[0002] A surgical medical device sterilization device refers to a professional device used to kill various microorganisms on surgical medical devices, including bacteria, viruses, fungi, spores, etc., so as to make them reach a sterile state to prevent infections during surgical procedures. Such devices achieve sterilization through physical, chemical, or physical-chemical combined methods. According to different principles and application scopes, they can be divided into various types such as autoclaves, ethylene oxide sterilizers, hydrogen peroxide plasma sterilizers, dry heat sterilizers, etc. They are important devices for medical institutions' operating rooms, supply rooms, etc. to ensure the sterile quality of surgical instruments and ensure surgical safety; in existing rotary medical device sterilization devices, usually a sterile bag is used to isolate between the medical device and the device to prevent the medical device from colliding with the hard position of the device during rotation, resulting in damage to the instrument.

The connecting pipe 53 is evenly installed along the center of the filter chamber 52. Through the connection between the connecting pipe 53 and the tank body 201, the medicine is introduced into the filter chamber 52 from the bottom of the tank body 201 through the connecting pipe 53 after the sterilization treatment is completed. In the process of introducing the medicine into the filter chamber 52, the medicine first contacts the conical disk 54 under its own gravity and falls on the top of the conical disk 54. The top end of the connecting pipe 53 is fixedly connected to the bottom of the tank body 201, and the top end of the connecting pipe 53 passes through the tank body 201 and extends to the inside thereof.

Then, the sterilizing agent inside the agent box 3 is driven by the liquid pump 4 and introduced into the sterilization tank 2 along the pipeline. At the same time, the sterilization tank 2 drives the grid tube 8 and the wrapping bag 6 to rotate, so that the device can be evenly contacted with the agent during the rotation process to achieve sterilization. Then, the agent enters the drainage mechanism 5 under its own gravity, and the agent contacting the device is filtered by the drainage mechanism 5, and then the sterilizing agent is exported out of the equipment. Finally, the device inside the sterilization tank 2 is taken out to complete the sterilization process.

[0022] When installing the wrapping bag 6, firstly, the wrapping bag 6 is stuck into the interior of the grille tube 8 so that the connecting plate 13 is at the top of the conical tube 15. Then, the bag support ring 10 is placed into the interior of the wrapping bag 6 so that the outer side of the bag support ring 10 cooperates with the rubber ring 11. While the wrapping bag 6 is propped up, the contact pressure between the rubber ring 11 and the wrapping bag 6 causes the rubber ring 11 to deform and fully contact the wrapping bag 6, thereby increasing the friction between the rubber ring 11 and the wrapping bag 6.

[0023] In the sterilization tank 2, after the instruments to be sterilized are placed, the tank lid 202 is assembled with the tank body 201 and communicated with the liquid outlet of the liquid pump 4 through the connector 203. The medicament is driven by the liquid pump 4 and introduced into the tank body 201 through the pipeline from the connector 203, and falls from the central position at the top of the grille cylinder 8. At the same time, the motor 207 drives the grille cylinder 8 to rotate through the transmission shaft 211, driving the wrapping bag 6 and the internal instruments to rotate. During the rotation process, in cooperation with the falling of the sterilization medicament, after the sterilization medicament contacts the instruments, it moves around under the action of the rotational centrifugal force, fully contacting the instruments to achieve the sterilization treatment. At the same time, during the movement around, when the medicament contacts the inner wall of the tank body 201, the outer baffle 205 guides the medicament, making it re-introduced into the interior of the grille cylinder 8 along the outer baffle 205, so that all the medicaments are finally discharged from the bottom of the grille cylinder 8 and introduced into the liquid discharge mechanism 5 from the bottom of the tank body 201.

[0024] In the liquid discharge mechanism 5, through the connection with the tank body 201 by the connecting pipe 53, after the medicament completes the sterilization treatment, it is introduced into the filter chamber 52 from the bottom of the tank body 201 through the connecting pipe 53. During the introduction into the filter chamber 52, under the action of its own gravity, the medicament first contacts the conical surface disk 54 and falls on the top of the conical surface disk 54. Subsequently, it flows obliquely towards the central position along the conical surface at the top of the conical surface disk 54 under its own gravity. During the flowing process, the solids in the medicament are blocked by the annular groove at the top of the conical surface disk 54. Subsequently, the medicament falls through the arc through groove at the central position and enters the top of the filter disk 55. The filter disk 55 filters the medicament again, and the filtered medicament is discharged through the liquid guide pipe 51.
