Technical Field

[0001] The present invention relates to the technical field of vaginal dilators, in particular to a vaginal dilator for auxiliary cleaning in obstetrics and gynecology. Background Art

[0002] Gynecological inflammation is the most common clinical gynecological disease. Especially in recent years, with the accelerated pace of people's lives and irregular living habits, the incidence of gynecological inflammation has increased year by year. For patients with vaginitis or vaginal adhesions after close-range radiotherapy for cervical cancer, they need to be flushed with medicine in clinical practice. In this process, a dilator is needed. The dilator is an auxiliary tool used by the reproductive department to dilate the vagina. After assisting in stretching the vagina, it is convenient for doctors to perform flushing and gynecological examinations.

[0003] In the existing technology, the vagina is mainly dilated by using a duckbill structure to expand the vagina, and then a flushing tube is inserted to flush the vaginal wall. In conventional operation, when using the dilator, lubricant is applied or the dilator is directly inserted into the vagina. This operation method can easily damage the patient's vaginal wall, and during the dilation process, unilateral expansion is mostly performed in a straight direction, which also increases the patient's discomfort. Summary of the Invention

[0008] In order to improve the adsorption effect, the negative pressure part further includes: negative pressure blades equidistantly distributed on the outer wall of the driving cylinder, the negative pressure blades are arranged between the air intake channel and the exhaust channel; a friction ring surrounding and covering the outer periphery of the negative pressure blades, and a driving component for driving the friction ring to rotate is provided in the operating handle.

[0009] Furthermore, the driving assembly includes a motor fixedly connected to the operating handle, and a driving friction wheel is installed on the output end of the motor, and the driving friction wheel is in contact with the friction ring.

[0010] In order to improve the comfort of patients, preferably, the vibration part includes: a vibration cylinder, the end faces of the vibration cylinder abutting against the driving cylinder are fixedly connected with end face cams, and when the driving cylinder rotates, the vibration cylinder and the driving cylinder approach or move away from each other; two groups of springs, respectively fixedly connected to the end ends of the vibration cylinder and the driving cylinder, and the other end of the spring abuts against the inner wall of the flushing channel.

[0011] In order to improve the stability of operation, further, a damping strip is fixedly connected to the inner wall of the vibration cylinder. When the flushing pipe passes through the inner ring channel of the vibration cylinder, the damping strip forms an interference fit with the outer wall of the flushing pipe.

[0015] Preferably, the abutting column and the positioning block are both made of ferromagnetic materials.

[0016] Compared with the prior art, the present invention provides a vaginal stretching device for auxiliary cleaning in obstetrics and gynecology, which has the following beneficial effects:

[0017] 1. This vaginal dilator for auxiliary cleaning in obstetrics and gynecology can extract odor and excess fluid by generating negative pressure. The exhaust channel can be equipped with a threaded joint on the outer wall of the operating handle to connect to a drainage tube to guide waste fluid to a waste liquid bucket for centralized treatment. Filter cotton such as activated carbon can also be inserted into the suction hole to reduce the risk of odor being inhaled by medical staff when discharged from the exhaust channel, thereby affecting the comfort of medical staff during operation.

[0018] 2. This vaginal dilator for obstetrics and gynecology, used to assist with cleaning, transmits vibrations to the dilator, causing a slight numbing sensation on the skin. This stimulates and activates sensory nerve fibers, such as Aδ and C fibers. This signal is transmitted to the spinal cord and brain, such as the nucleus accumbens or prefrontal cortex, prompting the body to release endorphins, natural analgesics. This can also relieve tension and induce a sense of relaxation, reducing the foreign body sensation and pain during insertion, and partially alleviating the patient's fear.

[0019] 3. This vaginal dilator for auxiliary cleaning in obstetrics and gynecology has two sets of dilator blades with hemispherical ends, which seal the end of the vagina to prevent deep infection. It uses a rotating seat as a fulcrum to expand to both sides synchronously, which can effectively reduce the discomfort of unilateral expansion.

[0020] 4. This vaginal dilator for auxiliary cleaning in obstetrics and gynecology can ensure the support strength and stability of the dilator by covering the supporting ribs of the rubber sheet. After the dilator is opened, the negative pressure holes can be used to absorb the waste liquid and secretions generated during the cleaning process into the negative pressure channel for unified discharge, thereby effectively ensuring the safety of cleaning and preventing waste liquid from infecting and entering the deep part of the vagina. The outer surface of the rubber sheet can also be filled with lubricating liquid to reduce dry friction with the vagina when the dilator is inserted into the vagina, effectively protecting the vagina.

