[0032] It should be noted that in the description and claims of the present invention and the above-mentioned accompanying drawings, the terms "first", "second", etc. are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including", "etc." and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0033] It should be noted that in the technical solution of the present disclosure, in terms of the collection, gathering, updating, analysis, processing, use, transmission, storage, etc. of user personal information, it complies with the provisions of relevant laws and regulations, is used for legal purposes, and does not violate public order and good customs. Necessary measures are taken for user personal information to prevent illegal access to user personal information data and to safeguard the security of user personal information and network security.

[0034] The following briefly describes the technical field and related terms of the embodiments of the present disclosure.

[0035] Implantable medical systems include implantable nerve stimulation systems, implantable cardiac electrical stimulation systems (also known as cardiac pacemakers), implantable drug delivery systems (Implantable Drug Delivery System, abbreviated as IDDS), and lead transfer systems, etc. Implantable nerve stimulation systems are, for example, deep brain stimulation systems (Deep Brain Stimulation, abbreviated as DBS), implantable cortical nerve stimulation systems (Cortical Nerve Stimulation, abbreviated as CNS), implantable spinal cord stimulation systems (Spinal Cord Stimulation, abbreviated as SCS), implantable sacral nerve stimulation systems (Sacral Nerve Stimulation, abbreviated as SNS), implantable vagus nerve stimulation systems (Vagus Nerve Stimulation, abbreviated as VNS), etc.

[0036] The implantable nerve electrical stimulation system includes a stimulator (i.e., implantable nerve stimulator) implanted in a patient's body and a programming device arranged outside the patient's body. That is to say, the stimulator is a medical device, or rather, the medical device includes the stimulator. The related nerve regulation technology mainly implants electrodes (the electrodes are in the form of electrode leads, for example) at specific parts (i.e., target points) of the tissue of an organism through stereotactic surgery, and sends electrical pulses to the target points through the electrodes to regulate the electrical activities and functions of the corresponding nerve structures and networks, thereby improving symptoms and relieving pain.

[0037] As an example, DBS includes an IPG (Implantable Pulse Generator, implantable pulse generator), an extension lead, and an electrode lead. The IPG is connected to the electrode lead through the extension lead. The IPG is implanted in the patient's body, for example, implanted in front of the patient's chest or other internal body parts.

[0038] As another example, DBS includes an IPG and an electrode lead, and the IPG is directly connected to the electrode lead. The IPG is implanted in the patient's head. For example, a slot is made in the patient's skull, and then the IPG is installed in the slot of the skull. In this case, the IPG may not protrude from the outer surface of the skull, or may partially protrude from the outer surface of the skull.

[0039] Among them, the IPG responds to the programming instructions sent by the programming device and provides controllable electrical stimulation therapy (or electrical stimulation energy) to the internal tissue by relying on a sealed battery and a circuit. The IPG delivers one or more channels of controllable specific electrical stimulation to a specific area of the internal tissue through the electrode lead.

[0040] In some embodiments, the extension lead is used in cooperation with the IPG as a transmission medium for electrical stimulation to transmit the electrical stimulation generated by the IPG to the electrode lead.

[0041] In some embodiments, the electrical stimulation can be delivered in the form of a pulsed signal or in the form of a non-pulsed signal. For example, the electrical stimulation can be delivered as a signal with various waveform shapes, frequencies, and amplitudes. Therefore, the electrical stimulation in the form of a non-pulsed signal can be a continuous signal, which can have a sine waveform or other continuous waveforms.

[0042] After receiving the electrical stimulation transmitted by the IPG or the extension wire, the electrode lead delivers the electrical stimulation to a specific area of the body tissue through multiple electrode contacts. The stimulator is provided with, for example, one or more electrode leads on one or both sides. Multiple electrode contacts are arranged on the electrode lead, and the electrode contacts can be evenly arranged or unevenly arranged in the circumferential direction of the electrode lead. As an example, the electrode contacts can be arranged in an array of 4 rows and 3 columns (a total of 12 electrode contacts) in the circumferential direction of the electrode lead. The electrode contacts can include stimulating electrode contacts and / or acquisition electrode contacts. The electrode contacts can be in the shape of, for example, flakes, rings, dots, etc.

[0043] In some embodiments, the stimulated body tissue can be the patient's brain tissue, and the stimulated site can be a specific site of the brain tissue. When the patient's disease types are different, the stimulated sites are generally different, and the number of stimulated contacts (single-source or multi-source), the application of one or more (single-channel or multi-channel) specific electrical stimulations, and the stimulation parameters (values) are also different.

