Solution Overview

Problem

Current cesarean section procedures face challenges with uterine exteriorization requiring additional personnel for immobilization, leading to increased costs, fatigue, and potential accidents, especially in crowded operating rooms.

Innovation Solution

A cesarean section assistant device using a vacuum assisted delivery device and surgical clamps to immobilize the exteriorized uterus, allowing hands-free operation and reducing the need for additional personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If additional personnel are used for uterine immobilization during cesarean section, then surgical stability is improved, but labor costs and operational complexity increase

Engineering Contradiction:

Improveuterine stabilityVSAvoidpersonnel requirements

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The device enables self-service immobilization where the vacuum-assisted delivery device and surgical clamps work together to secure the uterus without requiring additional personnel. The system uses the existing surgical team's hands-free operation to achieve stable uterine retraction, eliminating the need for dedicated immobilization assistants.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The vacuum-assisted delivery device serves as an intermediary mechanism between the surgical team and the uterus. It provides a hands-free method to achieve uterine retraction and stabilization, mediating the immobilization function that previously required direct manual manipulation by additional personnel.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If additional personnel are assigned for uterine immobilization, then surgical safety is improved, but operational costs increase

Engineering Contradiction:

Improvesurgical safetyVSAvoidoperational efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system enables the surgical team to perform uterine immobilization independently using the vacuum-assisted delivery device and surgical clamps, eliminating the need for additional paid personnel. This self-service approach maintains surgical safety while improving operational efficiency by reducing labor costs.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If manual uterine retraction is performed, then surgical control is improved, but operator fatigue increases

Engineering Contradiction:

Improvesurgical controlVSAvoidoperator endurance

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The patent replaces manual mechanical retraction with a vacuum-assisted system. The vacuum pressure provides continuous, hands-free uterine retraction force, eliminating the need for operators to continuously apply manual pressure. This substitution maintains surgical control while significantly reducing operator fatigue and enabling longer procedure durations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If more personnel are deployed for cesarean section, then procedural reliability is improved, but room density and accident risk increase

Engineering Contradiction:

Improveprocedural reliabilityVSAvoidaccident risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The vacuum-assisted delivery device and surgical clamps enable the existing surgical team to perform immobilization functions independently, reducing the number of personnel needed in the operating room. This self-service approach maintains procedural reliability while decreasing room density and associated accident risks.

Inventive Principle:

Principle #25Self-service

AI summary

Methods and apparatus for immobilizing an exteriorized organ. In one specific implementation, an immobilizing device may be used to secure an exteriorized uterus for post-delivery suture (instead of requiring a physician or their assistant to hold the organ for suture). In addition to reducing fatigue, the exemplary techniques described herein may have a host of other benefits. By relieving physicians, physician assistants, midwives, or family medicine providers, hospitals can redirect these professionals to attend to other patients, thereby optimizing patient care and increasing revenue streams.
