Description
Technical Field
The utility model relates to an external energy controller of a nerve stimulation system, which forms the nerve stimulation system together with an implanted nerve stimulator with a main control chip through radio frequency communication.
Background
Neurostimulation systems incorporating implantable neurostimulators have become widely used in the medical field. In such systems, an implantable neurostimulator is implanted within a patient to effect treatment of the affected site.
Conventional implantable neurostimulators require their own battery to supply power. When the battery is depleted, the neurostimulator implanted in the patient needs to be removed in order to reinstall the battery. In addition, when the physician needs to change the treatment plan, it is also necessary to remove the neurostimulator implanted in the patient in order to reconfigure the treatment plan. The treatment regimen includes, for example, the pulse width, frequency, etc. of the stimulation pulses. This is clearly painful for patients with long treatment periods.
To address this pain, neurostimulation systems based on radio frequency control have emerged. Chinese utility model patents CN104080509B and CN107789730B disclose such a neurostimulator system. The external energy controller provides electrical stimulation pulses in real time to drive a stimulation electrode of the implantable nerve stimulator so as to apply stimulation signals to a treatment part of a patient; and the external energy controller provides radio frequency electric energy to the implanted nerve stimulator to maintain the operation of the implanted nerve stimulator.
Compared with the traditional implantable neurostimulation system, the radio frequency-based neurostimulator can obtain unlimited power supply, so that the problem of battery depletion is not needed to be worried about. Moreover, the radio frequency-based implantable neural stimulator can adjust the electrical stimulation pulse at any time by the external energy controller according to the treatment scheme. There is no concern about repeated implantation problems due to battery depletion and changing treatment regimens.
However, there are many drawbacks to such prior art radio frequency based neurostimulation systems:
since the external energy controller needs to provide the electrical energy and the input signal (such as various stimulation pulse sequences) to the implantable neurostimulator at the same time, and needs to monitor the working state of the implantable neurostimulator in real time, it may not be able to implement the real-time operation of the implantable neurostimulator, which also has an adverse effect on the treatment process. To solve this problem, CN107789730B adopts a dual-frequency operation mode, which increases the complexity and manufacturing cost of the product and may result in an increase in the volume of the implantable neurostimulator. This increase in volume is clearly detrimental to the implantation of the neurostimulator.
In addition, since the electrical stimulation pulses of the implantable neurostimulator are provided by the external energy controller in real time, reliable communication between the neurostimulator implanted in the patient and the external energy controller must be ensured. The reliability of such communications can be affected by a number of factors. For example, when the external energy controller is away from the patient due to some factor, or when the external energy controller is accidentally impacted or damaged, even for a very long time, the treatment process of the implantable neural stimulator may be adversely affected.
The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Therefore, the problems of treatment safety and product complexity caused by the need of real-time communication of the implanted nerve stimulator system in the prior art are solved.

Fig. 3 shows a functional block diagram of an in vitro energy controller of the neurostimulation system of the present invention.
As shown in fig. 1 and 2, the external energy controller 2 of the neurostimulation system of the present invention transmits electric energy to the implantable neurostimulator 1 by radio frequency and communicates with the implantable neurostimulator 1. As shown in fig. 3, the in vitro energy controller 2 of the neurostimulation system of the present invention comprises: an input device 20, the external energy controller 2 receives information through the input device 20; the antenna module 21 is in radio frequency coupling with a stimulator antenna of the implantable neural stimulator 1, so that an input signal containing electric energy and control information is sent to the implantable neural stimulator 1, and instructions and data can be received from the implantable neural stimulator 1; a display device 22, wherein the display device 22 displays the current state of the external energy controller 2 and the information input from the input device 20, and also displays the data and instructions received from the implantable neural stimulator 1; a storage unit 23 which stores an operation program of the external power controller 2, information input from the input device 20, and data received from the implantable neurostimulator 1; a power supply 24 for supplying power to the external energy controller of the whole nerve stimulation system; and a control unit 25 controlling the connection of the input device 20, the antenna module 21, the power supply 24, and the display device 22, respectively, thereby controlling the operation of the entire external energy controller 2.
The user may operate the input device. The information input from input device 20 may include information to configure external controller 2, information to configure implantable neurostimulator 1, and instructions to read data into implantable neurostimulator 1. In addition, by operating input device 20, any information of in vitro controller 2 itself may also be displayed, including information stored in memory unit 23 (e.g., operational data from implantable neurostimulator 1).
