Description

Technical Field

[0001] The present invention relates to the technical field of cervical biopsy sampling, and particularly to an obstetrics and gynecology cervical sampling device. Background Art

[0002] As is well known, cervical biopsy is the most reliable basis for diagnosing cervical cancer and precancerous lesions. When abnormal cells are found in cervical cytology examinations, such as atypical squamous cells, low-grade squamous intraepithelial lesions, high-grade squamous intraepithelial lesions, etc., cervical biopsy is required to clarify whether there is cervical cancer or precancerous lesions. For some cases of chronic cervicitis, such as long-term non-healing cervical erosion, cervical polyps, etc., biopsy can help doctors judge the type and severity of the inflammation.

[0003] After retrieval, a Chinese patent discloses a cervical biopsy forceps, the application publication number of which is CN106137269B. The patent has a housing and a sampling head, and the sampling head is installed at the front end of the housing. A disinfection device is also installed at the front end of the housing. The cervical biopsy forceps provided by this application has a disinfection device installed at the front end of the housing, which can disinfect the uterus during or after sampling, avoiding the secondary injury caused by the need to take out the cervical biopsy forceps after sampling and then insert the disinfection device into the cervix for disinfection in the prior art.

[0004] When performing cervical biopsy, a sampling device is needed. In the prior art, such operations are mostly carried out by using a dilator to expand the vagina and cutting off some suspicious tissues at the cervix with a biopsy forceps for examination. Usually, since the dilator itself is a rigid structure, not only is it easy to cause temperature stimulation to the vagina when the ambient temperature is low, but the discomfort caused is also relatively serious. And since the cutting end of the biopsy forceps is usually far from the holding position when held by a person, and the person will also shake when applying force to cut, it is easy to cause an error in the cutting position. Based on the above-mentioned problems, we found that it is difficult for the existing gynecological cervical sampling devices to avoid the above problems at the same time. Therefore, we propose an obstetrics and gynecology cervical sampling device that can assist in supporting the sampling structure during sampling, can perform pre-positioning before cutting to avoid deviation of the cutting position, and at the same time reduce the stimulation to the vagina of the examined person. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an obstetrics and gynecology cervical sampling device, which has the advantages of being able to assist in supporting the sampling structure during sampling, being able to perform pre-positioning before cutting to avoid deviation of the cutting position, and at the same time reducing the stimulation to the vagina of the examined person.

[0006] The above technical object of the present invention is achieved through the following technical solutions: An obstetrics and gynecology cervical sampling device includes an upper opening forceps and a lower opening forceps. The upper opening forceps is provided at the top of the lower opening forceps. A rotating pin is rotatably connected to the outside of the upper opening forceps, and the inside of the lower opening forceps is rotatably connected to the rotating pin. Contact sacs are provided on the inside of both the upper opening forceps and the lower opening forceps. A sampling tube is provided between the upper opening forceps and the lower opening forceps; The sampling tube includes an integrally formed collection tube and a bottom tube. The collection tube is provided at the top of the bottom tube. An integrally formed extension section is provided on the right side of the bottom tube. An air pump is installed inside the collection tube, and the top of the air pump is provided inside the collection tube. An interception net plate is fixedly connected inside the collection tube, and a truncation mechanism is provided inside the collection tube; The truncation mechanism includes a constriction mask. A flat plate cavity is fixedly connected to the top inside the collection tube. A piston piece is slidably connected inside the flat plate cavity. A blade is fixedly connected to the bottom of the piston piece. The bottom of the blade penetrates through the constriction mask and is movably connected to the constriction mask. A guiding cover is integrally formed on the right side of the constriction mask. A transmission tube is fixedly connected to the top on the left side of the flat plate cavity. The side of the transmission tube away from the flat plate cavity penetrates through the bottom of the bottom tube and extends out from the inside of the extension section.

