Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an integrated auxiliary device for postpartum uterine cavity examination and treatment. Background Art

[0002] In obstetrics and gynecology clinical practice, postpartum recovery is crucial for women, and the health of the uterine cavity directly impacts the mother's overall recovery and subsequent fertility. The delivery process can cause numerous changes to the uterine cavity, such as cervical lacerations, residual placental membranes, lochia, and other debris. These can not only easily lead to postpartum complications such as infection and bleeding, but can also pose a risk for long-term gynecological diseases. With the increasing number of older mothers, postpartum uterine cavity problems are becoming increasingly complex and diverse, creating an increasingly urgent need for accurate and efficient examinations and treatments.

[0003] The invention patent with publication number CN 116920249 A discloses an intrauterine adhesion prevention airbag. It includes an intrauterine airbag, which, when inflated, expands to open the uterine cavity. The bottom of the intrauterine airbag is connected to an airbag inflation tube, the upper end of which is connected to the airbag inlet and outlet ports, and the airbag inflation tube is capable of inflating the intrauterine airbag. The top of the intrauterine airbag is provided with multiple flushing ports, the bottom of the intrauterine airbag is connected to a flushing tube, the upper end of which extends into the airbag inflation tube and is connected to the multiple flushing ports. The intrauterine airbag of the present invention uses air as a medium to expand the uterine cavity, preventing adhesions caused by the wound surfaces of the anterior and posterior uterine walls. Since the air is evenly dispersed in the airbag, the pressure of the airbag wall on the uterine cavity is consistent, preventing uterine prolapse. At the same time, the flushing structure provided can be used to flush or administer medication to the uterine cavity, improving the healing effect of the intrauterine cavity.

[0004] However, the flushing tube in this application cannot flush the uterine cavity when the uterine cavity is stretched, nor can it flush the interior of the uterine cavity in all directions, resulting in poor flushing effect. Summary of the Invention

[0005] In response to the above-mentioned problems, the present invention aims to provide an integrated auxiliary device for postpartum uterine cavity examination and treatment, which can flush the uterine cavity while expanding it, and can also perform all-round flushing of the interior of the uterine cavity, thereby achieving a better flushing effect.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: The integrated auxiliary device for postpartum uterine cavity examination and treatment comprises a shell and an airbag arranged at the top of the shell, wherein the shell is provided with: An inflatable structure, disposed inside the shell, for inflating the airbag; The expansion structure is arranged inside the shell and below the airbag, and is used to expand the uterine cavity and expand the visible range inside the cavity; The rotating flushing structure is arranged inside the shell, located between the expansion structures, and connected to the expansion structures, and is used for all-round flushing of the inside of the uterine cavity.

[0007] Furthermore, the inflatable structure includes: The piston component is clamped inside the shell and located below the expansion structure; The inflation tube is located inside the shell, one end of which is connected to the inside of the airbag and the other end is connected to the piston component.

[0008] Furthermore, the piston component includes: A baffle is located on one side of the support structure and is sleeved in the side wall of the shell; a piston, located below the baffle; a fixed plate, located below the piston; The driving member is located below the fixed plate and is connected to the piston.

[0009] Furthermore, the support structure includes: A driving component is arranged inside the housing; The connecting rod component is located inside the housing and is connected to the driving component.

[0010] Furthermore, the driving component includes: A support seat, located below the connecting rod component; The electric telescopic rod is located above the support seat and is connected to the connecting rod component.

[0011] Furthermore, the connecting rod component includes: A fixing rod is located above the supporting base; A plurality of movable rods are located above the support base and are respectively connected to the fixed rods; A plurality of movable components are located between a fixed rod and an adjacent movable rod or between two adjacent movable rods, and each movable component is connected to the fixed rod or the movable rod.

[0012] Furthermore, each mobile component includes: A plurality of sleeves are sleeved on the fixed rod and the movable rod; The cross connecting rod is located between the fixed rod and the multiple movable rods and is movably connected to the sleeve.

[0013] Furthermore, the rotary flushing structure includes: a rotating member positioned between the connecting rod members and connected to one of the plurality of sleeves; A flushing component is located between the rotating components and is connected to the rotating components; The discharge component is arranged inside the shell and below the flushing component.

[0014] Furthermore, the rotating component includes: a moving ring connected to one of the plurality of sleeves; The spiral column is connected to the support base and is located in the middle of the moving ring.

