Description

Technical Field

[0001] The present invention relates to the technical field of gynecological examination sampling equipment, and in particular to a gynecological examination and sampling equipment that can replace a vaginal speculum. Background Art

[0002] Gynecological examination is an important part of female reproductive health management. Among them, the vaginal speculum is widely used to dilate the vaginal wall for doctors to observe and sample. Clinically, corresponding gynecological examinations must be carried out to prevent and treat vaginal and cervical diseases, including taking vaginal discharge tests at the vagina and fornix with a vaginal speculum, and regularly performing cervical cancer screenings. At present, the vaginal speculum is one of the essential diagnosis and treatment tools in gynecological examinations. Relying solely on the doctor wearing medical gloves and using the touch of 1-2 fingers, although the general situation inside the vagina can be understood, the conditions of the vagina and cervix cannot be comprehensively understood. The vaginal speculum must be inserted into the vagina, and the speculum is gradually dilated and gently rotated when entering the vagina to see the upper, lower, left, and right of the vaginal wall. However, the traditional vaginal speculum has many deficiencies in the use process. For example, during the examination using the vaginal speculum, patients often feel fear, tension, and pain, especially for nulliparous and postmenopausal women. In addition, its structure is relatively fixed and difficult to adjust flexibly, which may cause discomfort to patients. Moreover, during vaginal sampling, the traditional method usually relies on manual sampling with cotton swabs or scraping plates, which is not only complicated in operation but also difficult to ensure the accuracy and sufficiency of sampling, affecting the pathological analysis results.

[0003] In recent years, with the development of medical technology, gynecological examination equipment has gradually developed towards the direction of intelligence and precision. Fiber optic endoscopes have been applied in the field of medical imaging. However, how to combine it with a sampling mechanism to achieve the integration of examination and sampling is still the research focus of current technology. In addition, most of the existing sampling equipment uses a fixed-angle sampling method, and the sampling head angle cannot be adjusted flexibly, resulting in difficulties in sampling specific parts such as the side wall, affecting the comprehensiveness of clinical diagnosis.

[0004] Therefore, we provide a device that can replace the traditional vaginal speculum and integrate the functions of endoscope examination and efficient sampling, which is a gynecological examination and sampling equipment that can replace the vaginal speculum and improve the efficiency and accuracy of gynecological examinations. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a gynecological examination and sampling equipment that can replace a vaginal speculum.

[0006] The object of the present invention is achieved as follows: A gynecological examination and sampling device that can replace a vaginal speculum, including a vaginal dilator tube and an endoscope mechanism. Earrings are provided on both the left and right sides of the upper end of the vaginal dilator tube. A sampling mechanism is disposed in the vaginal dilator tube so as to be movable up and down and withdrawn. The sampling mechanism includes a sampling head and a lifting rod mechanism. The sampling head is located in the vaginal dilator tube so as to be movable up and down, and the sampling head can rotate around the axis diameter of the vaginal dilator tube within the vaginal dilator tube. The upper end of the sampling head is detachably connected to the lifting rod mechanism.

[0007] Further, the lifting rod mechanism includes a lifting rod that is located in the vaginal dilator tube so as to be movable up and down. The lower end of the lifting rod is connected to the sampling head. A baffle is provided on the lifting rod. A retaining ring is fixedly disposed in the vaginal dilator tube. The baffle is located in the vaginal dilator tube above the retaining ring so as to be movable up and down. The lifting rod penetrates through the baffle so as to be movable up and down. A top rod is provided at the upper end of the lifting rod. A first spring is sleeved on the lifting rod, and the upper and lower ends of the first spring are respectively connected to the baffle and the lower end face of the top rod.

[0008] Further, a connecting mechanism is provided between the sampling head and the lifting rod mechanism to connect the sampling head and the lifting rod mechanism. The connecting mechanism includes a connecting seat. The upper end of the connecting seat is connected to the lifting rod mechanism. Two symmetrically distributed and laterally movable pins are provided in the connecting seat. The outer end of the rear side of the pin is a slope structure inclined downward to the middle. The upper end of the sampling head is connected with a connecting plate. Two clamping plates are symmetrically provided on the upper left and right sides of the upper part of the front side of the connecting plate. The upper part of the inner side of the clamping plate is a slope structure inclined downward to the middle. The clamping plates are clamped and limited by the pins.