[0007] With the above technical solution, by setting the upper opening forceps and the lower opening forceps as the vaginal auxiliary dilation structure during sampling, the upper opening forceps can rotate along the rotating pin to facilitate the opening of the upper opening forceps and the lower opening forceps for vaginal dilation. The upper opening forceps and the lower opening forceps will contact the vaginal inner wall through the contact sac made of flexible material to improve the degree of fitting with the vaginal inner wall and reduce irritation. The sampling tube is connected to the lower opening forceps. After the positions of the upper opening forceps and the lower opening forceps are relatively fixed, it can play a certain auxiliary supporting role for the sampling tube. When a person holds the sampling tube to move during sampling, it is not easy to shake, etc., so as to reduce the possibility of sampling position deviation. During the sampling process, hold the position of the extension section and extend it inward along the lower opening forceps until the collection tube contacts the sampling position. Then, the angle of the sampling tube can be adjusted to fit the sampling position. The inspection position is pressed and will fit the shrinkage mask of the truncation mechanism and recess a part. The air pump extracts gas to make the left opening position of the collection tube negative pressure. At this time, the inspection position is further sucked into the collection tube. At this time, the sampling position can be observed. If it is not the position to be sampled, the air pump extraction can be stopped and the position can be changed. If the sampling position is determined, gas can be blown into the interior of the transmission tube. The gas is filled into the flat cavity and pushes the piston piece and the blade to press down along the flat cavity, cutting off the sampled part and making it approach the air pump under the influence of the air flow. After being intercepted by the intercepting net plate, it will fall into the bottom tube. This can not only avoid sampling errors that may be caused by directly shearing tissues, but also ensure that the tissue sizes obtained each time are consistent. After that, the structure can be taken out, and the tissue can be taken out from the bottom of the collection tube for inspection.

[0008] The present invention is further configured as: the contact sac includes a silica gel outer layer, a rubber inner layer is provided inside the silica gel outer layer, a heating medium is filled inside the rubber inner layer, an insulating cotton filling layer is provided between the silica gel outer layer and the rubber inner layer, and a heating wire is installed inside the rubber inner layer.

[0009] With the above technical solution, by directly contacting the relatively soft silica gel outer layer with the vaginal inner wall, it can undergo a certain deformation when stressed. The rubber inner layer has a relatively hard texture, which can not only withstand high temperatures to a certain extent, but also play a good storage effect on liquid media. Before sampling, the heating medium can be preheated by the heating wire to make the structure temperature close to the body temperature of the test subject, further reducing discomfort.

[0010] The present invention is further configured as: assembly pieces are fixedly connected to the inner sides of both the upper opening forceps and the lower opening forceps. A riveting pin is provided inside the assembly piece. The riveting pin penetrates through the silica gel outer layer and the rubber inner layer on the outer side and is adhesively bonded to the rubber inner layer through waterproof glue.

[0011] With the above technical solution, by setting the assembly piece in cooperation with the riveting pin, it is convenient to firmly connect the contact capsule and the upper opening clamp or the lower opening clamp, and the leakage of liquid at the connection can be reduced by bonding with waterproof glue.

[0012] The present invention is further configured as: a narrow frame is fixedly connected to the bottom inside the lower opening clamp, a sliding sleeve is slidably connected to the outside of the narrow frame, and the top of the sliding sleeve is movably connected to the sampling tube.

[0013] With the above technical solution, by setting the narrow frame in cooperation with the sliding sleeve, it is convenient to horizontally move the sampling tube along the lower opening clamp, and the moving path of the sampling tube is limited to avoid large-angle inclination or rotation, and to assist in supporting the sampling tube.

[0014] The present invention is further configured as: a sliding ball is fixedly connected to the top of the sliding sleeve, a ball joint is slidably connected to the inside of the sliding ball, and the outside of the collecting tube and the bottom tube are both fixedly connected to the ball joint.

[0015] With the above technical solution, by setting the sliding ball in cooperation with the ball joint, when the person holds the extension section and needs to adjust the sampling position, the ball joint connected to the collecting tube and the bottom tube will slide in the sliding ball, making the structure move more flexibly, and at the same time making the structure more stable when adjusting the position.

[0016] The present invention is further configured as: a body exterior is fixedly connected to the bottom on the right side of the lower opening clamp, an outer hoop is fixedly connected to the outside of the body exterior, a threaded rod is threadedly connected to the inside of the outer hoop, and the top of the threaded rod is movably connected to the upper opening clamp.

[0017] With the above technical solution, by setting the body exterior, when sampling and inspecting, the right sides of the lower opening clamp and the upper opening clamp are limited outside the person's body, avoiding the difficulty of taking out caused by excessive penetration, and at the same time making it convenient for the person to operate or observe the internal structure on the right sides of the upper opening clamp and the lower opening clamp. The outer hoop and the threaded rod drive the structure. When the threaded rod is rotated along the outer hoop, the right side of the upper opening clamp will be pulled to rotate downward along the rotating pin and open relative to the lower opening clamp.

