An active ultrasonic vibrator 6 is arranged between the guide rail 7 and the cleaning liner 2, a connecting sleeve 61 is arranged at the bottom of the active ultrasonic vibrator 6, the outer diameter of the connecting sleeve 61 is larger than the inner width of the guide rail 7, an electromagnet 62 is fixedly installed inside the connecting sleeve 61, a guide column 63 is inserted inside the connecting sleeve 61, the guide column 63 can penetrate the guide rail 7 and be inserted into the driving sleeve 81, a top spring 64 is arranged between the guide column 63 and the electromagnet 62, a vertical guide groove 65 is opened on the inner wall of the connecting sleeve 61, two groups of protrusions 67 are arranged on the outer side of the guide column 63, the upper protrusion 67 is inserted into the vertical guide groove 65, and the lower protrusion 67 can be screwed into the spiral groove 82;

Four groups of connecting grooves 41 are provided on the outer side of the mounting plate 4. The connecting grooves 41 are arranged corresponding to the guide rails 7. The connecting sleeves 61 can be inserted into the connecting grooves 41. The inner wall of the connecting grooves 41 is provided with sliding holes. A clamping block 42 is slidably connected inside the sliding hole. A retaining spring is provided between the clamping block 42 and the inner wall of the sliding hole. The end of the clamping block 42 close to the connecting groove 41 is designed in an arc shape and has a frosted surface.

During assembly, the telescopic driving rod 8 and the fixed ultrasonic vibrator 5 are preassembled on the mounting plate 4, the linear sliding module 3 is mounted on the inner bottom of the housing 1, and then the mounting plate 4 is mounted on the slider of the linear sliding module 3, and the guide rail 7 is located between the mounting plate 4 and the linear sliding module 3, and the telescopic driving rod 8 is located below the guide rail 7, and then the movable ultrasonic vibrator 6 is placed on the guide rail 7, and the movable ultrasonic vibrator 6 is rotated, and the movable ultrasonic vibrator 6 drives the connecting sleeve 61 to rotate, and the connecting sleeve 61 drives the guide column 6 through the upper protrusion 67 and the vertical guide groove 65 3 is rotated, the guide column 63 drives the lower protrusion 67 to be screwed into the spiral groove 82, and the movable ultrasonic vibrator 6 is quickly installed. Then the cleaning liner 2 is assembled on the housing 1. There is no need to adjust the position of the movable ultrasonic vibrator 6 in advance. After the installation is completed, the telescopic driving rod 8 is controlled to rotate according to the cleaning amount and the distribution of the equipment. The telescopic driving rod 8 drives the movable ultrasonic vibrator 6 to slide along the guide rail 7 through the guide column 63, so that the layout of the movable ultrasonic vibrator 6 can be changed. No professional personnel need to adjust it. It is only necessary to control the rotation angle of the telescopic driving rod 8, which is convenient for adjustment.

When cleaning the clamp, suture device, bracket and screw, the telescopic driving rod 8 is controlled to swing to a vertical state. At this time, the telescopic driving rod 8 is completely retracted, and the telescopic driving rod 8 drives the movable ultrasonic vibrator 6 to move to the same straight line as the fixed ultrasonic vibrator 5, and the connecting sleeve 61 is inserted into the connecting groove 41. When the connecting sleeve 61 passes through the block 42, the connecting sleeve 61 pushes the block 42 to slide into the sliding hole. At the same time, due to the setting of the frosted surface, the friction between the block 42 and the connecting sleeve 61 is greater than the friction between the connecting sleeve 61 and the inner wall of the connecting groove 41. Therefore, the block 42 drives the connecting sleeve 61 to rotate, and the connecting sleeve 61 drives the guide column 63 to rotate through the upper protrusion 67 and the vertical guide groove 65, and the guide column 6 3 drives the lower protrusion 67 to rotate out of the spiral groove 82. When the connecting sleeve 61 passes through the block 42, the clamping spring pushes the block 42 to extend. In the case of no driving, the movable ultrasonic vibrator 6 will not slide out of the connecting groove 41. At this time, the control electromagnet 62 is energized, and the electromagnet 62 generates a magnetic force to drive the guide column 63 to rise. The guide column 63 is away from the guide rail 7 and the driving sleeve 81. The guide column 63 and the guide rail 7 will not affect the installation plate 4 to drive the movable ultrasonic vibrator 6 to move in a straight line. At this time, the two groups of movable ultrasonic vibrators 6 and the two groups of fixed ultrasonic vibrators 5 are located on the same straight line, which can be targeted to perform high-intensity cleaning on the clamp, suture, bracket and screw, without setting the ultrasonic vibrator to excessive power, thereby reducing costs;

When cleaning slender instruments such as surgical forceps and probes, the linear sliding module 3 is controlled to operate, the linear sliding module 3 drives the mounting plate 4 to move horizontally and linearly, and the mounting plate 4 drives the two groups of movable ultrasonic vibrators 6 and the two groups of fixed ultrasonic vibrators 5 to move horizontally and linearly, so that the ultrasonic wave can evenly reach all surfaces of the instrument and clean it comprehensively;

The mounting plate 4 is controlled to move to the middle position, and then the electromagnet 62 is powered off, the top spring 64 pushes the guide post 63 to pass through the guide rail 7 and is inserted into the drive sleeve 81, and then the telescopic drive rod 8 is controlled to rotate, and the telescopic drive rod 8 drives the connecting sleeve 61 away from the connecting groove 41 through the drive sleeve 81 and the guide post 63. When passing through the block 42, the connecting sleeve 61 drives the guide post 63 to rotate again, and the guide post 63 is screwed into the spiral groove 82, so that the movable ultrasonic vibrator 6 can remain stable even when it is away from the mounting plate 4;

In summary, the present invention can arbitrarily change the layout of the movable ultrasonic vibrator 6, is easy to use, and has high cleaning efficiency. At the same time, it can carry out targeted local enhanced cleaning and ultra-long distance cleaning, and the cleaning is comprehensive. Only low-power ultrasonic vibrators are required, thereby reducing equipment costs and subsequent cleaning energy consumption.

On the basis of the above embodiment, the present invention further includes that a transmission wheel 46 is rotatably mounted on the bottom of the mounting plate 4 , a balance wheel 83 is fixedly mounted on the bottom of the telescopic driving rod 8 , and two groups of balance wheels 83 are respectively engaged with the two sides of the transmission wheel 46 .

Furthermore, the radius of the driven wheel 45 is smaller than the radius of the transmission wheel 46 and the driving wheel 44 , and the radius of the balance wheel 83 is smaller than the radius of the transmission wheel 46 .

By controlling the driving motor 43 to be energized, the driving motor 43 drives the active wheel 44 to rotate, the active wheel 44 drives the driven wheel 45 to rotate, the driven wheel 45 drives the transmission wheel 46 to rotate, the transmission wheel 46 drives the balance wheel 83 to rotate, and the balance wheel 83 drives the telescopic driving rod 8 to rotate. Since the radius of the driven wheel 45 is smaller than the radius of the transmission wheel 46 and the active wheel 44, and the radius of the balance wheel 83 is smaller than the radius of the transmission wheel 46, by controlling the active wheel 44 to rotate a smaller angle, the telescopic driving rod 8 can be controlled to swing a larger angle, and the control is simple. At the same time, through the offset setting of the driving motor 43, the driving motor 43 will not affect the layout of the mounting plate 4, and the structure is more compact.

On the basis of the above embodiment, the guide rail 7 is further welded to the inner wall of the casing 1 through a T-shaped bracket. Through this design, the stability of the guide rail 7 can be improved.
