Description

Technical Field

[0001] This invention relates to the field of medical device disinfection equipment technology, and in particular to an ultrasonic probe disinfection device for preventing cross-infection. Background Technology

[0002] As a key component of medical ultrasound diagnostic equipment, the ultrasound probe may carry pathogenic microorganisms on its surface after use. If disinfection is not thorough, it can easily become a medium for cross-infection between patients. Currently, the most common disinfection method in clinical practice is still manual wiping, where medical staff use cotton swabs or gauze soaked in disinfectant to clean the working surface of the probe. This method involves repeatedly opening and closing the disinfectant container and manually changing cotton swabs, which increases the risk of medical staff coming into contact with contaminants. Furthermore, the amount of disinfectant used depends on personal experience; too much can easily drip, causing environmental pollution and waste, while too little will affect the disinfection effectiveness.

[0003] Some existing automated disinfection equipment attempts to improve the above problems, but they are usually simple in structure and have limited functions. They can only achieve simple linear wiping actions. However, the working surface of most ultrasonic probes is curved, and this simple wiping action cannot effectively disinfect and clean the surface of the house, which can easily lead to cleaning dead corners and disinfection failure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a disinfection device for ultrasonic probes that prevents cross-infection. This device can automatically disinfect the working area of ​​the curved surface of the ultrasonic probe and establish a closed, quantitative, and controllable disinfectant supply process to cut off potential cross-infection chains.

[0005] The objective of this invention is achieved through the following technical solution: a disinfection device for an ultrasound probe to prevent cross-infection, comprising a base component, a translation component, a multifunctional rotating frame component, and a disinfection box component;

[0006] The base component includes an operating window, the translation component includes a translation slide, the multi-functional rotating frame component includes a rotating frame, a disinfection swab, and a thrust sensor, and the disinfection box component includes a disinfection box body, a trigger guide plate, and an overlapping inclined plate. The operating window is located on one side of the main body of the base component, the disinfection box body is fixed on the other side of the main body of the base component, the translation slide is located in the main body of the base component and can slide automatically, and the rotating frame is screwed into the translation slide and can rotate automatically.

[0007] The outer frame of the rotating frame is equipped with a laser emitter, an ultraviolet lamp, and a pair of C-shaped brackets. The non-sterilized parts at both ends of the disinfectant swab are respectively clipped into different C-shaped brackets. A thrust sensor is installed between the C-shaped bracket and the main body of the rotating frame, which can monitor the thrust from the direction of the disinfectant swab.

[0008] The bottom of the disinfection box is connected to a drain nozzle. An overlapping inclined plate is fixed to the lower side of the disinfection box. The outer bottom end of the trigger guide plate is elastically and torsionally screwed to the overlapping inclined plate. When there is no external force pressing the trigger guide plate, the top of the trigger guide plate is in a position that closes the bottom outlet of the drain nozzle.

[0009] The process of using the technical solution formed by this invention is as follows:

[0010] The ultrasonic probe is clamped and positioned by a clamping mechanism on the outside of the operating window, with the working surface facing the operating window. The sliding carriage moves and the rotating carriage rotates in coordination, causing the laser emitter to extend out of the operating window. The emitted laser beam reaches the top of the probe's working surface, which can guide the clamping mechanism to determine the lateral position of the ultrasonic probe. The control system records this position as the disinfection starting point.

[0011] The process involves applying disinfectant solution, rotating the frame, and sliding the slide, which moves the disinfectant swab to a set position relative to the disinfection box assembly. As the frame rotates, it causes the C-shaped holder and the disinfectant swab to rotate, which in turn causes the disinfectant swab to press down and trigger the guide plate. The guide plate then opens the outlet of the discharge nozzle, allowing the disinfectant solution inside the disinfection box to flow out from the discharge nozzle. The outflowing disinfectant solution is evenly diffused into the disinfectant swab. The control system can also control the timing of when the disinfectant swab presses down and triggers the guide plate to achieve different degrees of disinfectant saturation in the disinfectant swab.

