[0002] With the development of science and technology and the progress of society, patients are eager to improve their quality of life through various treatment methods, and the application prospect of implantable pulse generating devices (such as stimulators) in medical devices is very broad. In order to obtain good stimulation treatment results, it is necessary to ensure that the actual implanted electrode type is consistent with the electrode type mark stored in the stimulator.

[0003] Currently, the electrode type stored in the stimulator is obtained by one-time input by a physician. However, this one-time input of the electrode type by the physician is completely dependent on the one-time input of the electrode type by the physician, and with the diversification of the electrode type, the physician may input an incorrect electrode type due to negligence or unfamiliarity with the product. Based on the incorrect electrode type, an invalid stimulation treatment plan is developed, which affects the treatment effect and even causes discomfort to the patient.

[0039] In order to make the personnel in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below by combining the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.

[0040] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings 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 the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" 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 have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] The technical field and related terms of the embodiments of the present application will be briefly described below.

[0042] Implantable medical systems include implantable neurostimulation systems, implantable cardiac electrostimulation systems (also known as cardiac pacemakers), implantable drug delivery systems (IDDS) and lead extension systems, etc. Implantable neurostimulation systems are, for example, deep brain stimulation systems (DBS), implantable cortical nerve stimulation systems (CNS), implantable spinal cord stimulation systems (SCS), implantable sacral nerve stimulation systems (SNS), implantable vagus nerve stimulation systems (VNS), etc.

[0043] Implantable neurostimulation systems include stimulators (i.e., implantable neurostimulators) implanted in patients and programming devices disposed outside the patients. That is, a stimulator is a medical device, or in other words, a medical device includes a stimulator. Related neuromodulation techniques mainly involve implanting electrodes (e.g., in the form of electrode leads) at specific locations (i.e., target sites) of a patient's tissue through stereotactic surgery, delivering electrical pulses to the target sites through the electrodes, and modulating the electrical activity and functions of corresponding neural structures and networks, so as to improve symptoms and relieve pain.

[0044] As an example, a DBS includes an IPG (Implantable Pulse Generator), an extension lead, and an electrode lead, with the IPG connected to the electrode lead through the extension lead. The IPG is implanted in a patient, for example, in the front of the patient's chest or other body parts.

[0045] As another example, a DBS includes an IPG and an electrode lead, with the IPG directly connected to the electrode lead. The IPG is implanted in a patient's head, for example, by slotting the patient's skull and then installing the IPG in the slot of the skull. In this case, the IPG can or can not partially protrude from the outer surface of the skull.

[0046] The IPG provides controllable electrical stimulation therapy (or electrical stimulation energy) to the tissue in the body by means of a sealed battery and circuitry in response to programming instructions sent by the programming device. The IPG delivers one or more controllable specific electrical stimulations to specific regions of the tissue in the body through the electrode lead.

[0047] In some embodiments, the extension lead is used in conjunction with the IPG as a transmission medium for electrical stimulation, delivering electrical stimulation generated by the IPG to the electrode lead.

[0048] 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 having various waveform shapes, frequencies, and amplitudes. Thus, the electrical stimulation in the form of a non-pulsed signal can be a continuous signal, which can have a sinusoidal waveform or other continuous waveform.

[0049] The electrode lead delivers the electrical stimulation received from the IPG or the extension lead to a specific region of the in-vivo tissue through a plurality of electrode contacts. The stimulator is provided with one or more electrode leads, which are unilateral or bilateral, and the electrode leads are provided with a plurality of electrode contacts, which can be arranged uniformly or non-uniformly in the circumferential direction of the electrode lead. As an example, the electrode contacts can be arranged in a 4-row 3-column array (a total of 12 electrode contacts) in the circumferential direction of the electrode lead. The electrode contacts can include stimulation electrode contacts and / or acquisition electrode contacts. The electrode contacts can have a sheet shape, a ring shape, a dot shape, etc.

[0050] In some embodiments, the in-vivo tissue to be stimulated can be the brain tissue of the patient, and the site to be stimulated can be a specific site of the brain tissue. When the patient has different types of diseases, the site to be stimulated is generally different, and the number of stimulation contacts (single source or multiple sources) used, the application of one or more specific electrical stimulations (single channel or multiple channels), and the stimulation parameters (values) are also different.