[0044] The embodiments of the present disclosure do not limit the applicable disease types, which can be the disease types applicable to deep brain stimulation (DBS), spinal cord stimulation (SCS), sacral nerve stimulation, gastric stimulation, peripheral nerve stimulation, and functional electrical stimulation. Among them, the disease types that DBS can be used to treat or manage include but are not limited to: spastic diseases (such as epilepsy), pain, migraine, mental diseases (such as major depressive disorder (MDD)), bipolar disorder, anxiety disorder, post-traumatic stress disorder, dysthymia, obsessive-compulsive disorder (OCD), behavioral disorders, mood disorders, memory disorders, mental state disorders, movement disorders (such as essential tremor or Parkinson's disease), Huntington's disease, Alzheimer's disease, drug addiction, autism, or other neurological or psychiatric diseases and impairments.

[0045] In the embodiments of the present disclosure, when the programming device and the stimulator establish a programming connection, the programming device can be used to adjust one or more stimulation parameters of the stimulator (or one or more stimulation parameters of the pulse generator, and different stimulation parameters correspond to different electrical stimulations), and the stimulator can also sense the patient's electrophysiological activities to collect electrophysiological signals, and the stimulation parameters of the stimulator can be continuously adjusted through the collected electrophysiological signals to achieve closed-loop control (or adaptive adjustment) of the stimulation parameters.

[0046] Stimulation parameters may include at least one of the following: electrode contact identifiers for delivering electrical stimulation (e.g., electrode contact 2# and electrode contact 3#), frequency (e.g., the number of electrical stimulation pulse signals within a unit time of 1 s, with the unit of Hz), pulse width (the duration of each pulse, with the unit of μs), amplitude (generally expressed in voltage, i.e., the intensity of each pulse, with the unit of V), timing sequence (e.g., it can be continuous or bursty, and bursty refers to a discontinuous timing behavior composed of multiple processes), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode, and cyclic stimulation mode), upper and lower limits controlled by the doctor (the adjustable range by the doctor), and upper and lower limits controlled by the patient (the adjustable range by the patient).

[0047] In some embodiments, the stimulation parameters of the stimulator can be adjusted in current mode or voltage mode.

[0048] The programming device may include a doctor programming device (i.e., the programming device used by the doctor) and / or a patient programming device (i.e., the programming device used by the patient). The doctor programming device is, for example, an intelligent terminal device such as a tablet computer, a notebook computer, a desktop computer, a mobile phone, etc. equipped with programming software. The patient programming device is, for example, an intelligent terminal device such as a tablet computer, a notebook computer, a desktop computer, a mobile phone, etc. equipped with programming software. The patient programming device can also be other electronic devices with programming functions (e.g., a charger with programming functions, an electrophysiological acquisition device, etc.).

[0049] Figure 1 It is a flowchart of a method for storing electric field data according to an embodiment of the present invention. This embodiment is applicable to the situation of storing electric field simulation data and generating a target file in polygon file format. This method can be executed by an electric field data storage device, and the electric field data storage device can be implemented in the form of hardware and / or software.

[0050] As Figure 1 shown, the method of this embodiment may specifically include:

[0051] S110. Obtain an original file storing electric field simulation data; wherein, the format of the original file is text document format.

[0052] In this embodiment, the electric field simulation data may be simulation data of the electric field generated during the operation of an implantable medical system. The implantable medical system includes multiple electrodes. Correspondingly, the electric field simulation data may include the electrode contact coordinates of each electrode contact and the electric field intensity values corresponding to the electrode contact coordinates.

[0053] In specific implementation, after simulating the operation process of the implantable medical system through simulation software, the simulation data output by the simulation software is stored in text document format to generate an original file.

[0054] S120. Extract the electric field simulation data from the original file, store the electric field simulation data in the polygon file format, and obtain a file in the polygon file format.

[0055] In practical applications, as the number of electrode contacts increases, the storage space required for the electric field simulation data gradually increases. In order to reduce the space occupation while simplifying the operation process, the original file that meets the preset conditions can be determined and processed to effectively reduce the space occupation.

[0056] Specifically, the implementation method of extracting the electric field simulation data from the original file may include: when the storage space occupied by the original file meets the preset conditions, extract the electric field simulation data from the original file. Among them, the preset conditions may include at least one of the following: the current remaining space of the electric field data simulation system is less than the storage space; the storage space is greater than the preset space threshold.

