Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interventional needle fixing devices are inconvenient to adjust angular positions, particularly in complex surgical scenarios, and often require manual adjustments that are time-consuming and limit the flexibility of needle angle adjustments.
Innovation Solution
An interventional needle fixing device with a displacement regulation mechanism, including a driving assembly, moving assembly, and limiting rods, combined with an interventional needle adjustment mechanism featuring a roll adjustment assembly, pitch adjustment assembly, and rotating assembly, allowing for precise control of needle angles and positions through motors and gears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the interventional needle is over-fixed to improve stability, then the needle position is stabilized, but the flexibility to adjust needle angle is greatly reduced
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the needle angle to be modified during the procedure. The adjustment structure includes movable components that can change the needle inclination angle while maintaining stable fixation during the actual intervention, resolving the contradiction between stability and adjustability.
Solution Approach 2:
The fixing device is divided into separate functional modules: a fixation component for stable positioning and an adjustment component for angle modification. This segmentation allows the needle to be firmly fixed during intervention while enabling independent angle adjustment through the separate adjustment mechanism.
2Ease of operation
If manual adjustment is used to achieve precise needle positioning, then adjustment flexibility is maintained, but time and energy consumption increase
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated driving mechanism. The driving assembly includes a motor that automatically adjusts the needle angle through transmission components, eliminating the need for time-consuming manual manipulation while maintaining precise control and flexibility.
3Device complexity
If traditional fixing devices are used to maintain simple structure, then device complexity is reduced, but the ability to meet diversified angle requirements is limited
Solution Approach 1:
The patent employs a nested structure where the adjustment mechanism is integrated within the fixation device body. The driving assembly, transmission components, and needle tube are arranged in a compact nested configuration, allowing wide angle adjustment capabilities while maintaining relatively simple overall device structure.

AI summary
The present disclosure provides an interventional needle fixing device for tumor clinical treatment, including an interventional needle adjustment mechanism. The interventional needle adjustment mechanism includes a roll adjustment assembly, a pitch adjustment assembly, a rotating assembly and a needle tube assembly. In the present disclosure, by arranging the interventional needle adjustment mechanism, when facing tumor lesions in different positions, doctors make the needle tube assembly realize left or right roll adjustment in a horizontal direction through the roll adjustment assembly, thereby accurately aligning a target area. At the same time, the pitch adjustment assembly can control the needle tube assembly to pitch upward or downward in a vertical direction, thereby meeting the diversified requirements of interventional needle angles in various complex surgical scenes, and improving the flexibility and accuracy of interventional needle puncture.
