Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adaptive vaginal dilator and irrigator. Background Technology

[0002] Cervical cancer is one of the most common malignant tumors of the female reproductive system. Its treatment is often accompanied by a variety of local complications, which seriously affect the treatment effect, quality of life and survival prognosis of patients. Among them, abnormal accumulation of vaginal and uterine secretions, and stenosis and adhesion of the vagina and cervix are key issues that urgently need to be addressed in clinical practice.

[0003] In the clinical diagnosis, treatment, and nursing care of cervical cancer patients, uterine irrigation is an important local treatment measure. Due to the invasiveness of cervical cancer lesions and the stimulation of local tissues during treatment, patients often produce a large amount of secretions in the vagina and uterine cavity. If these secretions are not removed in a timely and thorough manner, they will accumulate in the vagina and uterine cavity for a long time, which will not only aggravate the local inflammatory response, but may also become a breeding ground for bacteria, thereby inducing infection and affecting the treatment process. Therefore, it is necessary to perform regular and thorough local irrigation of the patient's vagina and uterine cavity to remove secretions, maintain local cleanliness, and create a good local environment for treatment.

[0004] Meanwhile, for cervical cancer patients undergoing radiotherapy, vaginal dilation is an indispensable adjuvant treatment. During cervical cancer radiotherapy, radiation can cause damage to the vagina and cervical tissues, leading to pathological changes such as congestion, edema, and fibrosis. If vaginal dilation is not performed in time, the damaged tissues will gradually contract and adhere after radiotherapy, leading to vaginal and cervical stenosis, and in severe cases, severe adhesions. Once severe adhesions occur, secretions produced in the uterine cavity cannot be discharged normally, and long-term accumulation in the uterine cavity can cause uterine fluid accumulation, further leading to secondary bacterial infections. In severe cases, it can lead to serious complications such as bacteremia, which not only significantly reduces the patient's quality of life but also adversely affects their survival time. Therefore, regular vaginal dilation during and after radiotherapy is a key means of preventing vaginal and cervical stenosis and adhesions.

[0005] However, the related instruments currently used in clinical practice generally have the defect of being single-function: either they only have the function of vaginal dilation, which can only achieve mechanical dilation of the vagina to prevent adhesions, but cannot effectively flush secretions in the vagina and uterine cavity, making it difficult to solve the problem of secretion accumulation; or they only have the function of uterine cavity flushing, which can only remove secretions, but cannot achieve vaginal dilation, and cannot prevent stenosis and adhesions of the vagina and cervix after radiotherapy, as in reference 1.

[0006] Reference 1: Chinese patent document with publication number CN 120000390 A.

[0007] Reference 1 describes an intrauterine stent for preventing intrauterine adhesions, comprising: a push rod, one end of which is slidably connected to a fixed rod; a stent body, which is mounted on the fixed rod; and a balloon. The push rod is used to inflate the balloon, which enters the uterine cavity through the fixed rod and, upon inflation, causes the stent body to deploy. Upon entering the uterine cavity, the push rod encloses the balloon and the stent body, allowing for smooth entry into the cervix. This prevents discomfort to the patient due to the stent body's large size. After deployment within the uterine cavity and inflation of the balloon, the deployment speed of the stent body is reduced, minimizing damage to the uterine cavity.

[0008] Based on the aforementioned clinical needs and the shortcomings of existing technologies, there is an urgent clinical need for a special device that combines multiple functions. This device can effectively flush the vagina and uterine cavity, thoroughly remove locally accumulated secretions, and simultaneously perform vaginal dilation operations to effectively prevent stenosis and adhesions of the vagina and cervix after radiotherapy, thereby reducing the occurrence of complications and improving the patient's quality of life. Summary of the Invention

[0009] The purpose of this invention is to solve the above-mentioned technical problems existing in the prior art and to provide an adaptive vaginal dilator and irrigator.