[0015] Furthermore, the flushing component includes: A connecting pipe is provided in the shell and is connected to an external water pipe; The flushing pipe is located on the outside of the spiral column and is movably connected to the connecting pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Through the mutual cooperation of the airbag, the driving member, the piston, the fixing plate and the shell, one end shell of the airbag is extended into the patient's uterine cavity, and then the driving member is started to drive the piston to move downward, thereby causing the baffle fixedly connected to the piston to move downward, so that the expansion structure is exposed in the uterine cavity. In addition, as the piston moves downward, the gas between the piston and the fixing plate is squeezed, and finally the gas is passed into the airbag from the inflation tube, inflating the airbag, causing the airbag to expand rapidly and fit the uterine cavity wall, thereby fixing the entire device in the uterine cavity. This fixing method is not only simple and efficient, but also can adapt to the physiological structure differences of the vagina of different parturient women, ensuring the stability of subsequent operations. Through the mutual cooperation among the electric telescopic rod, the fixed rod, the movable rod, the No. 1 sleeve, the No. 2 sleeve, the No. 3 sleeve, the cross connecting rod and the movable connecting rod, by starting the electric telescopic rod, the electric telescopic rod is retracted downward, thereby driving the No. 2 sleeve connected to the electric telescopic rod to move downward, and finally driving the movable rod and the fixed rod away from each other until the electric telescopic rod can no longer drive the No. 2 sleeve to move downward, indicating that the inner wall of the uterine cavity is stretched. The above operation can effectively expand the visual range inside the uterine cavity, eliminate the visual blind spots caused by uterine cavity folds and depressions, and create a spacious operating space for medical staff. Through the mutual cooperation of the electric telescopic rod, No. 1 sleeve, No. 2 sleeve, and silicone strip, when the electric telescopic rod drives No. 2 sleeve to descend, the distance between No. 1 sleeve and No. 2 sleeve is minimized, and the silicone strip between No. 1 sleeve and No. 2 sleeve is squeezed, so that the silicone strip bulges toward the inner wall of the uterine cavity. In this process, the dirt stuck to the inner wall of the uterine cavity can be scraped off, making it easier to clean later. Through the mutual cooperation of the connecting tube, the shell, the external water pipe, the flushing tube, the spiral column, the movable ring and the No. 2 sleeve, the movable ring is driven by the No. 2 sleeve and when the movable ring rises, due to the limitation of the spiral column on the flushing tube, the flushing tube can only spirally rise around the opening on the spiral column when the movable ring rises, and then the flushing tube can perform spiral all-round flushing of the inner wall of the uterine cavity during the spiral rising process, effectively removing impurities such as placental membrane tissue, lochia and blood congestion remaining in the uterine cavity; after flushing, the purpose of treating the inside of the uterine cavity can be achieved by connecting the connecting tube to the external medicine. Its use process is the same as the flushing process, except that water is replaced by medicine. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In obstetrics and gynecology clinical practice, postpartum recovery is a crucial step for women. The health of the uterine cavity directly affects the overall recovery process and subsequent fertility of the mother. The delivery process brings many changes to the uterine cavity, such as cervical lacerations, residual placental membranes, lochia, and other debris in the uterine cavity. These are not only prone to postpartum complications such as infection and bleeding, but may also lay the groundwork for long-term gynecological diseases. Therefore, please refer to Figures 1-12 The present application discloses an integrated auxiliary device for postpartum uterine cavity examination and treatment, including a shell 1 and an airbag 2 provided at the top of the shell 1. The shell 1 is a smooth cylinder, and a scale line 4 is marked on the outer wall of the shell 1 to facilitate observation of the depth of insertion into the uterine cavity. In order to facilitate the expansion of the inner wall of the uterine cavity, the visual range inside the uterine cavity is effectively expanded, and the visual blind spots caused by uterine cavity wrinkles and depressions are eliminated. At the same time, a spacious operating space is created for medical staff, which is convenient for performing delicate treatment operations such as uterine cavity flushing and medication. The present application also has: an inflation structure for inflating the airbag 2, an expansion structure for expanding the visual range inside the cavity; and a rotating flushing structure for all-round flushing of the inside of the uterine cavity. It should be noted that the maximum outer diameter of the airbag 2 after inflation is 10 mm, and the maximum outer diameter of the airbag 2 in the uninflated state is 7 mm, which is the same as the outer diameter of the shell 1.

