[0057] According to some embodiments of the invention, a system is provided that combines robotic arm assistance with augmented reality (AR) navigation in surgery (e.g., orthopedic surgery). This system can provide a fusion of accuracy, visualization, and data-driven insights. The robotic arm can improve accuracy and / or controllability, thereby reducing human error caused by factors such as hand tremors. Furthermore, AR navigation complements this. Specifically, AR navigation can provide a real-time three-dimensional (3D) visualization of the surgical site to enhance the surgeon's understanding of the relevant anatomy and pathology. The combination of these technologies can provide highly personalized surgical plans, allowing preoperative planning based on the specific needs of each patient.

[0058] The synergy between robotic arm assistance and AR navigation can streamline the surgical procedure. For example, when the robotic arm performs precise movements, AR can display key data directly in the surgeon's field of vision, allowing for real-time adjustments and potentially leading to better surgical outcomes. In some embodiments, this combined approach can reduce radiation exposure because AR navigation can replace the need for fluoroscopy.

[0059] Furthermore, in some embodiments, the system can be used for education. For example, the system can serve as a training tool for medical students and junior surgeons, providing detailed, interactive, and highly accurate demonstrations of surgical procedures. Surgeon fatigue is a problem during long and complex surgeries, and the robotic arm can handle some physically demanding tasks, thereby reducing surgeon fatigue.

[0060] The combination of these technologies can open new avenues for data collection and postoperative analysis, which may be of significant value for future research and quality control. In addition, the precision provided by the robotic arm and AR navigation can reduce the invasiveness of the surgery, thus helping patients recover faster.

[0061] This interdisciplinary collaborative approach may foster closer collaboration among engineers, computer scientists, and medical professionals, thereby driving further innovation in surgical fields, such as orthopedic surgery. While this technology is still in its early stages and requires rigorous clinical trials to fully validate its advantages, combining robotic arm assistance with AR navigation offers several potential benefits.

[0062] Some embodiments of the present invention provide a robot-assisted AR-navigated orthopedic surgical system. This system is expected to...This system can be used in various practical applications and may help improve patient outcomes, increase surgical precision, and / or enhance medical training.

[0063] The system can be configured to improve surgical precision, reduce trauma, and / or improve overall patient outcomes. By combining robot-assisted technology and AR navigation, the system allows surgeons to accurately navigate complex anatomical structures, thereby reducing surgical errors. This precise positioning can reduce or minimize damage to surrounding tissues, thereby alleviating postoperative pain and accelerating patient recovery. In addition, the AR component can provide a real-time visualization of 3D anatomical structures, thereby helping surgeons make informed and timely decisions during surgery. The system can also be used as an educational tool, enabling medical professionals to improve or refine their skills in a simulated environment. In some embodiments, the system can reduce the overall duration and associated costs of surgical procedures through its navigation and visualization capabilities. In some embodiments, the system can be designed to collect and analyze intraoperative data, which can be used to enhance postoperative monitoring, thereby helping to improve long-term patient outcomes.

[0064] For example, the system can serve as a multi-faceted tool that has the potential to transform multiple aspects of orthopedic surgery, such as from spinal fusion and joint replacement to more complex fracture repair and arthroscopic surgery. This system can provide real-time 3D visualization and precise instrument navigation, thereby enhancing surgeons' ability to accurately perform complex surgeries such as limb lengthening, tumor resection, and correction of congenital malformations. In emergency trauma situations, the system can be rapidly deployed to assist in stabilizing fractures and dislocations, thereby ensuring optimal alignment and fixation.

[0065] For example, the system can serve as a valuable educational and postoperative monitoring tool. It can also serve as a training tool, providing a simulated environment that allows medical students and junior surgeons to practice complex surgeries. Furthermore, the system can be designed to collect and analyze surgical data, providing insights into the effectiveness of surgical interventions and assisting in future treatment planning. This data-driven approach can improve long-term patient outcomes and may contribute to research in orthopedic surgery.

