Solution Overview

Problem

In laparoscopic surgery, it is challenging for practitioners to visually recognize and accurately position the puncture guide on an ultrasonic probe due to its location on the back side of the subject, making it difficult to insert a puncture needle effectively.

Innovation Solution

The ultrasonic probe incorporates a radiation part that emits laser beams in specific directions, including one opposite to the ultrasonic wave emission direction, allowing practitioners to visually confirm the puncture guide's position on the body surface, facilitating the insertion of the puncture needle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the puncture guide is located on the back side of the ultrasonic probe, then the puncture needle can be inserted at various angles, but the practitioner cannot visually recognize the puncture guide position

Engineering Contradiction:
Improvepuncture angle flexibilityVSAvoidpuncture guide visibility
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent projects a virtual image of the puncture guide onto the body surface using light radiation. This creates a visual copy or representation of the hidden puncture guide position, allowing the practitioner to see where the puncture guide is located without directly observing the physical guide structure on the back side of the probe.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces light radiation as an intermediary between the puncture guide and the practitioner's visual system. The light projects the position information of the puncture guide onto the body surface, serving as a mediator that transfers spatial information from the hidden guide to the visible surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the puncture guide is hidden by the skin, then the ultrasonic probe can maintain its structural integrity, but it becomes difficult to determine the puncture position and angle

Engineering Contradiction:
Improveprobe structural integrityVSAvoidpuncture positioning accuracy
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The virtual image projection creates a visual copy of the puncture guide position on the body surface, enabling accurate positioning without compromising the probe's structural integrity or exposing the hidden guide structure.

Inventive Principle:
Principle #26Copying

3Device complexity

If no visual indication is provided, then the device structure remains simple, but the practitioner cannot easily ascertain the puncture guide position

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidpuncture guide position information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent uses optical projection to create a visual copy of the puncture guide position information on the body surface. This provides the necessary position information without requiring complex mechanical or electronic indication mechanisms on the probe itself.

Inventive Principle:
Principle #26Copying
