Description

Technical Field

[0001] This invention relates to a gynecological medical device, and more particularly to a vaginal mold for recovery after radical hysterectomy combined with vaginal lengthening surgery, and a method for manufacturing the mold. Background Technology

[0002] In existing technologies, vaginal molds are commonly used after vaginal surgery to maintain the vaginal condition. For example, the applicant applied for an invention patent in 2016 with patent number 201611184990.4, entitled "A Vaginal Mold for Recovery." This patent mainly improves the convenience and comfort of the vaginal mold, while also enhancing its cleanliness and reducing the possibility of infection during use. This patent has been granted, and the product has been launched on the market with good results. However, during the promotion and use process, we found that this structure could also be used for continuous intravaginal medication delivery or wound compression for hemostasis. Previous patents mentioned a technical solution using medication within the mold to assist wound healing. However, the medication flows within the vaginal environment and cannot accumulate near the wound, making it difficult to achieve the desired effect.

[0003] For example, common treatments for cervical cancer include radical hysterectomy and radiotherapy. During surgery, 2-4 cm of vaginal wall and parametrial tissue is typically removed, which is closely related to vaginal shortening. To improve the patient's quality of life, vaginal lengthening surgery is often performed after hysterectomy. Post-operatively, the incision from radical hysterectomy and vaginal lengthening requires protection and support. Simply using a rigid lengthening mold can cause excessive pressure, affecting local blood supply and leading to ischemia and necrosis of the lengthened portion due to excessive pressure. However, using flexible materials may be insufficient to provide continuous support without damaging the vaginal wall, affecting the surgical outcome, causing contracture of the lengthened portion, and damaging the surgical site.

[0004] Compression hemostasis is a method of stopping bleeding by applying continuous pressure to the wound, which is very effective for visible wounds. Current techniques allow for surgical suturing of prominent wounds on the vaginal wall near the vaginal opening, resulting in good healing outcomes. However, it is difficult to manage deeper wounds that are not easily observed. Summary of the Invention

[0005] This invention provides a vaginal mold for recovery after radical hysterectomy combined with vaginal lengthening surgery, solving the problem in the prior art that it is impossible to stably and continuously apply drugs or compress deep wounds in the vagina to stop bleeding.

[0006] To achieve the aforementioned technical solution, the present invention provides a vaginal reconstruction and rehabilitation support mold for cervical cancer radical surgery combined with vaginal lengthening, comprising a mold body, which is a hollow cylindrical tube that extends into the vagina to maintain the vaginal wall in an open state. The cylindrical tube includes a support portion with a hemispherical top, and a first through hole is opened above the support portion, the first through hole being located on the side close to the surgical wound. A push block is provided in the cylindrical tube, the top of the push block and a semi-permeable membrane forming a space, an agar block is provided in the space, a second through hole is opened on the top of the push block, a liquid bladder is provided in the push block, the liquid bladder being connected to the agar block through the second through hole; a push block limiting device is provided on the inner wall of the cylindrical tube.

[0007] Preferably, the support portion is composed of two parts joined together, with the first through hole located on one of the parts. This structure allows for the replacement of components of the mold body as needed, ensuring that the first through hole is aligned with the wound as much as possible.

[0008] Preferably, the inner edge of the first through-hole has an annular groove, and a resin ring is nested within the annular groove. The side of the resin ring that contacts the semi-permeable membrane is polished. The resin ring structure reduces the friction between the semi-permeable membrane and the mold during use, allowing it to smoothly wrap around the agar block, pass through the first through-hole, and support it at the wound site.

[0009] Preferably, the inner side of the support portion is provided with an annular positioning groove, and the lower edge of the semipermeable membrane is fixed in the annular positioning groove by a fastener. This facilitates the replacement of the semipermeable membrane and ensures a secure fixation.

[0010] Preferably, the support is connected to the push block via a threaded connection. This structure provides sufficient stability and prevents the support from detaching during the pushing of the agar block.

[0011] Preferably, the agar block is shaped to match the inner side of the support portion, and is a hemispherical shape of 5-12 cubic centimeters. This hemispherical agar block is sufficient to provide support at the vaginal wound site.

[0012] This invention also includes a method for preparing a vaginal reconstruction and rehabilitation support mold after radical hysterectomy combined with vaginal lengthening, comprising the following steps:

[0013] Measure vaginal dimensions and locate the postoperative incision site.

[0014] Select a support with an appropriate size and structure based on vaginal size and postoperative wound location;

[0015] The first through-hole was made at the top of the support structure, closest to the postoperative wound.

[0016] A semi-permeable membrane is fixed inside the support section.

[0017] Prepare the drug and agar blocks, place the agar blocks on the top of the pusher block, and push the pusher block with the agar blocks into the support part. The preparation is complete.

