Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a vaginal speculum for examining gynecological tumor patients. Background Technology

[0002] Currently, vaginal examination is an extremely important procedure in the diagnosis and treatment of gynecological diseases, especially for patients with gynecological tumors. Vaginal speculum, as a commonly used medical device, is used to dilate the vagina so that doctors can clearly observe the condition of the inside of the vagina and the cervix, thereby enabling accurate diagnosis, sampling, and treatment.

[0003] Traditional vaginal speculae are mostly simple structures made of metal or plastic blades, which have some shortcomings in use. For example, their structure is relatively simple, only achieving basic vaginal dilation, and they lack consideration for comfort. During the examination, the cold instrument directly contacts the patient's vaginal tissue, which can easily cause discomfort or even pain, especially for more sensitive patients or those requiring prolonged examinations. Furthermore, traditional speculae are not convenient or precise enough in fixing the degree of dilation, potentially requiring doctors to spend considerable time and effort adjusting them, thus affecting examination efficiency.

[0004] Therefore, it is necessary to develop a new type of vaginal speculum for examining gynecological tumor patients in order to overcome the shortcomings of existing technologies, improve the quality and efficiency of gynecological examinations, and reduce patient suffering. Utility Model Content

[0005] In order to improve the quality and efficiency of gynecological examinations and reduce the discomfort of patients during vaginal examinations, this application provides a vaginal speculum for examination of gynecological tumor patients.

[0006] This application provides a vaginal speculum for examining gynecological tumor patients, employing the following technical solution: it includes an expansion component and an expansion and fixation mechanism. The expansion component comprises two symmetrically arranged expansion parts, each including a fixed housing. The fixed housing is concave-arc shaped, with one end being arc-shaped. The other end of the fixed housing is fixed to the expansion and fixation mechanism. A thin film is provided on the opposite sides of each of the two fixed housings. The film covers the outer side of its corresponding fixed housing and forms a cavity between it and the fixed housing. The cavity contains heatable water, and an electric heating rod is provided within the cavity and fixed to the fixed housing.

[0007] Optionally, the expansion fixing mechanism includes two fixing plates corresponding to the expansion members. Movable plates are respectively provided on the left and right sides of the end of the fixing plate away from the expansion member. Threaded holes are provided on the movable plates of one of the fixing plates, and rotatable rotating screws are provided on the movable plates of the other fixing plate. The rotating screws correspond to the threaded holes one by one. A drive motor is provided at the bottom of the two rotating screws, and the drive motor is fixed on the fixing plate on its corresponding side.

[0008] Optionally, the expansion member has a through-hole shaped medicine loading hole in the middle.

[0009] Optionally, a guide cylinder is provided at the upper end of the threaded hole, and the guide cylinder is fixed on the movable plate on its corresponding side.

[0010] Optionally, one of the fixing plates is provided with guide rods on both sides, and the other fixing plate is provided with guide holes corresponding to the guide rods.

[0011] Optionally, one of the expansion members is provided with a control switch, and a rechargeable battery pack is provided on the expansion member. The control switch is electrically connected to the electric heating rod, the drive motor, and the rechargeable battery pack.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The present invention provides a thin film on the outside of the fixed shell of the dilator and fills the cavity between the thin film and the fixed shell with heatable water. The water is heated by an electric heating rod so that the vaginal speculum has a suitable temperature when it enters the patient's vagina, avoiding the discomfort caused by cold instruments, effectively relieving the patient's tension, and improving the patient's comfort during examination and treatment.

[0014] 2. The medication application hole in the middle of the expander is a through hole. When performing local medication treatment related to gynecological tumors, doctors can directly and accurately deliver the medication to specific parts inside the vagina through the medication application hole, so that the medication can be more evenly distributed in the lesion area, improving the accuracy and effectiveness of medication application, while also simplifying the medication application process and improving treatment efficiency.

[0015] 3. The dilation and fixation mechanism adopts a combination design of two fixed plates, a movable plate, a rotating screw, and a drive motor. The drive motor drives the rotating screw to rotate, thereby changing the relative distance between the two fixed plates, achieving stable dilation and precise adjustment of the dilator. This structure can adapt to the physiological differences of different patients' vaginas, ensuring that the vaginal speculum can maintain a stable dilation state during examination and treatment, providing doctors with a clear operating field of vision, and helping to improve the accuracy of examination and treatment. At the same time, a control switch and a rechargeable battery pack are set on the dilator, which facilitates the operation and control of the electric heating rod and drive motor by medical staff.

Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5One embodiment shown includes an expansion member 1 and an expansion fixing mechanism 2. The expansion member 1 includes two symmetrically arranged expansion parts 3. Each expansion part 3 includes a fixing shell 4, which is concave-arc shaped. One end of the fixing shell 4 is arc-shaped, and the other end of the fixing shell 4 is fixed to the expansion fixing mechanism 2. A thin film 5 is fixedly connected to the opposite sides of the two fixing shells 4. The film 5 covers the outer side of its corresponding fixing shell 4 and has a cavity 6 between it and the fixing shell 4. The cavity 6 contains heatable water, and an electric heating rod 7 is fixedly connected to the cavity 6 and fixed to the fixing shell 4. In this embodiment, the expansion member... 1 is the core component for achieving vaginal dilation, consisting of two symmetrical dilators 3. The concave and circular arc designs of its fixing shell 4 are used to conform to the vaginal wall and facilitate insertion into the vagina, reducing damage to vaginal tissues. The cavity 6 between the membrane 5 and the fixing shell 4, along with the heatable water and electric heating rod 7 inside, are designed to regulate the temperature of the speculum, ensuring it is close to body temperature during use. This avoids discomfort caused by cold instruments and enhances the patient's experience during the examination. This design is particularly helpful for gynecological tumor patients, who are physically and psychologically sensitive, as it helps alleviate their anxiety and facilitates the smooth conduct of examinations and treatments.

