Detailed implementation manners

[0030] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0031] As Figure 1 shown, the micro instrument non-destructive cleaning device proposed by the present invention includes a placement area, a flushing area, a washing area, a drying and disinfection area, a maintenance area, and a recovery area. The micro instrument non-destructive cleaning device includes a guiding device 1 and an instrument fixing frame 2. The instrument fixing frame 2 can move within the guiding device 1 and sequentially pass through the flushing area, the washing area, the drying and disinfection area, and the maintenance area.

[0032] As Figure 2As shown in the figure, the guiding device 1 includes a moving track 11 and a moving plate 12 provided on the side wall of the non-destructive cleaning device for microscopic instruments. The moving plate 12 is arranged in the moving track 11 and can move back and forth driven by a motor. The instrument fixing frame 2 is detachably connected to the moving plate 12 through a snap structure, and the instrument fixing frame 2 is driven to move by means of the moving plate 12. An infrared emitting device (not shown in the figure) is provided on the moving plate 12, and infrared receiving devices are provided at specific positions in the flushing area, washing area, drying and disinfection area, maintenance area, and recovery area. Through the mutual cooperation of the infrared emitting device and the infrared receiving device, the movement process of the instrument fixing frame can be controlled, and the instrument fixing frame can be stopped at an appropriate position in the flushing area, washing area, drying and disinfection area, or maintenance area for related operations. For example Figure 3 As shown in the figure, the instrument fixing frame 2 includes a plurality of fixing units 21, and a plurality of fixing clips 211 are uniformly arranged along the border of the fixing unit 21. Any-shaped microscopic instrument can be firmly fixed within the fixing unit 21 through the fixing clips 211. Since the instrument fixing frame 2 is transparent up and down and not sealed, most surfaces of the microscopic instrument can be observed, facilitating subsequent automated processing.

[0033] The placement area is used to place the instrument fixing frame 2. During operation, the placement operation cover 7 is opened, and the instrument fixing frame 2 is detachably arranged within the guiding device 1.

[0034] The flushing area includes an upper flushing camera 31, an upper flushing device 32, a lower flushing camera 33, and a lower flushing device 34, which are used to flush the bloodstains and stains on the surface of the microscopic instrument. The upper flushing camera 31 and the lower flushing camera 33 are used to capture images of the front and back sides of the microscopic instrument. The upper flushing device 32 and the lower flushing device 34 are used to provide flushing water flows with appropriate pressures. For example Figure 4 As shown in the figure, the upper flushing device 32 includes a plurality of cleaning units 321 corresponding to the fixing units 21, and each cleaning unit 321 includes a plurality of flushing nozzles 322 arranged in an array. Figure 5 As shown in the figure, the flushing nozzle 322 includes a water spraying pipe 3221 and a micro air pump 3222, and the working state of the micro air pump 3222 can be adjusted to regulate the water outlet pressure of the flushing nozzle 322. The structure of the lower flushing device 34 is the same as that of the upper flushing device 32. During operation, based on the images captured by the upper flushing camera 31 and the lower flushing camera 33, the area where the microscopic instrument is located and the positions where there are bloodstains or stains on the microscopic instrument are judged, and the flushing nozzles corresponding to the area where the microscopic instrument is located in the upper flushing device 32 and the lower flushing device 34 are controlled to work. Moreover, the flushing nozzles corresponding to the positions of the bloodstains or stains have a higher water outlet pressure, ensuring accurate flushing while guaranteeing the flushing effect.

[0035] The washing area includes an upper coupling device 41 and a lower coupling device 42. In the non-working state, the upper coupling device 41 and the lower coupling device 42 are separated from each other. In the working state, the upper coupling device 41 and the lower coupling device 42 form a sealed connection, enclosing the instrument fixing frame 2 therein, and filling with a prepared multi-enzyme cleaning solution for washing. The multi-enzyme cleaning solution finally decomposes macromolecular organic contaminants such as proteins, fats, and sugars that are insoluble in water into water-soluble small molecule substances through the catalytic hydrolysis reaction of enzymes, and can decompose various organic substances attached to the microscopic instruments. In order to enclose the instrument fixing frame 2, the sides of the upper coupling device 41 and the lower coupling device 42 are in an inverted concave shape, and when sealed, the moving plate 12 contacts the upper coupling device 41 and the lower coupling device 42 respectively. Combining attachment Figure 1 and attachment Figure 6It can be known that the upper combining device 41 includes an upper outer shell 411 and an upper sealing shell 412. An upper sealing cavity 413 is formed between the upper outer shell 411 and the upper sealing shell 412. An upper connecting plate 415 with a ventilation hole is arranged at the port of the upper sealing cavity 413. The upper micro air pump 414 communicates with the upper sealing cavity 413 and can keep the upper sealing cavity 413 in a high-pressure state. The lower combining device 42 includes a lower outer shell 421 and a lower sealing shell 422. A lower sealing cavity 423 is formed between the lower outer shell 421 and the lower sealing shell 422. A lower connecting plate 425 with a ventilation hole is arranged at the port of the lower sealing cavity 423. The lower micro air pump 424 communicates with the lower sealing cavity 423 and can keep the lower sealing cavity 423 in a high-pressure state. Through the high-pressure sealing of the upper sealing cavity 413 and the lower sealing cavity 423, it can be ensured that at the joint position of the upper combining device 41 and the lower combining device 42, external gas and impurities will not enter, and the internal liquid will not leak out. The upper sealing cavity 413 is provided with two through holes that are not communicated with the upper sealing cavity. A washing liquid valve 416 and a clean water valve 417 are respectively arranged in the two through holes. The washing liquid valve 416 is connected to a washing liquid storage container 43 through a washing liquid delivery pipe 418. The clean water valve 417 is connected to a clean water storage container 44 through a clean water delivery pipe 419. The lower sealing cavity 423 is provided with a through hole that is not communicated with the lower sealing cavity. A discharge valve 426 is arranged in the through hole. The discharge valve 426 is connected to a sewage storage container 45 through a discharge pipe 427. In the working state, the upper combining device 41 and the lower combining device 42 are connected to each other. The upper micro air pump 414 and the lower micro air pump 424 start to work to ensure high-pressure sealing. The prepared multi-enzyme cleaning liquid enters the formed cavity through the washing liquid delivery pipe 418 and the washing liquid valve 416, so that the microscopic instruments in the instrument fixing frame 2 are immersed in the multi-enzyme cleaning liquid. After 3-5 minutes, the multi-enzyme cleaning liquid is discharged through the discharge valve 426. After the discharge is completed, the discharge valve 426 is closed. Clean water enters the formed cavity through the clean water delivery pipe 419 and the clean water valve 417, so that the microscopic instruments in the instrument fixing frame 2 are immersed in the clean water for 1 minute. The discharge valve 426 is opened to discharge the clean water. After the discharge is completed, the discharge valve 426 is closed. The clean water injection / discharge process is repeated 3-4 times to rinse the microscopic instruments in the instrument fixing frame 2 and remove the cleaning liquid on the surface. After the work is completed, the upper combining device 41 and the lower combining device 42 are separated from each other. The washing liquid delivery pipe 418, the clean water delivery pipe 419, and the discharge pipe 427 are all flexible structures and can be extended or contracted within a certain range.

