The invention discloses a construction method, system, equipment, product and medium for an ablation protection area, and the method comprises the steps: obtaining a cross-sectional image set of a prostate target area, the cross-sectional image set comprising a first cross-sectional image comprising a bladder neck and at least one second cross-sectional image comprising verumontanum; according to the first cross section image, a first boundary contour corresponding to the bladder neck is determined, and the first boundary contour covers the sphincter in the urethra; according to the second cross section image, a second boundary contour corresponding to the verumontana is determined, and the second boundary contour covers the verumontana; according to the first boundary contour and the at least one second boundary contour, the ablation protection area in the prostate target area is determined, the problem that definition of a functional structure depends on subjective judgment of clinical experience is solved, the quantitative protection standard of the functional anatomical axis from the bladder neck to the prostatic urethra to the verumontana is achieved, and the protection effect is improved. The risk of urination function impairment and sexual function impairment induced by transurethral ablation operation is effectively controlled.

The invention discloses an ion-immune-electric coupling 3D bionic conductive catheter and a preparation method and application thereof, and belongs to the technical field of biomedical materials. According to the catheter, a gelatin / poly-L-lactic acid / polypyrrole nanofiber scaffold serves as a substrate, tannic acid and magnesium ions are loaded in sequence, and a three-dimensional bionic structure with electrical conductivity, ion slow release and immunoregulation functions is formed. The conductivity of the catheter is matched with that of the natural spinal cord, Mg can be continuously released to reduce excitatory toxicity of neurons, and macrophages are synergistically regulated and controlled to be polarized to M2 phenotype through tannic acid, so that oxidative stress and inflammation are relieved. In-vitro experiments show that the catheter can promote neural stem cells to differentiate into neurons and inhibit activation of astrocytes. In a rat full-cross-section spinal cord injury model, when the catheter is implanted, axon regeneration, myelin sheath formation and synaptic occurrence can be remarkably promoted, movement and urinary function recovery are effectively improved, and an innovative treatment strategy is provided for spinal cord injury repair.

This invention relates to the field of postoperative functional recovery prediction technology, specifically a method for predicting the recovery of voiding function after orthotopic neobladder surgery based on multimodal data. The method includes the following steps: acquiring volume, urine flow rate, and urethral pressure data and synchronizing them in time; organizing data according to the voiding cycle in conjunction with imaging information; dividing the voiding cycle into stages and assessing the recovery progress; and determining whether the recovery trend has deviated. In this invention, by synchronizing and integrating volume, urine flow rate, and urethral pressure data in time and organizing them uniformly with the imaging sequence according to the voiding cycle, multi-source information is continuously correlated within the same time axis. Based on the ratio of volume to flow rate and pressure abnormality markers, the dynamic changes in the voiding process are characterized. The recovery progress is assessed by combining stage division and trend fitting, and the stability and deviation of the continuous cycle trend are identified. This transforms the judgment of voiding function recovery from a static conclusion to a dynamic prediction with sustainable tracking, improving individual adaptability and clinical early warning value.
