[0002] With the progress of social population aging and changes in modern work and lifestyle, the incidence of spinal degenerative diseases is on the rise and is becoming younger and younger. According to the report of the National Spine Society (NASS), the total number of spinal surgeries has continued to rise in the past 10 years, especially the proportion of surgeries in elderly and young patients has gradually increased. Surgery is the ultimate treatment for severe spinal degeneration. According to statistics, the number of spinal degenerative lesions surgeries increased by more than 70% between 2010 and 2020. Dural sac tear and nerve root injury are common complications in spinal surgery. According to literature reports, the incidence of dural sac tear in spinal surgery is about 1%-10%, and the specific proportion depends on the complexity of the operation and the individual situation of the patient. How to reduce the incidence of dural injury tear during pedicle screw implantation in spinal surgery has become a focus of attention. At present, the main methods of determining whether the pedicle screw passes through the medial cortex of the pedicle are visual, tactile, and intraoperative X-ray positioning, but inaccurate positioning, cortical penetration, traction, and tearing of the dura mater may still occur. While prolonging the operation time, it also increases the risk of perioperative complications in patients. With the gradual application of artificial intelligence in surgery, how to quickly and accurately identify the penetration of the medial pedicle cortex by the screw during spinal surgery, identify the risk of damage to the dura mater during the screw placement and drilling process, and prevent dura mater and nerve damage have become urgent issues to be solved. Dura mater rupture is usually caused by instrument manipulation or removal of vertebral plates during surgery, which may cause cerebrospinal fluid leakage, postoperative headaches or intracranial infections. Protection of the dura mater during screw placement is an essential step in surgery. Summary of the invention

[0008] Furthermore, the outer surface of the soft film body is covered with a high molecular polymer coating to ensure good biocompatibility.

[0009] Furthermore, the sensor is a vibration sensor for detecting vibration changes of the film body.

[0010] According to another aspect of the present application, a signal monitoring device is provided, comprising the above-mentioned spinal membrane protection film for spinal surgery, as well as a signal feedback device and a power supply device.

[0034] Reference below Figures 1 to 6 , the present invention is further described:

[0035] A spinal membrane protection soft sheet for use during surgery, comprising:

[0036] The soft film body 1 is made of piezoelectric material, is in the shape of a thin sheet as a whole, has a rounded rectangular cross section, and has a sensor 2 arranged inside.

[0037] This property of piezoelectric material enables the film to monitor the touch during surgery in real time, providing doctors with instant feedback. In addition, the thin sheet and rounded rectangular cross-section design make it easy for the film to fit the spinal structure, improving the accuracy and safety of the surgery.

[0038] During the operation, the surgeon uses a nerve stripper and a nerve hook to pull the dura mater sac under direct vision and slide the pedicle to determine whether the screw has penetrated the medial pedicle bone cortex and reduce the related adverse effects. At present, conductive materials that are sensitive to stress, strain or structural changes will affect the resistivity, shape and size of the material when they are deformed, thereby causing resistance changes. By using a microvoltmeter to record and detect small changes caused by material deformation, setting a change rate threshold, amplifying and processing the signal, a sound alarm or a visual alarm is achieved. This device uses relevant piezoelectric materials to transmit a warning signal through the deformation of the material when the pedicle screw penetrates the bone cortex during the process of pedicle screw placement, and also plays a certain physical protection role.

[0039] Piezoelectric materials are widely used in the fields of sensors, actuators, energy harvesting equipment and medical devices. This patent combines the "Fast Fourier Transform (FFT)", "Wavelet Packet Transform (WPT)", "Electrical Impedance Tomography (EIT)" technology with piezoelectric materials to identify the penetration of the medial pedicle cortex by collecting signals, data processing, and real-time monitoring. A piezoelectric material film is placed between the dura mater and the pedicle to directly protect the dura mater through physical isolation, reducing surgical trauma. Compared with traditional surgical methods, this device selects piezoelectric materials with good biocompatibility to achieve higher recognition accuracy and safety in determining whether the pedicle screw has penetrated the medial bone cortex during insertion, and is worthy of clinical promotion and application.

[0040] In a preferred embodiment, the film body 1 is made of plastic material and can be bent into a variety of curves according to the needs of use to adapt to the spinal morphology of different patients and better adapt to the physiological curvature of the spine. This design not only improves the application range of the film, but also makes the film more stable during the operation, not easy to fall off or shift, improves the applicability and fit of the film, thereby further enhancing the safety of the operation and making the protection effect more significant.

[0041] In an optional embodiment, a variety of sensors such as temperature, humidity, and chemical sensing are integrated into the film body 1 to achieve comprehensive monitoring of the surgical environment and provide richer information support for the surgical process.

