a strain gauge configured to measure strain during movement of the anvil assembly,
wherein the controller is configured to:
control the motor to move the anvil assembly thereby compressing tissue between the anvil assembly and the reload at first speed for a first segment and at a second speed for a second segment, the second speed being slower than the first speed; and
determine a predicted clamping force based on a plurality of measured strain values.
