Description

Technical Field

[0001] The present invention relates to the technical field of postoperative hemostasis, and more specifically, to a postoperative hemostasis device for urethral surgery through a vaginal incision. Background Art

[0002] In the clinical treatment of female stress urinary incontinence, mid-urethral suspension has become the most widely used mainstream surgical procedure, mainly including retropubic tension-free mid-urethral suspension and transobturator tension-free mid-urethral suspension. This surgical operation is accurately positioned in the mid-urethra. Through a small incision of about 1 cm made in the anterior vaginal wall, a non-absorbable patch with a length of about 15 cm is implanted. Since this surgical procedure does not require penetration of the skin, it greatly reduces the patient's pain perception after surgery and significantly accelerates the rehabilitation process. It is one of the most minimally invasive surgical methods currently.

[0003] If the patient also has pelvic organ prolapse, usually on the basis of performing vaginal suspension, additional urethral suspension is required. However, there are problems that cannot be ignored in the postoperative care stage of this surgery. After the urethral suspension is completed, a surgical incision of about 1.5 cm long will be formed near the external orifice of the female vagina. Subsequently, this incision needs to be carefully sutured. To achieve the expected effect of compressive hemostasis, gauze is generally packed in the vagina. However, in actual clinical operations, the surface texture of the gauze commonly used for packing is relatively rough. During the process of removing and replacing the gauze, it is extremely easy to cause intense friction with the wound, which not only brings a very significant pain experience to the patient, improper operation will affect wound healing, and the retained gauze also greatly increases the potential risk of wound infection.

[0004] In addition, if the gauze packed in the vagina is excessive, it will cause vaginal obstruction. As an organ with natural secretion function, the vagina usually continuously secretes body fluids. Once the vagina is blocked by gauze, the secretions in the vagina cannot be discharged normally and accumulate in the body for a long time, which will undoubtedly create extremely favorable conditions for infection at the wound site and further threaten the patient's postoperative rehabilitation. Summary of the Invention

[0005] In the prior art, gauze packing is mostly used after transvaginal surgery. When removing and replacing the gauze, it will frictionally stimulate the wound, affect wound healing, and the retained gauze is likely to cause infection, thus causing secondary injury. The purpose of the present invention is to provide a postoperative hemostasis device for urethral surgery through a vaginal incision.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] In the above solution, when the device is used, first place it into the patient's vagina, connect it to an external air supply hose through the first threaded joint, inflate the corrugated expansion balloon to make it expand and push the top pressure balloon to reach the wound. Then connect the air pipeline to the second threaded joint to supply air to the pressure balloon to make it expand. Rotate the balloon group to make the antibacterial pad outside the pressure balloon fit the wound to complete the dressing. The first one-way valve and the second one-way valve ensure one-way ventilation of the threaded interface to achieve good sealing. After the wound heals, unscrew the second one-way valve, and the pressure balloon shrinks, facilitating the extraction of the device, effectively avoiding the adverse effects of the oil gauze on the vagina and the wound, and providing a safe and effective method for the preliminary treatment and later removal of the surgical wound.

[0020] The balloon group and the wearing mechanism are closely matched, which can improve the practicability of the device. After placing the balloon group in the vagina and completing the air supply, the belt can be pulled to adjust.

