Solution Overview

Problem

Current biopsy systems lack an efficient method for marking biopsy sites for future reference, and existing marker deployment tools are not seamlessly integrated with biopsy devices for simultaneous tissue sampling and site marking.

Innovation Solution

A biopsy system comprising a probe with a needle assembly and a tissue sample holder, where the system includes a mechanism for deploying markers at the biopsy site using a plug in the tissue sample holder, allowing for simultaneous tissue sampling and site marking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate marker deployment tools are used, then biopsy site marking can be performed, but the process requires additional equipment and steps increasing device complexity

Engineering Contradiction:
Improvebiopsy site marking accuracyVSAvoidequipment integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the marker deployment function with the biopsy needle assembly by integrating a marker into the tissue sample holder. This allows the same device used for tissue sampling to simultaneously deploy a marker at the biopsy site, eliminating the need for separate marker deployment tools and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tissue sample holder is designed to serve multiple functions: it collects the tissue sample during biopsy and simultaneously serves as a vehicle for deploying a marker at the biopsy site. This multi-functionality resolves the contradiction by allowing one component to perform both tissue sampling and site marking without requiring additional equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If simultaneous tissue sampling and site marking are performed, then procedural efficiency is improved, but the mechanism requires integrated components increasing device complexity

Engineering Contradiction:
Improveprocedural efficiencyVSAvoidintegrated mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the tissue sampling and site marking operations into a single integrated process. The marker is positioned within the tissue sample holder such that when the holder is inserted to collect tissue, the marker is simultaneously deployed at the biopsy site, achieving both functions in one procedural step.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The marker is pre-positioned within the tissue sample holder before the biopsy procedure begins. This preliminary placement ensures that when the holder is inserted into the tissue, the marker is automatically deployed at the correct location without requiring separate positioning steps, thereby improving procedural efficiency.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If marker deployment is integrated with biopsy device, then time for separate marking is eliminated, but the tissue sample holder design becomes more complex

Engineering Contradiction:
Improvemarking procedure timeVSAvoidtissue sample holder design
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The marker deployment mechanism is merged with the tissue sample holder structure. The holder includes a chamber or compartment that contains the marker, and when the holder is inserted to collect tissue, the marker is simultaneously released or deployed at the biopsy site, eliminating the need for separate marking steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The marker is nested within the tissue sample holder structure. The holder contains a compartment or cavity that houses the marker, and during the biopsy procedure, the marker is released from this nested position to be deployed at the biopsy site, integrating both functions within a single component.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A biopsy system, including a probe set, a holster, and a user interface. The probe set includes a plurality of probes. Each probe of the probe set includes a probe body, a needle, a cutter, and a tissue sample holder. The tissue sample holder is in communication with the cutter to receive one or more tissue samples. The holster is selectively securable to each probe of the probe set. The user interface is in communication with the holster. The user interface includes a display. The user interface is configured to identify which probe of the probe set is secured to the holster when a selected probe of the probe set is secured to the holster.
