Background technique

Implantable neurostimulation systems mainly include implanted stimulators and externally programmed devices. Neuromodulation technology is mainly to implant electrodes into specific structures (that is, targets) in the body through stereotaxic surgery, and the stimulator implanted in the patient's body sends electrical pulses to the target through the electrodes to regulate the electrical activity and electrical activity of the corresponding neural structures and networks. Its function to improve symptoms and relieve pain.

The existing program-controlled equipment is not user-friendly in terms of timing stimulation. Generally speaking, the stimulation time corresponding to the stimulation program is set by the manufacturer and cannot be adjusted. For example: 8:00 am to 8:00 pm corresponds to a stimulation program with a larger stimulation pulse amplitude, and automatically switches to a stimulation program with a smaller stimulation pulse amplitude during the rest of the time.

Based on the stimulation program and its timing information, control instructions are generated and sent to the stimulator to cause the stimulator to generate and apply electrical stimulation to the target tissue of the patient in accordance with the control instructions.

The beneficial effects of the technical solution are: on the one hand, the user can flexibly set the timing information corresponding to the stimulation program.

Compared with the method of step-by-step adjustment through key operation and the method of directly inputting specific values, the user's operation steps are greatly reduced, and the timing information is greatly reduced. The settings are quicker and more convenient, which further enhances the user experience.

In some optional embodiments, the controller is configured to obtain timing information for the stimulation program in the following manner:

The beneficial effect of the technical solution is that the target programming mode can indicate one or more stimulation programs, and the user can set the timing information of the target programming mode to synchronize the timing information of multiple stimulation programs to meet the needs of different patients in practical applications. .

In some optional embodiments, the controller is further configured to obtain timing information for each of the stimulation programs in the following manner:

When the target programming mode indicates a single stimulation program, determining the timing information of the target programming mode as the timing information of the single stimulation program;

When the target programming mode indicates a plurality of stimulation programs, determining the timing of each stimulation program based on timing information of the target programming mode, the duration of each of the stimulation programs, and the ordering of the plurality of stimulation programs timing information.

When it is detected that the overlapping time period is a part of the second time period, the remaining time period is obtained by removing the overlapping time period from the second time period, and the existing program is updated with the remaining time period Timing information for the mode.

The beneficial effect of the technical solution is: when the timing information of the target program control mode and the timing information of the existing program control mode that have been set before conflict, the timing information of the target program control mode shall prevail, and the timing information of the existing program control mode shall be regarded as the criterion. The corresponding second time period is deduplicated, and the timing information of the existing program control mode is updated, and the timing information of the target program control mode does not change, which can reflect the user's adjustment intention and conform to the user's use preference.

In some optional embodiments, the controller is further configured to:

When it is detected that the coincident time period is the whole of the second time period, the timing information of the existing program control mode is removed.

In some optional embodiments, the controller is further configured to:

Use the touch screen to display a dial, and display two slidable sliders in the circumferential direction of the dial, and the positions of the two sliders are respectively used to indicate the start time and the end time corresponding to the target program control mode;

The sliding operation is an operation of sliding one slider or an operation of sliding two sliders.

The beneficial effect of the technical solution is that: by setting the dial and the slider, the start time and the end time can be clearly and intuitively reflected by the position of the slider on the dial, which is convenient for the user to set timing information.

In some optional embodiments, the controller is further configured to obtain the timing information of the target programming mode in the following manner:

Detecting whether the operation of sliding each slider is valid, to obtain valid operations in the sliding operation;

Timing information for the target programming mode is obtained based on the valid operation.

The beneficial effect of the technical solution is that the sliding operation can be an operation of sliding one slider, or an operation of sliding two sliders. When the user slides a slider and the operation of sliding the slider is determined to be valid, The timing information of the target program control mode is obtained according to the position of the slider; when the user slides two sliders, as long as the operation of sliding one of the sliders or the two sliders is determined to be valid, according to the position of the slider corresponding to the valid operation Get the timing information of the target programmed mode.

That is to say, regardless of sliding one slider or sliding two sliders, as long as there is an effective operation, the timing information of the target program control mode can be obtained, which reduces the operation difficulty of the user's timing setting. For users with poor hand control ability, Especially for Parkinson's patients, when sliding two sliders, even if only the operation of sliding one of the sliders is determined to be valid, the timing information can be set, which can give users positive feedback and greatly reduce the user's psychology. burden and improve the user experience.