[0024] Implementation principle: After the electric heating rod 7 is connected to the circuit, the current passes through the resistance wire of the electric heating rod 7, and the resistance wire generates heat. The heat is transferred to the water in the cavity 6, raising the water temperature. As a heating medium, the water can evenly transfer heat to the entire surface of the membrane 5, thereby allowing the vaginal speculum to reach a suitable temperature. For example, the water temperature can be heated to about 37°C, which is close to the human body temperature. In this way, when the vaginal speculum is inserted into the patient's vagina, the patient will hardly feel any cold stimulation, effectively improving the patient's comfort.

[0025] Reference Figure 2 , Figure 4One embodiment shown is as follows: The expansion fixing mechanism 2 includes two fixing plates 8 corresponding one-to-one with the expansion member 3. Movable plates 9 are respectively provided on the left and right sides of the fixing plate 8 at the end away from the expansion member 3. Each movable plate 9 on one fixing plate 8 has a threaded hole 10 (thread lines not shown). Each movable plate 9 on the other fixing plate 8 is rotatably connected to a rotatable rotating screw 11. The rotating screw 11 corresponds one-to-one with the threaded hole 10. The bottoms of the two rotating screws 11 are respectively fixedly connected to the output end of the drive motor 12. The drive motor 12 is fixed on the fixing plate 8 on its corresponding side. A guide cylinder 14 is fixedly connected to the upper end of the threaded hole 10. Fixed on the corresponding side of the movable plate 9, the two fixed plates 8 are respectively connected to the two expansion members 3. Through the cooperation of the threaded hole 10 on the movable plate 9 and the rotating screw 11, the relative position between the expansion members 3 is adjusted under the drive of the drive motor 12, thereby changing the degree of expansion of the vaginal speculum. This structural design allows the vaginal speculum to adapt to the physiological differences of the vagina of different patients, achieve precise expansion adjustment, provide doctors with a clear and stable operating field, ensure the accuracy and effectiveness of examination and treatment operations, and this adjustment method of driving the screw by the motor is more convenient, faster and more accurate than the traditional manual adjustment, improving the efficiency of medical operations.

[0026] Reference Figures 1-5 One embodiment shown is as follows: a control switch 17 is connected to one of the expansion members 3 via a connecting wire, and a rechargeable battery pack 18 is fixedly connected to the expansion member 3. The control switch 17 is electrically connected to the electric heating rod 7, the drive motor 12, and the rechargeable battery pack 18. The control switch 17 allows medical staff to directly control the electric heating rod 7 and the drive motor 12 during operation, improving the convenience of operation. The rechargeable battery pack 18 provides power to the electric heating rod 7 and the drive motor 12, freeing the vaginal speculum from dependence on external power, enhancing its portability, and enabling its use in more different medical environments.

[0027] Implementation principle: When vaginal dilation is required, the drive motor 12 is started, which drives the rotating screw 11 to rotate. Due to the cooperation between the rotating screw 11 and the threaded hole 10 and the guiding effect of the guide cylinder 14 on the rotating screw 11, the distance between the two fixed plates 8 gradually increases or decreases, thereby driving the two dilators 3 to move relative to each other, so as to realize the dilation or contraction adjustment of the vagina.

[0028] Reference Figure 4 One embodiment shown is as follows: the expansion member 3 has a through-hole-shaped drug delivery hole 13 in the middle. The drug delivery hole 13 on the expansion member 3 is through-hole-shaped. During the treatment of gynecological tumors, when it is necessary to apply local medication to the inside of the vagina, medical staff can directly deliver the medication to a specific part inside the vagina through the drug delivery hole 13.

[0029] Reference Figure 3 , Figure 4 One embodiment is shown as follows: guide rods 15 are fixedly connected to both sides of one of the fixing plates 8, and guide holes 16 corresponding to the guide rods 15 are opened on the other fixing plate 8. The cooperation between the guide rods 15 and the guide holes 16 constrains and guides the relative movement of the fixing plates 8 from another dimension. Together with the guide cylinder 14, it further enhances the overall stability and movement accuracy of the expansion and fixing mechanism 2. During the expansion or contraction of the vaginal speculum, the guide rods 15 slide in the guide holes 16, restricting the other degrees of freedom of the fixing plates 8 except for the expected direction. This prevents the fixing plates 8 from shaking or misaligning due to external interference or wear of mechanical parts, ensuring that the vaginal speculum can work stably and reliably under different usage environments and operating conditions, providing more reliable instrument support for the examination and treatment of gynecological tumor patients.

[0030] The working principle of this device is as follows: During the examination and treatment of gynecological tumor patients, medical staff first start the electric heating rod 7 to preheat the vaginal speculum by controlling switch 17 according to the patient's condition, so that it reaches a suitable temperature. Then, the dilator 3 of the vaginal speculum is slowly inserted into the patient's vagina, the drive motor 12 is started, and the degree of dilation of the dilator 3 is adjusted as needed to fully expose the examination and treatment sites inside the vagina. When performing medication application, the medication is accurately delivered to the lesion area through the medication application hole 13 of the dilator 3.

[0031] The working principle of this device has been explained through the above embodiments. These embodiments merely illustrate several implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