[0038] Among them, the inflation structure is arranged inside the shell 1; the inflation structure includes: a piston component, which is clamped inside the shell 1 and located below the expansion structure; an inflation tube 15, which is located inside the shell 1, one end of which is connected to the inside of the airbag 2, and the other end is connected to the piston component.

[0039] Specifically, the piston assembly includes: a baffle 3, located on one side of the expansion structure and within the inner wall of the housing 1; a piston 22, located below the baffle 3 and fixedly connected to the baffle 3; a fixing plate 23, located below the piston 22; and a driver 24, located below the fixing plate 23 and connected to the piston 22. Specifically, the housing 1 in this application is made of medical plastic, and the piston 22 is a round rubber block that matches the dimensions of the interior of the housing 1. The overall length of the housing 1 and the airbag 2 is 30-35 cm, adapted to the anatomy of the female reproductive tract, ensuring smooth entry into the uterine cavity and completion of the operation. Furthermore, the housing 1 has an outer diameter of 7 mm, an inner diameter of 6 mm, and a thickness of 1 mm. The driver can be an electric telescopic rod, a hydraulic push rod, or other types. A hydraulic push rod is used as an example for illustration. A limit block 25 is provided below the hydraulic push rod to support and limit the hydraulic push rod. The hydraulic push rod model is xcj188, and specific specifications can be customized according to actual needs. The top end of the hydraulic push rod is bonded to the piston 22 , and the baffle 3 is bonded to the upper surface of the piston 22 . The opening at one end of the inflation tube 15 is located between the piston 22 and the limit block 25 , and the opening at the other end is located in the airbag 2 .

[0040] It should be noted that the baffle 3 is in the shape of an arc, which is adapted to the shape of the cylindrical shell 1. When the expansion structure is not expanded, the baffle 3 is used as a part of the shell 1. When the expansion structure needs to be expanded, the baffle 3 can be used as a structure independent of the shell.

[0041] During use, first extend the shell with one end of the airbag 2 into the patient's uterine cavity, then start the hydraulic push rod to drive the piston 22 to move downward, and then the baffle 3 fixedly connected to the piston 22 moves downward, so that the expansion structure is exposed in the uterine cavity. In addition, as the piston 22 moves downward, the gas between the piston 22 and the limit block 25 will be squeezed, and finally the gas will pass into the airbag 2 from the inflation tube 15, inflating the airbag 2, so that the airbag 2 expands rapidly and fits the uterine cavity wall, thereby fixing the entire device in the uterine cavity. This fixing method is not only simple and efficient, but also can adapt to the physiological structure differences of the vagina of different parturients, ensuring the stability of subsequent operations.

[0042] It should be noted that the housing 1 between the airbag 2 and the expansion structure is also equipped with a 360° rotating block. The rotating block is connected to the inflation tube 15 via a rotating shaft. The outer wall of the rotating shaft is also connected to a visual probe 5. The visual probe 5 is a model of the Shenbei audio and video life detector TC60C, which combines video imaging, audio and video infrared thermal imaging technology, and wireless transmission technology. The visual probe 5 can be electrically controlled to rotate 360° horizontally, allowing the visual probe 5 to capture extremely subtle image information within the uterine cavity. The visual probe 5 has a 360° rotation function. Medical staff can flexibly adjust the viewing angle through an external control device to scan the cervix and the interior of the uterine cavity in all directions, accurately locating lesions such as cervical lacerations, the location of residual placental membranes, and abnormal changes in the endometrium, providing a reliable basis for subsequent diagnosis and treatment.

[0043] After the device is stabilized inside the uterine cavity, the uterine cavity needs to be expanded to facilitate the visual probe to inspect the inside of the uterine cavity. Therefore, the present application also provides an expansion structure, which is located inside the shell corresponding to the baffle and below the airbag 2.

[0044] Specifically, the expansion structure includes: a driving component, which is arranged inside the shell 1; and a connecting rod component, which is located inside the shell 1 and connected to the driving component.

[0045] The driving component includes: a support base 14, which is located below the connecting rod component; and an electric telescopic rod 26, which is located above the support base 14 and connected to the connecting rod component.

