Description

Technical Field

[0001] This application relates to the field of brain electrical device technology, and more particularly to a lead device. Background Technology

[0002] In related technologies, electroencephalography (EEG) is generally divided into electroencephalography (EEG), stereo-electroencephalography (SEEG), and electrocorticography (ECoG). EEG has fewer communication channels and a shorter wearing time. ECoG records electrical activity on the surface of the cerebral cortex and has fewer communication channels than SEEG, which covers the entire brain region but requires a longer implantation time. A typical single SEEG electrode has 8 to 16 communication channels; therefore, for adults, covering the entire brain region requires 10 to 16 SEEG electrodes, with a maximum of 256 communication channels. Common lead wires are cylindrical cables with 8 to 16 cores, matching the number of communication channels on the SEEG electrodes. When multiple lead wires are connected to a patient's brain, these wires are not only bulky and heavy but also long, requiring the patient to remain bedridden for extended periods after connection, hindering their daily care and increasing the burden on the patient and their family. In addition, the large number of communication channels increases the workload of the wiring personnel, and there is also the possibility of mis-insertion due to the tangled wires. Utility Model Content

[0003] This application provides a lead device that, by reducing the number of connecting wires in the lead device, at least partially solves the above-mentioned technical problems.

[0004] To achieve the above objectives, this application provides a lead device, comprising:

[0005] An adapter includes a body, a first connector and a second connector. The first connector is disposed on the body and configured to be connected to the EEG electrodes to receive EEG signals collected by the EEG electrodes. The second connector is disposed on the surface of the body opposite to the first connector and is connected to the first connector.

[0006] The busbar has a third connector that is connected to the second connector to receive EEG signals via the second connector.

[0007] Optionally, there are multiple first connectors arranged in an array; the number of plug holes is the same as the number of first connectors, and the plug holes are connected to the first connectors in a one-to-one correspondence.

[0008] Optionally, the adapter includes two second connectors, which are spaced apart and disposed on the same surface of the body.

[0009] Optionally, the second connector has communication channels, the number of which is greater than or equal to the number of the first connector.

[0010] Optionally, the third connector includes a first connector and a second connector spaced apart, each of which includes a communication channel.

[0011] Optionally, the communication channel includes a reference communication channel.

[0012] Optionally, the busbar has multiple third connectors and a main body with multiple comb teeth, each of which is provided with a third connector.

[0013] Optionally, the first connector is disposed at the root of the comb teeth, and the second connector is disposed at the head of the comb teeth.

[0014] Optionally, the main body also has a connecting part that is opposite to the multiple comb teeth. The connecting part is provided with a hub terminal, which is signal connected to multiple third connectors and configured to be signal connected to a signal processing device to aggregate the EEG signals received by the multiple third connectors to the signal processing device.

[0015] Optionally, the lead device further includes a selection component that is signal-connected to a third connector and configured to set at least one communication channel of any EEG electrode as a reference communication channel.

[0016] Optionally, the selection component is signal-connected to a third connector on one of the comb teeth located at the end of the comb teeth.

[0017] Optionally, the selection component has multiple selection switches, each of which is connected to a multiple first connector in a one-to-one correspondence. When the selection switch is configured to be in the open position, the communication channel of the EEG electrode connected to the first connector connected to the selection switch is a reference communication channel.

[0018] In this embodiment, by directly providing the first and second connectors on the body of the adapter, and with the second connector signal-connected to the first connector, the number of connecting wires between the first and second connectors is reduced, thereby reducing the weight of the lead device. This helps to alleviate discomfort for the patient after connecting the EEG electrodes to the lead device and increases the ease of patient movement after connection. Furthermore, placing the first and second connectors on opposite surfaces of the body helps to reduce their impact on each other's connection. Simultaneously, by providing a third connector on the busbar and connecting it to the second connector, the number of connecting wires between the adapter and the busbar is reduced, further reducing the weight of the lead device. This helps to alleviate discomfort for the patient after connecting the EEG electrodes to the lead wire and increases the ease of patient movement after connection.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] In related technologies, stereo-electroencephalography (SEEG) examinations require the use of lead wires to connect the EEG instrument to the EEG electrodes on the patient's head. SEEG covers the entire brain region and involves a relatively long implantation time. A single SEEG electrode typically has only 8 to 16 communication channels. For adults, covering the entire brain region requires 10 to 16 SEEG electrodes, with a maximum of 256 communication channels. Common lead wires are cylindrical cables with 8 to 16 cores. Therefore, to connect all the EEG electrodes to the EEG instrument, multiple lead wires are needed. These lead wires are not only bulky and heavy but also very long, preventing patients from getting out of bed after connection and forcing them to remain bedridden for extended periods, increasing the burden on patients and their families. In addition, the increased number of communication channels increases the workload of connecting EEG electrodes and leads. Furthermore, the tangled and intertwined leads may lead to misinsertion, affecting the examination results.