[0018] The present invention is further configured as: a sample groove is provided at the top of the bottom tube, two isolation sheets are fixedly connected to the inside of the bottom tube, the outside of the transmission tube penetrates through the isolation sheets and is fixedly connected to the isolation sheets, and a supplementary light is fixedly connected to the left side of the bottom tube.

[0019] With the above technical solution, by setting the isolation sheets, the airtightness of the structure can be improved, and at the same time, the falling sample tissue can be protected and temporarily stored and limited. The provided supplementary light can facilitate providing a certain amount of illumination for observing the cervical position during sampling.

[0020] The present invention is further configured such that: a narrow groove is provided at the bottom of the bottom tube, a push piece is slidably connected to the inner side of the narrow groove, a return spring is fixedly connected to the right side of the push piece, and the right side of the return spring is fixedly connected to the right side of the inner side of the narrow groove.

[0021] With the above technical solution, by arranging the push piece at the bottom of the bottom tube, the sample tissue will be picked up when it falls, and when the sample tissue needs to be taken out, the push piece can be slid along the narrow groove to expose the inner space of the bottom tube, at this time the sample tissue will fall, and the arranged return spring can deform when the push piece is moved, and reset when the person stops pushing to reset the structure.

[0022] The present invention is further configured such that: an empty tube is fixedly connected to the right side of the transmission tube, a piston block is slidably connected to the inner side of the empty tube, a sliding rod is fixedly connected to the bottom of the piston block, the outer side of the sliding rod is slidably connected to the empty tube, a pulling spring is fixedly connected to the bottom of the piston block, and the bottom of the pulling spring is fixedly connected to the empty tube.

[0023] With the above technical solution, by arranging the empty tube in cooperation with the piston block, when gas is blown into the transmission tube, the piston block can be moved by pushing the sliding rod to slide inside the empty tube, and the internal gas is blown into the transmission tube to facilitate providing the power for cutting, and the arranged pulling spring can pull the piston block to reset when the person stops pushing the sliding rod after cutting is completed.

[0024] The present invention is further configured such that: an inclined frame is connected to the outer side height of the upper opening clamp, a guide rail is fixedly connected to the bottom of the inclined frame, a slider is slidably connected to the inner side of the guide rail, and the bottom of the slider is rotatably connected to the top of the threaded rod.

[0025] With the above technical solution, by arranging the inclined frame in cooperation with the guide rail, when the threaded rod moves along the outer hoop, the slider will be pushed or pulled to move, and while the slider slides inside the guide rail, it will drag or push the inclined frame and the upper opening clamp connected thereto to open or close along the rotating pin.

