DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7 As shown, a cervical cancer detection and screening device according to an embodiment of the present invention comprises a base 1, an upper expansion shell 2 is arranged above one side of the base 1, a lower expansion shell 3 is arranged below the upper expansion shell 2, a second driving component 131 is arranged inside the base 1, a rotating rod 132 is fixed to the end of the rotating shaft of the second driving component 131, a clamping plate 4 is arranged at one end of the rotating rod 132 away from the second driving component 131, and clamping frames 42 are arranged on both sides of the clamping plate 4; When detecting and screening for cervical cancer, it is necessary to take samples from the patient's cervix. When taking samples, the upper expansion shell 2 and the lower expansion shell 3 are opened, and then the sampling cotton ball for sampling is placed on the front end of the clamping plate 4, and the cotton ball is clamped on the surface of the clamping plate 4 by the clamping frame 42. Then the staff holds the handle of the base 1 and picks up the base 1. At this time, the upper expansion shell 2 and the lower expansion shell 3 are in a closed state, and then the upper expansion shell 2 and the lower expansion shell 3 are inserted into the body of the patient to be examined, and then the upper expansion shell 2 and the lower expansion shell 3 are opened. At this time, the upper expansion shell 2 and the lower expansion shell 3 are opened to open a certain space in the patient's body. At the same time, the rotating rod 132 pushes the clamping plate 4 forward to make the clamping plate 4 It extends from the position between the upper expansion shell 2 and the lower expansion shell 3, and then the cotton ball will touch the cervix of the uterus, and the second driving component 131 is started to drive the rotating rod 132 to rotate. At this time, the rotating rod 132 drives the clamping plate 4 to rotate, and the clamping plate 4 can drive the cotton ball to wipe the cervix of the uterus. Sampling can be completed by wiping with the cotton ball, and the sampled cotton ball can be tested and analyzed to determine whether cervical cancer is present. Then the upper expansion shell 2 and the lower expansion shell 3 are closed, and at the same time, the rotating rod 132 drives the clamping plate 4 to retract to the position between the upper expansion shell 2 and the lower expansion shell 3, and then the base 1 is pulled to drive the upper expansion shell 2 and the lower expansion shell 3 to be taken out from the patient's body to complete the sampling, thereby reducing the discomfort caused to the patient by the sampling.

[0024] like Figures 1 to 5 As shown, a first movable cavity 14 is provided on one side of the interior of the base 1, and a second movable cavity 15 is provided on the other side of the interior of the base 1. A first lifting frame 21 is slidably connected to the interior of the first movable cavity 14, and one end of the first lifting frame 21 extending to the outside of the first movable cavity 14 is fixedly connected to the upper expansion shell 2. A second lifting frame 32 is slidably connected to the interior of the second movable cavity 15, and one end of the second lifting frame 32 extending to the outside of the second movable cavity 15 is fixedly connected to the lower expansion shell 3. The interior of the base 1 is rotatably connected to a drive shaft 12, and the drive shaft 12 is A first driving assembly 11 is provided at one end, and the first driving assembly 11 is installed on one side of the base 1. The end of the rotating shaft of the first driving assembly 11 is fixedly connected to one end of the driving shaft 12. First gears 121 are fixed on both sides of the outside of the driving shaft 12. A plurality of teeth are fixed at equal intervals on the inner side of the second lifting frame 32. The second lifting frame 32 is meshed with one of the first gears 121 through the teeth. A plurality of teeth are fixed at equal intervals on the outer side of the first lifting frame 21. The first lifting frame 21 is meshed with another first gear 121 through the teeth. When the upper expansion shell 2 and the lower expansion shell 3 need to be opened, the first driving assembly 11 is started to drive the driving shaft 12 to rotate. At this time, the driving shaft 12 drives the two first gears 121 to rotate, one of the first gears 121 drives the second lifting frame 32 to move downward inside the second active cavity 15, and the other first gear 121 drives the first lifting frame 21 to move upward inside the first active cavity 14. At this time, the second lifting frame 32 drives the lower expansion shell 3 to move downward, and the first lifting frame 21 drives the upper expansion shell 2 to move upward, so that the upper expansion shell 2 and the lower expansion shell 3 can expand a certain space in the patient's body, which is more convenient for subsequent sampling.

