[0021] like Figure 1-2 As shown:

[0022] In the initial state, the three duckbill plates 1 are in a gathered state, and the three duckbill plates 1 are respectively connected to the annular frame 3 through the sleeve rods 11, and the three sleeve rods 11 play a guiding role for the duckbill plates 1; before the device is used, the three duckbill plates 1 are preheated to avoid discomfort to the patient's body; the frame is installed at a designated position on the bed body, so that the left ends of the three duckbill plates 1 are aligned with the patient's cervix, and the frame drives the three duckbill plates 1 to move close to the cervix through the annular frame 3, and the three duckbill plates 1 are inserted into the patient's cervix at the same time, and the three sleeve rods 11 can simultaneously drive the three duckbill plates 1 to slide away from each other, thereby expanding the cervix, which is convenient for subsequent curettage and sampling of the affected part of the cervix;

[0023] Since the three duckbill plates 1 are all pressed against the inner wall of the cervix through the expansion force, the polyps on the affected part of the inner wall of the cervix are embedded into multiple sampling ports under the action of the expansion force. The doctor observes the polyps embedded in the sampling ports through the image collector. Since the polyps on the cervical wall are embedded in the sampling ports, the polyps in the sampling ports appear as a convex arc shape, and the polyps are naturally in a slightly magnified state, which makes it easier for the image collector to observe the enlarged polyps in the affected part in detail. Then the sampling part is controlled to cut and sample the polyps in the multiple sampling ports at the same time, so that samples from multiple parts can be taken at one time. The cut samples are collected in the sampling part in sequence. After the duckbill plate 1 is taken out, the sampling part is removed, and after taking out multiple samples, the samples are pathologically analyzed. The multiple samples taken at the same time are convenient for comparative analysis.

[0024] like Figure 2-6 As shown:

[0025] The fixing seat 12 is fixedly connected to the inner wall of the duckbill plate 1, and a trapezoidal slide groove is provided on the fixing seat 12. A trapezoidal rod is fixedly connected to the outer end of the collecting seat 2, and the collecting seat 2 is slidably connected to the trapezoidal slide groove on the fixing seat 12 through the trapezoidal rod. The fixing seat 12 is threaded with screws for tightly pressing on the collecting seat 2 to fix the collecting seat 2. The collecting seat 2 corresponds to the sampling port, and the cutting part is controlled to rotate 180 degrees to cut the polyp sample in the sampling port, and the sample is collected in the cavity 23. At the same time, a closed space is formed between the cutting part after rotating 180 degrees and the cavity 23 to prevent the sample from falling into the uterus when the collecting seat 2 is taken out. At the same time, the closed space protects the sample to prevent infection during the sample transfer process.

[0026] like Figure 3-6 As shown:

[0027] The image collector on the scraper 22 can observe and monitor the polyps before the scraper 22 rotates to take samples. The rotating shaft 21 drives the multiple scrapers 22 to rotate 180 degrees around the axis of the rotating shaft 21. While the multiple scrapers 22 rotate, the blades thereon respectively cut the polyps in the multiple sampling ports and cut the polyps. The multiple polyp samples cut off fall into the corresponding cavities 23 in turn for collection and storage. At the same time, the scraper 22 after rotating 180 degrees is set upward to cover the upper end of the cavity 23, so that a closed space is formed between the scraper 22 and the duckbill plate 1 for storing and protecting the samples. The rotating locking nail 24 is tightly pressed against the collection seat 2 to fix the positions of the multiple scrapers 22 and maintain a closed storage space.

[0028] like Figure 4 As shown:

[0029] The cutting part also includes a fixing nail 25. A plurality of scrapers 22 are evenly slidably connected to the rotating shaft 21 along the axis direction of the rotating shaft 21. Each scraper 22 is threadedly connected with a fixing nail 25. The fixing nail 25 is screwed tightly against the rotating shaft 21 to fix the scraper 22 to the rotating shaft 21, so that when the rotating shaft 21 rotates, the scraper 22 can be driven to rotate synchronously.

[0030] The connection between a certain scraper 22 and the rotating shaft 21 can be selectively controlled to make them rotate synchronously, so that the scraper 22 connected to the rotating shaft 21 can cut and sample the polyp, and the scraper 22 not connected to the rotating shaft 21 is stored in the corresponding cavity 23 under the action of its own gravity when the rotating shaft 21 rotates, so that the sample of the part will not be cut and sampled, so that the designated part can be sampled, different parts can be sampled selectively, or different numbers of samples can be cut according to needs.

[0031] like Figure 7-8 As shown:

[0032] The gynecological and obstetric curettage device also includes a trapezoidal rail 31, a ring frame 4, a sleeve block 41, an extension plate 42 and an insertion rod 43. The ring frame 4 is evenly surrounded and fixedly connected with three sleeve blocks 41. The three sleeve rods 11 are respectively connected with the three sleeve blocks 41. The extension plate 42 is fixedly connected to one of the sleeve blocks 41. The lower end of the extension plate 42 is slidably connected to the trapezoidal rail 31. The trapezoidal rail 31 is fixedly connected to the ring frame 3. When the extension plate 42 slides on the trapezoidal rail 31, it can synchronously drive the three sleeve blocks 41 to rotate. The three sleeve blocks 41 respectively drive the three duckbill plates 1 to rotate around the axis of the ring frame 3, thereby simultaneously changing the angles of the three duckbill plates 1. When the angles of the three duckbill plates 1 change, the parts in contact with the inner wall of the cervix change, thereby being able to sample different affected parts of the inner wall of the cervix.

