Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular to a surgical tool disinfection device. Background Art

[0002] In the medical device sector, cleaning and disinfection of general surgery instruments (such as scalpels, retractors, hemostats, and scissors) is crucial for ensuring patient safety and preventing nosocomial infections. Traditional surgical instrument disinfection methods primarily include immersion cleaning, manual scrubbing, and irradiation with fixed-position ultraviolet light.

[0003] However, these traditional methods have many shortcomings, such as: (1) Traditional immersion cleaning usually places surgical tools in a solution containing disinfectants. Although this method can play a certain role in cleaning surface contamination, it is difficult to completely remove stains on the inside and hidden parts of surgical tools with complex shapes or grooves and gaps. (2) In order to make up for the shortcomings of static immersion, many medical institutions also use manual scrubbing. However, this not only increases the workload of medical staff, but also due to the limitations of manual operation, it cannot guarantee that the same cleaning effect can be achieved every time, and it is easy to cause incomplete cleaning. Most existing technologies rely on only one or two disinfection methods (such as chemical disinfectants and ultraviolet rays). For complex solid contaminants, their cleaning effect is often not ideal, and it is difficult to ensure the cleaning effect of surgical tools.

[0004] After searching, the existing Chinese patent publication number: CN217772818U is a surgical scalpel disinfection device, including a disinfection box for disinfecting scalpels, a placement portion for placing the scalpel inside the disinfection box; the placement portion includes a mounting plate and a driving portion for changing the position of the mounting plate, the mounting plate is installed in the disinfection box through a buffer spring, the mounting plate is detachably provided with a placement box for placing the scalpel, a plurality of through holes are opened on the placement box, and a straight rack is provided at the bottom of the horizontal plate of the mounting plate; the driving portion includes a rotating shaft driven by an external driving device.

[0005] The patent documents cited above also have the same problem. Most existing technologies rely on only one or two disinfection methods (such as chemical disinfectants and ultraviolet rays). The cleaning effect is often not ideal for complex solid contaminants, making it difficult to ensure the cleaning effect of surgical tools. Summary of the Invention

[0008] Preferably, a drainage faucet is installed through the outer wall of one side of the disinfection cabinet base, and the bottom of the disinfection chamber is connected to the inner end of the drainage faucet through a pipe.

[0009] Preferably, one end of the sterilization rotating cage has an open opening for placing and taking out surgical tools, a detachable cage door is clamped on the open opening, and lock buckles are symmetrically provided on the outer wall of the frame of the sterilization rotating cage, and the lock buckles are locked on the detachable cage door.

[0010] Preferably, handles are symmetrically welded on both sides of the detachable cage door and on the outer wall of the frame of the sterilizing rotating cage, and a rotating shaft is fixed on the central axis of the sterilizing rotating cage.

[0011] Preferably, the polished rods at both ends of the rotating shaft are connected to the inner wall of the disinfection chamber through bearings, and one end of the rotating shaft is provided with a driving end portion, which is driven and connected to the rotating motor.

[0012] Preferably, the rotating shaft is located on the peripheral side of the sterilizing rotating cage and a fixed sleeve is provided. A plurality of cleaning brushes are provided in a circular array around the fixed sleeve, and each of the cleaning brushes abuts against the inner wall of the cleaning protection net.

[0013] Preferably, a plurality of connecting support plates are fixed in an annular array on the peripheral outer wall of the fixed sleeve, and each of the cleaning brushes is fixed on the free end of each connecting support plate.

[0014] Preferably, a plurality of pulling ropes are symmetrically fixedly connected to the peripheral outer wall of the fixed sleeve, and a striking body is fixed to one end of each pulling rope away from the fixed sleeve; The impact body is spherical and made of rubber. In the sterilizing rotating cage, the impact body impacts the inner wall of the sterilizing rotating cage and the cleaning protection net and the surgical tool with the rotating centrifugal force.

[0015] Preferably, the two disinfecting ultraviolet lamp tubes have a lampshade shell on the outside, and the two lampshade shells have fan-shaped irradiation ends on opposite sides, and the two fan-shaped irradiation ends are both facing the disinfection rotating cage. A support connecting plate is welded between the outer walls of the two lampshade shells, and two L-connecting seats are symmetrically welded on the top surface of the support connecting plate, and the L-connecting seats are fixedly connected to the flip cover by bolts.