[0035] In view of the above-mentioned technical problems, this application provides a lead device in order to at least partially improve the above-mentioned technical problems.

[0036] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the lead device provided in the embodiments of this application. Figure 2 yes Figure 1 The provided exploded diagram of the lead device, Figure 3 yes Figure 1 A three-dimensional structural diagram of adapter 1 in the provided lead device. Figure 4 yes Figure 1 The provided lead device provides a three-dimensional structural schematic diagram of the adapter 1 from another perspective. The adapter 1 includes a body 11, a first connector 12, and a second connector 13. The first connector 12 is disposed on the body 11 and configured to be connected to the EEG electrodes to receive EEG signals collected by the EEG electrodes. The second connector 13 is disposed on the surface of the body 11 opposite to the first connector 12 and is connected to the first connector 12. The busbar 2 has a third connector 21, which is connected to the second connector 13 to receive EEG signals via the second connector 13.

[0037] In this embodiment, by directly providing the first connector 12 and the second connector 13 on the body 11 of the adapter 1, and with the second connector 13 signal-connected to the first connector 12, the length of the connecting line between the first connector 12 and the second connector 13 is reduced, thereby reducing the weight of the lead device. This helps to alleviate the discomfort caused to the patient after connecting the EEG electrodes to the lead device, and also helps to increase the convenience of the patient's movement after connecting the EEG electrodes to the lead device. Furthermore, by placing the first connector 12 and the second connector 13 on two opposite surfaces of the body 11, the influence of the first connector 12 and the second connector 13 on their mutual connection is reduced. Meanwhile, a third connector 21 is provided on the busbar 2 and the third connector 21 is connected to the second connector 13, so that the adapter 1 can be connected to the busbar 2, reducing the number of connecting wires between the adapter 1 and the busbar 2, thus reducing the weight of the lead device. This helps to reduce the discomfort caused to the patient after connecting the EEG electrodes to the lead wires (and the lead device of this application), and also helps to increase the convenience of the patient's activities after connecting the EEG electrodes to the lead wires (and the lead device of this application).

[0038] For example, when a patient undergoes a SEEG (stereotactic electroencephalography) examination, multiple EEG electrodes need to be precisely implanted into specific neural structures deep within the brain to record electrical activity in these areas. After implantation, the EEG electrodes are connected to an external EEG recording device for long-term recording of electrical activity in deep brain regions. Multiple EEG electrodes can record electrical activity in multiple brain regions, and common SEEG electrodes typically have multiple acquisition channels, generally 8 to 16. For adults, covering the entire brain region requires 10 to 16 EEG electrodes, resulting in a maximum of 256 acquisition channels. The adapter 1 of this application has multiple first connectors 12 for connecting to the EEG electrodes, such as... Figure 1 As shown, the adapter 1 has 16 first connectors 12. Therefore, by connecting multiple adapters 1 to the busbar 2 provided in this application, it can be connected to the EEG electrodes covering the whole brain region, and the EEG signals collected by the EEG electrodes of the whole brain region can be gathered to the busbar 2 to realize the collection of EEG signals from multiple communication channels.

[0039] It is understood that the examples of the number of first connectors 12 in the above embodiments are only for the purpose of understanding this application, and this application does not limit the specific number of first connectors 12 included in the adapter 1.

[0040] Understandably, reducing the number of connecting wires between the first connector 12 and the second connector 13, as well as between the adapter 1 and the busbar 2, also helps to reduce costs.

[0041] In some embodiments of this application, the first connector 12 is a pin.

[0042] Please continue reading. Figures 1 to 4 In some embodiments of this application, there are multiple first connectors 12, and the multiple first connectors 12 are arranged in an array.

[0043] In this embodiment, arranging the multiple first connectors 12 in an array can reduce the possibility of incorrect connections and help improve the accuracy of inspection results.

[0044] Please continue reading. Figures 1 to 4 In some embodiments of this application, the adapter 1 includes two second connectors 13, which are disposed at intervals on the same surface of the body 11.

[0045] Please continue reading. Figures 1 to 4 In some embodiments of this application, two second connectors 13 are disposed at both ends of the body 11, and in the projection plane perpendicular to the thickness direction of the body 11, the projection of the arrayed first connector 12 is located between the projections of the two second connectors 13.

[0046] In some embodiments of this application, the second connector 13 has communication channels, and the number of communication channels is greater than or equal to the number of the first connectors 12. This ensures that the EEG signals collected by each EEG electrode connected to the first connector 12 can be transmitted, thereby improving the accuracy and completeness of the examination results.

[0047] In some embodiments of this application, the third connector 21 includes a first connector 211 and a second connector 212 spaced apart, and the first connector 211 and the second connector 212 each include multiple communication channels.