[0021] 5. The vaginal stretching device for auxiliary cleaning in obstetrics and gynecology can change the expansion angle of the stretching piece by adjusting the position of the columnar platform and pushing and rotating the flushing tube during cleaning. On the one hand, it can control the position of the water flow, making it easier for medical staff to choose according to the individual differences of patients. On the other hand, the forced contact method can effectively transmit the vibration of the vibration cylinder to the stretching piece, thereby effectively reducing the patient's discomfort during the flushing process.

[0022] The parts not involved in this device are the same as the existing technology or can be implemented by using existing technology. The present invention avoids damaging the patient's vaginal wall by controlling the expansion part to open at a smaller angle at the deep end than at the external end, thereby improving the patient's comfort and making it convenient for medical staff to observe and judge the condition. Moreover, during expansion, by changing the position of the driving part in the expansion part and the insertion depth of the flushing tube, it can effectively ensure the controllability of the flushing position and give medical staff greater freedom of expansion. In addition, the negative pressure channel is used to extract the waste liquid and secretions generated during the cleaning process, which can further improve the safety of cleaning and the clarity of operation.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] Example:

[0035] Reference Figures 1-8, a vaginal dilator for auxiliary cleaning in obstetrics and gynecology, comprising a grippable cylindrical operating handle 1, the operating end of the operating handle 1 having a rechargeable energy storage battery for providing electrical energy and basic functions such as buttons, an expansion portion at the working end of the operating handle 1, and a cylindrical flushing channel 101 running through the front and back along the axis L of the operating handle 1, the flushing channel 101 being a stepped through hole, the diameter near the working end being larger than the diameter near the operating end, and the diameter of the operating end being slightly larger than the diameter of the flushing tube, usually 3-5 mm larger, in this embodiment, the expansion portion is fixed by a U-shaped bracket 5 fixedly connected to the working end of the operating handle 1, the open end of the U-shaped bracket 5 being fixedly connected to the end surface of the operating handle 1, the expansion portion being mounted on the free end of the bracket 5, and during the expansion process, the expansion is carried out with the free end of the bracket 5 as a fulcrum, so that the vaginal opening can be expanded to a greater extent, while the deep part of the vagina can be expanded to a lesser extent, which is more in line with the structure of the human body, effectively improving the comfort of the patient, and facilitating the doctor to observe the internal organs. The embodiment of the present invention relates to a device for the operation of the expansion portion of the invention. The device comprises a driving cylinder 2, which is installed in the flushing channel 101 and can slide back and forth and rotate around the axis L. The driving cylinder 2 is provided with a negative pressure part. During the rotation of the driving cylinder 2, the negative pressure part can be driven to operate. A negative pressure channel is opened in the operating handle 1, and the negative pressure part is arranged in the negative pressure channel. The expansion portion is provided with an adsorption part connected to the negative pressure channel. In this embodiment, during the operation of the negative pressure part, the negative pressure channel generates negative pressure, so that the adsorption part on the expansion portion works, which can adsorb the cleaning fluid generated during the cleaning process, reduce the flow of the cleaning fluid in the vagina and the natural outflow, thereby avoiding cross infection caused by excess fluid; there is also a vibration part abutting against the driving cylinder 2, which is arranged in the flushing channel 101, wherein the expansion portion is provided with a driving part. When the flushing tube passes through the flushing channel 101 and extends to the expansion portion, the vibration part contacts the flushing tube, and the driving part abuts against the end of the flushing tube, so that the opening range of the expansion portion can be self-adjusted by changing the position of the driving part on the expansion portion and the insertion depth of the flushing tube.

[0036] In the above design, by controlling the expansion part to expand at a smaller angle in the deep part than in the external part, damage to the patient's vaginal wall is avoided, the patient's comfort is improved, and it is convenient for medical staff to observe and judge the condition. Moreover, during expansion, by changing the position of the driving part in the expansion part and the insertion depth of the flushing tube, the flushing position can be effectively controlled, and medical staff can be given greater freedom of expansion. The negative pressure channel is used to extract the waste liquid and secretions generated during the cleaning process, which can further improve the safety of cleaning and the clarity of operation.

[0037] Specifically, the negative pressure channel includes an air intake channel 103 and an air exhaust channel 104 that are interconnected. An air suction hole 102 is also provided in the large-diameter stepped hole of the flushing channel 101, and the air suction hole 102 is connected to the air intake channel 103. In this embodiment, when the medical staff inserts the expansion part into the vagina, the negative pressure generated can be used to extract odor and excess liquid. The exhaust channel 104 can be equipped with a threaded joint at the outer wall of the operating handle 1 to connect the drainage tube and guide the waste liquid to the waste liquid barrel for centralized treatment. In other embodiments, the air suction hole 102 is mainly used to extract odorous gases. Therefore, some filter cotton such as activated carbon can be stuffed into the air suction hole 102 to reduce the odor being inhaled by medical staff when it is discharged from the exhaust channel 104, affecting the comfort of medical staff's operation.

