What defines a medical device?

• A. Any tool used exclusively for surgery
• B. Any article intended for human beings for diagnosis, prevention, or treatment
• C. Only surgical instruments used during operations
• D. Tools that are used for cosmetic procedures only

Answer: (B)

The definition of a medical device encompasses a wide range of tools and equipment intended for various functions related to human health. The correct answer highlights that a medical device can be any article meant for the diagnosis, prevention, or treatment of diseases in humans, regardless of the specific type of intervention—surgical, therapeutic, or diagnostic.

This broad definition allows for the inclusion of not just surgical instruments, but also devices like diagnostic imaging machines, implantable devices, and even simpler equipment like thermometers or blood pressure cuffs. The emphasis on "intended for human beings" underscores the regulatory aspect that differentiates medical devices from other tools.

The other options are too restrictive. Focusing solely on tools used in surgery overlooks the vast array of medical devices applicable in different scenarios, including outpatient care, rehabilitation, and even home health settings. Similarly, limiting the definition to only surgical instruments or cosmetic procedures disregards the integral role that a wide variety of devices play across the medical field.
