Description

Technical Field

[0001] The present invention relates to the technical field of urinary control, and in particular to an implantable bionic urinary control system. Background Art

[0002] The urinary system consists of the kidneys, ureters, bladder, and urethra, and its primary function is excretion. Excretion refers to the physiological process by which various unused or harmful substances produced during the body's metabolism are transported out of the body. Urine produced by the kidneys flows through the ureters into the bladder for temporary storage. When the urine volume reaches a certain level, it is excreted from the body through the urethra. Therefore, the urinary system can be said to be the collective term for the organs that produce, transport, store, and excrete urine. The bladder's urination reflex is controlled by the urination center in the cerebral cortex and spinal cord, and the pudendal nerve transmits this information to the somatic nerves, allowing urination to be controlled consciously. These control nerves are collectively referred to as peripheral nerves.

[0003] The peripheral nerves mainly include afferent nerves and efferent nerves. The afferent nerves transmit the neural electrical signals to the sensor, which is the bladder wall. After the sensor receives the neural electrical signal input, it inputs the neural electrical signal into the efferent nerves. The efferent nerves input the neural electrical signal into the effector, which is the bladder urinary control muscle group. After the bladder urinary control muscle group receives the neural electrical signal, the bladder urinary control muscle group contracts to discharge the urine stored in the bladder.

[0004] Peripheral nerve damage can easily lead to urinary muscle disorders, urinary incontinence, and urinary dysfunction. Patients with these symptoms are often unable to urinate normally, and their urinary control ability and quality of life are poor. However, there is currently no effective solution to the problem of peripheral nerve damage.

[0005] Therefore, an implantable bionic urinary control system is needed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0041] like Figure 1 As shown, the embodiment of the present invention discloses an implantable bionic urinary control system, including neuroelectrophysiological detection: by performing neuroelectrophysiological detection on peripheral nerves, damaged units are detected;

[0042] Electrical signal monitoring module: The electrical signal monitoring module is connected to the upstream of the damaged nerve unit to monitor the input of nerve signals;

[0043] Electrical signal output module: the electrical signal output module is connected to the injury electrical signal monitoring module, and the electrical signal output module is connected to the downstream of the injured nerve unit;

[0044] Central controller 1: The central controller 1 includes a power supply unit 12 and a control unit 11 , and the electrical signal output module and the electrical signal monitoring module are connected to the control unit 11 .

[0045] Specifically, the patient's nerve tissue is tested clinically, and the damaged points of the nerve tissue are detected using electrophysiological instruments such as patch clamps and micromotors to locate the specific damaged parts of the patient's urinary peripheral nerves. After that, the electrical signal monitoring module and the electrical signal output module are installed.

[0046] When a patient's afferent nerves are damaged but the efferent nerves are normal, the electrical signal monitoring module is connected to the upstream of the damaged afferent nerve site, and the electrical signal output module is connected to the downstream of the damaged afferent nerve site to achieve a bypass. When the urination signal is transmitted, the urination electrical signal first enters the electrical signal monitoring module, and the electrical signal monitoring module sends a signal to the central processing unit 1. After receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module transmits the signal to the downstream of the damaged afferent nerve, thereby controlling the patient's normal urination.

[0047] When the patient's efferent nerves are damaged but the afferent nerves are normal, the electrical signal monitoring module is connected to the upstream of the efferent nerve damage, and the electrical signal output module is connected to the downstream of the efferent nerve damage site to achieve a bypass; when the urination signal is transmitted, the urination electrical signal is transmitted through the afferent nerves, and then transmitted to the sensor, and then the electrical signal is transmitted to the efferent nerves, and then detected by the electrical signal monitoring module, the electrical signal monitoring module sends a signal to the central processing unit 1, after receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module transmits the signal to the downstream of the efferent nerve damage site, thereby enabling the patient to urinate normally.