[0012] Automatic wiping: As the sliding carriage slides and the rotating carriage rotates, the disinfectant swabs successfully soaked in disinfectant return to the operating window. After the rotating carriage rotates and lifts the disinfectant swabs, disengaging them from the trigger guide plate, the trigger guide plate automatically returns to the position that closes the outlet of the discharge nozzle under the elastic rotational torque of the trigger guide plate itself and the overlapping inclined plate. The disinfectant swab moves to the disinfection starting point recorded by the laser emitter. Under the monitoring of the thrust sensor, the disinfectant swab contacts the working surface of the ultrasonic probe with appropriate thrust, starting from the top of the arc. The sliding carriage and the rotating carriage work together to wipe the disinfectant swab to one side until the thrust sensor detects zero thrust, indicating that the wiping of that side is complete. Then the disinfectant swab returns to the disinfection starting point and wipes the other side, ensuring full coverage of the probe's arc surface.

[0013] Before or after wiping, the rotation of the rotating frame and the sliding of the translational carriage can cause the C-shaped bracket to extend to the outside of the operating window to remove the used disinfectant swab or install a new unused disinfectant swab.

[0014] The disinfection of the internal space of the base component involves the sliding of the translational carriage and the rotation of the rotating carriage, which can move the ultraviolet lamp to different positions inside the base component, and use the ultraviolet light of the ultraviolet lamp to carry out comprehensive disinfection of the internal space of the base component.

[0015] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0016] (1) The device drives the laser emitter to extend out of the operating window through the coordinated movement of the translational carriage and the rotating carriage, accurately positioning the arc top of the working surface of the ultrasonic probe and recording it as the disinfection starting point; during disinfection, the disinfectant cotton swab soaked in disinfectant is automatically wiped from the starting point to both sides under the monitoring of the thrust sensor with a set pressure until the thrust returns to zero, ensuring that the entire arc surface of the probe is covered at once; this process avoids the need for repeated wiping due to inaccurate manual positioning or wiping omissions, ensuring that a single disinfection can achieve comprehensive cleaning and significantly reducing the probability of cross-infection;

[0017] (2) The disinfection box assembly adopts an elastic normally closed system consisting of a trigger guide plate and a discharge nozzle. The disinfectant will only flow out and wet the disinfectant cotton swab when the disinfectant cotton swab is pressed by the rotating frame. The trigger guide plate will automatically reset and seal under the action of torque. This design realizes "use and take out, close when not in use", avoiding the risk of disinfectant failure due to long-term exposure to air and the risk of contamination from contact with external pollutants, and preventing the disinfectant itself from becoming an infection medium. At the same time, the opening of the C-shaped card slot faces the trigger guide plate when pressed, ensuring that the disinfectant cotton swab is under stable force and avoiding operation contamination caused by falling off, further ensuring the cleanliness and controllability of the disinfection process.

[0018] (3) The device moves the ultraviolet lamp inside the base component by translating the slide and rotating the frame, especially focusing on irradiating easily contaminated areas such as the contact area between the disinfection cotton swab and the trigger guide plate, so as to realize autonomous ultraviolet disinfection of the internal space of the equipment and eliminate any possible residual pathogens; at the same time, it can move the C-shaped card to the outside of the operating window, which is convenient for quick replacement of the disinfection cotton swab and ensures that new consumables are used for each disinfection; this dual design not only prevents the inside of the base component from becoming a hidden source of cross-infection, but also avoids indirect contact transmission between ultrasonic probes through the single use of consumables, thus constructing a complete infection control chain from the inside to the outside.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] Example 1:

[0039] Examples of automatic disinfection of ultrasonic probes according to the present invention Figures 1-10 As shown, an operation window 105 is provided on one side of the main body of the base component 1, the disinfection box 402 is fixed on the other side of the main body of the base component 1, the translation slide 205 is provided in the main body of the base component 1 and can slide automatically, and the rotating frame 302 is screwed into the translation slide 205 and can rotate automatically.