[0042] In an optional embodiment, the outer surface of the film body 1 is covered with a polymer coating to ensure good biocompatibility. The polymer coating has good biocompatibility, which means that it has good compatibility with human tissue and will not cause problems such as rejection or infection. In addition, the coating can also provide additional lubricity and wear resistance, making the film easier to place and move during surgery, while reducing the risk of damage to surrounding tissues. The composition and process of the polymer coating can also be adjusted to improve the lubricity of the coating, reduce friction and resistance during surgery, and reduce the risk of damage to surrounding tissues.

[0043] In this embodiment, due to the piezoelectric properties of the film body 1, the pressure change acting on the film body 1 can be converted into an electrical impedance change. By monitoring the change of the electrical impedance signal of the film body 1, the signal is transmitted to the signal feedback device (3), and the signal feedback device (3) analyzes and processes the received information. In spinal surgery, when the pedicle screw or other surgical instruments touch the spinal membrane protection film, the film will be subjected to a certain pressure, thereby triggering the pressure sensor to send a signal. The doctor can adjust the surgical operation in time according to these signals to avoid damage to the spinal membrane.

[0044] Optionally, sensor 2 may also adopt a wireless pressure sensor to achieve wireless data transmission and remote monitoring, thereby improving the convenience and safety of the operation.

[0045] In this embodiment, the sensor 2 can also be a vibration sensor for detecting the vibration changes of the film body 1. The vibration sensor can monitor the vibration changes of the film when it is subjected to external force, and convert these changes into electrical signals for transmission and processing. In spinal surgery, when the surgical instrument comes into contact with the spinal membrane protection film, the film body 1 may produce tiny vibrations. The vibration sensor can capture these vibration signals, convert the vibration signals into electrical signals, and remind the doctor to pay attention to the safety of the surgical operation, adjust the position and strength of the surgical instrument, and help avoid unnecessary damage to the spinal membrane.

[0046] Preferably, a wide-band vibration sensor is used to monitor vibration signals of different frequencies, thereby improving the accuracy and comprehensiveness of monitoring.

[0047] Optionally, the signal feedback device 3 may be combined with artificial intelligence and machine learning technologies to automatically identify abnormal vibration signals during surgery and issue an early warning through an intelligent recognition algorithm.

[0048] The pressure sensor is used to detect the pressure change on the film body 1, while the vibration sensor is used to detect the vibration change of the film body 1. Both sensors can effectively sense the potential threat to the spinal membrane during the pedicle screw placement process.

[0049] According to another aspect of the present application, a signal monitoring device is provided, comprising the above-mentioned spinal membrane protection film for spinal surgery, as well as a signal feedback device 3 and a power supply device 4.

[0050] The main function of the signal monitoring device of the present application is to receive and process the electrical signals sent by the sensor 2 in the spinal membrane protection film, and then present this information to the doctor in a visual manner. In this way, the doctor can adjust the surgical operation according to the real-time feedback signal to ensure the safety and accuracy of the operation.

[0051] The introduction of the signal monitoring device connects the spinal membrane protection film with the signal feedback device 3 and the power supply device 4 to form a complete monitoring system. This design enables the doctor to understand the status of the film in real time during the operation and make adjustments as needed. At the same time, the signal monitoring device also provides a variety of signal processing methods, such as fast Fourier transform, wavelet packet transform, etc., which further improves the accuracy and safety of the operation.

[0052] The film body 1 is connected with the signal feedback device 3 and the power supply device 4 to form a loop. The loop is the basis of signal transmission and processing. Only when the loop is unobstructed can the electrical signal sent by the sensor 2 be accurately received and processed. In this embodiment, the film body 1, as the source of the signal, is connected with the signal feedback device and the power supply device through a wire to form a complete loop. In this way, when the film is subjected to an external force, the electrical signal generated by the sensor can be transmitted to the signal feedback device through the loop for processing.

[0053] Optionally, batteries are provided inside the film body 1 and the signal feedback device 3 for independent power supply, and wireless connection technology, such as Bluetooth, Wi-Fi, etc., is used to realize wireless signal transmission between the film body 1 and the signal feedback device 3, thereby abandoning traditional cable connection and reducing cable interference and safety hazards during surgery.

[0054] The signal feedback device 3 is electrically connected to the sensor 2 inside the film body 1 to react to the change in the electrical impedance signal of the film body 1. This connection is a key link in signal transmission. Only by ensuring that the electrical connection between the sensor and the signal feedback device is stable and reliable can the accurate transmission and processing of the signal be ensured. In the signal monitoring device, the sensor 2 is connected to the signal feedback device 3 through a wire to form a channel for electrical signal transmission. When the sensor 2 detects a corresponding change, it generates an electrical signal and transmits it through this channel to the signal feedback device 3 for processing and analysis.

