Solution Overview

Problem

Conventional gastric surgical restoration procedures involve high rates of post-operative complications due to the risk of leakage and infection from perforating the digestive tract, which requires significant sutures, staples, and pins, leading to irreversible tissue damage and prolonged hospitalization.

Innovation Solution

An implantable restraining device with a first and second engaging component, configured for laparoscopic insertion, featuring a connector that allows for adjustable positioning and suturing elements to securely engage the stomach without penetrating the tissue, using materials resistant to corrosion and capable of resorption for minimally invasive and reversible procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional surgical techniques are used to restore organs and tissues, then the tissue can be altered and restored, but the procedure requires incisions, pins, staples and significant sutures which cause tissue damage and increase infection risk

Engineering Contradiction:

Improvetissue restoration effectivenessVSAvoidinfection risk and tissue damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the need for traditional penetrating surgical instruments (staples, pins, significant sutures) from the restoration procedure. Instead, it uses a delivery device that inserts a restraining structure through a minimally invasive pathway, extracting the harmful penetration action from the surgical process while maintaining the tissue restoration capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a delivery device as an intermediary between the surgeon and the target tissue. This intermediary device enables the insertion and deployment of the restraining structure without requiring direct penetration of staples or pins into the tissue, thereby mediating the interaction to reduce tissue damage and infection risk

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If conventional gastric restoration procedures are performed with cutting and suturing, then the digestive tract anatomy can be altered, but the procedure results in high rates of post-operative complications requiring prolonged hospitalization

Engineering Contradiction:

Improveanatomical reconfiguration capabilityVSAvoidhospitalization duration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces the traditional mechanical cutting and suturing system with a minimally invasive insertion system. The delivery device uses mechanical advantage to deploy the restraining structure through a small access point, substituting the complex cutting-and-suturing mechanical process with a simpler insertion-and-deployment mechanism that achieves anatomical reconfiguration without extensive tissue manipulation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent segments the surgical procedure into distinct phases: insertion of the delivery device, deployment of the restraining structure, and removal of the delivery device. This segmentation allows the complex anatomical reconfiguration to be achieved through separate, minimally invasive steps rather than a single prolonged surgical intervention requiring extended hospitalization

Inventive Principle:

Principle #1Segmentation

3Strength

If significant sutures and staples are used to secure the restored tissue, then the tissue can be securely held, but the procedure becomes irreversible and permanently affects the restored tissue

Engineering Contradiction:

Improvetissue securing strengthVSAvoidprocedure reversibility

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The patent employs a dynamic restraining structure that can be adjusted, loosened, or removed after deployment. The structure transitions from a deployed state that provides secure holding to a removable state that enables procedure reversal. This dynamic capability allows the tissue securing strength to be maintained during the healing period while providing the option for reversal if needed, unlike permanent sutures and staples

Inventive Principle:

Principle #15Dynamics