In some optional embodiments, the controller is further configured to obtain the timing information of the target programming mode in the following manner:

It is respectively detected whether the operation of sliding each slider is valid, and when the operation of sliding each slider is valid, the timing information of the target program control mode is acquired.

The beneficial effect of the technical solution is that: when the user slides a slider, and the operation of sliding the slider is determined to be valid, the timing information of the target program control mode is obtained according to the position of the slider; when the user slides two sliders , only the operation of sliding the two sliders is determined to be valid, and the timing information of the target program control mode is obtained according to the positions of the two sliders.

That is to say, regardless of sliding one slider or sliding two sliders, the timing information of the target program control mode is obtained only when the operations corresponding to all the sliders being slid are valid. When the operation of a slider is judged to be valid, the timing information cannot be set. For patients with depression, bipolar disorder, etc., it is easy to act impulsive and irrational. The program-controlled device of the present application has a certain threshold in the setting of timing information, and only the user can operate stably in a rational and calm state. The timing information can be set to ensure the safety of the user's life. At the same time, for children and other people who use the program-controlled equipment unintentionally, the timing information of the target program-controlled mode can be obtained only when the operations corresponding to all the sliders being slid are valid, which can be further avoided. wrong operation.

In some optional embodiments, a slider being slid is used as the target slider, and the process of detecting whether the operation of sliding the target slider is valid is as follows:

Based on the operation of sliding the target slider, obtain the sliding path corresponding to the target slider, and detect whether the position of each track point of the sliding path is in a preset sliding area;

When the position of at least one trajectory point of the sliding path is not in the preset sliding area, determining that the operation of sliding the target slider is invalid;

When the positions of each track point of the sliding path are in the preset sliding area, it is determined that the operation of sliding the target slider is valid.

The beneficial effect of the technical solution is: by detecting the position of each track point of the sliding path to determine whether the operation of the sliding target slider is valid, and only when the position of each track point is in the preset sliding area, it is determined to slide the target sliding The operation of the block is valid, and then the timing information is obtained, thereby avoiding user misoperation.

In some optional embodiments, the controller is further configured to detect whether the operation of sliding the target slider is valid in the following manner:

When the positions of each track point of the sliding path are in the preset sliding area, a reference path corresponding to the sliding path is obtained based on the starting point, the ending point and the path direction of the sliding path, and the reference path is a preset sliding path. Suppose a part of the circumferential path and the path direction of the reference path is determined by the path direction of the sliding path, and the preset circumferential path is in the preset sliding area;

Detecting whether the similarity between the sliding path and the reference path is not less than a preset similarity threshold;

When the similarity is less than the preset similarity threshold, it is determined that the operation of sliding the target slider is invalid;

When the similarity is not less than the preset similarity threshold, it is determined that the operation of sliding the target slider is valid.

The beneficial effect of the technical solution is that: the two-stage detection process is used to judge whether the sliding operation is valid, and the timing information of the target program control mode is obtained only when the sliding operation is judged to be valid. When the positions are all in the preset sliding area, it is not directly determined that the sliding operation is valid, but the second stage of detection is entered. When the detected similarity is not less than the preset similarity threshold, the sliding operation is determined to be valid, and then the timing information is obtained. The two-stage detection process can play the role of double insurance, preventing users from setting unreasonable timing information due to misoperation, and ensuring the safety of patients' lives.

Specifically, in the first stage, it is detected whether the position of each trajectory point of the sliding path is in the preset sliding area, and when it is detected that the position of each trajectory point of the sliding path is in the preset sliding area, it indicates that The user may have the intention to set the timing information, and then enter the second stage; in the second stage, based on the starting point, end point and path direction of the sliding path, the reference path corresponding to the sliding path is obtained, and the similarity between the sliding path and the reference path is obtained. It is detected whether the similarity is not less than the preset similarity threshold, and when the similarity is not less than the preset similarity threshold, it can be determined that the sliding operation is not a wrong operation, and the sliding operation is valid.

