[0010] Furthermore, the driving mechanism further comprises a final position magnet, and the final position magnet and the slider of the slider cylinder are magnetically repelled.

[0011] Furthermore, a torsion spring and a rotating rod are provided at the intersection of the slide bar and the cross bar. The rotating rod is inserted into the connecting hole of the slide bar and the cross bar, and the torsion spring is sleeved on the rotating rod.

[0012] Furthermore, one end of the driving rod extending out of the speed regulating device is a protruding end, and the first placing tube pushes the protruding end to make the driving rod slide.

As the endless belt moves, the first placement tube contacts and pushes the driving rod to slide and trigger the speed regulating device. The motor is controlled by the speed regulating device to reduce its speed. At this time, the conveying speed of the surgical knife is reduced, so that the air nozzle can blow on the surgical knife for a longer time, so that the surgical knife can be cleaned more thoroughly. The endless belt drives the first placement tube to finally break away from contact with the driving rod, thereby resetting the driving rod and restoring the speed of the motor. At this time, the conveying device restores its original conveying speed.

[0032] Embodiment 1

[0033] like Figure 1-Figure 6As shown, a cleaning device for a surgical electrosurgical knife includes a conveying device 100, a speed regulating device 200 and a following device 300. The conveying device 100 includes an annular belt 110 formed by an upper belt and a lower belt, a first placement cylinder 120 arranged on the upper belt and a second placement cylinder 130 arranged on the lower belt. The speed regulating device 200 is used to control the rotation speed of the annular belt 110. The speed regulating device 200 is provided with a driving rod 210. When the first placement cylinder 120 moves toward the speed regulating device 200, the driving rod 210 is triggered to reduce the rotation speed of the speed regulating device 200. The following device 300 includes an air nozzle 310. The air nozzle 310 acts on the second placement cylinder 130 and rotates to change the air outlet direction within a distance threshold range as the second placement cylinder 130 moves.

[0034] The working mechanism of the cleaning device of the surgical electrosurgical knife provided in this embodiment is as follows:

[0035] When in use, the surgical knife is placed in the second placement tube 130. When the surgical knife installed in the tube moves to the blowing position of the air nozzle 310, the first placement tube 120 can move to a position close to the driving rod 210. As the annular belt 110 moves, the first placement tube 120 contacts and pushes the driving rod 210 to slide and trigger the speed regulating device 200. The motor is controlled by the speed regulating device 200 to reduce its speed. At this time, the conveying speed of the surgical knife is reduced, so that the air nozzle 310 can blow on the surgical knife for a longer time, so that the surgical knife can be cleaned more thoroughly. The annular belt 110 drives the first placement tube 120 to finally break away from the contact with the driving rod 210, so that the driving rod 210 is reset, so that the speed of the motor is restored, and the conveying device 100 restores its original conveying speed. Compared with manual cleaning, safety and thoroughness can be guaranteed.

[0036] The cleaning device combines the conveying device 100, the air nozzle 310 and the speed regulating device 200 to realize automatic sensing and speed regulating cleaning of the surgical knife during movement, thereby improving the cleaning efficiency and quality, reducing the complexity and risk of manual operation, and providing a more convenient, efficient and safe solution for cleaning the surgical knife. Regarding the structure of the conveying device 100, specifically:

[0037] The conveying device 100 also includes two supports, which are symmetrically arranged on the workbench. Rollers are connected to the two supports. The annular belt 110 is connected to the two rollers, and one of the rollers is connected to the output end of the motor.

[0038] The conveying device 100 includes a workbench, and two supports are symmetrically connected at both ends of the workbench. The motor drives one of the rollers to rotate, and this roller drives the other roller to rotate through the circular belt 110, so that the circular belt 110 runs and can transport the surgical knife. There is a distance between the circular belt 110 and the workbench, so that the surgical knife can move on the upper part of the workbench and the surgical knife can be blown by the air nozzle 310 on the workbench.

[0039] Regarding the structure of the speed regulating device 200, specifically:

[0040] The speed regulating device 200 also includes a bracket, which is connected to a support at the forward direction of the first placement cylinder 120 on the upper part of the endless belt 110, the adjusting coil 220 is connected to the bracket, and the driving rod 210 slides on the bracket; the end of the driving rod 210 is connected to a limiting plate 230, and a tension spring 240 is sleeved on the driving rod 210, and the two ends of the tension spring 240 are respectively against the limiting plate 230 and the bracket.

