Integrated Biopsy Apparatus with Movable X-ray Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biopsy analysis procedures require separate X-ray equipment and patient repositioning, leading to increased inconvenience, risk of X-ray exposure, and potential diagnostic errors due to the need for additional appointments and separate sampling verification.
Innovation Solution
An integrated apparatus that allows for simultaneous biopsy sampling and X-ray analysis using a single system, enabling X-ray imaging of samples while the patient is still positioned, minimizing unnecessary X-ray exposure and ensuring consistent results by using a system with a movable X-ray source and detector that adapts to different operating conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate X-ray equipment is used for biopsy analysis, then X-ray imaging capability is ensured, but device complexity and patient inconvenience increase
Solution Approach 1:
The patent combines the X-ray source, detector, and biopsy sampling system into a single integrated apparatus. The X-ray source and detector are positioned to image the biopsy site while the biopsy needle remains in place, eliminating the need for separate imaging equipment and patient repositioning.
Solution Approach 2:
The apparatus performs multiple functions simultaneously: it conducts biopsy sampling through the biopsy needle while concurrently performing X-ray imaging of the same region. This multi-functional design allows one device to replace what previously required separate specialized equipment.
2Measurement precision
If patient repositioning is required for biopsy analysis, then imaging accuracy is improved, but patient discomfort and procedure time increase
Solution Approach 1:
The apparatus is configured in advance with the X-ray source and detector positioned to image the biopsy site while the patient maintains the sampling position. The geometry is pre-arranged so that accurate imaging can be obtained without requiring the patient to reposition after needle insertion.
Solution Approach 2:
The X-ray source and detector are designed to be movable relative to each other and to the biopsy needle, allowing dynamic adjustment of imaging angles while maintaining the patient's fixed position. This enables accurate imaging from multiple angles without patient repositioning.
3Measurement precision
If additional X-ray checks are performed, then sampling verification is improved, but X-ray exposure increases
Solution Approach 1:
The X-ray imaging is performed continuously during the biopsy procedure rather than as separate discrete steps. The same X-ray source used for initial imaging continues to image the sample location immediately after needle insertion, providing verification without requiring additional exposure events.
Solution Approach 2:
The same integrated apparatus that performs the biopsy sampling also performs the verification imaging, eliminating the need for separate checking equipment. This allows sampling verification using the existing X-ray exposure rather than requiring additional exposure from separate devices.
4Ease of manufacture
If biopsy sampling and X-ray imaging are performed separately, then procedural clarity is improved, but overall procedure time increases
Solution Approach 1:
The biopsy sampling function and X-ray imaging function are merged into a single operational sequence. The biopsy needle is inserted while the X-ray source and detector are positioned to image the same region, allowing both functions to be performed in parallel rather than sequentially.
Solution Approach 2:
The X-ray source and detector are pre-positioned relative to the biopsy needle before sampling begins. This preliminary configuration allows the imaging system to be ready immediately when the needle reaches the target, eliminating setup time between sampling and imaging steps.

AI summary
An apparatus and a method for analysing samples taken by biopsy, which make it possible to perform the analysis of these samples whilst the patient is still positioned in the position for taking samples, in such a way as to make the overall procedure for taking and analysing the samples faster, reducing the inconvenience for the patient and the risk of a new examination, and also reducing in the majority of cases exposure of the patient to X-rays.
