1. A soft endoscopy device, comprising an endoscope body structure, a camera assembly and an instrument adapter structure, wherein the endoscope body structure comprises a bendable flexible inserting portion and a handle portion connected to one end of the flexible inserting portion, the handle portion being provided with a first access port, and the flexible inserting portion being internally provided with a first passage; the first access port being directly or indirectly connected with the first passage;
the first access port being matched with the camera assembly, and when the camera assembly accesses the first access port, at least part of the camera assembly extending into the first passage;
the first access port being further matched with the instrument adapter structure, and when the instrument adapter structure accesses the first access port and the instrument adapter structure is equipped with a first instrument, the first instrument extending into the first passage;
the handle portion is further provided with a second access port for accessing a second instrument, a second passage for the second instrument to extend into penetrating through the flexible inserting portion, and the second access port being directly or indirectly connected with the second passage;
the flexible inserting portion comprises a bending rod, a head module and an optical indication module extending to the head module, one end of the bending rod being connected with the handle portion, and the other end of the bending rod being connected with the head module; both the first passage and the second passage for the second instrument to penetrate through penetrating through the bending rod, and both the first passage and the second passage extending into the head module; and the optical indication module being used to externally indicate a position of the instrument extending into the passage;
the head module is internally provided with a first head passage, a second head passage, a lighting component and at least one head optical fiber passage, the optical indication module comprising an illumination optical fiber, and the handle portion being provided with an observation window;
the first passage being docked with an inlet of the first head passage, the second passage being docked with an inlet of the second head passage, an optical import end of the head optical fiber passage extending to the first channel of the first head passage or the second head passage, and an instrument accessing the first head passage or the second head passage being capable of shielding the optical import end of the corresponding head optical fiber passage; and
the illumination optical fiber penetrating through the head optical fiber passage; when the optical import end is not shielded, a first end of the illumination optical fiber being capable of collecting an optical signal directly or indirectly transmitted by the lighting component; the illumination optical fiber further being capable of conducting the optical signal to a second end of the illumination optical fiber, and the second end of the illumination optical fiber extending into the handle portion and located at an inner side of the observation window.
