Adjustable Arthroscopic Resection Sheath for Clear Surgical View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current arthroscopic resection devices face issues with outer members obstructing the surgeon's view and requiring multiple devices or interchangeable parts, leading to increased costs and potential damage to cutting surfaces.
Innovation Solution
An arthroscopic resection device with an adjustable outer member that allows for longitudinal movement relative to the inner member via a tube and means such as a knob, ratchet, lever, or slidable button, enabling precise control over the outer member's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a longer outer member is used to protect surrounding tissue, then safety is improved, but the surgeon's line of site is obstructed
Solution Approach 1:
The outer member is made adjustable in length, allowing it to be extended or retracted as needed. This dynamic adjustment capability enables the outer member to provide maximum protection when safety is the priority, and to be shortened when the surgeon needs an unobstructed view, thus resolving the contradiction between safety and ease of operation.
2Adaptability or versatility
If multiple devices or interchangeable outer members are used, then resection capability is improved, but device complexity and cost increase
Solution Approach 1:
The device incorporates a single outer member that can be adjusted to multiple lengths, making it universally applicable for different resection needs. This eliminates the requirement for multiple separate devices or interchangeable outer members, thereby maintaining full resection capability while reducing device complexity and the number of components needed.
3Adaptability or versatility
If interchangeable outer members are used, then adaptability is improved, but the risk of damaging the cutting surface increases
Solution Approach 1:
The adjustable outer member design allows for smooth extension and retraction without the need to detach or replace components. This dynamic adjustment mechanism eliminates the risk of damaging the cutting surface that would occur during the attachment and detachment of interchangeable outer members, while still providing the adaptability needed for different surgical requirements.
