Puncture Tool Slider Mechanism for Rotational and Axial Needle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture treatment tools struggle to effectively use both rotational and non-rotational methods for puncturing needles, making it difficult to suitably perform biopsies on varied tissues.
Innovation Solution
A puncture treatment tool with a slider mechanism that allows the needle tube to be moved axially without rotation or rotationally, by switching between engagement states with a cylindrical main body, enabling reliable use of both methods depending on tissue properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the puncturing needle is operated to move forward and backward without rotation, then the puncturing method is suitable for certain tissue types, but it becomes difficult to perform rotational puncturing when needed
Solution Approach 1:
The puncturing needle is designed with dynamic controllability, allowing the operator to switch between rotational and non-rotational movement modes depending on the tissue type. The needle can be rotated by hand or operated without rotation based on the specific biopsy requirements, making the device adaptable to different tissue characteristics while maintaining operational simplicity.
2Adaptability or versatility
If the puncturing needle is rotated during puncturing, then the puncturing method is suitable for certain tissue types, but it becomes difficult to perform non-rotational puncturing when needed
Solution Approach 1:
The needle design allows dynamic switching between rotational and non-rotational puncturing modes. The operator can manually rotate the needle during puncturing when the tissue type requires it, or maintain a fixed orientation when non-rotational puncturing is more suitable, thereby improving ease of operation across different tissue types.
3Adaptability or versatility
If a fixed puncturing method is used, then the device structure is simple, but it cannot adapt to varied tissue states requiring different puncturing approaches
Solution Approach 1:
The puncture treatment tool incorporates dynamic controllability features that allow the operator to adjust the puncturing method in real-time based on tissue characteristics. The needle can be rotated or held fixed depending on the tissue state, providing adaptability to varied tissue conditions without requiring complex automated control systems or multiple specialized devices.

AI summary
A puncture treatment tool includes a needle tube whose distal end is insertable into tissue, a cylindrical main body through which the needle tube is inserted, and a slider to which the needle tube is fixed and which is disposed so as to movable relative to the main body in the axial direction of the needle tube. The slider and the main body are configured to be capable of selecting from a first state in which the slider is movable in the axial direction relatively to the main body without rotating in the circumferential direction of the main body, or a second state in which the slider is rotatable in the circumferential direction by switching states of engagement between the slider and the main body.
