Description

Technical Field

[0001] The present invention relates to a medical mechanical artificial organ, belonging to the technical field of medical devices, and mainly relates to an implantable remotely operated magnetically controlled intelligent sensing artificial bladder device applicable to patients in need of bladder replacement and its control method. Background Art

[0002] Organ replacement is to replace the organs that have lost their functions in patients to save their lives. Organ replacement mainly includes organ transplantation and artificial organs. Organ transplantation is limited by the source of organ donors and the immune rejection reaction after transplantation, while artificial organs have better advantages. Installing an artificially manufactured device with organ functions in the body has reliable mechanical stability, and artificial organs can be mass-produced and are easy to store. Currently, artificial organs mainly include three types: mechanical artificial organs, semi-mechanical semi-biological artificial organs, and biological artificial organs. The main artificial organs are still mostly mechanical artificial organs.

[0003] Bladder cancer has become the most common malignant tumor in the urogenital system. For the treatment of middle and late stage bladder cancer, the commonly used surgical methods clinically are ileal conduit, orthotopic neobladder, and ureterocutaneostomy. The ileal conduit intercepts a section of ileum as the output tract, which is the most widely used urinary diversion surgical procedure, but it requires abdominal wall stoma and wearing a urine collection bag for life. The orthotopic neobladder uses the terminal ileum to make a urine storage sac to replace the bladder, and situations such as nocturnal urinary incontinence and micturition failure will occur. Bacterial infections are prone to occur at the ureterocutaneous stoma, and an external urine collector is required, which brings serious troubles to the patient psychologically and in social life. Therefore, the problem of urinary diversion after total cystectomy in patients is still a major problem so far.

[0004] A large number of research scholars have tried to manufacture artificial bladders to replace the autologous bladder to solve the existing problems in clinical practice. The existing artificial bladders are mainly divided into two types: assisting urination on the basis of the human bladder to increase the contractility of the detrusor (such as CN11500994, CN105769379, etc.), and replacement artificial bladders (CN110856669, CN106580517, CN1339290, etc.). The assisted artificial bladder is only for patients with poor bladder function but still retaining the bladder. And the energy driving sources of the existing artificial bladders are basically rechargeable batteries, and there are inevitably some problems when implanted in the human body, such as the phenomenon of human tissue heating during wireless charging or the potential safety hazards of the implanted battery itself. In addition, there is also a method of urinating by applying external pressure (CN11519225), and knowing the urination time by observing the abdominal wall with the human eye. This method has a poor degree of intelligence, a high degree of discomfort for the human body, and a risk of over-accumulation of urine in the bladder. Currently, there is no relevant report or treatment in the existing artificial bladder patents that are actually applicable. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an implantable remotely operated magnetically controlled intelligent sensing artificial bladder device and its control method. The present invention is an artificial bladder intelligent control device designed according to the natural urine storage and urination functions of the bladder, adopting a brand-new mechanical structure, drive control method and intelligent feedback.

[0006] An implantable remotely operated magnetically controlled intelligent sensing artificial bladder device of the present invention includes a bladder main component, which includes a flexible prosthesis and an outer wrapping component. The flexible prosthesis is connected to an inlet one-way valve and an outlet one-way valve. The inlet one-way valve is anastomosed with the human ureter, and its opening pressure threshold is approximately 0, so that urine in the ureter can pass through the inlet one-way valve unobstructed and enter the flexible prosthesis for urine storage. The outlet one-way valve is anastomosed with the human urethra and has a preset opening pressure threshold.

[0007] The outer wrapping component includes a top cover and a bottom shell connected in a sealed manner. An internal multi-pole magnet, a horizontal pressing plate, and a flexible prosthesis in the inner cavity of the outer wrapping component are coaxially connected in series on a lead screw from top to bottom. The upper and lower ends of the lead screw are respectively connected to the bottom surfaces of the top cover and the bottom shell through bearings. The central hole of the internal multi-pole magnet is key-connected to the lead screw. A nut is installed in the central hole of the horizontal pressing plate. The lead screw meshes with the nut, and the lead screw passes through the central hole of the flexible prosthesis.

