Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical techniques for treating macular degeneration face challenges in supporting and manipulating excised eye tissue during transplantation procedures, requiring improved tools for precise handling and placement.
Innovation Solution
A tissue carrier device featuring ring-shaped members coupled by a live hinge joint with a through-hole for tool engagement, allowing for precise control and manipulation of the tissue segment, enabling both compressive and tensile forces to be applied for stable and accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transplantation procedures are used for macular degeneration treatment, then the surgical procedure can be performed, but the excised tissue segment is difficult to support and manipulate
Solution Approach 1:
A carrier device is introduced as an intermediary tool to hold and manipulate the excised tissue segment. The carrier includes a body with a cavity that receives and secures the tissue segment, along with a protrusion that can be grasped by surgical instruments. This mediator solves the problem of directly handling fragile tissue by providing a stable interface between the tissue and surgical tools.
Solution Approach 2:
The tissue segment is nested within the cavity of the carrier body, which itself is part of the larger carrier assembly. This nested structure allows the tissue to be protected and contained within the carrier, facilitating safe transport and manipulation during the surgical procedure.
2Ease of manufacture
If the tissue carrier uses a simple structure, then manufacturing is easier, but precise control of tissue position and orientation is compromised
Solution Approach 1:
The carrier is segmented into distinct functional components: a body with cavity for tissue holding, a protrusion for instrument engagement, and a live hinge joint for articulation. This segmentation allows each component to be optimized for its specific function while maintaining overall manufacturing feasibility through modular construction.
Solution Approach 2:
The carrier incorporates a live hinge joint that allows dynamic articulation between components, enabling the carrier to adapt its configuration during manipulation while maintaining precise control over tissue position. The hinge provides controlled movement without requiring complex fastening mechanisms.

AI summary
A device includes a first band, a second band, and a joint. The first band is configured as a first ring. The second band is configured as a second ring. The joint couples the first band and the second band in stacked alignment and having a gap therebetween. The joint has a thrust surface configured to receive an applied compressive force in a direction lying substantially within a plane corresponding to at least one of the first ring or the second ring. The joint has a tension surface configured to receive an applied tensile force substantially aligned on the direction. The joint is compliant about a rotary axis lying in the plane. The joint is substantially non-compliant about an axis out of the plane.