[0048] When both the afferent nerves and the efferent nerves are damaged, the electrical signal monitoring module is connected to the upstream of the damaged site of the afferent nerves, and the electrical signal output module is connected to the downstream of the damaged site of the efferent nerves to achieve bridging; when the urination signal is transmitted, the urination signal first enters the electrical signal monitoring module, and then the electrical signal monitoring module sends a signal to the central processing unit 1. After receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module transmits the signal to the downstream of the damaged site of the efferent nerves, thereby enabling the patient to urinate normally.

[0049] Furthermore, neuroelectrophysiological testing is an existing technology and will not be described in detail.

[0050] By setting up the electrical signal monitoring module and the electrical signal output module, the damaged parts of the afferent nerves or efferent nerves can be reconnected to ensure that the peripheral nerve circuit is unobstructed and that the patient can urinate normally.

[0051] Further, such as Figure 2 As shown, the urine volume monitoring module: the urine volume monitoring module includes a bladder tension sensor, which is attached to the bladder wall and connected to the control unit 11. The bladder tension sensor is a flexible sensor, and a threshold is set for the bladder tension sensor. If the muscle tension exceeds the threshold, the electrical signal is transmitted downstream.

[0052] Furthermore, a corresponding threshold is set for the bladder tension sensor according to the patient's bladder size.

[0053] Specifically, when the patient undergoes neuroelectrophysiological testing and detects that the sensor, that is, the bladder wall, is damaged, the bladder tension sensor is attached to the bladder wall, and then the bladder tension sensor is connected to the electrical signal monitoring module, the electrical signal monitoring module is connected to the central controller 1, the central controller 1 is connected to the electrical signal output module, and the electrical signal output module is connected to the downstream of the sensor, that is, the efferent nerve; when the bladder tension sensor senses that the muscle tension of the bladder wall exceeds the threshold, it sends an electrical signal to the electrical signal monitoring module, the electrical signal is transmitted to the central controller 1, and after processing by the central controller 1, the central controller 1 sends a signal to the electrical signal output module, and the electrical signal output module sends a signal to the efferent nerve, thereby controlling the patient's normal urination.

[0054] Through the setting of the urine volume monitoring module, when the sensor of the afferent nerve is damaged and cannot work normally, the bladder tension sensor can sense the urine volume in the bladder. When the threshold is reached, the central controller 1 and the electrical signal output module are used to control the patient's normal urination.

[0055] Further, such as Figure 3 As shown, the electromyographic signal output module: the electromyographic signal output module is connected to the bladder urinary control muscle groups respectively, and the electromyographic signal output module includes a bladder sphincter stimulation unit and a bladder detrusor stimulation unit, the bladder sphincter stimulation unit is connected to the bladder sphincter, the bladder detrusor stimulation unit is connected to the bladder detrusor, and the electromyographic signal output module is connected to the control unit 11.

[0056] Specifically, when the patient undergoes neuroelectrophysiological testing and the effector, i.e., the bladder urinary control muscle group, is detected to be damaged, the electrical signal monitoring module is connected to the upstream of the bladder urinary control muscle group, the electrical signal output module is connected to the electromyographic signal output module, and the electromyographic signal output module is connected to the bladder urinary control muscle group; when the electrical signal monitoring module detects the electrical signal input, the electrical signal monitoring module sends a signal to the central processing unit 1, the central processing unit 1 sends a signal to the electrical signal output module, the electrical signal output module sends a start signal to the electromyographic signal output module, and at the same time, the central processing unit 1 transmits power to the electromyographic signal output module through the control unit 11, so that the electromyographic signal output module sends a signal to the bladder urinary control muscle group, thereby controlling the patient's normal urination.

[0057] Through the setting of the electromyographic signal output module, when the bladder urinary control muscle group is damaged and cannot work normally, the electromyographic signal output module can send a signal to the bladder urinary control muscle group, so that the patient can urinate normally.

[0058] Further, such as Figure 6 As shown, the power supply unit 12 includes a wireless charger 121 and a lithium battery 122 , the wireless charger 121 is connected to the lithium battery 122 , and the central controller 1 is buried under the abdomen.

