Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0047] Example:

[0048] like Figure 1 , 2 As shown in Figures 4 and 6, the present invention provides a gun-shaped instrument intraoperative cleaning device, comprising a housing 101, a cover 102 is provided on the housing 101, a cleaning port 103 is provided on the cover 102, a drain port 107 is provided at the bottom of the housing 101, and a detachable filter 108 is provided at the bottom of the housing 101 above the drain port 107. A driving motor 301 is fixedly provided in the housing 101, and is fixedly provided in the housing 101. A mounting seat 302 is provided on the output shaft of the driving motor 301, and a mounting plate 304 is slidably provided at one end of the mounting seat 302, and an elastic member 307 is provided between the mounting seat 302 and the mounting plate 304. A cleaning cylinder 401 is rotatably provided on the mounting plate 304, and the cleaning cylinder 401 is eccentrically arranged with the cleaning port 103, and the middle section of the cleaning cylinder 401 is an inverted conical surface, and an annular brush 402 is provided in the cleaning cylinder 401, and a spray gun 105 facing the inverted conical surface is provided on the cover 102. A plurality of nozzles 106 are disposed at the bottom of the cover body 102 , and a water inlet 104 is disposed on the cover body 102 . The water inlet 104 is connected to the spray gun 105 and the plurality of nozzles 106 , and the water inlet 104 is connected to an external water supply system.

[0049] When in use, the use end of the gun-shaped instrument is inserted into the cleaning port 103 and contacts the annular brush 402 inside the cleaning tube 401, and the instrument is pushed downward so that the cleaning tube 401 moves toward the center of the cleaning port 103 under the action of the inverted conical surface to compress the elastic member 307, and the driving motor 301 drives the mounting seat 302 to rotate. During the rotation process, the mounting seat 302 can drive the cleaning tube 401 to move in an annular direction through the mounting plate 304, so that the end of the instrument can contact the annular brush 402 to comprehensively clean the instrument. During the cleaning process, water is supplied to the spray gun 105 and the nozzle 106 through an external water supply system. The spray gun 105 sprays water onto the inverted conical surface of the cleaning tube 401 to rinse the instrument, and the nozzle 106 sprays water into the inside of the cleaning tube 401 to clean the cleaning tube 401. During the cleaning process, waste water can be discharged through the drain port 107. The filter net 108 is used to receive impurities or medical components to prevent impurities from clogging the drain port 107 and prevent parts on the instrument from falling into the drain port 107.

[0050] like Figure 3 , 5As shown in FIG. 6 , in this embodiment, a driving mechanism connected to the cleaning cylinder 401 is disposed in the housing 101, and the driving mechanism converts the rotation of the output shaft of the driving motor 301 into the self-rotation of the driving cleaning cylinder 401 when the mounting plate 304 slides an arbitrary distance. The driving mechanism includes a driving gear 404 disposed at the bottom of the cleaning cylinder 401, and the gear ring 203 is disposed in the housing 101 so as to be movably disposed in the plane thereof through the mounting assembly, and the driving gear 404 is meshed with the gear ring 203.

[0051] In the process of driving the mounting seat 302 to rotate by the driving motor 301, the mounting seat 302 drives the mounting plate 304 to swing in a circular direction, so that the cleaning cylinder 401 revolves in the shell 101. During the revolution, the cleaning cylinder 401 can be driven to rotate by itself through the engagement between the driving gear 404 and the gear ring 203, so that the end side of the gun-shaped instrument is comprehensively cleaned by the moving annular brush 402, effectively reducing the cleaning blind spots.

[0052] like Figure 1 , 5 As shown in Figure 6, in this embodiment, the mounting assembly includes at least two groups of mounting columns 205, the axes of the two groups of mounting columns 205 are perpendicular to each other and are arranged on the peripheral side of the gear ring 203.

The bottom of the mounting plate 304 is provided with a connecting assembly connected to the gear ring 203, and the gear ring 203 is driven to translate following the mounting plate 304 through the connecting assembly. The connecting assembly includes a connecting ring 204 arranged on the gear ring 203 and arranged concentrically therewith, and the bottom of the mounting plate 304 is provided with an arc frame 308, which is slidably clamped on the connecting ring 204.