[0051] The embodiments of the present application are not limited to the types of diseases that can be applied, and can be applied to deep brain stimulation (DBS), spinal cord stimulation (SCS), sacral nerve stimulation, gastric stimulation, peripheral nerve stimulation, functional electrical stimulation, etc. The types of diseases that can be treated or managed by DBS include but are not limited to: convulsive diseases (e.g., epilepsy), pain, migraine, mental diseases (e.g., major depressive disorder (MDD)), bipolar disorder, anxiety disorder, post-traumatic stress disorder, mild depression, obsessive-compulsive disorder (OCD), behavioral disorder, emotional disorder, memory disorder, mental state disorder, movement disorder (e.g., essential tremor or Parkinson's disease), Huntington's disease, Alzheimer's disease, drug addiction, autism, or other neurological or psychiatric diseases and injuries.

[0052] In the embodiments of the present application, when the programming device and the stimulator establish a programming connection, the programming device can adjust one or more stimulation parameters of the stimulator (or one or more stimulation parameters of the pulse generator, different stimulation parameters correspond to different electrical stimulation), or the stimulator can sense the electrical physiological activity of the patient to acquire an electrical physiological signal, and the stimulation parameters of the stimulator can be continuously adjusted based on the acquired electrical physiological signal to realize closed-loop control (or adaptive adjustment) of the stimulation parameters.

[0053] The stimulation parameters can include at least one of the following: electrode contact identification (for example, 2# electrode contact and 3# electrode contact) for delivering electrical stimulation, frequency (for example, number of electrical stimulation pulse signals per unit time 1s, in Hz), pulse width (duration of each pulse, in μs), amplitude (generally expressed in voltage, i.e., intensity of each pulse, in V), timing (for example, can be continuous or burst, burst refers to 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), physician control upper and lower limits (range adjustable by the physician) and patient control upper and lower limits (range adjustable by the patient).

[0054] In some embodiments, the stimulation parameters of the stimulator can be adjusted in current mode or voltage mode.

[0055] The program control device can include a physician program control device (i.e., a program control device used by a physician) and / or a patient program control device (i.e., a program control device used by a patient). The physician program control device is, for example, a smart terminal device such as a tablet computer, a notebook computer, a desktop computer, a mobile phone, etc. equipped with program control software. The patient program control device is, for example, a smart terminal device such as a tablet computer, a notebook computer, a desktop computer, a mobile phone, etc. equipped with program control software, and can also be other electronic devices with program control functions (for example, a charger, an electrophysiological acquisition device, etc. with program control functions).

[0056] Embodiment one

[0057] Figure 1 A flowchart of an electrode type determination method is provided for the first embodiment of the present application. The present embodiment can be applied to the case where the implantable pulse generator determines the electrode type before generating pulses. The method can be executed by an electrode type determination device, which can be realized in the form of hardware and / or software, and can be configured in an electronic device. As shown in FIG. 1, the method includes: Figure 1

[0058] S110, in response to a user inputting an operation for a current electrode type of an implantable electrode on a user interface, triggering an impedance measurement operation between each contact combination in the implantable electrode.

[0059] In the embodiments of the present disclosure, the user can refer to the person who performs the current electrode type input operation. For example, the user can be a physician or an assistant. The user interface can refer to the user operation interface of the software built into the program control device. In the present embodiment, the user interface can be used to support the user to input the electrode type multiple times in order to realize the accuracy verification of the electrode type for each input. ​

[0060] The current electrode type input operation can refer to an operation of inputting, by a user, a current electrode type of an implanted electrode before an implanted electrode is implanted into a specified target area of a patient and before a program control device delivers a stimulation pulse instruction to an implanted pulse generator device, so that a doctor accurately selects a stimulation parameter according to the electrode type, such as selecting an electrode contact combination, a polarity setting, a parameter setting, and the like, thereby improving reliability and accuracy of delivering a stimulation pulse and improving a treatment experience of a patient. The current electrode type can refer to an electrode type input by a user in a current determination period or an electrode type that needs to be accurately determined in a current determination period. One current electrode type corresponds to one current determination period.

[0061] The electrode type can represent different electrode models, such as a type of an electrode contact on a stimulation end of an electrode (a ring-shaped electrode piece, a split electrode piece, and the like) and a distribution feature, which can be a size, a spacing, and the like of an electrode piece. Different neural tissues in a patient, such as a nucleus, can affect different indications, and different neural tissues have different morphologies and positions. Different electrode types need to be configured to accurately deliver electrical stimulation, thereby improving corresponding indications.

[0062] Each determination period includes at least steps S110 to S140 in the embodiment.