[0018] Preferably, the medication used during the initial use of the vaginal mold is directly adsorbed onto the surface of the agar block, and subsequent medications are added to the agar block through the liquid sac within the pusher. The agar block has unique gelling properties, readily absorbing the medication without reacting with it. Therefore, it can fully absorb a significant amount of medication before use, and during application, it can effectively penetrate the wound.

[0019] The present invention includes the following steps during use: First, the mold is placed inside the vagina, at which time the agar block is stored in the support part; when the mold is pushed to the designated position, the pushing of the mold is stopped and the pusher is pushed. Under the action of the pusher, the agar block wrapped in the semi-permeable membrane is squeezed out from the first through hole. The first through hole is closest to the postoperative wound position, so the pushed agar block can fully contact the wound and apply a certain pressure to the wound. At this time, the pusher is rotated and the pusher is fixed by the locking structure. At this time, it is ensured that the agar block is fully and continuously pressed on the wound.

[0020] By adopting the above technical solution, the present invention has the following advantages: The mold body provides overall support, and the ejectable agar block is used to accurately position the wound, providing stable and non-compressive flexible support for the vagina after radical hysterectomy combined with vaginal lengthening. Continuous medication is also applied to the surgical wound; even if bleeding occurs, pressure can be applied to stop the bleeding and accelerate healing. Compared with existing techniques that rely solely on suturing the wound, the present invention offers improved convenience and accuracy. In this process, the soft agar block, encased in a semi-permeable membrane, contacts the wound instead of the rigid mold body, reducing irritation and effectively alleviating patient pain.

[0021] It is important to note that this invention focuses on postoperative recovery after radical hysterectomy combined with vaginal lengthening. Because the wound location after this procedure is relatively fixed and easy to locate, it is widely used in this scenario. Furthermore, due to the good extensibility of the agar block, it can cover a large area, allowing for medication application and effective pressure hemostasis even in cases of deep vaginal bleeding where the wound location cannot be accurately located.

[0026] Figure 4 This is a schematic diagram of a set of molds of different lengths used in the present invention for vaginal reconstruction and rehabilitation support molds after radical hysterectomy combined with vaginal lengthening. Detailed Implementation

[0027] In modern gynecological practice, we have encountered many cases of vaginal injuries requiring hemostasis. Some wounds near the vaginal opening are relatively easy to manage, requiring only simple pressure hemostasis or suturing. However, for deeper wounds, existing technologies lack effective treatment methods. The applicant envisioned using the technical solution disclosed in a prior art patent (patent number 201611184990.4), entitled "A Vaginal Mold for Recovery," to achieve pressure hemostasis. However, the prior art's effect lies in supporting the vagina; its overall structure does not directly contact the vaginal base, especially the cervix. In fact, to reduce discomfort, the vaginal mold needs to maintain a certain distance from the cervix, failing to achieve effective pressure hemostasis.

[0028] In response, the applicant made further improvements based on prior patents. For example... Figure 1 , Figure 2 The invention disclosed herein is a vaginal reconstruction and rehabilitation support mold for cervical cancer radical surgery combined with vaginal lengthening. It includes a mold body 1, which is a hollow cylindrical tube that extends into the vagina to maintain its open state. The cylindrical tube includes a hemispherical support portion 2 at its top, with a first through-hole 22 located near the surgical wound. A pusher block 3 is provided within the cylindrical tube, and the top of the pusher block 3 and a semi-permeable membrane 5 form a space containing an agar block 4. In this invention, the semi-permeable membrane 5 is typically made of bio-cellulose membrane fabric, specifically fibers produced by the natural fermentation of Acetobacter xylinum. This material is now widely used in high-end facial masks, possessing skin-like functions, allowing oxygen permeability while isolating bacteria, and can be used on wounds without causing infection. It has ultra-fine fibers and excellent absorbency, causing no foreign body sensation on the vaginal wall, and also has a certain lifting effect, accelerating wound healing. It has a strong water-retaining capacity, allowing the medication in the agar block 4 to fully contact the wound surface without rapid loss.

[0029] Agar block 4 is typically prepared using agarose, which has a uniform gel structure and a high water content—approximately 98% to 99%. Most importantly, agar itself contains no nutrients and will not react chemically with the medication due to its own nutrients. This avoids changes in the vaginal environment and prevents unexpected chemical reactions that could affect the treatment effect. Agar also has good coagulation properties, thus providing support at the final stage of application. The shape of agar block 4 matches the inner side of support part 2, being a hemispherical shape of 5-12 cubic centimeters. A certain volume and gel strength are required to achieve the desired pressing effect. For ease of illustration, agar block 4 is depicted as a cube in the diagram, but its actual shape is not specifically defined.