Obtaining the validity judgment result through the two-stage detection process is not the ultimate goal. The ultimate goal is to judge the real intention of the user's operation according to the validity judgment result, so that the set timing information conforms to the user's psychological expectation, thereby improving the user's use experience.

In some optional embodiments, the controller is further configured to obtain the reference path in the following manner:

Find the point closest to the starting point of the sliding path on the preset circular path as the starting point of the reference path;

Find the point closest to the end point of the sliding path on the preset circular path as the end point of the reference path;

Based on the path direction of the sliding path, the path between the start point and the end point of the reference path is taken from the preset circumferential path as the reference path.

The beneficial effect of the technical solution is that: the point on the preset circular path that is closest to the starting point of the sliding path is used as the starting point of the reference path, and the point on the preset circular path that is closest to the end point of the sliding path is used as the end point of the reference path, Intercept the path from the start point to the end point of the reference path in the preset circular path along the path direction of the sliding path as the reference path, the obtained reference path is more suitable for the sliding path, and it is reasonable to obtain the corresponding timing information according to the reference path. , which can truly reflect the user's intention when setting the timing information.

In some optional embodiments, the two sliders include a start slider for indicating a start moment and an end slider for indicating an end moment;

Wherein, the vector of the center of the dial pointing to the start slider is taken as the first vector, and the vector of the center of the dial pointing to the end slider is taken as the second vector, the first vector along the direction of the dial The included angle from the clockwise direction to the second vector does not exceed 180 degrees.

The beneficial effect of the technical solution is that the clockwise direction of the dial is selected as the extending direction from the start time to the end time, and the time period corresponding to the start time to the end time does not exceed the time period corresponding to half the dial.

For example: it is specified that the time period around the dial is 24 hours. When the time corresponding to the positions of the two sliders is 23:00 and 1:00 in turn, determine the slider corresponding to 23:00 as the start slider, and 1:00 The corresponding slider is the end slider, and the determined time period is from 23:00 of the current day to 1:00 of the next day (the duration is 2 hours), not from 1:00 of the current day to 23:00 of the current day ( The duration is 22 hours), which is more in line with the user's operating habits.

In some optional embodiments, the controller is further configured to:

Use the touch screen to display the clock information of the stimulator and the clock information of the program-controlled device;

The touch screen is used to receive a synchronization operation, and in response to the synchronization operation, the clock information of the stimulator and the clock information of the program-controlled device are synchronized.

The beneficial effect of the technical solution is that: by synchronizing the clock information of the stimulator and the clock information of the program-controlled device, the deviation of the timing information setting caused by the asynchronous clock information of the stimulator and the program-controlled device can be avoided.

In some optional embodiments, the controller is further configured to:

Referring to FIG. 2, in some optional embodiments, the step S101 may include steps S201 to S202.

Step S201: using the touch screen to receive the sliding operation, and in response to the sliding operation, obtain timing information of a target programming mode, where the target programming mode is used to indicate at least one of the stimulation programs;

Step S202: Determine timing information of each stimulation program based on the target programming mode and its timing information.

The application does not limit the number of stimulation programs indicated by the target programming mode, which can be 1, 3, 6 or 8.

Thus, the target programming mode can indicate one or more stimulation programs, and the user can set the timing information of the target programming mode to synchronize the timing information of multiple stimulation programs to meet the needs of different patients in practical applications.

In another specific application, when the target programming mode indicates a plurality of stimulation programs, the timing information of the target programming mode is equally distributed or distributed according to a preset ratio to determine the timing information of each stimulation program.

For example, the target programming mode indicates the stimulation program b, the stimulation program c, and the stimulation program d in sequence. The timing information of the target programming mode is 15:00 to 16:00, then the timing information of stimulation program b is 15:00 to 15:20, the timing information of stimulation program c is 15:20 to 15:40; the timing information of stimulation program d is 15:20 to 15:40.

When the target programming mode indicates a single stimulation program, determining the timing information of the target programming mode as the timing information of the single stimulation program;

When the target programming mode indicates a plurality of stimulation programs, determining the timing of each stimulation program based on timing information of the target programming mode, the duration of each of the stimulation programs, and the ordering of the plurality of stimulation programs timing information.

