Enhanced Token-Based Electrosurgical Instrument Activation System
Legal Citation
Summary of the Inventive Concept
A system that dynamically adjusts the electrosurgical signal based on real-time feedback from the surgical site, optimizing tissue interaction and minimizing thermal spread, thereby improving the safety and efficiency of electrosurgical procedures.
Background and Problem Solved
The original patent, 'Token-based electrosurgical instrument activation,' introduced a method for activating an electrosurgical instrument attached to a surgical robot arm using a token-based system. However, this system has limitations, such as potential token replay attacks, inadequate safety measures, and inefficient tissue interaction. The new inventive concept addresses these limitations by introducing real-time feedback, dynamic signal adjustment, and enhanced safety features.
Detailed Description of the Inventive Concept
The enhanced token-based electrosurgical instrument activation system consists of a token-based activation module, an electrosurgical connection unit with an integrated safety module, and a rolling counter. The token-based activation module dynamically adjusts the driving electrosurgical signal based on real-time feedback from the surgical site, optimizing tissue interaction and minimizing thermal spread. The electrosurgical connection unit with an integrated safety module automatically disconnects the electrosurgical instrument from the electrosurgical generator in response to a faulty or expired token, preventing accidental activation. The rolling counter increments at a predetermined rate, enabling the system to detect and prevent token replay attacks. The system ensures secure and efficient electrosurgical procedures.
Novelty and Inventive Step
The new inventive concept introduces a novel combination of real-time feedback, dynamic signal adjustment, and enhanced safety features, which are not present in the original patent. The inventive step lies in the integration of these features to improve the safety and efficiency of electrosurgical procedures.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include using machine learning algorithms to optimize the electrosurgical signal, integrating the system with other surgical instruments, or developing a cloud-based platform for remote monitoring and control.
Potential Commercial Applications and Market
The enhanced token-based electrosurgical instrument activation system has significant commercial potential in the medical device industry, particularly in the fields of laparoscopic and endoscopic surgery. The system's improved safety and efficiency features could lead to increased adoption and market share.
