No
The description focuses on the pneumatic motor's mechanical function and speed control, with no mention of AI or ML.
No
The device is described as a surgical motor that powers cutting tools for bone dissection. It is an instrument used during surgery, not a device that itself provides therapy.
No
Explanation: The device description states its purpose is to "provide power to operate an assortment of rotating surgical cutting tools" for "bone dissection and other microsurgical applications." This indicates a therapeutic or surgical function, not a diagnostic one. Diagnostic devices are used to identify a condition or disease.
No
The device description explicitly states it is a "pneumatic motor" and describes its physical characteristics and operation, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "skull based bone dissection and other microsurgical applications." This describes a surgical procedure performed on the patient's body, not a test performed on a sample taken from the body.
- Device Description: The description details a "pneumatic motor" that powers "rotating surgical cutting tools." This is consistent with a surgical instrument, not a device used for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on laboratory testing.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device's function is to physically cut bone during surgery.