[0048] In some embodiments of this application, the communication channel includes a reference communication channel.

[0049] During an electroencephalogram (EEG) examination, while ensuring that each first connector 12 has a connected communication channel, the remaining communication channels can be used as reference communication channels to eliminate background noise.

[0050] Please see Figure 5 , Figure 5 yes Figure 1 The provided schematic diagram of the three-dimensional structure of the busbar in the lead device shows that, in some embodiments of this application, the busbar 2 has a plurality of third connectors 21 and the busbar 2 also has a main body 22, the main body 22 has a plurality of comb teeth 221, and each comb tooth 221 is provided with a third connector 21.

[0051] In this embodiment, the main body 11 of the busbar 2 has a structure with multiple comb teeth 221, and each comb tooth 221 is provided with a third connector 21. When the lead device provided in this application is connected to the EEG electrode, the position of each comb tooth 221 can be adjusted according to the position of the EEG electrode, which facilitates the connection between the lead device and the EEG electrode and makes the lead device provided in this application applicable to more EEG electrode distributions.

[0052] In some embodiments of this application, the main body 22 of the busbar 2 is made of a flexible circuit board. This helps to expand the applicability of the lead device provided in this application. In addition, the flexible circuit board is lighter, which also helps to reduce the weight of the lead device.

[0053] Please continue reading. Figure 5 In some embodiments of this application, the first connector 211 is disposed at the root of the comb tooth portion 221, and the second connector 212 is disposed at the head of the comb tooth portion 221. This arrangement facilitates the establishment of the reference communication channel and improves the connection stability between the busbar 2 and the adapter 1.

[0054] Please continue reading. Figure 5In some embodiments of this application, the main body 22 also has a connecting portion 222 that is opposite to the plurality of comb teeth 221. The connecting portion 222 is provided with a hub terminal 23. The hub terminal 23 is signal connected to the plurality of third connectors 21 and is configured to be signal connected to a signal processing device to aggregate the EEG signals received by the plurality of third connectors 21 to the signal processing device.

[0055] In this embodiment, the main body 22 of the busbar 2 includes a connecting portion 222, and the connecting portion 222 is away from the comb portion 221, which facilitates the connection of the hub terminal 23 provided on the connecting portion 222 to the signal processing device. In addition, the hub terminal 23 is provided on the busbar 2 to collect the EEG signals collected by all EEG electrodes, thereby reducing the number of connecting lines between the busbar 2 and the signal processing device. This helps to reduce the weight of the components between the EEG electrodes and the signal processing device, thereby reducing patient discomfort and increasing the convenience of patient movement.

[0056] Please see Figure 6 and Figure 7 , Figure 6 yes Figure 1 A three-dimensional structural diagram of the selection component in the provided lead device. Figure 7 yes Figure 1 The provided lead device is shown in a three-dimensional structural schematic diagram from another perspective. In some embodiments of this application, the lead device further includes a selection component 3, which is signal-connected to a third connector 21 and configured to set at least one communication channel of any EEG electrode as a reference communication channel.

[0057] During an EEG examination, different types of EEG examinations establish different reference communication channels. For example, all EEG electrodes in SEEG are located in the cranium, and the communication channel of an unrelated lesion in the white matter area is usually selected as the reference communication channel. In order to distinguish the reference communication channel, the lead device provided in this application includes a selection component 3, which is used to select the reference communication channel.

[0058] In some embodiments of this application, the selection component 3 is signal-connected to a third connector 21 on one of the comb teeth 221 located at the end of the plurality of comb teeth 221. This arrangement facilitates the selection of a reference communication channel via the selection component 3 during examination, without affecting the connection between other adapters 1 and the EEG electrodes.

[0059] Please continue reading. Figure 6 and Figure 7In some embodiments of this application, the selection component 3 has a plurality of selection switches 31, which are connected one-to-one with a plurality of first connectors 12. When the selection switch 31 is configured to be in the open position, the communication channel of the EEG electrode connected to the first connector 12 connected to the selection switch 31 is a reference communication channel.

[0060] like Figure 6 and Figure 7 As shown, the selection component 3 includes a fourth connector 32 and a fifth connector 33. The fourth connector 32 is connected to the EEG electrode, the selection switch 31, and the fifth connector 33, and the fifth connector 33 is connected to the busbar 2. In this embodiment, the selection component 3 includes multiple fourth connectors 32, which are arranged in an array. Each EEG electrode has multiple communication channels. Therefore, by providing a corresponding selection switch 31 for each fourth connector 32, the reference communication channel can be precisely selected, thereby improving the accuracy of the examination results. Simultaneously, the fourth connector 32 is also connected to the fifth connector 33, enabling the EEG signals collected by the EEG electrode connected to the fourth connector 32 to be transmitted to the signal processing device via the fourth connector 32, the fifth connector 33, and the busbar 2.
