Single Port Robotic Surgery Insertion Device Illumination and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instrument insertion systems for robotic surgery face challenges such as difficulty in use, reliability issues, and risk of damaging organs or tissues during insertion, due to incorrect positioning and limited range of motion within the body cavity.
Innovation Solution
A single port robotic surgery apparatus with an insertion device featuring a housing with multiple instrument channels, illumination for guiding instrument insertion, and a seal system to prevent fluid ingress, allowing for precise and safe insertion of instruments into the body cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple instrument channels are integrated into a single port housing, then the range of motion within the body cavity is improved, but the device complexity increases
Solution Approach 1:
Multiple instrument channels are nested within a single port housing structure, allowing each channel to be housed sequentially or concentrically within the same external port opening, thereby providing multi-directional access while maintaining a unified port interface
Solution Approach 2:
The single port housing is segmented into multiple independent instrument channels, each capable of receiving and guiding surgical instruments along different trajectories, enabling diversified surgical access through one port
2Ease of operation
If illumination devices are added to guide instrument insertion, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The illumination device is merged with the housing structure, where the illumination source and optical components are integrated directly into the port body, eliminating the need for separate external lighting equipment and reducing overall system complexity
Solution Approach 2:
The illumination device is positioned to automatically illuminate the instrument insertion path when instruments are being inserted, providing self-guided visualization without requiring additional manual lighting operations or external light sources
3Reliability
If seals are added to prevent fluid ingress, then the reliability is improved, but the ease of operation is worsened
Solution Approach 1:
Seals are pre-installed within the housing and instrument channel structures before use, creating ready-to-function barriers that automatically engage when instruments are inserted, eliminating the need for manual sealing operations during surgery
Solution Approach 2:
Flexible seal elements are used that can dynamically conform to the shapes of inserted instruments while maintaining fluid barriers, allowing instruments to pass through sealed channels without requiring rigid or complex sealing mechanisms
