Solution Overview

Problem

Existing tissue approximation techniques are limited in their ability to bring tissue edges from different locations close enough to be joined together, which is necessary for effective healing in minimally invasive surgical procedures.

Innovation Solution

A device comprising multiple jaws that can be independently moved relative to a fixed element, allowing for the approximation and joining of tissue edges by grasping and piercing them with barbs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing tissue approximation techniques are used, then tissue edges in close proximity can be joined, but tissue edges from different locations cannot be brought together for joining

Engineering Contradiction:

Improveability to join tissue edgesVSAvoiddistance between tissue edges

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The device divides the tissue approximation function into multiple independent jaws (first jaw, second jaw, third jaw) that can operate independently. Each jaw can grasp and move tissue edges separately, allowing tissue edges from different locations to be brought together for joining, thereby resolving the limitation of existing techniques that could only join tissue edges already in close proximity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device introduces an intermediary mechanism (the multi-jaw structure with independent movement capability) that mediates between tissue edges at different locations. The jaws act as intermediaries to grasp, manipulate, and bring together tissue edges that would otherwise remain too far apart for direct joining

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple jaws are independently moved to grasp tissue edges, then tissue edges from different locations can be approximated, but device complexity increases

Engineering Contradiction:

Improveability to approximate multiple tissue edgesVSAvoidstructure of device with multiple movable jaws

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into multiple independent jaws (first jaw, second jaw, third jaw) that can be independently moved relative to a fixed element. This segmentation allows each jaw to independently grasp and manipulate tissue edges, providing the adaptability needed to approximate multiple tissue edges from different locations while maintaining a relatively simple overall structure through modular design

Inventive Principle:

Principle #1Segmentation
