Universal Biopsy Probe with Locking Holster Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopsy systems lack interoperability between handheld, ultrasound-guided and fixture-based, stereotactic settings, as different devices require separate holsters and probes, limiting the versatility of probe usage across different settings.
Innovation Solution
Designing a biopsy system where a single probe can be effectively coupled with either a holster intended for handheld, ultrasound-guided or fixture-based, stereotactic use, through modifications such as rigid locking teeth and projections, allowing for universal compatibility and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate holsters and probes are provided for handheld ultrasound-guided and fixture-based stereotactic settings, then device functionality and operational reliability are improved, but device complexity and the number of components increase
Solution Approach 1:
The probe is designed with a universal interface that can be coupled with both handheld holsters and fixture-based holsters. The probe includes a body portion with a coupling mechanism that accepts different holster types, allowing a single probe design to serve multiple surgical settings and functions, thereby reducing overall system complexity while maintaining reliability
2Reliability
If separate holsters and probes are provided for different settings, then operational reliability is improved, but adaptability and versatility decrease
Solution Approach 1:
The probe incorporates a standardized coupling interface that enables compatibility with multiple holster types across different surgical settings. This universal design allows the same probe to be adapted for handheld ultrasound-guided procedures, fixture-based stereotactic procedures, and other configurations, significantly enhancing versatility while preserving operational reliability through maintained coupling integrity
Solution Approach 2:
The coupling mechanism between the probe and holster is designed to be dynamic and adaptable, allowing the probe to be securely coupled with different holster types through modular interfaces. This dynamic coupling capability enables the system to transition between different surgical configurations without requiring multiple specialized probes, thereby improving versatility while maintaining reliable connection in each setting
3Reliability
If multiple device configurations are used for different settings, then operational reliability is improved, but ease of operation and procedural simplicity decrease
Solution Approach 1:
By providing a universal probe design that can interface with multiple holster types, the system eliminates the need for surgeons to switch between different probe configurations depending on the surgical setting. This universality simplifies the biopsy procedure by allowing consistent probe usage across handheld, fixture-based, and other configurations, thereby improving ease of operation while maintaining reliability through standardized coupling mechanisms

AI summary
A biopsy device comprises a probe that is configured to couple with a holster. The probe comprises a needle, a cutter, and a body portion. The needle is rotatable and translatable relative to the body portion. The holster has a locking feature that is configured to prevent the needle from rotating relative to the body portion upon coupling of the probe with the holster. The locking feature may also be configured to prevent the needle from translating relative to the body portion upon coupling of the probe with the holster. The same probe may thus be used with a holster intended for use in a fixture-based, stereotactic setting, in which rotation and translation of the needle may be desired; and with a holster intended for use in a handheld, ultrasound-guided setting, in which rotation and translation of the needle may be less desired if not undesirable.
