Industrial PC for medical laser applications

REQUIREMENTS AND IMPLEMENTATION

HEITEC is supporting a leading eye laser company with innovative electronics development, testing technology, and the design and integration of medical PCs for customer applications. The laser in the system is used in refractive surgery to treat short-sightedness, farsightedness, astigmatism, and presbyopia.

During eye surgery, HEITEC’s medical PCs – preconfigured as per the customer’s specifications – provide physicians with a graphical user interface containing necessary information. The treating physician enters data into the PC to determine where to apply the laser and at what intensity. The PC then transfers this information to a treatment controller, which controls the laser. But HEITEC’s contribution of these system solutions doesn’t end with the mere provision of hardware: Based on special logistics services, HEITEC offers the customer long-term supply capability and product stability. In its development and production, HEITEC consistently implements all the restrictive processes applicable in medical technology. Developments for medical products are based on the EN ISO 13485, EN ISO14971, EN 60601-1, and EN 62304 standards. These standards apply to quality and risk management as well as safety, including essential features and the lifecycle processes of medical electrical equipment. With product design the job is not done. Medical equipment must generally continue to be operational over many years. This means that lifecycle management must be designed for the long term.

In terms of technology, a system solution was selected that includes a classic 19” industrial PC standard whose compact, robust structure is ideally suited for the sophisticated, high-availability, high-precision application as well as for complex software requirements. Nevertheless, some adaptations of the standard hardware were required in this case: For example, the customer wanted dedicated cutouts in the rear of the housing to provide additional connections for complex data processing. Ventilation was improved by means of a special bracket for graphic cards. The housing was also designed to be EMC-proof so as to minimise regulatory risks.
