Solution Overview
Problem
Optical fibers used for analyzing light phenomena during HF surgery can become dirty or shaded, leading to reduced or blocked light transmission, which can falsify light signal intensity and affect analysis results.
Innovation Solution
A device that allows for easy attachment and replacement of a light absorption device, such as an optical fiber, to a surgical instrument, ensuring that the light absorption unit can record light generated during the procedure without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fiber is used for light analysis during HF surgery, then light transmission can be recorded and analyzed, but the optical fiber becomes contaminated by blood, tissue fluid, smoke gas, and tissue particles, reducing or blocking light transmission
Solution Approach 1:
A protective sheath is introduced as an intermediary component between the optical fiber and the surgical environment. The sheath allows light to pass through to the optical fiber while preventing direct contact between the fiber and contaminants such as blood, tissue fluid, smoke gas, and tissue particles, thus maintaining light transmission reliability without compromising the light analysis function
Solution Approach 2:
The protective sheath is pre-installed on the optical fiber before the surgical procedure begins. This preliminary protective measure prevents contamination from occurring in the first place, countering the harmful effect of contamination before it can affect light transmission. The sheath acts as a pre-established barrier against blood, tissue fluid, smoke gas, and tissue particles
2Power
If high energy input (300 watts) is used during HF surgery, then effective surgical cutting and coagulation is achieved, but very high temperatures (greater than 300°C) develop at the electrode tip, potentially thermally damaging the optical fiber
Solution Approach 1:
The protective sheath serves as a thermal intermediary between the high-temperature electrode tip and the optical fiber. It allows the electrode to operate at high power (300 watts) and temperatures (greater than 300°C) for effective surgical cutting and coagulation, while the sheath prevents direct thermal contact that would otherwise damage the optical fiber, thus protecting the fiber from thermal damage
Solution Approach 2:
The protective sheath is pre-installed on the optical fiber before the high-power surgical procedure begins. This preliminary protective measure cushions the optical fiber against the thermal effects of high-power operation (300 watts) and high temperatures (greater than 300°C) at the electrode tip, preventing thermal damage before it can occur
3Ease of operation
If detachable attachment is used for the light recording device, then the device can be easily replaced and cleaned during operation, but the connection mechanism adds complexity to the device structure
Solution Approach 1:
A connection element is introduced as an intermediary component that facilitates detachable attachment between the light recording device and the surgical instrument. This connection element enables easy replacement and cleaning of the device during operation while keeping the overall connection mechanism simple and straightforward, thus achieving ease of operation without excessive complexity
Solution Approach 2:
The light recording device is segmented into separable components that can be detached and reattached during surgery. This segmentation allows the device to be easily replaced and cleaned without requiring complex disassembly procedures, achieving ease of operation while maintaining relatively simple device structure through modular design