[0040] A laser emitter 306, an ultraviolet lamp 310, and a pair of C-shaped brackets 308 are installed on the outer frame of the rotating frame 302. The non-sterilized parts at both ends of the disinfectant swab 309 are respectively clipped into different C-shaped brackets 308. A thrust sensor 313 is installed between the C-shaped bracket 308 and the main body of the rotating frame 302, and can monitor the thrust from the direction of the disinfectant swab 309.

[0041] Furthermore, the sliding of the translational carriage 205, in conjunction with the rotation of the rotating carriage 302, can cause the laser emitter 306 or the disinfectant swab 309 to extend to the outside of the operating window 105.

[0042] A clamping mechanism is provided on the outside of the operation window 105, which can stably clamp the ultrasonic probe and make the working surface of the ultrasonic probe face the side of the operation window 105.

[0043] The bottom of the disinfection box 402 is connected to a drain nozzle 404. An overlapping inclined plate 407 is fixed to the lower side of the disinfection box 402. The outer bottom end of the trigger guide plate 405 is elastically and torsionally screwed to the overlapping inclined plate 407. When there is no external force pressing the trigger guide plate 405, the top end of the trigger guide plate 405 is in a position that closes the bottom outlet of the drain nozzle 404.

[0044] Furthermore, the sliding of the translational slide 205, combined with the rotation of the rotating frame 302, can also move the disinfectant swab 309 to the top of the trigger guide plate 405, and can overcome the torque of the elastic screw connection between the trigger guide plate 405 and the fixed base 409, causing the trigger guide plate 405 to separate from the outlet of the discharge nozzle 404, so that the disinfectant in the disinfection box 402 flows from the discharge nozzle 404 to the surface of the disinfectant swab 309 that is against the top groove of the trigger guide plate 405, forming a coating of disinfectant on the disinfectant swab 309 before cleaning;

[0045] The working principle is as follows:

[0046] The device achieves comprehensive disinfection of the ultrasound probe through automatic positioning, dipping in disinfectant, and automatic wiping.

[0047] The ultrasonic probe is clamped and positioned by a clamping mechanism on the outside of the operating window 105, with the working surface facing the operating window 105. The sliding carriage 205 slides and rotates in coordination with the rotating carriage 302, which drives the laser emitter 306 to extend out of the operating window 105. The emitted laser beam reaches the top of the probe's working surface, which can guide the clamping mechanism to determine the lateral position of the ultrasonic probe. The control system records this position as the disinfection starting point.

[0048] The disinfectant solution is applied by rotating the frame 302 and sliding the slide 205, which moves the disinfectant swab 309 to a set position relative to the disinfection box assembly 4. As the frame 302 rotates, it causes the C-shaped card holder 308 and the disinfectant swab 309 to rotate, which in turn causes the disinfectant swab 309 to press down and trigger the guide plate 405. The guide plate 405 opens the outlet of the discharge nozzle 404, allowing the disinfectant solution in the disinfection box 402 to flow out from the discharge nozzle 404. The outflowing disinfectant solution is evenly diffused into the disinfectant swab 309. The control system can control the time when the disinfectant swab 309 presses down and triggers the guide plate 405 to achieve different degrees of disinfectant solution immersion in the disinfectant swab 309, which can avoid the disinfectant swab 309 from absorbing too much disinfectant solution and eliminate the risk of disinfectant solution dripping during the transfer of the disinfectant swab 309.

[0049] Furthermore, to further eliminate the risk of disinfectant dripping, the disinfectant swab 309 adopts a double-layer composite design. The inner layer is made of a material with excellent water absorption and water retention (such as fiber), and the outer layer is made of a material with excellent hydrophilicity and water-locking ability (such as non-woven fabric).

[0050] Furthermore, when the disinfectant swab 309 presses down on the trigger guide plate 405, the opening of the C-shaped bracket 308 faces the trigger guide plate 405, so that the C-shaped bracket 308 drives the disinfectant swab 309 to press down on the trigger guide plate 405, thus avoiding the risk of the disinfectant swab 309 and the C-shaped bracket 308 coming off.

