Laser Console RFID Parameter Limits for Accessory-Safe Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical laser systems require frequent updates of control module databases to accommodate new accessories, risking damage to accessories, improper operation, and increased procedural complexity due to the lack of stored operating parameters.
Innovation Solution
A method involving a control console that receives information from a radio frequency identification tag (RFID) on a medical device to convert and set operating parameter thresholds, preventing laser energy delivery beyond these thresholds, using a processor to manage laser energy output based on a predefined matrix.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control module database is used to store operating parameters for accessories, then the laser energy delivery can be controlled, but the database needs frequent updates to accommodate new accessories, increasing device complexity and procedural time
Solution Approach 1:
The accessory device itself stores its operating parameters in an onboard memory, enabling it to self-identify and self-configurE the laser delivery system without requiring external database lookups or manual updates in the control module
Solution Approach 2:
The operating parameters are extracted from the central control module database and relocated to the accessory device's onboard memory, eliminating the need for frequent database updates in the control system
2Reliability
If operating parameters are stored in a control module database, then laser energy delivery can be controlled, but procedures are prolonged due to the need to update the database with new accessory parameters
Solution Approach 1:
The accessory device's operating parameters are pre-stored in its onboard memory during manufacturing, allowing immediate configuration upon connection without requiring time-consuming database updates or manual input during the procedure
Solution Approach 2:
The accessory automatically provides its own operating parameters to the laser delivery system through its onboard memory, eliminating the need for the control module to search or update databases during procedures
3Reliability
If the control module database lacks operating parameters for an accessory, then the accessory may be damaged or operate improperly, but storing parameters for all possible accessories increases device complexity
Solution Approach 1:
Each accessory device independently stores its own operating parameters in onboard memory, eliminating the need for the control module to maintain a comprehensive database of parameters for all possible accessory types
Solution Approach 2:
The operating parameters are extracted from the central control module database and placed in the accessory device itself, reducing the burden on the control system while ensuring parameter availability

Data Source
AI summary
According to one aspect, a method of controlling a laser delivery control console is disclosed. The method may include receiving at the control console electronically stored information from a radio frequency identification tag associated with a medical device. The method may also include converting, using at least one processor of the control console, the electronically stored information to a plurality of operating parameter threshold values. The plurality of threshold values may include maximum frequency values and maximum energy values for laser energy supplied by the laser delivery control console to the medical device. The method may further include preventing, in response to a command to adjust the energy or frequency of laser energy applied to the medical device, the delivery of laser energy with a frequency or energy value that exceeds one or more of the threshold values.
