  • Patent number: 9566065
    Abstract: A surgical stapling apparatus configured to perform stapling and/or cutting operations on a target tissue of a patient. The surgical stapling apparatus comprises of a mode selection switch to place the apparatus in either a clamping operational phase or a deployment operational phase. In the clamping operational phase, various clamp components are operated to facilitate loading of surgical staples into the stapling apparatus, if not preloaded, placement of the stapling apparatus to a target surgical site, and clamping of target tissue to be stapled and/or cut. In the deployment operational phase, various deployment components are operated to staple and/or cut the target tissue to one or more desired distance intervals to achieve the desired outcome for the surgical procedure.
