The invention discloses an improved BM3D image denoising method based on multi-element fusion block similarity measurement. According to the method, wavelet decomposition is carried out on a noise image, a noise standard deviation is stably estimated on a highest-frequency sub-band, BM3D parameters are initialized, in a basic estimation stage, pixel intensity, local variance and gradient difference are fused to construct block similarity measurement, similar block matching grouping and three-dimensional block group construction are realized, and the method has the advantages of being high in robustness and high in robustness. And in a final estimation stage, a basic estimation image is obtained through three-dimensional collaborative hard threshold filtering and weighted aggregation, in the final estimation stage, secondary matching is guided by the basic estimation image, a three-dimensional block group is constructed again, a structure and texture adjustment factor is introduced to form an adaptive Wiener coefficient for Wiener collaborative filtering, and finally, a target de-noised image is output through weighted aggregation. In the whole process, the phenomena of mismatching and over-smoothing of a traditional BM3D algorithm under the condition of high noise can be reduced, the edge and texture detail keeping capability is enhanced, and the denoising quality of a noise image is improved.

The application relates to a tearable stripping sheath and a lithotripsy sheath kit for a percutaneous nephroscope, a cross section of a skin sheath tube is designed as a hollow ellipse, a short axis direction of an elliptical section is consistent with a partition plate, extrusion damage to kidney parenchyma during puncture expansion is reduced, and a long axis direction guarantees a larger operation space for the nephroscope and negative pressure suction; a chamber partition plate is arranged along the short axis direction of the skin sheath tube, and the skin sheath tube is divided into independent first and second chambers, and is connected with a lithotripsy mirror through hole and a negative pressure suction channel pipe respectively, the nephroscope and the negative pressure suction channel are completely isolated, interference between instrument operation and lithotripsy suction is avoided, nephroscope field of view definition and instrument steering flexibility are improved, the second chamber is specially used for negative pressure suction, and an independent chamber structure reduces the risk of channel blockage caused by blood clots or large-particle lithotripsy accumulation; detachable connection design of the partition plate and a sealing plug is convenient for selective use of chamber separation function or switching to a single chamber mode (such as expanding the operation space in special cases).
