[0017] The principle and beneficial effects of the technical solution are:
[0018] 1. A surgical tool disinfection device for general surgery provided by the present invention. The top of the cylinder body is detachably connected with a cover body through threads or a flange plate to ensure that the inside of the cylinder body is in a sealed state to enhance the disinfection effect. An air outlet is provided on the side wall of the cylinder body. A filter layer is provided at the air outlet, and a sealing member is detachably connected to the air outlet. After disinfection, the gas flows out from the air outlet. The filter layer is provided with a catalyst that can decompose harmful gases such as ozone generated by ionization to avoid environmental pollution. A placement component is arranged inside the cylinder body. The placement component includes a sun gear and several planet gears. Each planet gear is provided with a bearing component, and the bearing component is used to place medical devices of different types of materials. For example, one is for placing metal types, one is for placing plastic types, one is for placing glass types, one is for placing fabric types, and so on. In this way, medical devices of different materials can be separated to avoid cross-infection caused by different types of medical devices being stacked together, realizing classified disinfection and improving the disinfection effect. And the cover body is connected with a plasma generating device through a telescopic rod. The jet port of the plasma generating device faces the bearing component. The plasma generating device is used to generate plasma, and the plasma is ejected from the jet port to disinfect the medical devices on the bearing component. In addition, an internal gear ring is provided on the inner wall of the cylinder body. The sun gear meshes with the planet gears respectively, and the planet gears all mesh with the internal gear ring. The cylinder body is rotatably connected with a planet carrier, and the planet gears are respectively rotatably connected with the planet carrier. The motor drives the sun gear to rotate. Under the action of the sun gear and the internal gear ring, while the planet gears and the planet carrier rotate circumferentially around the sun gear, they also rotate around their own axes. On the one hand, the rotation of the medical device enables each part of it to have a more sufficient opportunity to be exposed in the plasma field, which can increase the contact area between the medical device and the plasma, avoid the occurrence of disinfection dead corners, and allow the plasma to evenly cover its surface, thereby improving the uniformity of the overall disinfection effect. On the other hand, the rotating medical device can collide with the plasma, enhancing the interaction between the plasma and the surface of the device, that is, the rotation makes the surface of the medical device continuously make dynamic contact with the plasma, which helps the active particles in the plasma to more fully react chemically with the microorganisms, pollutants, etc. on the surface of the device. At the same time, the mechanical force generated by the rotation can also promote the flushing effect of the plasma on the surface of the device to a certain extent, accelerating the removal of pollutants and the inactivation of microorganisms, thereby improving the disinfection efficiency.
[0019] 2. A disinfection device for surgical tools in general surgery provided by the present invention. A sun gear is coaxially connected with a sleeve. A plurality of flow guiding plates are evenly spaced and connected to the side wall of the sleeve. The plate surface of the flow guiding plate is inclined with respect to the axial plane of the sleeve. The flow guiding plate rotates with the rotation of the sun gear, and can guide the plasma near the sun gear to the medical devices on the bearing assembly, avoiding the accumulation of plasma in the middle, and improving the disinfection efficiency and the utilization rate of plasma. In addition, the inclination direction of the flow guiding plate is the same as the rotation direction of the sun gear, that is, the included angle between the tangent at the connection of the sleeve and the flow guiding plate and the plane of the flow guiding plate is an acute angle. The rotation directions of the sun gear and the planetary gear are opposite. Therefore, the plasma guided by the flow guiding plate can collide with the medical devices, further promoting the flushing effect of the plasma on the surface of the devices and improving the disinfection efficiency. Moreover, the flow guiding plate and the medical devices can also drive the plasma to generate forced convection, making the plasma more evenly distributed in the chamber and increasing the contact area with the medical devices.

