Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a vaginal dilator used after vaginoplasty. Background Technology

[0002] Vaginoplasty is an important surgical procedure performed for specific vaginal conditions such as congenital absence of the vagina or vaginal atresia. Postoperative vaginal dilation plays a crucial role in preventing vaginal contracture, promoting wound healing, and fully restoring the patient's physiological functions. This step not only affects the final outcome of the surgery but also directly impacts the patient's quality of life and psychological well-being.

[0003] Unfortunately, the vaginal dilators currently available on the market are relatively rigid in design, with most products still using fixed sizes. This design deficiency means that the devices cannot adapt to each patient's unique recovery process and individual differences, which may lead to a series of problems: on the one hand, excessive local pressure may aggravate the patient's pain and discomfort, and even pose a potential threat to newly formed tissue; on the other hand, insufficient dilation makes it difficult to effectively prevent vaginal contracture, thus affecting the overall efficacy of the surgery and the patient's recovery process. Therefore, we propose a novel vaginal dilator for use after vaginoplasty. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vaginal dilator for use after vaginoplasty, which solves the problem that most vaginal dilators on the market still use fixed sizes, and such designs cannot adapt to the unique recovery process and individual differences of each patient's vagina.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vaginal dilator for use after vaginoplasty, comprising a base cylinder and a plurality of pipe limiting members fixedly installed on the outer circular surface of the base cylinder, wherein an dilator is provided on the outer side of the base cylinder; The expansion mechanism includes an inflation assembly, an deflation assembly, and a pressure detection assembly; The inflation assembly includes several main inflation tubes fixedly installed on the pipe limiting member. An inflation branch pipe communicating with the inner cavity of the main inflation tube is fixedly installed on the outer circumference of the main inflation tube. A unit airbag is fixedly connected to the outlet end of the inflation branch pipe. A one-way valve is fixedly installed at the inlet end of the main inflation tube. A pipe fixing sleeve is fixedly installed at the end of the main inflation tube near the one-way valve. A pipe fixing ring fixedly connected to one of the unit airbags is fixedly installed at the end of the pipe fixing sleeve away from the main inflation tube. The exhaust assembly includes a curved pipe with a valve that is fixedly installed at the outlet end of the main inflation pipe and communicates with the inner cavity of the main inflation pipe. An airflow collecting ring is fixedly installed at the end of the curved pipe away from the main inflation pipe. A plurality of exhaust branch pipes communicating with the inner cavity of the airflow collecting ring are fixedly installed on the inner circular surface of the airflow collecting ring. A main exhaust pipe communicating with the inner cavity of the airflow collecting ring is fixedly installed at the end of the exhaust branch pipe away from the airflow collecting ring. A main exhaust valve is fixedly installed at the outlet end of the main exhaust pipe. The pressure detection assembly includes four pressure sensors fixedly installed on the outer circular surface of the unit airbag. A sleeve is fixedly installed on the pressure sensor and located on the outside of the unit airbag. A sleeve head is fixedly installed at one end of the sleeve near the main exhaust valve. An antibacterial layer is fixedly installed on the outer circular surface of the sleeve.

[0006] Preferably, the number of the main inflation pipe, the branch inflation pipe, and the unit airbags are all several, and they are all in a one-to-one correspondence. The main inflation pipe is evenly distributed in a circumferential shape on the outside of the base cylinder, and the several unit airbags are stacked.

[0007] Preferably, a plurality of the valved bends and exhaust branch pipes are evenly distributed in a circumferential shape on the airflow collecting ring.

[0008] Preferably, one end of the main exhaust pipe is sealed and the other end is open, wherein the main exhaust pipe and the main inflation pipe are located on the same axis; The output end of the main exhaust valve faces the air inlet end of the main inflation pipe.

[0010] Preferably, the antibacterial layer is made of a nano-coating with hydrophilicity and a low coefficient of friction.

[0011] Preferably, the sleeve is provided with an installation positioning mechanism at one end near the one-way valve.

[0019] This invention provides a technical solution: Please see Figures 1-8 A vaginal dilator for use after vaginoplasty includes a base cylinder 1 and several tube limiting components 2 fixedly installed on the outer circular surface of the base cylinder 1. An expansion mechanism 3 is provided on the outer side of the base cylinder 1.

[0020] The expansion mechanism 3 includes an inflation component 31, an exhaust component 32, and a pressure detection component 33. Through the coordinated work of these three parts, precise expansion and pressure monitoring of the vaginal tissue are achieved, ensuring both the expansion effect and avoiding excessive compression.

