Patent number: 10456163Abstract: A device comprises a retractable shaft; a shaft biasing spring; and an actuator button. The retractable shaft is biased away from the actuator button by the shaft biasing spring. A magnetic attracting force is created between the retractable shaft and the actuator button upon actuation of the actuator button. Before actuation, a distance between the actuator button and the retractable shaft is great enough that the magnetic attracting force is less than a biasing force of the shaft biasing spring such that the retractable shaft is biased away from the actuator button. Upon actuation, the actuator button is depressed to make the distance between the actuator button and the retractable shaft sufficiently small such that the magnetic attracting force is greater than the biasing force of the shaft biasing spring to allow the retractable shaft to be biased towards the actuator button.Type: GrantFiled: March 21, 2017Date of Patent: October 29, 2019Assignee: Gyrus ACMI, Inc.Inventors: Michael O'Connor, John Morici, Michael DeRossi, Steve Gaynes

Patent number: 10433897Abstract: A surgical device employs a longevity circuit for preventing operation after a specified time based on safe use expectations. The surgical device delivers a therapy signal via a handpiece having electrodes in proximity to the surgical site. The therapy signal is a high frequency electrical signal delivered from a generator coupled to the handpiece, and activated by a control signal. A therapy circuit established by coupling the handpiece and generator delivers the therapy signal, and is monitored for activation based on a time since a first activation, a number of activations, or an aggregate time of activated intervals. A usage limit defines the activation lifespan, and is employed for monitoring either the therapy circuit or the control circuit, to determine a usage history. Following expiration of a safe usage limit, a longevity circuit in the handpiece disables the handpiece for successive uses, and is independent of a connection to a particular generator.Type: GrantFiled: August 2, 2018Date of Patent: October 8, 2019Assignee: Gyrus Acmi, Inc.Inventors: Michael A. Virshek, Riyad Moe, Richard J. Curtis, David C. Church