[0057] It should be noted that the current remaining space is the space currently available for storing the electric field simulation data. When the current remaining space is less than the storage space occupied by the original file, the original file needs to be compressed to reduce the space occupation of the electric field simulation data, so as to store as much electric field simulation data as possible.

[0058] Or, when the storage space is greater than the preset space threshold, it means that the storage space is relatively large, and processing the original file has an obvious effect on reducing the space occupation. Therefore, the original file with a storage space greater than the preset space threshold can be processed. Among them, the preset space threshold can be the average value of the storage spaces of each stored file.

[0059] In a specific implementation, when the storage space occupied by the original file meets the preset conditions, the electric field simulation data in the original file can be extracted. It should be noted that the extraction operation of the electric field simulation data can be determined based on the file format of the original file. For example, if the file format of the original file is a text document format, the electric field simulation data in the original file can be extracted by reading line by line.

[0060] Further, the electric field simulation data is stored in accordance with the polygon file format. Among them, the polygon file format (Polygon File Format, abbreviated as PLY) is a three-dimensional file format for storing graphical objects described as a set of polygons. The file in the polygon file format includes point elements and face elements. Extract the electric field simulation data from the original file, and store the electric field simulation data in accordance with the polygon file format to obtain a polygon file format file, including: determining the electrode configuration information in the original file and the corresponding electric field strength distribution value of the electrode configuration information; creating an empty file in accordance with the polygon file format; writing the electrode configuration information and the electric field strength distribution value as point elements into the empty file to obtain a polygon file format file, and establishing a mapping relationship between the electrode configuration information and the polygon file format file.

[0061] Among them, the electrode configuration information includes at least one of the electrode contact combination and the configuration parameters of the electrode contacts. The configuration parameters include at least one of the polarity selection parameter and the pulse parameter of the electrode contacts. The pulse parameters include at least one of the amplitude, frequency, and pulse width; the empty file includes point elements and face elements.

[0062] In a specific implementation, the original file can be parsed to determine the electrode configuration information in the original file. Each electrode configuration information corresponds to an electric field strength distribution value. An empty file with the polygon file format can be created in advance. The empty file contains point elements and face elements. The electrode configuration information and the electric field strength distribution value are written into the empty file in the writing manner of point elements, so as to obtain a polygon file format file containing the electrode configuration information and the electric field strength distribution value. Through the point elements in the polygon file format file, a mapping relationship between the electrode configuration information and the polygon file format file can be established. In this embodiment, by writing the electrode configuration information and the electric field strength distribution value into the point elements in the created empty file, a polygon file format file can be generated quickly and accurately.

[0063] S130. Delete the face elements in the polygon file format file, and use the polygon file format file after deleting the face elements as the target file for storing the electric field simulation data.

[0064] It should be noted that since the electric field simulation situation can be reflected by the electrode contact coordinates and the corresponding electric field strength values, the face elements are invalid information for the electric field simulation situation. In order to further reduce the space occupation, the face elements in the polygon file format file can be deleted, thereby reducing the space occupation of the file. Use the polygon file format after deleting the face elements as the target file for storing the electric field simulation data, so that the target file can not only comprehensively store the electric field simulation data, but also effectively reduce the space occupation compared with the original file.

[0065] In this embodiment, the specific implementation of using the polygon file format file after deleting the face elements as the target file for storing the electric field simulation data is as follows: convert the file data in the polygon file format file after deleting the face elements into a binary format; use the polygon file format file obtained after the binary format conversion as the target file for storing the electric field simulation data.

[0066] For the file data in the polygon file format file, it can be saved in different formats to meet different data storage requirements. Specifically, the file data in the polygon file format after deleting the face elements can be converted into ASCII (American Standard Code for Information Interchange) code. Or, the file data in the polygon file format after deleting the face elements can be converted into a binary format for saving.

[0067] In this embodiment, since the binary format can save file volume compared with the ASCII code. To better meet the requirement of saving data storage space, the file data in the polygon file format file after deleting the face elements can be converted into a binary format, and the polygon file format file obtained after the binary format conversion is used as the target file.

[0068] In this embodiment, by converting the file data into a binary format, the file data is compressed, further reducing the occupation of data storage space and realizing file lightweight.