[0009] Further, two limiting plates are symmetrically provided on the connecting plate between the two clamping plates. The gap between the two limiting plates is a clamping groove. A movable plate is disposed in the connecting seat between the two pins so as to be movable left and right. The length of the movable plate is equal to the length of the clamping groove.

[0010] Further, the upper end of the middle part of the connecting seat is connected with a first connecting rod. The upper end of the first connecting rod is rotatably connected to the lower end of the lifting rod mechanism. Two second connecting rods are symmetrically and fixedly provided on the upper surface of the connecting seat respectively. A pressing rod is connected to the upper part of the second connecting rod. The lower end of the pressing rod is connected to the second connecting rod. A sliding groove is provided in the middle of the second connecting rod. A pressing rod groove is transversely provided in the middle of the second connecting rod. The lower end of the pressing rod is located in the pressing rod groove so as to be movable up and down and rotatable. A rotating shaft is provided at the lower end of the pressing rod. The rotating shaft is located in the sliding groove so as to be movable up and down and rotatable. The upper part of the pressing rod penetrates through the baffle and a button so as to be movable up and down. The sliding groove of the left second connecting rod penetrates through the left side surface of the second connecting rod outward. The lower part of the lifting rod is a bent structure, and the rotation connection shaft between the first connecting rod and the lifting rod mechanism is parallel to the rotation connection shaft at the lowermost end of the second connecting rod and the pressing rod, and the distances from the sampling head are equal.

[0011] Further, a pressing rod is movably arranged inside the lower part of the second connecting rod. The lower end of the pressing rod movably penetrates through the inside of the connecting seat. The inner side of the lower end of the pressing rod is of an inclined surface structure, and the upper part of the outer side of the pin is of an inclined surface structure. The inclined surface structure at the lower end of the pressing rod is fitted with the inclined surface structure on the outer side of the pin. A guiding rod is fixedly arranged at the upper end of the pressing rod. The guiding rod movably penetrates through the bottom of the pressing rod groove of the second connecting rod. A pressing plate is arranged at the upper end of the guiding rod. A third spring is sleeved on the outer side of the guiding rod, and the upper and lower ends of the third spring are respectively in contact with the pressing plate and the bottom of the pressing rod groove.

[0012] The endoscope mechanism includes a fiber optic endoscope main rod, a fiber optic endoscope body, and a data cable. The fiber optic endoscope main rod is connected to the fiber optic endoscope body. A data cable is connected to the rear end of the fiber optic endoscope body. The data cable transmits the data obtained by the endoscope mechanism to the rear end for processing and recognition. A lighting mechanism is arranged at the front end of the fiber optic endoscope main rod to illuminate the inside of the human body. The front end of the fiber optic endoscope main rod is equipped with a camera mechanism to cooperate with the fiber optic endoscope body to photograph the inside of the human body. The photographed data is transmitted to the rear end through the data cable for processing and recognition. The fiber optic endoscope main rod and the fiber optic endoscope body are prior arts and will not be described in technical details. As long as they can achieve the above functions.

[0013] When the present invention is used, the vaginal dilator is placed in the vagina, and then the inside of the vagina is photographed through the endoscope mechanism. The part to be sampled is determined through the recognition at the rear end. The inner end of the vaginal dilator is moved to the part to be sampled in cooperation with the vaginal dilator. The endoscope mechanism is taken out, and the sampling mechanism is inserted into the vaginal dilator to sample the sampling part.

