[0024] See also Figure 1-Figure 7 The present invention provides a vaginal opening blocking device for colposcopy, including a sealing ring 100, a rubber membrane 200 fixed on one side of the sealing ring 100, and three through holes 201 formed on one side of the rubber membrane 200, an inner plate 300 fixed on the other side of the sealing ring 100, and three openings 301 formed on one side of the inner plate 300, a sleeve 302 fixed in the opening 301, a silicone sleeve 303 fixed in the sleeve 302, and an inner diameter of the silicone sleeve 303 being smaller than the inner diameter of the corresponding through hole 201.
[0025] As a further solution of the present invention, a silicone ring 101 is fixed to the side of the sealing ring 100 away from the through hole 201 , and the inner diameter of the silicone ring 101 is smaller than the inner diameter of the sealing ring 100 .
[0026] By setting the silicone ring 101, the silicone ring 101 can fit with the surface of the perineum to prevent the liquid discharged from the vaginal opening from leaking. The sealing fit of the silicone ring 101 allows the liquid to flow into the sealing ring 100, thereby collecting the liquid. By setting the inner diameter of the silicone ring 101 to be smaller than the inner diameter of the sealing ring 100, when the liquid flows into the sealing ring 100, the silicone ring 101 can form a blocking effect on the liquid in the sealing ring 100, preventing the liquid from flowing back to the position below the vaginal opening, causing the liquid in the sealing ring 100 to flow out after the entire device is removed.
[0027] This solution has the following working process: when sealing the vaginal opening, the patient first needs to put the two first elastic strips 400 respectively from the two legs, then the patient lies on the operating table and lifts the two legs to bend them, then the medical staff holds the sealing ring 100 and adjusts the position of the silicone ring 101 so that the silicone ring 101 fits the surface of the patient's perineum. At this time, the silicone ring 101 completely wraps the perineum, and the elastic band 602 contacts the skin on both sides of the perineum. Then the medical staff adjusts the position of the first elastic strips 400 on both sides so that the first elastic strips 400 are located on the patient's The patient then pulls the third elastic strip 402, causing the two first elastic strips 400 to be pulled, causing the silicone ring 101 to fit tightly against the patient's perineum. During this process, the elastic band 602 is stretched, allowing it to fit tightly against the skin on both sides of the perineum. The primary Velcro 403 and secondary Velcro 404 are then bonded together, completing the device installation. Once the device is installed, the elastic band 602 can distribute the pressure distribution of the silicone ring 101, reducing the pressure exerted by the silicone ring 101 on the perineum and preventing marks and discomfort. The medical professional then inserts the water delivery line through the central through-hole 201, passes through the corresponding silicone sleeve 303, and enters the vagina. Water can then be injected into the vagina to expand the vaginal wall, and the delivery line can then be removed. Excess water will flow into the sealing ring 100 between the inner plate 300 and the silicone ring 101, and then into the drainage hole 502 for storage. Afterwards, the medical staff inserts the endoscope through the corresponding through hole 201 and finally through the corresponding silicone sleeve 303. Since the inner diameters of the silicone sleeve 303 and the through hole 201 are smaller than the inner diameter of the surgical instrument, after the endoscope passes through the through hole 201 and the silicone sleeve 303, the rubber membrane 200 and the silicone sleeve 303 can fit tightly with the outer wall of the endoscope to form a tight sealing state. The silicone ring 101 forms the first seal and the rubber membrane 200 forms the second seal. Then, the operating instrument can be inserted into another through hole 201 and silicone sleeve 303 accordingly. The rubber membrane 200 and the silicone sleeve 303 can fit tightly with the outer wall of the operating instrument to form a tight sealing state. After that, the medical staff can examine the vagina according to the operating endoscope and the operating instrument. When medical personnel operate the endoscope and operating instruments to inspect the vaginal opening, the liquid flowing out of the vaginal opening will enter the sealing ring 100 and then enter the drainage hole 502, so that the liquid can be collected. Since the silicone ring 101 is tightly attached to the surface of the perineum, the liquid will not leak to the outside of the device. After the inspection is completed, the medical personnel remove the endoscope and operating instruments. Since the rubber membrane 200 and the silicone sleeve 303 are tightly attached to the outer walls of the endoscope and operating instruments, when the endoscope and operating instruments are removed, the liquid on the endoscope and operating instruments is scraped off by the rubber membrane 200 and the silicone sleeve 303. After the endoscope and operating instruments are removed, there will not be much liquid left on their surface, avoiding excessive liquid on the surface of the operating instruments and endoscope, causing liquid dripping.During the inspection, medical staff can use an endoscope to observe whether the liquid in the sealing ring 100 overflows the silicone ring 101. If so, they can place a small collection bucket under the drainage pipe 500, then open the sealing plug 501 to allow the liquid in the sealing ring 100 and the drainage hole 502 to drain into the small collection bucket, and then seal the sealing plug 501 again before continuing the inspection. After the inspection, the sealing plug 501 also needs to be opened to allow the liquid in the sealing ring 100 and the drainage hole 502 to drain, and then the device can be removed.