[0063] In the embodiment, the impedance measurement operation can refer to an operation of measuring impedance data of a biological tissue between contacts of an implanted electrode matched with an implanted pulse generator device (such as a stimulator) and analyzing the impedance data to obtain an impedance distribution feature. The impedance measurement operation can be an impedance measurement function implemented by executing a pre-written program code when the operation is triggered.

[0064] Specifically, after a user implants an electrode, the user inputs a current electrode type T of the implanted electrode through a user interface. In response to the user inputting an operation of a current electrode type of an implanted electrode through the user interface, an impedance measurement operation between each contact combination in the implanted electrode is triggered, that is, a stimulator software automatically triggers an impedance measurement program between each contact combination of the electrode once.

[0065] As an optional implementation manner of the embodiment, the implanted electrode includes at least one of a split electrode and a pure ring contact electrode; the split electrode includes a combination of a piece-shaped electrode piece and a ring-shaped electrode piece.

[0066] The implanted electrode can be a split electrode. The split electrode is different from a traditional ring electrode. By adopting different shapes of electrode pieces distributed on a cylinder, each electrode piece can be used as an independent contact, so that more accurate stimulation orientation can be provided, and treatment side effects can be reduced.

[0067] In the embodiments of the present disclosure, the segmented electrode can simultaneously include a plurality of sheet-shaped electrode sheets and ring-shaped electrode sheets (contacts), and the physical area of the sheet-shaped contacts is a fixed multiple smaller than that of the ring-shaped contacts. Therefore, under the condition that the conductivity of the external environment (usually tissue fluid) is the same, the impedance between the sheet-shaped contacts should be a corresponding multiple larger than that between the ring-shaped contacts. On this basis, it can be understood that the impedance distribution characteristic of the segmented electrode is that the impedance between the sheet-shaped contacts is a multiple larger than that between the ring-shaped contacts. The impedance distribution characteristic of the pure ring-shaped contact electrode does not have this characteristic. It can be seen that each type of implantable electrode has a corresponding unique impedance distribution characteristic, so as to distinguish each type of implantable electrode.

[0068] It should be noted that when the stimulator software is factory-fitted, the impedance data of each electrode type derived from the electrode physical design and combined with the factory-measured impedance data of each electrode type are pre-stored. The impedance distribution characteristic of each electrode type can be obtained by analyzing the impedance data.

[0069] S120, when the impedance measurement operation is executed, the current electrode type of the implantable electrode and the current impedance measurement result of the impedance measurement operation input by the user in the user interface are obtained; the implantable electrode is used to execute the pulse operation in combination with the stimulator.

[0070] In the embodiments of the present disclosure, the current impedance measurement result can refer to the current impedance distribution characteristic of the implantable electrode obtained by executing the impedance measurement operation. The current impedance distribution characteristic can refer to the impedance distribution characteristic obtained by analyzing the current impedance data of the implantable electrode measured in the current determination period.

[0071] Specifically, when it is monitored that the impedance measurement operation is executed, the current electrode type of the implantable electrode and the current impedance measurement result R obtained by executing the impedance measurement operation input by the user in the user interface are obtained.

[0072] S130, based on the association relationship between the preset electrode type and the impedance distribution characteristic and the current electrode type, the current impedance distribution characteristic corresponding to the current electrode type is determined.

[0073] In the embodiments of the present disclosure, the preset electrode type can refer to each electrode type distinguished in advance. The association relationship can be used to represent the impedance distribution characteristic uniquely corresponding to each electrode type. The current impedance distribution characteristic can refer to the impedance distribution characteristic corresponding to the current electrode type input by the user in the current determination period in the association relationship.

[0074] Specifically, the current impedance distribution characteristic associated with the current electrode type is queried in the association relationship between the preset electrode type and the impedance distribution characteristic.

[0075] S140, determine a current determination result of the current electrode type based on the preset determination rule, the current impedance distribution feature, and the current impedance measurement result.

[0076] In the embodiments of the present disclosure, the preset determination rule can refer to a manner of determining the accuracy of the current electrode type in combination with the current impedance distribution feature and the current impedance measurement result. In the embodiments of the present disclosure, the preset determination rule can be that the current impedance measurement result conforms to the current impedance distribution feature, or that the current impedance measurement result is consistent with the current impedance distribution feature, or that the similarity between the current impedance measurement result and the current impedance distribution feature exceeds a preset similarity threshold. The current determination result can refer to a determination result of whether the current electrode type input by the user is accurate.

