Solution Overview

Problem

Surgical devices currently fail to maintain a sterile environment for extracted patient organs and efficiently reinsert them into the body, often requiring manual pressure and risking contamination with non-sterilized foreign elements.

Innovation Solution

A surgical device comprising a deformable proximal and distal ring connected by a sleeve, with a sterile film that extends beyond the rings and includes a drawstring for reducing its circumference to form a sealed pocket for maintaining sterility and aiding organ reinsertion, using a flexible material that can withstand pressure and be easily manipulated for surgical procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional surgical devices are used to maintain an opening, then the incision can be kept open, but the extracted organs cannot be maintained in a sterile environment and require manual pressure for re-entry

Engineering Contradiction:

Improvesterility maintenanceVSAvoidorgan re-entry assistance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device divides the surgical field into two distinct zones: a sterile internal environment enclosed by the film barrier, and a non-sterile external environment. This segmentation allows organs to be extracted into the sterile pouch, maintained there, and then reinserted without exposure to external contaminants, eliminating the need for manual handling and pressure application.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The film barrier acts as an intermediary element between the sterile internal cavity and the non-sterile external environment. This intermediary maintains the sterile field while allowing controlled passage of organs through the incision, solving both the sterility maintenance and ease of re-entry problems simultaneously.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual pressure is applied for organ re-entry, then organs can be pushed back into the cavity, but there is risk of contamination from non-sterilized hands or instruments

Engineering Contradiction:

Improveorgan re-entryVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device enables self-service organ re-entry by allowing the organ to be pushed from the sterile internal side against the film barrier. The film itself becomes the interface that facilitates re-entry without requiring external manual pressure, thereby eliminating contamination risk from non-sterile hands or instruments.

Inventive Principle:

Principle #25Self-service

3Reliability

If a film barrier is extended beyond the rings, then a sterile pocket can be formed, but the device structure becomes more complex

Engineering Contradiction:

Improvesterile environment maintenanceVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device utilizes a flexible film barrier that can be extended beyond the proximal and distal rings to create a sterile pouch. This thin film approach maintains sterility without requiring complex rigid structures, achieving reliable sterile environment maintenance with minimal added complexity.

Inventive Principle:

Principle #30Flexible shells and thin films
