Description

Technical Field

[0001] The present disclosure relates to the field of female pelvic floor medical aesthetics, and more particularly, to an implantable device and an implantable kit for vaginal tightening. Background Art

[0002] Vaginal laxity syndrome (VLS) may be an early or mild clinical manifestation of pelvic floor dysfunction. It was only in recent years that it was gradually recognized by the academic community as a sexual dysfunction syndrome related to pelvic organ prolapse. Although the causal relationship between VLS and childbirth has not yet been clearly established, experts today generally believe that some vaginal deliveries can lead to damage to the pelvic floor, particularly the levator ani muscles. Studies have shown that both vaginal delivery and levator ani muscle damage are associated with an increase in the diameter of the levator ani hiatus. Therefore, vaginal laxity is likely a clinical manifestation caused by excessive expansion or damage to the levator ani muscles, which in turn seriously affects women's sexual function and intimacy.

[0003] Currently, mainstream aesthetic medical treatments are divided into minimally invasive treatments and traditional surgical procedures. Minimally invasive treatments can be further divided into laser therapy and temperature-controlled radiofrequency therapy. Laser therapy works by applying laser energy to the vaginal mucosa, stimulating collagen production and reorganization, thereby tightening the vagina. However, studies have shown that most women who undergo laser therapy experience immediate symptoms such as itching, burning, and redness and swelling, which may also be accompanied by other adverse reactions such as vaginal discharge, urinary tract infections, dysuria, yeast infections, and pelvic pain. Temperature-controlled radiofrequency therapy uses radiofrequency energy to heat vaginal tissue, promoting collagen contraction and regeneration, thereby achieving vaginal tightening. However, due to the limited number of patients included and reliable clinical data, its long-term safety cannot be guaranteed. Traditional surgical treatment, due to its invasive nature, carries potential adverse effects such as infection, bleeding, and postoperative scarring. Furthermore, the cost and postoperative recovery requirements pose significant challenges to its development.

[0004] Given the many limitations of existing treatment technologies in terms of efficacy and safety, there is an urgent need for improved pelvic floor medical aesthetic technologies in this field to better meet the needs of patients and improve their quality of life. Summary of the Invention

[0005] This disclosure is provided to introduce some concepts in a simplified form that will be further described in the following detailed description. This disclosure is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0006] In response to the problems existing in the prior art, the present disclosure provides an implantable device and kit for vaginal tightening. By installing the device and kit of the present disclosure on the female pelvic floor, the female pelvic floor can be properly fixed and squeezed, thereby improving the pelvic floor and vaginal relaxation caused by childbirth and other reasons in women, thereby improving the quality of life and achieving the purpose of medical beauty in a scientific, safe and efficient way.

[0011] According to a further embodiment of the present disclosure, the amount of expansion displacement of the cystic member is adjusted by controlling the amount of the flowing substance injected into the filling cavity.

[0012] According to another embodiment of the present disclosure, the cystic member connects two symmetrical drum surfaces through a positioning arc surface to form a cavity, and the cystic member is detachably coupled to the fixing bracket through a fitting surface opposite to the positioning arc surface.

[0013] According to another embodiment of the present disclosure, the implantable device further includes a filling through-hole provided on the fixing bracket or the cystic member so as to inject the flowing substance into the filling cavity through the filling through-hole, and after the injection of the flowing substance is completed, the filling through-hole is sealed by a sealing piece corresponding to the filling through-hole.

[0026] The present disclosure will be described in detail below in conjunction with the accompanying drawings, and the features of the present disclosure will be further apparent in the following detailed description. In the following detailed description, many specific details are set forth to provide a thorough understanding of the described exemplary embodiments. However, it will be apparent to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other exemplary embodiments, well-known structures or processing steps are not described in detail to avoid unnecessarily obscuring the concepts of the present disclosure.

[0027] In this specification, unless otherwise stated, the term "A or B" used throughout this specification refers to "A and B" and "A or B", and does not mean that A and B are excluded.

[0028] Figure 1 A schematic diagram of an implantable kit for vaginal tightening according to one embodiment of the present disclosure is shown. The implantable kit may include a pair of implantable devices, each of which is fixed to two sides of the patient's pelvis.