[0051] Automatic wiping: As the sliding carriage 205 slides and the rotating carriage 302 rotates, the disinfectant swab 309, successfully soaked in disinfectant, returns to the operation window 105. After the rotating carriage 302 rotates and lifts the disinfectant swab 309, disengaging it from the trigger guide plate 405, the trigger guide plate 405 automatically returns to the position that closes the outlet of the discharge nozzle 404 under the elastic rotational torque of the trigger guide plate 405 itself and the overlapping inclined plate 407. The disinfectant swab 309 then moves to the disinfection starting point recorded by the laser emitter 306. Under the monitoring of the thrust sensor 313, the disinfectant swab 309 contacts the working surface of the ultrasonic probe with appropriate thrust. Starting from the top of the arc, the translation slide 205 and the rotating frame 302 work together to drive the disinfectant swab 309 to wipe to one side until the thrust detected by the thrust sensor 313 is zero, indicating that the wiping of that side is complete. Then the disinfectant swab 309 returns to the disinfection starting point and wipes to the other side, ensuring full coverage of the probe arc surface. The disinfectant swab 309 itself has a certain elasticity and can form a certain range of movement error.

[0052] When replacing the disinfectant cotton swab 309, before or after wiping, the rotating bracket 302 and the sliding carriage 205 can drive the C-shaped card holder 308 to extend to the outside of the operation window 105 to remove the used disinfectant cotton swab 309 or install a new unused disinfectant cotton swab 309.

[0053] The disinfection of the internal space of the base component 1 is achieved by sliding the translational carriage 205 and rotating the rotating carriage 302, which can move the ultraviolet lamp 310 to different positions inside the base component 1. The ultraviolet light of the ultraviolet lamp 310 is used to thoroughly disinfect the internal space of the base component 1. In addition, the ultraviolet lamp 310 can also be moved to the position where the disinfection cotton swab 309 contacts the trigger guide plate 405, so as to focus on disinfecting the positions where cross-infection is likely to occur. This can be achieved by extending the ultraviolet irradiation time.

[0054] The specific structures of base component 1, translation component 2, and multi-functional rotating frame component 3 are as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the top of the base frame 101 is fixedly connected to the bottom of the base 102, and the outer side of the base 102 is covered by the main cover 103, and the bottom of the main cover 103 has a through hole to eliminate interference with the base frame 101.

[0055] The cover plate 104 is attached to one side of the main housing 103, and the operating window 105 is opened in the main body of the cover plate 104;

[0056] An external connector 106 is fixedly connected to one side of the base 102. Similarly, the main body of the cover plate 104 has through holes to eliminate interference with the external connector 106.

[0057] Inside the base 102, a pair of uprights 201 are fixedly connected, and a pair of guide posts 202 are connected between the uprights 201. The translation slide 205 is slidably connected to the guide posts 202 through the guide slider 206.

[0058] Each set of support 201 has a translation screw seat 204 installed and fixed in its main body. The two ends of the translation screw 203 are respectively screwed into different translation screw seats 204. The outer side of the translation slide 205 is fixed with a translation screw slider 207, which is connected to the translation screw 203. The base 102 has a translation servo motor 208 installed and fixed inside. The outer end of the translation screw 203 is fixed to the shaft of the translation servo motor 208.

[0059] By starting the translation servo motor 208 through the control system, the translation screw 203 and the translation screw slider 207 are engaged, which enables the translation carriage 205 to move automatically guided by the engagement of the guide slider 206 and the guide post 202.

[0060] A main rotating seat 301 is fixedly installed in the main body of the translation slide 205. The rotating shaft in the middle of the main body of the rotating carriage 302 is spun to the main rotating seat 301. A rotating servo motor 315 is installed and fixed inside the translation slide 205. The end of the rotating shaft in the middle of the rotating carriage 302 is fixedly connected to the rotating shaft of the rotating servo motor 315.

[0061] Furthermore, the engagement between the rotary servo motor 315 and the rotary frame 302 will not interfere with the sliding engagement between the guide slider 206 and the guide post 202;

[0062] A pair of position detection arms 303 are fixed on the outer frame of the rotating frame 302. The laser emitter 306 and the receiving lens 307 are respectively installed at the head end of different position detection arms 303. The purpose of setting the receiving lens 307 on one side of the laser emitter 306 is to effectively terminate the laser beam and eliminate the reflection phenomenon of the laser on other objects.

