Double-Sided Needle Groove for B-Ultrasound Puncture Frames

Solution Overview

Problem

Current in vitro puncture frames require multiple accessories due to fixed or adjustable needle groove structures, leading to increased costs and resource wastage in B-ultrasound puncture operations.

Innovation Solution

A double-sided needle groove with axisymmetric outer contour, featuring fixed and adjustable needle slots on opposite sides, allowing for easy switching and compatibility with various needle diameters, along with rotating convex half shafts and a frame body design for efficient installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple needle grooves with different aperture specifications are equipped for different needle diameters, then the puncture frame can accommodate various puncture operations, but the number of accessories increases and costs increase

Engineering Contradiction:

Improvecompatibility with various needle diametersVSAvoidnumber of accessories

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple needle grooves with different aperture specifications into a single integrated needle groove structure. The needle groove includes a first needle groove portion and a second needle groove portion that can accommodate needles of different diameters, thereby reducing the number of separate accessories needed while maintaining versatility for different puncture operations

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The needle groove is designed to perform multiple functions by accommodating both fixed-angle and adjustable-angle needle insertions, as well as supporting different needle diameters through its dual-portion structure. This multi-functional design eliminates the need for multiple specialized accessories

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A double-sided needle groove, a frame body and a puncture frame, wherein the double-sided needle groove has an axisymmetric outer contour, and is provided at one side with at least one needle slot a (1) and at the other side with at least one needle slot b (2); and the needle slot b (2) is fan-shaped. The double-sided needle groove is provided with one or more needle slots a (1) having a fixed needle insertion angle and a needle slot b (2) having an adjustable needle insertion angle, and the needle slot a (1) and the needle slot b (2) respectively correspond to the diameters of puncture needles and may be designed to meet multiple width specifications. During the performance of a B-ultrasound puncture operation, based on operation requirements of a surgeon for a fixed or adjustable angle, there is only a need to switch front and back sides of the double-sided needle groove, thus avoiding the need for an additional puncture frame, and switch the needle slots according to the diameters of the puncture needles. As can be seen, the double-sided needle groove can be applied to various types of B-ultrasound puncture operations and can effectively reduce the number of accessories in the puncture operations, thereby providing fast installation, saving resources and reducing costs.