[0028] According to the above working process, it can be seen that: by setting a silicone ring 101 that adapts to the shape of the perineum, the silicone ring 101 can be stably fitted with the perineum, and by setting the inner plate 300 and the silicone sleeve 303, a first seal can be formed on the vaginal opening; by setting the rubber membrane 200 and the through hole 201, a second seal can be formed on the vaginal opening, thereby stably sealing the vaginal opening and ensuring that surgical instruments can pass through, avoiding the problems of low sealing reliability, poor operating convenience and high medical risks caused by using traditional methods.
[0029] By setting the inner diameter of the silicone ring 101 to be smaller than the inner diameter of the sealing ring 100, when the liquid flows into the sealing ring 100, the silicone ring 101 can form a blocking effect on the liquid in the sealing ring 100, preventing the liquid from flowing back to the position below the vaginal opening, causing the liquid in the sealing ring 100 to flow out after the entire device is removed.
[0030] By providing the drainage hole 502 , the drainage tube 500 and the sealing plug 501 , the liquid flowing out of the vaginal opening can be collected and stored.
[0031] By setting the silicone sleeve 303 and rubber membrane 200, when medical staff take out the endoscope and operating instruments, the rubber membrane 200 and silicone sleeve 303 are in close contact with the outer walls of the endoscope and operating instruments, and the liquid on the endoscope and operating instruments is scraped off by the rubber membrane 200 and silicone sleeve 303, so that after the endoscope and operating instruments are taken out, there will not be much liquid remaining on their surface, avoiding excessive liquid on the surface of the operating instruments and endoscope, causing liquid dripping.
[0032] By setting the elastic band 602 and the rotating bar 601, the elastic band 602 can share the pressure distribution of the silicone ring 101 after the device is installed, so that the pressure exerted by the silicone ring 101 on the perineum is reduced, avoiding marks and discomfort on the patient's perineum.
[0033] As a further solution of the present invention, a drainage hole 502 is opened at the bottom of the inner wall of the sealing ring 100, and the drainage hole 502 is located between the inner plate 300 and the silicone ring 101. A drainage pipe 500 is fixed to the bottom of the outer wall of the sealing ring 100, and the drainage pipe 500 corresponds to the drainage hole 502. A sealing plug 501 is detachably connected to the drainage pipe 500.
[0034] The drainage hole 502 is provided so that the liquid in the sealing ring 100 can enter the drainage hole 502, which on the one hand increases the liquid storage space, and on the other hand prevents excessive liquid from flowing out of the vaginal opening, causing the storage space in the sealing ring 100 to be filled up, resulting in liquid passing over the silicone ring 101, causing the liquid in the sealing ring 100 to flow out after the entire device is removed.
[0035] As a further solution of the present invention, first elastic strips 400 are fixed on both sides of the outer wall of the sealing ring 100.
[0036] By setting the first elastic strip 400, the female patient can bend and lift her legs after her legs are respectively put into the first elastic strip 400, so that the first elastic strips 400 on both sides can generate a pulling force on the sealing ring 100, thereby allowing the silicone ring 101 to fit the patient's perineum. This setting allows the entire device to be fixed on the patient's perineum, thereby sealing the patient's vaginal opening.
[0037] As a further solution of the present invention, second elastic strips 401 are fixed on both sides of the first elastic strip 400, and a third elastic strip 402 is fixed at one end of the four second elastic strips 401. A secondary Velcro 404 is fixed on one side of the outer wall of the third elastic strip 402, and a main Velcro 403 is fixed on one side of the inner wall of the third elastic strip 402.
[0038] By setting the main Velcro 403 and the auxiliary Velcro 404, the two ends of the third elastic strip 402 can be connected together; by setting the second elastic strip 401 and the third elastic strip 402, the third elastic strip 402 can be wrapped around the patient's waist, and then the second elastic strip 401 can pull the first elastic strip 400, so that the silicone ring 101 can be close to the perineum, avoiding the patient's legs moving during the examination, causing the silicone ring 101 to separate from the perineum, affecting the sealing effect of the vaginal opening.
[0039] As a further solution of the present invention, the sealing ring 100 is provided with four grooves 600 on the side away from the rubber membrane 200, and a rotating bar 601 is movably connected between the two side surfaces of the inner wall of the groove 600, and an elastic band 602 is fixed between one end of the two rotating bars 601.
[0040] By setting the rotating strip 601 and the elastic band 602, after the elastic band 602 contacts the patient's perineum, the positions of the first elastic strip 400 and the third elastic strip 402 are adjusted so that the elastic band 602 shares part of the pressure of the silicone ring 101, thereby avoiding the direct use of the silicone ring 101, which may cause marks and discomfort on the patient's perineum.