[0046] The connecting rod components include: a fixed rod 6, located above the support seat 14 and bonded and fixed to the support seat 14; a plurality of movable rods 7, located above the support seat 14 and respectively connected to the fixed rod 6; and a plurality of movable components, respectively located on the fixed rod 6 and the plurality of movable rods 7.

[0047] Each movable assembly includes: a plurality of sleeves sleeved on the fixed rod 6 and the movable rod 7; a cross link 11 located between the fixed rod 6 and the plurality of movable rods 7 and movably connected to the sleeves.

[0048] like Figure 4As shown, three sleeves are respectively provided on the fixed rod 6 and each movable rod 7, which are No. 1 sleeve 8, No. 2 sleeve 9, and No. 3 sleeve 10 from bottom to top, wherein each No. 2 sleeve 9 is movably connected to its corresponding movable rod 7 or fixed rod 6, and each No. 1 sleeve 8 and No. 3 sleeve 10 are fixedly connected to its corresponding movable rod 7 or fixed rod 6; the fixed rod 6 and the No. 1 sleeve 8 and No. 2 sleeve 9 on each movable rod 7 are cross-connected by a cross-link 11. The two movable rods 7 near the left and right sides of the fixed rod 6 are used as an example for explanation. The No. 2 sleeve 9 on the above two movable rods 6 is connected to the No. 1 sleeve on the fixed rod 6. 8 is movably connected by a rotating shaft, the No. 1 sleeve 8 on the above-mentioned two movable rods 7 is movably connected to the No. 2 sleeve 9 on the fixed rod 6 by a rotating shaft, and the connection relationship between the remaining multiple movable rods 7 is the same as the connection relationship between the fixed rod 6 and the movable rod 7, and no more details are given here; the fixed rod 6 and the No. 3 sleeve 10 on each movable rod 7 are movably connected by a movable connecting rod 12, and the movable connecting rod 12 is composed of two short rods, and the ends of the two short rods that are close to each other are movably connected by a rotating shaft, and the ends of the two short rods that are away from each other are respectively movably connected to the fixed rod 6 and the movable rod 7, and the movable rods 7 and the movable rods 7 are movably connected by a rotating shaft.

[0049] In addition, the fixed rod 6, each movable rod 7, each sleeve, each movable link 12 and the cross link 11 are all made of metal, such as titanium alloy or stainless steel, which is not limited here and can be selected according to actual conditions. The outer diameter of the fixed rod 6 and each movable rod 7 is 1 mm and the length is 50 mm; the outer diameter of the sleeves sleeved on the fixed rod 6 and each movable rod 7 is 1.5 mm, such as Figure 8 As shown, the movable connecting rod 12 and the cross connecting rod 11 located between each sleeve are hinged and movable. When the fixed rod 6 and the multiple movable rods 7 are stretched to the maximum extent, the outer diameter is 10 mm, and when contracted, the outer diameter is 5-6 mm, which matches the inner diameter of the shell.

[0050] It should be noted that the movable end of the electric telescopic rod 26 is fixedly connected to the No. 2 sleeve 9 fixedly sleeved on the fixed rod 6. When the electric telescopic rod 26 drives the No. 2 sleeve 9 to move up and down on the fixed rod 6, since each No. 2 sleeve 9 is cross-hinged and connected to each No. 3 sleeve 10, and the length of the cross-link 11 remains unchanged, when the No. 2 sleeve 9 moves upward, in order to keep the length of the cross-link 11 unchanged, the movable rod 7 will move toward the fixed rod. When moving, the two short rods of the cross-link 11 connecting the No. 3 sleeve 10 will also move around between them. When the fixed rod 6 and the movable rod 7 in the retracted state need to be expanded, the electric telescopic rod 26 is started to retract downward, thereby driving the No. 2 sleeve 9 connected to the electric telescopic rod 26 to move downward, and finally driving the movable rod 7 and the fixed rod 6 to move away from each other until the electric telescopic rod 26 can no longer drive the No. 2 sleeve 9 to move downward, which means that the expansion has been maximized.

[0051] Preferably, in order to scrape off the dirt stuck on the inner wall of the uterine cavity and facilitate subsequent cleaning, the present application also provides a silicone strip 13 between the No. 1 sleeve 8 and the No. 2 sleeve 9. The two ends of the silicone strip 13 are fixedly connected to the No. 1 sleeve 8 and the No. 2 sleeve 9 respectively, and the outer wall of the silicone strip 13 is also provided with a plurality of protrusions for increasing the friction between the silicone strip 13 and the inner wall of the uterine cavity, so as to facilitate better scraping off of the dirt.