[0021] Specifically, the first fixing component is a number of elastic clips, which are used to fix metal medical devices such as scalpels, forceps, and surgical clamps. During use, the middle part is clamped by the elastic clips to fully expose the operating parts such as the end parts in the plasma, thereby enhancing the disinfection effect; the second fixing component is used to fix medical devices such as medical record folders and catheters. During use, the end part or the middle part is fixed by the elastic clips; the third fixing component is a number of arc-shaped fixing clamps. One end of the fixing clamp is rotatably connected to an arc-shaped movable clamp, and the other end of the fixing clamp is detachably connected to the movable clamp, which is used to fix medical devices such as glass bottles. During use, it is placed horizontally, and the glass bottle is fixed by the fixing clamp and the movable clamp, so that the plasma can fully contact the outer wall and the inner wall of the glass bottle, enhancing the disinfection effect. Moreover, under the conditions of self-rotation and revolution, the air flow can continuously enter and exit the glass bottle, enhancing the disinfection effect; in addition, springs are connected to the inner sides of the fixing clamp and the movable clamp, and the free ends of the springs are connected to arc-shaped support members, which can increase the clamping force and are applicable to glass bottles of different diameters; the fourth fixing component is a number of groups of oppositely arranged support rods, and a rope is connected between the two support rods, which is used to fix medical devices such as sphygmomanometer cuffs. During use, it is spread and hung on one or more ropes, and then clamped by clips, so that each part of the cuff is fully exposed in the plasma; therefore, the setting of the fixing component can not only fix the medical device, but also ensure that the medical device is fully exposed in the plasma, enhancing the disinfection effect.

The plasma generating device includes a support base, a power supply, and a plurality of jet components.

The telescopic rod includes an internally threaded tube, a first externally threaded rod, and a second externally threaded rod. By rotating the internally threaded tube, the vertical distance between the jet port and the medical device can be adjusted, which is convenient to operate; the vertical distance between the jet port and the disinfection device is 1 cm - 3 cm, and the disinfection time is 60 min - 120 min, which can ensure a good sterilization effect. Some studies have shown that the killing effect of plasma on microorganisms on the contaminated carrier from strong to weak is Escherichia coli, Staphylococcus aureus, Candida albicans, and Bacillus subtilis var. niger spores. When the distance between the jet port and the instrument is 1 cm, the disinfection time of Bacillus subtilis var. niger spores is 10 min.

The support base 29 is provided with a power supply 35. The bottom of the support base 29 is provided with a plurality of jet orifices 30. A plurality of jet components are arranged in the support base 29. The jet orifices 30 correspond to the jet components one by one.

