Patent number: 9700319Abstract: A surgical stapling device is configured for use in open and/or laparoscopic surgical procedures. The device includes a handle assembly, a shaft assembly coupled to the handle assembly, and an end-effector coupled to the shaft assembly. The end-effector comprises of a jaw assembly configured to clamp, staple, and/or cut a target tissue. The handle assembly comprises of a trigger element that can activate a drive assembly to advance a clamp drive assembly to clamp the aforementioned target tissue. The clamp drive assembly comprises of a clamp slide member to either advance the clamp drive assembly in a first direction or retreat the clamp drive assembly in a second direction. The clamp drive assembly is movably coupled to a clamp driver member. Movement of the clamp driver member operates clamping operations of a jaw assembly of the surgical stapling device.Type: GrantFiled: May 15, 2014Date of Patent: July 11, 2017Assignee: Dextera Surgical Inc.Inventors: Cara C. H. Motooka, Brendan M. Donohoe, Bryan D. Knodel

Patent number: 9655615Abstract: 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.Type: GrantFiled: April 25, 2013Date of Patent: May 23, 2017Assignee: Dextera Surgical Inc.Inventors: Bryan D. Knodel, Philipe R. Manoux, Brendan M. Donohoe

Patent number: 9655613Abstract: A surgical stapling device is configured for use in open and/or laparoscopic surgical procedures. The device includes a staple holder with a first support element and a second support element for supporting a beltless continuous staple chain. Each staple of the staple chain is configured to be frangibly separated from the staple chain to pierce and secure a target tissue when each staple is deployed. The device also includes a plurality of standoff members wherein each of the plurality of standoff members is configured to support one of each staple of the staple chain when the one of each staple is being deployed. The surgical stapling device may be a cartridge-based or a cartridge-less based staple device.Type: GrantFiled: March 12, 2014Date of Patent: May 23, 2017Assignee: Dextera Surgical Inc.Inventor: David T. Schaller
