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 ultrasonic knife comprises a sleeve, an amplitude-change pole, a blade, a water inlet and a water outlet, the sleeve is of a cylindrical shell-shaped structure with a notch in the side face, the amplitude-change pole, a water inlet pipe opening, a water outlet pipe opening and the blade are placed in the sleeve, the blade is connected with the amplitude-change pole, and the blade is provided with saw-toothed edges on one side or two sides. And the main body of the blade protrudes out of the side notch of the sleeve. The water outlet is used for spraying a solution to reduce the temperature of the cutter body, and the water inlet is used for generating suction negative pressure and discharging cut tissue fragments. The ultrasonic knife provided by the invention has the advantages that rapid, safe and thickness-controllable excision of thin-layer tissues is realized, and the effect of enucleating the tissues is realized; meanwhile, the device has the advantages of being good in hemostasis effect, small in heat damage, little in smoke and the like, and a new operation thought is provided for excision of hyperplasia tissues in cavities such as artery plaques, benign prostatic hyperplasia and esophageal leiomyoma. The problems that the size is too large, the thickness is uncontrollable and the efficiency is low when the thin-layer tissue in the cavity is cut are solved.

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.

A method for treating a patient's skin is provided. The method includes identifying at least one region of said patient's skin in need of treatment. The method includes forming at least one interference of at least one tissue portion in said region of skin, thereby generating at least one scar-like fibrous tissue in said region of said patient's skin. Rotational Fractional Resection (“RFR”) is a procedure which may be used to achieve focal aesthetic contouring by removing fractions of lax skin and excess fat tissue from a patient. Skin may be removed by the use of a rotating micro-coring punch, which is a hollow, sharpened tube which excises full thickness dermal resections. Such punch has been adapted to treat, among other conditions, scars, acne scars, lines, wrinkles, stretch marks, melasma, and to improve skin texture and tighten the skin.
