Publication number: 20230233245Abstract: Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclsoed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance is defined as Z g ( t ) = V g t I g t . The control circuit receivs a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis.Type: ApplicationFiled: October 10, 2022Publication date: July 27, 2023Inventors: Cameron R.

Patent number: 11653926Abstract: A surgical stapling instrument includes an anvil and a stapling head assembly. The anvil defines staple forming pockets. The stapling head assembly includes a body, a coupling member, a firing assembly, and a staple deck. The coupling member is configured to actuate relative to the body to thereby acuate the anvil relative to the body. The firing assembly is configured to drive staples against the staple forming pockets of the anvil. The staple deck is defined by an outer arched perimeter and an inner arched perimeter fixed to the body. The staple deck defines staple openings. At least one non-tangential staple opening in the of staple openings extends along a longitudinal axis in a non-tangential relationship with a closest tangent line of the inner arched perimeter or the outer arched perimeter.Type: GrantFiled: August 13, 2021Date of Patent: May 23, 2023Assignee: Cilag GmbH InternationalInventors: Shannon L. Jones, Gregory J. Bakos, Jeffery Bruns, Ryan W. McGhee, Scott A. Jenkins, Laura S. Downing, John E. Feds, Maxwell T. Rockman, John E. Brady, Ravi Patel, Aaron C. Voegele, Austin J. Bridges
