Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple punctures are performed to ensure comprehensive sampling, then sampling completeness is improved, but puncture time is prolonged and patient discomfort increases
Solution Approach 1:
The system performs preliminary three-dimensional reconstruction of the prostate structure and pre-plans multiple puncture trajectories before the actual biopsy procedure. This allows the medical practitioner to visualize and prepare all necessary puncture paths in advance, enabling comprehensive sampling to be completed more efficiently during the actual procedure without prolonged patient discomfort
Solution Approach 2:
The patent transitions from traditional two-dimensional ultrasound imaging to three-dimensional reconstruction and visualization of the prostate structure. This dimensional enhancement allows for better spatial understanding of target locations and puncture trajectories, enabling more precise and efficient multi-point sampling that reduces overall procedure time while maintaining comprehensive coverage
2Ease of operation
If puncture precision is low, then operational simplicity is maintained, but repeated punctures are required increasing procedure time and patient suffering
Solution Approach 1:
The system introduces a computer-aided guidance system as an intermediary between the medical practitioner and the puncture procedure. This intermediary provides real-time visualization of needle position relative to three-dimensional prostate models and pre-planned trajectories, enhancing puncture precision without requiring complex manual skills from the practitioner, thus reducing repeated punctures and procedure time
Solution Approach 2:
The system creates a virtual three-dimensional copy or model of the patient's prostate structure based on medical imaging data. This digital replica allows for precise planning and simulation of puncture trajectories before the actual procedure, enabling high precision puncturing that reduces the need for repeated attempts and minimizes patient suffering
3Device complexity
If real-time tracking of needle tip position is not enhanced, then system complexity is reduced, but tracking accuracy deteriorates making precise puncture difficult
Solution Approach 1:
The system employs an intermediary computational layer that processes sensor data and integrates it with the three-dimensional prostate model. This intermediary processing enhances needle tip position tracking accuracy by combining multiple data sources and applying spatial transformations, achieving high precision without requiring overly complex hardware modifications to the ultrasound or positioning systems
Data Source
AI summary
Disclosed are a prostate puncture guidance method, apparatus, device and system based on multi-modal fusion. The prostate model of the object to be examined and the ultrasonic probe model with at least one scanning plane are displayed in the same display area. Based on the real-time coordinate and ultrasound image information collected by the ultrasonic probe, the display area dynamically displays dynamic updates. Users may get the positional relationship between at least one scanning plane and the target identifier in the prostate model. This allows for quickly and accurately understanding the intersection between the scanning plane corresponding to the puncture plate installed on the ultrasonic probe and the target identifier. Additionally, through another display area showing the correlation between the specific puncture hole in the puncture plate and the target identifier, sampling can be quickly completed through the sampling device by penetrating the specific puncture hole.