[0038] Specifically, the negative pressure part includes: negative pressure blades 202 equidistantly distributed on the outer wall of the driving cylinder 2 in a circumferential manner, the negative pressure blades 202 are arranged between the air inlet channel 103 and the exhaust channel 104, thereby separating the two. When the negative pressure blades 202 revolve around the axis L, a negative pressure adsorption effect can be generated in the air inlet channel 103, and a positive pressure can be generated in the exhaust channel 104 to discharge odor and waste liquid in a concentrated manner; a friction ring 201 is wrapped around the periphery of the negative pressure blades 202, a motor 8 is fixedly connected to the operating handle 1, and a driving friction wheel 801 is installed at the output end of the motor 8, and the driving friction wheel 801 is in contact with the friction ring 201. In some embodiments, in order to improve the transmission In order to improve the reliability of movement, the friction wheel 801 and the friction ring 201 can be designed as a toothed structure to form tooth meshing. However, since the driving cylinder 2 needs to make left and right and rotational movements, the output shaft of the motor 8 is prismatic, and a prismatic through hole is opened along the axial direction of the driving toothed friction wheel 801. The prismatic output shaft passes through the prismatic through hole, so that when the output shaft rotates, it can drive the toothed friction wheel 801 to rotate without limiting the axial displacement of the toothed friction wheel 801, so that the toothed friction wheel 801 is always meshed with the toothed friction ring 201, driving the negative pressure blade 202 to continuously generate negative pressure in the negative pressure channel, thereby ensuring the continuity of the extraction operation and improving work efficiency.

[0039] Specifically, the vibration part includes: a vibration tube 3, the end faces of the vibration tube 3 and the driving tube 2 are fixedly connected with end face cams 203. When the driving tube 2 rotates, the vibration tube 3 abuts against the two end face cams 203 on the driving tube 2, and the vibration tube 3 and the driving tube 2 move away from each other. When the two end face cams 203 are staggered, the vibration tube 3 and the driving tube 2 move closer to each other, and cooperate with the spring 302 fixedly connected to the end of the vibration tube 3 and the driving tube 2 respectively. Since the other end of the spring 302 abuts against the inner wall of the flushing channel 101, as the driving tube 2 rotates one circle, the vibration tube 3 will impact once. The driving cylinder 2, the vibration force of the impact and the movement of the vibration cylinder 3 can be transmitted to the expansion part through the connecting structure, and can also be transmitted to the driving part and the expansion part through the flushing tube. It can be started before the expansion part is inserted into the vagina. Through the frequency of 50-80Hz, the skin produces a slight numbness, stimulates and activates sensory nerve fibers, such as Aδ and C fibers, and the signal is transmitted to the spinal cord and brain, such as the nucleus accumbens or the prefrontal cortex, to prompt the body to release endorphins, which are natural analgesics. At the same time, it can relieve tension and produce a sense of relaxation, reduce the patient's foreign body sensation and pain during insertion, and partially reduce the patient's fear.

[0040] There are also 4-8 damping strips 301 fixedly connected to the inner wall of the vibration tube 3 at equal intervals in a circle. When the flushing pipe passes through the inner ring channel of the vibration tube 3, the damping strips 301 form an interference fit with the outer wall of the flushing pipe, thereby only covering the flushing pipe, and then effectively transmitting the vibration through the flushing pipe to the expansion part.

[0041] Specifically, the expansion part includes: two groups of expansion pieces 4, and the end of the bracket 5 away from the operating handle 1 is fixedly connected to the rotating seat 501, and the two groups of expansion pieces 4 are rotatably connected to the rotating seat 501. Here, a torsion spring can be installed on the rotating shaft of the rotating seat 501. Its purpose is to cause the two expansion pieces 4 to move closer to each other to form a cylindrical shape in a natural state. When the two groups of expansion pieces 4 are closed, the ends of the two groups of expansion pieces 4 are hemispherical, which closes the end of the vagina and prevents deep infection. When the two groups of expansion pieces 4 are unfolded, while ensuring the hemispherical shape, they are synchronously expanded to both sides with the rotating seat 501 as the fulcrum, which can effectively reduce the discomfort of unilateral expansion; 2-4 pairs of positioning blocks 405 are equidistantly fixedly connected to the inner wall of the expansion piece 4, and the driving part cooperates with the positioning block 405. The expansion piece 4 can be expanded by pushing the positioning block 405 by the driving part.