[0041] The bracket is set on a support in the forward direction of the first placement cylinder 120 on the upper part of the circular belt 110. When the first placement cylinder 120 pushes the driving rod 210 to slide, the tension spring 240 is stretched and elongated by the sliding of the driving rod 210 and has elastic potential energy. As the circular belt 110 continues to move, the first placement cylinder 120 can eventually break away from the contact with the driving rod 210, and then the tension spring 240 elastically recovers, so that the driving rod 210 is reset. At this time, the speed of the motor is restored, thereby ensuring that the surgical electrosurgical knife can be delivered in time after cleaning.

[0042] Regarding the structure of the following device 300, specifically:

[0043] The following device 300 is also included. The following device 300 includes two rotating shafts symmetrically connected to the workbench. Two air nozzles 310 are respectively connected to the two rotating shafts. When the surgical knife moves to the lower part of the endless belt 110, the rotating shaft rotates so that the air nozzles 310 follow and blow toward the surgical knife. A passive cylinder 331 is connected to the upper surface of the workbench. The output end of the passive cylinder 331 is connected to a double rack 332. Circular gears 333 are connected to the two rotating shafts. The two circular gears 333 are meshed with the double racks 332. When the passive cylinder 331 is extended, the double racks 332 are meshed with each other. 32 slides and drives the two circular gears 333 to rotate synchronously and in opposite directions; a slider cylinder 321 is connected to the support at the forward direction of the placement cylinder, and an air pipe is connected between the slider cylinder 321 and the passive cylinder 331. When the second placement cylinder 130 moves to the blowing range of the air nozzle 310, the slider cylinder 321 shortens to extend the passive cylinder 331; a slider is fixedly connected to the support at the forward direction of the second placement cylinder 130, and a slide rod 323 is slidably connected to the slider, and a final magnet 324 is connected to the end of the slide rod 323, and a contact with the final magnet is arranged on the slider. The slider magnet 324 repels each other, the cylinder body of the slider cylinder 321 is fixedly connected to the slider, the cylinder rod of the slider cylinder 321 is fixedly connected to the final magnet 324, when the slide bar 323 is not subjected to force, the final magnet 324 repels the slider magnet to make the slider cylinder 321 extend; the following device 300 also includes a cross bar 322, which is rotatably connected to the end of the slide bar 323, and when the placement cylinder moves, the cross bar 322 can be pushed to make the slide bar 323 slide, thereby shortening the slider cylinder 321; the slide bar 323 is rotatably connected to a rotating rod 325, and the cross bar 325 is rotatably connected to the slide bar 323. 22 is fixedly connected to the rotating rod 325, and a torsion spring 326 is connected between the rotating rod 325 and the sliding rod 323. The torsion force of the torsion spring 326 is higher than the repulsive force between the last magnet 324 and the slider magnet. Therefore, after the slider cylinder 321 is completely shortened, the cross bar 322 continues to move to push the cross bar 322 to rotate relative to the sliding rod 323. After the cross bar 322 rotates relative to the sliding rod 323 and resets, the placement cylinder located on the upper part of the endless belt 110 is separated from the driving rod 210, so that the driving rod 210 is reset, the motor speed is restored, and the surgical electric knife is separated from the blowing range of the air nozzle 310.

[0044] In order to improve the cleaning effect of the surgical electrosurgery, the device is also provided with a following device 300. The setting of the following device 300 enables the air outlet of the air nozzle 310 to follow the surgical electrosurgery for blowing and cleaning. Specifically, when the second placement tube 130 drives the surgical electrosurgery to move, the second placement tube 130 can contact and push the cross bar 322. Since the torque of the torsion spring 326 is greater than the repulsive force between the final magnet 324 and the slider magnet, the placement tube first pushes the cross bar 322 to make the slide bar 323 slide relative to the slider. At this time, the final magnet 324 pushes the cylinder rod of the slider cylinder 321 to shorten, so that the gas in the slider cylinder 321 is transmitted to the passive cylinder 331 through the air pipe. At this time, the cylinder rod of the passive cylinder 331 is extended, so that the double rack 332 drives the two gears to rotate synchronously and in the opposite direction. At this time, the two shafts rotate synchronously, so that the air nozzle 310 After the second placing cylinder 130 continues to move out of contact with the cross bar 322, the torsion spring 326 elastically recovers, and then the repulsive force between the last magnet 324 and the slider magnet causes the sliding bar 323 to reset, thereby extending the slider cylinder 321 and resetting the air nozzle 310 to prepare for the next cleaning. In addition, in order to enhance the resetting effect of the sliding bar 323, a spring can be set between the last magnet 324 and the slider to ensure the resetting effect of the sliding bar 323.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