[0016] This solution is preferred, and a drying hot air pipe is fixed on the inner wall of the supporting connecting plate and located between the two disinfecting ultraviolet lamp tubes, and a plurality of nozzles are equidistantly arranged on the side of the drying hot air pipe facing the disinfection rotating cage, and an air pump is installed on the outer wall of the flip cover, and the outer end of the air pump is connected to the external hot air blower through a pipe, and an air hole is opened on the top surface of the supporting connecting plate, and the inner end of the air pump passes through the air hole through a hose and penetrates into the drying hot air pipe.

[0017] Compared with the prior art, the technical effects and advantages of the present invention are: This surgical tool disinfection device installs a rotatable sterilization rotating cage in the disinfection chamber, allowing surgical tools to tumble continuously during the cleaning process. Compared to traditional static immersion cleaning, this dynamic cleaning method greatly increases the contact area between the surgical tool surface and the cleaning fluid, enhancing the cleaning effect.

[0018] The cleaning brush, fixed to the sterilization rotating cage, continuously rubs the surface of surgical tools as the rotating shaft rotates, effectively removing stubborn stains. Simultaneously, the impactor, under the action of centrifugal force, impacts the cleaning screen and surgical tools, further loosening and removing attached solid impurities, ensuring a more thorough cleaning.

[0019] A multi-layered disinfection system combines chemical disinfection (using disinfectant), physical cleaning (using brushes and impactors), and ultraviolet (UV) sterilization (using UV lamps). Each layer specifically addresses different types of contaminants, providing a more comprehensive and efficient disinfection system. The UV lamps are mounted on the inner wall of the flip cover, with fan-shaped irradiation tips focused on the sterilization rotating cage and the surgical tools within. This design ensures that the UV light reaches every corner, avoiding blind spots and enhancing the ultimate sterility level.

[0020] An air pump and external hot air blower are introduced to deliver uniform hot air to the surgical instruments within the sterilization rotating cage via hot air ducts and nozzles. This not only accelerates moisture evaporation and reduces drying time, but also avoids the risk of secondary contamination from natural drying. Maintaining the sterilization rotating cage's slow rotation during the drying process helps distribute the hot air more evenly to each surgical instrument and allows for full UV exposure, further ensuring effective drying and sterilization.

[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] This embodiment provides Figures 1 to 6 The surgical tool disinfection processing device shown includes a disinfection cabinet base 1. A disinfection box 2 is provided on the top of the disinfection cabinet base 1. The disinfection box 2 has a disinfection chamber 4 for cleaning and disinfecting surgical tools. A disinfection rotating cage 5 is rotatably installed in the disinfection chamber 4. The disinfection rotating cage 5 has a frame structure and is wrapped with a cleaning protective net 6 on the outside. The disinfection chamber 4 contains a cleaning disinfectant solution. The bottom of the disinfection rotating cage 5 is immersed in the cleaning disinfectant solution. The surgical tools are placed in the disinfection rotating cage 5 and immersed in the cleaning disinfectant solution. A rotating motor for driving the disinfection rotating cage 5 to rotate in the disinfection chamber 4 is provided outside the disinfection chamber 4 and inside the disinfection box 2. The inner wall of the flip cover 3 has a disinfection ultraviolet lamp 20 for disinfecting surgical tools. Support legs 8 are fixed to the four corners of the bottom surface of the disinfection cabinet base 1.

[0027] In this embodiment, a drain faucet 7 is installed through the outer wall of one side of the disinfection cabinet base 1, and the bottom of the disinfection chamber 4 is connected to the inner end of the drain faucet 7 through a pipe fitting.

[0028] In this embodiment, one end of the sterilization rotating cage 5 has an open opening for placing and removing surgical tools, and a detachable cage door 10 is clamped on the open opening. The outer wall of the frame of the sterilization rotating cage 5 is symmetrically provided with locks 11, which are locked on the detachable cage door 10.

