Solution Overview
Problem
Current video overlay systems for ophthalmic surgical apparatus require a physical electric data cable connection, limiting mobility and increasing the risk of equipment damage and injury, while also lacking customization options, time-code integration, display mode modification, and audio recording capabilities.
Innovation Solution
A wireless data transmission system that eliminates the need for a physical data cable, allowing user customization of data sets, time-coded video and digital file generation, display mode modification, and simultaneous audio recording, using a computer-operated video overlay console with a wireless data transmitter module and receiver, and an audio processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical electric data cable is used to connect surgical apparatus and video overlay system, then data transmission is reliable, but mobility is limited and risk of equipment damage and injury increases
Solution Approach 1:
The patent extracts the data cable from the system by implementing wireless communication between the surgical apparatus and video overlay system. The surgical apparatus includes a microprocessor that wirelessly transmits surgical parameters to the video overlay system, eliminating the physical cable connection and its associated hazards while maintaining reliable data transmission.
Solution Approach 2:
The patent replaces the mechanical cable connection system with an electromagnetic wireless communication system. The microprocessor in the surgical apparatus communicates surgical parameters wirelessly to the video overlay system using electromagnetic signals, substituting the mechanical cable interface with a wireless electromagnetic field-based transmission medium.
2Device complexity
If standardized data sets are used in video overlay system, then system complexity is reduced, but adaptability to different surgical needs is limited
Solution Approach 1:
The patent implements dynamic configurability in the video overlay system, allowing the operator to select and customize data sets based on specific surgical needs. The system can dynamically adjust which surgical parameters are displayed and overlaid on the video signal, transitioning from a fixed configuration to an adaptable, operator-selectable configuration without increasing overall system complexity.
Solution Approach 2:
The patent creates a universal video overlay system that can handle multiple types of surgical parameters and configurations through a single platform. The microprocessor-based surgical apparatus can transmit various parameters (irrigation flow rate, vacuum level, ultrasonic power, etc.), and the video overlay system can selectively display different combinations based on surgical procedure requirements, achieving multi-functionality without proportionally increasing complexity.
Data Source
AI summary
An improved computer based surgical video overlay system that allows relevant surgical data from a surgical apparatus to be combined as a graphic image with the video image of a surgical procedure in which the data from the surgical apparatus is sent wireless to the video overlay console. Elimination of the data cable between the surgical apparatus and the video overlay console is advantageous in an operating room environment. The same computer based surgical video overlay system runs computer program that occupies a user interface to allows definition of operation modes, input of relevant data, selection of data overlay graphic screen templates and various methods for customization. A time coded-data file is created and stored including all the relevant parameters of a surgical procedure. This file contains the same time-code included in the graphic image overlaid in the surgical video signal. An precise match can be performed between the recorded data on file and the surgical video recording. An audio pre-amplifier section is provided to include surgical apparatus meaningful sounds produced during surgery. The alternative embodiment considers the use of an embedded computer within the video overlay console making the system capable of standalone operation providing a user interface and data input/output capabilities.