Therefore, when the target programming mode indicates a single stimulation program, the form of electrical stimulation provided is single in the time period corresponding to the timing information of the target programming mode; when the target programming mode indicates multiple stimulation programs, it can be During the time period corresponding to the timing information of the target programming mode, electrical stimulation is provided in sequence using a plurality of stimulation programs.

In a specific application, the target programming mode indicates the stimulation program e, the stimulation program f, and the stimulation program g in sequence. The duration of stimulation program e is 120s, the duration of stimulation program f is 90s, the duration of stimulation program g is 150s, and the stimulation period of the target programming mode is 120s+90s+150s=360s.

The timing information of the target programming mode is from 15:00 to 16:00, then from 15:00 to 16:00, electrical stimulation can be applied to the patient for 10 stimulation cycles. In each stimulation cycle (0 to 360s), The timing information of stimulation program e is 0 to 120 s, the timing information of stimulation program f is 120 to 210 s, and the timing information of stimulation program g is 210 to 360 s.

In a specific application, no stimulation (ie, the parameter value of the stimulation parameter is zero) can also be used as a stimulation method, in the form of, for example, a stimulation program bye.

For example, the target programming mode instructs the stimulation program h, the stimulation program j and the stimulation program bye in sequence.

Referring to FIG. 3 , in some optional embodiments, the method may further include steps S301 to S302.

Step S301: when the first time period corresponding to the timing information of the target program control mode and the second time period corresponding to the preset timing information of the existing program control mode overlap, determine the overlapping time period;

Step S302: when it is detected that the overlapping time period is a part of the second time period, remove the overlapping time period from the second time period to obtain a remaining time period, and use the remaining time period to update the Timing information for programmed mode is available.

Thus, when there is a conflict between the timing information of the target program control mode and the timing information of the existing program control mode that has been set before, the timing information of the target program control mode shall prevail, and the second time corresponding to the timing information of the existing program control mode The time period is deduplicated, the timing information of the existing program control mode is updated, and the timing information of the target program control mode does not change (the user's setting result is maintained), which can reflect the user's adjustment intention and conform to the user's usage preference.

In a specific application, the first time period corresponding to the timing information of the target program control mode is 2:00 to 5:00, the second time period corresponding to the timing information of the existing program control mode is 4:00 to 7:00, The overlapping time period is from 4:00 to 5:00, and the overlapping time period is part of the second time period. After removing the overlapping time period from the second time period, the remaining time period 5:00 to 7:00 is obtained, and the remaining time period is used to update Timing information of the existing program control mode, so that the timing information of the existing program control mode indicates 5:00 to 7:00.

Referring to FIG. 4, in some optional embodiments, the method may further include step S303.

Step S303: when it is detected that the overlapping time period is the entire second time period, remove the timing information of the existing program control mode.

Thus, when the overlapping time period is the entire second time period, the timing information of the existing program control mode can be removed, and the program control mode corresponding to the second time period is changed from the existing program control mode to the target program control mode.

In a specific application, the first time period corresponding to the timing information of the target program control mode is 2:00 to 5:00, and the second time period corresponding to the timing information of the existing program control mode is 4:00 to 5:00, The coincidence time period is from 4:00 to 5:00, and the coincidence time period is the whole of the second time period, and the timing information of the existing program control mode is removed.

In some embodiments, when it is detected that the coincident time period is the whole of the second time period, the timing information of the existing programmed control mode may be adjusted (in the form of a delay, etc.), so that the first time period is the same as the adjusted time period. The second time period does not overlap. In this case, the timing duration of the existing programmed mode does not change.

In a specific application, the first time period corresponding to the timing information of the target program control mode is 2:00 to 5:00, and the second time period corresponding to the timing information of the existing program control mode is 4:00 to 5:00, The coincidence time period is 4:00 to 5:00, and the coincidence time period is the whole of the second time period, then adjust the timing information of the existing program control mode. After adjustment, the second time period is 5:00 to 7:00.

In some optional embodiments, the method may further include:

Use the touch screen to display a dial, and display two slidable sliders in the circumferential direction of the dial, and the positions of the two sliders are respectively used to indicate the start time and the end time corresponding to the target program control mode;

The sliding operation is an operation of sliding one slider or an operation of sliding two sliders.

Therefore, by setting the dial and the slider, the start time and the end time can be clearly and intuitively reflected by the position of the slider on the dial, which is convenient for the user to set timing information.

