Provided is an endoscopic treatment method for resecting a full thickness of a gastrointestinal wall under an endoscope, the method including: making a full circumferential incision in tissue around a target tissue up to a submucosal layer; fixing a traction device to a first location positioned further outside the target tissue; pulling the first location using the traction device so that a first region and a second region are folded and approach each other along a fold line that passes through the first location and divides the target tissue into the first region and the second region, to lift the full thickness of the gastrointestinal wall including the target tissue toward a gastrointestinal lumen side; suturing the submucosal layer exposed by full circumferential incision; and resecting the target tissue placed in the lumen side of the sutured area.

The invention discloses a submicron bone pathological sample three-dimensional reconstruction method based on integration of cutting, measurement and analysis, and the method comprises the following steps: step 1, carrying out an integral dyeing scheme on hard bone tissues which are not decalcified so as to realize uniform marking of cells and matrix components in a full thickness range of a sample; step 2, carrying out dehydration and resin embedding treatment on the bone tissue sample subjected to integral dyeing, so that the bone tissue sample becomes a firm block suitable for ultrathin cutting; 3, ultra-precise continuous cutting and in-situ imaging are carried out in a cutting-measuring-imaging integrated in-situ machining mode; 4, after the images of all slice layers are acquired, performing digital processing and three-dimensional reconstruction on a large amount of acquired two-dimensional image data; 5, after the high-resolution three-dimensional reconstruction model of the bone tissue is obtained, quantitative analysis and visual display are conducted on the high-resolution three-dimensional reconstruction model of the bone tissue. According to the method, the resolution and continuity of bone tissue pathological analysis are greatly improved, and the defects of traditional pathological two-dimensional diagnosis are effectively overcome.
