Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional core biopsy devices face limitations in accurately retrieving larger caliber tissue samples, leading to increased trauma, pain, and difficulty in visualizing small lesions, which often necessitate invasive surgical procedures, and fail to accurately correlate tissue diagnosis with imaging diagnosis due to tissue damage and biopsy artifacts.
Innovation Solution
A biopsy device with a tubular coring and transport assembly that allows for multiple sample retrieval during a single insertion, featuring a beak assembly with rotating cutting elements that can core and part-off samples of varying lengths, and a mechanism for gentle tissue penetration and sample transport, enabling precise sampling and minimal trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional core biopsy devices are used to retrieve larger caliber tissue samples, then sample size is increased, but tissue trauma and biopsy artifacts increase
Solution Approach 1:
The biopsy device divides the tissue sampling process into multiple independent coring elements that can simultaneously or sequentially retrieve multiple tissue samples. This segmentation allows for adequate sample size while distributing the trauma across multiple smaller coring actions rather than one large traumatic insertion.
Solution Approach 2:
Multiple coring elements are nested within a single biopsy device housing, allowing them to be delivered through a single skin insertion. The coring elements can be sequentially deployed to retrieve multiple tissue samples while minimizing the initial traumatic penetration required.
2Quantity of substance
If conventional biopsy devices are used, then single sample retrieval is achieved, but multiple samples require multiple insertions increasing patient trauma
Solution Approach 1:
The biopsy device is designed with multi-functionality to retrieve multiple tissue samples through a single insertion. The device incorporates multiple coring elements that can be sequentially or simultaneously deployed, making it universally applicable for obtaining multiple diagnostic samples without requiring repeated patient procedures.
Solution Approach 2:
The device enables continuous tissue sampling action through multiple coring elements that can be sequentially activated within a single procedural session. This continuity eliminates the need to withdraw and re-insert the device between samples, maintaining the useful action of tissue retrieval while minimizing harmful repeated insertions.
3Measurement precision
If larger caliber samples are retrieved, then diagnostic accuracy is improved, but device complexity and procedure difficulty increase
Solution Approach 1:
The device segments the diagnostic sampling function into multiple specialized coring elements, each optimized for retrieving adequate tissue samples. This segmentation maintains diagnostic accuracy by ensuring sufficient sample size while managing device complexity through modular design of the coring elements.
Solution Approach 2:
Multiple coring elements are nested within a compact device housing, allowing the complex multi-sample retrieval capability to be contained within a manageable form factor. The nesting arrangement reduces overall device complexity by efficiently packing multiple functional elements within a single deployable unit.

AI summary
A biopsy device comprises a coring and transport assembly and a distal beak assembly. The distal beak assembly may be coupled to or near a distal end of the coring and transport assembly and may comprise at least one movable cutting element. The distal beak assembly may be configured to rotate about an axis, and assume at least a first open configuration operative to enable the at least one cutting element to core through tissue and a second closed configuration operative to enable the at least one cutting element to move through the tissue and to sever a cored specimen from the tissue.