The application does not limit the shape of the slider, and the shape of the slider may be any one of a circle, a triangle, a rectangle, and a polygon.

Referring to FIG. 5 , in a specific application, the time span represented by one week of the dial may be 6 hours, 8 hours, 12 hours or 24 hours.

The circumference of the dial can be set with multiple scales, for example, four scales can be set along the clockwise direction of the dial, and the four scales represent the time 0:00 (24:00), 6:00, 12: 00 and 18:00.

In some embodiments, the dial is sequentially provided with N scales in a clockwise direction, and the difference between the moment corresponding to the kth scale and the moment corresponding to the k-1th scale corresponds to the k+1th scale The difference between the moment of and the moment corresponding to the kth scale is different. N is an integer greater than 2, and k is an integer greater than 1 and less than N.

For example: the dial is set with 6 scales in turn in a clockwise direction, and the times represented by these 6 scales are 0:00, 8:00, 14:00, 19:00, 21:00 and 23:00.

In some embodiments, the two sliders may include a start slider for indicating a start time and an end slider for indicating an end time, wherein the setting range of the start time and the end time is 0 on the same day : 00 to 23:59 (or 0:00:00 to 23:59:59), and the sliders corresponding to the start slider and the end slider are constant and will not change due to the user's sliding operation.

In a specific application, the start slider and the end slider may be displayed in the same color and/or the same shape.

In another specific application, the start slider and the end slider can be displayed in different colors and/or different shapes respectively.

For example, the start slider is displayed as a blue slider a on the touch screen, the end slider is displayed as a yellow slider b on the touch screen, the time corresponding to the position of the slider a is 8:00, and the time corresponding to the slider b If it is 22:00, the start time is 8:00 of the day, and the end time is 22:00 of the day.

For example, a circular arc area (with a certain width in the radial direction) corresponding to the timing information of the target program control mode can be displayed in green. The position corresponding to the end time of , is the end point, which points from the start point to the end point, thereby intuitively displaying the time period corresponding to the timing information of the target program control mode.

In some embodiments, after the setting of the timing information of a program control mode is completed, the timing information of the program control mode is the preset timing information of the existing program control mode.

For example, the arc area (with a certain width in the radial direction) corresponding to the timing information of the existing program control mode can be displayed in red. The position corresponding to the end time of the program control mode is the end point, and the starting point points to the end point, so that the time period corresponding to the timing information of the existing program control mode is visually displayed, and the user is reminded that the time period corresponding to the arc area has a corresponding time period. There is a program control mode.

Referring to FIG. 6 , in some optional embodiments, the step S201 may include steps S401 to S402.

Step S401: Detecting whether the operation of sliding each slider is valid, to obtain valid operations in the sliding operation;

Step S402: Acquire timing information of the target program control mode based on the valid operation.

Therefore, the sliding operation may be an operation of sliding one slider, or an operation of sliding two sliders. When the user slides a slider and the operation of sliding the slider is determined to be valid, according to the operation of the slider The timing information of the target program control mode is obtained from the position; when the user slides two sliders, as long as the operation of sliding one of the sliders or the two sliders is determined to be valid, the target program control mode is obtained according to the position of the slider corresponding to the valid operation. timing information.

That is to say, regardless of sliding one slider or sliding two sliders, as long as there is an effective operation, the timing information of the target program control mode can be obtained, which reduces the operation difficulty of the user's timing setting. For users with poor hand control ability, Especially for Parkinson's patients, when sliding two sliders, even if only the operation of sliding one of the sliders is determined to be valid, the timing information can be set, which can give users positive feedback and greatly reduce the user's psychology. burden and improve the user experience.

In some optional embodiments, the step S201 may include:

It is respectively detected whether the operation of sliding each slider is valid, and when the operation of sliding each slider is valid, the timing information of the target program control mode is acquired.

Therefore, when the user slides one slider, and the operation of sliding the slider is determined to be valid, the timing information of the target program control mode is obtained according to the position of the slider; when the user slides two sliders, only two sliders are slid The operations of the sliders are all determined to be valid, and the timing information of the target program control mode is obtained according to the positions of the two sliders.