[0021] The inflation assembly 31 includes several main inflation pipes 311 fixedly installed on the pipe limiting member 2. An inflation branch pipe 312, communicating with the inner cavity of the main inflation pipe 311, is fixedly installed on the outer surface of each main inflation pipe 311. A unit airbag 313 is fixedly connected to the outlet end of the inflation branch pipe 312. A one-way valve 314 is fixedly installed at the inlet end of the main inflation pipe 311. A pipe fixing sleeve 315 is fixedly installed at the end of the main inflation pipe 311 near the one-way valve 314. A pipe fixing ring 316, fixedly connected to one of the unit airbags 313, is fixedly installed at the end of the pipe fixing sleeve 315 away from the main inflation pipe 311. The design of the inflation assembly 31 allows gas to enter each unit airbag 313 in an orderly manner, achieving precise control of expansion. The one-way valve 314 ensures unidirectional gas flow, while the pipe fixing sleeve 315 and pipe fixing ring 316 enhance structural stability, providing uniform and personalized expansion force for the vagina.

[0022] The exhaust assembly 32 includes a valved bend 321 fixedly installed at the outlet end of the inflation main pipe 311 and communicating with the inner cavity of the inflation main pipe 311. An airflow collecting ring 322 is fixedly installed at the end of the valved bend 321 away from the inflation main pipe 311. Several exhaust branch pipes 323 communicating with the inner cavity of the airflow collecting ring 322 are fixedly installed on the inner circular surface of the airflow collecting ring 322. A main exhaust pipe 324 communicating with the inner cavity of the airflow collecting ring 322 is fixedly installed at the end of the exhaust branch pipe 323 away from the airflow collecting ring 322. A main exhaust valve 325 is fixedly installed at the outlet end of the main exhaust pipe 324. The design of the exhaust assembly 32 allows for precise control of the exhaust process of the control unit airbag 313. The valved bend 321, airflow collecting ring 322, exhaust branch pipes 323, main exhaust pipe 324 and main exhaust valve 325 achieve orderly gas discharge, facilitate adjustment of expansion force, and ensure patient safety and comfort.

[0023] The pressure detection assembly 33 includes four pressure sensors 331 fixedly installed on the outer circular surface of the unit airbag 313. A sleeve 332 is fixedly installed on the pressure sensors 331 and located on the outside of the unit airbag 313. A sleeve head 333 is fixedly installed at one end of the sleeve 332 near the main exhaust valve 325. An antibacterial layer 334 is fixedly installed on the outer circular surface of the sleeve 332. The expansion force of the unit airbag 313 is monitored in real time through the four pressure sensors 331. The sleeve 332 and sleeve head 333 protect the sensors and enhance comfort. The antibacterial layer 334 prevents infection, ensures the expansion process is safe and accurate, and improves the patient's recovery effect.

[0024] Furthermore, the number of inflation main tubes 311, inflation branch tubes 312, and unit airbags 313 are all several and correspond one-to-one. The inflation main tubes 311 are evenly distributed in a circular shape on the outside of the base cylinder 1, and the unit airbags 313 are stacked. With the inflation main tubes 311, inflation branch tubes 312, and unit airbags 313 all several and correspond one-to-one, the inflation main tubes 311 are distributed in a circular shape, and the unit airbags 313 are stacked, this design allows the device to perform personalized, multi-level expansion according to the vaginal shape and recovery needs of different patients, improving the expansion effect and comfort.

[0025] Furthermore, several valved bends 321 and exhaust branch pipes 323 are evenly distributed in a circular shape on the airflow collecting ring 322. The even distribution of the valved bends 321 and exhaust branch pipes 323 in a circular shape ensures uniform gas discharge, avoids uneven expansion caused by excessive local exhaust, and improves the expansion effect and patient comfort.

[0026] Furthermore, one end of the main exhaust pipe 324 is sealed and the other end is open. The main exhaust pipe 324 and the inflation main pipe 311 are located on the same axis. By sealing one end of the main exhaust pipe 324 and opening the other end, and designing it coaxially with the inflation main pipe 311, the gas emission is concentrated and orderly, avoiding gas leakage. At the same time, it facilitates exhaust, improves exhaust efficiency and ease of operation.

[0027] The output end of the main exhaust valve 325 faces the inlet end of the inflation main pipe 311. This design facilitates centralized gas discharge while ensuring that the exhaust process and inflation operation do not interfere with each other, thus improving the ease of operation and practicality of the device.

[0028] Furthermore, the base cylinder 1 is made of rigid silicone. By making the base cylinder 1 of rigid silicone, a stable support structure is provided, ensuring that the expansion mechanism 3 can evenly distribute pressure during inflation, thereby improving the expansion effect. At the same time, the rigid material also facilitates the insertion and fixation of the device, enhancing the convenience and comfort of use.

[0029] Both the sleeve 332 and the head 333 are made of soft silicone. The head 333 is in the shape of a hollow hemisphere. The use of soft silicone for both the sleeve 332 and the head 333 increases the fit with the vaginal wall and the patient's comfort. In particular, the hollow hemisphere design of the head 333 allows for gentler contact with vaginal tissue, reducing friction and discomfort.