[0008] A vertical guide rail parallel to the lead screw is installed on the side wall of the bottom shell. A slider is connected to the circumferential edge of the horizontal pressing plate, and the slider is arranged on the vertical guide rail and slides along the vertical guide rail.

[0009] A urine pressure sensor is provided inside the flexible prosthesis, and the urine pressure sensor transmits data to a mobile terminal outside the body in a wireless transmission manner.

[0010] It further includes: an external driving device that provides an external magnetic field for driving the internal multi-pole magnet to rotate.

[0011] The internal multi-pole magnet is a disc body, and sector magnets with N and S poles are alternately distributed on the upper surface of the disc body; the external driving device includes an external multi-pole magnet having the same structure as the internal multi-pole magnet and a driving component for driving the external multi-pole magnet to rotate.

[0012] Preferably, there are 2 inlet one-way valves, and the two inlet one-way valves are respectively anastomosed with two human ureters.

[0013] Preferably, the preset opening pressure threshold of the outlet one-way valve is greater than the pressure of normal urine storage and less than the pressure generated when the flexible prosthesis is completely filled with urine.

[0014] Preferably, the flexible prosthesis has a corrugated structure and has excellent scalability; the inner surface of the flexible prosthesis has a coating to prevent urine adhesion and crystallization.

[0015] Preferably, the urine pressure sensor is a self-powered pressure sensor.

[0016] An implantable remotely operated magnetically controlled intelligent sensing artificial bladder device according to the present invention, the device comprising a bladder main body component, a magnetic force control system, an intelligent sensing system and an external wrapping structure;

[0017] Wherein:

[0018] The bladder main body component is composed of a bladder urine storage structure, two inlet one-way valves and one outlet one-way valve. The bladder urine storage structure includes a housing composed of a top cover and a bottom shell and an internal multi-pole magnet, a lead screw guide component and a flexible prosthesis located inside the housing; the flexible prosthesis has a urine storage function, and three pipes communicating with the inside of the flexible prosthesis are provided thereon, and the three pipes extend out of the housing and are respectively connected to one end of two inlet one-way valves and one outlet one-way valve outside the housing;

[0019] The magnetic force control system is composed of an internal multi-pole magnet and an external hand-held magnetic field. The internal multi-pole magnet is fixedly installed on the lead screw guide component, and the internal multi-pole magnet is driven to rotate by the external magnetic field, driving the lead screw guide component to apply pressure to the flexible prosthesis, so as to discharge the urine stored in the flexible prosthesis through the outlet one-way valve.

[0020] The intelligent sensing system mainly consists of a self-charging pressure sensor installed at the bottom of the flexible prosthesis and an external intelligent receiving device.

[0021] The external wrapping structure is composed of a polymer structure with good biocompatibility, mainly wrapping the internal mechanical structure.

[0022] The implantable remotely operated magnetically controlled intelligent sensing artificial bladder device according to the above technical solution. The two inlet one-way valves are respectively anastomosed with two ureters of the human body, and their opening pressure is approximately 0, and the urine in the ureters can pass through the inlet one-way valve unobstructed and enter the flexible prosthesis for urine storage. However, the urine in the flexible prosthesis cannot flow back into the ureters reversely through the inlet one-way valve. The inlet one-way valve can effectively prevent urine reflux and effectively protect renal function. The outlet one-way valve can only be opened when an external magnetic field applies pressure, and the normal urine storage pressure cannot open the outlet one-way valve, which can effectively prevent urine leakage. When the pressure generated when the flexible prosthesis is completely filled with urine can open the outlet one-way valve, thus preventing the flexible prosthesis from being overfilled

[0023] The magnetic force control system is composed of an internal multi-pole magnet and an external hand-held magnetic field. The external magnetic field drives the internal multi-pole magnet to rotate, driving the lead screw guide component to apply pressure to the flexible prosthesis, so as to discharge the urine stored in the flexible prosthesis through the outlet one-way valve.

[0024] The described intelligent sensing system is mainly installed at the bottom of the flexible prosthesis. The described intelligent feedback system detects the pressure inside the flexible prosthesis to feedback the urine storage and urination conditions of the artificial bladder device.