That is to say, regardless of sliding one slider or sliding two sliders, the timing information of the target program control mode is obtained only when the operations corresponding to all the sliders being slid are valid. When the operation of a slider is judged to be valid, the timing information cannot be set. For patients with depression, bipolar disorder, etc., it is easy to act impulsive and irrational. The program-controlled device of the present application has a certain operating threshold in the setting of timing information, and only the user is stable in a rational and calm state. Only operation can set timing information, so as to protect the life safety of users. At the same time, for children and other people who use the program-controlled equipment unintentionally, the timing information of the target program-controlled mode can be obtained only when the operations corresponding to all the sliders being slid are valid. Avoid misuse.

The program-controlled device of the present application can set timing information through a simple sliding operation. As far as the doctor using the program-controlled device is concerned, the setting efficiency is improved. At the same time, considering the patients who use the program-controlled device, first determine whether the operation is effective, and then according to The timing information is set, thus achieving people-oriented and reflecting humanized care.

Referring to FIG. 7 , in some optional embodiments, one slider being slid is used as the target slider, and the process of detecting whether the operation of sliding the target slider is valid may include steps S501 to S503 .

Step S501: Based on the operation of sliding the target slider, obtain the sliding path corresponding to the target slider, and detect whether the positions of each track point of the sliding path are all in a preset sliding area;

Step S502: when the position of at least one trajectory point of the sliding path is not in the preset sliding area, determine that the operation of sliding the target slider is invalid;

Step S503: When the positions of each track point of the sliding path are in the preset sliding area, it is determined that the operation of sliding the target slider is valid.

Therefore, whether the operation of the sliding target slider is valid is determined by detecting the positions of each track point of the sliding path, and the operation of sliding the target slider is determined to be valid only when the positions of each track point are in the preset sliding area. Then, timing information is acquired, thereby avoiding user misoperation.

Referring to FIG. 8 , in some optional embodiments, the process of detecting whether the operation of sliding the target slider is valid may include steps S601 to S604.

Step S601: When the position of each track point of the sliding path is in the preset sliding area, obtain a reference path corresponding to the sliding path based on the starting point, the ending point and the path direction of the sliding path. the path is a part of a preset circumferential path and the path direction of the reference path is determined by the path direction of the sliding path, the preset circumferential path is in the preset sliding area;

Step S602: Detecting whether the similarity between the sliding path and the reference path is not less than a preset similarity threshold;

Step S603: when the similarity is less than the preset similarity threshold, it is determined that the operation of sliding the target slider is invalid;

Step S604: When the similarity is not less than the preset similarity threshold, it is determined that the operation of sliding the target slider is valid.

In some embodiments, the shape of the predetermined sliding area may be a circular ring concentric with the predetermined circumferential path.

Therefore, the two-stage detection process is used to judge whether the sliding operation is valid, and the timing information of the target program control mode is obtained only when the sliding operation is judged to be valid. When sliding the area, it is not directly determined that the sliding operation is valid, but the second stage of detection is entered. When the detected similarity is not less than the preset similarity threshold, the sliding operation is determined to be valid, and then the timing information is obtained, and the two-stage detection The process can play the role of double insurance, preventing users from setting unreasonable timing information due to misoperation, and ensuring the safety of patients' lives.

Specifically, in the first stage, it is detected whether the position of each trajectory point of the sliding path is in the preset sliding area, and when it is detected that the position of each trajectory point of the sliding path is in the preset sliding area, it indicates that The user may have the intention to set the timing information, and then enter the second stage; in the second stage, based on the starting point, end point and path direction of the sliding path, the reference path corresponding to the sliding path is obtained, and the similarity between the sliding path and the reference path is obtained. It is detected whether the similarity is not less than the preset similarity threshold, and when the similarity is not less than the preset similarity threshold, it can be determined that the sliding operation is not a wrong operation, and the sliding operation is valid.

Obtaining the validity judgment result through the two-stage detection process is not the ultimate goal. The ultimate goal is to judge the real intention of the user's operation according to the validity judgment result, so that the set timing information conforms to the user's psychological expectation, thereby improving the user's use experience.