[0029] like Figure 1 As shown, within the pelvic floor system 40, the pelvis 180 is a ring-shaped structure composed of multiple bones, including the pubic bone 41, the ischium 42, and the sacrum 47. Its primary function is to support the weight of the human body and provide protection and support for many important internal organs. The size and shape of the pelvis 180 have a significant impact on the function of the female reproductive system. For example, during childbirth, the size and shape of the pelvis 180 can affect the passage of the fetus.

[0030] The pelvic cavity is a space within the pelvis that contains numerous important organs and tissues, such as the urethra43, vagina44, and rectum45. These organs are connected to the pelvic wall through structures such as ligaments, fascia, and muscles, forming a complex support system that maintains their normal position and function within the body. The vagina44 is a key structure within the pelvic cavity, running from front to back and connecting the cervix and vulva.

[0031] Vaginal laxity refers to the loss of elasticity in the muscles and connective tissues of the vaginal wall, resulting in an increase in vaginal diameter or a decrease in contractile force. This is often caused by the fetus's passage through the birth canal, which stretches the local mucosa, fascia, and muscle tissue, leading to relaxation of the vaginal wall, the levator ani muscles,46, and related structures of the urogenital diaphragm. Vaginal laxity can pose numerous risks. In terms of sexual intercourse, it can reduce the sensation of friction and stimulation during intercourse, diminishing sexual pleasure and, in turn, impacting the relationship and marriage. Regarding the urinary system, vaginal laxity can lead to stress urinary incontinence, such as involuntary leakage of urine due to increased abdominal pressure from coughing or sneezing. This is because vaginal laxity weakens the supporting structures of the urethra. Regarding the reproductive system, vaginal laxity can prevent the vaginal wall from adhering tightly, making it more susceptible to bacterial infection, leading to gynecological conditions such as vaginitis, and can also cause pelvic organ prolapse.

[0032] For such patients, the present disclosure proposes an implantable kit for vaginal tightening, which is fixed on the pelvis 180 . Specifically, the first implantable device 110 is fixed on the left side of the pelvis 180 , and the second implantable device 120 is fixed on the left side of the pelvis 180 .

[0033] Thus, the first implantable device 110 and the second implantable device 120 can fix the vagina 44 respectively, and the combination of the two can reduce the inferior angle of the pubic symphysis 150 to further squeeze the vagina 44.

[0034] The width and shape of the inferior angle of the pubic symphysis affects the attachment and contraction force of the pelvic floor muscles, which in turn affects the firmness of the vagina. Under normal circumstances, the inferior angle of the pubic symphysis is approximately 60°-70° for men and approximately 70°-85° for women. During childbirth, changes in hormone levels and the passage of the fetus through the birth canal can cause a certain amount of pressure and damage to the pelvic floor muscles and ligaments, leading to relaxation of the pelvic floor muscles and, in turn, vaginal relaxation. In addition, with aging, changes in hormone levels in the body, especially decreased estrogen secretion, can also lead to a decrease in the elasticity of tissues such as the ligaments and pelvic floor muscles around the inferior angle of the pubic symphysis, further affecting the firmness of the vagina. This design can reduce the inferior angle of the pubic symphysis through an implantable kit, thereby better constricting the vagina.

[0035] The implantable device of the present disclosure may be Figure 1 Any implantable device in the implantable kit shown below. Figures 2 to 4b Further explanation of implantable devices.

[0036] Figure 2 FIG is a schematic diagram of components of an implantable device for vaginal tightening according to one embodiment of the present disclosure. Figure 2 As shown, the implantable device for vaginal tightening may include a fixing bracket 20 and a cystic member 30 , and the fixing bracket 20 may be sealingly coupled with the cystic member 30 such that a filling cavity 60 is formed therein.

[0037] Specifically, Figure 3a and Figure 3b 1 is an oblique view and a side view of a fixing bracket in an implantable device for vaginal tightening according to an embodiment of the present disclosure. Figure 3a As shown, the fixing bracket 20 has a groove 21 .

[0038] Figure 4a and Figure 4b 1 is an external view and an internal view of a cystic member in an implantable device for pelvic floor support according to an embodiment of the present disclosure. Figure 4a As shown, the bladder member 30 has a collapsible cavity 32 .

