Solution Overview

Problem

Current medical ultrasound systems struggle to precisely insert injection needles due to two-dimensional imaging, leading to potential errors in targeting veins or arteries, especially for unskilled operators, which can result in inaccurate treatments and safety risks.

Innovation Solution

A guide device for injection needle puncture that includes a body with a guide hole tilted at a specific angle, a sliding member to adjust the distance from the ultrasound apparatus, and a scales part to measure the separation distance, allowing for precise adjustment of the needle's entry path and angle, facilitating precise insertion even by unskilled personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a guide device with fixed angle guide hole is used, then insertion angle precision is improved, but adaptability to different target positions deteriorates

Engineering Contradiction:
Improveinsertion angle precisionVSAvoidadaptability to different target positions
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The guide hole is made rotatable relative to the body, allowing the insertion angle to be dynamically adjusted according to different target positions while maintaining precise angle control during the actual insertion process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide device is divided into a body and a rotatable guide part, allowing independent adjustment of the guide hole angle while maintaining the structural integrity and precision guiding function of the overall device

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the guide hole is made rotatable to adjust insertion angle, then adaptability to different target positions is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to different target positionsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide device is segmented into a body and a rotatable guide part, allowing angle adjustment functionality to be added without redesigning the entire device structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide hole angle is adjusted preliminarily before needle insertion based on the target position, allowing the device to adapt to different positions without requiring complex real-time adjustment mechanisms during the procedure

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is a guide device for injection needle puncture. The guide device for needle puncture according to one embodiment of the present invention comprises: a body; a guide part which has a guide hole provided therein so as to be tilted at a certain angle along the height direction, the guide hole allowing an injection needle to pass therethrough so that during injection needle puncture, the insertion angle of the injection needle can be constantly maintained; and a sliding member which is coupled to the body so as to be slidingly movable, wherein the spaced distance between the guide hole and a medical ultrasound apparatus is adjusted through relative movement of the body or the sliding member so that a target location into which the distal end of the injection needle is inserted can be located on entrance path of the injection needle.
