Dual-Scope Surgical Imaging for Coordinated Tissue Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical imaging systems struggle to recognize and convey critical anatomical structures and dimensions within a three-dimensional space intraoperatively, leading to incomplete views and inhibited decision-making by medical practitioners.
Innovation Solution
A surgical system incorporating a first and second scope device to transmit image data of internal and external scenes, a controller to merge these images, and a control system to determine interaction locations and instrument orientations, enabling enhanced visualization and control of surgical instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single imaging system is used to view the surgical site, then the system is simple and easy to operate, but it cannot recognize or convey concealed structures, physical contours, and dimensions within three-dimensional space
Solution Approach 1:
The patent combines multiple imaging systems (endoscopic camera inside the organ and laparoscopic camera outside the organ) into a single integrated surgical imaging system. The controller merges images from both cameras to create a composite view that displays both the internal lumen surface and external anatomical structures simultaneously, thereby reducing information loss without proportionally increasing system complexity
Solution Approach 2:
The patent transitions from two-dimensional individual camera views to a three-dimensional composite surgical field representation. By merging internal and external views with spatial registration, the system reconstructs the three-dimensional anatomical context, allowing surgeons to perceive depth, contours, and spatial relationships that cannot be obtained from single-plane imaging
2Loss of information
If multiple scope devices are used to capture internal and external scenes, then complete anatomical visualization is achieved, but the system complexity and difficulty of coordinating instrument locations increase
Solution Approach 1:
The system implements real-time feedback by continuously displaying the merged image that shows both internal and external anatomical structures with registered instrument locations. The controller processes images from multiple scopes and provides immediate visual feedback to the surgeon about instrument positions relative to anatomical landmarks, enabling dynamic adjustment and coordination without increasing detection difficulty
Solution Approach 2:
The controller acts as an intermediary that receives images from multiple scope devices, performs image processing and spatial registration, and outputs a coordinated merged view. This intermediary component automatically handles the complex task of aligning and integrating multiple image sources, eliminating the need for manual coordination while maintaining complete anatomical visualization
3Loss of information
If the imaging system displays only the current surgical view, then the display is simple and focused, but it cannot convey information about upcoming surgical procedure steps or intended interaction locations
Solution Approach 1:
The system performs preliminary actions by pre-planning the surgical procedure steps and pre-calculating intended instrument interaction locations. The controller uses the procedure plan to determine where instruments will interact with tissue in upcoming steps and displays these intended locations as overlays on the merged image, providing advance information to the surgeon without requiring complex real-time processing during the actual interaction

AI summary
Surgical systems are provided. The surgical system includes an energy applying surgical instrument configured to apply energy to a natural body lumen or organ. A first scope device is configured to transmit image data of a first scene within a field of view. A second scope device is configured to transmit image data of a second scene within a field of view. A controller is configured to receive the transmitted image data of the first and second scenes and to provide a merged image of first and second scenes, where the merged image facilitates coordination of a location of energy to be applied to an inner surface of a tissue wall at a surgical site relative to an intended interaction location of a second instrument on an outer surface of the tissue wall in a subsequent procedure step at the surgical site.