[0029] In this embodiment, handles 12 are symmetrically welded on both sides of the detachable cage door 10 and on the outer wall of the frame of the disinfection rotating cage 5 , and a rotating shaft 13 is fixed on the central axis of the disinfection rotating cage 5 .

[0030] In this embodiment, the polished rods at both ends of the rotating shaft 13 are connected to the inner wall of the disinfection chamber 4 through bearings. One end of the rotating shaft 13 is provided with a driving end 15, which is driven by a rotating motor.

[0031] In this embodiment, the rotating shaft 13 is located on the circumferential side of the sterilizing rotating cage 5 and is fixed with a fixed shaft sleeve 14. A plurality of cleaning brushes 17 are arranged in an annular array around the circumferential side of the fixed shaft sleeve 14. Each cleaning brush 17 abuts against the inner wall of the cleaning protection net 6. When the sterilizing rotating cage 5 rotates, it will inevitably drive the surgical tool to flip in the sterilizing rotating cage 5. The arrangement and length of the cleaning brush 17 abut against the inner wall of the cleaning protection net 6 enable the surgical tool to roll in the cleaning brush 17, thereby increasing the contact cleaning area of the cleaning brush 17. At the same time, the sharp end of the cleaning brush 17 can generate friction with the surface of the surgical tool, thereby further cleaning out fixed impurities. At the same time, the abutment of the cleaning brush 17 against the inner wall of the cleaning protection net 6 can remove blocked solid impurities.

[0032] In this embodiment, a plurality of connecting support plates 16 are fixed in an annular array on the peripheral outer wall of the fixed sleeve 14 , and each cleaning brush 17 is fixed on the free end of each connecting support plate 16 .

[0033] In this embodiment, a plurality of pulling ropes 19 are symmetrically fixedly connected to the outer wall of the circumference of the fixed sleeve 14, and an impact body 18 is fixed to the end of each pulling rope 19 away from the fixed sleeve 14. The impact body 18 is spherical and made of rubber. The impact body 18 impacts the inner wall of the disinfection rotating cage 5 and the cleaning protection net 6 and the surgical tool with the rotating centrifugal force in the disinfection rotating cage 5. When the impact body 18 impacts the cleaning protection net 6, it will not only not damage the cleaning protection net 6 due to the rubber material, but also can impact the cleaning protection net 6 to knock off the accumulated fixed impurities and prevent the cleaning protection net 6 from being blocked. In addition, when the impact body 18 impacts the surgical tool, it can not only knock and vibrate the fixed impurities attached to the surgical tool, but also adjust the position and direction of the surgical tool under the action of the impact force and flip the surgical tool to the other side, thereby further improving the scope of cleaning and disinfection and reducing the blind spots of cleaning and disinfection. When the impact body 18 impacts the inner wall of the sterilization rotating cage 5, the sterilization rotating cage 5 is caused to vibrate. This vibration can be transmitted to the surgical tool, thereby causing the surgical tool to vibrate and shake off solid impurities.

[0034] In this embodiment, the two disinfecting ultraviolet lamp tubes 20 are each provided with a lampshade shell 22 on the outside. The two lampshade shells 22 have fan-shaped irradiation ends 27 on opposite sides. The two fan-shaped irradiation ends 27 are both facing the disinfection rotating cage 5. A support connecting plate 23 is welded between the outer walls of the two lampshade shells 22. Two L-shaped connecting seats 26 are symmetrically welded on the top surface of the support connecting plate 23. The L-shaped connecting seats 26 are fixedly connected to the flip cover 3 by bolts. The fan-shaped irradiation end 27 is located on one side of the lampshade shell 22, which expands the irradiation area of the disinfecting ultraviolet lamp tube 20 and ensures that there are no blind spots during disinfection.