Moreover, the vertical distance between the jet orifice 30 and the disinfection instrument is 1 cm - 3 cm. The disinfection time is 60 min - 120 min.
[0038] The specific implementation process is as follows:
[0039] When using this disinfection device, first place the medical devices after cleaning and drying on different carrier trays 15 according to their materials. Place metal medical devices such as scalpels, forceps, and surgical clamps on the first fixing component and clamp them with elastic clip pieces 17. Place plastic medical devices such as medical record folders and catheters on the second fixing component and clamp them with elastic clip pieces 17. Place glass medical devices such as glass bottles on the third fixing component and clamp them with fixed clamping parts 18, movable clamping parts 19, springs 21, and arc-shaped support parts 22. Place cloth medical devices such as sphygmomanometer cuffs on the fourth fixing component, spread them flat on the rope 24, and clamp them with clips. Adjust the telescopic component 16 to make the heights of the devices on each fixing component close. Rotate the internally threaded tube 27 to adjust the height of the plasma generation device so that the distance between it and the medical device is 1 - 3 cm. Seal the cover body 2 to the cylinder body 1. Start the motor 7. The motor 7 drives the sun gear 10 to rotate. The sun gear 10 and the internal gear ring 11 drive the four planetary gears 14 to rotate around their own axes and revolve around the sun gear 10. The deflector 13 rotates with the sun gear 10 and guides the plasma to the surfaces of the surrounding medical devices. After disinfection, open the sealing member 5. Through natural diffusion or by using an air pump, make the internal gas flow out from the air outlet 3. After decomposing harmful gases such as ozone through the filter layer 4, open the cover body 2 for sufficient ventilation.
[0040] Among them, the four carrier components are used to place medical devices of different materials, which can separate medical devices of different materials, avoid cross-infection caused by different types of medical devices being stacked together, achieve classified disinfection, and improve the disinfection effect. The plasma generation device is used to generate plasma, and the plasma shoots out from the jet port 30 to disinfect the medical devices on the carrier components. In addition, when the motor 7 drives the sun gear 10 to rotate, under the action of the sun gear 10 and the internal gear ring 11, while the planetary gear 14 and the planet carrier 9 rotate circumferentially around the sun gear 10, they also rotate around their own axes. On the one hand, the rotation of the medical device can make each part of it have a more sufficient opportunity to be exposed in the plasma field, increase the contact area between the medical device and the plasma, avoid the occurrence of disinfection dead spots, and allow the plasma to evenly cover its surface, thus improving the uniformity of the overall disinfection effect. On the other hand, the rotating medical device can collide with the plasma, enhancing the interaction between the plasma and the surface of the device, that is, the rotation makes the surface of the medical device constantly have dynamic contact with the plasma, which helps the active particles in the plasma to more fully react with the microorganisms, pollutants, etc. on the surface of the device. At the same time, the mechanical force generated by the rotation can also promote the flushing effect of the plasma on the surface of the device to a certain extent, accelerating the removal of pollutants and the inactivation of microorganisms, thereby improving the disinfection efficiency.
[0041] The deflector 13 rotates as the sun gear 10 rotates, and can direct the plasma near the sun gear 10 to the medical devices on the bearing assembly, avoiding the accumulation of plasma in the middle, and improving the disinfection efficiency and the utilization rate of plasma. In addition, the inclination direction of the deflector 13 is the same as the rotation direction of the sun gear 10, and the rotation directions of the sun gear 10 and the planetary gear 14 are opposite. Therefore, the plasma deflected by the deflector 13 can collide with the medical devices, further promoting the scouring effect of the plasma on the surface of the devices and improving the disinfection efficiency. Moreover, the deflector 13 and the medical devices can also drive the plasma to generate forced convection, making the plasma more evenly distributed in the chamber and increasing the contact area with the medical devices.
[0042] The first fixing component is a number of elastic clips 17, which are used to fix metal medical devices such as scalpels, forceps, and surgical clamps. The second fixing component is used to fix medical devices such as medical record folders and catheters. The third fixing component is used to fix medical devices such as glass bottles. The fourth fixing component is used to fix medical devices such as sphygmomanometer cuffs. While fixing the medical devices, it can also ensure that the medical devices are fully exposed to the plasma, increasing the disinfection effect. In addition, springs 21 are connected to the inner sides of the fixed clamping piece 18 and the movable clamping piece 19, and arc-shaped support pieces 22 are connected to the free ends of the springs 21, which can increase the clamping force and can be applicable to glass bottles with different diameters.
[0043] The plasma generating device includes a support base 29, a power supply 35, and a number of jet components. The compressed air pump 34 sends the compressed gas into the quartz glass tube 32 from the high-voltage electrode 31 end, and forms a plasma jet beam after passing through the ground electrode 33, and shoots the jet beam at each medical device. The jet components are evenly spaced along the circumference of the support base 29. The generated plasma jet is stable and uniform, which can ensure the disinfection effect on surgical tools. By rotating the inner threaded tube 27, the vertical distance between the jet orifice 30 and the medical device can be adjusted, and the operation is convenient. The vertical distance between the jet orifice 30 and the disinfected device is 1 cm - 3 cm, and the disinfection time is 60 min - 120 min, which can ensure a good sterilization effect. Research shows that the killing effect of plasma on microorganisms on the contaminated carrier from strong to weak is Escherichia coli, Staphylococcus aureus, Candida albicans, and Bacillus subtilis var. niger spores. When the distance between the jet orifice 30 and the device is 1 cm, the disinfection time of Bacillus subtilis var. niger spores is 10 min, and when the distance remains unchanged, the disinfection and sterilization effect increases with the prolongation of time.
[0044] On the inner wall of the cylinder body 1, there are several hemispherical protrusions 25. When the plasma passes through these protrusions 25, multiple scattering and collisions will occur, so that the medical device has more contact opportunities, further enhancing the disinfection effect; the carrier plate 15 and the planetary gear 14 are connected by a telescopic assembly 16, which can adjust the height of each carrier plate 15 as needed, making the distance between each medical device and the jet port 30 close, and increasing the disinfection uniformity.
[0045] On the side wall of the cylinder body 1, there is an air outlet 3. The air outlet 3 is provided with a filter layer 4, and a sealing member 5 is detachably connected to the air outlet 3. After disinfection is completed, the gas flows out from the air outlet 3. The filter layer 4 is provided with a catalyst, which can decompose harmful gases such as ozone generated by ionization to avoid polluting the environment.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