[0025] When the urine stored in the flexible prosthesis reaches a certain volume, the self-powered urine pressure sensor sends an alarm signal to the external mobile terminal; the pressure for sending the alarm signal is lower than the opening pressure of the outlet one-way valve.

[0026] The control method of the implantable remote operation magnetically controlled intelligent sensing artificial bladder device includes the following steps:

[0027] 1) Bladder urine storage: Urine flows into the flexible prosthesis through the inlet one-way valve. When the urine gradually increases, the flexible prosthesis expands along the axial direction of the lead screw;

[0028] 2) Driving urination: When the urine storage volume in the flexible prosthesis reaches the axial preset value, the pressure sensor in the flexible prosthesis sends a urination warning signal to the mobile terminal to remind the patient to urinate; based on the principle of like poles repelling and opposite poles attracting of magnets, the internal multi-pole magnet is driven to rotate forward by an external magnetic field, driving the lead screw fixedly connected to the internal multi-pole magnet to rotate forward. The horizontal pressing plate moves linearly downward along the lead screw through the nut, compressing the flexible prosthesis. At this time, the pressure at the outlet one-way valve gradually increases to its opening pressure, and the urine is discharged from the outlet one-way valve, and the flexible prosthesis gradually shrinks to its initial state;

[0029] If the patient does not receive the urination warning signal, as the urine gradually increases, the flexible prosthesis continues to expand along the axial direction of the lead screw until it contacts the horizontal pressing plate. The pressure inside the flexible prosthesis gradually increases, and the pressure at the outlet one-way valve gradually increases to its opening pressure, and the urine is discharged from the outlet one-way valve automatically, thus preventing the flexible prosthesis from over-expanding and bursting;

[0030] Restoring the pressing plate to the initial state: The internal multi-pole magnet is driven to rotate reversely by an external magnetic field, driving the lead screw fixedly connected to the internal multi-pole magnet to rotate reversely. The horizontal pressing plate moves linearly upward along the lead screw through the nut, moving away from the flexible prosthesis to reach the initial state, so as not to limit the expansion and urine storage function of the flexible prosthesis.

[0031] [[ID=2!]]The beneficial effects of the present invention are as follows:

[0032] The present invention achieves the purpose of remotely operating the in-vivo implanted bladder to urinate through a magnetic field, which can avoid the phenomenon of human tissue heating caused by wireless charging of the implantable battery, and improve the safety and comfort of implantable medical devices. At the same time, through the intelligent feedback of the urine volume change by the mobile terminal (such as the mobile phone APP), the patient is reminded to urinate in a timely manner, and the autonomous urination function is included, greatly improving the intelligent level of bladder urination. In addition, holding an external driving device to urinate has good portability. Description of the Drawings

The main bladder component 1 includes a flexible prosthesis 14 and an external wrapping component. The flexible prosthesis 14 is connected to an inlet check valve 2 and an outlet check valve 3. The inlet check valve 2 is respectively anastomosed with two ureters of the human body, and its opening pressure threshold is approximately 0. Urine in the ureters can pass through the inlet check valve 2 unobstructed and enter the flexible prosthesis 14 for urine storage.

[0041] The external wrapping component includes a top cover 11 and a bottom shell 15 that are hermetically connected. An internal multi-pole magnet 12, a horizontal pressure plate 135, and a flexible prosthesis 14 are coaxially connected in series on a lead screw 132 from top to bottom in the inner cavity of the external wrapping component. The upper and lower ends of the lead screw 132 are respectively connected to the bottom surfaces of the top cover 11 and the bottom shell 15 through bearings. The central hole of the internal multi-pole magnet 12 is key-connected to the lead screw 132. The central hole of the horizontal pressure plate 135 is provided with a nut 134. The lead screw 132 is engaged with the nut 134, and the lead screw 132 passes through the central hole of the flexible prosthesis 14;

[0042] A vertical guide rail 138 parallel to the lead screw 132 is installed on the side wall of the bottom shell 15.

[0043] A urine pressure sensor is provided inside the flexible prosthesis 14, and the urine pressure sensor sends data to a mobile device outside the body in a wireless transmission manner;

[0044] It further includes: an external driving device that provides an external magnetic field for driving the rotation of the internal multipole magnet 12.

