Solution Overview
Problem
During phacoemulsification surgery, post occlusion surges in the aspiration channel can cause traumatic consequences due to sudden changes in vacuum pressure, and existing connector modules for phacoemulsification handles lack efficient mechanisms for managing these surges.
Innovation Solution
An Anti-Vacuum Surge (AVS) system using a fast-acting solenoid valve with magnetic induction for power and data transfer between the AVS module and the console-side connector, which includes magnetic coils separated by an insulating separator to prevent electrical interference and ensure continuous operation even with misalignment, allowing controlled pressure adjustment to prevent surges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connections are used for power and data transfer in the connector module, then reliable power and data transmission can be achieved, but the system becomes vulnerable to moisture-related transmission issues and requires multiple individual module connections increasing complexity
Solution Approach 1:
The patent replaces traditional mechanical electrical connections with magnetic induction coupling. The first coil in the connector module and the second coil in the handpiece create a magnetic field that transfers power and data wirelessly, eliminating the need for physical electrical contacts and multiple individual connections while maintaining transmission reliability and preventing moisture-related issues
2Adaptability or versatility
If multiple individual module connections are used to transfer power and data, then complete functionality can be achieved, but the risk of moisture-related transmission issues increases
Solution Approach 1:
By substituting electrical contacts with magnetic induction, the patent eliminates the vulnerability to moisture while maintaining all necessary power and data transfer functions through the magnetic field coupling between coils
3Device complexity
If conventional connector modules are used without anti-vacuum surge protection, then the system remains simple, but traumatic consequences can occur due to uncontrolled vacuum pressure changes
Solution Approach 1:
The patent incorporates an anti-vacuum surge protection mechanism that detects vacuum pressure changes and activates a solenoid valve to close the aspiration channel before traumatic surge can occur. This preliminary protective action prevents harm while adding minimal complexity to the connector module

AI summary
Methods and systems provide provides a vacuum surge protection system or an Anti-Vacuum Surge (AVS) module and a console-side connector that form an energy (power) and/or data transfer system, which passes the energy and/or data using a magnetic field, via non-contact magnetic induction, between the console-side connector and the AVS module. The AVS module typically powers a medical tool, such as a phacoemulsification handpiece, for ophthalmic procedures, such as cataract removal.
