Description

Technical Field

[0001] The present invention relates to the technical field of medical video recording systems, and in particular to a video recording system of a wearable device for spinal surgery. Background Art

[0002] The wearable device recording system for spinal surgery is a medical device designed specifically for spinal surgery that integrates recording and wearable features. Through its wearable design, the system tightly fits a high-definition camera or other image acquisition equipment to a specific part of the doctor or patient, so that the surgical screen can be recorded and transmitted in real time during the operation, providing intuitive and clear image data for surgical operations, teaching training, postoperative evaluation, etc. However, when using the wearable device recording system for spinal surgery, it usually only has basic recording functions to record the surgical process for postoperative review, teaching or legal evidence preservation. It lacks automatic calibration and positioning functions and cannot provide real-time precise location information of surgical instruments or implants. Summary of the invention

[0003] In order to overcome the problem that when using wearable device recording systems for spinal surgery, they usually only have basic recording functions to record the surgical process for postoperative review, teaching or legal evidence preservation, lack automatic calibration and positioning functions, and cannot provide precise position information of surgical instruments or implants in real time.

[0004] The technical solution of the present invention is: a video recording system of a wearable device for spinal surgery, comprising:

[0005] Data acquisition module: used for real-time acquisition of video images and dynamic data during spinal surgery;

[0006] Data transmission module: used to transmit the dynamic data collected by the data acquisition module;

[0007] Data preprocessing module: used to preprocess the dynamic data transmitted by the data transmission module;

[0008] Calibration and positioning module: used to automatically calibrate and track the position and posture of the spine in real time during surgery;

[0009] Data storage module: used to store and back up various data generated when the system is running;

[0010] Power management module: used to provide stable power supply for the entire system;

[0011] Interaction module: used to provide a user interaction interface to facilitate users to operate the system.

[0012] Preferably, the data acquisition module includes multiple groups of high-precision cameras and accelerometers. The high-precision cameras are used to collect video images of the surgical process in real time and high definition. The cameras need to have wide-angle and anti-shake functions to ensure that the captured images are clear and stable and cover key parts of the surgical area. The accelerometers are used to capture the doctor's body movements during surgery.

[0013] Preferably, the data transmission module includes an Ethernet communication interface, a WIFI communication interface, a 485 communication interface and a 232 communication interface. The collected data is transmitted to the data preprocessing module through the built-in communication interface of the data acquisition module, so as to realize the remote transmission and real-time sharing of data, and provide data support for the monitoring, analysis and optimization of the production process.

[0014] Preferably, the data preprocessing module is used to fill in the missing data collected during the operation to ensure the integrity of the data. Interference data may be generated during the operation due to equipment failure or sensor error. The data preprocessing module will use smoothing technology to reduce the impact of these interference data on subsequent analysis.

[0015] Preferably, the calibration and positioning module includes multiple groups of gyroscopes and has built-in intelligent calibration algorithms and positioning technology, which can automatically calibrate and track the position and posture of the spine in real time during the operation. This helps to ensure that the video system is accurately synchronized with the patient's spinal position, providing the doctor with an accurate surgical field of view and reference. The gyroscope collects the doctor's dynamic data and tracks the spinal position and posture, and calibrates and positions the spine and the doctor's surgical position in real time.

[0016] Preferably, when the calibration and positioning module is working, the following steps are included:

[0017] S11: Ensure that the wearable device, video recording system, calibration tool and all related accessories are intact and fully charged;

[0018] S12: aligning the collected image data with the spatial coordinates in the wearable device recording system;

[0020] S14: Evaluate whether the accuracy of the initial calibration meets the surgical requirements. If not, further point cloud registration or other calibration steps are required.

[0021] S15: During the operation, dynamic calibration is required to ensure the continuous and accurate positioning of the device according to the progress and needs of the operation;

[0022] S16: After the calibration is completed, the video recording system starts to display the position of the surgical instrument and the condition of the surrounding tissue in real time;

[0023] S17: The video recording system starts to record the surgical process, including the movement of surgical instruments and image changes in the surgical area, for postoperative analysis and teaching purposes.

[0024] Preferably, the calibration and positioning module can ensure the accuracy of the equipment position during the operation. Because the spinal structure is complex, the operation requires extremely high precision. Through real-time calibration and positioning, the doctor can more accurately judge the position and depth of the surgical instruments and reduce surgical errors. The calibration and positioning module can provide a more intuitive and three-dimensional surgical field of view, helping doctors better understand the spinal structure and thus formulate a more accurate surgical plan.

[0025] Preferably, the data storage module includes an information resource management submodule and a cloud storage terminal, which integrates the surgical information collected by the data acquisition module and the calibration results analyzed by the calibration and positioning module, manages and stores the integrated data, and stores and backs up the surgical information collected by the data acquisition module and the calibration results analyzed by the calibration and positioning module to the cloud.

[0026] Preferably, when the data storage module backs up and stores data, the following method is included:

[0027] A21: Create a master document based on the corresponding date on the cloud platform;

[0028] A22: Create classification sub-documents in the main document according to the classification information;

[0029] A23: compress and encrypt the surgical information collected by the data acquisition module and the calibration results analyzed by the calibration positioning module for backup;

[0030] A24: The surgical information collected by the data acquisition module and the calibration results of the calibration positioning module are analyzed and placed into a sub-document.

[0031] Preferably, the data storage module facilitates permanent storage of various data required by the system, and can effectively back up the surgical data information collected by the data acquisition module and the analysis results of the data analysis module. The data storage module can effectively improve the response speed and processing efficiency of the system.

[0032] Preferably, the power management module is used to provide a stable power supply for the entire system, including a built-in battery pack, a charging port and a power management chip. The power management module needs to ensure that the device continues to be powered during the operation while avoiding safety issues such as overheating and overcharging.

[0033] Preferably, the interactive module is used to provide a user interactive interface, allowing doctors or operators to control various functions of the video recording system, including starting or stopping recording, adjusting the camera angle, and viewing real-time video and positioning information.

[0034] Beneficial effects of the present invention:

Compared with traditional wearable device video recording systems for spinal surgery, which usually only have basic video recording functions to record the surgical process for postoperative review, teaching or legal evidence preservation, lack automatic calibration and positioning functions, and cannot provide accurate position information of surgical instruments or implants in real time, this wearable device video recording system for spinal surgery can automatically calibrate the video recording system to ensure the accuracy and stability of the video recording, reduce errors caused by device offset or movement, and at the same time, by providing real-time and accurate surgical instrument and implant position information, help surgeons complete surgical operations more accurately and reduce the occurrence of complications;
