Discectomy Navigation Ready Instruments and Universal Navigation Adaptor Set

The Discectomy Navigation Ready Instruments when used with the compatible Universal Navigation Adaptor Set are intended to assist the surgeon in locating anatomical structures to facilitate disc space preparation, including discectomy or bony resection. These are indicated for use in surgical spinal procedures, in which:
• the use of stereotactic surgery may be appropriate, and
• reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated navigation arrays.
These procedures include but are not limited to spinal fusion. The Discectomy Navigation Ready instruments can be pre-calibrated with the Brainlab Navigation System.

Universal Navigation Adaptor Set:
The Universal Navigation Adaptor Set (UNAS) is intended for use with the compatible DePuy Synthes Navigation Ready Instruments to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. These are indicated for use in surgical spinal procedures, in which:
• the use of stereotactic surgery may be appropriate, and
• reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated tracking arrays.
These procedures include but are not limited to spinal fusion. The DePuy Synthes Navigation Ready Instrument, when used with UNAS, can be pre-calibrated and/or manually calibrated with the Brainlab Navigation System, where other navigation systems require manual calibration and tracking arrays supplied by the navigation system manufacturer.

The Discectomy Navigation Ready Instruments when used with the compatible Universal Navigation Adaptor Set are intended to assist the surgeon in locating anatomical structures to facilitate disc space preparation, including discectomy or bony resection. These are indicated for use in surgical spinal procedures, in which: • the use of stereotactic surgery may be appropriate, and • reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated navigation arrays. These procedures include but are not limited to spinal fusion. The Discectomy Navigation Ready instruments can be pre-calibrated with the Brainlab Navigation System.

The Discectomy Navigation Ready Instruments are reusable instruments used for disc space preparation, including discectomy or bony resection. These instruments are designed for navigated and non-navigated use. Navigation of these instruments is achieved using the DePuy Synthes Universal Navigation Adaptor Set (UNAS) and associated navigation arrays. The instruments include Cobb Elevators, Curettes and a Bone Graft Delivery Device. The Universal Navigation Adaptor Set (UNAS) contains reusable spine surgical instruments used to aid in determining the correct location and trajectory of spinal instruments and implants. The UNAS has an interface between third-party navigation systems and the DePuy Synthes Navigation Ready Instruments. The UNAS can only be used with Brainlab and Medtronic StealthStation® navigation systems. The UNAS includes: • Brainlab compatible UNAS Navigation Arrays, • Brainlab compatible Navigation Rings and • Medtronic compatible Navigation Ring ST. The Navigation Rings and Navigation Ring ST mate with compatible DePuy Synthes Navigation Ready Instruments. These instruments include implant site preparation and implant insertion instruments as well as access and discectomy instruments.
