Description

Technical Field

[0001] The present invention relates to the field of surgical instrument disinfection, and in particular to an automated surgical instrument disinfection device. Background Art

[0002] Disinfection refers to a method that kills pathogenic microorganisms, but not necessarily bacterial spores. Chemical methods are usually used to achieve the effect of disinfection. Chemical drugs used for disinfection are called disinfectants. Sterilization refers to a method that kills all microorganisms on an object, including bacterial spores. Physical methods are usually used to achieve the purpose of sterilization. The disinfection effect varies for infectious diseases caused by different transmission mechanisms. Patent: CN215938391U discloses a renal surgical instrument disinfection device, including a disinfection box, the bottom surface of which is fixedly connected to two groups of support legs, the inner top wall of which is fixedly connected to fixed blocks arranged at equal distances, the bottom surface of each of the fixed blocks is commonly fixedly connected to a support plate, the bottom surface of the support plate is fixedly connected to ultraviolet sterilization lamps arranged at equal distances, and the inner wall of the disinfection box is provided with two slide grooves. The renal surgical instrument disinfection device, through the cooperation of the set slide groove, slide cylinder and slide column, fixes the slide cylinder and the connecting plate together. When the electric telescopic rod drives the connecting plate and the placement plate to move downward together, the slide cylinder will move up and down on the slide column, so that the placement plate can be more stable when it descends, which is beneficial to the disinfection of surgical instruments. The set spring can buffer the force of the slide cylinder when it descends, so that the placement plate can be more stable, which is convenient for the disinfection of surgical instruments. During the use of the device in the above technology, the placement plate is controlled to descend by an electric telescopic rod, so that the instrument is immersed in the medicine basin for immersion disinfection. The device cannot rinse the stains remaining on the surface of the instrument. Simple immersion cannot ensure that some difficult-to-clean stains are removed cleanly. In addition, when too many instruments are placed on the placement plate and stacked together, the contact surfaces between the instruments cannot be well contacted with the disinfectant, resulting in incomplete immersion disinfection. Improvement is needed. For this reason, we propose an automated disinfection device for surgical instruments. Summary of the invention
