Intended Use

The Acumen™ Surgical Navigation System is intended to assist the surgeon in providing orientation and reference information to anatomical structures during open or percutaneous orthopedic procedures. The Acumen™ System is indicated for use in surgical knee and hip procedures, in which the use of stereotaxic surqery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to fluoroscopy (hip procedures) or an imageless model of the anatomy (knee procedures). These procedures include, but are not limited to, knee and hip arthroplasty procedures.

Device Story

Acumen Surgical Navigation System assists surgeons during orthopedic procedures; provides orientation/reference information for anatomical structures. System utilizes passive markers (spheres) attached to instrumentation; infrared camera tracks marker position/orientation. Instruments used independently, attached to patient, or connected to implant preparation/insertion tools. Each instrument features unique passive marker geometry for identification by camera and software. System supports knee and hip applications; instruments are single-use. Surgeon views navigation output to guide surgical steps; facilitates precise implant placement. Used in OR; operated by surgeon/surgical staff.

Clinical Evidence

No clinical data. Substantial equivalence established via software verification and validation testing.

Technological Characteristics

Stereotaxic instrument system; utilizes infrared camera tracking of passive markers (spheres) on instrumentation. Instruments are single-use. Software-driven navigation; supports imageless (knee) and fluoroscopy-based (hip) workflows. Class II device.

Indications for Use

Indicated for patients undergoing orthopedic knee and hip procedures, including arthroplasty, where stereotaxic surgery is appropriate and rigid bony structures can be referenced via fluoroscopy or imageless anatomical modeling.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

Device Description: The Acumen™ Surgical Navigation System includes general instrumentation that is utilized with application specific software developed and supplied by Z-KAT, Inc. (Hollywood, Florida).

Passive markers (spheres) are attached onto the Acumen™ instrumentation. An infrared light source generated by the camera reflects off of the passive markers to allow their position and orientation to be identified. The Acumen™ instruments are used as: 1) an independent instrument, 2) connected to instruments, which are attached to the patient, or 3) connected to the associated implant preparation and insertion instrumentation.

All Acumen™ instruments will have a minimum of three (3) passive markers to be tracked by the camera system. They will also be rigidly connected to the instrumentation. Each Acumen™ instrument, utilized in the surgical procedure, will have a defined geometry of the passive marker position for a unique identification by the camera and software system.

The instruments can be utilized with knee and hip applications. The Acumen™ instruments are designed as one-time use components.

Intended Use: The Acumen™ Surgical Navigation System is intended to assist the surgeon in providing orientation and reference information to anatomical structures during open or percutaneous orthopedic procedures. The Acumen™ System is indicated for use in surgical knee and hip procedures, in which the use of stereotaxic surqery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to fluoroscopy (hip procedures) or an imageless model of the anatomy (knee procedures). These procedures include, but are not limited to, knee and hip arthroplasty procedures.