[0039] Reference Figure 2 When the cystic member 30 is sealedly coupled to the fixing bracket 20, the cavity 32 of the cystic member 30 can cooperate with the groove 21 of the fixing bracket 20 to form a filling cavity 60. Accordingly, when a fluid substance is injected into the filling cavity 60, the filling cavity 60 can expand to compress the vaginal wall.

[0040] In one example, the flowing substance injected into the filling cavity 60 may include a substance with high fluidity, such as liquid and gas. For example, the flowing substance may include a fluid such as silica gel.

[0041] In another example, the cystic member 30 can be made of a material with an elastic modulus that is adaptive, allowing it to automatically adjust its shape when subjected to pressure. For example, compared to the fixed stent 20, the cystic member 30 can be made of a more flexible material with greater elasticity, such as silicone and / or silica gel. This design utilizes improved materials that, through biomechanical manipulation, provide both controllable fluidity and good load-bearing capacity, thereby addressing the stress concentration issues associated with traditional implants.

[0042] In another example, the expansion displacement of the cystic member 30 can be adjusted by controlling the amount of fluid injected into the filling cavity 60. This design can provide an expansion displacement suitable for each patient according to their actual conditions, and the cystic member 30 can squeeze the vaginal wall to an appropriate degree, thereby achieving a better vaginal contraction effect.

[0043] In another example, the surface of the cystic member 30 is treated for biocompatibility, thereby reducing adverse reactions caused by contact with organ tissues. Furthermore, the surface of the cystic member 30 can also be roughened, thereby playing a stronger limiting role.

[0044] The following will refer to Figure 4a and Figure 4b The following describes in detail the cystic member 30 in the implantable device according to one embodiment of the present disclosure. In this embodiment, the cystic member 30 connects two symmetrical drum surfaces 34 via a positioning arc surface 33 to form a cavity 32, and the cystic member 30 is detachably coupled to the fixing bracket 20 via a fitting surface 31 opposite to the positioning arc surface 33.

[0045] You can understand. Figure 4a and Figure 4b The cystic member 30 is only schematic. In fact, the shape of the cystic member 30 can be set according to actual conditions. For example, the cystic member 30 can be formed by combining one or more surfaces, and is not limited to the following. Figure 4a and Figure 4b The cystic member 30 shown in FIG includes three surfaces. Alternatively, the cystic member 30 can be designed to be more rounded to avoid sharp angles between the connecting surfaces. Furthermore, the cystic member 30 can be customized to have different shapes based on the patient's needs. For example, the cystic member 30 can be customized to have a wavy or pleated shape, so that the vagina can deform with the compression of the implantable device, thereby meeting more patient needs.

[0046] On the other hand, considering that the cystic member 30 is fixed to the fixing bracket 20, the shape of the cystic member 30 must also match the shape of the fixing bracket 20. For example, when the shape of the fixing bracket 20 is a customized streamlined shape, the shape of the cystic member 30 is also set to a corresponding streamlined shape accordingly; and corresponding to the fixing brackets 20 of different sizes, the cystic member 30 also has multiple matching sizes, so that it can better seal with the fixing bracket 20.

[0047] Accordingly, the shape of the entire implantable device can also be designed according to actual needs, and can be, for example, rod-shaped, banana-shaped, etc., with a certain curvature at both ends to fit the bone to be installed.

[0048] In another example, the implantable device may further include a filling hole 22 provided on the fixing bracket 20 or the cystic member 30, so that a fluid substance can be injected into the filling cavity 60 through the filling hole 22. After the fluid substance is injected, the filling hole 22 is sealed by a sealing member corresponding to the filling hole 22. Specifically, an appropriate amount of fluid substance can be filled into the implantable device through the filling hole 22 before or after installation.

[0049] In another example, the fixing bracket 20 may be further provided with fixing holes to cooperate with bone screws to fix the implantable device on the pelvis. Figure 3a As shown, the two ends of the fixing bracket 20 may be provided with a first fixing hole 23 and a second fixing hole 24, and referring back to FIG. Figure 1 The implantable device can be fixed to the patient's pelvis 180 by using bone screws in conjunction with the first fixing hole 23 and the second fixing hole 24. In the case of an implantable kit, two implantable devices can be fixed to both sides of the pelvis 180, thereby narrowing the inferior angle of the pubic symphysis 150 therebetween and squeezing the vagina 44 therebetween.