[0077] Exemplarily, the preset determination rule can also be used to guide how to perform further determination operation when obtaining a preliminary determination result through the current impedance distribution feature and the current impedance measurement result, so as to obtain a more accurate current determination result. For example, when the current impedance measurement result does not conform to the current impedance distribution feature, the user can be prompted to re-input the current electrode type, and the impedance measurement operation is performed again to obtain the current impedance measurement result, so that the current electrode type re-input by the user and the current impedance measurement result measured again can be used for determination.

[0078] Specifically, the current impedance distribution feature and the current impedance measurement result are compared to determine a current comparison result corresponding to the current electrode type. If the current comparison result is that the features conform to each other, it is determined that the current determination result is that the electrode type input is correct. If the current comparison result is that the features do not conform to each other, it is determined that the current determination result is that the electrode type input is incorrect.

[0079] As an optional implementation manner of the embodiments of the present disclosure, the determination of the current determination result of the current electrode type based on the preset determination rule, the current impedance distribution feature, and the current impedance measurement result can specifically include: comparing the current impedance distribution feature and the current impedance measurement result to determine a current comparison result corresponding to the current electrode type; if the current comparison result is that the features conform to each other, it is determined that the current determination result of the current electrode type is that the electrode type input is correct; if the current comparison result is that the features do not conform to each other, it is determined that the current determination result is that the electrode type input is incorrect, and a re-determination prompt information is generated, and the re-determination prompt information is displayed through the user interface, so that the user can complete the current electrode type input operation for the implantable electrode on the user interface according to the re-determination prompt information.

[0080] In the embodiments of the present disclosure, the current comparison result can refer to a comparison result of whether the current impedance measurement result conforms to the current impedance distribution feature. The current comparison result can include: feature conformity and feature non-conformity. The re-determination prompt information can refer to electrode type input prompt information in the next determination period. The re-determination prompt information can be used to prompt the user on the user interface that the electrode type input in the current determination period is inaccurate and needs to be input again.

[0081] Specifically, the feature comparison is performed based on the current impedance distribution feature and the current impedance measurement result to obtain a feature similarity between the current impedance distribution feature and the current impedance measurement result. The current comparison result corresponding to the current electrode type is determined based on the feature similarity and a preset similarity threshold. For example, if the feature similarity is less than or equal to the preset similarity threshold, it is determined that the current comparison result is feature non-conformity; if the feature similarity is greater than the preset similarity threshold, it is determined that the current comparison result is feature conformity. According to the current comparison result, the current determination result corresponding to the current electrode type can be determined.

[0082] For example, if the current comparison result is feature conformity, it is determined that the current determination result of the current electrode type is that the electrode type input is correct. If the current comparison result is feature non-conformity, it is determined that the current determination result is that the electrode type input is incorrect and generates re-determination prompt information based on the current determination result. The re-determination prompt information is displayed through the user interface, so that the user completes the current electrode type input operation for the implantable electrode on the user interface according to the prompt content of the re-determination prompt information. The re-determination prompt information can be used to display the current determination result to the user and prompt the user to input again.

[0083] As an optional implementation manner of the embodiments of the present disclosure, generating the re-determination prompt information can specifically include: determining a recommended electrode type for the implantable electrode based on the association relationship between the preset electrode type and the impedance distribution feature and the current impedance measurement result; and generating the re-determination prompt information based on the current determination result and the recommended electrode type.

[0084] In the embodiments of the present disclosure, the recommended electrode type can refer to an electrode type that has a corresponding relationship with the current impedance measurement result. The recommended electrode type can be understood as an accurate electrode type determined from the preset corresponding relationship according to the current impedance measurement result. In the present embodiment, the re-determination prompt information can also include the recommended electrode type, so as to display the current determination result to the user and display the accurate electrode type, i.e., the recommended electrode type, recognized by the system to the user while prompting the user to input again, so that the user can refer to the recommended electrode type when filling in the current electrode type again, thereby further improving the accuracy of the current electrode type filling.

[0085] Specifically, the recommended electrode type corresponding to the current impedance measurement result is determined from the association between the preset electrode type and the impedance distribution characteristics. The current determination result and the recommended electrode type are filled into the respective corresponding positions in the preset prompt information generation template to generate the re-determination prompt information. Alternatively, a pre-written code or program for generating prompt information is executed, and the current determination result and the recommended electrode type are used to replace specific default information to generate the re-determination prompt information.