[0059] It should be noted that the control unit 11 and the wireless charger 121 are prior art and will not be described in detail.

[0060] Specifically, the power supply unit 12 provides power to the control unit 11 to ensure the operation of the control unit 11. When the lithium battery 122 in the power supply unit 12 is low on power, the lithium battery is charged through the wireless charger 121. That is, the output end of the wireless charger 121 is placed on the patient's abdomen, and power is transmitted to the wireless charger 121 through wireless transmission. The wireless charger 121 stores the received power in the lithium battery 122.

[0061] Through the setting of the wireless charger 121, power can be transmitted to the central controller 1 by wireless transmission, ensuring long-term use of the central controller 1. At the same time, the central controller 1 is buried in the patient's abdomen, making it convenient for the patient to charge the central controller 1.

[0062] Further, such as Figure 7 As shown, the central controller 1 includes a shell 13, a mounting cavity 14 with an opening facing downward is provided in the shell 13, a closing cover 15 is provided at the open end of the mounting cavity 14, the closing cover 15 is in contact with the shell 13, a rubber pad is provided between the shell 13 and the closing cover 15, and the shell 13 and the closing cover 15 are connected by screws.

[0063] Further, if Figure 8 As shown, the closing cover 15 is connected to the housing 13 by eight screws evenly arranged along the circumferential direction.

[0064] Specifically, the control unit 11 and the power supply unit 12 are installed in the housing 13 , and then the closing cover 15 and the rubber pad are installed on the housing 13 by screws.

[0065] By providing the rubber pad, the sealing of the connection between the shell 13 and the closing cover 15 is ensured, thereby preventing a large amount of liquid from the human body from entering the shell 13, causing damage to the control unit 11 and the power supply unit 12 therein and affecting the service life of the device.

[0066] Further, such as Figure 6 As shown, the control unit 11 is fixedly connected to the closing cover 15, the lithium battery 122 is fixedly connected to the side of the control unit 11 away from the closing cover 15, the wireless charger 121 is fixedly connected to the side of the lithium battery 122 away from the control unit 11, the wireless charger 121 abuts against a side wall of the mounting cavity 14 away from the closing cover 15, and the wireless charger 121 is located on the side of the central controller 1 close to the abdominal outer skin tissue.

[0067] Specifically, during installation, one side of the wireless charger 121 is installed close to the patient's abdominal skin tissue.

[0068] By installing the wireless charger 121 close to the side of the abdominal epidermis, the wireless charger 121 can fit more closely with the external input device when working, facilitating the transmission of power. At the same time, the closing cover 15 is installed on the side away from the abdominal epidermis, making it convenient for the later operator to open the patient's abdominal epidermis and maintain the central controller 1.

[0069] Further, such as Figure 7 As shown, an annular partition plate 16 is provided on the closing cover 15 , and the partition plate 16 abuts against a side wall of the installation cavity 14 away from the closing cover 15 .

[0070] By providing the partition plate 16, the sealing between the closing cover 15 and the outer shell 13 is further improved, so that if the liquid in the patient's body enters the outer shell 13 through the gap between the closing cover 15 and the outer shell 13, the partition plate 16 can prevent the liquid from entering the outer shell 13, thereby further improving the safety of the device.

[0071] Further, such as Figure 7 As shown, an insertion hole 17 is provided on the shell 13, and the insertion hole 17 passes through the partition plate 16. The control unit 11 is provided with an interface 111. The electrical signal monitoring module, the electrical signal output module, the urine volume monitoring module, and the electromyographic signal output module are respectively connected to the interface 111 through a wire 18, and the wire 18 passes through the insertion hole 17. A closing member 19 is provided on the shell 13, and the closing member 19 includes a fixing ring 191 fixedly connected to the shell 13, and also includes a rubber ring 192 fixedly connected to the inner ring surface of the fixing ring 191, and the fixing ring 191 and the rubber ring 192 are coaxial with the insertion hole 17.