[0066] The combination of robotics and AR technology in this system not only opens new avenues for further research and innovation but also has the potential to promote the popularization of advanced surgical techniques. Because the system's AR capabilities allow for convenient remote guidance from experienced professionals, surgeons in remote or resource-poor areas can benefit from its functionality. The practical application of this technology can improve patient care, increase surgical success rates, reduce complications, and / or accelerate patient recovery (e.g., patients undergoing orthopedic surgery).

[0067] Further details of some embodiments of the present invention are provided below.

[0068] Robot-assisted

[0069] In some embodiments, the system has a robotic arm employing sensors and actuators, providing surgeons with a high level of control and precision. The robotic arm can have multiple functions and can be used to perform a range of tasks (e.g., from precise positioning of surgical instruments to more complex operations (e.g., drilling for bone fixation and scalpel control for precise incisions)). The robotic arm can also hold imaging devices, providing real-time imaging data that can facilitate surgical success.

[0070] In addition to instrument positioning and real-time imaging, the robotic arm can also provide specialized functions for specific surgical needs. For example, the robotic arm can assist in inserting cannulas, precisely deploying surgical screws, and / or performing accurate bone cuts in laparoscopic surgery. The system can also help insert screws into bone for secure fixation and can assist in placing clips onto blood vessels or tissue, thereby reducing the risk of complications and improving surgical outcomes. In some embodiments, one feature of the robotic arm is its ability to measure depth, which is particularly useful for surgeries requiring precise incisions or holes. This feature ensures accurate depth of incisions or drill holes, thereby minimizing the risk of damaging underlying structures (e.g., anatomical structures). Whether suturing, cutting bone, or inserting screws, the robotic arm provides additional precision, which not only improves the quality of surgery but also significantly reduces the likelihood of postoperative complications. Whether suturing, cutting bone, or inserting screws, the robotic arm provides additional precision, which not only improves the quality of surgery but also significantly reduces the likelihood of postoperative complications.

[0071] Augmented Reality (AR) Headsets (e.g., Head-Mounted Displays)

[0072] The advent of AR in the medical field has ushered in a new era of surgical precision and patient safety. Surgeons wearing AR headsets (e.g., head-mounted displays) can gain enhanced vision with three-dimensional (3D) visual information, such as virtual images of anatomical structures, surgical plans, and / or real-time feedback from navigation sensors. Some embodiments of the present invention integrate optical navigation trackers into AR headsets, thereby improving the accuracy of superimposed digital information. AR systems can serve as tools to facilitate the precise positioning of instruments, whether for general surgical instruments or more specialized tools such as drills for bone fixation.

[0073] AR head-mounted devices can be particularly useful for tasks requiring high precision and spatial awareness. For example, they can assist in precise drilling by directly overlaying drilling paths onto the patient or surgical area. Similarly, they can assist in precise bone cutting by projecting cutting paths onto the surgical area. This technology is also useful when inserting screws and Kirschner wires into bone for fixation, providing surgeons with digital guidance overlaid onto the surgical area to ensure optimal placement. These features not only guide the surgeon but also reduce the risk of errors that could lead to complications.

[0074] In addition to guiding surgical instruments, the AR system can also highlight key anatomical structures (such as blood vessels, nerves, organs, etc.). This can significantly reduce the risk of accidental injury during surgery. Furthermore, the system can integrate vital signs, instrument readings, and other important data into the surgeon's field of vision. This real-time data integration capability helps the surgeon make immediate adjustments and informed decisions during surgery. Another feature is the measurement of the depth of incisions or orifices, which can provide additional safety and accuracy.

[0075] The AR system may also include features for intraoperative and postoperative monitoring. For example, during surgery, the position of the Kirschner wires can be compared with a virtual AR Kirschner wire image to adjust the bone to the correct fixation position. The same comparison can also be performed after surgery to verify that the bone has been fixed in the correct position. This two-stage application of AR technology can ensure the accuracy of the surgical procedure and can serve as a verification tool for assessing the effectiveness of interventions, thereby helping to improve long-term treatment outcomes for patients.

