Solution Overview

Problem

Current surgical training systems lack the ability to securely and repeatedly attach organ models to a containing structure for minimally invasive procedures, limiting the practice of laparoscopic and robotically assisted surgeries due to inadequate attachment mechanisms and insufficient dissection planes for realistic tool access.

Innovation Solution

A surgical training system featuring a model base with channels and connectors that allow for secure attachment of tissue models, including real or synthetic tissue, using hooks and compressible members, and optionally incorporating magnets, sensors, and tubes for simulating blood vessels, enabling realistic and repeatable training scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surgical models are used for training minimally invasive procedures, then training capability is provided, but the ability to securely and repeatedly attach organ models is insufficient

Engineering Contradiction:
Improveattachment securityVSAvoidrepeated practice capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The surgical model is divided into separate components: a model base representing the patient body wall and removable model inserts representing organs. This segmentation allows the organ models to be independently attached and removed for repeated practice while maintaining a stable base structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment mechanism uses dynamic elements including serpentine channels that provide flexible positioning paths, compressible elongate members that allow for secure engagement, and magnets that enable adjustable positioning. This dynamic design allows repeated attachment and removal while maintaining secure connection during training.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If current surgical models are used, then some training functionality is provided, but sufficient dissection planes for realistic tool access are not available

Engineering Contradiction:
Improvetool access realismVSAvoidtraining effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The model inserts incorporate specific dissection planes and tissue layers with different properties at different locations. These localized features provide realistic tool access paths that simulate actual surgical conditions, allowing trainees to practice proper instrument insertion and manipulation through appropriate tissue planes.

Inventive Principle:
Principle #3Local quality

3Reliability

If human cadavers are used for training, then realistic surgical practice is provided, but cost and limited opportunities are issues

Engineering Contradiction:
Improvetraining realismVSAvoidtraining repetition capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The surgical model creates a simplified copy of the human body structure with model base and organ inserts that replicate the essential anatomical relationships and tissue properties. This copy provides realistic training experience without the limitations of cadavers, allowing unlimited repetition and reducing cost while maintaining training effectiveness.

Inventive Principle:
Principle #26Copying