[0014] When the sampling mechanism samples, the sampling mechanism is placed in the vaginal dilator. At this time, the sampling head is located at the lower end inside the vaginal dilator. The outer side of the baffle is in contact with and moves along the inner side of the vaginal dilator, and the outer side of the lower part of the button is in contact with and moves up and down along the inner side of the vaginal dilator. At this time, the baffle is limited by the retaining ring to prevent the whole sampling mechanism from continuing to move downward along the vaginal dilator. The sampling head can movably penetrate through the retaining ring. At this time, the lower end of the sampling head is located at the position of the lower port of the vaginal dilator. When sampling the inside of the vagina, the button is pressed downward. The button drives the ejector rod to move downward, and at the same time drives the lifting rod to move downward, thereby driving the sampling head to move downward, so that the sampling head is in contact with and fits the sampling part. In order to ensure accurate sampling of the sampling part, the sampling head needs to be rotated to ensure successful sampling of the sampling part and avoid sampling errors caused by the limited contact area of the sampling head. When rotating and sampling the sampling head, by rotating the button, since the button is provided with protrusions to increase the friction with the hand, it is convenient to rotate the button to rotate the sampling head. When the button rotates, since the button, the ejector rod, and the lifting rod are fixedly connected, and the lifting rod is connected to the sampling head, the sampling head will be driven to rotate during rotation, realizing precise sampling operation.

[0015] In addition, when it is necessary to sample the vaginal side wall, a simple downward-facing sampling head may cause inconvenience in sampling or poor sampling effect. Therefore, the present application is provided with a rotatable sampling head. When it is necessary to tilt the sampling head to sample the vaginal side wall, by pressing down the lever at the right end, the lower end of the lever squeezes the second connecting rod downward, driving the connecting seat to rotate downward. In order to avoid rotational interference, a sliding groove is provided to ensure that the rotating shaft can move up and down. At the same time, the sliding groove on the left side of the second connecting rod extends through the left side surface of the second connecting rod. When the connecting seat rotates, the lever on the left side will disengage from the sliding groove of the second connecting rod, realizing the inclination of the connecting seat, and then driving the adjustment of the inclination angle of the sampling head; after the sampling head is tilted, the sampling operation of the vaginal side wall can be realized.

[0016] After sampling, reset the inclination angle of the sampling head. Releasing the button can drive the sampling head to retract into the vaginal dilator under the reset action of the first spring; then take out the entire sampling mechanism, and remove the sampling head on the sampling mechanism. When removing the sampling head, in order to avoid direct contact of the human hand with the sampling head causing contamination of the sample and to increase the convenience of using the sampling mechanism, a connecting mechanism is provided, which can facilitate the disassembly of the sampling head and avoid direct hand contact with the sampling head; that is, when removing the sampling head, the sampling head is reset, that is, at this time, the lower ends of both levers are located in the sliding groove. At the same time, press down the levers, so that the lower ends of both levers simultaneously squeeze the corresponding pressure plates. At this time, the guide rod moves downward, and the third spring is compressed. When the guide rod moves downward, it drives the extrusion rod to move downward. The inclined surface structure at the lower end of the extrusion rod squeezes the inclined surface structure on the outer side of the pin. During the extrusion process, the pin is driven to move towards the middle position of the connecting seat. When the extrusion rod moves to the lowest end, at this time, the outer end of the inclined surface at the outer end of the rear side of the pin disengages from the limiting action of the lower surface of the clamping plate, and the length of the rear part of the pin is located below the disengaging groove. The pin disengages from the limiting of the connecting plate through the disengaging groove, and at this time, the inner end of the pin cooperates with the moving plate to squeeze the second spring. At this time, the second spring is completely located in the spring groove, and the inner end of the pin is in contact with the end surface of the moving plate to ensure that the moving plate is located directly below the clamping groove to release the limiting action on the limiting plate. At this time, the sampling head can be naturally detached from the connecting structure by the self-gravity of the sampling head, or the sampling head can also be removed by pulling down the sampling head with an external force, or a spring mechanism is provided at the upper end of the connecting plate to realize the detachment of the sampling head from the connecting structure by the elastic force of the spring structure. The above specific structures or methods are not limited technically, as long as the sampling head can be detached from the connecting mechanism.

