Clamping lockout for linear surgical stapler

Abstract

An apparatus includes a housing, a lockout arm, and a spring, and is configured for use with a linear surgical stapler having a first stapler half with a frame and a clamp lever, and a second stapler half with a latch projection. The lockout arm is rotatable between a lockout position and a bypass position and is biased toward the lockout position by the spring. In the lockout position the lockout arm inhibits a proximal end of the clamp lever in a closed state from coupling with a proximal end of the frame. In the bypass position the lockout arm permits the proximal end of the clamp lever in the closed state to couple with the proximal end of the frame. The lockout arm transitions from the lockout position to the bypass position only when the latch projection is properly captured by the clamp lever in the closed state.
