Abstract:
An energy treatment instrument includes: an insertion section in which. a longitudinal axis is defined, a probe, an output section, and a detector. The probe is provided on a distal side along the longitudinal axis of the insertion section and is configured to be pierced into a biological tissue. The output section is provided on the probe and is configured to output energy to an outside of the probe when supplied with energy. The detector is configured to recognize presence of an organ which is located farther than an end portion of the probe, when the probe is pierced into the biological tissue.
Abstract:
A scanning type endoscope includes a light guide section configured to guide illumination light, a ferrule provided along the light guide section, an actuator configured to vibrate the ferrule to thereby swing a distal end of the light guide section, a cylindrical member configured to include a space containing the light guide section, the ferrule and the actuator and being provided along the light guide section, and a damping section configured to fix the ferrule to the cylindrical member and absorb vibration of the ferrule, in which the damping section is formed of a ferrule holding member configured to hold a proximal end of the ferrule and a ring-shaped member configured to fix the ferrule holding member to the cylindrical member, be disposed near a joint in the cylindrical member connected to holding member and be made of a material that absorbs vibration of the ferrule.
Abstract:
A scanning endoscope includes: an optical fiber that guides illuminating light and emits the illuminating light from a distal end; an actuator for swinging a distal end of the optical fiber; a first tubular member that encloses a distal end of the optical fiber and the actuator; a holding portion that holds the optical fiber so that a distal end of the optical fiber is swung by the actuator; a second tubular member that encloses the first tubular member; a fixing portion that is disposed in an area perpendicular to a longitudinal direction of the optical fiber, the area being aligned with a position where the holding portion is disposed, and fixes the first tubular member to the second tubular member; and a distal end fixing portion that is provided at a distal end of the first tubular member.
Abstract:
A scanning endoscope includes an optical fiber that illuminates a living body, a holding member that holds the optical fiber, in which the optical fiber is provided so as to extend from a distal end face by a predetermined length, and a concave portion that communicates with the insertion hole is formed on the distal end face, a drive portion that is provided in the holding member, and causes a free end of the optical fiber that extends from the distal end face of the holding member to scan, and an adhesive portion that is coated on or filled in the concave portion to firmly fix the optical fiber and the holding member to each other, and has a plane which is flush with the distal end face of the holding member formed thereon.