[0063] A pair of ultraviolet lamp holders 305 are fixed on the outer frame of the rotating bracket 302, and the two ends of the ultraviolet lamp 310 are respectively fixed in different ultraviolet lamp holders 305;

[0064] The main body of the rotating frame 302 is provided with a sliding groove 312, and a buffer slide 311 is fixed between the tail ends of the pair of disinfection connecting arms 304. The buffer slide 311 is slidably connected to the sliding groove 312, and a C-shaped card seat 308 is provided at the head end of the disinfection connecting arm 304.

[0065] The thrust sensor 313 is mounted and fixed on one side of the buffer slide 311. One end of the buffer spring 314 is fixed to the side of the thrust sensor 313, and the other end is fixed to one side of the inner surface of the slide groove 312.

[0066] Furthermore, in the naturally extended state of the buffer spring 314, the other side of the buffer slide 311 is in a position that does not fit against the other side of the inner surface of the slide groove 312. Only when the disinfectant cotton swab 309 is pushed by an external force can the buffer spring 314 contract.

[0067] By introducing an elastic floating mechanism consisting of a buffer slide 311, a slide groove 312, and a buffer spring 314, compared to directly installing the thrust sensor 313 between the C-shaped card holder 308 and the rotating frame 302, adaptive buffering and overload protection can be provided, improving the safety and reliability of the device.

[0068] The specific structure of disinfection box component 4 is as follows: Figure 7 , Figure 8 and Figure 9 As shown, the bottom box 401 is fixed to the other side inside the base 102. The bottom end of the disinfection box 402 is fixed to the top side of the bottom box 401. The liquid filling pipe 403 is connected to the top of the disinfection box 402 and extends to the outside through the side wall of the main cover 103 for replenishing disinfectant into the disinfection box 402. A cap is installed at the inlet of the liquid filling pipe 403.

[0069] The overlapping inclined plate 407 is fixed to the inner surface of the other side of the bottom box 401. The waste liquid discharge pipe 406 is connected to the side wall of the bottom box 401, and the inlet position is connected to the top area of ​​the overlapping inclined plate 407. The outlet position extends to the outside after passing through the side wall of the main cover 103. The space formed by the top inclined surface of the overlapping inclined plate 407 and the inner cavity of the bottom box 401 is used to collect the trace amount of disinfection waste liquid after the disinfection cotton swab 309 is soaked. A collection container is placed on the inner bottom surface of the bottom frame 101 to collect the disinfection waste liquid discharged from the waste liquid discharge pipe 406.

[0070] Regardless of whether the trigger guide plate 405 is closed or open at the bottom outlet of the discharge nozzle 404, the liquid can be smoothly discharged to the top slope of the overlapping inclined plate 407.

[0071] A fixed rotating seat 409 is fixedly connected to the inner side of the bottom end of the overlapping inclined plate 407, and a movable rotating seat 413 is fixedly connected to the outer bottom end of the trigger guide plate 405. A fixed trigger rotating shaft 410 is inserted into the fixed rotating seat 409, and the movable rotating seat 413 is screwed to the trigger rotating shaft 410. A torsion spring 411 is sleeved in the trigger rotating shaft 410, and one side is fixed to the bottom end of the overlapping inclined plate 407, and the other side is fixed to the outer bottom end of the trigger guide plate 405.

[0072] The torsion spring 411 can generate an elastic torque on the trigger guide plate 405 to close the bottom outlet of the discharge nozzle 404, so that when there is no external force pushing, the trigger guide plate 405 is always in the position of closing the bottom outlet of the discharge nozzle 404.

[0073] A sealing gasket 408 is fixed at the top of the trigger guide plate 405 near the discharge nozzle 404. After the sealing gasket 408 elastically contracts, it is flush with the top surface of the trigger guide plate 405, which can form a good sealing effect on the bottom outlet of the discharge nozzle 404 without affecting the flow of disinfectant liquid.

