Solution Overview

Problem

Current training tools for colonoscopy, such as clinical patients, silica gel simulated colon models, and pig intestinal models, suffer from low effectiveness and low simulation, particularly in simulating different types of polypus lesions and scenarios.

Innovation Solution

A high-simulation colonoscopy training model featuring a detachable polypus module with replaceable polypus models, allowing for simulation of various polypus lesions in different locations of the colon model, thereby enhancing the realism and versatility of training scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a silica gel simulated colon model is used for training, then the model structure is simple and easy to manufacture, but the simulation of polypus lesions is insufficient and cannot simulate different types of polypus in various parts of the body

Engineering Contradiction:

Improveease of manufactureVSAvoidsimulation of polypus lesions

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The training model is divided into a colon model and multiple detachable polypus models. The polypus models can be independently attached to different locations on the colon model, allowing various polypus types to be simulated by simply replacing the polypus models rather than manufacturing entirely different colon models.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The colon model is designed with multiple polypus replacing points at different intestinal segments (cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum). A single colon model can simulate multiple polypus scenarios by attaching different polypus models at these replacing points, making it universally applicable for training various polypus examination and treatment skills.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a pig intestinal model is used for training, then the structure similarity to human intestine is high, but the model lacks targeted lesions resulting in less effective training

Engineering Contradiction:

Improvestructure similarityVSAvoidtraining effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

While maintaining the overall structure of a pig intestinal model for anatomical similarity, targeted polypus lesions are added at specific locations (polypus replacing points) on the colon wall. This local addition of pathological features enhances training effectiveness without compromising the structural advantages of the animal intestine model.

Inventive Principle:

Principle #3Local quality

3Reliability

If clinical patients are used for training, then real hands-on training experience is provided, but surgical complications may occur due to unskillfulness and training cannot be planned in advance

Engineering Contradiction:

Improvehands-on training experienceVSAvoidsurgical complications

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A realistic pig intestinal model with detachable polypus models serves as a safe copy of the human colon. It provides authentic hands-on training experience for colonoscopy operations, polypus identification, and treatment procedures without the risks associated with real patients. The model can be repeatedly used for training purposes.

Inventive Principle:

Principle #26Copying

4Ease of operation

If existing colon models are used for training, then introductory operation training is possible, but they cannot meet requirements for inspection, identification, treatment, replacement and measurement of polypus

Engineering Contradiction:

Improveintroductory operation trainingVSAvoidpolypus operation training

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The polypus models are designed to be detachable and replaceable, transforming the static colon model into a dynamic training system. Different polypus models can be attached and detached as needed, allowing the model to adapt to various training stages from introductory operations to advanced polypus examination, identification, treatment, and measurement procedures.

Inventive Principle:

Principle #15Dynamics

AI summary

The present application relates to a model for training a high-simulation colonoscopy, and relates to the field of a medical training model. The model includes a colon model and a polypus model detachably mounted on the colon model. The colon model is opened and provided with polypus replacing points for mounting the polypus model. The polypus replacing points are provided on different intestinal segments of the colon model. The polypus replacing points are provided at a plurality of different positions in a circumferential direction of the colon model. This application has the effect of simulating a variety of polypus lesion training scenarios, which contributes to the efficient conduct of colonoscopy training.