[0030] The pusher block 3 has a second through hole 31 at its top, and a liquid bladder is provided inside the pusher block 3. The liquid bladder is connected to the agar block 4 through the second through hole 31. A pusher block limiting device 6 is provided on the inner wall of the columnar tube. An annular groove is formed on the inner edge of the first through hole 22, and a resin ring 7 is nested in the annular groove. The side of the resin ring 7 that contacts the semi-permeable membrane 5 is polished to prevent the rough surface of the resin ring 7 from scratching the semi-permeable membrane 5. Figure 3 As shown, the inner side of the support portion 2 is provided with an annular positioning groove 23, and the lower edge of the semi-permeable membrane 5 is fixed in the annular positioning groove 23 by a fastener. The annular positioning groove 23 serves two purposes: firstly, it stores excess semi-permeable membrane 5, preventing insufficient area of ​​the semi-permeable membrane 5 during use, thus ensuring it can wrap the agar block 4; secondly, the annular positioning groove 23 reduces the space inside the support portion 2, effectively fixing the position of the agar block 4 and preventing it from rolling or tumbling inside the support portion 2. Figure 2 In the embodiment shown, the support 2 is composed of two parts joined together and fixed together by a retaining ring 21. The push block 3 is provided with threads or other locking devices to ensure that the position of the push block 3 can be locked after operation, so that it will not be displaced relative to the support 2, thus ensuring continuous pressure.

[0031] like Figure 4 As shown, the length and shape of the vagina vary from patient to patient. Therefore, hospitals usually need to prepare a set of support molds of different sizes as a precaution. For some complex cases, molds with special shapes can be customized by 3D printing based on the measured shape.

[0032] This invention also includes a method for preparing a vaginal reconstruction and rehabilitation support mold after radical hysterectomy combined with vaginal lengthening, comprising the following steps:

[0033] Measure vaginal dimensions and locate the postoperative incision site.

[0034] Select a support component of appropriate size and structure based on vaginal size and postoperative wound location;

[0035] A first through hole 22 is made at the top of the support part 2, closest to the postoperative wound.

[0036] A semi-permeable membrane 5 is fixed inside the support portion 2.

[0037] The drug is prepared and agar block 4 is made. Agar block 4 is placed on top of push block 3, and push block 3 with agar block 4 is pushed into support part 2. Preparation is complete. When the mold body 1 is used for the first time, the drug is directly adsorbed on the surface of agar block 4. Subsequent drug additions are added to agar block 4 through the liquid bladder in push block 3.

[0038] Example 1: Postoperative recovery after radical hysterectomy combined with vaginal lengthening surgery for cervical cancer.

[0039] Radical hysterectomy for cervical cancer typically involves removing the entire uterus and vaginal lengthening surgery, which uses the peritoneum or intestines to lengthen the vagina by 4-6 cm. In some cases, early postoperative support with rigid materials is unsuitable to avoid affecting local blood supply and causing excessive pressure, ischemia, and necrosis of the lengthened portion. However, using overly soft materials or failing to provide support early on can affect the surgical outcome, leading to contracture of the lengthened portion. Contracture can cause vaginal stenosis, resulting in difficulty with intercourse or obstructed menstrual flow. In such cases, the device described in this invention can be used for treatment. First, an endoscope is used to locate the wound, and a suitable support part 2 is selected based on the specific location of the wound. In this embodiment, the wound location after radical hysterectomy combined with vaginal lengthening is centered, so an integrated support part 2 is used, with the first through-hole 22 located at the top center of the support part 2, corresponding to the wound location. Appropriate medication is prepared for use. Before the first use, the direction of the support part 2 is adjusted to ensure that the first through-hole 22 is directly opposite the wound. An agar block 4 of the appropriate size is placed on top of the push block 3; generally, the volume of the agar block 4 should not be less than 9 cubic centimeters, otherwise the pressure effect will not be achieved later. If a pre-prepared reagent is available, soak the agar block 4 in the reagent before loading it in to ensure full absorption. Then, use tweezers to remove the agar block 4 and place it on top of the pusher block 3. The semi-permeable membrane 5 simply needs to be snapped into the annular positioning groove 23, so that as the agar block 4 is pushed outward, its outer side is automatically wrapped by the semi-permeable membrane 5.

