Solution Overview

Problem

Traditional surgical marking methods fail to accurately present surgical information and planning paths, leading to increased difficulty and burden for surgeons during operations due to the need for frequent reference to medical imaging equipment.

Innovation Solution

A bi-layer surgical guideline marking layer comprising a transparent first layer and a second layer, with a receiving tank system and permeable membranes, that displays a third color when overlapped, providing a visual guide and attachment mechanism to the patient's body surface, along with optional features like instrument through holes, removable structures, and tactile markers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional surgical marking methods are used, then the surgical procedure can be performed, but the surgical accuracy is insufficient and the surgeon's workload increases

Engineering Contradiction:

Improvesurgical accuracyVSAvoidsurgeon's workload

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent creates a physical copy of the surgical planning path and anatomical features by printing the surgical path on a transparent marking layer. This copy is then attached to the patient's body surface, allowing the surgeon to reference the visual guide during surgery without repeatedly checking imaging equipment, thereby improving surgical accuracy while reducing workload

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The transparent marking layer acts as an intermediary between the surgical planning phase (with imaging equipment) and the surgical execution phase. It transfers the complex spatial relationship information from the imaging domain to a simple visual guide that can be directly observed during surgery, eliminating the need for constant switching between imaging equipment and surgical site

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If medical imaging equipment is used to confirm spatial relationships during surgery, then the position and angle relationship can be verified, but the surgeon must repeatedly switch attention between imaging equipment and operation site

Engineering Contradiction:

Improveposition and angle relationship accuracyVSAvoidtime for switching attention

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The surgical path and anatomical features are pre-visualized and printed on the transparent marking layer before surgery begins. This preliminary creation of the visual guide allows the surgeon to have all necessary spatial relationship information readily available during surgery, eliminating the need for repeated reference to imaging equipment and reducing attention-switching time

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If a single-layer marking layer is used, then the structure is simple, but the attachment security and visual clarity are insufficient

Engineering Contradiction:

Improvemarking layer structureVSAvoidattachment security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The marking layer is segmented into multiple functional layers: a transparent base layer for visual clarity, a middle layer containing the printed surgical path and anatomical features, and an attachment layer with receiving tanks and permeable membranes for secure fixation. This segmentation allows each layer to optimize its specific function while maintaining overall system simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses composite material structures combining transparent polymers with functional coatings and integrated attachment mechanisms. The receiving tanks with permeable membranes create a composite attachment system that provides secure fixation while maintaining visual transparency, improving reliability without significantly increasing complexity

Inventive Principle:

Principle #40Composite materials
