Description

Technical Field

[0001] The present invention relates to the technical field of vaginal speculums, and particularly to a vaginal dilating device for auxiliary cleaning in obstetrics and gynecology. Background Art

[0002] Gynecological inflammation is the most common disease in clinical gynecology. Especially in recent years, with the acceleration of people's living rhythm and irregular living habits, the incidence of gynecological inflammation has been increasing year by year. For vaginal adhesions in patients with vaginitis or after brachytherapy for cervical cancer, clinical treatment requires irrigation with medicated water. During this process, a vaginal speculum is needed. A vaginal speculum is an auxiliary tool used in reproductive medicine to dilate the vagina. After the vagina is dilated, it is convenient for doctors to perform irrigation and gynecological examinations.

[0003] In the prior art, for vaginal dilation, a duckbill blade structure is mainly used for dilation, and then a flushing tube is inserted to flush the vaginal wall. In routine operations, when using a vaginal speculum, lubricating fluid is applied or it is directly inserted into the vagina. This operation method is likely to damage the patient's vaginal wall, and during the dilation process, unilateral dilation is mostly carried out in a straight line direction, which also increases the discomfort of the patient. Summary of the Invention

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

[0010] To improve the comfort of the patient, preferably, the vibration part includes: a vibration cylinder, and end face cams are fixedly connected to the end faces of the vibration cylinder in contact with the driving cylinder. When the driving cylinder rotates, the vibration cylinder approaches or moves away from the driving cylinder; two groups of springs are respectively fixedly connected to the ends of the vibration cylinder and the driving cylinder, and the other ends of the springs are in contact with the inner wall of the flushing channel.

[0011] To improve the stability of the operation, further, damping strips are fixedly connected to the inner wall of the vibration cylinder.

Among them, a positioning cavity is opened in the cylindrical platform, the positioning cavity is communicated with the flushing nozzle, and the liquid flow direction in the flushing nozzle forms an angle with the axis L.

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

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

[0017] 1. The vaginal dilator for auxiliary cleaning in obstetrics and gynecology can extract odor and excessive outflowing liquid by generating negative pressure. The exhaust channel can be equipped with a threaded joint at the outer wall of the operating handle to connect the drainage tube to guide the waste liquid to the waste liquid bucket for centralized treatment. Some filter cotton such as activated carbon can also be plugged into the suction hole to reduce the odor discharged from the exhaust channel. Inhalation by medical staff affects the comfort of medical staff;

[0018] 2. The vaginal dilator for auxiliary cleaning in obstetrics and gynecology transmits vibration to the expansion part, causing a slight numbness in the skin, stimulating and activating sensory nerve fibers, such as Aδ and C fibers. The signal is transmitted to the spinal cord and brain, such as the nucleus accumbens or the prefrontal cortex, prompting 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;

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

[0020] 4. The vaginal stretching device for auxiliary cleaning in obstetrics and gynecology can ensure the support strength and stability of the stretching sheet by covering the supporting ribs of the rubber sheet, and after being stretched, the negative pressure hole 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, avoiding infection by waste liquid and waste liquid entering deep into the vagina, and the outer surface of the rubber sheet can also be filled with lubricating liquid, so as to reduce the dry friction with the vagina when the stretching sheet is inserted into the vagina, and effectively protect the vagina;

[0021] 5. The vaginal dilator for auxiliary cleaning in obstetrics and gynecology can adjust the position of the columnar table and push and rotate the flushing tube during cleaning. On the one hand, the expansion angle of the dilator can be changed, thereby controlling the position of water flushing, which is convenient for medical staff to choose according to individual differences of patients. On the other hand, the forced contact method can effectively transmit the vibration of the vibration cylinder to the dilator, thereby effectively reducing the discomfort of patients during the flushing process.

[0022] For the parts not involved in this device, they are the same as or can be implemented using the prior art. By controlling the opening angle of the expansion part at a deep position to be smaller than that at the external position, this invention avoids damaging the vaginal wall of the patient, improves the comfort of the patient, and at the same time facilitates 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 can also give medical staff greater freedom in expansion. Additionally, by using the negative pressure channel to extract the waste liquid and secretions generated during the cleaning process, it can further improve the safety of cleaning and the clarity of operation.

