Interlocking Tissue Grips for Atraumatic Foreign Body Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting foreign materials from difficult body areas, such as the eye, cause patient discomfort and tissue damage, and are inefficient, often requiring anesthesia and difficult manual techniques.
Innovation Solution
A tissue securing device with interlocking components and a gripping mechanism allows medical professionals to securely hold a first tissue away from a second tissue, enabling efficient removal of foreign materials without cutting or permanently displacing the first tissue, using a member to maintain the position and facilitate treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional swabs and inspection mirrors are used to extract foreign materials from the eye, then extraction can be performed, but patient discomfort increases and anesthesia may be required
Solution Approach 1:
The device divides the extraction function into two separate components: a first component with first and second grips for securing tissue, and a second component with a third and fourth grip for maintaining tissue displacement. This segmentation allows each component to perform its specific function efficiently, reducing overall patient discomfort while maintaining extraction capability.
Solution Approach 2:
The device introduces a mechanical intermediary system (the interlocking grip components) between the practitioner's manual manipulation and the tissue, providing controlled, stable tissue displacement without requiring harsh manual techniques or anesthesia. The interlocking mechanism acts as a mediator that translates practitioner input into precise tissue positioning.
2Ease of operation
If blocking tissues are held back or cut to access foreign materials, then extraction becomes easier, but tissue damage occurs
Solution Approach 1:
The device employs dynamic, movable grip components that can be adjusted and repositioned to accommodate different tissue configurations and procedure requirements. The interlocking mechanism allows for flexible tissue displacement without requiring permanent tissue removal or cutting, enabling easy extraction while preserving tissue integrity.
Solution Approach 2:
The device changes the operational parameters of tissue manipulation by using controlled mechanical displacement through interlocking grips rather than permanent cutting or removal. This parameter change from irreversible to reversible tissue displacement eliminates tissue damage while maintaining extraction ease.
3Ease of manufacture
If manual techniques are used to wash out foreign materials, then extraction can be attempted, but the procedure becomes difficult and time-consuming
Solution Approach 1:
The device performs preliminary tissue displacement and securing actions before the actual foreign material extraction begins. By pre-positioning the tissue using the interlocking grip components, the practitioner creates optimal access conditions in advance, making the subsequent extraction process faster and more efficient.
Solution Approach 2:
The device replaces inefficient manual washing and manipulation techniques with a structured mechanical system of interlocking grips. This mechanical substitution provides controlled, precise tissue displacement that facilitates faster foreign material removal compared to traditional manual methods.
4Reliability
If multiple practitioners need to operate in confined spaces like the eye, then treatment effectiveness improves, but access becomes difficult
Solution Approach 1:
The device segments the tissue securing function into separate, non-interfering components that can be manipulated independently by multiple practitioners. The first component with its two grips and the second component with its two grips can be controlled separately, allowing team coordination in confined spaces without component interference.
Solution Approach 2:
The interlocking grip mechanism operates in multiple spatial dimensions, providing tissue displacement and securing capabilities that create access pathways for multiple practitioners working simultaneously in the confined ocular space, effectively adding dimensional freedom to the procedure.