[0052] When the expansion structure is in the process of expansion, the distance between the No. 1 sleeve 8 and the No. 2 sleeve 9 will gradually become smaller, squeezing the silicone strip 13 between the No. 1 sleeve 8 and the No. 2 sleeve 9, so that the silicone strip 13 bulges toward the inner wall of the uterine cavity, and dirt can be scraped off in the process; when the expansion structure is contracted, the distance between the No. 1 sleeve 8 and the No. 2 sleeve 9 becomes larger, thereby stretching the silicone strip 13, so that the silicone strip 13 is in a stretched state, making it easier for the silicone strip 13 and the fixed rod 6 and the movable rod 7 to be contracted inside the shell 1.

[0053] In order to allow the inner wall of the uterine cavity to be expanded by the expansion structure and to observe the inside of the uterine cavity more clearly when there is blood or other stains inside the uterine cavity, the present application also provides a rotating flushing structure that can perform all-round flushing of the inner wall of the uterine cavity. The structure is arranged inside the shell 1, between the expansion structures, and connected to the expansion structure for all-round flushing of the inside of the uterine cavity.

[0054] Specifically, the rotary flushing structure includes: a rotating component located between the connecting rod components and connected to one of the multiple sleeves; and a flushing component located between the rotating components and connected to the rotating components.

[0055] The rotating part includes: a moving ring 17, which is connected to one of the multiple sleeves; a spiral column 16, which is fixedly connected to the support base 14 and is located in the middle of the moving ring 17. Specifically, the moving ring 17 is connected to the second sleeve 9 on the fixed rod 6. When the second sleeve 9 moves up or down, it will synchronously drive the moving ring 17 to move up or down; Figure 12 As shown, the spiral column 16 is spirally provided with an opening.

[0056] The flushing component includes: a connecting tube 19, which is inserted into the housing 1 and connected to the external water pipe; a flushing tube 18, which is located outside the spiral column 16 and is movably connected to the connecting tube 19 via a rotating shaft. In addition, the bottom of the flushing tube 18 is movably connected to the movable ring 17 via the connecting column. When the second sleeve 9 on the fixed rod 6 drives the movable ring 17 to rise, the spiral column 16 limits the flushing tube 18, so that the flushing tube 18 can only spirally rise around the opening on the spiral column 16 when the movable ring 17 rises. As a result, the flushing tube 18 can spirally and comprehensively flush the inner wall of the uterine cavity during the spiral rise, effectively removing impurities such as placental membrane tissue, lochia, and blood stasis remaining in the uterine cavity. After flushing, the visual probe 5 can easily observe the interior of the uterine cavity.

[0057] It should be noted that the rotary flushing structure of the present application can also achieve the purpose of treating the inside of the uterine cavity by connecting the connecting tube 19 to the external medicinal solution after flushing. Its usage process is the same as the flushing process, except that water is replaced by medicinal solution, which will not be elaborated here.

[0058] After flushing is completed, the present application is also provided with a discharge component, which includes a sealing airbag 20 mounted on the outside of the shell 1 and a discharge tube 21 with an opening facing the outside of the shell. When it is necessary to discharge the waste water flushed inside the cervix, the air pump externally connected to the sealing airbag 20 can be opened to inflate the sealing airbag 20, thereby blocking the inside of the cervix to prevent the waste water from flowing out of the cervix and flowing everywhere, which is difficult to clean. Then the discharge end of the discharge tube 21 is connected to the external water pump and the collection box to directly suck the waste water to the outside of the cervix. Example 1

[0059] The main steps of hysteroscopy include: 1. Preoperative preparation: Before the examination, the doctor will inquire about the patient's medical history in detail and conduct a comprehensive physical examination, including a gynecological examination, blood routine, coagulation function, and infectious disease screening, to assess the patient's suitability for a hysteroscopy. The patient should abstain from sexual intercourse and maintain vulvar hygiene before the examination. The examination is generally performed 3-7 days after the end of menstruation, when the endometrium is thinner and easier to observe.

