Corneal Tissue Carrier with Nested Poly-cone Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corneal tissue graft handling and transportation methods are inefficient, leading to increased surgical time, potential tissue breakage, and excessive use of storage medium, which can result in higher costs and reduced surgical efficiency.
Innovation Solution
A corneal tissue assembly comprising a vial with a poly-cone insert, a collarless luer locking cap, and flexible tubing, allowing for secure support and transport of the graft, reducing the need for counter-resistive forces and minimizing storage medium volume, while enabling easy access and insertion during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional corneal tissue graft handling methods are used, then tissue security during transport is maintained, but surgical time increases and tissue breakage risk increases
Solution Approach 1:
The graft is pre-loaded into the carrier device and pre-sterilized before surgery. The carrier is prepared in advance with the graft secured inside, eliminating the need for time-consuming tissue handling and loading during the surgical procedure. This preliminary preparation directly reduces surgical time while maintaining tissue security through the protective carrier structure.
2Reliability
If traditional graft carrier designs are used, then tissue is protected during transport, but excessive storage medium is required
Solution Approach 1:
The graft carrier is designed as a nested structure where the graft is secured inside an inner chamber, which is then placed within an outer protective carrier. This nested design provides multiple layers of protection for the tissue while minimizing the volume of storage medium required, as each nested level uses its own minimal amount of medium rather than requiring a large volume to protect the graft directly.
3Stability of the object's composition
If secure graft fixation is used, then tissue stability is maintained, but device complexity increases
Solution Approach 1:
The carrier device is segmented into distinct functional components: an inner graft chamber with fixation elements, an intermediate sealing layer, and an outer protective shell. Each segment performs a specific function - the inner chamber secures the graft with minimal fixation points, the sealing layer maintains sterility, and the outer shell provides mechanical protection. This segmentation achieves tissue stability without requiring a monolithic complex structure.

AI summary
Assemblies for storing, handling, transporting, viewing, evaluating, and/or shipping corneal tissue are provided. The assembly includes a corneal tissue carrier within a vial, the transport vial removably coupled to a stabilization base, wherein the ease of access to the graft carrier allows administering the corneal tissue sample to a patient in rapid succession so that more surgeries can be performed by a single surgeon in a single day.
