Abstract: A tissue traction device includes a first needle connected to a distal end of a first thread; a second needle connected to a distal end of a second thread; an elongated main body connected to the first thread and extending between the first thread and the second thread, the main body being elastically deformable; a tube disposed at a proximal end of the main body; and a traction member having a distal end connected to a distal end portion of the main body, the traction member extending from the distal end portion of the main body toward a distal end of the tube.

Abstract: A tissue traction device includes a first needle connected to a distal end of a first thread; a second needle connected to a distal end of a second thread; an elongated main body connected to the first thread and extending between the first thread and the second thread, the main body including a first hole; and a tube disposed at a proximal end of the main body, wherein the second thread is inserted through the first hole to be advanceable and retractable at a position between the second needle and a distal end of the tube, and the tube and the second thread are configured to be relatively movable in a longitudinal direction of the tube.

Abstract: A medical system can include a light source configured to generate excitation light; and a processor including a memory, the processor: controlling energy supplied to an energy device, the light source generating the excitation light to generate fluorescence from the living body tissue heat treated by the energy device; generating a fluorescence image based on an image pickup signal obtained by imaging the living body tissue; and generating a control signal that restricts energy supply to the energy device and output the control signal to the energy control apparatus when a pixel value of at least one pixel in the fluorescence image exceeds a first threshold value.
