Patent number: 11317960Abstract: A processor of an electric power source device exercises control over a power output before a control switching time point based on a value related to initial impedance, and determines the control switching time point upon detecting that a value related to impedance of a living tissue is at a minimum. The processor sets a set electric-power value of the power output based on a parameter related to controlling the power output before the control switching time point, and performs constant-electric-power control by controlling the power output using the electric-power value at and after the control switching time point.Type: GrantFiled: August 30, 2019Date of Patent: May 3, 2022Assignee: OLYMPUS CORPORATIONInventors: Tsuyoshi Hayashida, Yoshitaka Honda, Norihiko Hareyama, Ko Kawashima, Kenji Matsuki

Patent number: 9603609Abstract: An energy supplier of an ultrasonic treatment system can output an electric power in a first output mode and a second output mode in which the electric power supplied to a drive force generation unit during a unit time is higher than in the first output mode. A controller maintains an output state of the electric power in the first output mode when a judgment section judges that a load on an ultrasonic probe is less than or equal to a threshold, and switches the output state of the electric power to the second output mode when the judgment section judges that the load is more than the first threshold.Type: GrantFiled: July 21, 2016Date of Patent: March 28, 2017Assignee: OLYMPUS CORPORATIONInventors: Ko Kawashima, Hideto Yoshimine
