However, the existing related technologies still have some shortcomings, such as the inability to comprehensively collect and utilize effective information to provide doctors with more precise assistance. Therefore, the existing technologies need to be improved. [Summary of the Invention]

Detailed Implementation Methods

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0029] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0030] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] Please see Figure 1 and Figure 2 This invention relates to the field of medical device technology, specifically to a spinal grinding control method and system based on a brushless motor as a power component.

[0032] The spinal grinding control method of the present invention includes:

[0033] Parameter storage and operation. Various parameters related to spinal grinding are pre-stored in the system, including but not limited to reference values ​​for grinding depth and speed for different spinal locations. During the procedure, the system automatically calls upon the corresponding stored parameters to control the operation of the grinding device based on the selected surgical site and operating mode, ensuring that the basic parameter settings of the grinding process meet the surgical requirements.

[0034] Information Collection and Evaluation. While the grinding device is running, real-time data such as its rotational speed and current are collected. This data is analyzed and processed, and combined with pre-defined algorithms and models, to evaluate the bone condition at the surgical site and the grinding process. For example, by analyzing trends in rotational speed and current, it's possible to determine if abnormal resistance was encountered during grinding, or if bone hardness changed, thus promptly identifying potential problems and alerting the doctor.

[0035] Display and Decision Support: Real-time data such as rotational speed and current are displayed on the touchscreen, allowing doctors to intuitively understand the working status of the grinding device. Simultaneously, the difference between the set parameters and actual parameters is calculated. Based on this difference and other collected information, effective information about the surgical site, such as remaining grinding depth and potential surgical risks, is further predicted, providing doctors with comprehensive decision support and helping them perform surgical procedures more accurately.

[0036] Specifically, the spinal grinding control method of the present invention includes the following steps:

[0037] Step S1: Read the preset parameters stored in the storage medium. The preset parameters include parameters related to spine grinding, such as preset grinding speed and preset grinding pressure.

[0038] Step S2: Start the grinding device according to the preset parameters. During the grinding process, the sensor collects effective information such as the rotation speed, current and pressure applied to the surgical site in real time.

[0039] Step S3: Evaluate the surgical site based on the collected valid information. The evaluation includes determining the contact state between the grinding device and the spinal tissue based on the rotation speed and current information, and determining whether the grinding force on the spinal tissue is appropriate based on the pressure information.

[0040] Step S4: Display the real-time speed information, current information, and evaluation results on the touch screen, and calculate the difference between the set parameters and the actual parameters, such as the difference between the preset speed and the actual speed, the difference between the preset pressure and the actual pressure, etc.

[0041] Step S5: Based on the difference between the set parameters and the actual parameters, as well as the collected effective information, the pre-established prediction model is used to predict the subsequent trend of effective information changes at the surgical site, such as predicting the tissue reaction and grinding depth changes at the surgical site when the current grinding operation continues. The prediction results are then displayed on the touch screen to provide doctors with auxiliary decision-making information.

[0042] Specifically, in the spinal grinding control method of the present invention:

[0043] First, the system reads preset parameters from the storage medium upon startup. These preset parameters are set based on extensive clinical trial data and the experience of medical experts, and are adaptable to the needs of different types of spinal surgeries. For example, appropriate grinding speed and pressure ranges are preset for different spinal lesion sites and surgical stages.

[0044] During the grinding process, the speed sensor, current sensor, and pressure sensor in the information acquisition module collect relevant information in real time. The speed information reflects the rotational speed of the grinding tool, the current information is related to the resistance experienced by the grinding tool and can indirectly reflect the hardness of the surgical site and the difficulty of grinding, and the pressure information directly reflects the magnitude of the force applied to the surgical site.

[0045] The assessment module uses this collected information to evaluate the surgical site. For example, if the rotation speed suddenly decreases and the current increases, it may indicate that the grinding tool has encountered hard spinal tissue or has become stuck, and the assessment module will issue a corresponding warning message.

[0046] The display module intuitively shows real-time information such as rotational speed and current, as well as evaluation results, on the touchscreen, allowing doctors to view them at any time. Simultaneously, it calculates the difference between the set parameters and the actual parameters; for example, if the preset rotational speed is 30,000 rpm and the actual speed is 29,500 rpm, the difference is 500 rpm.