[0025] like Figures 1 to 6 As shown, a second gear 122 is fixed between the first gears 121, a telescopic shell 13 is arranged below the second gear 122, a cavity for the telescopic shell 13 to move is opened inside the base 1, the top of the telescopic shell 13 is meshed and connected with the second gear 122, and the second driving assembly 131 is installed inside the telescopic shell 13; While the driving shaft 12 drives the first gear 121 to rotate, the driving shaft 12 drives the second gear 122 to rotate. At this time, the second gear 122 drives the telescopic shell 13 to move in the cavity inside the base 1, so that the telescopic shell 13 can push the rotating rod 132 to extend forward. At this time, the clamping plate 4 can be extended from between the upper expansion shell 2 and the lower expansion shell 3 to facilitate subsequent sampling. When the upper expansion shell 2 and the lower expansion shell 3 are not fully opened, the clamping plate 4 is inside the upper expansion shell 2 and the lower expansion shell 3. When the upper expansion shell 2 and the lower expansion shell 3 are opened to a size sufficient to hold the clamping plate 4, the clamping plate 4 can be Extending from between the upper expansion shell 2 and the lower expansion shell 3, the upper expansion shell 2 and the lower expansion shell 3 can be prevented from interfering with the extension and retraction process of the clamping plate 4. When the upper expansion shell 2 and the lower expansion shell 3 are closed, the first driving component 11 will drive the driving shaft 12 to rotate in the opposite direction. At this time, the driving shaft 12 drives the second gear 122 to rotate in the opposite direction. At this time, the second gear 122 drives the telescopic shell 13 to move in the opposite direction, so that the telescopic shell 13 can drive the rotating rod 132 to pull the clamping plate 4 back to the interior of the upper expansion shell 2 and the lower expansion shell 3, so that the clamping plate 4 can be automatically extended and retracted from the interior of the upper expansion shell 2 and the lower expansion shell 3.

[0026] like Figures 1 to 8 As shown, a support shell 133 is fixed to the bottom end of the clamping plate 4 near the rotating rod 132, and one end of the rotating rod 132 near the clamping plate 4 is inserted into the inside of the support shell 133. A first spring 134 is fixed to one end of the rotating rod 132 near the clamping plate 4, and the other end of the first spring 134 is fixedly connected to the inner side of the support shell 133; Due to the different shapes of the patients' cervix, the distance at which the clamping plate 4 can contact the cervix is ​​also different. Therefore, a first spring 134 is provided. When the cotton ball contacts the patient's cervix, it pushes the clamping plate 4. At this time, the clamping plate 4 pushes the supporting shell 133. The inner wall of the supporting shell 133 and the rotating rod 132 squeeze the first spring 134. The first spring 134 can be adaptively compressed to facilitate the clamping plate 4 to push the cotton ball to contact the cervix. The connection position between the clamping plate 4 and one end of the rotating rod 132 is in an eccentric position, so that the clamping plate 4 can drive the sampling cotton ball to wipe around the cervix, so that sampling can be performed over a larger area.

[0027] like Figures 1 to 7 As shown, guide holes 41 are provided on both sides of the clamping plate 4, and the clamping frame 42 is slidably connected to the inside of the guide hole 41. A slider 421 is fixed to the side of the clamping frame 42 close to the support shell 133, and a slide bar 43 runs through the inside of the slider 421. Both ends of the slide bar 43 are fixedly connected to the clamping plate 4 through a support block. A second spring 431 is fixed to the side of the slider 421 away from the support shell 133, and the other end of the second spring 431 is fixedly connected to the support block of the slide bar 43. The second spring 431 is sleeved on the outside of the slide bar 43. When the clamping frames 42 clamp the cotton balls, the two clamping frames 42 are pulled to both sides, and the slide bar 43 guides the slider 421. The slider 421 squeezes the second spring 431, and then the cotton balls are placed between the clamping frames 42. The clamping frames 42 are then released, and the elastic force of the second spring 431 pushes the slider 421, and the slider 421 drives the clamping frames 42 to clamp the cotton balls.

[0028] like Figure 1 to Figure 2 As shown, a notch 31 is formed at the top of the lower expansion shell 3 near the clamping plate 4, and a notch 31 is also formed at the bottom of the upper expansion shell 2 near the clamping plate 4; When the rotating rod 132 pushes the clamping plate 4 to extend out from the interior of the upper expansion shell 2 and the lower expansion shell 3, the notch 31 facilitates the movement of the clamping plate 4 and prevents the clamping plate 4 from being interfered by the ends of the upper expansion shell 2 and the lower expansion shell 3.

