SUMMARY
The discussion focuses on triggering needle movement in medical devices using electrical impulses, specifically through the use of a solenoid and timer circuit. The solenoid mechanism holds the needle in place until the injection is complete, which takes three minutes, after which a timer activates the solenoid to retract the needle. The conversation highlights the need for cost-effective solutions, as using a motor is deemed too expensive for the application. Participants emphasize the importance of understanding the specific medical application to tailor the device's functionality.