The input device 20 may be any device suitable for inputting information, such as a key, a hand-written screen, a voice input microphone, etc. Preferably, the input device 20 has a stimulation intensity adjustment unit, which can adjust the stimulation intensity of the implantable neurostimulator 1 in an up-down manner. The stimulation intensity adjusting unit can be an up-down shifting key or a screen display virtual key.
The display device 22 may be any device capable of displaying information, such as a liquid crystal display, an LED display, or the like.
The storage unit 23 is preferably a nonvolatile memory so as to store data even after power is turned off. In this way, the external energy controller 2 of the neurostimulation system only needs to be configured for each patient according to the treatment scheme before each treatment phase begins, and the method can be applied to the whole treatment phase. Thus, the need for frequent set-up of the external energy controller 2 of the neurostimulation system by a physician is avoided.
The power source 24 may be a conventional battery or a rechargeable battery.
The instruction received from the implantable neurostimulator 1 is an instruction for adjusting the transmitting power of the external energy controller, and the control unit 25 adjusts the transmitting power of the antenna module 21 according to the instruction so as to meet the operation requirement of the implantable neurostimulator 1. This way of adjusting the transmit power according to the operational requirements of the implantable neurostimulator 1 is clearly more helpful to ensure reliable operation of the implantable neurostimulator 1.
The external energy controller 2 of the nerve stimulation system can also be provided with an upper computer communication module 26 for receiving instructions from the upper computer 3 and sending data to the upper computer 3, wherein the instructions configure the external energy controller 2 for the incoming nerve stimulation system or configure the implantable nerve stimulator 2; or used for transmitting various data of the external energy controller 2 of the nerve stimulation system and data from the implanted nerve stimulator 1 to the upper computer 3.
The upper computer 3 can be provided with special upper computer software, and a user can send an instruction to the external energy controller 2 of the nerve stimulation system through the upper computer software so as to operate the external energy controller 2 of the nerve stimulation system, or operate the implantable nerve stimulator 1 through the external energy controller 2 of the nerve stimulation system, wherein the operation comprises setting, measuring, programming and data management of clinical stimulation parameters.
The upper computer software can also operate the upper computer 3 to connect with a network or an internal server to perform backup and update of programs and data.
Obviously, the upper computer 3 and the included upper computer software can improve the convenience of operation and help to set more complicated treatment schemes.
The upper computer communication module 26 of the external energy controller 2 of the nerve stimulation system of the present invention may be a wireless communication module so as to exchange commands and data with the upper computer 3 in a wireless communication manner. Obviously, unlimited communication mode can make the external energy controller 2 of nerve stimulation system be connected more conveniently with being connected between the host computer 3 to improve the convenience of operation and the succinct nature of product design.
The wireless communication module can be a Bluetooth module.
The external energy control device 2 of the neurostimulation system of the utility model is often designed to be worn on one's person so as to be able to move anywhere with the patient. This wearable design requires the size of the product to be minimized, and therefore the battery size is also minimized, which requires a significant consideration for the energy-saving design of the device. The Bluetooth communication has the characteristic of low power consumption, and can well meet the energy-saving requirement.
The implantable neurostimulator 1 is required to have high safety as an in vivo therapeutic device. That is, an illegal operator or an illegal external control device is to be prevented from interfering with the implantable neurostimulator 1. Bluetooth also provides two-layer password protection, can prevent this illegal invasion risk more effectively.
Optionally, the wireless communication module may also be a WIFI module. Depending on the treatment regimen, certain treatment regimens may yield a large amount of data. This increases the amount of data that needs to be transmitted. The WIFI communication has high transmission speed, and the requirement is favorably met.
The external energy controller 2 of the nerve stimulation system of the utility model only needs to provide radio frequency electric energy without sending a real-time stimulation signal containing a stimulation electric pulse to the implanted nerve stimulator 1, so that treatment failure can not be caused even if communication is interrupted or is not smooth due to an emergency.
Because the implanted nerve stimulator 1 can send the data to the external energy controller in the intermittent treatment period or in the non-busy communication period, the external energy controller 2 of the nerve stimulation system can further ensure the smooth communication when the communication is needed, thereby improving the performance of the equipment. For example, when a doctor or a patient operates the in-vitro energy controller to send a command to the implanted neural stimulator, the implanted neural stimulator does not send data to the outside to ensure smooth communication.
The external energy controller 2 of the neurostimulation system of the utility model can ensure that the implanted neurostimulator 1 can obtain stable power supply because the external energy controller receives the instruction for adjusting the transmitting power from the implanted neurostimulator and responds the instruction to adjust the transmitting power of the antenna module.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the utility model to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the utility model and its practical application to enable others skilled in the art to make and use various exemplary embodiments of the utility model and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the utility model be defined by the following claims and their equivalents.
