These tools, often used in conjunction with torque verification procedures, ensure the quality and reliability of the finished products. In this section, we will explore some of these essential devices.
Break-over Wrenches
Break-over wrenches are precision torque tools commonly used in medical device manufacturing. They function by applying a specific amount of torque to a fastener and then ‘breaking over’ when the pre-set torque is achieved, reducing the risk of over-torquing. This tool is beneficial in the manufacturing of medical devices as it assures precise torque control, contributing to the quality and safety of the final product.
Cam-over Wrenches
Cam-over wrenches provide an additional layer of torque control, eliminating the possibility of over-torquing. Once the pre-set torque value is reached, the tool’s unique mechanism slips or ‘cams over,’ preventing additional torque from being applied. This precise control makes cam-over wrenches an ideal choice for medical device manufacturing, where adhering to exact torque specifications is vital.
DC Control Electric Screwdrivers
DC control electric screwdrivers are advanced torque tools that provide exceptional control and data output capabilities. They offer adjustable torque settings and real-time monitoring, making them suitable for high-precision and traceability applications. These tools play a crucial role in the medical device manufacturing industry, where accurate data and quality control are paramount.
Clean Room Screwdrivers
Medical device manufacturing often takes place in cleanrooms and controlled environments with low levels of pollutants. Clean room screwdrivers are designed to operate in these conditions without compromising the environment. They are often built from materials that limit particle generation and are corrosion-resistant. These attributes make them an essential tool in the assembly of medical devices, ensuring both the product’s quality and the cleanliness of the manufacturing setting.
Classifications of Medical Devices
Medical devices, as defined by the FDA, are classified into three primary categories – Class I, Class II, and Class III. This classification is based on the device’s intended use, the indications for use, and the potential risks they pose to the patient or user. The higher the risk associated with the device, the stricter the regulatory requirements for its production and usage.
Class I Medical Devices
Class I medical devices are those with the least risk to the patient and/or user. They are typically simple in design, have a history of safe use, and pose minimal potential for harm to the user. Bandages, examining gloves, and portable surgical equipment are a few examples of Class I devices. Key characteristics of Class I devices include:
- Least amount of regulatory control: These devices often do not require pre-market approval (PMA) or clearance.
- General Controls: Class I devices are subject to general controls, including establishment registration, good manufacturing practices, proper branding and labeling, and mandatory reporting of adverse events.
Class II Medical Devices
Class II devices are more complex than Class I and carry a moderate to high risk to the patient or user. These might include infusion pumps, powered wheelchairs, or pregnancy test kits. Key characteristics of Class II devices include:
- Special Controls: In addition to the general controls, these devices are subject to special controls, which may include special labeling requirements, mandatory performance standards, and post-market surveillance.
- Pre-market Notification 510(k): Most Class II devices require FDA clearance through the 510(k) pre-market notification process.
Class III Medical Devices
Class III is the most stringent medical device classification. These devices sustain or support life, are implanted, or present a potentially unreasonable risk of illness or injury. Examples include implantable pacemakers, HIV diagnostic tests, or automated external defibrillators (AEDs). Key characteristics of Class III devices include:
- Pre-market Approval (PMA): Class III devices typically require FDA approval through the PMA process, which is more rigorous than the 510(k) process.
