Solution Overview

Problem

Current methods for deploying hernia patches during laparoscopic surgery lack articulation mechanisms, making it difficult to optimally position and orient the patch relative to the tissue, leading to increased trauma and longer recovery times.

Innovation Solution

An x-shaped or zigzag-shaped lateral patch deployment device with reversible deployment arms and wires allows for controlled, bidirectional deployment and orientation of the patch, enabling minimal invasive surgery with reduced tissue manipulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional open incision surgery is used to repair hernia, then effective corrective surgery is achieved, but patient trauma is increased and recovery time is extended

Engineering Contradiction:
Improvecorrective surgery effectivenessVSAvoidpatient trauma
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The surgical approach is segmented into two distinct methods: conventional open incision surgery for complex cases and laparoscopic minimally invasive surgery for suitable candidates. The laparoscopic method divides the surgical field into multiple ports, allowing targeted intervention without large incisions, thus reducing trauma while maintaining effectiveness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patch material is designed with local quality variations - different regions of the patch have different properties to match specific anatomical requirements. The patch can be selectively positioned and oriented to provide reinforcement where needed most, allowing effective repair with minimal tissue disruption

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If laparoscopic surgery with multiple ports is used, then patient trauma is reduced and recovery is accelerated, but patch positioning and orientation control becomes more difficult

Engineering Contradiction:
Improvepatient traumaVSAvoidpatch positioning control
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patch delivery system incorporates dynamic positioning capabilities with articulation mechanisms that allow the patch to be oriented and positioned precisely at the distal end of the delivery device. The system can be dynamically adjusted during surgery to achieve optimal patch placement and orientation relative to the hernia defect

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A specialized patch delivery device acts as an intermediary between the surgeon and the patch. This device provides mechanical advantage and control, allowing precise manipulation of the patch through the laparoscopic ports. The delivery device includes articulation and positioning mechanisms that translate surgeon inputs into precise patch placement

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If patch is deployed without articulation mechanisms, then device complexity is reduced, but patch orientation and positioning precision deteriorates

Engineering Contradiction:
Improvedeployment device structureVSAvoidpatch orientation precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The deployment device incorporates articulation mechanisms that provide dynamic adjustment capabilities. These mechanisms allow the patch to be oriented at various angles and positions relative to the delivery device axis, enabling precise positioning without requiring overly complex static structures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patch delivery system incorporates self-aligning features that automatically position the patch optimally once deployed. The articulation mechanisms are designed to naturally guide the patch into the correct orientation, reducing the need for complex active control systems while maintaining positioning precision

Inventive Principle:
Principle #25Self-service
