Publication number: 20220343503Abstract: A treatment system that includes a treatment instrument to apply a treatment energy to a living tissue from an end effector according to a supplied electric power to incise the living tissue, an imaging device to generate a captured image capturing a state in which the treatment energy is applied from the end effector to the living tissue, and a control device that includes a processor to control operation of the imaging device. The processor acquires the captured image, calculates a temporal change amount based on any one of a predetermined point and a predetermined area in the captured image as a determination value, determines whether incision of the living tissue has been completed based on the determination value, and in response to determining that incision of the living tissue has been completed, execute an instruction to stop supply of the electric power to the treatment instrument.Type: ApplicationFiled: July 7, 2022Publication date: October 27, 2022Applicant: OLYMPUS CORPORATIONInventors: Kenji MATSUKI, Yuto HIRABAYASHI, Shunsuke MATSUI

Publication number: 20220338898Abstract: A treatment system includes a treatment tool, an imaging apparatus, and a control device. The treatment tool is configured to perform treatment on a living tissue by applying treatment energy from an end effector to the living tissue based on supplied electric power. The imaging apparatus captures an image of the living tissue in a state in which the treatment energy is applied from the end effector to the living tissue. The control device includes a processor to control the imaging apparatus by acquiring the captured image, determining whether an abnormality has occurred in the end effector based on the acquired captured image, and executing an instruction to stop supply of the electric power to the treatment tool when determining that the abnormality has occurred in the end effector.Type: ApplicationFiled: July 8, 2022Publication date: October 27, 2022Applicant: OLYMPUS CORPORATIONInventors: Kenji MATSUKI, Yuto HIRABAYASHI, Shunsuke MATSUI

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
