It is worth mentioning that the arc shape of the arc plate 7 is a major arc, the specific structure can be shown in fig. 3, by arranging the annular groove 501 and the arc plate 7, and because the arc plate 7 is fixedly arranged on the driving platform 4 by the connecting rod 8, the rotating platform 5 can not drive the arc plate 7 to rotate after rotating, air can only be sucked from the suction holes 5011 in the gap area of the arc plate 7, so that the air suction area can be more concentrated in the area close to the pathological change skin, the suction force is more concentrated and stronger, the generated pathological change fragments can be thoroughly sucked into the filter cylinder 13, and meanwhile, the blockage of the filter cylinder 13 caused by sucking sundries from other areas can be prevented.
The driving device comprises a spring 17 fixedly connected to the bottom in the accommodating groove 503, one end of the spring 17 close to the scraping blade 16 is fixedly connected with the scraping blade 16, the bottom in the accommodating groove 503 is provided with an air guide groove 502, the side wall of the driving platform 4 is provided with a separation groove 12, an exhaust mechanism for exhausting air to the air guide groove 502 is installed in the separation groove 12, the exhaust mechanism comprises a filter cartridge 13 fixedly connected to the top in the separation groove 12, specifically, the filter cartridge 13 is a cylinder body with a filter screen embedded inside and can intercept skin scraps in air flow, the filter cartridge 13 is communicated with the driving groove 401 through an exhaust pipe 18, the filter cartridge 13 is provided with an air guide pipe 14 and an air outlet pipe 15 communicated with the inside, a pulse valve is installed in the air outlet pipe 15, the pipe diameter of the air outlet pipe 15 is larger than that of the air guide pipe 14, it should be noted that, even if part of the air flow enters the air guide pipe 14, the air flow is a very small part, and the small part of the air flow enters the lower air guide groove 502 after flowing into the air guide tube 14, but is blocked by the elastic force of the spring 17, so that the scraper 16 cannot be pushed to move, the air flow cannot enter the air guide tube 14, and therefore, when the pulse valve is opened, the air flow can only be discharged along the air outlet tube 15.
The air outlet end of the air duct 14 is arranged on the end surface of the driving platform 4 close to the rotating platform 5, the side wall of the driving platform 4 is provided with an L-shaped hole 402, the air inlet end of the L-shaped hole 402 is arranged on the end surface of the driving platform 4 close to the rotating platform 5, it should be noted that, referring to fig. 2 and 5, the end surface of the driving platform 4 is provided with a groove, the rotating platform 5 is hermetically rotated in the groove, and the end surface of the rotating platform 5 is tightly attached to the inner wall of the groove, so that only when the air guide groove 502 is communicated with the L-shaped hole 402 or the air duct 14, air can flow between the air guide groove 502 and the L-shaped hole 402 or the air duct 14.
The side wall of the driving platform 4 is provided with a backflow chamber 10, the inner wall of the backflow chamber 10 is provided with a negative pressure groove 9, the backflow chamber 10 is communicated with the driving groove 401 through an air hole 11, and the circumferential side wall of the rotating platform 5 is provided with a plurality of adsorption holes 5011.
When the device is used, the lesion part of a patient can be lifted above the base 1, and the heights of the driving table 4 and the rotating table 5 are adjusted by adjusting the telescopic component 3, so that the distance between the rotating table 5 and the lesion skin area is 1-2 mm. At this time, the centrifugal fan 6 is started, and the centrifugal fan 6 can rotate at a high speed and synchronously drive the rotating platform 5 to rotate.
After the centrifugal fan 6 is started, air can be sucked into the annular groove 501 along the adsorption hole 5011, and flows through the negative pressure tank 9, the reflux chamber 10 and the air hole 11, and finally enters the driving tank 401. After that, the air is discharged into the filter cartridge 13 along the exhaust pipe 18, when the air flow is discharged from the filter cartridge 13, if the pulse valve in the air outlet pipe 15 is opened, the air flow is discharged along the air outlet pipe 15, and when the pulse valve in the air outlet pipe 15 is closed, the air flow can only enter the air guide groove 502 below through the air guide pipe 14 and enter the accommodating groove 503 to push the scraping blade 16 to move outwards, so that the scraping blade 16 is pushed out, at the moment, the skin with pathological changes can be cleaned, and along with the intermittent opening and closing of the pulse valve, the air can be periodically discharged along the air outlet pipe 15 and the air guide pipe 14 in sequence, so that the scraping blade 16 at the lowest position can be pushed out every time.
When the pushed-out blade 16 rotates to the upper side, the air guide groove 502 at the blade 16 communicates with the L-shaped hole 402, and at this time, the spring 17 can pull back the blade 16 and discharge air along the L-shaped hole 402. In summary, during the rotation of the rotary table 5, the scraping blades 16 extend out when reaching the lowest position and retract when reaching the highest position, so that on one hand, the affected skin below can be cleaned conveniently, and on the other hand, the scraping blades 16 can be prevented from being exposed for a long time to cause accidental injury to the operator. When the clearance, only need promote drive platform 4 for revolving stage 5 moves certain distance along linear slide rail 2 round trip movement, can scrape the epidermis to the pathological change skin in the certain region of below clearly, and the clearance area is controllable, and efficiency is higher simultaneously.
In addition, it should be mentioned that, because the scraping blade 16 is extended gradually, that is, the height of the scraping blade 16 is increased gradually, the scraping blade 16 can clean the affected skin from shallow to deep, so as to avoid causing secondary injury to the patient.
Furthermore, when the scraping blade 16 scrapes the diseased skin, a large amount of diseased epidermis fragments are generated, and when the centrifugal fan 6 works, a large negative pressure is generated at the adsorption hole 5011, so that the generated diseased epidermis fragments can be sucked in and enter the filter cylinder 13 along the negative pressure groove 9, the reflux chamber 10, the air hole 11 and the exhaust pipe 18 along with the air flow, and after being intercepted by the filter screen in the filter cylinder 13, the clean air is discharged along the air guide pipe 14 or the air outlet pipe 15, so that the occurrence of the conditions that the generated diseased epidermis fragments splash to cause infection and the like can be avoided when the diseased skin is scraped.
After the use is stopped, the centrifugal fan 6 is closed, the centrifugal fan 6 and the rotating platform 5 slowly stop rotating under the inertia effect, at the moment, the rotating speed of the centrifugal fan 6 is very slow, so negative pressure cannot be continuously generated to enable air to flow, the scraping blades 16 on each position on the rotating platform 5 sequentially and slowly pass through the L-shaped holes 402, the scraping blades 16 can be pulled back by the springs 17 at each position, air in the accommodating groove 503 is discharged along the L-shaped holes 402, and therefore the scraping blades 16 can be retracted into the accommodating groove 503 after the use is stopped, and the scraping blades 16 are prevented from being exposed to hurt people or being damaged.