[0026] Compared with the prior art, the present invention provides an obstetrics and gynecology cervical sampling device, which has the following beneficial effects: The obstetrics and gynecology cervical sampling device is equipped with an upper opening clamp and a lower opening clamp as a vaginal auxiliary dilation structure during sampling. The upper opening clamp can rotate along the rotating pin to facilitate the opening of the upper and lower opening clamps for vaginal dilation. The upper and lower opening clamps will contact the vaginal inner wall through a contact sac made of flexible material to improve the degree of fit with the vaginal inner wall and reduce irritation. The sampling tube is connected to the lower opening clamp. After the positions of the upper and lower opening clamps are relatively fixed, it can provide certain auxiliary support for the sampling tube. When a person is sampling, holding the sampling tube and moving it is not likely to shake, etc., to reduce the possibility of sampling position deviation. During the sampling process, hold the position of the extension section and extend it inward along the lower opening clamp until the collection tube contacts the sampling position. Subsequently, the angle of the sampling tube can be adjusted to fit the sampling position. The inspection position will be pressed against the shrinkage mask of the truncation mechanism and recessed partially. The air pump extracts gas to create negative pressure at the left opening position of the collection tube. At this time, the inspection position is further sucked into the collection tube. At this time, the sampling position can be observed. If it is not the position to be sampled, the air pump extraction can be stopped and the position can be changed. If the sampling position is determined, gas can be injected into the transmission tube. The gas fills the flat cavity and pushes the piston sheet and the blade to press down along the flat cavity, cutting off the sampled part and making it approach the air pump under the influence of the air flow. After being intercepted by the interception net plate, it will fall into the bottom tube. This can not only avoid sampling errors that may be caused by directly shearing tissues but also ensure that the tissue sizes obtained each time are consistent. After that, the structure can be taken out, and the tissue can be taken out from the bottom of the collection tube for inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1-9 , a cervical sampling device for obstetrics and gynecology, including an upper opening pliers 1 and a lower opening pliers 2. The upper opening pliers 1 are arranged at the top of the lower opening pliers 2. The outer side of the upper opening pliers 1 is rotatably connected with a rotating pin 3, and the inner side of the lower opening pliers 2 is rotatably connected with the rotating pin 3. Contact capsules 4 are arranged on the inner sides of both the upper opening pliers 1 and the lower opening pliers 2. A sampling tube 5 is arranged between the upper opening pliers 1 and the lower opening pliers 2; The sampling tube 5 includes an integrally formed collection tube 501 and a bottom tube 502. The collection tube 501 is arranged at the top of the bottom tube 502. An integrally formed extension section 503 is arranged on the right side of the bottom tube 502. An air pump 504 is installed inside the collection tube 501. The top of the air pump 504 is arranged inside the collection tube 501. An intercepting net plate 505 is fixedly connected inside the collection tube 501. A truncating mechanism 506 is arranged inside the collection tube 501; The truncation mechanism 506 includes a reduced-diameter mask 506a. A flat cavity 506b is fixedly connected to the top inside the sampling tube 501. A piston piece 506c is slidably connected to the inside of the flat cavity 506b. A blade 506d is fixedly connected to the bottom of the piston piece 506c. The bottom of the blade 506d penetrates through the reduced-diameter mask 506a and is movably connected to the reduced-diameter mask 506a. A integrally formed guiding cover 506e is provided on the right side of the reduced-diameter mask 506a. A transmission tube 506f is fixedly connected to the top on the left side of the flat cavity 506b. One side of the transmission tube 506f away from the flat cavity 506b penetrates through the bottom of the bottom tube 502 and extends out from the inside of the extension section 503. By connecting the sampling tube 5 to the lower opening clamp 2, after the positions of the upper opening clamp 1 and the lower opening clamp 2 are relatively fixed, it can play a certain auxiliary supporting role for the sampling tube 5. When a person takes a sample and holds the sampling tube 5 to move, it is not easy to shake, etc., so as to reduce the possibility of sampling position deviation. During the sampling process, hold the position of the extension section 503 and extend it inward along the lower opening clamp 2 until the sampling tube 501 contacts the sampling position. Then, the angle of the sampling tube 5 can be adjusted to fit the sampling position. The inspection position will be pressed and fit the reduced-diameter mask 506a of the truncation mechanism 506 and sink in a part. The air pump 504 extracts gas to make the left opening position of the sampling tube 501 in negative pressure. At this time, the inspection position is further sucked into the sampling tube 501. At this time, the sampling position can be observed. If it is not the position to be sampled, the air pump 504 extraction can be stopped and the position can be changed. If the sampling position is determined, gas can be blown into the inside of the transmission tube 506f. The gas is filled into the flat cavity 506b and pushes the piston piece 506c and the blade 506d to press down along the flat cavity 506b, cutting off the sampled part and making it close to the air pump 504 under the influence of the air flow. After being intercepted by the interception net plate 505, it will fall into the bottom tube 502. This can not only avoid the sampling error that may be caused by directly shearing the tissue, but also ensure that the tissue size obtained each time is consistent. After that, the structure can be taken out, and the tissue can be taken out from the bottom of the sampling tube 501 for inspection.