[0045] The overall diagram of the implantable remotely operated magnetically controlled artificial bladder designed by the present invention is as Figure 1 shown, and mainly includes: a bladder main body component 1, an inlet check valve 2, and an outlet check valve 3. The bladder main body component 1 is respectively connected to one end of two inlet check valves 2 and one outlet check valve 3 through three extended pipes. The other ends of the two inlet check valves 2 are anastomosed with two ureters of the human body through surgery, and their opening pressure is approximately 0. Urine in the ureters can enter the bladder main body component 1 through the inlet check valve 2 without obstruction for urine storage. The other end of the outlet check valve 3 is anastomosed with the human urethra through surgery and has a certain opening pressure. When the urine is stored in the bladder main body component 1 to a certain volume, under the drive of the external driving device, the urine can be discharged from the outlet check valve 3.

[0046] The exploded view of the bladder main body component 1 is as Figure 2 shown, and includes: a top cover 11, an internal multipole magnet 12, a lead screw guide rail component 13, a flexible prosthesis 14, and a bottom shell 15. The meanings of the letters are: magnetic north pole N and magnetic south pole S. The top cover 11 and the bottom shell 15 are installed through an annular hole groove and fixed with a medical waterproof adhesive to form a rigid framework fixed inside the human abdominal cavity for supporting the operation of the internal moving components. Figure 2 The left figure shows the pole distribution on the upper surface of the internal multipole magnet 12. The magnet is axially magnetized, and the N and S poles are staggered. The number of poles is determined according to the distribution angle of the N / S poles (8 poles or more). Figure 2 The right figure shows the exploded view of the lead screw guide rail component 13, and includes: a bearing 131, a lead screw 132, a nut fixing bolt 133, a nut 134, a horizontal pressure plate 135, a slider fixing bolt 136, a slider 137, and a vertical guide rail 138.

[0047] The flexible prosthesis 14 is located within the bottom shell 15, has a corrugated pipe structure, and is provided with an inner hole at its center. The inside of the corrugated pipe has a urine storage function; the pressing plate 135 is located above the flexible prosthesis 14. The center of the pressing plate 135 is provided with a central hole and bolt holes surrounding the central hole. The nut 134 is installed at the central hole of the horizontal pressing plate 135 and fixed by the bolt 133 through the nut; the lead screw 132 passes through the inner hole of the nut 134 and the inner hole of the flexible prosthesis 14. Bearings 131 are installed at the upper and lower ends of the lead screw 132, and the bearings are fixed at the upper groove opened on the inner side of the top cover and the lower groove opened on the inner side of the bottom shell, so that the lead screw 132 can rotate around the central axis under the support of the bearings; the edge of the horizontal pressing plate 135 is installed on the vertical guide rail 138 through the slider 137 and fixed by the slider fixing bolt 136; the lead screw 132 is threadedly connected with the inner hole of the nut 134, and when the lead screw rotates, it drives the nut 134 to move up and down.

[0048] When the lead screw rotates, due to the restrictive effect of the circumferential degree of freedom of the vertical guide rail 138, the horizontal pressing plate 135 can move up and down along the axial direction of the lead screw 132 under the drive of the nut 134. In this embodiment, the material of the flexible prosthesis 14 is made of medical silicone, has a corrugated pipe structure, and has certain axial expansion and compression characteristics. Three pipes are provided at the bottom of the flexible prosthesis 14, and the three pipes respectively cooperate with three circular holes in the bottom shell 15 and then extend to the outside of the bladder main body component 1 and are connected to the inlet check valve 2 and the outlet check valve 3.

[0049] Figure 3 It is a cross-sectional view of the magnetically controlled artificial bladder. The inner holes of the bearings 131, the lead screw 132, the inner hole of the flexible prosthesis 14, the central hole of the pressing plate, the inner hole of the nut 134, and the internal multi-pole magnet 12 are coincident in axis during installation. The two bearings 131 are respectively installed in the grooves of the bottom shell 15 and the top cover 11 along the axial direction. The lead screw 132 and the nut 134 are connected by axial threads or have internal balls. The internal multi-pole magnet 12 is fixedly installed at a position close to the upper end of the lead screw through its inner hole, and the rotation of the internal multi-pole magnet 12 can directly drive the lead screw to rotate. The two bearings 131 are installed at both ends of the lead screw 132 to reduce the friction force when the lead screw 132 rotates relative to the top cover 11 and the bottom shell 15. The upper and lower ends of the vertical guide rail are respectively embedded in the vertical grooves of the bottom shell 15 and the top cover 11 for fixation.

