Abstract
A circular stapling device includes a manually operated trigger () that is adapted to allow staple formation to occur prior to cutting of tissue during a single actuation of the firing trigger (). The stapling device () minimizes stretching and movement of tissue during staple formation to improve staple formation. The stapling device () also reduces the amount of force required to move the firing trigger () through a firing stroke by separating the staple formation and tissue cutting functions of the stapling device () to reduce stress on a clinician's hand during actuation of the stapling device ().
