Pre-loaded Corneal Tissue Delivery Device for Small Incision Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corneal transplantation surgeries face challenges due to the complexity of donor tissue processing and preparation, requiring significant time and expertise, which limits the number of procedures that can be performed and results in variable outcomes.
Innovation Solution
A donor corneal tissue storage and delivery device that allows for pre-loading, storage, and transportation of processed donor tissue in a ready-to-transplant state, featuring a cannula, fluid channel, flexible support, and deployment mechanism to facilitate standardized processing and precise delivery during small incision corneal transplantation surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If donor tissue is processed and prepared during the surgery, then the practitioner can control the processing quality, but the time required for preparation limits the number of procedures that can be performed
Solution Approach 1:
The donor tissue is processed, prepared, and packaged in advance at a tissue bank before the surgery. The implant tool is pre-loaded with the processed tissue, allowing the surgeon to perform the procedure without time-consuming preparation during the operation, thus increasing productivity while maintaining processing quality through standardized pre-preparation protocols
2Manufacturing precision
If donor tissue is processed at a tissue bank apart from the surgery location, then standardization of processing can be achieved, but the complexity of storage and transportation increases
Solution Approach 1:
The system is divided into separate functional modules: a tissue bank for standardized processing, a specialized implant tool for storage and transportation, and a surgical site for implantation. The implant tool acts as an intermediate carrier that maintains tissue integrity during transport, enabling centralized processing while simplifying logistics through dedicated equipment design
3Reliability
If conventional penetrating keratoplasty is used, then full-thickness corneal replacement is achieved, but surface corneal incisions and sutures cause poor wound healing
Solution Approach 1:
The invention extracts and removes the problematic surface corneal incisions and sutures from the surgical procedure. By using a small incision approach and sutureless technique with the implant tool, the procedure achieves corneal replacement without creating surface wounds, thereby eliminating the source of poor wound healing while reducing overall surgical complexity