[0017] When installing the sampling head with the above-mentioned connecting mechanism, one only needs to hold the sampling head and align the connecting plate at the upper end of the sampling head with the connecting groove provided at the lower end of the connecting seat (the connecting groove and the connecting plate fit each other). When pushing the connecting plate into the connecting groove, the inclined surface structure at the outer end of the rear side of the latch pin is subjected to the acting force of the inclined surface structure of the clamping plate, causing the latch pin to move outwards. When the connecting plate is completely located within the connecting groove, the inclined surface of the latch pin disengages from the limiting effect of the inclined surface of the clamping plate, and the latch pin resets, realizing the limiting and clamping of the lower end surface of the clamping plate, and further realizing the limiting effect on the connecting plate and the connection effect on the sampling head.

[0018] During the sampling process of the sampling head, it may cause the extrusion of one side of the pressure rod on the second connecting rod (causing the guide rod to move downwards and the extrusion rod to move downwards, and further causing the latch pin to move inwards, so that one side of the latch pin disengages from the limiting effect on the connecting plate, causing the sampling head to disengage from the sampling mechanism). For example, when adjusting the inclination angle of the sampling head, in order to prevent one side of the pressure rod from moving downwards and causing one side of the latch pin to disengage from the limiting effect on the clamping plate, resulting in only one side of the latch pin having a limiting effect and there being a certain risk of the sampling head disengaging, a movable plate that can move left and right is provided in cooperation with the two springs II on both sides. (That is, when one side of the clamping plate moves towards the middle, because) and when both sides of the latch pins move downwards to the lowest position, the movable plate will be directly below the disengaging groove. Therefore, no matter which side of the latch pin moves downwards to the lowest position, the movable plate will limit one side of the limiting plate, cooperating with the limiting effect of the latch pin and the clamping plate on the other side, that is, forming two-position limiting effects can ensure that the sampling head will not disengage from the sampling mechanism and ensure the service life of the connecting mechanism (the connection of a single point to the sampling head will cause instability after long-term use, and problems such as wear and sampling head detachment are likely to occur).

[0019] Beneficial effects:

[0020] Convenient expansion and fixation: Ear rings are provided on both sides of the vaginal speculum, facilitating grasping and operation, improving the stability of use, and at the same time enhancing the doctor's control force, making the examination smoother.

[0021] Precise sampling mechanism: The sampling mechanism can move up and down and can rotate around the axis diameter of the vaginal speculum, enabling the sampling head to accurately align with the target part, improving the sampling accuracy and reducing errors.

[0022] Automatic reset function: The sampling head is connected to the lifting rod mechanism and is equipped with a spring I, which can achieve automatic reset, avoiding errors caused by manual adjustment and improving the sampling efficiency at the same time.

[0023] Convenient rotation operation: A convex structure is provided on the outside of the button to enhance the friction force, making rotation easier, thus facilitating the adjustment of the angle of the sampling head and improving the convenience and accuracy of the operation.

[0024] Multi-angle sampling: The sampling head can be adjusted in angle through the lever mechanism to meet different sampling requirements. Especially for parts such as the side wall of the vagina that are difficult to sample directly, it improves the comprehensiveness of sampling.

[0025] Interference-free structural design: Through the reasonable layout of the first connecting rod and the second connecting rod, it avoids structural interference when the sampling head rotates, improving the stability and durability of the equipment.

[0026] Efficient sampling head disassembly method: Adopting the limit clamping structure of the pin and the clamping plate enables the sampling head to be quickly disassembled, reducing direct contact by medical staff, lowering the risk of contamination, and improving the reuse rate of the equipment.

[0027] Stable connection mechanism: The moving plate cooperates with the bilateral pins to ensure that the sampling head is stable and does not fall off during the sampling process. At the same time, it avoids loosening of the connection components caused by long-term use, improving the reliability and service life of the equipment.

[0028] Integrated endoscope examination function: The fiber endoscope can capture and transmit data in real time, assisting doctors in accurately positioning the sampling location, improving the examination efficiency, reducing unnecessary sampling, and enhancing patient comfort.

[0029] Through precise structural design, the present invention realizes the integration of examination and sampling, avoids the discomfort of traditional vaginal speculums, improves the accuracy and convenience of sampling, and is applicable to various gynecological examination scenarios.

