Patent number: 11712286Abstract: In a treatment system, an energy treatment instrument includes a pair of grasping pieces. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a blood vessel grasped between the grasping pieces. A measurement section measures a blood pressure at a site related to the grasped blood vessel. A processor controls output of the electric energy from the energy output source based on a measurement result obtained by the measurement section, and thereby switches an actuation state of the energy treatment instrument between a first mode for coagulating the blood vessel and a second mode for coagulating the blood vessel target that is different from the first mode.Type: GrantFiled: October 25, 2018Date of Patent: August 1, 2023Assignee: OLYMPUS CORPORATIONInventors: Tsuyoshi Hayashida, Satomi Sakao, Tatsuro Yamamoto

Patent number: 10980559Abstract: In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.Type: GrantFiled: December 4, 2018Date of Patent: April 20, 2021Assignee: OLYMPUS CORPORATIONInventors: Kazuhiro Tanaka, Yusuke Takei, Ojiro Kitamura, Akinori Kobayashi, Tatsuro Yamamoto