[0050] You can understand. Figure 3a The position of the fixing hole is only for illustration. In practice, two or more fixing holes may be provided at appropriate positions on the fixing bracket 20 according to actual needs to fix the implantable device on the pelvis 180 .

[0051] Figure 5 is a schematic diagram of a bone screw in an implantable device for vaginal tightening according to one embodiment of the present disclosure.

[0052] The bone screws used in the present disclosure may include HA type (cortical bone screws) and HB type (cancellous bone screws). Among them, the HA type bone screw has a thinner thread and a smaller pitch, and is usually a full thread design, which is suitable for grasping cortical bone, can provide stronger tensile strength and stability, and is commonly used in parts that withstand greater stress, and is therefore applicable to areas where cortical bone is thicker. The HB type bone screw has a thicker thread and a larger pitch, and is usually a partial thread or a sparse thread design, which is suitable for grasping cancellous bone, can better embed in cancellous bone, provide good holding power, and is commonly used in parts with more cancellous bone. In addition, the material of the bone screw can, for example, be titanium alloy, and the length range of the bone screw can, for example, be between 15mm and 50mm.

[0053] In a further non-limiting example, the bone screws used in the present disclosure may be one or more of HA 3.5mm bone screws (i.e., bone screws with a diameter of 3.5mm), HB 3.5mm, or HB 4.0mm bone screws (i.e., bone screws with diameters of 3.5mm and 4.0mm, respectively). Furthermore, both types of screws may be used with a T15 / SW2.5 driver and a 2.5mm drill bit.

[0054] It can be appreciated that, depending on the patient's pelvic condition and the positions of the fixation holes on the implantable device, two or more appropriate bone screws can be selected to effectively fix the implantable device on the pelvis.

[0055] In one non-limiting example, referring to Figure 3a The filling hole 22 can be set at the end of the fixing bracket 20 close to the pubic bone 41 of the pelvis, such as Figure 1 In addition, the filling through hole 22 can be provided on the side of the groove 21 of the fixing bracket 20, that is, the side facing the patient's skin when the fixing bracket 20 is installed in the patient's body.

[0056] This design makes it easy to inject the filling cavity 60 through the filling hole 22 after the implantable device is fixed on the pelvis, thereby adjusting the expansion displacement of the cystic member 30 by controlling the amount of flowing material injected into the filling cavity 60, and further adjusting the degree of compression of the implantable device on the vaginal wall.

[0057] Specifically, for example, during the initial surgery, the fixing bracket 20 can be fixed to the pelvis 180, and then a fluid substance can be injected through the filling hole 22. The internal pressure of the cystic member 30 is monitored in real time. When the internal pressure reaches a specified value, the injection is stopped, and then the filling hole 22 is sealed with a sealing member such as a screw. The specified value can be pre-set and depends on the actual situation of each patient, such as the desired degree of vaginal compression or the desired expansion displacement of the cystic member.

[0058] When the first surgical treatment is needed to be adjusted, the amount of the flowable substance can be adjusted again through the filling hole 22, so as to adjust the degree of extrusion to the vaginal wall, without the need of complicated operations such as disassembling and replacing the implantable device, thereby reducing the difficulty and cost of the operation, reducing the trauma and pain of the patient, reducing the risk of postoperative complications, etc.

[0059] It can be appreciated that, Figure 3a The position of the filling hole 22 in the middle is only illustrative, and in fact, the filling hole 22 can be arranged at a suitable position on the fixed support 20 or the cystic member 30 according to actual needs. For example, the filling hole can also be arranged on the cystic member 30, and correspondingly, the injection or infusion can be performed through the filling hole by the infusion tube.

[0060] Referring back to Figure 2 , another embodiment of the implantable device according to the present disclosure is given below. In this embodiment, the cystic member 30 is also detachable from the fixed support 20, for example, the cystic member 30 and the fixed support 20 can be provided with cooperating connectors such as buckles, so that the coupling and disassembly can be facilitated.

[0061] In this embodiment, the cystic member 30 is not in the shape with an opening as shown in Figure 4a and Figure 4b , but is a hollow capsule that is a sealed structure itself, in other words, the cystic member 30 has a sealed cavity 32. When the cystic member 30 is coupled with the fixed support 20, the cystic member 30 can be partially embedded in the groove 21 of the fixed support 20. In this case, the filling cavity 60 of the implantable device is the cavity 32 of the cystic member 30. Correspondingly, the injection of the flowable substance into the filling cavity 60 can be performed by injecting into the sealed cavity 32 of the cystic member 30 through the filling hole 22 on the cystic member 30, and the fixed support 20 can not be provided with the filling hole.