[0035] In this embodiment, a drying hot air pipe 21 is fixed to the inner wall of the supporting connecting plate 23 and is located between the two disinfecting ultraviolet lamps 20. A plurality of nozzles 25 are equidistantly arranged on the side of the drying hot air pipe 21 facing the disinfection rotating cage 5. The nozzles 25 are distributed on the drying hot air pipe 21 to evenly disperse the hot air into the disinfection rotating cage 5 to ensure that the surgical tools are fully dried. An air pump 9 is installed on the outer wall of the flip cover 3. The outer end of the air pump 9 is connected to an external hot air blower through a pipe. An air hole 24 is opened on the top surface of the supporting connecting plate 23. The inner end of the air pump 9 passes through the air hole 24 through a hose and penetrates the drying hot air pipe 21. The hot air from the hot air blower is transported to the drying hot air pipe 21 through the air pump 9 and blown to the surgical tools in the disinfection rotating cage 5 through the nozzles 25. First, it is necessary to clean the rotating sterilization rotating cage 5 with a cleaning disinfectant to clean the surgical tools in the sterilization rotating cage 5. During the cleaning process, the cleaning brush 17 and the impact body 18 are cleaned for a long time. After cleaning, the cleaning disinfectant in the sterilization box 2 is discharged through the drain faucet 7. At this time, hot air blowing and sterilization by the sterilizing ultraviolet lamp 20 are carried out simultaneously to improve the disinfection efficiency.

[0036] Working principle: In this surgical tool disinfection device, the operator opens the flip cover 3 and places the surgical tools to be sterilized into the sterilization rotating cage 5 through the removable cage door 10. A lock 11 ensures that the removable cage door 10 remains closed during the disinfection process, preventing the surgical tools from accidentally falling. The required cleaning and disinfecting solution is added to the disinfection chamber 4 to ensure that the bottom of the sterilization rotating cage 5 is fully covered with the liquid.

[0037] The rotating motor located outside the disinfection cabinet base 1 is started, and the disinfection rotating cage 5 is driven to start rotating through the driving end 15 and the rotating shaft 13. The rotation process causes the surgical tools to roll inside the disinfection rotating cage 5, increasing their contact area with the cleaning protection net 6 and the cleaning brush 17. As the disinfection rotating cage 5 rotates, the cleaning brush 17 fixed to the fixed shaft sleeve 14 continuously rubs the surface of the surgical tools, helping to remove stubborn stains. At the same time, the impact body 18 connected to the pulling rope 19 collides back and forth between the inner wall of the disinfection rotating cage 5, the cleaning protection net 6 and the surgical tools due to the action of centrifugal force, further loosening and removing attached solid impurities. The surgical tools immersed in the cleaning and disinfecting solution are subjected to the action of chemical agents and undergo preliminary disinfection. The cleaning and disinfecting solution usually contains active ingredients that can kill bacteria, viruses and other pathogens.

[0038] When the cleaning and disinfection cycle is finished, the motor is stopped and the drain tap 7 is opened. The cleaning and disinfection liquid is discharged from the bottom of the disinfection chamber 4 through the pipe fitting to ensure that all used liquids are completely removed to avoid cross contamination.

[0039] Start the air pump 9 and introduce hot air into the drying hot air pipe 21 through an externally connected hot air blower. The hot air is evenly blown onto the surgical tools in the sterilization rotating cage 5 through the air nozzle 25, accelerating the evaporation of moisture on their surface and achieving rapid drying. At the same time, turn on the sterilization ultraviolet lamp 20 installed on the inner wall of the flip cover 3. The ultraviolet light emitted by the lamp is concentratedly irradiated onto the sterilization rotating cage 5 and the surgical tools inside it through the fan-shaped irradiation end 27 to perform deep sterilization. Ultraviolet rays have a strong bactericidal ability and can effectively kill residual microorganisms, ensuring that the surgical tools reach a sterile state. During the drying and ultraviolet disinfection period, continue to run the rotary motor to keep the sterilization rotating cage 5 rotating slowly. This not only helps to evenly distribute the hot air, but also allows the ultraviolet light to irradiate each surgical tool in all directions, improving the disinfection effect.

[0040] After drying and disinfection, all equipment is turned off and a period of time is allowed to pass to ensure that the surgical tools are completely cooled. Finally, the operator opens the flap 3 and the removable cage door 10 again and carefully removes the surgical tools that have been cleaned and disinfected, ready for the next medical procedure.
