The invention discloses a nanometer microwave hemorrhoid postoperative nursing instrument. The nanometer microwave hemorrhoid postoperative nursing instrument mainly comprises a nursing module, a control module, a power module and a microwave generation module; according to the nursing module, a nanometer antibacterial layer which is obtained by mixing nanoscale silver powder and nanoscale alumina powder is adopted, and therefore, bacterial reproduction and viruses can be effectively suppressed, the peripheral region of an operative wound can be cleaned, and an effective antibacterial effect can be realized; according to the microwave generation module, under the heat effect of microwaves and fast conversion of the polarity of polar molecules, bacteria can be killed, and therefore, sterilization and disinfection can be realized, and the wound will not be infected; and microwave irradiation will cause biological effects, blood circulation can be increased, and therefore, adequate nutrients can be provided for the wound, and the healing of the wound can be accelerated. According to the nursing instrument of the invention, nanometer antibacterial effect, microwave therapy and muscle massage are effectively combined, and therefore, muscles at the wound of a hemorrhoid can be relaxed, and postoperative recovery can be accelerated.