[0042] Specifically, the expansion piece 4 includes: an annular support rib 401, a guide channel 402 is opened in the support rib 401, and the guide channel 402 is connected to the air inlet channel 103 through a telescopic tube 403. The telescopic tube 403 can pull the two expansion pieces 4 closer to each other to form a cylindrical shape; a medical rubber sheet or a silicone sheet is coated on the support rib 401, and 3-6 negative pressure holes 404 are opened on both side edges of the rubber sheet, and the negative pressure holes 404 are connected to the guide channel 402. The support rib 401 coated with the rubber sheet can not only ensure the support strength and stability of the expansion piece 4, but also can use the negative pressure holes 404 to absorb the waste liquid and secretions generated during the cleaning process into the negative pressure channel for unified discharge after it is stretched, thereby effectively ensuring the safety of cleaning, avoiding waste liquid infection and waste liquid entering deep into the vagina. In other embodiments, the outer surface of the rubber sheet is also provided with a recessed structure, which can be filled with lubricating liquid, thereby reducing dry friction with the vagina when the expansion piece 4 is inserted into the vagina, and effectively protecting the vaginal wall.

[0043] Specifically, the driving part includes: a cylindrical platform 6, a spherical hinge seat 701 is provided on the circumferential surface of the cylindrical platform 6, the spherical hinge seat 701 is fixedly connected to the abutment column 702 through the connecting rod 7, the abutment column 702 abuts on the positioning block 405, and both are ferromagnetic materials, which can effectively adsorb when in contact to prevent falling off; a flushing nozzle 601 is rotatably connected to the end of the cylindrical platform 6, a spherical positioning cavity is provided in the cylindrical platform 6, which is convenient for the abutment of the flushing tube, and the positioning cavity is connected to the flushing nozzle 601, and the liquid flow direction in the flushing nozzle 601 is 30°-75° to the axis L. By adjusting the position of the cylindrical platform 6, the flushing tube is pushed and rotated during cleaning. On the one hand, the expansion angle of the expansion sheet 4 can be changed, thereby controlling the position of the water flushing, which is convenient for medical staff to choose according to the individual differences of the patients. On the other hand, the forced abutment method can effectively transmit the vibration of the vibration tube 3 to the expansion sheet 4, thereby effectively reducing the patient's discomfort during the flushing process.

[0044] In some embodiments, as the end face cam 203 impacts and vibrates, since the driving cylinder 2 and the vibration cylinder 3 are both in a floating state under the action of the spring 302, when the driving cylinder 2 is impacted, it will also suddenly slide back and forth, thereby forming a fluctuating negative pressure flow in the negative pressure channel. This process is transmitted to the negative pressure hole 404, which can cause the negative pressure around it to suddenly increase. This method can prevent the negative pressure hole 404 from being blocked, and can also more forcefully suck in and discharge secretions, further improving the cleaning effect of the vagina.

[0045] In the present invention, when in use, according to the individual differences of the patients and the size of the required expansion, the doctor will abut the abutting column 702 on the appropriate positioning block 405, pass the irrigation tube through the irrigation channel 101 and abut it in the spherical positioning cavity of the cylindrical platform 6, and abut it with the irrigation nozzle 601. In this process, the interference fit between the vibration cylinder 3 and the irrigation tube is close to a rigid connection. Then, lubricating oil is applied to the surface of the expansion piece 4, and the motor 8 is started to drive the driving cylinder 2 to rotate rapidly. During the rotation of the driving cylinder 2, it drives the vibration cylinder 3 along the axis L through the end face cam 203 to impact and vibrate with the driving cylinder 2, and transmit the vibration to the expansion piece 4 through the irrigation tube. Then, the patient takes the lithotomy position, exposes the vulva, and after disinfection, slowly inserts the unexpanded expansion piece 4 into the vagina. In this process, the suction hole 102 can absorb the odor in the vagina and purify it and discharge it, and the negative pressure hole 404 can absorb the inside of the vagina. The secretions and excess lubricating fluid squeezed out are uniformly discharged through the negative pressure channel. During the advancement, the vibrating expansion piece 4 can reduce the patient's foreign body sensation and discomfort, enter the flushing, push the flushing tube, and as the columnar platform 6 moves, it can gradually move the connecting rod 7 to a vertical state, thereby making the two expansion pieces 4 expand symmetrically in the vagina, making the expansion of the vagina conical, that is, the entrance is large and the interior gradually becomes smaller, which is convenient for medical staff to observe the internal situation of the vagina. After determining the flushing plan, the cleaning liquid is sent to the flushing nozzle 601 through the flushing tube, and the flushing nozzle 601 can be rotated to change the flushing position. During the flushing process, the negative pressure hole 404 can draw the waste liquid through the negative pressure channel and discharge it uniformly. After the flushing is completed, the expansion piece 4 is released and pulled out synchronously with the flushing tube, and then the flushing tube is removed, and the entire device is immersed in disinfectant or clean water. The internal channel is flushed by negative pressure to ensure safe and hygienic use.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
