Publication number: 20230320793Abstract: A surgery system includes: an imager capturing an image of a treatment target; a display having a screen displaying the image of the treatment target captured by the imager; and a processor configured to control a display area of the treatment target on the screen, wherein the processor is configure to: calculate a position of a resection end section of the treatment target on the basis of the image of the treatment target acquired by the imager; cause the display area of the treatment target to be moved to a position at which the resection end section is disposed at a prescribed reference position on the screen; calculate an orientation of a marking added to the treatment target on the screen; and cause the display area of the treatment target to be rotated to an orientation in which the marking is disposed in a prescribed reference orientation on the screen.Type: ApplicationFiled: June 14, 2023Publication date: October 12, 2023Applicant: OLYMPUS CORPORATIONInventors: Masaru YANAGIHARA, Ryota SASAI, Masafumi HARAGUCHI

Publication number: 20230180995Abstract: A medical system includes an endoscope that captures an image including an object, a moving device that includes a robot arm and that moves the endoscope in a body, and a controller that controls the moving device on the basis of the position of the object. The controller is configured to control the moving device in a first control mode in which the endoscope is caused to follow the object at a first speed and a second control mode in which the endoscope is caused to follow the object at a second speed lower than the first speed. The controller controls the moving device in the first control mode when the object is located outside a predetermined three-dimensional region set in a field of view of the endoscope. The controller controls the moving device in the second control mode when the object is located in the predetermined three-dimensional region.Type: ApplicationFiled: February 3, 2023Publication date: June 15, 2023Applicants: OLYMPUS CORPORATION, National Cancer CenterInventors: Hiroyuki TAKAYAMA, Ryota SASAI, Masaru YANAGIHARA, Chiharu MIZUTANI, Hiro HASEGAWA, Daichi KITAGUCHI, Nobuyoshi TAKESHITA, Shigehiro KOJIMA, Yuki FURUSAWA, Yumi KINEBUCHI, Masaaki ITO

Publication number: 20230180996Abstract: A controller controls an image that is captured by an image sensor of an endoscope and is displayed on the display screen of a display device. The controller includes a processor. The processor acquires a first image that is an image captured by the image sensor, detects a first angle of a surgical instrument, and generates a second image rotated with respect to the first image on the basis of the first angle and a predetermined target angle. The first angle is an angle formed by the surgical instrument in the first image with respect to a predetermined reference line that is set with respect to a plane of the first image. A second angle formed by the surgical instrument in the second image with respect to the predetermined reference line is equal to the predetermined target angle.Type: ApplicationFiled: February 3, 2023Publication date: June 15, 2023Applicants: OLYMPUS CORPORATION, National Cancer CenterInventors: Mingxuan DAI, Ryota SASAI, Hiro HASEGAWA, Daichi KITAGUCHI, Nobuyoshi TAKESHITA, Shigehiro KOJIMA, Yuki FURUSAWA, Yumi KINEBUCHI, Masaaki ITO

Publication number: 20230172675Abstract: A controller controls a movement of an endoscope to cause the endoscope to follow a surgical instrument. The controller includes a processor. The processor acquires position information including the position of the surgical instrument, acquires scene information associated with a procedure scene to be observed through the endoscope, determines an offset parameter, which determines the position of the target point with respect to a predetermined fiducial point in the field of view of the endoscope, of a target point on the basis of the scene information, sets the position of the target point with respect to the fiducial point on the basis of the offset parameter, and causes the endoscope to follow the surgical instrument such that the surgical instrument is disposed at the target point, by controlling a movement of the endoscope on the basis of the position of the target point and the position of the surgical instrument.Type: ApplicationFiled: February 3, 2023Publication date: June 8, 2023Applicants: OLYMPUS CORPORATION, National Cancer CenterInventors: Hiroto OGIMOTO, Ryota SASAI, Masaru YANAGIHARA, Hiro HASEGAWA, Daichi KITAGUCHI, Nobuyoshi TAKESHITA, Shigehiro KOJIMA, Yuki FURUSAWA, Yumi KINEBUCHI, Masaaki ITO

Publication number: 20230026537Abstract: A medical system includes: an endoscope; an ultrasonic probe; and a control device that is connected to the endoscope and the ultrasonic probe, generates a display image from a captured image acquired by the endoscope, and generates an echo image from an ultrasonic wave acquired by the ultrasonic probe, wherein the control device acquires a first echo image in which a target tissue is displayed on a central axis, acquires a second echo image obtained by scanning a cross section different from the first echo image at a reference position of the ultrasonic probe from which the first echo image was acquired, and compares a central axis of the second echo image with a position of the target tissue in the second echo image.Type: ApplicationFiled: September 7, 2022Publication date: January 26, 2023Applicant: OLYMPUS CORPORATIONInventors: Ryota SASAI, Toshiyuki MORI, Takeaki ISHIZAWA

Publication number: 20200121416Abstract: A medical instrument holder for holding a medical instrument comprising: an adapter connected to a base portion via an arm; and an instrument holding portion configured to be capable of holding the medical instrument and connected to the adapter. The instrument holding portion includes: a positioning portion configured to perform positioning with respect to the adapter when mounted on the adapter; and a rod configured to be connected to the positioning portion and to be inserted into the adapter. The adapter includes: a contact portion to which an upper surface of the positioning portion contacts and which has an opening; a fitting hole configured to communicate with the opening of the contact portion and to extend in an insertion direction of the rod; and a window portion that is open to the fitting hole and is configured so that an insertion state of the rod can be visually recognized through the window portion when the positioning portion contacts to the contact portion.Type: ApplicationFiled: December 23, 2019Publication date: April 23, 2020Applicant: OLYMPUS CORPORATIONInventors: Ryota SASAI, Kazuo BANJU
