The invention discloses a surgical incision healing state image intelligent evaluation method and system, and belongs to the technical field of image analysis and medical diagnosis assistion.The method comprises the steps that a preprocessed incision image is generated through dual-path self-adaptive image enhancement processing, and an incision area is extracted through a semantic segmentation network fused by a multi-scale feature pyramid; a comprehensive healing score is generated based on an adaptive feature weighted fusion strategy, healing trend prediction is constructed through a time sequence tracking module, an abnormal deterioration risk is identified, and an incision state is classified into one of normal healing, delayed healing, incision infection and incision cracking by adopting a multi-classification decision network. According to the method, the technical problems of insufficient image preprocessing capability, low incision segmentation precision, incomplete feature extraction, lack of time sequence tracking capability, single classification decision and the like in the prior art are solved, accurate, comprehensive and dynamic evaluation of the healing state of the surgical incision is realized, and reliable decision support is provided for clinic.

The application relates to the hedge pruning technical field, in particular to a garden greening hedge pruning device which comprises an adjusting arm, the end of the adjusting arm is rotationally connected with a mounting box, further comprises: clamping boxes, the clamping boxes are two, a pulling assembly is arranged between the clamping boxes and the mounting box, the pulling assembly is used for pulling the two clamping boxes to be close to each other to clamp the top-bud branches; a first flexible block is fixed on the outer wall of the clamping box; the top-bud branches are pruned in a sliding cutting mode, the extrusion damage to the top-bud branches in the pruning process is reduced, the branches are straightened through the first flexible block and a second flexible block, the knife edge is perpendicular to the branches during pruning, the flatness of the top-bud branch incision is ensured and the incision is in a minimum incision state, and the incision infection risk is reduced.

The invention provides an antibacterial hydrogel adhesive as well as a preparation method and application thereof, and belongs to the technical field of composite material preparation. The antibacterial hydrogel adhesive is prepared from silk fibroin, epigallocatechin gallate and gallic acid according to the mass ratio of (2 to 24) to (4 to 24) to 1. Phenolic hydroxyl groups in polyphenol molecules and polar groups of silk fibroin remarkably enhance the intermolecular binding force through the synergistic effect of hydrogen bond-hydrophobic interaction, and the multifunctional silk fibroin polyphenol hydrogel with excellent biocompatibility, high adhesion performance and broad-spectrum antibacterial property is successfully prepared. The antibacterial hydrogel adhesive disclosed by the invention can be firmly adhered to a cesarean delivery wet environment incision, effectively kills group B streptococcus, and prevents formation of uterine diverticulosis due to poor healing caused by incision infection.

The utility model relates to an incision infection resistant drainage bag which comprises a drainage bag body, the drainage bag body comprises a first sheet body and a second sheet body, the periphery of the first sheet body and the periphery of the second sheet body are closed to form the drainage bag, a liquid outlet pipe is arranged at an outlet of the drainage bag, and an anti-reflux sheet body is arranged between the first sheet body and the second sheet body. The anti-reflux sheet body and the first sheet body are connected to form an anti-reflux bag, and the anti-reflux bag is provided with an anti-reflux port; a bottom plate is arranged on the back face of the second sheet body, a drainage tube inserting opening is formed in the center of the bottom plate, and the bottom plate is provided with a plurality of marking leads which form concentric circles with the drainage tube inserting opening as the circle center. Compared with common gauze, the anti-bacterial base plate reduces infection opportunities. And seepage directly flows into the anti-reflux bag through the anti-reflux opening, so that the comfort is improved, secondary sewing is avoided, meanwhile, the anxiety of a patient is reduced, the skin of an incision of the patient is kept clean, dressing change is avoided, and the workload of medical workers is greatly reduced.

The utility model provides a novel integrative drainage tube structure of flushable, relate to medical instrument technical field, including flush drainage tube (1), one end of flush drainage tube (1) is equipped with negative pressure interface (2), the other end of flush drainage tube (1) is equipped with pipe body opening (5), the inside of flush drainage tube (1) is provided with inlet pipe (3), one end of inlet pipe (3) is equipped with water outlet (6) near pipe body opening (5), the other end of inlet pipe (3) is formed inlet (4) through the lateral wall of flush drainage tube (1), the negative pressure interface of this device is connected wall negative pressure or negative pressure drainage ware, and the negative pressure is bigger, and the effect of removing effusion is good, increases flush function simultaneously, reduces the obstruction of lumen, improves the effect of negative pressure, effectively prevents and reduces the incision infection after operation.
