Description

Technical Field

[0001] This invention relates to a cleaning device, specifically a multi-angle rotating spray cleaning device for surgical instruments, belonging to the technical field of cleaning devices. Background Technology

[0002] Thorough cleaning of surgical instruments is a core pre-process of medical device disinfection and sterilization. It is also a key step in avoiding cross-infection in hospitals, ensuring surgical safety, and extending the service life of precision surgical instruments. With the rapid development of minimally invasive surgery and precision medicine, the structure of surgical instruments used in clinical practice is becoming increasingly precise and complex. Therefore, extremely high technical requirements are placed on the comprehensiveness, thoroughness, and completeness of surgical instrument cleaning.

[0003] However, most existing cleaning devices have various problems. For example, in the surgical instrument cleaning device disclosed in publication number CN117102126A, although it solves the problems of weak cleaning power, water waste and cross-contamination of existing cleaning devices when cleaning medical instruments, in this technical solution and most current cleaning devices, conventional spray cleaning devices mainly rely on fixedly arranged spray nozzles to form directional water flow within a preset plane range, which has a basic cleaning effect on regular and flat instrument surfaces and can meet the routine cleaning needs of simple surgical instruments. However, most existing spray structures are fixed installations, and the spray angle and rinsing range are limited to a single fixed plane, making it impossible to achieve multi-angle rinsing. The rinsing force is seriously insufficient, and it is easy to create a large number of cleaning dead corners. As a result, stubborn contaminants remaining in the gaps and cavities of instruments cannot be thoroughly rinsed away by the water flow, leading to the accumulation of contaminant residues, subsequent bacterial growth, and a significant increase in the risk of nosocomial infections. This cannot meet the industry standards for medical device cleaning and sterilization. Medical staff often need to manually flip and adjust the placement angle of instruments, or even rework them for cleaning. This not only significantly reduces the automation level and work efficiency of the cleaning operation and increases labor costs and the workload of medical staff, but also makes it easy for the cleaning quality to be inconsistent due to differences in manual operation, and the cleaning stability is difficult to guarantee. Summary of the Invention

Example

[0019] like Figures 1 to 8 As shown, a multi-angle rotating spray cleaning device for surgical instruments includes a cleaning tank 1, a support frame 2, and a cleaning mechanism 3. The support frame 2 is fixed at the top edge of the cleaning tank 1. The cleaning mechanism 3 is installed on the support frame 2 and includes a guide tube 31, a first nozzle 32, a guide plate 33, a first conduit 34, a docking frame 35, a linkage plate 36, a card holder 37, a second nozzle 38, and a second conduit 39. The guide tube 31 is vertically set and slidably connected to the support frame 2, and is coaxially set with the cleaning tank 1. The nozzle 32 is fixed at the bottom end of the guide tube 31. The guide plate 33 is rotatably connected to the top end of the guide tube 31 through a sealed bearing. One end of the guide tube 34 is connected to the guide plate 33, and the other end is connected to the external guide device. The docking frame 35 is rotatably connected to the bottom of the support frame 2, and the guide tube 31 slides through the center of the docking frame 35. The linkage plate 36 is rotatably connected to the end of the docking frame 35. The card seat 37 is fixed to one end of the linkage plate 36 and rotatably locked to the outside of the guide tube 31. The nozzle 38 is fixed to the other end of the linkage plate 36, and a cavity is provided inside the linkage plate 36. One end of the guide tube 39 is fixed to the linkage plate 36, and the cavity is connected to the nozzle 38 and the guide tube 39. The other end of the guide tube 39 is fixed to the guide tube 31 and is connected to the cavity inside the guide tube 31. The cleaning mechanism 3 also includes a driven gear 310, a driven rod 311, and a linkage gear 312. The driven gear 310 is rotatably connected to the support frame 2, and the guide tube 31 slides through the axis of the driven gear 310. The driven rod 311 is vertically set and rotatably connected to one side of the support frame 2. The linkage gear 312 is coaxially fixed to the bottom end of the driven rod 311 and meshes with the driven gear 310. The outer wall of the guide tube 31 is axially fixed with strip-shaped protrusions, and the strip-shaped protrusions are slidably engaged with the docking frame 35 and the driven gear 310 respectively. The cleaning mechanism 3 also includes an active rod 314, an adjusting plate 316, a passive rod 317, and an abutting rod 318. The active rod 314 is vertically arranged and rotatably connected to the support frame 2, and is coaxially arranged on the top of the guide tube 31. The adjusting plate 316 is coaxially fixed to the bottom of the active rod 314, and an arc-shaped protrusion is provided at the bottom edge of the adjusting plate 316. One end of the passive rod 317 is rotatably connected to the support frame 2. There are two abutting rods 318, and the two abutting rods 318 are respectively fixed on the upper and lower sides of the passive rod 317. One abutting rod 318 slides against the bottom edge of the adjusting plate 316, and the other abutting rod 318 slides against the top of the guide tube 33. A drive gear 315 is coaxially fixed on the drive rod 314, and a driven gear 313 is coaxially fixed at the top of the driven rod 311. The driven gear 313 meshes with the drive gear 315.

[0020] This invention employs an integrated water supply structure. External water is introduced into the guide tube 31 via conduit 34 and guide plate 33, and then supplied to the nozzle 38 at the end of the linkage plate 36 via conduit 39, achieving a shared water path for both nozzles. Through the meshing transmission of the active rod 314, active gear 315, driven gear 313, and driven rod 311, the linkage gear 312 and passive gear 310 are driven to rotate.

