Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The insertion of a steel needle into an affected limb is not visible to the patient, causing anxiety and fear, and making it difficult to secure the limb properly, which can be harmful.

Innovation Solution

A posture display method and system that uses a virtual guiding channel to match the relative position relation between a three-dimensional affected limb image and a guiding channel, allowing real-time display of the needle's posture on a monitor, facilitating patient understanding and reducing anxiety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the steel needle insertion process is performed without visibility to the patient, then the medical procedure can be completed, but the patient experiences anxiety and fear and cannot understand the current status

Engineering Contradiction:

Improvepatient understanding of insertion statusVSAvoidpatient anxiety and fear

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent creates a virtual three-dimensional image that copies and displays the real-time position and posture of the guiding channel and steel needle within the affected limb. This visual copy allows the patient to see what is happening inside their body during the insertion process, transforming the invisible procedure into visible information that reduces anxiety and improves understanding

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system continuously updates the virtual three-dimensional image based on real-time position data from the guiding channel, creating a feedback loop where the patient can see the current status of the insertion process. This real-time feedback mechanism keeps the patient informed about the progression and current state of the medical procedure

Inventive Principle:

Principle #23Feedback

2Reliability

If the patient cannot understand the insertion process, then the medical procedure can proceed, but the patient may exhibit irresistible limb movements that increase difficulty and risk

Engineering Contradiction:

Improvesafety of medical procedureVSAvoidease of securing the limb

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

By providing real-time visual feedback through the virtual three-dimensional display, the patient can understand what is happening during the procedure. This understanding reduces panic and irresistible limb movements, making it easier for medical personnel to secure and stabilize the limb throughout the insertion process

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The virtual three-dimensional image acts as an intermediary between the invisible insertion process and the patient's perception. This mediator translates the internal medical procedure into visible information, reducing the patient's fear response and making the procedure safer and easier to perform

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present application relates to a posture display method, a device and a system for a guiding channel, and readable storage medium. The posture display method of a guiding channel includes determining an original position relation between a three-dimensional affected limb image and a virtual guiding channel displayed in a monitor according to an original position relation between the guiding channel and an affected limb and obtaining posture change data of the guiding channel. The method further includes adjusting the posture of the virtual guiding channel based on the posture change data, so as to the relative position relation between the virtual guiding channel and the three-dimensional affected limb image matches with the relative position relation between the guiding channel and the affected limb.