In some embodiments, the similarity between the sliding path and the reference path can be obtained in the following manner:

Obtaining a plurality of similarity training data, each of the similarity training data includes a sample sliding path for training, a sample reference path, and the marked similarity of the two;

Using a plurality of the similarity training data to train a preset deep learning model to obtain a similarity model;

Inputting the sliding path and the reference path into the similarity model to obtain the similarity.

Therefore, the preset deep learning model can be trained according to the similarity training data, and the similarity model can be obtained. Just input the sliding path and the reference path into the similarity model, and the corresponding similarity can be automatically generated in real time, and the degree of intelligence is relatively high. high. Through design, an appropriate amount of neuron computing nodes and a multi-layer computing hierarchy are established, and the appropriate input layer and output layer can be selected to obtain a preset deep learning model. Through the learning and tuning of the preset deep learning model, The functional relationship from input to output is established. Although the functional relationship between input and output cannot be found 100%, it can approximate the actual relationship as much as possible. The similarity model obtained by training can output the corresponding similarity in real time. And the output result has high reliability.

In some embodiments, the preset similarity threshold can be obtained in the following manner:

Obtain the third correspondence between the disease type and the similarity threshold;

Based on the disease type of the patient and the third correspondence, a similarity threshold corresponding to the patient's disease type is acquired as the preset similarity threshold.

As a result, patients with different disease types may have different hand control abilities. Compared with patients with strong hand control, Parkinson's patients with poor hand control have deviations between the sliding path and the preset circular path when sliding. It may be larger and the similarity may be lower. For patients with different disease types, different preset similarity thresholds are used, so that the program-controlled device can support patients with poor hand control to perform sliding operations, which greatly reduces the use of program-controlled devices. Difficulty in operating the device.

In a specific application, the similarity threshold corresponding to Parkinson's disease is 60%, the similarity threshold corresponding to depression is 80%, and the similarity threshold corresponding to drug addiction is 85%.

For example, the patient Zhang San is a Parkinson's patient, and Zhang San's preset similarity threshold is 60%. When the patient has more than one disease type, the lowest one of the similarity thresholds corresponding to all the disease types of the patient may be used as the preset similarity threshold of the patient, or the similarity threshold corresponding to all the disease types of the patient may be used The highest one is used as the preset similarity threshold for the patient.

Referring to FIG. 9 , in some optional embodiments, steps S701 to S703 may be used to obtain the reference path:

Step S701: Find the point closest to the starting point of the sliding path on the preset circular path as the starting point of the reference path;

Step S702: Find the point closest to the end point of the sliding path on the preset circular path as the end point of the reference path;

Step S703: Based on the path direction of the sliding path, take the path between the start point and the end point of the reference path from the preset circular path as the reference path.

Therefore, the point on the preset circular path that is closest to the starting point of the sliding path is used as the starting point of the reference path, and the point on the preset circular path that is closest to the end point of the sliding path is used as the end point of the reference path, and the preset circular path is intercepted. The path direction along the sliding path is the path from the start point to the end point of the reference path as the reference path, the reference path obtained from this is more suitable for the sliding path, and it is reasonable to obtain the corresponding timing information according to the reference path, which can truly reflect the user. Intent when setting timing information.

In some optional embodiments, the two sliders include a start slider for indicating a start moment and an end slider for indicating an end moment;

Wherein, the vector of the center of the dial pointing to the start slider is taken as the first vector, and the vector of the center of the dial pointing to the end slider is taken as the second vector, the first vector along the direction of the dial The included angle from the clockwise direction to the second vector does not exceed 180 degrees.

Therefore, the clockwise direction of the dial is selected as the extending direction from the start time to the end time, and the time period corresponding to the start time to the end time does not exceed the time period corresponding to half of the dial.

For example: it is stipulated that the time period around the dial is 24 hours (that is, the 24-hour system is adopted). When the corresponding times of the two sliders are 23:00 and 1:00 in turn, determine that the slider corresponding to 23:00 is Start slider, the slider corresponding to 1:00 is the end slider, the time period determined by this is from 23:00 of the day to 1:00 of the next day (the duration is 2 hours), not 1:00 of the day Until 23:00 of the day (the duration is 22 hours), this method is more in line with the user's operating habits.

In a specific application, the times corresponding to the positions of the two sliders are 5:00 and 15:00 in sequence, the slider corresponding to 5:00 is determined as the start slider, and the slider corresponding to 15:00 is determined as the end slider. The time period thus determined is 5:00 to 15:00 of the day (10 hours).

