Disposable Camera-Bridge Cannula for Integrated Instrument Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In minimally invasive surgery (MIS) procedures, the use of distinct camera bridges and instrument cannulas or ports leads to inefficiency and unnecessary expense due to their separate manufacturing materials and purposes, necessitating multiple placements for various surgical needs.
Innovation Solution
A disposable cannula that serves as both a camera bridge and instrument cannula, manufactured primarily from plastic, with features like a camera receptacle, fluid ports, and a cap with a valve or seal assembly, allowing versatile use for different surgical purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distinct camera bridges and instrument cannulas are used, then specific surgical functions are achieved, but device complexity and expense increase
Solution Approach 1:
The patent combines a camera bridge and instrument cannula into a single integrated device. The camera bridge portion includes a camera receptacle that can receive a camera, while the instrument cannula portion provides a separate lumen for instrument insertion. This merging eliminates the need for separate components while maintaining both camera visualization and instrument access functions.
Solution Approach 2:
The integrated cannula is designed to perform multiple surgical functions simultaneously: it provides camera visualization through the camera receptacle, instrument access through the separate lumen, and can be configured with valves and seals for fluid control. This multi-functional design allows a single device to replace multiple specialized components.
2Adaptability or versatility
If multiple separate components are used, then specific purposes are served, but expense increases
Solution Approach 1:
The patent merges the camera bridge and instrument cannula into one integrated component, reducing the total number of parts that need to be purchased, sterilized, and disposed of. This consolidation directly reduces material costs and operational expenses while maintaining all necessary functional capabilities.
3Adaptability or versatility
If multiple bridges and cannulas are placed, then various surgical needs are met, but time consumption increases
Solution Approach 1:
By integrating the camera bridge and instrument cannula into a single device, the surgical team can place one component rather than multiple separate ones, reducing the time required for setup and insertion. The integrated design allows simultaneous achievement of camera visualization and instrument access without requiring sequential placement of separate components.

AI summary
A minimally invasive surgery (MIS) cannula that is manufactured primarily from a plastic material such that it is disposable and that serves as both a camera bridge, to which a camera may be coupled, and an instrument or tool cannula or port, through which an instrument or tool may be used. The cannula optionally includes one or more ports to which an irrigating fluid line may be attached to enhance site visibility and access and a camera receptacle to which a camera can be affixed. When the camera is not used, a cap may be attached to the cannula using the camera receptacle and may include a valve or seal assembly or the like through which an instrument or tool may be used. The cap and valve or seal assembly or the like may also accommodate a camera and arthroscope attachment. Otherwise, the cap may simply seal the cannula.
