The invention belongs to the technical field of a surgery part infection risk predicating scoring and a system based on independent danger factors. Particularly the invention relates to a risk predicting evaluation scoring method for neck anastomosis esophagus cancer resection surgery part infection and a system thereof. According to the independent danger factors which are firstly screened, an infection predicting model is established. According to an assignment score which is generated by a formula, the influence of the danger factors to a final result-surgery part infection can be more visually presented, thereby facilitating clinical early prediction and evaluation to possibility of surgery part infection after the surgery. Individualized infection risk evaluation supplies a basis forkey disposition of an infection preventing measure. The content of the invention is not reported in China and other countries. Through data statistics analysis, the independent predicting factors forneck anastomosis esophagus cancer resection surgery part infection are screened. A mathematical model is used for establishing the predicting scoring system for the surgery infection risks, thereby laying a certain basis for individually predicting the surgery part infection, and supplying guidance for clinical early intervention measure application.

The invention relates to a surgical suture with antibacterial and shape memory functions and a preparation method thereof. The structure of the shape memory polyurethane is shown as a formula I in thespecification. The invention also provides a shape memory surgical suture with antibacterial property, which is prepared from the shape memory polyurethane and an antibacterial drug as raw materialsthrough a spinning process. The surgical suture line is good in biocompatibility, has an excellent shape memory function, can effectively avoid mechanical traction necrosis of a wound in the process of folding the surgical suture line after an operation (especially an operation of deep organs and a narrow operation visual field) is completed, and reduces the wound infection risk; meanwhile, the operation difficulty can be reduced, and the operation time is shortened. Besides, the surgical suture provided by the invention has an obvious inhibition effect on gram-negative bacteria and gram-positive bacteria, can significantly reduce the infection risk of a surgical site and significantly improve the healing ability of a wound after suture, and has a wide application prospect.
