The problems of urine leakage and even urinary incontinence caused by trauma, nerve dysfunction, surgical complications, aging and the like are important reasons which seriously affect the life quality of patients and even cause diseases such as urinary tract infection and the like, and various technologies are developed to solve the problems at present, wherein the main solutions of the problems are divided into two types, namely (1) an operative treatment mode and (2) a non-operative treatment mode.

The surgical treatment method for moderate and severe urinary incontinence comprises two surgical treatment methods of urethral suspension and artificial urethral sphincter.

At present, the urethra suspension operation adopts the tension-free urethra suspension operation (TVT) mode and the trans-obturator urethra tension-free urethra suspension operation (TVT.O) mode clinically, the retropubic path has the mode from bottom to top and the top to bottom, and the obturator path has the mode from outside to inside and the mode from inside to outside. The urethra suspension operation is a minimally invasive operation improved based on the theory of a hammock, and synthetic materials are placed in the middle section of the urethra or the bladder neck, so that the supporting structure of the urethra is strengthened, and the effect of the hammock is achieved. After the tvt mesh belt puncture in the prior art is finished, the tvt mesh belt forms two free ends, the two free ends have no fixing action points, the mesh belt is fixed only by the friction force between barbs woven on the mesh belt and tissues, the function of adjusting the tightness in vitro is not provided, and when stress urinary incontinence recurs, the operation can be performed again only by selecting.

An Artificial Urinary Sphincter (AUS) treatment is recommended as the preferred option for treating severe stress incontinence in the EAU and AUA guidelines. The operation needs to connect the oversleeve, the liquid storage bag and the control pump which are respectively arranged in the body by using the connecting pipe, the operation difficulty is extremely high, the medical compliance is poor after long-term use, and a plurality of related complications still exist and the complete urine control state cannot be achieved. The prominent problems are mainly the recurrence of urinary incontinence after AUS implantation and complications such as erosion of the urethra by the cuff and infection. The recurrence of post-operative urinary incontinence is currently believed to be associated mainly with the occurrence of urethral atrophy, which occurs at the cuff site where the urethral atrophy is caused by the prolonged continuous mechanical compression of the cuff against the urethra and the tissues surrounding the urethra, thereby causing the recurrence of urinary incontinence; even the removal of the AUS device is necessarily caused by urinary erosion and infection, which are usually accompanied, and occur in close relation to urinary ischemia and urinary injury in the same site caused by prolonged continuous mechanical compression of the same site. Post-operative complications of AUS also include device failure, post-operative urinary retention, and the like.

Non-surgical solutions to urinary incontinence include pelvic floor muscle exercise, general treatment to control water intake and drinking time, medication, traditional chinese medicine treatment, and extracorporeal devices such as urine collectors or extra-penile clamps, which attempt to solve problems, such as solutions that clamp outside the shaft of the penis featuring penile clamp structures, openable structures, urethral compression structures, or urine collection structures. However, the clamping of the schemes on the penis body is easy to cause discomfort of human body, and the long-time use of the schemes can cause unsmooth blood supply to the penis, and the most critical problem is that the shape of the male penis is changed violently under the conditions of different time, different temperature and the like, so that the ideal installation and urine control effects of similar clamping structures are difficult to achieve.

In conclusion, the urethral suspension operation has the risk of recurrence of the urinary incontinence, and does not have the function of adjusting the tightness of the sling in vitro to control the urethral pressure; in the Artificial Urinary Sphincter (AUS) treatment modality, there is a risk of secondary surgery due to device failure, with some risk of post-operative complications; in non-operative treatment, the method for clamping the penis is obviously poor in applicability due to the physiological characteristics and side effects of men, and the above treatment methods have respective defects, so that the postoperative risk of recurrence is likely to occur, and the postoperative complication is frequently hidden.

The application provides a device of regulation and control urethra pressure can be used for medical equipment technical field, installs inside the human body, and the user can be in the device of regulation and control urethra pressure of this application of external operation. Referring to fig. 1-3, 12-14, 19-20, 30-32 and 40-41, the device for regulating and controlling urethral pressure includes a support assembly 1, a pressing assembly 2 and an adjusting assembly 3, the support assembly 1 is used for being mounted on a pubic bone 4, the pressing assembly 2 is mounted on the support assembly 1, the pressing assembly 2 is used for pressing a urethra 5, and the adjusting assembly 3 is used for controlling the pressure of the pressing assembly 2 on the urethra 5 by a user in vitro.

In this embodiment, the device for regulating urethra pressure is installed on pubis 4 of a user through a support component 1, a pressing component 2 is installed on the support component 1, the pressing component 2 can press urethra 5, the pressing component 2 is controlled by an adjusting component 3 as a movable component, the user can operate the adjusting component 3 in vitro, and adjust the pressure of the pressing component 2 pressing urethra 5, so that urethra 5 is in an open state (the pressure borne by urethra 5 is zero) as shown in fig. 4, urethra 5 is not pressed for a long time, thereby reducing the risk of necrosis of relevant cell tissues of urethra 5 due to blood circulation for a long time, or making urethra 5 in a closed state (urethra 5 bears maximum allowable pressure) as shown in fig. 5, and preventing urine leakage before the user needs normal urination, so as to avoid inconvenience for life of the user, or according to volume changes of relevant cell tissues of urethra 5 under different physiological states of different users, the urethra 5 is in a general compression state between the closed state and the open state, the pressure borne by the urethra 5 in the general compression state is greater than the pressure in the open state and smaller than the pressure in the closed state, different use requirements of a user are met, and therefore use experience of the user is improved. The device can meet different urine control requirements of moderate and severe urinary incontinence patients, and is not limited by gender. The doctor is easy to operate, and the probability that complications such as hematuresis and the like are easily caused by the suspension band or the artificial sphincter is reduced.

