The invention relates to a medical multifunctional sterilization and disinfection instrument. The instrument comprises an upper main shaft, a lower main shaft, an upper disc frame, a lower disc frame,an upper cover bin, a middle bin, a lower cover bin and a temperature measuring sensor, wherein the upper main shaft and the lower main shaft are used for driving the upper disc frame and the lower disc frame connected to the upper main shaft and the lower main shaft to move up and down, fixed hooks arranged on the upper disc frame and the lower disc frame can relatively rotate along a groove cavity of a groove in a semisphere, two ends of the middle bin can rotatably move relative to the upper cover bin and the lower cover bin, a plurality of penetrated air inlets are formed in the bin wallsof the upper cover bin and the lower cover bin, and the outer wall of the middle bin is connected with the temperature measuring sensor; and the temperature measuring sensor is located in the same circuit loop with a signal emitter and a power supply and comprises a metal shell, an input power supply wire, an output power supply wire, an insulating column, a temperature sensing piece and a temperature inlet. The design of the instrument has relatively good disinfection effects and relatively high disinfection efficiency.