[0010] To address the shortcomings of the aforementioned technical problems, the present invention provides the following technical solution: an adaptive vaginal dilator and irrigator, comprising: The main body is a cylindrical structure with a hemispherical cover at the head, the hemispherical cover having multiple through holes, and a gripping part at the tail; and A partition, disposed inside the main body along its axial direction, extends from the first end to the upper part of the main body and from the second end to the middle part of the main body, forming a left chamber and a right chamber on either side of the partition; and Multiple nozzles are correspondingly positioned at each through-hole in the hemispherical cover and the main body; and Multiple capsules are distributed circumferentially on the outer wall of the main body. Each capsule is inflatable, and a through-hole is provided on the outer wall of the main body between adjacent capsules. The first diversion valve is located at the top of the left chamber and is connected to each nozzle via piping; and The second diversion valve is located at the top of the right chamber and is connected to each bladder via tubing; and A regulating valve, located at the second end of the partition, is used to control the opening and closing of the left and right chambers. The regulating valve has a first operating state and a second operating state. In the first operating state, the left chamber is closed and the right chamber is open; in the second operating state, the left chamber is open and the right chamber is closed. The traction line is configured to drive the regulating valve to switch from a first operating state to a second operating state based on the expansion of the bladder.

[0011] As a further optimization of the adaptive vaginal dilator of the present invention: the regulating valve includes a central shaft, a blade assembly sleeved on the central shaft, and a torsion spring. The blade assembly includes a left blade and a right blade, which are at a 90-100° angle. The torsion spring is disposed between the central shaft and the blade assembly to keep the left blade in a horizontal position in the initial state to close the left chamber and open the right chamber.

[0012] As a further optimization of the adaptive vaginal dilator of the present invention: the elastic force of the torsion spring is configured such that: in the initial state, it can stably keep the left blade closed to the left side chamber, and when the tension of the traction line is greater than a preset threshold, it can drive the right blade to flip.

[0013] As a further optimization of the adaptive vaginal dilator of the present invention: one end of the traction line is connected to the inner wall of one of the cysts, and the other end is connected to the right blade. When the cyst expands, the traction line pulls the right blade to flip until the right blade closes the right chamber, while the left blade opens the left chamber.

[0014] As a further optimization of the adaptive vaginal dilator of the present invention: the main body is provided with a guide, the traction wire bypasses the guide to change its direction, the traction wire extends into the bladder through the tube corresponding to the bladder and is fixedly connected to the inner wall of the bladder.

[0015] As a further optimization of the adaptive vaginal dilator of the present invention: the number of sacs is 6-12, and the sacs are columnar after expansion.

[0016] As a further optimization of the adaptive vaginal dilator of the present invention: the capsule is made of elastic medical rubber material, and the connecting tubes of the capsule are all medical silicone tubes.

[0017] As a further optimization of the adaptive vaginal dilator of the present invention: the through holes on the hemispherical cover are divided into upper and lower layers, the lower layer has more through holes than the upper layer, and the two layers of through holes are staggered.

[0018] As a further optimization of the adaptive vaginal dilator of the present invention: both the first diversion valve and the second diversion valve include a disc-shaped valve body. The outer wall of the valve body is sealed to the inner wall of the main body and the partition. The valve body has several flow channels arranged parallel to its axis inside. The flow channels are correspondingly provided with interfaces. One end of the pipeline is inserted into the interface of the diversion valve. The inner wall of the interface is provided with an annular sealing groove, and a sealing ring is embedded in the sealing groove.

[0019] This invention offers the following advantages: It integrates vaginal dilation and uterine cavity irrigation functions into one unit. An internal partition separates the main body into independent left and right chambers, providing power for irrigation and cyst expansion, respectively. The elastic cysts, circumferentially distributed on the outer wall, expand to create a uniform expansion force on the vaginal wall, preventing vaginal and cervical stenosis and adhesions after radiotherapy. Furthermore, the expansion force of the cysts is adapted to the human physiological structure, avoiding mucosal damage. An adaptive function is achieved through the linkage of a traction wire and a regulating valve. When the cysts expand to a preset level, the traction wire automatically drives the regulating valve to switch operating states. After expansion, the irrigation mode is seamlessly activated without manual adjustment. Attached Figure Description

[0021] To better understand the present invention, the following embodiments further illustrate the content of the present invention, but the content of the present invention is not limited to the following embodiments.

[0022] like Figure 1-3 As shown: An adaptive vaginal dilator includes a main body 1, a partition 2, multiple nozzles 3, multiple bladders 4, a first diversion valve 5, a second diversion valve 6, an adjusting valve 7, and a traction wire 8.