It should be noted that, compared with the suspension technique in the prior art, the problem that the tightness cannot be adjusted in vitro is solved. Compared with Artificial Urethral Sphincter (AUS) treatment, the principle of the artificial urethral sphincter is that the urethral pressure is controlled by connecting three parts of the oversleeve, the liquid storage bag and the control pump which are arranged in a human body and using hydraulic pressure difference to achieve the effect of controlling urine, but if a patient discharges urine, the oversleeve immediately restores the full state to continuously press the urethra, and the urethra is necrotized and atrophied over time. This application presses opening and shutting of subassembly 2 oppression urethra 5 through adjusting part 3 external control, lets the patient according to diet and urination law, and the user health is cared in the time that suitable reduction extruded urethra 5, prevents urethra 5 necrosis and atrophy, and has evaded the device complicacy and lead to the loaded down with trivial details shortcoming of operation, has reduced the probability of failure of postoperative device, has reduced the emergence frequency of some postoperative complications.

In addition, compare in prior art artificial sphincter of urethra (AUS) treatment mode, this application is different from and extrudees the urethra through the principle of regulation hydraulic pressure, extrudees the urethra through mechanical structure motion drive principle, and hydraulic drive needs to guarantee the gas tightness of whole equipment, so cause the trouble of device itself easily, compares, and the required condition of mechanical structure motion drive does not need the condition of device gas tightness. The structure of the application is formed by matching fewer components, and from the complexity of an implantation operation and an operation event, the reduction of the structural components also means that the matching of the device and a human body is reduced, the contact area with the human body is reduced, and the probability of postoperative complications caused by the fact that the device erodes the human body is weakened. More importantly, the device provided by the application enables a patient to control the opening and closing of the urethra 5 at any time through structural innovation according to own will, namely, the squeezing of the urethra 5 is controlled, when the patient does not feel urinary pressure or needs to control the opening and closing of the urethra 5 according to own eating habits and urination rules, the urethra 5 can be prevented from being excessively squeezed all the time to cause tissue atrophy, so that the urinary incontinence can recur.

The application provides a device of regulation and control urethra pressure through fixing supporting component 1 at pubis 4 or pubis combined lower margin 43 position, will press subassembly 2 to install at supporting component 1, controls the urination of urethra 5, makes the implantation operation simplify, weakens the fatigue strength of doctor's operation. Meanwhile, the pressing component 2 can be operated outside the body of the patient to regulate and control the discharge of urine, so that the patient can move more conveniently compared with normal people.

Wherein, the user can utilize wireless control mode, the internal electromagnetic structure of control or electronic structure, and then control and press subassembly 2 and oppress the pressure of urethra 5, or, the user directly adopts the higher manual mode of economic nature, separates the pressing subassembly 2 of skin control mechanical structure.

For the convenience of the reader, according to the classification of the control modes and the structures, the first embodiment and the second embodiment of the electromagnetic driving in the wireless control mode are firstly introduced, then the third embodiment and the fourth embodiment of the electric driving in the wireless control mode are introduced, then the fifth embodiment combining the wireless control mode and the manual mode is introduced, and finally the sixth embodiment of the manual mode is introduced.

In the wireless control mode, referring to fig. 3, 8-10, 18, and 24-35, the adjusting assembly 3 includes a driving member 31, a wireless controller 32, a battery (not shown) and a circuit board (not shown), the battery and the circuit board are mounted on the supporting assembly 1, the driving member 31 is mounted on the supporting assembly 1 and/or the pressing assembly 2, the battery and the circuit board are electrically connected to the driving member 31, and the wireless controller 32 is used for controlling the circuit board by a user in vitro, controlling the current magnitude and direction of the battery, and then controlling the driving member 31 to drive the pressing assembly 2 to move, so as to adjust the pressure of the pressing assembly 2 on the urethra 5.

In this embodiment, the user can utilize wireless controller 32 to send control command to internal circuit mainboard at external according to the rule of urinating and the physiological state of oneself to utilize the electric energy of battery to control the motion of driving piece 31, adjust at any time and press the pressure that subassembly 2 oppressed urethra 5, can satisfy user's user demand, can reduce urethra 5 again because of the risk of long-time oppression ischemia necrosis, and user's operation difficulty is not high.

In one embodiment, referring to fig. 4-8, 15-18, 21-24 and 27, the pressing assembly 2 includes a retractable member 21, and the driving member 31 controls the length of the retractable member 21.

For example, as the extendable element 21 shortens, the lumen space becomes smaller, and the pressure to which the urethra 5 is subjected becomes larger, and vice versa. The mode that changes scalable piece 21 length and adjust urethra 5 and bear pressure in this embodiment, its required home range is less, can simplify the structure of the device of regulation and control urethra pressure to adapt to the limited space of human inside size, have good human adaptability, improve user and use experience.