No manual adjustment of instruments or spray angle is required. The transmission is precise and the operation is stable, effectively improving the level of automation in cleaning. Relying on the engagement of the adjustment plate 316, passive rod 317, and two sets of abutment rods 318, the working position of the guide plate 33 and the overall spray structure can be finely adjusted. During the cleaning process, the spray height and rotation amplitude are changed simultaneously, forming a three-dimensional spray structure in the axial and circumferential directions, which greatly improves the cleaning efficiency and cleanliness of surgical instruments. Example

[0021] like Figures 1 to 8 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: A reset spring 4 is fitted on the outside of the guide tube 31. One end of the reset spring 4 is fixed to the docking frame 35, and the other end is fixed to the guide tube 31. The automatic reset of the guide tube 31 and the auxiliary spray components is achieved by relying on the spring force.

[0022] A liquid outlet pipe 5 is fixed at the bottom axis of the cleaning tank 1. The liquid outlet pipe 5 is connected to the internal cavity of the cleaning tank 1, and an isolation cover plate 6 is rotatably connected to one side of the liquid outlet pipe 5. The front end of the isolation cover plate 6 is sealed against the bottom end of the liquid outlet pipe 5, which can realize the centralized and rapid discharge of cleaning wastewater and prevent waste liquid from accumulating and remaining in the tank. At the same time, with the rotatable isolation cover plate 6, the bottom end of the liquid outlet pipe 5 can be sealed and plugged. During the cleaning operation, the liquid outlet channel is closed to ensure the stability of the water pressure and cleaning environment in the cleaning tank 1 and prevent water leakage and pressure loss during high-pressure spraying. After cleaning, the drainage can be opened, effectively balancing the cleaning sealing and drainage convenience.

[0023] A cylinder 7 is installed on one side of the isolation cover 6. The telescopic end of the cylinder 7 is rotatably connected to the tail end of the isolation cover 6, and the fixed end of the cylinder 7 is rotatably connected to the cleaning tank 1, so as to realize the automatic opening and closing control of the isolation cover 6. There is no need for manual opening and closing of the cover. It can be matched with the automated cleaning process of the equipment, realize the intelligent switching of drainage and sealing processes, and the action response is stable and highly controllable, further improving the overall automation level and operation efficiency of the device.

[0024] The outer wall of the guide tube 31 is recessed with an annular groove 8, and the mounting base 37 is provided with a positioning rod 9. The positioning rod 9 is slidably engaged in the annular groove 8, which not only ensures that the mounting base 37 can rotate and slide smoothly with the guide tube 31, effectively avoiding jamming and deviation, but also limits the radial deviation of the linkage plate 36, improves the motion stability of the nozzle 38 during the rotation spraying process, and ensures that the multi-angle spraying action is stable and reliable.

[0025] The bottom of the guide tube 31 is fixed with an inclined connecting pipe 10, which is connected to the internal cavity of the guide tube 31. The connecting pipe 10 has threads on its inner wall. The back of the nozzle 32 is coaxially fixed with a threaded pipe 11. The threaded pipe 11 is detachably screwed into the connecting pipe 10 through the threads, so that the nozzle 32 forms a detachable installation structure. It is convenient to disassemble and assemble, and it is easy for staff to regularly disassemble, clean, unclog and replace the nozzle 32. It can effectively avoid the nozzle clogging affecting the spraying effect, reduce the difficulty of equipment maintenance, and at the same time, the threaded connection has good sealing performance, which can prevent water leakage and pressure loss at the connection.

[0026] Working principle: When using this cleaning device, the external cleaning fluid is introduced into the equipment through the first conduit 34, and then introduced into the internal cavity of the guide tube 31 through the guide plate 33. Part of the cleaning fluid is directly delivered to the first nozzle 32 at the bottom of the guide tube 31 to form an axial vertical spray water flow; the other part of the cleaning fluid is introduced into the internal cavity of the linkage plate 36 through the second conduit 39, and finally delivered to the second nozzle 38 to achieve synchronous water supply from the two nozzles. Then, the active rod 314 drives the active gear 315 to rotate, and the gear meshing drives the driven gear 313 and the driven rod 311 to rotate synchronously, so that the linkage gear 312 at the bottom of the driven rod 311 drives the passive gear 310 to rotate; with the help of the strip-shaped protrusion on the outer wall of the guide tube 31 slidingly engaging with the passive gear 310 and the docking frame 35, the guide tube 31 is driven to rotate and slide as a whole, and at the same time, the linkage plate 36 and the nozzle 38 at the end, which are connected to the outside of the guide tube 31 by the card seat 37, rotate and swing synchronously around the guide tube 31. Meanwhile, when the active rod 314 rotates, it can drive the adjustment plate 316 at the bottom to rotate synchronously. The arc-shaped protrusion at the bottom of the adjustment plate 316 abuts against the abutment rod 318 on the upper side of the passive rod 317, driving the passive rod 317 to rotate slightly. Then, the lower abutment rod 318 pushes the guide plate 33, causing the guide tube 31 to slide axially. When sliding, the linkage plate 36 is driven to rotate through the card seat 37, thereby adjusting the angle of the second nozzle 38 and changing the spray height of the first nozzle 32, which greatly improves the cleaning efficiency and cleanliness of surgical instruments. After cleaning, the isolation cover 6 is rotated by the cylinder 7 to separate it from the liquid outlet pipe 5. At this time, the cleaning liquid inside the cleaning tank 1 can be automatically discharged through the liquid outlet pipe 5.