[0072] Furthermore, the number of insertion holes 17 , closing members 19 , and connectors 111 is determined according to the modules to be connected.

[0073] Specifically, when the system is installed in the patient's body, each module is first connected to the corresponding position, then the central controller 1 is installed, and then each module is connected to the central controller 1 through the wire 18, that is, the wire 18 is inserted into the shell 13 through the insert 19, and the wire 18 is connected to the interface 111, and at the same time the rubber ring 192 closes the gap between the wire 18 and the insertion hole 17.

[0074] The connection between the wire 18 and the interface 111 facilitates the connection between each module and the central processing unit 1, so that when the system is installed, the wire can avoid the tissue in the human body and connect to the central processing unit 1 according to the different installation positions of different modules. After avoiding the tissue in the human body, the wire is connected to the interface 111, which facilitates the installation of the system.

[0075] Further, such as Figure 7 As shown, the connector 111 is connected to the wire 18 by point contact, the partition plate 16 is rotatably arranged on the closing cover 15, and the partition plate 16 is connected to a driving member 10, and the driving member 10 can drive the partition plate 16 to rotate along the axis of the partition plate 16.

[0076] Furthermore, the driving member 10 includes an electromagnetic slide rail 101 fixedly connected to a side wall of the installation cavity 14 away from the closing cover 15. The electromagnetic slide rail 101 is annular. Two electromagnetic sliders 102 are slidably connected in the electromagnetic slide rail 101. An L-shaped rod 103 is fixedly connected to the lower side of each electromagnetic slider 102. The two electromagnetic sliders 102 are symmetrically arranged in the electromagnetic slide rail 101. The two electromagnetic sliders 102 move synchronously. The L-shaped rod 103 is fixedly connected to the partition plate 16. An annular slide groove with an opening toward the installation cavity 14 is opened in the closing cover 15. An annular slide is fixedly connected to the end of the partition plate 16 close to the closing cover 15. The annular slide is slidably connected in the annular slide groove, and a rubber strip is provided in the gap between the annular slide groove and the annular slide groove.

[0077] It should be noted that the electromagnetic slider 102 and the electromagnetic slide rail 101 are prior art and will not be described in detail.

[0078] Specifically, when the control unit 11 is damaged, in order to prevent the central controller 1 from sending erroneous signals to each module, the electromagnetic slider 102 is started, so that the electromagnetic slider 102 slides a certain distance in the electromagnetic slide rail 101. The electromagnetic slider 102 drives the partition plate 16 to rotate a certain angle through the L-shaped rod 103. The partition plate 16 drives the end of the wire 18 to move a certain distance, so that the wire 18 is disconnected from the connector 111, and the transmission of the electrical signal is stopped.

[0079] By setting the partition plate 16 and the driving member 10, when the control unit 11 is damaged, in order to prevent the central controller 1 from sending an erroneous signal to each module, the partition plate 16 is rotated to disconnect the wire 18 from the connector 111, thereby stopping the transmission of the electrical signal.

[0080] The electrical signal monitoring module includes a flexible electrical signal sensor, which is wrapped around the outside of the nerve fiber.