[0030] Furthermore, the antibacterial layer 334 is made of a nano-coating with hydrophilicity and low coefficient of friction. By using a nano-coating with hydrophilicity and low coefficient of friction, the friction between the device and the vaginal mucosa is reduced, improving comfort. At the same time, its antibacterial and anti-inflammatory functions effectively prevent postoperative infection, promote tissue repair, and ensure patient safety.

[0031] Furthermore, a mounting and positioning mechanism 4 is provided at the end of the sleeve 332 near the one-way valve 314. The mounting and positioning mechanism 4 includes four linkage columns 41 fixedly installed at the end of the sleeve 332 near the one-way valve 314. An installation ring 42 is fixedly installed at the end of the linkage column 41 away from the sleeve 332. A double-sided adhesive tape 43 is provided on the side of the installation ring 42 away from the linkage column 41. Through the mounting and positioning mechanism 4 and its double-sided adhesive tape 43, the patient can easily fix the device to his underwear, ensuring that the dilation mechanism 3 is stable and does not slip in the vagina, which is convenient for daily activities and improves the convenience of the treatment process and the patient's comfort.

[0032] Furthermore, the mounting ring 42 is made of latex material. The use of latex material in the mounting ring 42 enhances its fit and comfort against the skin. At the same time, the elasticity of latex helps to provide a better seal during installation, ensuring that the double-sided tape 43 can firmly fix the device to the underwear and prevent it from falling off.

[0033] In practical use, the working principle of this invention is as follows: When using this vaginal dilator after vaginoplasty, patients must first ensure the entire device is clean and sterile before gently inserting it into the vagina. The outer surface of the device is covered with an antibacterial layer 334 made of a hydrophilic and low-friction nano-coating. This design not only significantly reduces friction and irritation between the device and the vaginal mucosa, greatly improving patient comfort, but also its antibacterial, anti-inflammatory, and tissue-repair-promoting bioactive functions effectively prevent complications such as infection, providing additional safety for the patient's postoperative recovery.

[0034] Next, the patient needs to adjust the dilation mechanism 3 of the device according to their individual recovery needs and vaginal shape. The specific operating steps are as follows: First, using an external inflation device, such as a manual or electric air pump, align the output port of the inflation device with the inlet port of any one-way valve 314. As gas is continuously injected, the gas enters the corresponding inflation main pipe 311 through the one-way valve 314 and is guided to the corresponding unit airbag 313 via the inflation branch pipe 312, causing it to gradually inflate.

[0035] Meanwhile, the pressure detection component 33 begins to function. As the unit airbags 313 inflate, they push the outer wall of the sleeve 332 into close contact with the vaginal wall. During this process, the pressure sensor 331, located between the unit airbags 313 and the sleeve 332, can sense and report changes in force in real time. This data can be transmitted wirelessly to an external device controller, allowing patients or medical personnel to view the data transmitted by each pressure sensor 331 in real time via a mobile app or computer software, thereby accurately determining the degree of contact between the device and the vaginal tissue and whether the expansion force is appropriate.

[0036] To achieve precise dilation of different parts of the vagina, the patient needs to inflate all remaining unit balloons 313 one by one according to the preset inflation sequence and force until they are tightly fitted to the corresponding vaginal walls. By adjusting the inflation volume of each unit balloon 313, its expansion volume can be precisely controlled, thereby achieving the best dilation effect on the vaginal tissue.

[0037] During dilation, if the patient feels excessive pressure or discomfort in a certain area of ​​vaginal tissue, inflation of the unit airbag 313 at that location can be stopped immediately. By controlling the valve switch on the corresponding curved tube 321 with a valve and the main exhaust valve 325, some of the gas inside the unit airbag 313 can be released, thereby reducing its volume and adjusting the dilation force. This process can be precisely guided by observing changes in pressure data, ensuring that the dilation force at each point is just right, avoiding pain and discomfort caused by excessive pressure while ensuring the effectiveness of the dilation effect.

[0038] Furthermore, the device's design fully considers individual patient differences and recovery processes. By adjusting the inflation volume of different unit airbags 313, it can flexibly adapt to the vaginal shape and recovery needs of different patients, providing personalized treatment plans for each patient. Simultaneously, the device uses a base tube 1 made of rigid silicone and sleeves 332 and head 333 made of soft silicone, ensuring the device's stability and comfort. The addition of an antibacterial layer 334 further enhances the device's safety and reliability.

[0039] Once the dilation mechanism 3 is adjusted to the appropriate degree of dilation to match the patient's vaginal wall, the patient can use the installation and positioning mechanism 4 to secure the device. Specifically, peel off the protective film from the double-sided adhesive tape 43 in the installation and positioning mechanism 4, and then attach it to the appropriate position on the patient's underwear, ensuring the device remains stable inside the vagina and does not easily slip or shift. In this way, the patient can continue vaginal dilation treatment without affecting daily activities.

[0040] In summary, this vaginal dilator, with its unique design and flexible operation, provides patients after vaginoplasty with an efficient, safe, and comfortable dilation solution, which helps promote the healing of surgical wounds and the full recovery of vaginal tissues.

[0041] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
