Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrosurgical medical instruments require separate power sources for the medical instrument and ancillary instruments like light sources or smoke evacuators, leading to clutter and increased operational complexity.
Innovation Solution
An electrosurgical assembly that combines a medical instrument with an ancillary instrument, powered by the same power source, using a rectifier to convert AC power into DC power for the ancillary instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power sources are used for the medical instrument and ancillary instruments, then each instrument can be powered independently, but the surgical site becomes cluttered and operational complexity increases
Solution Approach 1:
The patent combines multiple power sources into a single integrated power system. The electrosurgical generator includes a power source that can simultaneously power the electrosurgical instrument and ancillary instruments through a common electrical connection, eliminating the need for separate power sources and reducing surgical site clutter while maintaining reliable operation
Solution Approach 2:
The power source is designed with universal functionality to serve multiple purposes. It can power the electrosurgical instrument, illuminate the surgical site, and operate smoke evacuation systems all through one power source, making the system more versatile and reducing overall complexity
2Adaptability or versatility
If a rectifier is added to convert AC power to DC power for the functional element, then the functional element can be powered by the same power source, but the device complexity increases
Solution Approach 1:
The rectifier serves as an intermediary component that enables power compatibility between the AC-powered electrosurgical generator and the DC-powered functional element. By inserting this power conversion mediator in the electrical pathway, the system achieves adaptability to power multiple instrument types with a single power source
Solution Approach 2:
The patent merges the power conversion functionality into the existing power distribution system. The rectifier is integrated into the electrosurgical assembly, allowing AC and DC powered components to share a common power source through unified power management
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution declutters the surgical site, allows a clinician to operate both the medical instrument and ancillary instrument with one hand, and reduces operational and instrument costs by sharing the power source.
Implementation Method 1
a rectifier is electrically connected to both the power source and the functional element, and the rectifier is configured to convert the AC power signal from the power source into a DC power signal to power the functional element
