Patent number: 11638604Abstract: A treatment instrument includes a grasping piece that is openable and closable to a treatment portion, and includes an electrode member. An electrode inclination surface facing a side on which the treating portion is located is provided on an outer surface of the electrode member of the grasping piece, and the electrode inclination surface extends from an inner side to an outer side in a width direction so as to be inclined in a direction away from the treatment portion.Type: GrantFiled: July 18, 2019Date of Patent: May 2, 2023Assignee: OLYMPUS CORPORATIONInventors: Marina Kobayashi, Yuji Hirai, Eiji Murakami, Tadashi Kitayama, Satoshi Miyajiri, Katsushi Ide, Takahito Oshiro

Patent number: 11413059Abstract: An energy surgical instrument includes first and second grasping pieces for grasping a blood vessel. At least one of the grasping pieces is designed to apply treatment energy to a grasped blood vessel. The instrument also includes a processor designed to set a wall thickness of the blood vessel, and a grasping force adjuster designed to adjust a grasping force applied by the first and second grasping pieces. A first grasping force is applied when the wall thickness set by the processor is larger than a predetermined thickness, and a second grasping force, which is larger than the first grasping force, is applied when the wall thickness set by the processor is equal to or smaller than the predetermined thickness. A treatment method includes applying treatment energy to a blood vessel grasped by the first and second grasping pieces of the instrument to seal the blood vessel.Type: GrantFiled: August 15, 2018Date of Patent: August 16, 2022Assignee: OLYMPUS CORPORATIONInventors: Marina Kobayashi, Yuji Hirai, Satomi Sakao, Takeshi Onaga, Kazuhiro Morisaki, Katsushi Ide

Patent number: 10098655Abstract: An ultrasonic treatment instrument includes a vibration transmitting member transmitting ultrasonic vibration toward a first gripper and formed as one piece, and a second gripper movable between a spaced position where the second gripper is spaced apart from the first gripper and a closed position where the second gripper is put in close to the first gripper. The ultrasonic treatment instrument includes an interlocking actuator increasing, by moving the first gripper in interlock with a movement of the second gripper to the spaced position, a spacing distance between the first gripper and the second gripper in accordance with a movement of the first gripper.Type: GrantFiled: April 17, 2017Date of Patent: October 16, 2018Assignee: OLYMPUS CORPORATIONInventors: Satoshi Miyajiri, Kazuhiro Morisaki, Yuji Hirai, Takeshi Onaga, Katsushi Ide

Publication number: 20180153569Abstract: A forceps-type treatment instrument includes an end effector including a pair of clamps. In one of the clamps, a swinger is extended along an extending axis and swings relative to a supporting section around a swing axis extended along a direction intersecting with the extending axis and intersecting with an open and close direction of the clamp. A regulating section regulates movement of the swinger in the direction along the swing axis in at least two portions separated from each other in a direction along the extending axis, and thereby prevents rotation of the swinger around a rotation axis along the open and close direction.Type: ApplicationFiled: February 2, 2018Publication date: June 7, 2018Applicant: OLYMPUS CORPORATIONInventors: Katsushi IDE, Tomoyuki KAGA
