Abstract
The present disclosure relates to surgical fastener applying apparatus, and the application of variable compression to tissue. More specifically, the presently disclosed surgical fastener applying apparatus including a first jaw having proximal and distal ends and including an anvil member, the anvil member extending along a longitudinal axis and including a tissue contacting surface and a second jaw having proximal and distal ends movably coupled to the first jaw, the second jaw including a cartridge member and a channel. The surgical fastener applying apparatus further includes a pair of elastic members positioned between the cartridge member and the channel of the second jaw, the pair of elastic members configured and dimensioned to apply and maintain constant compressive forces to tissue regardless of tissue thickness.