A lighting mechanism 25 is provided at the front end of the fiber optic endoscope main rod to illuminate the interior of the human body. The interior of the human body is photographed through the eyepiece 29 at the front end of the fiber optic endoscope main rod 26 in cooperation with the fiber optic endoscope main body 27. The photographed data is transmitted to the rear end through the data cable 28 for processing and recognition. The lighting mechanism 25, the fiber optic endoscope main rod 26, the fiber optic endoscope main body 27, and the eyepiece 29 are prior arts and will not be described in detail technically. As long as the above functions can be achieved.

[0050] When the present invention is used, the vaginal speculum 1 is placed in the vagina, and then the interior thereof is photographed through the endoscope mechanism. The part that needs to be sampled is determined through the recognition at the rear end. The inner end of the vaginal speculum 1 is moved to the part that needs to be sampled in cooperation with the vaginal speculum 1. The endoscope mechanism is taken out, and the sampling mechanism is inserted into the vaginal speculum 1 to sample the sampling part thereof.

[0051] When the sampling mechanism samples, the sampling mechanism is placed in the vaginal speculum 1. At this time, the sampling head 11 is located at the lower end inside the vaginal speculum 1. The outer side surface of the baffle 8 fits and moves with the inner side surface of the vaginal speculum 1, and the outer side surface of the lower part of the button 3 fits and moves up and down with the inner side surface of the vaginal speculum 1. At this time, the baffle 8 is limited by the retaining ring 9 to prevent the whole sampling mechanism from continuing to move downward along the vaginal speculum 1. The sampling head 11 can move up and down through the retaining ring 9. At this time, the lower end of the sampling head 11 is located at the position of the lower port of the vaginal speculum 1. When it is necessary to sample the interior of the vagina, the button 3 is pressed downward. The button 3 drives the ejector rod 6 to move downward, and at the same time drives the lifting rod 10 to move downward, thereby driving the sampling head 11 to move downward, so that the sampling head 11 contacts and fits with the sampling part. In order to ensure accurate sampling of the sampling part, the sampling head 11 needs to be rotated, which can ensure successful sampling of the sampling part and avoid sampling errors caused by the limited contact area of the sampling head 11. When rotating and sampling the sampling head 11, by rotating the button 3, since the button 3 is provided with a protrusion 4 to increase the friction between it and the hand, it is convenient to rotate the button 3 to realize the rotation of the sampling head 11. When the button 3 rotates, since the button 3, the ejector rod 6, and the lifting rod 10 are fixedly connected, and the lifting rod 10 is connected to the sampling head 11, the sampling head 11 will be driven to rotate during rotation, realizing accurate sampling operation.

[0052] In addition, when it is necessary to sample the side wall of the vagina, the simple downward-facing sampling head 11 may cause inconvenience in sampling or poor sampling effect. Therefore, the present application is provided with a rotatable sampling head 11. When it is necessary to take a sample from the side wall of the vagina at an inclined angle of the sampling head 11, by pressing down the lever 5 at the right end, the lower end of the lever 5 squeezes the second connecting rod 14 downward, driving the connecting seat 12 to rotate downward. In order to avoid rotational interference, a chute is provided to ensure that the rotating shaft 16 can move up and down. At the same time, the chute on the left side of the second connecting rod 14 penetrates through the left side surface of the second connecting rod 14 outward. When the connecting seat 12 rotates, the lever 5 on the left side will disengage from the chute of the second connecting rod 14, realizing the inclination of the connecting seat 12, and then driving the adjustment of the inclination angle of the sampling head 11; after the sampling head 11 is inclined, the sampling operation of the side wall of the vagina can be realized.

