Solution Overview

Problem

Current puncturing device stands are bulky, limiting the ability to use multiple devices in the same area, restrict doctor movement, and are not adaptable to different device sizes or orientations, making them unsuitable for varied medical procedures.

Innovation Solution

A stand with a base plate and adjustable legs that can be easily mounted and dismounted, featuring pivotable arms and locking mechanisms, allowing for flexible orientation and accommodation of various puncturing devices, enabling precise positioning and easy use of multiple devices in the same area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If puncturing guides are used to prevent needle tilting during control imaging, then needle stability is improved, but the device becomes bulky and prevents insertion of multiple puncturing devices in the same area

Engineering Contradiction:
Improveneedle stabilityVSAvoiddevice bulkiness
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The puncturing guide is divided into separate functional components: a base element for stability, a support element for angular positioning, and a holder element for device retention. This segmentation allows each component to be optimized independently and enables multiple guides to be positioned close together without interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide structure utilizes three-dimensional spatial arrangement with the base element having flat legs extending in multiple directions, creating stability in horizontal dimensions while maintaining vertical clearance. This dimensional approach allows compact positioning of multiple devices.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If puncturing guides are fixedly mounted on the puncturing site during the entire procedure, then needle positioning stability is improved, but doctor freedom of movement is restricted

Engineering Contradiction:
Improvepositioning stabilityVSAvoiddoctor freedom of movement
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The guide incorporates a releasable coupling mechanism that transitions from a fixed state during imaging to a movable state during procedure execution. The flat legs can be repositioned on the skin surface, and the holder can be released to allow needle withdrawal and guide removal, providing dynamic adaptability throughout the procedure.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If puncturing guides are designed for specific puncturing device properties, then device guidance precision is improved, but adaptability to different device types is reduced

Engineering Contradiction:
Improveguidance precisionVSAvoiddevice adaptability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The holder element is designed with a universal retention mechanism that can accommodate puncturing devices of varying diameters and configurations. The releasable coupling allows the same guide structure to work with different needle types (anesthetic needles, biopsy guns, etc.) while maintaining precise angular guidance through the support element's fixed orientation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
