Medical Support Device for Multi-Needle Puncture Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical support devices for percutaneous puncture treatments face challenges in precisely positioning multiple needles without interference, as existing solutions either require reinstallation or are too large for use within medical imaging machines.
Innovation Solution
A medical support device with two rotational elements and interchangeable needle guides, allowing each needle to be inserted through distinct starting points without interference, by rotating the elements to defined positions based on image data for precise targeting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If instruments are inserted through the same insertion point using a fixed positioning mechanism, then the device size is reduced and can fit within existing imaging machines, but instruments interfere with each other when multiple puncture targets are treated
Solution Approach 1:
The needle guide is made rotatable relative to the positioning mechanism, allowing dynamic adjustment of the needle insertion angle and direction. This enables multiple needles to be positioned at different angles to reach multiple targets without physical interference, while maintaining a compact device structure that fits within imaging machines.
2Object-affected harmful factors
If a grid-like positioning unit is used to insert multiple instruments at different target positions, then instrument interference is avoided, but the device becomes large and cannot be used in existing imaging machines
Solution Approach 1:
The needle guide is nested within the positioning mechanism, with the needle guide rotating inside the positioning structure. This nested configuration allows the system to achieve multi-directional needle positioning capabilities without requiring a large grid-like structure, maintaining compact dimensions suitable for existing imaging machines.
3Device complexity
If the same needle guide is used for multiple puncture targets, then the device structure is simplified, but the needle must be removed and reinstalled for each new target
Solution Approach 1:
The needle guide is designed to rotate dynamically to different angular positions while maintaining its attachment to the positioning mechanism. This allows the same needle guide to sequentially guide needles to multiple different targets without requiring physical removal or reinstallation, significantly reducing procedure time.

AI summary
There is provided a medical support device for holding and positioning a needle. This device is particularly useful for positioning needles in a less invasive puncture treatment. This device comprises two rotational elements and at least one needle guide attached to a rotational element and. The needle guide guides the direction of insertion of a needle-like instrument and includes a guide portion that guides a needle or other needle-like instrument where the puncture point of the needle in a first position is different from the puncture point when the needle guide guides the needle in a second position.