[0055] Preferably, the introduction of adaptive filtering technology can automatically identify and filter noise signals during the operation, improve the signal-to-noise ratio and reliability of the data, and make the signal feedback more accurate.

[0056] In a preferred embodiment, a signal processing module is disposed inside the signal feedback device 3 .

[0057] In the present embodiment, the signal processing module utilizes the method of fast Fourier transform, wavelet packet transform, and electrical impedance imaging to feedback the change of the electrical impedance signal of the film body 1. The signal processing module is the core part of the signal feedback device, which is responsible for receiving the original electrical signal sent by the sensor 2, and processing and analyzing it to extract useful information. In spinal surgery, the signal processing module can utilize the methods such as fast Fourier transform, wavelet packet transform, and electrical impedance imaging to process and analyze the electrical signal sent by the sensor, thereby realizing real-time monitoring and early warning of the protective state of the spinal membrane during the operation. The two signal processing technologies combined with the alarm can ensure that the doctor can quickly and accurately identify the screw penetrating the medial pedicle cortex during the operation. And it plays a protective role on the dura mater. In this way, the doctor can adjust the surgical operation according to the information provided by the signal processing module to ensure the safety and accuracy of the operation.

[0058] The use of signal processing methods such as fast Fourier transform, wavelet packet transform, and electrical impedance imaging can more accurately reflect the state changes of the film during surgery and provide doctors with more detailed feedback. At the same time, the application of these methods also improves the level of intelligence of surgery, making the surgical process more efficient and safer.

[0059] The method of using the signal monitoring device of the present application is as follows:

[0060] S1, the spinous process and lamina that need to be removed are removed;

[0061] S2, the spinal membrane protective soft sheet is placed between the pedicles and dura mater sac and covers the surface of the dura mater sac;

[0062] S3, insert the pedicle screw at the corresponding position around the pedicle. If the spinal membrane protection film is touched during the insertion process, the sensor 2 inside the spinal membrane protection film will send out an electrical signal to provide a signal feedback for the touch;

[0063] S4, adjusting the pedicle screw insertion position and insertion force at any time according to the signal sent by the signal feedback device;

[0064] S5, after the pedicle screw placement process is completed, the spinal membrane protective film is removed and the wound is sutured.

[0065] During the placement process, doctors need to adjust the surgical operation according to the real-time feedback provided by the signal monitoring device to ensure the safety and accuracy of the operation. For example, during the placement of pedicle screws, if the signal monitoring device sends a warning signal, the doctor needs to stop the operation immediately and check the position and strength of the pedicle screws to avoid damage to the spinal membrane. In this way, doctors can complete spinal surgery more safely and accurately.

[0066] In an optional embodiment, a wireless communication module (such as Bluetooth, Wi-Fi) can be integrated into the signal feedback device 3 to achieve remote communication between the signal monitoring device and monitoring equipment outside the operating room or the doctor's handheld device, so that the doctor can view and analyze data at any time during the operation.

[0067] In practical applications, special spinal membrane protection films and signal monitoring devices can be developed for complex surgeries such as scoliosis and spinal tumors to provide more sophisticated surgical monitoring and early warning functions and reduce surgical risks.

[0068] The surgical procedure is as follows:

[0069] After satisfactory anesthesia, the patient takes the prone position, properly padded, iodine disinfection of the lumbar surgical area, spread the towel, take the posterior lumbar midline incision, cut the skin and subcutaneous tissue longitudinally along the long axis of the body, and cut the deep fascia of the waist layer by layer. Expose the 3-5 lumbar spinous processes layer by layer along the midline, peel off the paravertebral muscles to the lamina, place automatic retractors to open, identify the lumbar 3-5 bilateral nailing points, after accurate positioning, make holes at the corresponding nailing points, place positioning pins, after accurate positioning, use forceps to bite off the 3-5 lumbar spinous processes, completely expose the 3-5 lumbar lamina, articular processes and bilateral transverse processes, use high-speed grinding drill to grind and cooperate with bone rongeurs to bite off the 3-5 bilateral articular processes of the lumbar 3, and then use high-speed grinding drill to grind and thin the 3-5 lumbar lamina, use corresponding types of bone rongeurs to bite off the 3-5 lumbar lamina, and use nerve stripping tools. The yellow ligament at L3-5 was lifted and removed under direct vision. The dura mater sac was seen to bulge, and hemostasis was fully achieved. The catheter was explored to loosen the adhesion of the dura mater sac and nerve root adhesion. The dura mater sac bulged well. After sufficient hemostasis, the screw placement points on both sides of L4-5 were identified, the positioning needle was removed, the thread was tapped, the four walls were explored, the depth was measured, and the screws of appropriate specifications were selected (a protective film was placed between the dura mater sac and the pedicle). During the pedicle screw placement, attention was paid to whether the protective film had any signal prompts, and the signal changes during the pedicle screw placement were recorded. After the screw was placed, the fluoroscopic view showed that the position, angle and length of each pedicle screw were appropriate, and the titanium rod was connected. The intervertebral space was expanded to expose the L3 / 4 and L4 / 5 intervertebral discs. The L3 / 4 and L4 / 5 intervertebral discs were removed with the corresponding type of curettes, and the cartilage end plates were scraped off. The appropriate type of intervertebral fusion device was selected by trial model, and bone particles were implanted in front of the intervertebral space and compacted. Then, an intervertebral fusion device filled with autologous bone was inserted into the L3 / 4 and L4 / 5 intervertebral space. After the insertion position was satisfactory, the intervertebral space was held tightly and bone was grafted around the intervertebral fusion device. The position and length of the pedicle screws and the position of the fusion device were satisfactory, and the tail caps were tightened, the transverse connection was installed, and the pedicle screws were repeatedly rinsed and hemostasis was stopped. The instruments were counted correctly, and a drainage tube was placed in the wound. The wound was sutured layer by layer, and the operation was completed.

[0070] During the above-mentioned surgical procedure, identifying the screw placement points on both sides of L4-5 is a key step in the operation. The screw placement points need to be accurately determined to ensure the accurate placement of subsequent pedicle screws.

[0071] In addition to the above functions, when performing spinal surgery, before using the drill to grind the vertebral plate, the soft film body 1 can be placed on one side of the vertebral plate, and then the drill is used to grind the vertebral plate. During the grinding process, the vibration sensor built into the soft film body 1 is used to detect the vibration generated when the drill contacts the vertebral plate in real time. When the drill uses different forces to grind the vertebral plate or grinds different positions of the vertebral plate, the vibration emitted is also different. Since the change in vibration will also cause the change in sound synchronously, the vibration sensor can also indirectly detect the change in sound. Through this feature, the signal feedback device 3 can use the change in vibration and sound to determine the degree of grinding of the vertebral plate by the drill and whether it touches other tissues such as nerves, and provide feedback in real time. During this process, medical staff can use the information fed back by the signal feedback device 3 to identify in real time whether the operation is in a dangerous state at this time, so as to adjust the parameters such as the grinding angle and force in time. In this way, the patient's intraoperative safety can be guaranteed to a greater extent. Medical staff will make detailed plans and preparations before the operation, including determining the surgical path, selecting appropriate grinding tools, etc., to increase the safety and accuracy of the operation and improve the success rate of the operation.

[0072] The surgical procedure is complex and delicate, requiring surgeons to have superb surgical skills and rich clinical experience. Through precise screw placement, laminectomy, yellow ligament resection, dural sac exploration and intervertebral fusion, the purpose of treating spinal diseases is achieved. At the same time, every step of the surgical process needs to strictly follow the principles of aseptic operation and surgical safety to ensure the safety of the patient and the success of the operation.

[0073] Based on the solution in this application, the following artificial intelligence technologies can also be introduced to assist medical staff in performing surgery better:

[0074] Intelligent signal processing algorithm: The use of artificial intelligence algorithms to intelligently process and analyze the signals collected by the signal monitoring device can more accurately identify the state changes of the spinal membrane protection film during surgery. For example, through the deep learning algorithm to extract and classify the features of the signal, the contact of the surgical instrument with the spinal membrane can be monitored in real time and the potential risk of injury can be predicted.

[0075] Surgical navigation and planning: Using artificial intelligence technology for surgical navigation and planning can further improve the accuracy of surgery. By combining the patient's preoperative imaging data and real-time data during surgery, artificial intelligence can generate three-dimensional surgical navigation images to help doctors more accurately locate the surgical site and plan the surgical path.

[0076] Intelligent decision-making support: AI can also provide doctors with intelligent decision-making support. For example, based on real-time data during surgery and individual differences of patients, AI can predict surgical risks and the probability of complications, and provide doctors with personalized surgical recommendations.

[0077] Rehabilitation plan formulation: Combining the patient's postoperative recovery and individual differences, AI can formulate a personalized rehabilitation plan. By monitoring the patient's rehabilitation progress and feedback data, AI can adjust the rehabilitation plan in real time to ensure that the patient obtains the best rehabilitation effect.

[0078] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0079] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