The bottom of the connecting block 33 penetrates through the mounting hole 2. A first threaded joint 37 and a second threaded joint 38 are respectively installed on both sides of the bottom of the connecting block 33. The top of the first threaded joint 37 is communicated with the inside of the corrugated telescopic balloon 34. The top of the second threaded joint 38 is communicated with the inside of the pressure balloon 35. By providing the mounting hole 2, the carrier 1 provides a stable mounting foundation for the balloon group 3, ensures the stable position of the balloon group 3 in the body, and guarantees the effective exertion of its functions. In the balloon group 3, the magnetic connection mode between the first magnetic ring 31 and the second magnetic ring 32 not only facilitates the quick installation and disassembly of the balloon group 3 but also ensures the tightness of the connection to a certain extent. The connecting block 33 is connected to the second magnetic ring 32, which not only stabilizes the corrugated telescopic balloon 34 and the pressure balloon 35 but also realizes the independent air supply control of the corrugated telescopic balloon 34 and the pressure balloon 35 respectively through the first and second threaded joints 38 on both sides of the bottom, providing convenience for precisely adjusting the balloon state. The antibacterial pad 36 outside the pressure balloon 35 can effectively care for the wound. The wearing mechanism 4 fixedly installed on the outside of the carrier 1 cooperates with the balloon group 3. As mentioned before, it can be flexibly adjusted according to the patient's body type to ensure the stable wearing of the whole device in the patient's body.

[0050] Please refer to Figures 1 - 7, a first one-way valve 39 is threadedly connected to the bottom of the first threaded joint 37, a second one-way valve 310 is threadedly connected to the bottom of the second threaded joint 38, threaded interfaces 311 are provided at the bottoms of the first one-way valve 39 and the second one-way valve 310, the balloon group 3 further includes an elastic drainage tube 312, the elastic drainage tube 312 is fixedly connected to the middle of the connecting block 33, the bottom of the elastic drainage tube 312 penetrates through the connecting block 33, the top of the elastic drainage tube 312 penetrates through the corrugated expansion balloon 34 and the pressure balloon 35, the material of the elastic drainage tube 312 is the same as that of the pressure balloon 35, a sealing screw cap 313 is threadedly connected to the bottom of the elastic drainage tube 312 that penetrates through the connecting block 33, a liquid guide groove 314 is formed at the top of the pressure balloon 35, and the bottom of the liquid guide groove 314 is communicated with the top of the elastic drainage tube 312. The first one-way valve 39 threadedly connected to the bottom of the first threaded joint 37 and the second one-way valve 310 threadedly connected to the bottom of the second threaded joint 38, together with the threaded interfaces 311 at their bottoms, enable gas to only flow into the corrugated expansion balloon 34 and the pressure balloon 35 unidirectionally, greatly improving the sealing performance and safety during the balloon inflation process, preventing gas leakage from affecting the normal operation of the balloon and the hemostatic effect of compressing the wound.

The limiting rod 46 is inserted into the interior of one of the limiting holes 44. A limiting ball 47 is fixedly connected to the outer end of the limiting rod 46. The waistband 43 is also an elastic band. The annular elastic band 41 is integrally oval-shaped. The annular elastic band 41 is oval-shaped, which fits the physiological structure of the human body. At the same time, it can reserve space for the patient's anus, so that the device does not need to be removed when the patient needs to defecate. And the space reserved between it and the carrier 1 can reserve an intubation position for the urethral catheter, which is convenient for assisting the patient to urinate and defecate. It is fixed to the middle parts of both sides of the carrier 1, providing stable circumferential support for the whole device. The elastic connecting band 42 connected to its outer side and the waistband 43 which is also made of elastic band material greatly enhance the flexibility and adaptability of wearing, can meet the needs of patients with different body types, and ensure the wearing comfort. The limiting holes 44 equidistantly formed at one end of the outer surface of the waistband 43, in cooperation with the sleeve frame 45 fixedly connected to the other end, can accurately adjust the length and tightness of the waistband 43 by inserting the limiting rod 46 into different limiting holes 44. The limiting ball 47 at the outer end of the limiting rod 46 prevents the limiting rod 46 from accidentally coming out. The design of the wearing mechanism 4 ensures the stability of the device when the patient uses the compression balloon after the operation.

[0052] Please refer to Figures 8 - 11, the antibacterial pad 36 includes a base block 361 which is fixedly connected to one side of the outer surface of the pressure balloon 35. An elastic magic hook surface 362 is fixedly connected to the outside of the base block 361. An elastic magic loop surface 363 is bonded to the outside of the elastic magic hook surface 362.

