Solution Overview

Problem

Traditional surgical procedures cause significant trauma to tissues due to extensive incisions and prolonged recovery times, and existing visualization methods for internal tissues are expensive and potentially damaging, leading to poor diagnosis and extended recovery.

Innovation Solution

A fully integrated, sterilizable disposable tissue visualization device with a handle, elongated body, image sensor, and optical element that provides visual and tactile feedback, allowing for accurate positioning and minimally invasive procedures with reduced tissue damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional surgical procedures are used to access internal tissue sites, then adequate visualization and treatment capability are achieved, but significant tissue trauma, long incisions, and prolonged recovery time occur

Engineering Contradiction:
Improvevisualization accuracyVSAvoidtissue trauma
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device segments the surgical system into a minimally invasive external console and a percutaneous probe that delivers visualization and treatment capabilities through a small gauge needle, avoiding the need for large incisions while maintaining adequate tissue site access and visualization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional mechanical surgical instruments with a percutaneous probe system that uses optical fibers for visualization and delivers therapeutic agents or energy through the needle, substituting mechanical tissue manipulation with more precise, minimally invasive methods

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If MRI or other imaging modes are used to visualize internal tissue sites, then diagnostic information is obtained, but the procedures are expensive, time-consuming to schedule, and may potentially damage the tissue site

Engineering Contradiction:
Improvediagnostic informationVSAvoidscheduling time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The percutaneous probe acts as an intermediary that delivers optical fibers directly to the tissue site through a small gauge needle, providing real-time visualization without requiring external imaging equipment like MRI, thereby eliminating scheduling delays and reducing diagnostic information loss

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The device creates a direct optical copy of the tissue site through the optical fibers, allowing real-time visualization of the internal tissue environment without needing to schedule separate diagnostic imaging procedures, thus eliminating time loss and providing immediate diagnostic information

Inventive Principle:
Principle #26Copying

3Object-affected harmful factors

If minimally invasive percutaneous procedures are used, then recovery time and post-operative pain are reduced, but visualization of internal tissue sites becomes more difficult

Engineering Contradiction:
Improverecovery timeVSAvoidtissue visualization
Core Design Contradiction:
Object-affected harmful factorsVSDifficulty of detecting and measuring

Solution Approach 1:

The device nests the optical fibers and visualization system within a small gauge needle, allowing the complex visualization apparatus to be delivered through a minimally invasive percutaneous approach, thereby maintaining reduced recovery time while enabling adequate tissue site visualization

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from external imaging approaches to internal direct visualization by inserting optical fibers through the tissue, changing the dimension of access from external to internal, which maintains minimally invasive benefits while solving the visualization difficulty

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Measurement precision

If extensive diagnostic procedures are performed before treatment, then accurate diagnosis is achieved, but recovery time is extended and tissue damage increases

Engineering Contradiction:
Improvediagnosis accuracyVSAvoidrecovery time
Core Design Contradiction:
Measurement precisionVSDuration of action of moving object

Solution Approach 1:

The device merges diagnostic visualization and therapeutic treatment into a single percutaneous probe, allowing accurate diagnosis and treatment to be performed through the same minimally invasive access point, thereby eliminating the need for separate extensive diagnostic procedures and reducing overall recovery time

Inventive Principle:
Principle #5Merging (Combining)
