[0007] The first control section includes a first control unit, and the first control unit includes a first control coil;

[0008] The stimulation part is configured to be implanted in the stimulation site of the test object, and the first control part is configured to be placed outside the test object. The first control part uses the coupling between the first control coil and the first coil to output energy to the first control module, and controls the stimulation degree of the first stimulation electrode through the first control module.

[0009] In some embodiments, the first control module includes a first stimulation module connected to the first coil; wherein the first coil is configured to be coupled to the first control unit to receive energy, and the first stimulation module controls the stimulation level of the first stimulation electrode according to the energy received by the first coil.

[0010] In some embodiments, the first control module further includes:

[0011] A rectifier module is used to rectify the energy received by the first coil to at least power the first stimulation module.

[0012] In some embodiments, the first control module further includes:

[0013] The signal acquisition module is used to acquire stimulation signals from the site to be stimulated.

[0014] In some embodiments, the first control unit includes a first control module connected to the first control coil, the first control module being used to control the energy output of the first control coil.

[0015] In some embodiments, the first control unit further includes a second control unit connected to the first control unit. The second control unit is used to set the energy output of the first control module. The first control module controls the energy output of the first control coil coupled to the stimulation unit according to the output setting of the second control unit.

[0016] In some embodiments, the first control module includes a second communication unit, which is used to communicate with the second control unit to receive control commands from the second control unit.

[0017] In some embodiments, the first control unit further includes:

[0018] The second control module is used to control the opening and closing of the first regulation unit, and to regulate the energy output of the first regulation unit.

[0019] In some embodiments, it also includes:

[0020] The second control unit includes a third control unit; the third control unit includes a second control coil; wherein the third control unit is configured to be placed inside the body of the test object, and the second control unit uses the coupling between the second control coil and the first coil to output energy to the first control module, and controls the stimulation degree of the first stimulation electrode through the first control module.

[0022] The third control unit includes a second control module connected to the second control coil, and the second control module is used to control the energy output of the second control coil.

[0023] The fourth control unit is used to set the energy output of the second control module. The second control module controls the energy output of the second control coil coupled to the stimulation part according to the output setting of the fourth control unit.

[0024] The above-mentioned technical solution of this application has the following beneficial technical effects:

[0025] In this embodiment, the stimulation part of the stimulation system is configured to be implanted at the stimulation site of the test substance, while the first control part is configured to be placed outside the test substance. That is, the stimulation system of this application adopts a distributed arrangement. Based on this arrangement, on the one hand, the production cost of the system can be significantly reduced. In use, the first control part of the stimulation system of this application is placed outside the body, and the stimulation part is placed at the stimulation site inside the body. Therefore, the requirements for the biocompatibility, battery safety, packaging tightness and overall reliability of the first control part are reduced, greatly reducing product costs and facilitating clinical promotion.

[0026] Secondly, the stimulation system of this application is characterized by its small size and high comfort. Based on this application, the first control unit is located externally, while the stimulation unit is located internally at the site to be stimulated. This allows the first control unit to control the stimulation level of the internally placed stimulation unit from the outside; that is, the stimulation unit of this application is a passive device. Based on this arrangement, this application differs from related technologies that require active control methods where the stimulation unit and control unit need to be connected by wiring. This application simplifies the complexity of the stimulation system. Furthermore, because the stimulation unit of this application does not require active connection wiring, its size is greatly reduced, thereby lowering production costs and significantly improving user comfort.

[0027] Thirdly, the potential risks of using the stimulation system of this application are reduced. Specifically, since the implanted part in the test object of the stimulation system of this application is a passive implant and the system complexity is reduced, the potential risks to the encapsulation and sealing of the stimulation part and battery safety are greatly reduced. In addition, since the stimulation source is from the external first control unit, the stimulation system can be quickly shut down in case of an emergency, greatly reducing the risk of use.

[0028] Fourthly, the stimulation system of this application is easy to upgrade. Specifically, based on the usage status of the stimulation system, upgrading the stimulation system of this application only requires upgrading the first control unit, thereby greatly reducing the difficulty of upgrading. Furthermore, due to the reduced cost of the stimulation system, the upgraded stimulation system can be directly replaced, further reducing the upgrade cost. Attached Figure Description

Further, the first stimulation electrode is placed at the stimulation site of the test object, which may include a patient.

[0045] In this embodiment, the stimulation unit 1 of the stimulation system is configured to be implanted at the stimulation site of the test substance, while the first control unit 2 is configured to be placed outside the test substance. That is, the stimulation system of this application adopts a distributed arrangement. Based on this arrangement, on the one hand, the production cost of the system can be significantly reduced. In use, the first control unit 2 of the stimulation system of this application is placed outside the body, and the stimulation unit 1 is placed at the stimulation site inside the body. Therefore, the requirements for the biocompatibility, battery safety, packaging tightness and overall reliability of the first control unit 2 are reduced, greatly reducing product costs and facilitating clinical promotion.

[0046] On the other hand, since the first control unit is configured for external use, the stimulation system of this application is easy to upgrade. Specifically, based on the stimulation system in use, upgrading the stimulation system of this application only requires upgrading the first control unit 2, thereby greatly reducing the difficulty of upgrading. Furthermore, due to the reduced cost of the stimulation system, the upgraded stimulation system can be directly replaced, further reducing the upgrade cost.

[0047] In some embodiments, a plurality of first control units 2 may be provided, each first control unit 2 being configured with a battery of a preset capacity.

[0055] The stimulation system of this application is characterized by its small size and high comfort. Based on this application, the first control unit 2 is disposed externally, and the stimulation unit 1 is disposed internally at the site to be stimulated. This allows the first control unit 2 to control the stimulation level of the stimulation unit 1 placed internally from the outside; that is, the stimulation unit 1 of this application is a passive device. Based on this arrangement, this application differs from the active control methods in related technologies that require a wiring connection between the stimulation unit 1 and the control unit, thus simplifying the complexity of the stimulation system. Furthermore, because the stimulation unit 1 of this application does not require an active connection wiring, its size is greatly reduced, thereby lowering production costs and significantly improving user comfort.

Parameter adjustment includes adjustments for current, waveform, and pulse, etc.

[0060] The potential risks associated with using the stimulation system of this application are reduced.
