Solution Overview
Problem
Current methods for controlling the configuration and orientation of surgical instruments lack precision and efficiency, particularly in remote or hard-to-reach surgical sites, where traditional techniques struggle to accurately replicate the required spatial targets for procedures like orthopedic and dental surgeries.
Innovation Solution
A system utilizing 3D spatial data generated through scanning technologies to control a remotely located robot, which adjusts and locks patient-specific instruments to replicate the spatial target, allowing for precise manipulation and execution of surgical steps at the procedural site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional techniques are used to control surgical instruments at remote sites, then the setup is simpler, but the precision and accuracy of replicating spatial targets deteriorates
Solution Approach 1:
The patent uses 3D scanning to create a digital replica of the surgical site and spatial targets, then uses a remotely located robot to replicate these digital models in the physical world. This copying approach enables precise spatial target replication without requiring the surgeon to be physically present at the remote site, resolving the contradiction between precision and device complexity.
Solution Approach 2:
The patent introduces navigation software and 3D digital models as intermediaries between the surgeon's intentions and the remote robot's actions. The navigation software translates spatial target data into robot control commands, acting as a mediator that enables precise control without direct physical interaction, thus improving accuracy while managing system complexity.
2Productivity
If manually controlled instruments are used at procedural sites, then the system is easier to operate, but the efficiency and precision of complex surgical procedures deteriorates
Solution Approach 1:
The remotely located robot performs self-positioning and self-adjustment based on pre-programmed 3D spatial data and navigation software guidance. This self-service capability enables the robot to autonomously replicate spatial targets and perform surgical procedures with high efficiency, while the surgeon only needs to provide oversight and make high-level decisions, maintaining ease of operation.
Solution Approach 2:
The patent performs preliminary 3D scanning, spatial target definition, and procedure planning before the actual surgical procedure. This preliminary action prepares all necessary data and robot programs in advance, enabling the remote robot to execute complex procedures efficiently during surgery without requiring complex real-time control, thus improving productivity while maintaining ease of operation.
3Adaptability or versatility
If pre-procedural 3D data alone is used, then the planning is simpler, but the adaptability to actual procedural conditions deteriorates
Solution Approach 1:
The patent merges pre-procedural 3D data with intraoperative 3D scanning data to create a comprehensive and accurate representation of the surgical site. This combination allows the system to adapt to actual procedural conditions while maintaining the benefits of pre-planning, resolving the contradiction between adaptability and data processing complexity through integrated data fusion.
Data Source
AI summary
A method and system for controlling the configuration and/or orientation of an adjustable instrument using a remotely located robot. The remotely located robot is utilized in conjunction with replicated specifications of a three-dimensional (3D) dataset defining a spatial target within an object. The obtained information will be utilized to perform a step that will alter or manipulate the object using the adjusted instrument.