[0086] As an optional implementation of the embodiments of the present disclosure, before determining that the current determination result is an electrode type input error, the method further includes: determining the current determination result of the current electrode type based on a current comparison number corresponding to the current comparison result and a preset comparison number threshold.

[0087] In the embodiments of the present disclosure, the current comparison number can refer to the number of feature comparisons or the number of current comparison results before the implantable pulse generator produces a pulse. The preset comparison number threshold can refer to the maximum valid comparison number set in advance. The preset comparison number threshold can be understood as a foolproof design. The preset comparison number can be used to avoid the user from being trapped in an infinite repeated input dilemma due to system misjudgment or other unknown problems.

[0088] Specifically, if the current comparison result is that the characteristics are consistent, indicating that the user's input of the electrode type is accurate, and there is no need to determine the current determination result of the current electrode type based on the current comparison number corresponding to the current comparison result and the preset comparison number threshold, the current determination result of the current electrode type can be directly determined as an electrode type input correct.

[0089] Exemplarily, if the current comparison result is that the characteristics are inconsistent, indicating that there is a possibility that the user's input of the electrode type is not accurate, the current determination result of the current electrode type is determined based on the current comparison number corresponding to the current comparison result and the preset comparison number threshold, and according to the size relationship between the two.

[0090] The technical scheme of the embodiment of the present application responds to the user input operation of the current electrode type of the implantable electrode on the user interface, triggers the impedance measurement operation between each contact combination in the implantable electrode, obtains the current electrode type of the implantable electrode input by the user on the user interface and the current impedance measurement result of the impedance measurement operation when the impedance measurement operation is executed, and determines the current impedance distribution characteristic corresponding to the current electrode type based on the association relationship between the preset electrode type and the impedance distribution characteristic and the current electrode type. The current determination result of the current electrode type is determined based on the preset determination rule, the current impedance distribution characteristic, and the current impedance measurement result. By combining the electrode type input by the user and the impedance measurement result, and using the association relationship between the preset electrode type and the impedance distribution characteristic and the determination rule for automatic determination, whether the electrode type of the implantable electrode is correct can be accurately and conveniently verified. This process not only can correct the error electrode type input by the user in time, but also can ensure the accuracy of the electrode type input, thereby ensuring the correct matching of the stimulator and the electrode and improving the product efficacy and safety. By automatically triggering the impedance measurement and determining based on the preset rule, the manual intervention and manual verification steps are reduced, and the operation process is simplified, thereby improving the overall efficiency. The user only needs to input the electrode type, and the stimulator software can automatically complete the verification, thereby reducing the operation complexity. The determination relies on the objective impedance measurement data and the preset rule, thereby avoiding the error caused by the subjective judgment of the user and improving the reliability and consistency of the determination result. This is particularly important for medical devices, and can minimize the risk caused by operation errors.

[0091] As an optional implementation manner of the embodiment of the present application, after the current determination result is determined, the method further includes: if it is detected that the current determination result is that the electrode type input is incorrect, the current electrode type corresponding to the current determination result and the current impedance measurement result are cleared; and if it is detected that the current determination result is that the electrode type input is correct, the current electrode type corresponding to the current determination result and the current impedance measurement result are stored to update the association relationship between the electrode type and the impedance distribution characteristic.

[0092] Specifically, if it is detected that the current determination result is that the electrode type input is incorrect, the current electrode type and the current impedance measurement result corresponding to the current determination result of the electrode type input error are cleared to avoid performing the stimulation treatment according to the incorrect information. If it is detected that the current determination result is that the electrode type input is correct, it indicates that the user operates correctly and the current electrode type input by the user is accurate, and the current electrode type and the current impedance measurement result corresponding to the current determination result of the electrode type input correct are stored to ensure that the stored electrode type and impedance distribution characteristics are in an accurate corresponding relationship, so as to facilitate a doctor to accurately and reliably determine the electrode type after a new patient completes an implantation operation, thereby ensuring the efficacy of the stimulator matched with the electrode and reducing the risk of the stimulation treatment. In this embodiment, the doctor is allowed to perform the stimulation treatment only after the current electrode type and the current impedance measurement result are stored.

[0094] Figure 2 A flowchart of an electrode type determination method provided for Embodiment Two of the present application is described in detail below. The same or corresponding terms as those in the above embodiments are not described again here. As shown in FIG. 2, the method comprises the following steps. Figure 2

[0095] S210, in response to a user input operation of a current electrode type of an implantable electrode on a user interface, triggering an impedance measurement operation between each contact combination in the implantable electrode.

