1. A surgical instrument for assessing a mechanical property of tissue under compression comprising:
a handle portion;
a body portion extending distally from said handle portion;
a tool assembly extending distally from and operatively connected to said body portion and comprising:
a first jaw member having a tissue supporting surface; and
a second jaw member having a tissue contacting surface, pivotally engaged with each other for pivotal motion about a pivot mechanism to open and close when operated by said handle portion to capture and compress said tissue, and together defining a gap distance there-between;
a force gauge assembly comprising a force transducer and a compression head having a tissue compression face; and
a spacer means for mechanically constraining said pivotal motion of said first jaw member and said second jaw member,
wherein said spacer means is disposed at a predetermined position on said tool assembly and configured to mechanically stop said pivotal motion of said first jaw member and said second jaw member to provide a predetermined gap distance there-between with said first jaw member and said second jaw member in closed position.