[0031] Among them, a narrow frame 8 is fixedly connected to the bottom inside the lower opening pliers 2. A sliding sleeve 9 is slidably connected to the outside of the narrow frame 8. The top of the sliding sleeve 9 is movably connected to the sampling tube 5. By setting the narrow frame 8 in cooperation with the sliding sleeve 9, it is convenient to horizontally move the sampling tube 5 along the lower opening pliers 2 and limit the moving path of the sampling tube 5 to avoid large-angle inclination or rotation, and assist in supporting the sampling tube 5. A sliding ball 10 is fixedly connected to the top of the sliding sleeve 9. A ball joint 11 is slidably connected to the inside of the sliding ball 10. The outside of the collecting tube 501 and the bottom tube 502 are both fixedly connected to the ball joint 11. By setting the sliding ball 10 in cooperation with the ball joint 11, when the person holds the extension section 503 and needs to adjust the sampling position, the ball joint 11 connected to the collecting tube 501 and the bottom tube 502 will slide inside the sliding ball 10, making the structure move more flexibly and making the structure more stable when adjusting the position. A sample groove is provided at the top of the bottom tube 502. Two isolating sheets 15 are fixedly connected to the inside of the bottom tube 502. The outside of the transmission tube 506f penetrates through the isolating sheet 15 and is fixedly connected to the isolating sheet 15. A supplementary light is fixedly connected to the left side of the bottom tube 502. By setting the isolating sheet 15, the airtightness of the structure can be improved, and at the same time, the falling sample tissue can be protected and temporarily stored and limited. The provided supplementary light can facilitate providing a certain amount of illumination for observing the cervical position during sampling. A narrow groove is provided at the bottom of the bottom tube 502. A push piece 16 is slidably connected to the inside of the narrow groove. The right side of the push piece 16 is fixedly connected to a return spring 17. The right side of the return spring 17 is fixedly connected to the right side inside the narrow groove. By setting the push piece 16 at the bottom of the bottom tube 502, the sample tissue will be picked up when it falls. When the sample tissue needs to be taken out, the push piece 16 can be slid along the narrow groove to expose the internal space of the bottom tube 502. At this time, the sample tissue will fall. The provided return spring 17 can deform when the push piece 16 is moved and reset when the person stops pushing to reset the structure. An empty tube 18 is fixedly connected to the right side of the transmission tube 506f. A piston block 19 is slidably connected to the inside of the empty tube 18. The bottom of the piston block 19 is fixedly connected to a sliding rod 20. The outside of the sliding rod 20 is slidably connected to the empty tube 18. The bottom of the piston block 19 is fixedly connected to a tension spring 21. The bottom of the tension spring 21 is fixedly connected to the empty tube 18. By setting the empty tube 18 in cooperation with the piston block 19, when blowing gas into the transmission tube 506f, the piston block 19 can be moved by pushing the sliding rod 20 to slide inside the empty tube 18, and the internal gas can be blown into the transmission tube 506f to facilitate providing the power for cutting. The provided tension spring 21 can pull the piston block 19 to reset when the person stops pushing the sliding rod 20 after cutting is completed.

[0032] Working principle of this embodiment: when taking samples, the personnel hold the sampling tube 5 and move it. The narrow frame 8 cooperates with the sliding sleeve 9 to facilitate the horizontal movement of the sampling tube 5 along the lower opening clamp 2, and the moving path of the sampling tube 5 is limited, so that it is not easy to shake. When the personnel hold the extension section 503 and need to adjust the sampling position, the ball joint 11 connected with the collection tube 501 and the bottom tube 502 will slide in the sliding ball 10 for auxiliary support. During the sampling process, the sampling tube 5 is inserted into the lower opening clamp 2 until the collection tube 501 contacts the sampling position. Then, the angle of the sampling tube 5 can be adjusted to fit the sampling position. The inspection position is compressed to fit the shrink cover 506a of the cut-off mechanism 506. , and a part of it is recessed, the air pump 504 draws gas to make the left opening position of the collection tube 501 negative pressure, at this time the inspection position is further sucked into the collection tube 501, and the piston block 19 is moved by pushing the slide rod 20 to make it slide inside the empty tube 18, and the internal gas is blown into the transmission tube 506f to fill the gas into the flat cavity 506b, and the piston plate 506c and the blade 506d are pushed down along the flat cavity 506b to cut off the sampling part, and make it close to the air pump 504 under the influence of the airflow, and after being intercepted by the interception mesh plate 505, it will fall into the bottom tube 502, and the push piece 16 is slid along the narrow groove to expose the internal space of the bottom tube 502, and the sample tissue will fall.