[0053] After sampling, reset the inclination angle of the sampling head 11. Loosing the button 3 can drive the sampling head 11 to retract into the vaginal dilator 1 under the reset action of the first spring 7; then take out the entire sampling mechanism, and remove the sampling head 11 on the sampling mechanism. When removing the sampling head 11, in order to avoid direct contact of the human hand with the sampling head 11 causing contamination of the sample, and at the same time increasing the convenience of using the sampling mechanism, a connecting mechanism is provided, which can facilitate the disassembly of the sampling head 11 and avoid direct hand contact with the sampling head 11; that is, when removing the sampling head 11, the sampling head 11 is reset, that is, at this time, the lower ends of the two levers 5 are both located in the chute. At the same time, press down the levers 5, so that the lower ends of the two levers 5 simultaneously squeeze the corresponding pressure plates. At this time, the guide rod 23 moves downward, and the third spring 22 is compressed. When the guide rod 23 moves downward, it drives the extrusion rod 13 to move downward. The inclined surface structure at the lower end of the extrusion rod 13 squeezes the inclined surface structure on the outer side of the pin 20. During the extrusion process, the pin 20 is driven to move towards the middle position of the connecting seat 12. When the extrusion rod 13 moves to the lowest position, at this time, the outer end of the inclined surface at the outer end of the rear side of the pin 20 disengages from the limiting action of the lower surface of the clamping plate 21, and the length of the rear part of the pin 20 is located below the disengaging groove. The pin 20 disengages from the limiting of the connecting plate 24 through the disengaging groove, and at this time, the inner end of the pin 20 cooperates with the moving plate 18 to squeeze the second spring 19. At this time, the second spring 19 is completely located in the spring groove, and the inner end of the pin 20 is in contact with the end surface of the moving plate 18, ensuring that the moving plate 18 is located directly below the clamping groove to release the limiting effect on the limiting plate 17. At this time, due to the self-gravity of the sampling head 11, it can naturally disengage from the connecting structure, or the sampling head 11 can also be removed by pulling down the sampling head 11 with an external force, or a spring mechanism is provided at the upper end of the connecting plate 24 to realize the disengagement of the sampling head 11 from the connecting structure by the elastic force of the spring structure. The above specific structures or methods are not limited technically, as long as the sampling head 11 can be disengaged from the connecting mechanism.

[0054] When installing the sampling head 11, the above-mentioned connecting mechanism only requires holding the sampling head 11 by hand and aligning the connecting plate 24 at the upper end of the sampling head 11 with the connecting groove opened at the lower end of the connecting seat 12 (the connecting groove and the connecting plate 24 fit each other). When pushing the connecting plate 24 into the connecting groove, the inclined surface structure at the outer end of the rear side of the latch 20 is subjected to the acting force of the inclined surface structure of the clamping plate 21, causing the latch 20 to move outwards. When the connecting plate 24 is completely located within the connecting groove, the inclined surface of the latch 20 disengages from the limiting effect of the inclined surface of the clamping plate 21, and the latch 20 resets, realizing the limiting and clamping of the lower end surface of the clamping plate 21, thereby realizing the limiting effect on the connecting plate 24 and the connecting effect on the sampling head 11.

[0055] During the sampling process of the sampling head 11, it may cause the extrusion of the pressure rod 5 on one side against the second connecting rod 14 (causing the guide rod 23 to move downward, the extrusion rod 13 to move downward, and further causing the latch 20 to move inward, so that the latch 20 on one side disengages from the limiting effect on the connecting plate 24, causing the sampling head 11 to disengage from the sampling mechanism). For example, when adjusting the inclination angle of the sampling head 11, in order to prevent the latch 20 on one side from disengaging from the limiting effect on the clamping plate 21 when the pressure rod 5 on one side moves downward, resulting in only one side of the latch 20 having a limiting effect and there being a certain risk of the sampling head 11 disengaging, a movable plate 18 that can move left and right is provided in cooperation with the two springs two 19 on both sides. (That is, when the clamping plate 21 on one side moves towards the middle, because) And when both latches 20 on both sides move downward to the lowest position, the movable plate 18 will be directly below the disengaging groove. Therefore, no matter which side the latch 20 moves downward to the lowest position, the movable plate 18 will limit one side of the limiting plate 17, cooperating with the limiting effect of the latch 20 and the clamping plate 21 on the other side, that is, forming two-position limiting effects can ensure that the sampling head 11 will not disengage from the sampling mechanism and ensure the service life of the connecting mechanism (the connection of a single point to the sampling head 11 will cause instability after long-term use, and problems such as wear and the sampling head 11 falling off are likely to occur).
