Case Study: Design and Development of Phaco-emulsifier system controller
Complete end to end design & development of a medical instrument.
Client
A medical distributor supplying equipment for cataract surgery. Client wanted to build an end to end product from design, development, manufacture, service & support.
Challenges
Background:
The client was from trading background and wanted to get into design, development & manufacturing. Was looking to develop a low cost import substitute since he had mechanical & manufacturing capabilities. Looking for a partner in electronics & firmware.
There was no technical /user documentation for the product since it was a reverse engineering project.
Problem Statement:
Client wanted to build his own product. Design & development capabilities were not his forte hence was looking for a technical partner.
Solution
Overview:
End to end development of electronics & firmware by adding new features. Platform used was Linux, Single board computer with ARM Processor.
Details:
Key components of the new product are:
- Foot pedal with charger having wired as well as Bluetooth communication.
- Controlling Ultra Sound power & wave pattern based on foot pedal.
- Control Irrigation / Aspiration flow using stepper control based peristaltic pump.
- 10″ LCD TFT with Touch Screen interface.
- Facility for multiple procedures Diathermy, Ultra Sound & Vitrectomy in single device.
- Audio feedback to identify current operation and alarms without looking at screen.
- Monitoring of critical inputs low fluid level, high vacuum & motor failure.
- Configuration save feature for each doctor for each type of procedure.
Benefits
Technology:
- Latest UX & UI
- Audio output to understand type of operation
- Process parameters are configurable
Business:
- Using B.A.T as end to end technical partner
- Modular structure for ease of production
- Support for regulatory compliance (ISO 13485/IEC 62304) processes & documentation
- Low cost import substitute
