The invention discloses a preparation method of anti-adhesion particles. The invention belongs to the technical field of biomedical materials. The raw materials used in the invention are all biocompatible materials, and inflammatory reaction and toxic residue are avoided through a natural cross-linking agent and non-toxic solvent system; through the synergistic effect and cross-linking treatment of the carboxymethyl cellulose, the chitosan and the polylactic acid, the particles can maintain the anti-adhesion effect for 7-14 days in vivo, and the key adhesion prevention period after soft tissue and urinary surgery is covered; the particles have flexibility, antibacterial property and urine corrosion resistance, can be used for preventing adhesion of soft tissue postoperative wounds, and can also be used for preventing adhesion of urinary surgical operation sites and modifying instrument surfaces; the low-temperature spray drying and gamma-ray sterilization process ensures the activity of the raw materials and the sterility of the product, the process parameters are easy to control, the method is suitable for industrial production, and the production cost is reduced compared with the existing like products.

This invention belongs to the field of medical image processing technology, specifically relating to a kidney segmentation method based on key point localization. The method includes the following steps: acquiring medical images of the kidney to be segmented and preprocessing the images; defining a set of anatomical key points specifically for kidney segmentation; predicting the position coordinates of each key point in the key point set using a model; constructing spatial topological relationships between key points based on the predicted key point coordinates and kidney anatomical zoning rules; and dividing the kidney parenchyma into regions according to the spatial topological relationships and kidney anatomical zoning rules, outputting the segmentation results for each kidney segment. This invention achieves efficient and accurate automatic kidney segmentation by precisely detecting anatomical key points and combining them with the anatomical rules of the Graves kidney segment model, outputting segmentation results with anatomical interpretability, and providing reliable technical support for preoperative planning of urological surgeries such as precise nephrectomy.

This invention belongs to the field of image processing technology, specifically relating to a method for enhancing the clarity of urological endoscopic video based on image enhancement, comprising the following steps: Step S110, acquiring the original endoscopic video stream, performing adaptive noise suppression and color correction preprocessing on each frame of the original RGB image in the video stream to generate a preprocessed image; Step S120, performing adaptive contrast enhancement and detail sharpening processing on the preprocessed image to generate an enhanced image; Step S130, inputting the enhanced image into a lightweight super-resolution reconstruction model for resolution enhancement processing to generate a high-resolution output image; Employing a lightweight super-resolution network model with reduced channel count and residual dense connections, supplemented by hardware acceleration and model quantization techniques, this method significantly reduces computational complexity and memory usage while ensuring image resolution enhancement, thus meeting the stringent real-time requirements of video processing in urological surgery.
