  • Patent number: 9655615
    Abstract: A surgical stapling device designed and constructed for cutting and stapling tissues in a surgical procedure. The surgical stapling device includes an actuated wedge to deploy staples. The actuated wedge is put into an active state by a first wedge actuation element. In the active state, the actuated wedge is ready to engage and deploy staples in a staple holder. The actuated wedge is put into a neutral state by a second wedge actuation element. In the neutral state, the actuated wedge disengages with the staples and does not deploy the staples. The surgical stapling device includes an I-beam that acts to maintain a clamp gap between the anvil and staple holder of the surgical stapling device to ensure proper stapling of tissue.

  • 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.
