Patent number: 11925408Abstract: A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.Type: GrantFiled: December 13, 2022Date of Patent: March 12, 2024Assignee: Covidien LPInventors: Scott J. Prior, Brian J. Creston, Christopher M. Meehan, Amy Kung, Ernest A. Addi, Jacob C. Baril, Thomas A. Zammataro, Saumya Banerjee, Ronald L Green

Patent number: 11864815Abstract: An electrosurgical device for cutting tissue includes a body portion and a tool portion extending distally from the body portion. The tool portion defines a longitudinal axis. The tool portion includes a return lead adapted to be electrically coupled to a return terminal of an electrosurgical energy source, first and second electrical insulators disposed on a first surface of the return lead, and an active lead adapted to be electrically coupled to an active terminal of the electrosurgical energy source. The first electrical insulator is disposed distal of the second electrical insulator. The active lead extends through the first and second electrical insulators such that the active lead and the first surface of the return lead define a gap therebetween.

Publication number: 20210106376Abstract: A surgical instrument includes a housing and a motor. An elongated member extends from the housing. An end effector is at a distal end of the elongated member. The end effector includes a jaw member including a guard. The guard has a number of serrations extending from a proximal end of the jaw member to a distal end of the jaw member. The guard defines corresponding pockets between the serrations. The guard is coupled to the motor to induce reciprocation of the guard relative to the blade upon activation of the motor. A blade is recessed within the guard to expose a cutting edge of the blade between the pockets. The pockets engage tissue. A treatment tip is at a distal end of the guard. The treatment tip connects to an energy source. The treatment tip treats tissue upon activation of the treatment tip.Type: ApplicationFiled: October 9, 2020Publication date: April 15, 2021Inventors: Nikolai D. Begg, Ronald L. Green
