Flexible Biopsy Holder for Precise Needle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biopsy devices require precise positioning and verification of needle placement, which can be challenging for practitioners to manage without compromising the device's stability and accessibility for imaging confirmation.
Innovation Solution
A flexible support system with interchangeable holder sections, including cradles and clips, and a tripod configuration, allows for adjustable positioning and secure holding of biopsy devices, enabling practitioners to verify needle placement without compromising the device's stability or accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the biopsy device is held manually during positioning, then the practitioner has flexibility in adjusting the device position, but the device stability and precision are compromised
Solution Approach 1:
A support device acts as an intermediary between the practitioner and the biopsy device. The support device includes a base section, a flexible central section with linkage units, and a holder section that secures the biopsy device. This intermediary structure provides both stability for precise needle placement and flexibility for position adjustment, resolving the contradiction between manual handling flexibility and device stability.
2Measurement precision
If the biopsy device is secured rigidly to maintain stability, then the device positioning precision is improved, but the accessibility for imaging confirmation and adjustment is reduced
Solution Approach 1:
The support device incorporates dynamic characteristics through its flexible central section composed of interconnected linkage units. This allows the device to transition between stable (secured) and flexible (adjustable) states. The holder section can securely hold the biopsy device for precise positioning while allowing easy removal and repositioning for imaging confirmation, thus resolving the contradiction between rigid security and operational accessibility.
3Stability of the object's composition
If a fixed support structure is used for the biopsy device, then the device stability is improved, but the adaptability to different positioning requirements is reduced
Solution Approach 1:
The support device is segmented into three main sections: a base section, a flexible central section with multiple linkage units, and a holder section. This segmentation allows each part to perform its specific function while working together as a whole. The flexible central section can be adjusted to different configurations, providing adaptability to various positioning requirements while maintaining overall device stability through the base and holder sections.
4Measurement precision
If the support system is made complex to provide adjustable positioning, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The support device is designed with multi-functionality to reduce overall complexity. The flexible central section with linkage units serves multiple purposes: providing structural support, enabling position adjustment, and allowing the holder section to be positioned at various angles and heights. This universal design achieves precise positioning without requiring multiple separate complex mechanisms, thus resolving the contradiction between positioning precision and device complexity.

AI summary
A support or holder for a biopsy device is disclosed. The support includes a holder section that grasps or otherwise supports the biopsy device, wherein the support may be configured with flexible support members that may be bent, flexed or articulated thereby allowing the practitioner to manipulate the support for re-positioning the biopsy device into a desired position where the biopsy device may then be actuated to acquire a tissue sample.
