Integrated Surgical Instrument Lighting for Deep Wound Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical illumination technologies, such as shadowless lamps, struggle to provide adequate light to deep and narrow wounds, particularly those with substantial internal cavities, making it difficult to maintain a clear view during medical procedures.
Innovation Solution
An illumination apparatus is integrated into medical instruments, featuring a housing component with an illumination assembly that includes a light-emitting element and a light-guiding element, allowing direct illumination to the operating site, with options for detachable or fixed connection and disposable components to prevent reuse and infection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If shadowless lamps are used for surgical illumination, then general illumination is effective, but light cannot reach deep locations of wounds
Solution Approach 1:
The illumination system is segmented into multiple independent light sources, each integrated onto separate medical instruments. This allows light to be delivered from multiple positions and angles, enabling illumination to reach deep within wounds where a single shadowless lamp cannot effectively penetrate.
Solution Approach 2:
The illumination assembly is nested within the housing component of the medical instrument. The light-emitting element and light-guiding element are positioned within the instrument's structure, allowing the light source to be brought directly into proximity with the deep wound site, thereby achieving effective illumination at depth.
2Illumination intensity
If illumination apparatus is integrated into medical instrument, then direct illumination to operating site is achieved, but device complexity increases
Solution Approach 1:
The illumination assembly is merged with the housing component of the medical instrument. The light-emitting element, light-guiding element, and housing form an integrated unit that is attached to or becomes part of the instrument, providing direct illumination without adding separate standalone equipment.
Solution Approach 2:
The illumination apparatus is designed to be compatible with multiple types of medical instruments through standardized attachment mechanisms. The same illumination assembly can be integrated onto different instruments (scalpels, forceps, etc.), providing universal illumination capability across various surgical tools without requiring instrument-specific customization.
3Illumination intensity
If light-guiding element extends from accommodating space, then illumination reaches operating site, but risk of infection increases
Solution Approach 1:
The illumination apparatus or its key components (illumination assembly, light-guiding element) are designed as disposable single-use items. After one use, the entire illumination unit is discarded, eliminating the risk of cross-contamination and infection from repeated use. This allows the light-guiding element to extend fully to the operating site without concern for sterilization between uses.
Solution Approach 2:
The light-guiding element is extracted from the housing component as a separate, extendable portion that can reach the operating site while the main housing remains outside the sterile field. This separation allows the extending portion to be disposable while the housing can be reused, balancing infection control with illumination reach.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures clear visibility at the operating site by providing direct illumination, preventing obstruction, and reducing the risk of infection through disposable components, while being applicable to both reusable and disposable medical instruments.
Implementation Method 1
an illumination assembly (120) disposed within the accommodating space and provided with a channel (121) that runs along the longitudinal axis... a light-emitting element; and a light-guiding element disposed adjacent to the light-emitting element, the light-guiding element being configured to guide light emitted from the light-emitting element
Implementation Method 2
a light-guiding element disposed adjacent to the light-emitting element, the light-guiding element being configured to guide light emitted from the light-emitting element to the outside of the illumination apparatus
Implementation Method 3
the light-guiding element further includes a light diffusion agent... By adding the light diffusion agent to the light-guiding element, an illumination range and/or uniformity of illumination of the illumination apparatus can be expanded
