Claim:
1. A surgical device, comprising: a jaw assembly having a first jaw and a second jaw pivotally coupled thereto, the first and second jaws being configured to engage tissue therebetween; a cutting blade assembly slidably coupled to the first and second jaws and configured such that distal advancement of the cutting blade assembly along the first and second jaws moves the second jaw toward the first jaw into a closed position, and proximal retraction of the cutting blade assembly along the first and second jaws allows the second jaw to pivot away from the first jaw into an open position; and a biasing member coupled to the cutting blade assembly, the biasing member being configured to advance distally along a track to apply a compressive force to the second jaw during initial distal advancement of the cutting blade assembly along a proximal portion of the first and second jaws, and the biasing member further being configured to apply no compressive force to the second jaw during further distal advancement of the cutting blade assembly along a distal portion of the first and second jaws, wherein a size of the track is configured to change as the first and second jaws move towards the closed position, and wherein a width of the pin path is smaller at a point at which the biasing member applies the compressive force to the second jaw than a width of the pin path at a point at which the biasing member applies no compressive force to the second jaw when the jaws are in the closed position.
