Transparent Forceps Tip for Eye Wound Visualization During Suturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wounds in the eye are difficult to visualize and suture due to fluid obscuration and tissue closure, complicating ophthalmological procedures.
Innovation Solution
A forceps with a transparent projection at the distal end that presses against the wound to displace fluids and enhance visibility, allowing for precise suture placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If conventional forceps are used to access the wound, then the surgical procedure can be performed, but the wound remains difficult to visualize due to fluid obscuration and tissue closure
Solution Approach 1:
The forceps incorporates a transparent or translucent projection at the distal end that acts as a visual aid. This projection allows the surgeon to see through it to the wound site, effectively changing the optical properties of the instrument to improve wound visualization. The transparent projection may have markings or color indicators to help identify wound location and orientation, directly addressing the difficulty of detecting the wound.
Solution Approach 2:
The transparent projection serves as an intermediary element between the surgeon's view and the wound site. It mediates the visualization by allowing light to pass through while providing a reference frame or visual cues that help the surgeon locate and assess the wound, thereby improving detection without interfering with the surgical procedure.
2Ease of operation
If the tissues are allowed to press closed naturally, then the wound may heal, but the wound location becomes obscured and difficult to access for suturing
Solution Approach 1:
The transparent projection is designed to be positioned and secured at the wound site before suturing begins. This preliminary action maintains the wound in an open, visible state throughout the suturing process, allowing the surgeon to accurately place sutures without the wound closing prematurely. The projection acts as a temporary stent or spacer that prevents tissue collapse during the critical suturing phase.
3Difficulty of detecting and measuring
If fluids are present around the wound, then the natural physiological environment is maintained, but the wound becomes difficult to see and locate
Solution Approach 1:
The transparent projection may incorporate visual indicators, markings, or color-coded features that remain visible despite the presence of fluids. These visual elements cut through the obscuration caused by fluids, allowing the surgeon to locate the wound accurately. The projection itself being transparent allows viewing through it while its surface markings provide contrast against the fluid background.

AI summary
Devices and methods to stabilize an eye and suture with wound visibility are shown. In selected examples, a forceps is shown that includes one or more transparent projections. In use, the one or more transparent projections can be concurrently pressed against the wound while holding an eye stable with gripping surfaces of the forceps. The one or more transparent projections and the gipping of the forceps work together to aid in a suture placement.