[0033] Example 2: Reference Figures 1-7 A gynecological cervical sampling device also includes a contact capsule 4, wherein the contact capsule 4 includes a silicone outer layer 401, a rubber inner layer 402 is provided inside the silicone outer layer 401, a heating medium is filled inside the rubber inner layer 402, a heat insulation cotton filling layer 403 is provided between the silicone outer layer 401 and the rubber inner layer 402, and a heating wire 404 is installed inside the rubber inner layer 402; The upper opening forceps 1 cooperate with the lower opening forceps 2 as an auxiliary vaginal expansion structure during sampling. The upper opening forceps 1 can rotate along the rotating pin 3 to open the upper opening forceps 1 and the lower opening forceps 2 for intravaginal expansion, and the upper opening forceps 1 and the lower opening forceps 2 will contact the inner wall of the vagina through the contact bag 4 made of flexible material to improve the fit with the inner wall of the vagina and reduce irritation. By setting the softer silicone outer layer 401 in direct contact with the inner wall of the vagina, a certain deformation can occur when force is applied. The rubber inner layer 402 has a harder texture, which can not only withstand high temperatures to a certain extent, but also have a good storage effect on liquid media. Before sampling, the heating wire 404 can facilitate preheating of the heating medium to make the structural temperature close to the body temperature of the subject, further reducing discomfort.

[0034] Among them, the inner sides of the upper opening clamp 1 and the lower opening clamp 2 are fixedly connected with an assembly sheet 6, and the inner side of the assembly sheet 6 is provided with a rivet pin 7, and the outer side of the rivet pin 7 penetrates the silicone outer layer 401 and the rubber inner layer 402 and is bonded to the rubber inner layer 402 by waterproof glue. By setting the assembly sheet 6 and cooperating with the rivet pin 7, it is convenient to firmly connect the contact capsule 4 and the upper opening clamp 1 or the lower opening clamp 2, and the leakage at the connection can be reduced by waterproof glue bonding. The bottom of the right side of the lower opening clamp 2 is fixedly connected with the external body part 12, and the outer side of the external body part 12 is fixedly connected with the outer hoop 13. The inner side of the outer hoop 13 is threadedly connected with a threaded rod 14, and the top of the threaded rod 14 is movably connected to the upper opening clamp 1. By setting the external body part 12, the right sides of the lower opening clamp 2 and the upper opening clamp 1 are limited outside the body of the person during sampling inspection to avoid excessive penetration and difficulty in removal. At the same time, it is convenient for personnel to operate or observe the internal structure on the right side of the upper opening pliers 1 and the lower opening pliers 2. The outer hoop 13 cooperates with the threaded rod 14 to transmit the structure. When the threaded rod 14 is rotated along the outer hoop 13, the right side of the upper opening pliers 1 will be pulled to rotate downward along the rotating pin 3 and open relative to the lower opening pliers 2. The outer height of the upper opening pliers 1 is connected with a tilting frame 22, and the bottom of the tilting frame 22 is fixedly connected with a guide rail 23, and the inner side of the guide rail 23 is slidably connected with a slider 24, and the bottom of the slider 24 is rotatably connected to the top of the threaded rod 14. By setting the tilting frame 22 to cooperate with the guide rail 23, when the threaded rod 14 is displaced along the outer hoop 13, the slider 24 will be pushed and pulled to move, and the slider 24 will drag or push the tilting frame 22 and the upper opening pliers 1 connected thereto along the rotating pin 3 to open or close while sliding on the inner side of the guide rail 23.

[0035] The working principle of this embodiment is as follows: when in use, the upper opening forceps 1 and the lower opening forceps 2 can be inserted into the inside of the subject, and the threaded rod 14 can be rotated inside the outer hoop 13. The threaded rod 14 is displaced along the outer hoop 13 and will pull the slider 24 to move. While the slider 24 slides on the inner side of the guide rail 23, it will drag the tilting frame 22 and the upper opening forceps 1 connected thereto to open along the rotating pin 3 to expand the vagina. The upper opening forceps 1 and the lower opening forceps 2 will contact the inner wall of the vagina through the contact bag 4 made of flexible material to improve the fit with the inner wall of the vagina and reduce irritation. By setting the softer silicone outer layer 401 in direct contact with the inner wall of the vagina, a certain deformation can occur when subjected to force. The rubber inner layer 402 has a harder texture, which can not only withstand high temperature to a certain extent, but also have a good storage effect on the liquid medium. Before sampling, the heating wire 404 can be used to preheat the heating medium so that the structural temperature is close to the body temperature of the subject.
