Solution Overview
Problem
Endovascular surgery faces challenges with tangled wires, inefficient cleaning of reused wires, space utilization, waste management, and quantification of medical supplies, leading to longer surgery times and hygiene issues.
Innovation Solution
A tray system comprising an upper and lower tray with features like a wire path for cleaning, a sponge for wire cleaning, a waste cavity for liquid waste, and reservoirs for medicines and dyes, along with integrated storage solutions for instruments and supplies, ensuring efficient use of space and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wires are reused throughout surgery, then productivity is improved by reducing the need for new wires, but cleaning time increases leading to longer surgery times
Solution Approach 1:
The sponge is pre-positioned within the wire path and pre-moistened with saline from the reservoir before the wire needs to be cleaned. This preliminary preparation allows the wire to be cleaned immediately upon insertion into the tray, eliminating the need for separate cleaning steps and reducing surgery time.
Solution Approach 2:
The system performs self-cleaning through the integrated sponge and saline reservoir. When the wire is passed through the wire path, it automatically contacts the moist sponge which cleans the wire without requiring manual intervention or separate cleaning equipment, thus improving productivity while minimizing time loss.
2Ease of operation
If wires are left uncoiled on a large table, then ease of operation is improved for access, but the wires take up vital operating theatre space and may become entangled
Solution Approach 1:
The wire cavity provides a nested storage structure where wires are coiled within a confined space inside the tray. This nesting approach allows wires to be stored compactly without occupying large operating theatre space, while still being easily accessible when needed by simply lifting them from the cavity.
3Object-affected harmful factors
If waste liquid is absorbed by towels, then waste containment is achieved, but waste volume increases and disposal becomes more difficult
Solution Approach 1:
The waste cavity extracts and contains liquid waste directly at the source within the tray structure, separating it from the surgical field immediately. This prevents the need to use towels for absorption, thereby eliminating the volume increase that would occur with towel absorption and simplifying disposal by concentrating waste in a single contained space.
4Ease of operation
If a large surface area is provided for surgical instruments, then ease of operation is improved, but the tray size increases occupying more space
Solution Approach 1:
The tray design utilizes vertical dimension by stacking functional elements (upper tray with reservoir, lower tray with wire cavity and sponge) to provide comprehensive functionality without requiring excessive horizontal surface area. This dimensional approach maintains ease of operation for all instruments while minimizing the overall footprint occupied by the tray system.
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 tray system effectively cleans and stores wires, reduces waste volume, and facilitates easy disposal, while providing a compact and hygienic environment for endovascular procedures, enhancing surgical efficiency and reducing contamination risks.
Implementation Method 1
the sponge is located within the wire path such that wires can be inserted into any of the one or more apertures, pass through the sponge, along the wire path and into the wire cavity where the wires will coil
Implementation Method 2
the sponge is located under the saline reservoir and the saline reservoir comprises one or more holes in its base, the holes configured to drip saline onto the sponge to keep it moist

AI summary
A tray used during endovascular surgery includes an upper tray and a lower tray. The upper and lower trays are removably attachable from one another and each includes a first forward side, a second rear side, a third lateral side and a fourth lateral side. The upper tray includes a saline reservoir and the lower tray includes a wire cavity, a wire path and a sponge. The wire path connects the wire cavity with one or more apertures in the first side of the lower tray and the sponge is located within the wire path such that wires can be inserted into any of the one or more apertures, pass through the sponge, along the wire path and into the wire cavity where the wires will coil.