[0033] There are multiple triangular sockets evenly distributed around the trapezoidal rail 31, the insertion rod 43 is slidably connected to the extension plate 42, and a plug is fixedly connected to the end of the insertion rod 43 close to the rotating shaft 21. The plug on the insertion rod 43 is inserted into one of the sockets, and the threaded screws on the extension plate 42 are tightly pressed against the insertion rod 43 to fix the insertion rod 43, thereby locking the angles through which the three duckbill plates 1 have been rotated.

[0034] like Figure 8-9 As shown:

[0035] The gynecological and obstetric curettage device also includes a screw 44, a bevel gear 45, a bevel gear ring 46 and a sliding sleeve 47. The three sleeve blocks 41 are respectively rotatably connected to a screw 44, and the inner ends of the three screws 44 are respectively fixedly connected to a bevel gear 45. The three bevel gears 45 are all meshed and transmission-connected with the bevel gear ring 46. The bevel gear ring 46 is evenly surrounded and fixedly connected to three sliding sleeves 47. The three sliding sleeves 47 are simultaneously slidably connected to the ring frame 4. When the sliding sleeve 47 slides on the ring frame 4, it drives the bevel gear ring 46 to rotate. The bevel gear ring 46 also drives the three bevel gears 45 to rotate, and then drives the three sleeve rods 11 to gather or disperse each other through the screw 44, thereby driving the three duckbill plates 1 to expand or close the cervix and take it out from the cervix;

[0036] The threaded connecting screws on the sliding sleeve 47 are tightly pressed against the ring frame 4 to fix the bevel gear ring 46; the sliding sleeve 47 and the sleeve block 41 are arranged alternately.

[0037] like Fig.10 As shown:

[0038] The gynecological and obstetric curettage device also includes a grab plate 13, a slot rod 14, a lever 15, a straight rod 16 and a long screw 17. The left end of the duckbill plate 1 is hingedly connected to the grab plate 13. The position of the inner wall of the grab plate 13 near the duckbill plate 1 is fixedly connected to the slot rod 14. The lever 15 slides with the slot rod 14. The lever 15 is fixed to one end of the straight rod 16. The other end of the straight rod 16 is slidably connected to the right end of the duckbill plate 1. The right end of the straight rod 16 is threadedly connected to the long screw 17, and the long screw 17 is rotatably connected to the duckbill plate 1.

[0039] Rotating the long screw 17 drives the straight rod 16 and the lever 15 to slide to the right, and the lever 15 slides in the slot rod 14 and drives the grabbing plate 13 to rotate inward around the axis of the hinge with the duckbill plate 1. When the three grabbing plates 13 gather together at the same time, the grabbing action is realized, so that the embryo or foreign body in the uterine cavity can be grabbed and removed.

[0040] like Figure 2 As shown:

[0041] The gynecological and obstetric curettage device further includes a core rod 111, which is fixedly connected to the right end of the duckbill plate 1, and the core rod 111 is slidably connected to the sleeve rod 11, and the sleeve rod 11 and the core rod 111 are fixed by screws;

[0042] Since the three duckbill plates 1 are driven to retract or expand simultaneously by the three screws 44, the virtual axis formed by the three duckbill plates 1 is always in a centered position relative to the annular frame 3, and by changing the position of the core rod 111 on the sleeve rod 11, the position of each duckbill plate 1 can be adjusted individually, so that the virtual axis formed by the three duckbill plates 1 can be in an eccentric position relative to the axis of the annular frame 3, so that foreign objects in different parts of the uterine cavity can be grasped; when grasping, the three duckbill plates 1 can be first expanded, and then the three duckbill plates 1 can be rotated at the same time, so that one of the duckbill plates 1 lifts the foreign object from the lower end, and then the other two duckbill plates 1 are adjusted to move closer to the duckbill plate 1 lifting the foreign object to clamp the foreign object. In this way, all foreign objects in the uterine cavity can be removed at one time, avoiding incomplete cleaning and repeated entry into the uterine cavity to cause damage and hidden dangers to the uterine cavity.

[0043] Furthermore: the end surface of the grabbing plate 13 away from the duckbill plate 1 is set to an arc-shaped cone tip shape to avoid getting caught on the inner wall of the cervix.

[0044] like Fig.11 As shown:

[0045] The gynecological and obstetric curettage device also includes a clamping seat 5, a screw rod 51 and a driving plate 52. The lower end of the annular frame 3 is fixedly connected to the driving plate 52, and the driving plate 52 is laterally slidably connected to the upper end of the clamping seat 5. The screw rod 51 is rotatably connected to the clamping seat 5, and the screw rod 51 is threadedly connected to the driving plate 52. The holder 5 is clamped on the bed and fixed to the bed by inserting screws. The screw rod 51 is rotated to drive the driving plate 52 and the annular frame 3 to move to the left, thereby driving the three duckbill plates 1 to be inserted into the cervix.