[0029] like Figures 1 to 10As shown, a support plate 444 is fixed to the top of the support shell 133, and a push rod 44 is passed through the interior of the support plate 444. A baffle 443 is fixed to the end of the push rod 44 close to the rotating rod 132, and a push plate 441 is fixed to the end of the push rod 44 away from the baffle 443. The top and bottom ends of the push plate 441 are both rotatably connected with a connecting rod 442, and the end of the connecting rod 442 away from the push plate 441 is rotatably connected to the two sliders 421 respectively. A storage box 33 is arranged below the clamping plate 4, and the bottom end of the storage box 33 is fixedly connected to the lower expansion shell 3. A support rod 35 is arranged on the side of the storage box 33 away from the clamping plate 4, and the bottom end of the support rod 35 is fixedly connected to the lower expansion shell 3, and the support rod 35 is arranged on the side of the baffle 443 away from the push rod 44. When the clamping plate 4 drives the cotton ball to rotate one circle about the cervix of the uterus, the sampling work can be completed. At this time, the rotating rod 132 pulls the clamping plate 4 into the upper expansion shell 2 and the lower expansion shell 3, and the second driving component 131 drives the rotating rod 132 to rotate, and the rotating rod 132 drives the clamping plate 4 to rotate, so that the eccentric part of the clamping plate 4 faces the lower expansion shell 3, and then the rotating rod 132 pulls the clamping plate 4 into the upper expansion shell 2 and the lower expansion shell 3, and then the baffle 443 is pushed by the support rod 35, and the baffle 44 The push rod 44 drives the push plate 441, and the push plate 441 drives the slider 421 through the two connecting rods 442, and the slider 421 drives the clamping frame 42 to move to both sides. At this time, the cotton balls on the surface of the clamping plate 4 will fall off, and the storage box 33 can receive and store the fallen cotton balls, and the cotton balls can be conveniently removed from the front end of the clamping plate 4. In this process, the cotton balls after sampling can be stored in the storage box 33, reducing the contact between the sampled cotton balls and the outside air, preventing the cotton balls from being polluted by the outside air and affecting the subsequent detection results.

[0030] like Figures 1 to 10 As shown, a rotating groove 331 is fixed on one side of the top of the storage box 33, a sealing cover 34 is provided on the top of the storage box 33, a connecting block 341 is fixed on one side of the top of the sealing cover 34, a rotating shaft 342 is fixed on one side of the bottom of the sealing cover 34, the rotating shaft 342 is rotatably connected to the inside of the rotating groove 331, a pull rope 351 is passed through the inside of the support rod 35, one end of the pull rope 351 is fixedly connected to the connecting block 341, a telescopic rod 353 is passed through the top of the support rod 35, one end of the telescopic rod 353 away from the storage box 33 is fixedly connected to the other end of the pull rope 351, and a guide wheel 352 is fixed on the side of the support rod 35 away from the storage box 33; When the baffle 443 moves to the telescopic rod 353, the baffle 443 pushes the telescopic rod 353 to pull the drawstring 351, and the guide wheel 352 guides the drawstring 351. The drawstring 351 pulls the connecting block 341 to make the sealing cover 34 rotate at the top of the rotating groove 331 through the rotating shaft 342. At this time, the sealing cover 34 can be opened. After opening, the telescopic rod 353 is fixed. At this time, the telescopic rod 353 pushes the baffle 443 in the opposite direction, so that the cotton balls at the front end of the clamping plate 4 can fall off, and the sealing cover 34 can be automatically opened and the cotton balls can be automatically fallen off. At this time, the cotton balls are sealed in the storage box 33 by the sealing cover 34, so that the cotton balls can be kept isolated from the outside world before the upper expansion shell 2 and the lower expansion shell 3 are taken out of the patient's body, so as to prevent the outside air from contaminating the sampling cotton balls during the process of the upper expansion shell 2 and the lower expansion shell 3.

[0031] like Figures 9 and 10 As shown, a coil spring 343 is fixed to the outside of the rotating shaft 342, and the outer side of the coil spring 343 is fixedly connected to the rotating groove 331; When the sealing cover 34 is unscrewed at the top of the rotating groove 331 through the rotating shaft 342, the rotating shaft 342 drives the coil spring 343 to tighten, and the telescopic rod 353 loses support after the storage box 33 stores the cotton balls. At this time, the coil spring 343 drives the rotating shaft 342 to rotate in the opposite direction, and the rotating shaft 342 drives the sealing cover 34 to reset. At the same time, the connecting block 341 pulls the pull rope 351, and the pull rope 351 pulls the telescopic rod 353 to reset, so that the top of the storage box 33 can be automatically sealed through the sealing cover 34, reducing the contact between the cotton balls inside the storage box 33 and the air.

[0032] like Figure 7 and Fig. 9 As shown, a push frame 354 is fixed to one end of the telescopic rod 353 close to the storage box 33, and a groove is provided in the middle of the top of the push frame 354, and the inner diameter of the groove is larger than the outer diameter of the rotating rod 132; When the baffle 443 pushes the telescopic rod 353, it will come into contact with the push frame 354. When the baffle 443 moves to the inside of the upper expansion shell 2 and the lower expansion shell 3, the distance between the telescopic rod 353 and the rotating rod 132 is gradually shortened. The push frame 354 can extend the contact area between the telescopic rod 353 and the baffle 443, making it easier for the baffle 443 to push the telescopic rod 353 to move.