[0032] 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 of the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation 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 orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0034] Embodiment:

[0035] Refer to Figures 1-8, a vaginal dilating device for auxiliary cleaning in obstetrics and gynecology, comprising a graspable 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, a cylindrical flushing channel 101 penetrating front and back is opened along the axis L of the operating handle 1, the flushing channel 101 is a stepped through hole, the diameter near the working end is larger than the diameter near the operating end, and the diameter of the operating end is slightly larger than the diameter of the flushing tube, usually 3-5mm 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 is fixedly connected to the end face of the operating handle 1, the expansion portion is installed at 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, this method can make the vaginal opening expand larger, while the deep vagina expands smaller, which is more in line with the structure of the human body, and effectively improves the comfort of the patient, while facilitating the doctor to observe the internal The embodiment of the present invention relates to a method for controlling the vaginal discharge of a woman having a vaginal discharge and a vaginal discharge having a plurality of diaphragms. ...

[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 can be avoided, which improves the patient's comfort and facilitates medical staff to observe and judge the condition. 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 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 exhaust channel 104 that are connected to each other. 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 can be used to extract the odor and the excessive outflow liquid. The exhaust channel 104 can be equipped with a threaded joint on the outer wall of the operating handle 1 to connect the drainage tube and guide the waste liquid to the waste liquid bucket for centralized treatment. In other embodiments, the air suction hole 102 is mainly used to extract the odor gas. Therefore, some filter cotton such as activated carbon can be stuffed into the air suction hole 102 to reduce the odor inhaled by the medical staff when it is discharged from the exhaust channel 104, which affects the comfort of the medical staff's operation.

[0038] Specifically, the negative pressure part includes: negative pressure vanes 202 that are circumferentially and equidistantly distributed on the outer wall of the driving cylinder 2. The negative pressure vanes 202 are arranged between the air intake channel 103 and the exhaust channel 104 to separate the two. When the negative pressure vanes 202 revolve around the axis L, a negative pressure adsorption effect can be generated in the air intake channel 103, and a positive pressure is generated in the exhaust channel 104 to centrally discharge the odor and waste liquid; a friction ring 201 is wrapped around the periphery of the negative pressure vanes 202. A motor 8 is fixedly connected inside the operating handle 1, and a driving friction wheel 801 is installed at the output end of the motor 8. The driving friction wheel 801 is in contact with the friction ring 201. In some embodiments, in order to improve the reliability of the transmission, the friction wheel 801 and the friction ring 201 can be designed as a toothed structure to form tooth engagement. However, since the driving cylinder 2 needs to move left and right and rotate, the output shaft of the motor 8 is prismatic. A prismatic through hole is provided along the axis direction of the driving toothed friction wheel 801, and the prismatic output shaft passes through the prismatic through hole. Thus, when the output shaft rotates, it can drive the toothed friction wheel 801 to rotate and does not limit the axial displacement of the toothed friction wheel 801, so that the toothed friction wheel 801 is always engaged with the toothed friction ring 201, driving the negative pressure vanes 202 to continuously generate negative pressure in the negative pressure channel and ensuring the continuity of the extraction operation to improve 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 that are in contact are fixedly connected with end face cams 203. When the driving tube 2 rotates, the vibration tube 3 and the driving tube 2 are in contact with the two end face cams 203 on the driving tube 2, and the vibration tube 3 and the driving tube 2 are separated from each other. When the two end face cams 203 are staggered, the vibration tube 3 and the driving tube 2 are close 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 is in contact with 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 and vibration, 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, prompting 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] The inner wall of the vibration cylinder 3 is also circumferentially and equidistantly fixedly connected with 4-8 damping strips 301. When the flushing pipe passes through the inner ring channel of the vibration cylinder 3, the damping strip 301 forms an interference fit with the outer wall of the flushing pipe, thereby only covering the flushing pipe, and then effectively transmitting the vibration to the expansion part through the flushing pipe.

