摘要： A surgical stapling apparatus having an end effector capable of performing a surgical procedure. The surgical stapling apparatus may include a driving pawl that interfaces with a manually actuatable handle. The driving pawl may have a pawl body with a driving tooth thereon that is configured to interact with an actuation shaft such that, as the manually actuatable handle is actuated, the driving tooth interacts with the actuation shaft to cause the actuation shaft to apply the actuation motions to an elongated body operably coupled to the end effector. When the end effector experiences a firing load that exceeds a predetermined magnitude of firing load, the driving tooth moves relative to the pawl body to disengage from the actuation shaft to prevent further transfer of the actuation motions to the elongated body even though the manually actuatable handle continues to be actuated.

摘要： In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.