In this way, the sliders corresponding to the start slider and the end slider are not constant, and the specific distribution of the two sliders is determined by the user's sliding operation.

For example, the two sliders are slider c and slider d, respectively. When the time corresponding to the position of slider c is 23:00, and the time corresponding to the position of slider d is 1:00, slider c starts to slide. block, the slider d is the end slider; and when the time corresponding to the position of the slider c is 15:00, and the time corresponding to the position of the slider d is 5:00, the slider c is the end slider, and the slider d Slider for start.

Step S802: Use the touch screen to receive a synchronization operation, and in response to the synchronization operation, perform synchronization processing on the clock information of the stimulator and the clock information of the program-controlled device.

Therefore, by synchronizing the clock information of the stimulator and the clock information of the program-controlled device, it is possible to avoid deviations in the setting of timing information caused by the asynchronous clock information of the stimulator and the program-controlled device.

In a specific application, the clock information of the stimulator indicates 16:47:20, and the clock information of the program-controlled device indicates 16:40:20. The clock information of the stimulator and the clock information of the program-controlled device are processed synchronously, so that the The clock information is synchronized with the clock information of the program-controlled equipment, which is 16:40:20.

In some optional embodiments, the method may further include:

Obtain the first correspondence between the disease type and the preset duration;

determining a preset duration corresponding to the patient based on the disease type of the patient and the first correspondence;

When it is detected that the duration corresponding to the timing information of the target programming mode is greater than the preset duration corresponding to the patient, the user is prompted to re-operate.

Therefore, patients with different disease types have different durations allowed to receive stimulation, and the corresponding preset duration is determined according to the patient's disease type, so that the timing information can only be set within the range allowed by the corresponding preset duration, so as to protect the life of the patient. Safety.

In a specific application, the preset duration corresponding to Parkinson's disease is 8 hours, the preset duration corresponding to depression is 3 hours, and the preset duration corresponding to drug addiction is 7 hours.

For example, the patient Zhang San is a Parkinson's patient, and the preset duration of Zhang San is 8 hours. When the patient has more than one disease type, the shortest one of the preset durations corresponding to all the disease types of the patient may be used as the preset duration of the patient.

In some optional embodiments, the method may further include:

obtaining a second correspondence between disease types and preset tissues;

Based on the disease type of the patient and the second correspondence, a preset tissue corresponding to the disease type of the patient is acquired as the target tissue corresponding to the patient.

The predetermined tissue may be brain tissue, and the predetermined tissue may include one or more of the subthalamic nucleus, the medial globus pallidus, the ventromedial nucleus of the thalamus, the left internal capsule forelimb, the left nucleus accumbens, the right internal capsule forelimb, and the right nucleus accumbens. indivual. In some specific applications, the predetermined tissue may be a brain tissue formed by a plurality of brain cells. In other specific applications, the predetermined tissue can also be a single brain cell.

Therefore, patients with different disease types receive different body tissues to be stimulated, and the corresponding target tissue is determined according to the patient's disease type, so as to apply electrical stimulation to the patient's target tissue in a targeted manner to meet the needs of practical applications.

The program-controlled device of the present application does not limit the applicable disease types, and the disease types include but are not limited to: spastic disease (eg, epilepsy), pain, migraine, mental illness (eg, major depressive disorder (MDD)), bipolar disorder , anxiety disorders, post-traumatic stress disorder, major depressive disorder, obsessive-compulsive disorder (OCD), behavioral disorders, mood disorders, memory disorders, mental state disorders, mobility disorders (eg, tremor or Parkinson's disease), Huntington's disease, Alzheimer's disease Zheimer's disease, drug addiction or other neurological or psychiatric diseases and impairments. When program-controlled equipment is used to treat drug addicts, it can help drug addicts detox and improve their well-being and quality of life.

In some optional embodiments, the patient's disease type includes one or more of epilepsy, tremor, Parkinson's disease, depression, obsessive-compulsive disorder, Alzheimer's disease, and drug addiction.

Therefore, the stimulators in patients with different disease types can be controlled by using the program-controlled equipment, and the scope of application is wide.