[0050] Figure 4Overall schematic diagram of a handheld external drive device, including: an external multipole magnet 4 and a drive assembly 5. The external multipole magnet 4 has the same structure as the internal multipole magnet 12, is axially magnetized, and the N and S poles are staggered. In this embodiment, the drive assembly 5 includes a protective housing, a drive motor, a drive circuit board, a battery, etc. The handheld external drive device can receive the urination signal from the self-powered pressure sensor inside the bladder, press it against the muscle layer at the human bladder, drive the external multipole magnet 4 to rotate, and thus realize the intelligent urination function. In this embodiment, the alarm pressure of the self-powered pressure sensor is less than the opening pressure of the outlet check valve 3.

[0051] For the external multipole magnet and the internal multipole magnet, in addition to the form shown in the figure, there are other options. For example, the magnetization direction array can be changed to a circular axial Halbach array, so as to enhance the magnetic force between the two magnets and increase the pressure of the pressing plate 135.

[0052] The working principle of this artificial bladder is as Figure 5 shown. Character definitions: urine u, human muscle layer L at the bladder. The working process is divided into the following three steps:

[0053] (1) Bladder urine storage: As Figure 5 (a), the pressing plate approaches the upper end of the lead screw. Urine u flows from the ureter through the inlet check valve 2 (opening pressure approximately 0) into the flexible prosthesis 14. When the urine gradually increases, the outlet check valve 3 has a certain opening pressure, and the urine will not flow out from the outlet check valve. Since the flexible prosthesis 14 is a corrugated pipe structure, the flexible prosthesis 14 will expand axially along the lead screw 132;

[0054] (2) Driving urination: As Figure 5(b) When the urine storage capacity of the prosthesis 14 reaches a preset axial value (e.g., 80% of the maximum axial value), the pressure sensor in the prosthesis sends an alarm signal, and the mobile terminal receives the signal to remind the patient to urinate. The patient holds the external drive device and presses it against the muscle layer L of the human bladder to drive the external magnet 4 to rotate. Due to the principle of magnets with like poles repelling and unlike poles attracting, the internal multipolar magnet 12 implanted in the artificial bladder in the human body rotates in approximately synchronous and synchronizing directions, driving the screw 132 connected to the internal multipolar magnet 12 to rotate. Due to the fixing effect of the vertical guide rail 138 in the circumferential degree of freedom, the pressure plate 135 moves linearly downward along the screw 132 through the nut 134, compressing the flexible prosthesis 14. At this time, the pressure at the outlet one-way valve gradually increases and reaches its opening pressure. Urine u is discharged from the outlet one-way valve 3, and the volume of the flexible prosthesis gradually shrinks to its initial state. If the patient does not receive the urination warning signal for some reason, as the urine gradually increases, the flexible prosthesis 14 will continue to expand along the axial direction of the screw 132 until it contacts the upper end pressure plate, and the pressure inside the flexible prosthesis will gradually increase. The pressure at the outlet one-way valve 3 will gradually increase and reach its opening pressure. The urine u will also be discharged from the outlet one-way valve 3 on its own, thereby preventing the flexible prosthesis from over-expansion and bursting;

[0055] (3) The pressure plate is restored to its initial state: Figure 5 (c) The pressure plate is now near the lower end of the lead screw. The patient holds an external drive device to drive the external magnet 4 in reverse rotation, causing the internal multipolar magnet 12 in the artificial bladder to rotate in a nearly synchronous counter-rotational manner. Similarly, the pressure plate 135 is moved linearly upward along the lead screw 132 via the nut 134, reaching its initial state, thereby unrestricting the expansion and urine storage function of the flexible prosthesis 14.

[0056] The above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and many variations are possible. All variations that can be directly derived or imagined by a person skilled in the art from the disclosure of the present invention should be considered to be within the scope of protection of the present invention.
