Multi-view Laparoscopic Imaging System with Deployable Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laparoscopic surgery imaging systems limit the field of vision, resolution, and access to hidden areas, and existing solutions are either complex, not adaptable to existing endoscopes, or do not provide a comprehensive view of the operating field combined with specific zone visualization.
Innovation Solution
A multi-vision imaging system comprising a first imaging device, such as an endoscope, and a second imaging device with movable cameras that provide an overall view of the operating field, allowing the cameras to be deployed outside the tubular member for enhanced visualization without interfering with the endoscope's movements, and can be adapted to existing standard endoscopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional mono-endoscope is used, then the device is simple and easy to operate, but the field of vision is limited and hidden areas cannot be accessed
Solution Approach 1:
The imaging system is segmented into multiple independent imaging devices (first imaging device for stereoscopic vision, second imaging device for global vision) that can be deployed independently. Each device has its own optical path and imaging sensor, allowing them to capture different views simultaneously without interfering with each other's operation
Solution Approach 2:
The patent adds a new dimension of visualization by introducing a second imaging device with a different optical axis orientation. The second imaging device captures images from a broader angular range, adding a global vision dimension that complements the localized stereoscopic vision of the first device
2Area of stationary object
If stereoscopic vision devices with multiple cameras are deployed, then the field of vision is widened, but the cameras may come into contact with internal organs and compromise the surgical intervention
Solution Approach 1:
The second imaging device is nested within the trocartube structure, with cameras positioned inside the tubular member before deployment. The cameras are contained within a protective tubular structure that prevents direct contact with internal organs during insertion and positioning, only extending outward when needed for imaging
Solution Approach 2:
The trocartube serves as an intermediary structure that mediates between the imaging devices and the surgical field. The tube provides a protective barrier and controlled deployment mechanism, allowing cameras to be positioned safely without direct exposure to internal organs during the critical insertion phase
3Area of stationary object
If a monobloc architecture combining stereoscopic and global vision systems is used, then a wide global field of vision is guaranteed, but the system is very complex and constrained by the size of the body
Solution Approach 1:
The system is divided into separate functional modules: a first imaging device for stereoscopic vision and a second imaging device for global vision. These modules can be independently configured and deployed, reducing the complexity of integrating multiple functions into a single monobloc structure
Solution Approach 2:
The trocartube structure serves multiple functions: it acts as a protective sheath for the imaging devices, provides a deployment mechanism for extending cameras outward, and serves as the structural framework for mounting multiple imaging devices. This multi-functionality reduces the need for additional separate components
4Loss of information
If the endoscope is frequently repositioned to achieve different views, then hidden areas can be accessed, but significant time is lost during surgical procedures
Solution Approach 1:
The second imaging device provides continuous global vision coverage of the surgical field without requiring repositioning. While the first imaging device focuses on localized detailed views, the second device maintains an ongoing broad view, ensuring continuous visualization of the entire surgical area and hidden regions without interruption or time loss
