  • Publication number: 20230320810
    Abstract: A living body compressing clip 100 includes a clip body 1 with metallic arm parts 5a and 5b configured to hold a living body tissue. The clip body 1 includes compressing pieces 10 that protrude from distal end parts of the arm parts 5a and 5b in a long-side direction of the arm parts 5a and 5b. The compressing pieces 10 are formed from a flexible resin and hold a fluorescent dye. According to the living body compressing clip 100, the compressing pieces 10 causes a vascular network to collapse while holding the living body tissue by the arm parts 5a and 5b. Therefore, when the arm parts 5a and 5b hold the mucosal tissue of the tubular organ and excitation light is applied thereto, the fluorescence emitted by the compressing pieces 10 can be satisfactorily confirmed from the serosal side.