It is connected to the water-absorbing and antibacterial layer 364 through the elastic magic hook surface 362 and the loop surface, which is convenient for replacement and can ensure close fitting with the pressure balloon 35 without easy displacement. In the water-absorbing and antibacterial layer 364, the environment-friendly liquid silicone layer 3641 is mixed with a quaternary ammonium salt antibacterial agent, the disinfected cotton layer 3642 contains an iodophor solution, and the superfine fiber layer 3643 is coated with a silver ion exchange resin layer. The three layers cooperate to achieve powerful water absorption and antibacterial functions. The antibacterial layer 365 is composed of a chitin fiber layer 3651, a bamboo fiber layer 3652 and an oil gauze 3653, which play their respective antibacterial and protective characteristics. In addition, the silver ion antibacterial layers on the outer surfaces of the corrugated expansion balloon 34 and the pressure balloon 35 further enhance the overall antibacterial ability. Multiple antibacterial mechanisms complement each other to provide protection for the wound after urethral surgery in all directions and ensure the smooth progress of the recovery process.

[0053] The specific working process of the technical solution provided by this application is as follows:

[0054] Place the device into the patient's vagina. First, connect it to the external air supply hose through the first threaded joint 37 and inflate the corrugated expandable balloon 34. As the gas is filled, the corrugated expandable balloon 34 expands, pushing the pressure balloon 35 at the top to move upward in the vagina until it reaches the wound in the patient's vagina. Then, connect the air pipeline to the second threaded joint 38 to supply gas to the pressure balloon 35 to expand and stretch it. At this time, rotate the balloon group 3 to make the antibacterial pad 36 on the outer surface of the pressure balloon 35 closely fit the wound, completing the filling and dressing of the wound. The settings of the first one-way valve 39 and the second one-way valve 310 ensure that only one-way gas flow can occur at the first threaded interface 311 and the second threaded interface 311, achieving a good sealing effect. When the wound has healed, unscrew the second one-way valve 310, and the gas in the pressure balloon 35 is squeezed out and shrinks. At this time, the device can be smoothly withdrawn from the vaginal orifice, effectively avoiding the friction of the oil gauze 3653 against the vagina and preventing discomfort to the vagina and secondary injury to the wound.

[0055] The coordinated cooperation between the balloon group 3 and the wearing mechanism 4 further improves the functionality of the device. After placing the balloon group 3 in the patient's vagina and completing the air supply installation, it can be adjusted by pulling the belt 43. Since the belt 43, the elastic connecting belt 42, and the annular elastic belt 41 are all elastic and can adapt to the body types of different patients. Insert one end of the belt 43 into the sleeve frame 45, and then insert the limiting rod 46 and the limiting ball 47 at its end into the limiting hole 44. By using the mutual limiting effect between the limiting rod 46 and the limiting hole 44, the tightness of the elastic connecting belt 42 can be flexibly adjusted, thus realizing the stable wearing of the device. By inserting the limiting rod 46 into different limiting holes 44, the tightness of the belt 43 can be further accurately adjusted, significantly improving the convenience of use. In addition, a liquid guide groove 314 is provided at the top of the pressure balloon 35, and the body fluid in the vagina can be discharged through the liquid guide groove 314 and the elastic drain pipe 312. During use, regularly unscrew the sealing screw cap 313 to timely discharge the human secretion mucus in the vagina, which not only improves the overall convenience of use of the device but also helps promote the recovery of the wound.