[0076] Navigation System

[0077] In some embodiments, the core of the surgical system lies in its navigation setup, which employs navigation sensors strategically placed in the operating room to track the real-time position and orientation of the patient and surgical instruments. The navigation sensor can input data into the central processing unit. The central processing unit can use algorithms to generate an accurate 3D spatial map. This ensures accurate instrument positioning (whether for general instrument positioning or more specialized tasks). The navigation system may be particularly well-suited for tracking drill coordinates, angular orientation, and / or penetration depth, making it a useful tool for bone fixation surgery. It can incorporate a range of specially designed methods and instruments to improve the accuracy of drilling operations, thereby enhancing the overall effectiveness of bone fixation techniques.

[0078] In addition to drilling, the navigation system can also be equipped with methods and algorithms to monitor the bone cutting process. This capability may be important for achieving surgical precision in bone cutting, which is a crucial factor in the successful execution of various orthopedic surgical procedures. The system can also provide a comprehensive operational framework for accurately tracking and inserting screws into the bone structure for fixation. This may include a detailed visualization of screw insertion coordinates, angular orientation, and / or penetration depth to ensure optimal bone fixation and contribute to better surgical outcomes. The navigation system may also be able to track data used to measure the depth of incisions or holes, increasing the accuracy and safety of the surgical procedure.

[0079] Workflow and Functions

[0080] The following is a workflow and function of one embodiment of the invention.

[0081] Preoperative Planning: Before surgery, the system is configured to import patient-specific diagnostic data, such as magnetic resonance imaging.(MRI) and computed tomography (CT) scan data. The attending surgeon can use a specialized software interface to develop a comprehensive virtual surgical plan. The plan not only specifies the optimal incision point, path, and instrument movement trajectory, but also includes calculated parameters for the Kirschner wire insertion angle and depth. In addition, the system can be designed to pre-calculate the postoperative Kirschner wire positioning, thereby tailoring a detailed surgical intervention plan to the patient based on the patient's unique anatomical features.

[0082] Intraoperative AR: At the start of the operation, the surgeon can be equipped with an AR head-mounted device. The system overlays the pre-set surgical plan onto the surgeon's real-time field of vision. This enhanced interface can overlay the virtual plan onto the patient's actual anatomical structure, thereby enhancing the surgeon's situational awareness. During the operation, the system allows real-time comparison of the Kirschner wire position and the AR virtual Kirschner wire image, thereby facilitating adjustments to achieve correct bone fixation.

[0083] Real-time navigation: Simultaneously, the system's navigation module is activated to continuously monitor the spatial position and orientation of surgical instruments. This real-time tracking data is processed and integrated into the AR display to update the surgeon's visual interface. The system allows surgeons to observe the real-time position of surgical instruments (including Kirschner wires) relative to a pre-set surgical plan, thereby ensuring accurate placement and alignment of surgical instruments.

[0084] Robot-assisted: The system also includes a robotic arm equipped with a haptic feedback mechanism. The robotic arm can be remotely controlled by the surgeon and can provide a haptic interface for precise instrument manipulation. The haptic feedback function is specifically designed to enhance the surgeon's ability to perform delicate surgical procedures, thereby achieving controlled and accurate movements during the operation.

[0085] Postoperative verification: After the operation, the system can perform a postoperative verification process. The system uses an AR interface to compare the actual postoperative Kirschner wire position with a pre-calculated virtual Kirschner wire image. This comparison can serve as a verification mechanism to confirm the accuracy of bone fixation. Any deviations can be quantified and analyzed to provide key data that can be used for postoperative assessment and future surgical planning. This feature is important for the system's goal of ensuring optimal surgical results through accuracy and verification.

It can track multiple instruments simultaneously and coordinate their movements through the robotic arm to prevent collisions and ensure efficient procedures. The tracking system and robotic arm can dynamically adapt to different stages of the surgery (e.g., incision, dissection, closure, etc.) and can optimize their functionality for each stage. Real-time tracking can be continuously compared with the preoperative plan to ensure consistency and can be adjusted accordingly. If any tracking error or system failure occurs, an emergency stop can be initiated, and the navigation system and robotic arm can be quickly recalibrated to resume the surgical procedure.
