Solution Overview

Problem

Conventional mesh implants for hernia repair and soft tissue defects face issues such as crumpling, prolonged surgical time, complications from staples and tacks, and difficulties in deployment and attachment, especially in robotic surgery, leading to high recurrence rates and patient discomfort.

Innovation Solution

A mesh implant device with a housing that deploys and secures the mesh implant using supports and fasteners, optionally with a suture to close the incision point, reducing surgical time and instrument use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional mesh implants are used for hernia repair, then the mesh implant can provide mechanical support and induce scar tissue formation, but the mesh implant may crumple up and lose its tissue supporting function over time

Engineering Contradiction:

Improvetissue supporting functionVSAvoidlong-term stability

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The mesh implant is divided into multiple struts or ribs that form a segmented structure. This segmentation prevents the mesh from crumpling by providing rigid support elements distributed throughout the implant, maintaining its shape and tissue supporting function over time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mesh implant combines different materials with complementary properties - typically a biocompatible base material combined with rigid strut elements. This composite construction provides both the flexibility needed for implantation and the structural rigidity to prevent crumpling and maintain long-term support.

Inventive Principle:

Principle #40Composite materials

2Reliability

If traditional surgical repair methods with multiple instruments are used, then the mesh implant can be securely attached, but the surgical time is prolonged and patient discomfort increases

Engineering Contradiction:

Improveattachment securityVSAvoidsurgical time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The deployment device integrates multiple functions into a single instrument - it holds the folded mesh implant, deploys it upon insertion, and provides initial stabilization. This merging of functions reduces the number of surgical steps and instruments needed, shortening surgical time while maintaining secure attachment.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mesh implant is pre-folded and pre-positioned within the deployment device before insertion. This preliminary preparation allows for rapid deployment once the device is inserted, eliminating the need for complex intraoperative manipulation and reducing surgical time.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If multiple incisions are made for instrument insertion, then the mesh implant can be properly deployed and attached, but the number of complications and patient pain increase

Engineering Contradiction:

Improvedeployment capabilityVSAvoidcomplications and pain

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The deployment device serves multiple purposes through a single incision: it acts as the delivery vehicle for the mesh implant, the deployment mechanism, and the initial stabilization tool. This multi-functionality eliminates the need for multiple separate incisions and instruments, reducing patient trauma and complications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mesh implant is nested within the deployment device in a compact folded configuration. This nesting allows the entire assembly to be inserted through a single small incision, then deployed in situ, avoiding the need for larger incisions or multiple access points.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Reliability

If the mesh implant is deployed using conventional methods, then it can be attached to tissue, but the deployment process is complex and requires multiple steps

Engineering Contradiction:

Improveattachment securityVSAvoiddeployment process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The deployment device is designed to automatically deploy the mesh implant upon insertion into the body cavity. The act of insertion itself triggers the deployment mechanism, eliminating the need for complex external manipulation or additional deployment steps, thereby simplifying the overall process while ensuring reliable attachment.

Inventive Principle:

Principle #25Self-service

AI summary

A mesh deployment device includes a hollow housing within which mesh connected to a series of supports is housed and then activated during deployment, which supports are removed from the mesh once the mesh is located on the target hernia area and the supports are retracted back into the hollow housing and out of the body cavity. The mesh deployment device may include an optional port closure suture system on the mesh, and may also optionally include a series of attachment means on the mesh to connected to the target body cavity location.