[0041] As a further solution of the present invention, an arc-shaped hole 605 is provided on the inner wall of the slot 600 close to the rubber membrane 200, and an arc-shaped rod 603 is fixed on the side of the rotating bar 601 close to the arc-shaped hole 605. One end of the arc-shaped rod 603 is located in the arc-shaped hole 605, and a spring 604 is provided on the outer wall of the arc-shaped rod 603. One end of the spring 604 is fixed to one side of the rotating bar 601, and the other end of the spring 604 is fixed to one side of the inner wall of the slot 600.
[0042] The spring 604 can be limited by the provided arc-shaped rod 603 , and the initial position of the rotating bar 601 can be limited by the provided spring 604 .
[0043] As a further solution of the present invention, the bottom surface of the inner wall of the silicone ring 101 is an arc-shaped inclined surface.
[0044] By setting the bottom surface of the inner side wall of the silicone ring 101 as an arc-shaped slope, the liquid flowing out of the vaginal opening can smoothly enter the sealing ring 100 from the arc-shaped slope, avoiding the accumulation of liquid on the bottom surface of the silicone ring 101.
[0045] In summary: when sealing the vaginal opening, the patient first needs to put the two first elastic strips 400 into the two legs respectively, then the patient lies on the operating table and lifts the two legs to bend them. Then the medical staff holds the sealing ring 100 and adjusts the position of the silicone ring 101 so that the silicone ring 101 fits the surface of the patient's perineum. At this time, the silicone ring 101 completely wraps the perineum, and the elastic band 602 contacts the skin on both sides of the perineum. Then the medical staff adjusts the position of the first elastic strips 400 on both sides so that the first elastic strips 400 are located at the base of the patient's thighs. Then, the third elastic strip 402 is pulled, causing the two first elastic strips 400 to be pulled. The silicone ring 101 now fits tightly against the patient's perineum. During this process, the elastic band 602 is stretched, allowing it to fit tightly against the skin on both sides of the perineum. The main Velcro 403 and the secondary Velcro 404 are then bonded together, completing the device installation. After the device is installed, the elastic band 602 can distribute the pressure distribution of the silicone ring 101, reducing the pressure exerted by the silicone ring 101 on the perineum and preventing marks and discomfort on the patient's perineum. The medical professional then inserts the water delivery line through the central through-hole 201, passes through the corresponding silicone sleeve 303, and enters the vagina. Water can then be injected into the vagina to expand the vaginal wall, and the delivery line can then be removed. Excess water will flow into the sealing ring 100 between the inner plate 300 and the silicone ring 101, and then into the drainage hole 502 for storage. Afterwards, the medical staff inserts the endoscope through the corresponding through hole 201 and finally through the corresponding silicone sleeve 303. Since the inner diameters of the silicone sleeve 303 and the through hole 201 are smaller than the inner diameter of the surgical instrument, after the endoscope passes through the through hole 201 and the silicone sleeve 303, the rubber membrane 200 and the silicone sleeve 303 can fit tightly with the outer wall of the endoscope to form a tight sealing state. The silicone ring 101 forms the first seal and the rubber membrane 200 forms the second seal. Then, the operating instrument can be inserted into another through hole 201 and silicone sleeve 303 accordingly. The rubber membrane 200 and the silicone sleeve 303 can fit tightly with the outer wall of the operating instrument to form a tight sealing state. After that, the medical staff can examine the vagina according to the operating endoscope and the operating instrument. When medical personnel operate the endoscope and operating instruments to inspect the vaginal opening, the liquid flowing out of the vaginal opening will enter the sealing ring 100 and then enter the drainage hole 502, so that the liquid can be collected. Since the silicone ring 101 is tightly attached to the surface of the perineum, the liquid will not leak to the outside of the device. After the inspection is completed, the medical personnel remove the endoscope and operating instruments. Since the rubber membrane 200 and the silicone sleeve 303 are tightly attached to the outer walls of the endoscope and operating instruments, when the endoscope and operating instruments are removed, the liquid on the endoscope and operating instruments is scraped off by the rubber membrane 200 and the silicone sleeve 303. After the endoscope and operating instruments are removed, there will not be much liquid left on their surface, avoiding excessive liquid on the surface of the operating instruments and endoscope, causing liquid dripping.During the examination, the medical staff can observe through the endoscope whether the liquid in the sealing ring 100 overflows the silica gel ring 101, if such a situation occurs, the collection bucket can be placed below the liquid discharge pipe 500, then the sealing plug 501 is opened, so that the liquid in the sealing ring 100 and the liquid discharge hole 502 is discharged into the collection bucket, then the sealing plug 501 is sealed, and the examination can be performed. After the examination, the sealing plug 501 also needs to be opened, so that the liquid in the sealing ring 100 and the liquid discharge hole 502 is discharged, and then the device can be removed.
[0046] Among them, the inner diameters of the three silica gel sleeves 303 are different, and the inner diameters of the three through holes 201 are different.
[0047] The inner diameters of the silica gel sleeves 303 and the through holes 201 are smaller than the inner diameter of the surgical instrument.
[0048] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