[0081] Working principle: Clinically, the patient's nerve tissue is tested, and the bad points of the nerve tissue are detected through electrophysiological instruments such as patch clamps and micromotors to locate the specific damaged parts of the patient's urinary peripheral nerves, and then the electrical signal monitoring module and the electrical signal output module are installed; when the afferent nerve is damaged but the efferent nerve is normal, the electrical signal monitoring module is connected to the upstream of the afferent nerve damage site, and the electrical signal output module is connected to the downstream of the afferent nerve damage site to achieve a bypass; when the urination signal is transmitted, the urination electrical signal first enters the electrical signal monitoring module, and the electrical signal monitoring module sends a signal to the central processing unit 1. After receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module is connected to the downstream of the afferent nerve damage site. The output module transmits the signal to the downstream of the afferent nerve damage, thereby controlling the patient's normal urination; when the efferent nerve is damaged but the afferent nerve is normal, the electrical signal monitoring module is connected to the upstream of the efferent nerve damage, and the electrical signal output module is connected to the downstream of the efferent nerve damage site to achieve a bypass; when the urination signal is transmitted, the urination electrical signal is transmitted through the afferent nerve, and then transmitted to the sensor, and then the electrical signal is transmitted to the efferent nerve, and then detected by the electrical signal monitoring module, the electrical signal monitoring module sends a signal to the central processing unit 1, after receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module transmits the signal to the downstream of the efferent nerve damage site, thereby achieving normal urination for the patient. When both the afferent nerves and the efferent nerves are damaged, the electrical signal monitoring module is connected to the upstream of the damaged site of the afferent nerves, and the electrical signal output module is connected to the downstream of the damaged site of the efferent nerves to achieve bridging; when the urination signal is transmitted, the urination signal first enters the electrical signal monitoring module, and then the electrical signal monitoring module sends a signal to the central processing unit 1. After receiving the signal, the central processing unit 1 sends a signal to the electrical signal output module, and the electrical signal output module transmits the signal to the downstream of the damaged site of the efferent nerves, thereby enabling the patient to urinate normally.

[0082] When the patient passes the neuroelectrophysiological test and the sensor, that is, the bladder wall is detected to be damaged, the bladder tension sensor is attached to the bladder wall, and then the bladder tension sensor is connected to the electrical signal monitoring module, the electrical signal monitoring module is connected to the central controller 1, the central controller 1 is connected to the electrical signal output module, and the electrical signal output module is connected to the downstream of the sensor, that is, the efferent nerve; when the bladder tension sensor senses that the muscle tension of the bladder wall exceeds the threshold, it sends an electrical signal to the electrical signal monitoring module, the electrical signal is transmitted to the central controller 1, and after being processed by the central controller 1, the central controller 1 sends a signal to the electrical signal output module, and the electrical signal output module sends a signal to the efferent nerve, thereby controlling the patient's normal urination. When the patient undergoes neuroelectrophysiological testing and the effector, i.e., the bladder and urinary control muscle group, is damaged, the electrical signal monitoring module is connected to the upstream of the bladder and urinary control muscle group, the electrical signal output module is connected to the myoelectric signal output module, and the myoelectric signal output module is connected to the bladder and urinary control muscle group; when the electrical signal monitoring module detects an electrical signal input, the electrical signal monitoring module sends a signal to the central processing unit 1, the central processing unit 1 sends a signal to the electrical signal output module, the electrical signal output module sends a start signal to the myoelectric signal output module, and the central processing unit 1 transmits power to the myoelectric signal output module through the control unit 11, so that the myoelectric signal output module sends a signal to the bladder and urinary control muscle group, thereby controlling the patient's normal urination. The power supply unit 12 provides power to the control unit 11 to ensure the operation of the control unit 11. When the lithium battery 122 in the power supply unit 12 is low on power, the lithium battery is charged by the wireless charger 121. That is, the output end of the wireless charger 121 is placed on the patient's abdomen and power is transmitted to the wireless charger 121 by wireless transmission. The wireless charger 121 stores the received power in the lithium battery 122. When installing the system in a patient's body, each module is first connected to its corresponding position, and then the central controller 1 is installed. Each module is then connected to the central controller 1 via wires 18. Specifically, wires 18 are inserted into the housing 13 through inserts 19 and connected to the interface 111. At the same time, rubber rings 192 seal the gap between wires 18 and insertion holes 17. If the control unit 11 is damaged, to prevent the central controller 1 from sending erroneous signals to the modules, the electromagnetic slider 102 is activated, causing it to slide a certain distance within the electromagnetic slide rail 101. The electromagnetic slider 102, via the L-shaped rod 103, drives the partition plate 16 to rotate a certain angle. The partition plate 16 then drives the end of the wire 18 to move a certain distance, disconnecting the wire 18 from the interface 111 and stopping the transmission of electrical signals.
