Biopsy Stabilizing Element with Segmented Movement System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biopsy sampling apparatuses face challenges in achieving high precision due to variability in the positioning and shape of the suspicious zone within the body, making it difficult to accurately target and sample lesions during X-ray analysis.
Innovation Solution
The apparatus incorporates a positioning surface with a stabilizing element and a movement system that allows for independent translational movements along multiple axes, enabling precise positioning of the biopsy probe relative to the stabilizing element and the body, facilitated by a control system that can be motor-driven or manual, and includes a window to expose the necessary sector of the body for sample collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stabilizing element is used to stabilize the body part during biopsy sampling, then the stability and positioning precision are improved, but the complexity of the device increases
Solution Approach 1:
The stabilizing element is divided into multiple independent stabilizing portions that can be selectively positioned. Each portion can independently contact different regions of the body part, allowing the system to achieve stable positioning without requiring a complex monolithic stabilizing structure. This segmentation enables the device to adapt to various body shapes while maintaining simplicity.
Solution Approach 2:
The stabilizing element serves multiple functions: it stabilizes the body part, defines the sampling region, and provides reference points for probe positioning. By integrating these functions into a single component, the device achieves high positioning precision without adding separate complex subsystems for each function.
2Manufacturing precision
If the probe positioning is made highly precise to ensure accurate sampling of the suspicious zone, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The stabilizing element automatically defines the sampling region and provides self-aligning features for the probe. The body part itself, when stabilized by the element, serves as the reference for positioning, eliminating the need for complex external positioning systems. This self-service mechanism maintains high positioning precision while simplifying the operator's task.
Solution Approach 2:
The stabilizing element acts as an intermediary between the body part and the probe positioning system. It creates a stable reference framework that simplifies probe alignment and positioning, allowing the operator to easily achieve precise sampling without complex positioning procedures.
3Reliability
If the stabilizing element has a large contact area with the body part to improve stabilization, then the stability is improved, but the ability to access the suspicious zone deteriorates
Solution Approach 1:
The stabilizing element is divided into multiple discrete stabilizing portions rather than a single large contact surface. This segmentation allows the element to contact multiple distributed regions of the body part for stable positioning, while leaving the suspicious zone and surrounding areas accessible for probe insertion and sampling operations.