[0023] The main body 1 is a cylindrical structure made of medical-grade rigid silicone. Its head has a smooth hemispherical cover 101 integrally formed to avoid scratching the vaginal mucosa during insertion. The hemispherical cover 101 has two layers of staggered through holes 101, with 8 through holes in the lower layer and 6 through holes in the upper layer. Each through hole 101 corresponds to a medical silicone nozzle 3, and the water outlet end of the nozzle 3 is flush with the outer wall of the hemispherical cover 101. The tail of the main body 1 has a grip part 103, and the surface of the grip part 103 is frosted for easy gripping during operation.

[0024] A medical plastic partition 2 is fixed inside the main body 1 along the axial direction. The first end of the partition 2 extends to the upper part of the main body 1, and the second end extends to the middle part of the main body 1. A left chamber 201 and a right chamber 202 are formed on both sides of the partition 2, providing independent channels for the flushing function and the adaptive adjustment function.

[0025] Eight capsules 4 are evenly distributed along the circumference of the outer wall of the main body 1. The capsules 4 are made of elastic medical-grade rubber material. Initially, they fit tightly against the outer wall of the main body. After expansion, they form a columnar structure, which can evenly exert an expansion force on the vaginal wall, avoiding excessive local pressure that could cause mucosal damage. Each capsule 4 is connected to the right 202 chamber via a medical-grade silicone tube. The silicone tube is arranged along the inner wall of the main body and is sealed to prevent leakage of the irrigation fluid. A through-hole 102 is provided on the outer wall of the main body 1 between two adjacent capsules 4. A medical-grade silicone nozzle 3 is fixed within each through-hole 102, and this nozzle 3 is used to rinse the vaginal wall.

[0026] The top of the left chamber 201 is equipped with a first diversion valve 5, and the top of the right chamber 202 is equipped with a second diversion valve 6. Both are disc-shaped medical plastic valve bodies. The outer wall of the valve body is sealed to the inner wall of the main body and the partition through a sealing ring. The valve body has an axial flow channel matching the number of nozzles 3 and bladders 4. The flow channel interface is provided with an annular sealing groove and a sealing ring is embedded. After the pipeline is inserted, a sealed connection is achieved. The first diversion valve 5 is connected to each nozzle 3 through a pipeline, and the second diversion valve 6 is connected to each bladder 4 through a pipeline.

[0027] The second end of the partition 2 is provided with a regulating valve 7. The regulating valve 7 consists of a central shaft, a blade assembly and a torsion spring. The blade assembly includes a left blade 701 and a right blade 702, which are fixed on the central shaft at a 95° angle. The torsion spring is sleeved between the central shaft and the blade assembly. In the initial state, the elastic force of the torsion spring keeps the left blade 701 in a horizontal position and closes the left chamber 201, while the right chamber 202 is in an open state.

[0028] The main body 1 is equipped with a plastic guide. One end of the traction wire 8 passes through the connecting pipe of the bladder 4 and is fixedly connected to the inner wall of one of the bladders 4. The other end passes around the guide and changes direction before being connected to the right blade 702. The elastic preset threshold of the torsion spring is adapted to the effective expansion stroke of the bladder 4, ensuring that when the bladder 4 expands to the preset degree, the tension of the traction wire 8 can overcome the elastic force of the torsion spring and drive the blade assembly to flip.

[0029] The irrigation solution used is sterile saline or clinically specific gynecological irrigation solution. During use, the patient holds the handle of the irrigation device and slowly inserts the head into the vagina until the hemispherical cover reaches near the cervix. The start switch is turned on, and the irrigation solution enters each cyst through the right chamber and the second diversion valve. The cysts gradually expand, creating a uniform expansion force on the vaginal wall, achieving vaginal dilation and preventing stenosis and adhesions. When the cysts expand to the preset level (adapted to the normal dilation size of an adult vagina), the traction wire is simultaneously tightened. Its tension overcomes the torsion spring force, causing the right blade to rotate around the central axis until the right blade closes the right chamber. The left blade rotates with the blade assembly to the open state, and the regulating valve completes the adaptive switching from the first working state to the second working state. The cysts stop expanding and maintain a stable dilation state.

[0030] After the regulating valve is switched, the flushing fluid is delivered to each nozzle through the left chamber and the first diversion valve. It is then sprayed out at multiple angles through the through holes of the hemispherical cover to thoroughly flush the cervix, uterine cavity, and vaginal wall, effectively removing secretions. The waste fluid after flushing flows out naturally with the body position, achieving a thorough cleaning effect. During the flushing process, the capsule remains in an expanded state to prevent the vaginal wall from adhering and affecting the flushing effect.

[0031] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
