Problem
Current surgical robots are limited to using only surgical devices specifically developed for them, making them costly and inflexible, as they cannot accommodate devices from other manufacturers, restricting the range of available surgical instruments.
Innovation Solution
A surgical device for transperineal biopsy designed with a connection interface that allows compatibility with any commercial robot, featuring a separation module for sterility and a moving device with an ultrasound probe, enabling precise control and positioning of surgical instruments through actuators and motion transmission elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical devices are developed specifically for a given surgical robot, then the reliability and precision of the surgical operation is improved, but the cost increases and the adaptability decreases
Solution Approach 1:
The patent implements a universal connection interface that allows the surgical device to be compatible with multiple different surgical robot systems. The connection interface includes standardized mechanical coupling elements, electrical connection terminals, and communication protocols that enable the same surgical device to interface with various robot platforms, thereby achieving multi-functionality and broad adaptability without compromising surgical reliability
2Manufacturing precision
If surgical devices are developed specifically for a given surgical robot, then the surgical precision is improved, but the device cost increases
Solution Approach 1:
The surgical device is divided into distinct modular segments: a standardized connection interface module, a surgical instrument module, and a control module. The connection interface is designed as a separate, reusable component that can be manufactured at scale with standard tolerances, reducing per-unit costs. The surgical instrument module maintains high precision requirements only where needed for the actual biopsy function, while the connection interface uses conventional manufacturing tolerances, thereby reducing overall manufacturing cost while preserving surgical precision
3Reliability
If a robot is limited to using only specific surgical devices, then the device reliability is improved, but the range of available instruments decreases
Solution Approach 1:
The connection interface acts as an intermediary layer between the surgical robot and the surgical device. It includes standardized mechanical coupling elements, electrical connection terminals, and communication protocols that enable reliable signal and power transmission while maintaining compatibility across different robot platforms. This intermediary interface ensures reliable device performance through standardized connections while simultaneously enabling a wide variety of surgical instruments to be used with any compatible robot system