[0036] The drying and disinfection area includes an upper drying and disinfection device 51 and a lower drying and disinfection device 52, which are used to dry and disinfect the washed microscopic instruments to further ensure the use safety of the microscopic instruments. As Figure 7As shown, the upper drying and disinfection device 51 includes an upper blower 511, an upper air shunt pipe 512, and an ultraviolet sterilization lamp 513 that are distributed in sequence from top to bottom. The air outlet of the upper blower 511 is connected to the upper air shunt pipe 512 through a pipeline. The lower surface of the upper air shunt pipe 512 is equipped with evenly distributed air flow nozzles. Below the air flow nozzles is a heating wire 11, and below the heating wire 11 is an ultraviolet sterilization lamp 12. The lower drying and disinfection device 52 has the same structure as the upper drying and disinfection device 51.

[0037] The maintenance area includes an upper maintenance device 61 and a lower maintenance device 62, which are used for rust removal and maintenance of microinstruments. The upper maintenance device 61 includes an upper laser 611, an upper robotic arm module 612, and an upper laser emission gun 613. The upper laser emission gun 613 is mounted on the upper robotic arm module 612, and the position of the upper laser emission gun 613 is adjusted by the upper robotic arm module 612. As Figure 8 shown, the upper laser emission gun 613 includes a housing. An emission window 6131 for emitting a light beam is opened at the front end of the housing, and an incident window (not shown in the figure) for the light beam to enter is opened at the side end of the housing. A galvanometer group is installed inside the housing, and a field lens group is configured at the emission window. A reflecting mirror group and a collimating lens group are sequentially configured on the incident window, so that the upper laser emission gun 613 is integrated with the upper laser 611 through a flexible wire harness. When the laser emits a light beam, the light beam is transmitted to the collimating lens group through the flexible wire harness. The collimating lens group collimates the light beam, and then the light beam enters the housing through the reflecting mirror group in sequence. Under the action of the galvanometer group and the field lens group, the optical system is integrated and focused to output the light beam. A camera module 6132 and a rangefinder 6133 are simultaneously arranged at the front end of the housing. The camera module 6132 is used to detect whether there are rusty and corroded areas on the surface of the microinstrument to determine the area to be processed. The rangefinder 6133 is used to detect the distance between the upper laser emission gun 613 and the microinstrument. A vacuum cleaner 6134 is arranged at the side end of the housing. The vacuum cleaner 6134 is used to collect and filter the dust generated during the laser cleaning process. The lower maintenance device 62 includes a lower laser 621, a lower robotic arm module 622, and a lower laser emission gun 623. The lower laser emission gun 623 is mounted on the lower robotic arm module 622, and the position of the lower laser emission gun 623 is adjusted by the lower robotic arm module 622. The structure of the lower laser emission gun 623 is the same as that of the upper laser emission gun 613. Through the mutual cooperation of the upper laser emission gun 613 and the lower laser emission gun 623, the rust on the surface of the microinstrument can be completely removed by laser. Moreover, by setting parameters, a dense oxide protection film or a metal melting layer can be formed on the metal surface to improve the surface strength and corrosion resistance.

[0038] The recycling area is used to recycle the instrument fixing frame 2. During operation, open the recycling operation cover 8, take out the instrument fixing frame 2 from the guiding device 1, remove the microsurgical instruments in the instrument fixing frame 2, and then pack them.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1) Driven by the guiding device, with the help of infrared positioning, the instrument fixing frame sequentially passes through the flushing area, washing area, drying and disinfection area, and maintenance area, realizing the full automation of cleaning.

[0041] 2) The washing and rinsing of microsurgical instruments are realized by the separation and combination of the upper combining device and the lower combining device, reducing the detergent used for each washing. Moreover, it can ensure that the detergent used for each washing is new, avoiding cross-infection between microsurgical instruments in different cleaning batches.

[0042] 3) The possible rust on the microsurgical instruments is removed by laser cleaning, improving the maintenance quality.

[0043] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. It should be noted that for those skilled in the art of this technology, any equivalent changes made to the present invention without departing from the design structure and principle of the present invention are regarded as the protection scope of the present invention.