[0047] The prediction module uses a pre-established prediction model based on machine learning algorithms or mathematical models, combining the difference with the collected effective information to predict effective information about the surgical site. For example, if the current rotation speed difference gradually increases and the current also rises, the prediction model may predict that continuing grinding will cause the temperature of the surgical site to rise too quickly, posing a risk of damaging surrounding nerve tissue. This prediction result is displayed on the touch screen, allowing the doctor to adjust the grinding operation parameters or take appropriate protective measures.

[0048] The various modules in the spinal grinding control device of this invention work together to achieve precise control and effective information feedback for spinal grinding surgery. The storage medium stores the relevant programs and data, ensuring the stable operation of the entire system and reliable data storage.

[0049] The spinal grinding control method, device, and storage medium of the present invention can improve the precision and safety of spinal grinding surgery, provide doctors with more comprehensive and accurate surgical assistance information, and help improve the overall quality and effect of spinal surgery.

[0050] The spinal grinding control system of the present invention includes:

[0052] Parameter storage module: This module stores various parameters related to spinal grinding. It can use non-volatile memory, such as flash memory, to ensure that the parameters are not lost after power failure. This module is scalable, allowing for easy updating and expansion of the stored parameters based on different surgical needs and clinical research findings.

[0053] Information Acquisition Module: Equipped with high-precision sensors, this module collects valuable information during spinal grinding, including the rotational speed, current, and pressure at the surgical site. The sensors chosen must meet requirements for high precision, high reliability, and real-time performance; for example, Hall effect sensors are used to measure current, and photoelectric encoders to measure rotational speed. The acquired information is conditioned and converted from analog to digital before being transmitted to the control module for processing. The sensors include a rotational speed acquisition module, a current acquisition module, and a pressure acquisition module. The rotational speed acquisition module is connected to the motor, the current acquisition module is connected to the motor drive module, and the pressure acquisition module is located at the surgical site.

[0054] Control Module: As the core of the system, it coordinates the work of all modules. It controls the operation of the grinding device based on parameters stored in the parameter storage module and analyzes and processes data from the information acquisition module. The control module employs an advanced microprocessor or digital signal processor, possessing powerful computing capabilities and a fast response speed, enabling it to run complex control algorithms and evaluation models in real time. The speed acquisition module, current acquisition module, and pressure acquisition module are each connected to the processor.

[0055] Display Module: Utilizing a touchscreen as the display device, this module features an intuitive and user-friendly interface. The touchscreen clearly displays real-time speed, current, and other information, as well as calculated differences and predicted values. Doctors can use the touchscreen to set parameters, select operating modes, and perform other operations, enabling human-computer interaction. The display module shows real-time speed and current information, along with evaluation results, on the touchscreen, and also displays the difference between the set parameters and the actual parameters.

[0056] Storage medium: Used to store computer instructions for implementing the above-described spinal grinding control method. When executed by a processor, these computer instructions implement the steps of the spinal grinding control method. The storage medium can be any medium capable of storing program code, such as read-only memory (ROM), random access memory (RAM), disk storage, or optical storage. When the control system reads and executes the program in the storage medium, it can implement each step of the spinal grinding control method, thereby enabling the computer system to possess intelligent control and auxiliary functions for spinal grinding. The memory is connected to the processor.

[0057] The spinal grinding control system of the present invention further includes:

[0058] Parameter reading module: used to read preset parameters stored in the storage medium;

[0059] Assessment module: Used to assess the surgical site based on the collected valid information;

[0060] Prediction module: Based on the difference between the set parameters and the actual parameters, as well as the collected valid information, it uses a pre-established prediction model to predict the subsequent changes in valid information at the surgical site and displays the prediction results on the touch screen.

[0061] Compared with existing technologies, the spinal grinding control method and system of the present invention improves the standardization and normalization of spinal grinding surgery by automatically recalling and running stored parameters, reducing parameter setting errors caused by human factors, thereby improving the safety and success rate of the surgery. Real-time acquisition and analysis of information such as rotation speed and current can more accurately assess the condition of the surgical site, promptly detect abnormalities during surgery, provide doctors with more timely and accurate information support, help doctors make more reasonable decisions, and reduce surgical risks.

At the same time, the human-computer interaction function allows doctors to adjust parameters and operating modes more flexibly, improving the controllability and convenience of the surgery.
