Claim Text:
1. A torque limiting mechanism for use in a surgical instrument that compresses tissue, comprising: a driven member engageable with an approximating mechanism of the surgical instrument, the driven member having a driven surface; a driving member having a driving surface engageable with the driven surface of the driven member and connected to a clamping actuator of the surgical instrument, the driving member rotatable relative to the driven member, such that the driving surface of the driving member slips relative to the driven surface of the driven member at a predetermined engagement pressure; a biasing spring engageable with the driving member such that the driving member is spring biased into engagement with the driven member; and a torque control selectively adjusting the pressure applied by the driving member to the driven member, the torque control including a hook selectively engageable with the biasing spring, and a slide member operatively coupled with the hook.
