Intended Use
The Mako System is intended to assist the surgeon in providing software defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures. The Mako System is indicated for use in surgical knee procedures in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to a CT based model of the anatomy. These procedures include: • Total Knee Arthroplasty (TKA) The implant systems compatible with the system: - · Triathlon Total Knee System (CR/CS/PS cemented and cementless primary) - · Triathlon Total Knee System (TS inserts cemented primary) - · Kinetis Total Knee System (CR/UC)
Device Description
The Mako System with the Total Knee Application is a stereotactic instrument that includes a robotic arm, an integrated cutting system, an optical detector, a computer, dedicated instrumentation, operating software, a planning laptop, and tools and accessories. The system's architecture is designed to support total and partial knee procedures and total hip procedures. With application specific hardware and software, the system provides stereotactic/haptic guidance during orthopedic surgical procedures by using patient CT data to assist a surgeon with pre-surgical planning, implant placement and interpretive/intraoperative navigation of the patient's anatomy. The Mako robotic arm, once configured for a specific application, can serve as surgeon's "intelligent" tool holder or tool guide by passively constraining the preparation of an anatomical site for an orthopedic implant with software-defined spatial boundaries.
More Information

Not Found

No
The description focuses on stereotactic guidance, robotic assistance, and software-defined boundaries based on CT data, without mentioning AI or ML algorithms for planning, navigation, or control. The "intelligent" tool holder description refers to passive constraint based on software boundaries, not AI-driven decision making.

No.

The Mako System is intended to assist the surgeon during orthopedic procedures by providing spatial boundaries and guidance, not to treat a disease or condition itself. It's a surgical tool, not a therapeutic device.

No

Explanation: The device is described as a "stereotactic instrument" and a "robotic arm" intended to "assist the surgeon" during orthopedic procedures by providing "spatial boundaries for orientation and reference information" and "stereotactic/haptic guidance." It is used for "pre-surgical planning, implant placement and interpretive/intraoperative navigation." These functions are procedural assistance and guidance, not diagnosis.

No

The device description explicitly lists multiple hardware components including a robotic arm, integrated cutting system, optical detector, computer, and dedicated instrumentation, in addition to the software.

Based on the provided information, the Mako System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In vitro diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Mako System's Function: The Mako System is a surgical assistance system used during orthopedic procedures. It uses imaging data (CT) and robotic technology to help the surgeon with planning, navigation, and preparing the anatomical site for implant placement. It does not analyze biological specimens.
  • Intended Use: The intended use clearly states it's for assisting the surgeon during orthopedic procedures by providing spatial boundaries and reference information to anatomical structures.

Therefore, the Mako System falls under the category of a surgical assistance or navigation system, not an in vitro diagnostic device.