[0096] S220, when the impedance measurement operation is completed, obtaining the current electrode type of the implantable electrode input by the user on the user interface and a current impedance measurement result of the impedance measurement operation; the implantable electrode is used to perform a pulse operation matched with a stimulator.

[0097] S230, determining a current impedance distribution characteristic corresponding to the current electrode type based on an association relationship between preset electrode types and impedance distribution characteristics and the current electrode type.

[0098] S240, performing feature comparison based on the current impedance distribution characteristic and the current impedance measurement result to determine a current comparison result corresponding to the current electrode type.

[0099] S250, if the current comparison result is that the features are consistent, determining that the current determination result is that the electrode type input is correct.

[0100] S260, if the current comparison result is that the features are inconsistent, determining a current determination result of the current electrode type based on a current comparison number corresponding to the current comparison result and a preset comparison number threshold.​

[0101] S270, if the current comparison result corresponds to a current comparison number less than or equal to a preset comparison number threshold, it is determined that the current determination result is an electrode type input error, and a re-determination prompt information is generated, and the re-determination prompt information is displayed through the user interface, so that the user completes the current electrode type input operation for the implantable electrode on the user interface according to the re-determination prompt information.

[0102] Specifically, if the current comparison result corresponds to a current comparison number less than or equal to a preset comparison number threshold, indicating that the loop determination has not ended, it is determined that the current determination result is an electrode type input error, and a re-determination prompt information is generated, and the re-determination prompt information is displayed through the user interface, so that the user completes the current electrode type input operation for the implantable electrode on the user interface according to the re-determination prompt information.

[0103] S280, if the current comparison result corresponds to a current comparison number greater than a preset comparison number threshold, it is determined that the current determination result is an electrode type input correct.

[0104] In the embodiments of the present disclosure, if the current comparison result corresponds to a current comparison number greater than a preset comparison number threshold, indicating that the loop determination has ended, it is determined that the current determination result is an electrode type input correct.

[0105] Exemplarily, S240 to S280 can also be understood as the following process: according to the current impedance measurement result R, it is determined whether it conforms to the impedance distribution characteristics of the T type electrode. If it conforms to the characteristics, it is considered that the user input is correct, and the T and R are stored; if it does not conform to the characteristics, it is considered that the user input is incorrect, and a wireless instruction (equivalent to the re-determination prompt information) is prompted on the user interface, and the count value (which is consistent with the current comparison number) of the incorrect determination is incremented by one. After the incorrect determination (equivalent to the characteristics not conforming), if the incorrect count value is greater than 3, it is considered that the user insists on inputting correctly, and it is determined that the current determination result is an electrode type input correct. The upper limit number 3 is set to ensure the maximum authority of the user and avoid the situation that the software determination always conflicts with the user's expectation. If the incorrect count value does not exceed 3, the current electrode type T and the current impedance measurement result R of the previous user input are cleared, and a prompt is sent to the user interface through the wireless instruction, requiring the user to perform the electrode type input operation again, so as to perform the electrode type determination again.

[0106] The technical solution of this invention determines the current judgment result as an incorrect electrode type input if the current comparison count corresponding to the current comparison result is less than or equal to a preset comparison count threshold, and generates a re-judgment prompt. This re-judgment prompt is displayed through the user interface, allowing the user to complete the current electrode type input operation for the implantable electrode based on the re-judgment prompt. If the current comparison count corresponding to the current comparison result is greater than the preset comparison count threshold, the current judgment result is determined to be a correct electrode type input. By introducing a step-by-step verification and fault-tolerance mechanism, the risk of electrode type mismatch caused by a physician's one-time input error is systematically solved, thereby fundamentally ensuring the accuracy of the treatment plan and patient safety. When the comparison count does not exceed the threshold, the stimulator software does not simply report an error and stop, but generates a re-judgment prompt. This provides the physician with a clear opportunity to correct the error, guiding them to re-check and input the correct electrode type, transforming a simple operational error into a smooth correction process. Simultaneously, setting a comparison count threshold avoids the user being trapped in an infinite cycle of repeated input due to stimulator software misjudgment or other unknown problems. Confirming correct input after exceeding the threshold ensures the process can continue, balancing safety and operational efficiency.

[0107] The following are embodiments of the electrode type determination device provided in this invention. This device and the electrode type determination method of the above embodiments belong to the same inventive concept.