[0069] The technical solution of the embodiment of the present invention includes: obtaining an original file storing electric field simulation data, where the format of the original file is a text document format; extracting the electric field simulation data from the original file, storing the electric field simulation data in the polygon file format to obtain a polygon file format file; since the file in the polygon text format occupies less space than the text document format, the requirement for the storage space of the electric field simulation data is reduced; and deleting the face elements in the polygon file format file, using the polygon file format file after deleting the face elements as the target file for storing the electric field simulation data, which further reduces the space occupation of the target file and is beneficial to reducing the storage cost and space requirement of the electric field simulation data.

[0070] Figure 2 It is a flowchart of another method for storing electric field data provided by the embodiment of the present invention. Based on the above embodiment, this embodiment can also render the electric field simulation data based on the target file to display the electric field distribution image. The explanations of the same or corresponding terms as those in the above embodiments are not repeated here. For exampleFigure 2 As shown, the method includes:

[0071] S210. Obtain the original file storing the electric field simulation data; wherein, the format of the original file is a text document format.

[0072] S220. Extract the electric field simulation data from the original file, and store the electric field simulation data in the polygon file format to obtain a polygon file format file.

[0073] S230. Delete the face elements in the polygon file format file, and use the polygon file format file after deleting the face elements as the target file for storing the electric field simulation data.

[0074] S240. In the case of receiving an image rendering request sent by the display terminal, determine the target file corresponding to the image rendering request as the file to be rendered; read the data to be rendered stored in the file to be rendered, and send the data to be rendered to the display terminal, so that the display terminal renders the data to be rendered and displays the electric field distribution image corresponding to the data to be rendered on the display interface.

[0075] In practical applications, in order to better meet the actual needs of users and comprehensively and intuitively understand the electric field distribution corresponding to the electric field simulation data, the electric field simulation data can be rendered.

[0076] In specific implementation, the electric field simulation data can be the simulation data of the electric field generated during the operation of the implantable medical system. In order to facilitate users to understand the operation of the implantable medical system, it is usually necessary to render the electric field simulation data to display the rendered image.

[0077] Specifically, in response to the image rendering request sent by the display terminal, the target file corresponding to the image rendering request can be used as the file to be rendered to obtain the rendered image. Among them, the display terminal can be the doctor display terminal corresponding to the implantable medical system, and the image rendering request is generated by means of gesture control, voice control or touch screen control of the doctor display terminal. The image rendering request includes information such as the information of the file to which the electric field data to be rendered belongs, for example, file identification and file name, etc.

[0078] In the case of receiving an image rendering request sent by the display terminal, the file identification or file name requested by the image rendering request can be determined, and the target file matching the requested file identification or file name is obtained from the pre-established database as the file to be rendered.

[0079] In this embodiment, the file data in the file to be rendered can be read as the data to be rendered. Among them, the data to be rendered can be electric field simulation data, including electrode contact coordinates and the corresponding electric field strength values of the electrode contact coordinates. By sending the data to be rendered to the display terminal, the display terminal performs a rendering operation on the data to be rendered, thereby generating an image corresponding to the data to be rendered. In order to reflect the working effect of the implantable medical system, through the rendering operation, an electric field distribution image corresponding to the data to be rendered can be displayed on the display interface of the display terminal. Figure 3 is an interface display diagram after data rendering provided according to an embodiment of the present invention; as Figure 3 shown, it shows an electric field distribution image corresponding to the electric field simulation data, which can effectively display the distribution of the electric field information corresponding to the electric field simulation data.

[0080] In this embodiment, through the received image rendering instruction, the electric field simulation data of the target file that the user needs to understand can be rendered to more clearly and intuitively reflect the electric field distribution of the electric field simulation data, and display the electric field distribution image.

[0081] In this embodiment, the implementation method of reading the data to be rendered stored in the file to be rendered can be: calling a format parser for parsing the file content according to the reading rules of the polygon file format, so as to parse the file content of the file to be rendered through the format parser, and using the parsed data as the data to be rendered.

[0082] In a specific implementation, a format parser for reading content according to the reading rules of the polygon file format can be pre-encapsulated. When the file to be rendered is detected, the format parser can be called to read the file content of the file to be rendered according to the reading rules, without reading line by line, improving the reading efficiency, and using the parsed data as the data to be rendered.

[0083] In this embodiment, the file content of the polygon file format is read through the pre-encapsulated format parser, so that the reading operation can be completed conveniently and quickly, so as to improve the accuracy and convenience of reading the file content of the polygon file format.