[0041] Specifically, the expansion part includes: two groups of expansion pieces 4, one end of the bracket 5 away from the operating handle 1 is fixedly connected to a 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 to prevent 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 spreading piece 4 includes: a circular support rib 401. A diversion channel 402 is formed inside the support rib 401. The diversion channel 402 is connected to the air inlet channel 103 through a telescopic tube 403. The telescopic tube 403 can pull the two spreading pieces 4 closer to each other to form a cylindrical shape here. A medical rubber sheet or a silica gel sheet is coated on the support rib 401. 3-6 negative pressure holes 404 are formed at both side edges of the rubber sheet. The negative pressure holes 404 are connected to the diversion channel 402. Through the support rib 401 coated with the rubber sheet, the support strength and stability of the spreading piece 4 can be ensured, and after spreading, the waste liquid and secretions generated during the cleaning process can be adsorbed into the negative pressure channel through the negative pressure holes 404 for unified discharge, thus effectively ensuring the cleaning safety and avoiding waste liquid infection and waste liquid entering the deep part of the vagina. In other embodiments, a concave structure is formed on the outer surface of the rubber sheet, and a lubricating liquid can be filled therein, so as to reduce the dry friction with the vagina when the spreading piece 4 is inserted into the vagina and effectively protect the vaginal wall.

[0043] Specifically, the driving part includes: a cylindrical platform 6. A ball hinge seat 701 is arranged on the circumferential surface of the cylindrical platform 6. The ball hinge seat 701 is fixedly connected to an abutting column 702 through a connecting rod 7. The abutting column 702 abuts against the positioning block 405, and both of them are made of ferromagnetic materials, so that they can be effectively adsorbed 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 formed inside the cylindrical platform 6 for facilitating the abutting of the flushing tube, and the positioning cavity is connected to the flushing nozzle 601. The liquid flow direction in the flushing nozzle 601 forms an angle of 30°-75° with the axis L. By adjusting the position of the cylindrical platform 6, during cleaning, by pushing and rotating the flushing tube, on the one hand, the expansion angle of the spreading piece 4 can be changed, and then the position of the water flow flushing can be controlled, which is convenient for medical staff to select according to the individual differences of patients. On the other hand, in the way of forced abutting, the vibration of the vibration cylinder 3 can be effectively transmitted to the spreading piece 4, thus effectively reducing the discomfort of the patient during the flushing process.

[0044] In some embodiments, with the impact vibration of the end face cam 203, since both the driving cylinder 2 and the vibration cylinder 3 are 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, thus forming a fluctuating negative pressure flow in the negative pressure channel. This process is transmitted to the negative pressure holes 404, which can suddenly increase the negative pressure around them. This method can prevent the negative pressure holes 404 from being blocked and can also suck in and discharge the secretions more powerfully, further improving the cleaning effect on the vagina.

[0045] In the present invention, during use, according to the individual differences of patients and the size of dilation required, the doctor abuts the abutting column 702 against the appropriate positioning block 405, passes the flushing tube through the flushing channel 101 and abuts it in the spherical positioning cavity of the columnar platform 6, and presses it against the flushing nozzle 601. During this process, the interference fit between the vibration cylinder 3 and the flushing tube is close to a rigid connection. Then, lubricating oil is applied to the surface of the spreading 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 to move along the axis L through the end face cam 203 and impacts and vibrates with the driving cylinder 2, and transmits the vibration to the spreading piece 4 through the flushing tube. Then, the patient takes the lithotomy position, exposes the vulva, and after disinfection, the non-dilated spreading piece 4 is slowly inserted into the vagina. During this process, the air suction hole 102 can suck the peculiar smell in the vagina and purify and discharge it, and the negative pressure hole 404 will suck the secretions in the vagina and the excess lubricating fluid squeezed out, and discharge them uniformly through the negative pressure channel. During the pushing process, the vibrating spreading piece 4 can reduce the foreign body sensation and discomfort of the patient. When entering the flushing process, the flushing tube is pushed. As the columnar platform 6 moves, the connecting rod 7 can gradually tend to be in a vertical state, and then the two spreading pieces 4 are symmetrically dilated in the vagina, making the dilation of the vagina conical, that is, the entrance is large and the inside 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 into the flushing nozzle 601 through the flushing tube, and at the same time, the flushing nozzle 601 can be rotated to change the flushing position. During the flushing process, the negative pressure hole 404 can suck the waste liquid and discharge it uniformly through the negative pressure channel. After the flushing is completed, the spreading piece 4 is released and pulled out synchronously with the flushing tube. Then, the flushing tube is removed, and the whole device is immersed in disinfectant or clean water, and the internal channel is flushed by means of negative pressure to ensure the safety and hygiene of use.

[0046] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
