Abstract

A surgical stapling control means has been invented. The control means are contained in a surgical instrument comprising a handle; a trigger pivotally attached and on compression internal to said handle; and staple forming means contained in the forward portion of the handle. The control means comprise a mult-toothed ratchet on the rearward portion of the trigger; at least one guide pin attached to the initial end of the ratchet; a nonpivoting pawl attached to the rearward portion of the handle to coordinate with the ratchet; guide means adjacent the rearward portion of the handle to coordinate with and provide tension to the guide pins. On partially compressing the trigger, the guide means provide tension on the guide pins and the ratchet engages the pawl. On completely compressing the trigger, the guide pins cross over the top of the guide means causing the ratchet to be disengaged from the pawl.