[0074] On the other side of the top of the bottom box 401, a pair of limiting grooves 412 are provided to limit the disinfection arm 304 as it rotates with the rotating frame 302, so that when the disinfection arm 304 rotates to abut against the bottom of the limiting groove 412, the disinfection cotton swab 309 can safely and reliably press the trigger guide plate 405 down to the open position.

[0075] Example 2:

[0076] like Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the clamping mechanism for holding the ultrasound probe consists of an opening and closing clamping assembly 6 and an adjustable clamping plate assembly 7. Opening and closing slides 601 are fixedly connected to both sides of the head cavity of the outer connecting seat 106. The symmetrically distributed opening and closing plates 602 are slidably connected to the opening and closing slides 601. An opening and closing motor 603 is installed and fixed in the tail cavity of the outer connecting seat 106 to drive the opening and closing action of the opening and closing plates 602. A special-shaped cover 604 is attached to the top of the tail cavity of the outer connecting seat 106.

[0077] Each side of the opening and closing plate 602 is fixed with a pair of opening and closing sliding pillars 606, and there is a certain distance between the opening and closing sliding pillars 606 installed on different sides of the opening and closing plate 602. The opening and closing slide block 601 and the opening and closing sliding pillar 606 are both fixed with a sliding sleeve 605 installed at the position opposite to each other. The opening and closing sliding pillar 606 and the sliding sleeve 605 on the same side are slidably connected.

[0078] On the same side, the other ends of the opening and closing slide column 606 are fixedly connected to opposing connecting seats 607. Each pair of opposing connecting seats 607 has an opening and closing rack 608 fixedly connected to its inner side. An opening and closing shaft seat 610 is installed and fixed in the head end cavity wall of the outer connecting seat 106. The opening and closing shaft 611 is screwed into the opening and closing shaft seat 610. The opening and closing gear 609 is inserted into the inner end of the opening and closing shaft 611 and meshes with the opening and closing rack 608. The outer end of the opening and closing shaft 611 is connected to the rotating shaft of the opening and closing motor 603. The main body of the opening and closing slide 601 has a through hole for eliminating interference with the opening and closing rack 608.

[0079] After the opening and closing motor 603 is started and the opening and closing gear 609 is driven to rotate, the opening and closing gear 609 can form a transmission with the opening and closing racks 608 on both sides, thereby driving the symmetrically distributed opening and closing plates 602 to form a synchronous opening and closing action.

[0080] Furthermore, within the stroke range of the opening and closing action of the opening and closing plate 602, the opposing connecting seat 607 will neither come into contact with the opening and closing slide 601 nor with the opening and closing plate 602.

[0081] Each set of opening and closing plates 602 is equipped with an adjustable clamping plate assembly 7. The other side of the opposite side of each opening and closing plate 602 is fixedly connected with a pair of adjusting main rotating seats 711. The adjusting main rotating shaft 712 is inserted between the adjusting main rotating seats 711. The clamping plate 701 and the opposing clamping plate 702 are both screwed into the adjusting main rotating shaft 712. The opposing clamping plate 702 has a groove in its main body so that the screwing position of the clamping plate 701 and the adjusting main rotating shaft 712 will not interfere with the screwing position of the opposing clamping plate 702 and the adjusting main rotating shaft 712.

[0082] Both the inner sides of the clamping plate 701 and the opposing clamping plate 702 are fixed with rubber pads 703, and the rubber pads 703 have a certain thickness and elasticity, which can flexibly and safely clamp the handle of the ultrasonic probe.

[0083] A passive rotating seat 709 is fixed on the outer side of both the clamping plate 701 and the opposing clamping plate 702. An adjusting screw rotating seat 705 is fixedly installed in the main body of each set of opening and closing plates 602. The adjusting screw 706 is connected in the adjusting screw rotating seat 705. The inner connecting seat 707 is screwed to the inner end of the adjusting screw 706. Both ends of each set of inner connecting seats 707 are fixed with ear seats 708. A connecting rod 710 is connected between the ear seat 708 on the same side and the passive rotating seat 709. One end of the connecting rod 710 is screwed to the ear seat 708 and the other end is screwed to the passive rotating seat 709.