[0053] In the process of pushing the cleaning cylinder 401 to move along the center of the circle toward the cleaning port 103 by the end of the instrument, the mounting plate 304 is driven to slide on the end of the mounting seat 302. During the sliding process, the mounting plate 304 drives the gear ring 203 to follow the movement of the driving gear 404 through the arc frame 308, and guides the guide block 202 through the slide rail 201, and guides the mounting column 205 through the guide block 202, so that the gear ring 203 can only translate in its plane but cannot rotate, so that the cleaning cylinder 401 is driven to rotate during the revolution through the relative movement of the driving gear 404 and the gear ring 203, so as to quickly brush the end of the instrument. During the brushing process, the elastic member 307 is compressed by the movement of the mounting plate 304, and the elastic member 307 applies elastic force to the cleaning cylinder 401, so that the brushing force can be adjusted by controlling the distance that the instrument extends downward.

[0055] like Figure 1 , 2 As shown in Figures 7 and 8, in the present embodiment, a brush column 403 is fixedly provided on the cleaning cylinder 401, a mounting frame 501 is hingedly connected to the brush column 403, a scraper 505 is provided at the bottom of the mounting frame 501, the scraper 505 contacts the inner side surface of the annular brush 402, scraper teeth are provided on the scraper 505, the scraper 505 is connected to the mounting seat 302 through a limiting assembly, and the scraper 505 is driven by the limiting assembly to always move to the side away from the cleaning port 103. The limiting assembly includes an extension rod 303 arranged on the mounting seat 302, a guide seat 305 is arranged on the mounting plate 304, the guide seat 305 is slidably arranged on the extension rod 303, one end of the extension rod 303 is fixedly connected to a connecting frame 504, one end of the connecting frame 504 is provided with an arc-shaped slider 503, an annular track 109 is arranged at the bottom of the cover body 102, the arc-shaped slider 503 is slidably clamped in the annular track 109, a limiting ridge 502 is arranged on the mounting frame 501, and the limiting ridge 502 is slidably clamped at the bottom of the arc-shaped slider 503.

[0056] Tools such as gun-shaped forceps, clamps, and pliers can also be rubbed on the brush column 403 to clean the inner dead corner. During the cleaning process, the sliding of the mounting plate 304 is positioned by the cooperation of the guide seat 305 and the extension rod 303, so that the mounting plate 304 can stably follow the rotation of the mounting seat 302, and the elastic member 307 can be compressed. During the rotation of the mounting seat 302, the arc-shaped slider 503 is driven to slide in the annular track 109 through the connecting frame 504, and then the scraper 505 follows the movement of the cleaning cylinder 401 in the housing 101 through the cooperation of the arc-shaped slider 503 and the limiting convex ridge 502. During the self-rotation process, the cleaning cylinder 401 scrapes off the impurities attached to the annular brush 402 through contact with the scraper 505 and removes the impurities under the action of the nozzle 106, so as to prevent the impurities from being attached to the annular brush 402 for a long time, and further improve the cleaning effect.

[0057] Specific usage and beneficial effects of the present invention:

[0058] The device can be used for temporary cleaning during surgery. When in use, the end of the gun-like instrument to be cleaned is inserted into the cleaning port 103 and contacts the annular brush 402 on the inner inverted conical surface of the cleaning cylinder 401. The cleaning liquid is sprayed out by the spray gun 105 to clean the end of the gun-like instrument. The end of the gun-like instrument can cooperate with the inverted conical surface of the cleaning cylinder 401 to push the cleaning cylinder 401 so that the cleaning cylinder 401 is close to the center of the cleaning port 103, and the mounting plate 304 is driven to slide on one end of the mounting seat 302 to compress the elastic member 307. The mounting seat 302 is driven to rotate by the driving motor 301 so that the cleaning cylinder 401 revolves in the shell 101 along the output shaft of the driving motor 301, and the driving mechanism is used to drive the driving motor 301 to rotate. The rotation of the output shaft of the motor 301 is converted into driving the cleaning cylinder 401 to rotate, so that the annular brush 402 on the inside of the cleaning cylinder 401 moves and contacts each surface of the gun-shaped instrument in turn to comprehensively clean the cleaning end of the gun-shaped instrument. At the same time, even if the mounting plate 304 slides, the cleaning cylinder 401 can be continuously driven to rotate. The user can push the inverted conical surface of the cleaning cylinder 401 downward to move different distances according to the instruments of different materials. Under the action of the elastic member 307, the annular brush exerts different pressures on the instruments, thereby autonomously controlling the brushing force, effectively avoiding wear and damage to the ends of instruments made of fragile materials due to uncontrollable brushing force during the cleaning process, thereby improving the practical value of the cleaning device.