[0062] This design makes it possible to only disassemble and remove the cystic member 30 from the implantable device when the implantable device needs to be replaced after being fixed in the patient's body, without the need to remove the fixed support 20 that has been fixed to the bone from the patient's body. Correspondingly, the updated cystic member 30 can be fixed to the original fixed support 20 through the connectors such as buckles. Further, the injection of the flowable substance into the sealed cavity 32 of the updated cystic member 30 through the filling hole 22 on the updated cystic member 30 can make the filling cavity 60 expand, that is, the updated cystic member 30 expands out of the outer surface of the fixed support 20 to extrude the vaginal wall.

[0063] This simplified replacement operation can reduce the difficulty and cost of the operation, reduce the trauma and pain of the patient, and reduce the risk of postoperative complications, etc.

[0064] The above describes the implantable device and implantable kit for vaginal tightening disclosed herein. This disclosure provides an implantable device comprising a composite fixation bracket and cystic member. Installing the implantable device disclosed herein on the female pelvic floor can provide appropriate fixation and compression, thereby improving vaginal laxity caused by childbirth and other factors, thereby enhancing a woman's quality of life.

[0065] Several techniques are currently available for vaginal contraction:

[0066] (1) Kegel exercises, which allow patients to voluntarily contract and relax the pelvic floor muscles, such as Kegel exercises, to enhance the support of the pelvic floor muscles. However, the disadvantage is that the effect is slow and requires long-term persistence. Many patients have poor compliance, and the effect is not obvious for women with muscle strength levels of 0-1. If the exercise method is wrong, it may be counterproductive.

[0067] (2) Biofeedback electrical stimulation therapy, which uses electronic equipment to convert the activity of the pelvic floor muscles into sound and light signals to assist training. The electrical stimulator stimulates the muscles to produce rhythmic contractions and promote functional recovery. However, the current intensity is limited. Too strong current will stimulate pain, and the treatment effect depends largely on the performance of the equipment and the technical level of the operator.

[0068] (3) Laser treatment, which uses laser to stimulate collagen remodeling to enhance the elasticity and firmness of the vaginal wall. However, the duration of the therapeutic effect is uncertain and multiple treatments may be required. Improper operation or excessive energy may pose risks.

[0069] (4) Traditional vaginal tightening surgery involves removing excess tissue from the posterior vaginal mucosa and muscularis and then suturing and repairing it to reduce the volume of the vagina and tighten the vagina. However, there may be risks such as scar formation and pain during intercourse after the surgery.

[0070] It can be seen that the above-mentioned existing technologies all have certain defects, such as poor effect, pain, and many sequelae. Compared with the above-mentioned existing technologies, the present disclosure has at least the following advantages due to the design of an integrated implant device and kit that fixes the stent and the cystic member:

[0071] (1) Better therapeutic effect. The implant device and kit disclosed herein combine a relatively rigid fixed support with a flexible cystic member and fill it with a fluidic substance, thereby controlling the arcuate expansion displacement of the cystic member and appropriately squeezing and limiting the vaginal wall to achieve a more effective effect of improving vaginal relaxation.

[0072] (2) Implantation is less difficult and less expensive. The implantation device and kit disclosed herein only require simple puncture and fixation operations, and the material cost of the implantation device and kit is low. Therefore, the implantation is less difficult, easier to replace, and less expensive.

[0073] (3) The implant device and kit disclosed herein have fewer side effects. The materials of the implant device and kit disclosed herein are relatively soft and more ergonomic, making it less likely for patients to experience discomfort such as a foreign body sensation or pain, or to experience side effects such as local tissue compression and damage.

[0074] It can be understood from this that the implant device and kit for vaginal tightening disclosed herein have strong practical significance.

[0075] What has been described above includes examples of various aspects of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one skilled in the art will recognize that many further combinations and permutations of the claimed subject matter are possible. Thus, the disclosed subject matter is intended to embrace all such alterations, modifications, and variations that fall within the spirit and scope of the appended claims.