[0060] 2. Anesthesia: The appropriate anesthesia method is selected based on the patient's specific condition and examination requirements. Common anesthesia methods include local anesthesia and general anesthesia. Local anesthesia involves injecting anesthetic drugs into the cervix to relieve pain during cervical dilation. General anesthesia is suitable for patients who are more sensitive to pain or require complex procedures.

[0061] 3. Dilate the cervix and insert the auxiliary device for examination: The patient takes the lithotomy position, and the doctor disinfects the vulva, vagina and cervix. Then, the integrated auxiliary device for postpartum uterine cavity examination and treatment of the present application is used to examine the inside of the patient's cervix. During the examination, the shell with one end of the airbag 2 is first inserted into the patient's uterine cavity, and then the hydraulic push rod is started to drive the piston 22 to move downward, thereby causing the baffle 3 fixedly connected to the piston 22 to move downward, so that the expansion structure is exposed in the uterine cavity. Moreover, as the piston 22 moves downward, the gas between the piston 22 and the limit block 25 is squeezed, and finally the gas is passed into the airbag 2 from the inflation tube 15, and the airbag 2 is inflated, so that the airbag 2 expands rapidly and fits the uterine cavity wall, thereby fixing the entire device in the uterine cavity. This fixing method is not only simple and efficient, but also can adapt to the physiological structure differences of the vagina of different parturient women, ensuring the stability of subsequent operations. Then, by starting the electric telescopic rod, the electric telescopic rod is retracted downward, thereby driving the No. 2 sleeve connected to the electric telescopic rod to move downward, and finally driving the movable rod and the fixed rod to move away from each other, until the electric telescopic rod can no longer drive the No. 2 sleeve to move downward, which indicates that the inner wall of the uterine cavity is stretched. The above operation can effectively expand the visual range inside the uterine cavity, eliminate the visual blind spots caused by uterine cavity folds and depressions, and create a spacious operating space for medical staff. Finally, medical staff can flexibly adjust the viewing angle of the visual probe 5 through the external control device, scan the cervix and the inside of the uterine cavity in all directions, and accurately locate lesions such as whether there are lacerations in the cervix, the position of residual placental membranes, and abnormal changes in the endometrium, providing a reliable basis for subsequent diagnosis and treatment.

[0062] 4. End of the examination: After the examination is complete, the hysteroscope is slowly removed and the uterine distention fluid is drained as much as possible. Based on the examination results, the doctor will decide whether to remove tissue for pathological examination. If there is a lesion, simple treatment may be performed during the examination, such as removal of a small polyp.

[0063] After a hysteroscopy, it's important to rest and avoid strenuous exercise and heavy labor. One to two days of rest are generally recommended. A small amount of vaginal bleeding may occur after the procedure, which is normal. Maintain clean vulva hygiene and change underwear and sanitary napkins frequently. If any abnormalities, such as heavy bleeding, increased abdominal pain, or fever, occur, seek medical attention promptly. Example 2

[0064] Based on Example 1 of the present application, if dirt is found attached to the inner wall of the cervix during the inspection, it can be scraped off and then cleaned. The specific operation is: during the expansion of the expansion structure, since the distance between the No. 1 sleeve 8 and the No. 2 sleeve 9 will gradually become smaller, the silicone strip 13 between the No. 1 sleeve 8 and the No. 2 sleeve 9 will be squeezed, so that the silicone strip 13 bulges toward the inner wall of the uterine cavity, and the outer wall of the silicone strip is also provided with a plurality of protrusions, which are used to increase the friction between the silicone strip and the inner wall of the uterine cavity, so as to facilitate better scraping of the dirt. During the expansion process of the expansion structure, the external water pipe can also be connected to the connecting pipe 19, so that when the No. 2 sleeve 9 on the fixed rod 6 drives the movable ring 17 to rise, due to the limitation of the spiral column 16 on the flushing tube 18, the flushing tube 18 can only spirally rise around the opening on the spiral column 16 when the movable ring 17 rises, and then the flushing tube 18 can perform spiral all-round flushing of the inner wall of the uterine cavity during the spiral rising process, effectively removing impurities such as placental membrane tissue, lochia and blood congestion remaining in the uterine cavity.

[0065] After flushing is completed, when it is necessary to discharge the waste water flushing the inside of the cervix, the air pump connected to the external blocking airbag 20 can be opened to inflate the blocking airbag 20, and then the discharge end of the discharge tube 21 can be connected to the external water pump and the collection box to directly suck the waste water to the outside of the cervix.