[0084] Angle adjustment motor 704 is mounted and fixed on the outer side of opening and closing plate 602, screw slide 713 is fixed to the outer end of the rotating shaft of angle adjustment motor 704, and the outer end of adjustment screw 706 is slidably connected to screw slide 713.

[0085] The start-up angle adjustment motor 704 drives the rotation of the lead screw slide 713. Utilizing the sliding engagement between the lead screw slide 713 and the outer end of the adjusting lead screw 706, the adjusting lead screw 706 can be rotated, and the adjusting lead screw 706 can also engage with the adjusting lead screw rotating seat 705. This results in the adjusting lead screw 706 moving with the adjusting lead screw rotating seat 705 as a reference, which in turn moves the inner connecting seat 707 and the ear seat 708. Using the connecting rod 710 screwed between the ear seat 708 and the passive rotating seat 709, the clamping plate 701 and the opposing clamping plate 702 can be rotated synchronously to adjust the angle, thereby causing a change in the relative angle between the clamping plate 701 and the opposing clamping plate 702.

[0086] A torque sensor is installed between the rotating shaft of the opening and closing motor 603 and the opening and closing shaft 611. The torque sensor is set to a preset torque threshold. The clamping force corresponding to this threshold is sufficient to prevent the ultrasonic probe from moving or shaking during subsequent wiping, and is far below the force that may damage the ultrasonic probe. When the output torque of the opening and closing motor 603 reaches this preset threshold, the control system immediately determines that the clamping is complete and stops the opening and closing motor 603. At this time, the clamping force is precisely locked at the target value. At the same time, the elasticity of the rubber pad 703 further buffers and evenly distributes this clamping force, ensuring non-destructive clamping. This enables stable clamping of ultrasonic probe handles of different specifications and curved shapes, ensuring that the subsequent automated disinfection process can be accurate, comprehensive, and free from cross-contamination.

[0087] Preferred, such as Figure 10 As shown, a waste disposal component 5 is installed in the bottom wall of the main housing 103 for the automatic discharge of used disinfectant cotton swabs 309. A pair of abutment posts 502 are fixed to the inner wall of the bottom end of the main housing 103. The disposal hopper 501 is located on one side of the abutment posts 502, and its top inlet communicates with the inner cavity of the main housing 103. This allows the sliding of the translational slide 205 and the rotation of the rotating frame 302 to move the used disinfectant cotton swabs 309 towards the abutment posts 502. The rotation causes the non-sterilized part of the disinfectant swab 309 to abut against the abutment 502. As the rotating frame 302 continues to rotate, it can overcome the clamping force of the C-shaped holder 308 on the end of the disinfectant swab 309, and release the disinfectant swab 309 from the C-shaped holder 308. Under the action of gravity, it is discharged through the disposal hopper 501. The inner bottom surface of the base frame 101 is provided with a waste collection container for collecting the disinfectant swabs 309 discharged from the disposal hopper 501.

[0088] The driving components (such as motors), sensors (such as thrust sensor 313, laser emitter 306), and ultraviolet lamps 310 in the translation component 2, multi-functional rotating frame component 3, disinfection box component 4, and clamping mechanism (opening and closing clamping component 6 and adjustable clamping plate component 7) mentioned in the above embodiments are all electrically connected to the control system installed inside the main housing 103. This control system can receive sensor signals and send control commands to each driving component according to a preset program, thereby coordinating and completing a series of automated operations such as automatic positioning, clamping, disinfectant supply, wiping, and internal disinfection of the ultrasonic probe. The human-machine interface (such as a touch screen) integrated into the control system is used for parameter setting and status display. Those skilled in the art will understand that this control system and its programming implementation are conventional applications of existing technology, and its specific hardware selection and software logic can be adapted and developed according to actual functional requirements, and are not the inventive point of this invention. The core innovation of this invention lies in the aforementioned unique mechanical structure and mutual cooperation relationship; the control system is a conventional technical means serving this mechanical scheme and enabling automation.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions 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.
