Conjunctival Tissue Closure Device Using Segmented Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for closing conjunctival tissue openings are either time-consuming, costly, or inadequate in withstanding tension, and there is a need for improved tissue closure devices and instruments that minimize patient discomfort and surgical time.
Innovation Solution
A surgical device comprising two mateable components with absorbable bodies and mating surfaces, along with an instrument featuring elongate arms with piercing elements, allows for rapid and secure closure of conjunctival tissue openings by aligning and connecting the components beneath the tissue, thereby capturing and securing the tissue between the mating surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional suturing methods are used to close conjunctival tissue, then tissue closure can be achieved, but surgical time increases and operational complexity increases
Solution Approach 1:
The closure device is divided into multiple independent components including a first component with a first closure element, a second component with a second closure element, and a bridge component. These segmented components can be independently positioned and secured to the conjunctival tissue, allowing the device to be installed more quickly and easily compared to traditional continuous suturing methods while maintaining effective tissue closure.
2Strength
If traditional adhesive methods are used to close conjunctival tissue, then closure can be achieved, but tension resistance is insufficient
Solution Approach 1:
The closure elements are pre-formed with engagement features that enable them to securely grasp and hold the conjunctival tissue before final securing. The first and second closure elements are designed with preliminary engagement capabilities that allow them to firmly anchor into the tissue, providing superior tension resistance and reliable closure compared to adhesive methods.
3Ease of operation
If simple closure devices are used, then device complexity is reduced, but ease of installation decreases
Solution Approach 1:
The bridge component serves as an intermediary element that connects the first and second components together. This intermediary structure simplifies the overall installation process by providing a straightforward connection mechanism between the closure elements, making the device easier to install despite having multiple components, as the bridge component mediates the assembly process.