[0056] The bonding design of the elastic hook surface 362 of the magic tape and the elastic loop surface 363 of the magic tape provides convenience for the replacement of the antibacterial pad 36. If it is necessary to replace the antibacterial pad 36, just take out the device and tear off the elastic hook surface 362 of the magic tape and the elastic loop surface 363 of the magic tape, and the operation can be quickly completed. The water-absorbing antibacterial layer 364 is connected to the outside of the elastic loop surface 363 of the magic tape. Each part performs its own functions. The environmentally friendly liquid silicone layer 3641 is mixed with quaternary ammonium salt antibacterial agents, which can not only prevent external liquids from invading the inside of the antibacterial pad 36 and play an isolation and protection role for the wound, but also have antibacterial ability; the disinfected cotton layer 3642 on its outside contains an iodine tincture solution, which can absorb the wound exudate and use iodine tincture for sterilization and disinfection while absorbing the wound exudate; the ultra-fine fiber layer 3643 on the outside of the disinfected cotton layer 3642 has a silver ion exchange resin layer coated on its surface, which further enhances the water absorption effect and continuously exerts an antibacterial effect through the silver ion exchange resin. The antibacterial layer 365 connected to the outside of the ultra-fine fiber layer 3643, the innermost oil gauze 3653 fits the wound, prevents adhesion and has a certain antibacterial property; the bamboo fiber layer 3652 on its outside assists in antibacterial; the outermost chitin fiber layer 3651 further inhibits the growth of bacteria. At the same time, the silver ion antibacterial layer coated on the outer surfaces of the corrugated expansion balloon 34 and the pressure balloon 35 strengthens the antibacterial effect as a whole. The structures of each layer cooperate with each other to realize functions such as support, fitting adjustment, water absorption, antibacterial, and adhesion prevention, providing a strong guarantee for the care and recovery of the urethral surgical wound in all aspects. Specifically, the bonding design of the elastic hook surface 362 of the magic tape and the elastic loop surface 363 of the magic tape allows different antibacterial pads 36 to be replaced during application. Specifically, the antibacterial pad 36 can also use alginate dressings, which are natural polysaccharide substances extracted from seaweeds. They can absorb a large amount of wound exudate, keep the wound moderately moist, and are beneficial to wound healing. After contacting the wound exudate, they can quickly form a gel, which can effectively stop bleeding, create a good environment for wound healing, have good biocompatibility, can reduce the risk of wound infection, promote cell growth and tissue repair, and can promote the autolysis of necrotic tissue on the wound surface through gelation, accelerating the wound healing process. It is suitable for wounds with moderate to large amounts of exudate inside the vagina, such as lateral incisions, lacerations with more bleeding and exudate, etc.;Chitosan dressings can also be used. It is a natural polymer polysaccharide obtained by the deacetylation of chitin, which has an inhibitory effect on a variety of bacteria and fungi, can effectively prevent vaginal wound infections. For example, it has a significant inhibitory effect on common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus. It can promote cell proliferation and tissue regeneration, accelerate the healing of vaginal wounds, shorten the healing time, activate the coagulation system, stop bleeding quickly, reduce the wound bleeding time and blood loss volume, can be gradually degraded in the body without residue, and is harmless to the human body. It is suitable for vaginal postoperative wounds, ulcers, etc., especially in cases where the risk of infection is relatively high, such as vaginal damage caused by inflammation. Hydrocolloid dressings can also be used. It is a hydrophilic colloid composed of sodium carboxymethylcellulose, gelatin, pectin, etc., which can form a closed moist environment, prevent external bacteria from invading, reduce the infection probability, and at the same time maintain the local temperature of the wound, which is beneficial to wound healing. It has good flexibility and adhesiveness, can fit well with the irregular wound surface inside the vagina and is not easy to fall off. Patients feel more comfortable when using it. It can absorb a certain amount of wound exudate and form a gel to keep the wound moist without soaking the surrounding tissues, which helps to form a microenvironment conducive to healing on the wound surface, promote fibrinolytic activity, and accelerate wound healing. It is suitable for superficial wounds inside the vagina and wounds with a small amount of exudate, such as mild abrasions, small wound surfaces after laser treatment, etc. The specific type of dressing can be determined by the doctor according to the actual clinical needs, and the dressing on this device can be replaced as needed.;
