Description

[0001] The present invention relates generally to the field of medical devices and surgical planning systems. In particular, the invention relates to a guided implant planning system and an instrument adapter configured to support the precise positioning, alignment, and placement of implants during surgical procedures.

[0002] Implant-based surgical procedures, particularly in fields such as dental, orthopedic, and craniofacial surgery, require a high degree of precision in planning and execution to ensure optimal functional and aesthetic outcomes. Accurate implant placement is crucial, as even minor deviations from the planned position can lead to complications such as uneven load distribution, damage to adjacent anatomical structures, implant failure, or the need for revision surgery. Until now, implant placement has relied heavily on the clinician's skills and experience, often supported by two-dimensional imaging and manual measurements.While advances such as three-dimensional imaging, including computed tomography (CT) and cone-beam computed tomography (CBCT), have improved preoperative visualization, translating virtual planning into precise intraoperative execution remains a significant challenge. Existing guided surgery solutions attempt to bridge this gap by using surgical templates derived from preoperative planning data. However, such systems often have limitations, including a lack of adaptability during surgery, insufficient compatibility with different implant systems, complex instrumentation, and potential inaccuracies due to template misalignment or improper placement.Furthermore, many current systems lack seamless integration between planning software and physical instruments, limiting their effectiveness in real-time surgical environments. Additionally, conventional instruments used in implant procedures may not be optimally designed for integration with guided systems, leading to inefficient workflows and extended operating times. The absence of a unified system that combines guided implant planning with adaptable and compatible instruments continues to pose technical and clinical challenges. Accordingly, there is a need for an improved guided implant planning and instrumentation system that overcomes the aforementioned limitations, increases accuracy and reliability, and provides greater flexibility and integration between the planning and execution phases of implant procedures.

[0003] To solve this problem, the present invention provides a system for guided implant planning and an instrument adapter.

[0004] The system aims to provide an integrated solution for guided implant planning and instrumentation to improve the accuracy of implant placement.

[0005] The system aims to facilitate precise preoperative planning and the seamless implementation of the planned implant position in the intraoperative procedure.

[0006] The system aims to improve the alignment and positioning of implants through the use of an instrument adapter configured for guided procedures.

[0007] The system aims to reduce human error and dependence on the surgeon's skills by incorporating guided and / or computer-assisted surgical techniques.

[0008] The system aims to ensure compatibility with a wide variety of implant systems and surgical instruments, thereby increasing versatility and ease of use.

[0009] The system aims to provide a stable and reliable interface between planning data and surgical instruments.

[0010] The system aims to increase surgical efficiency by shortening operating time and simplifying procedural steps.

[0011] The system aims to minimize the risk of complications associated with inaccurate implant placement.

[0012] The system aims to enable adaptability during surgical procedures in order to compensate for intraoperative deviations.

[0013] The system aims to improve overall clinical outcomes by ensuring consistent and reproducible implant placement.

[0014] The present invention relates to a guided implant planning system and an instrument adapter configured to facilitate the accurate and reliable placement of implants during surgical procedures. The system integrates preoperative planning, image-based analysis, and intraoperative guidance to ensure precise implementation of the planned implant position in the actual surgical procedure. In one aspect, the system comprises a planning module configured to receive and process patient-specific anatomical data obtained from imaging techniques such as computed tomography (CT) or cone-beam computed tomography (CBCT). The planning module enables the creation of a virtual implant placement plan, including the determination of the optimal implant position, orientation, and depth based on anatomical constraints and clinical requirements.In another aspect, the system includes an instrument adapter configured to connect to surgical instruments and / or implant delivery tools. The instrument adapter is designed to align with the planned implant path and assist in guiding the surgical instruments during the implantation process. The adapter can be configured to ensure the correct positioning, stability, and alignment of the instruments relative to the anatomical site. Furthermore, the system provides a mechanism to transfer the virtual implant plan into a physical or guided framework for use during surgery.This can include surgical guides, alignment devices, or digitally assisted navigation components that work in conjunction with the instrument adapter to maintain accuracy throughout the procedure. The system can also be configured to support compatibility with multiple implant systems and surgical workflows, thereby enhancing flexibility and applicability across various clinical scenarios. Additionally, the system can incorporate features that allow for intraoperative adjustments while ensuring adherence to the planned implant parameters.

[0015] The present invention relates to a guided implant planning system and an instrument adapter that enables precise and efficient implant placement based on patient-specific anatomical data. The system combines preoperative planning with intraoperative guidance to improve surgical precision and clinical outcomes. In one embodiment, the system comprises a planning module containing at least one processor and memory in which executable instructions are stored. The planning module is configured to receive patient-specific anatomical data corresponding to a target implantation site. Such data may include image data acquired by computed tomography (CT), cone-beam computed tomography (CBCT), magnetic resonance imaging (MRI), and / or intraoral scanning.The planning module processes the received data to generate a three-dimensional representation of the anatomical examination area. The planning module is further configured to determine a virtual implant placement plan based on this three-dimensional representation. The plan includes parameters such as implant position, inclination, and depth relative to surrounding anatomical structures. In addition, the planning module can perform an anatomical analysis, including the identification of critical structures, the assessment of bone density, and the evaluation of spatial constraints, thereby optimizing implant positioning and minimizing surgical risks. In another embodiment, the planning module includes a graphical user interface that displays the three-dimensional representation of the target implantation site.The graphical user interface allows a clinician to select, position, and modify a virtual implant model. The clinician can adjust parameters such as implant size, orientation, and depth based on clinical requirements and patient-specific considerations. The system also includes an instrument adapter configured to couple functionally with one or more surgical instruments. The instrument adapter includes at least one guidance interface structured to align the surgical instruments along a predefined implant path derived from the virtual implant placement plan. The guidance interface limits the movement of the surgical instruments so that they essentially follow the predefined path during the surgical procedure.In one embodiment, the instrument adapter comprises a guide sleeve designed to receive a drilling instrument, an alignment channel designed to guide an implant placement tool, and a locking mechanism designed to secure the adapter relative to a surgical guide or anatomical reference. These structural features collectively ensure stability and precision during implant placement. In another embodiment, the instrument adapter is detachable from and can be attached to the surgical instruments without requiring any modification of the instruments. This improves the system's compatibility with existing surgical tools and provides flexibility in clinical applications. The system may further include a surgical guide fabricated based on the virtual implant placement plan.The surgical guide is designed to conform to a patient-specific anatomical surface and may include one or more guide openings aligned with the predefined implant path. The surgical guide works in conjunction with the instrument adapter to ensure accurate positioning and stabilization of the surgical instruments during the procedure. In another embodiment, the system includes a navigation module configured to provide real-time or near-real-time feedback regarding the position and orientation of the surgical instruments relative to the virtual implant placement plan. The navigation module may employ tracking technologies such as optical tracking, electromagnetic tracking, or sensor-based systems to monitor instrument movement and assist the clinician during surgery.During the procedure, the system translates the virtual implant placement plan into a guided intraoperative execution. First, patient-specific anatomical data is acquired and processed to create the three-dimensional model. The surgeon then defines the implant placement plan using the planning module. Based on this plan, the instrument adapter and, optionally, the surgical guide are prepared. During the surgical procedure, the instrument adapter guides the surgical instruments along the predefined path, ensuring that the actual implant placement corresponds precisely to the planned position. Thus, the present invention offers an integrated solution that increases surgical accuracy, reduces procedural errors, minimizes the risk of damage to critical anatomical structures, and improves overall clinical outcomes.Various modifications and variations can be made without departing from the scope of the invention as defined in the attached claims.
