Enhanced Force-Sensed Surface Scanning Systems for Improved Accuracy and Efficiency

An enhanced force-sensed surface scanning system that dynamically adjusts the sampling scan path and predicts tissue deformation to improve the accuracy and efficiency of intraoperative volume model construction.

The original patent disclosed a force-sensed surface scanning system for registering an intraoperative surface-scanned volume model with a preoperative image-segmented volume model. However, the system had limitations in terms of accuracy and efficiency due to its inability to dynamically adjust the sampling scan path and compensate for tissue deformation. The new inventive concept addresses these limitations by introducing real-time force sensing data-based dynamic adjustments and tissue deformation prediction, enabling more accurate and efficient surface scanning.

The enhanced system comprises a surface scanning controller that dynamically adjusts the sampling scan path based on real-time force sensing data, optimizing the scanning process. The controller is further configured to predict and compensate for tissue deformation during the scanning process, improving the accuracy of the constructed intraoperative volume model. The system may also utilize machine learning algorithms to analyze the force sensing data and predict the surface deformation offset, refining the constructed model. Additionally, the robotic system may be equipped with a tactile sensor array to provide high-resolution force sensing data, enabling more accurate surface deformation offset calculations.

The new inventive concept introduces the novel feature of dynamic sampling scan path adjustment based on real-time force sensing data, which is not present in the original patent. This feature, combined with tissue deformation prediction and machine learning-based surface deformation offset calculation, provides a significant improvement in accuracy and efficiency over the original system.

Alternative embodiments of the inventive concept may include using different types of sensors or algorithms for force sensing and tissue deformation prediction. The system may also be adapted for use in various medical applications, such as laparoscopic or endoscopic procedures, or in non-medical fields like robotics or computer-aided design.

The enhanced force-sensed surface scanning system has significant commercial potential in the medical device industry, particularly in the areas of surgical navigation and intraoperative imaging. The system's improved accuracy and efficiency may also expand its market to other industries, such as robotics and computer-aided design, where precise surface scanning is crucial.