[0040] During use, the mold body 1 is placed inside the vagina, with the agar block 4 stored within the support 2. Once the mold body 1 has reached the designated position, pushing the mold body 1 stops, and pushing the pusher 3 begins. Under the action of the pusher 3, the agar block 4, encased in the semi-permeable membrane 5, is squeezed out through the first through-hole 22. The agar block 4 has a certain degree of plasticity, so it will not break due to compression. Moreover, after being squeezed out of the first through-hole 22, its volume actually increases due to the absence of the support 2's constraint, ensuring coverage of the wound. In this embodiment, the wound is located centrally after radical hysterectomy combined with vaginal lengthening surgery. The first through-hole 22 is located closest to the postoperative wound position, allowing the pushed-out agar block 4 to fully contact the wound and apply a certain amount of pressure. The semi-permeable membrane 5 protects the medication within the agar block 4 during this process, preventing excessive loss of medication during squeezing. The agar block 4 itself is relatively soft, so this pressure on the wound will not cause significant pain. The strength of the agar block 4 itself ensures that the pressure is effective in stopping the bleeding. The user needs to use their sense of touch to ensure the agar block 4 is properly placed during operation, and also needs to make adjustments based on communication with the patient. After ensuring proper pressure, the push block 3 can be rotated. The push block 3 is locked in place by the locking device 32 inside the support 2, ensuring that the agar block 4 is fully and continuously pressed against the wound. The semi-permeable membrane 5 provides long-term, slow ion exchange, allowing the medication in the agar block 4 to be fully absorbed by the vaginal wall, thus achieving continuous medication and hemostasis. The columnar tube itself also helps prevent vaginal contracture.

[0041] To ensure cleanliness, the mold body 1 needs to be removed every 3 hours during actual use, and the wound healing status is assessed by observing vaginal discharge. This usually achieves hemostasis. If, after removing the mold body 1, observation reveals that hemostasis is still not achieved, further observation is needed to analyze whether the compression position is incorrect. In urgent situations, immediate surgery is required.

[0042] If the patient feels the contact area of ​​the agar block 4 gradually drying out during use, fluid can be injected into the liquid bladder inside the plunger 3 using a syringe. Under the pressure of the syringe, the medication is connected to the agar block 4 through the second through-hole 31 for rehydration. Normal saline or other medications suitable for the vaginal environment are usually injected here. This prevents the semi-permeable membrane 5 from adhering to the vaginal wall after the contact surface dries out. The liquid bladder, not marked in the diagram, is a sleeve placed inside the second through-hole 31 to prevent contamination of the plunger 3 during medication injection.

[0043] Example 2: Used for deep vaginal bleeding.

[0044] The female vagina has a certain depth. Wounds located 4-5 cm from the vaginal opening can be treated with simple surgical methods. However, wounds deep within the vagina are notoriously difficult to treat. Even simple wounds cannot be stopped with simple pressure. Existing techniques typically require only simple surgical suturing. This invention, however, eliminates the need for surgery, allowing hemostasis through pressure. An endoscope is used to locate the wound, and a suitable support portion 2 is selected based on its location. Since these wounds are usually on the vaginal wall, the support portion 2 is typically composed of two parts joined together. The first through-hole 22 is located on the part closest to the wound, and the two parts are secured by a retaining ring 21. The push block 3 has matching threads on its edge and the inner side of the support portion 2. Before first use, adjust the support portion 2 to ensure the first through-hole 22 is aligned with the wound. Place an agar block 4 of the appropriate size on top of the push block 3. Since the wound is located on the vaginal wall, close to the mold, a volume of 5-8 cubic centimeters for the agar block 4 is sufficient to achieve the desired pressure effect. If a pre-prepared reagent is available, directly immerse agar block 4 in it to ensure that the agar fully absorbs the reagent.

[0045] During use, the mold is placed inside the vagina, with the agar block 4 stored within the support portion 2. Once the mold reaches the designated position, stop pushing the mold and begin rotating the pusher block 3. The pusher block 3 rotates slowly along the threads, and under its action, the agar block 4, encased in the semi-permeable membrane 5, is squeezed out through the first through-hole 22. The first through-hole 22 is closest to the wound on the vaginal wall, ensuring that the pushed-out agar block 4 fully contacts the wound and applies pressure. At this point, stop rotating the pusher block 3, which is now fixed by the threads. Ensure that the agar block 4 is fully and continuously pressed against the wound. This achieves the effect of pressure hemostasis. In actual use, the main body needs to be removed every 3 hours, and the wound healing status is assessed by observing vaginal secretions. Hemostasis is usually achieved; if it fails to stop successfully, further observation or surgery is required.

[0046] If the patient experiences dryness at the contact point during use, fluid can be injected into the liquid sac inside the plunger 3 using a syringe. Under syringe pressure, the medication is connected to the agar block 4 through the second through-hole 31 for rehydration. Normal saline or other medications suitable for the vaginal environment are typically injected here. The liquid sac, not marked in the diagram, is a sleeve placed inside the second through-hole 31 to prevent contamination of the plunger 3 during medication injection.

[0047] Clinical trials have shown that the use of this invention can effectively improve the wound healing speed. Moreover, during the use of the mold, the mold body 1 does not directly contact the actual wound, thus avoiding secondary damage to the patient and reducing discomfort during use.

[0048] In addition to the preferred embodiments described above, there are other embodiments of the present invention. Those skilled in the art can make various changes and modifications based on the present invention, and all such changes and modifications should fall within the scope defined by the appended claims, as long as they do not depart from the spirit of the present invention.
