Enhanced Haptic Control for Automated Surgical Alignment
Legal Citation
Summary of the Inventive Concept
This inventive concept improves the precision and safety of automated surgical alignment by incorporating advanced haptic control, real-time tracking, and 3D modeling. It addresses limitations in existing surgical systems, enhancing the surgeon's experience and reducing tissue damage.
Background and Problem Solved
The original patent, 'Automated alignment of a surgical tool,' describes a surgical system with a robotic arm, end effector, and tracking system. However, it lacks advanced haptic control, relying on simple tactile feedback. This limitation can lead to inaccurate alignment, tissue damage, and reduced surgical precision. The new inventive concept solves this problem by integrating enhanced haptic control, real-time tracking, and 3D modeling to ensure precise alignment and minimize tissue damage.
Detailed Description of the Inventive Concept
The enhanced haptic control system features a haptic device providing tactile feedback to the surgeon during the surgical procedure. A navigation system tracks the surgical tool and patient's anatomy in real-time, generating a 3D model of the patient's anatomy. The processor executes instructions to adjust the surgical tool's alignment based on the navigation system's tracking data and the 3D model, ensuring precise alignment. The system also includes a virtual boundary around the virtual trajectory of the surgical tool, providing tactile feedback to the surgeon when the tool approaches the boundary. This invention enables surgeons to perform procedures with increased precision, safety, and efficiency.
Novelty and Inventive Step
The new claims introduce advanced haptic control, real-time tracking, and 3D modeling, which are not present in the original patent. These enhancements provide a non-obvious improvement over the existing surgical system, enabling precise alignment and minimizing tissue damage.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include using different types of haptic devices, such as exoskeletons or tactile displays, or incorporating machine learning algorithms to improve the accuracy of the 3D model and tracking system. Variations could also include adapting the system for use in different surgical specialties, such as neurosurgery or orthopedic surgery.
Potential Commercial Applications and Market
The enhanced haptic control system has significant commercial potential in the medical device industry, particularly in the areas of robotic-assisted surgery and surgical navigation. The system could be marketed to hospitals and surgical centers, providing a competitive advantage in terms of precision, safety, and efficiency. The target industries could include orthopedic, neurosurgical, and general surgical markets.
