Publication number: 20210145473Abstract: Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.Type: ApplicationFiled: December 4, 2020Publication date: May 20, 2021Inventors: Stephen E. Eichmann, Karen K. Isaacs, Kenneth S. Kramer, Michael R. Lamping, Ashvani K. Madan, Matthew C. Miller, Aaron C. Voegele, Eitan T. Weiner, Joseph E. Young

Patent number: 10426507Abstract: A surgical instrument including a transducer and an end effector is disclosed. The transducer may be configured to generate an acoustic standing wave of vibratory motion along a longitudinal axis and may include a piezoelectric stack positioned along the longitudinal axis. A length of the transducer may be less than ½ of the wavelength of the acoustic standing wave. The end effector may be acoustically coupled to and may extend distally from the transducer along the longitudinal axis. A sum of the length of the transducer and a length of the end effector may be an integer multiple of ½ of the wavelength of the acoustic standing wave.Type: GrantFiled: September 9, 2016Date of Patent: October 1, 2019Assignee: Ethicon LLCInventors: Eitan T. Wiener, Foster B. Stulen, Michael J. Stokes, Karen K. Isaacs, William J. Kraimer

Patent number: 9439669Abstract: A surgical instrument. The surgical instrument may comprise a transducer and an end effector. The transducer may be configured to provide vibrations along a longitudinal axis at a predetermined frequency and may comprise a piezoelectric stack positioned along the longitudinal axis. The transducer also may comprise a first metallic end mass positioned along the longitudinal axis adjacent a first end of the piezoelectric stack and a second metallic end mass positioned along the longitudinal axis adjacent a second end of the piezoelectric stack. The length of the transducer may be greater than or equal to of one wavelength and less than ½ of one wavelength. The end effector may be coupled to the transducer and may extend along the longitudinal axis. The length of the transducer and the end effector may be a multiple of ½ of one wavelength.Type: GrantFiled: March 28, 2013Date of Patent: September 13, 2016Assignee: Ethicon Endo-Surgery, LLCInventors: Eitan T.
