ENT Image Guided Surgery

FUSION™

Image-guided systems are essentially like GPS (global positioning satellite) systems for the anatomy of your head. These systems are used to aid the surgeon in the confirming the location of critical structures when the interior of the nose and sinuses is distorted by unusual anatomy or prior surgery.

To use the image-guidance navigation system, a CT scan of the sinuses, is performed using a specific navigation system protocol. For some systems, a special mask or markers are placed on your face during the scan to serve as reference points. The CT scan is transferred to a disk, which is then loaded into the image-guidance computer.

During surgery, a detection array or a mask is placed on the patient's head. The CT scan images loaded into the system are then calibrated to the patient's anatomy using set pre-set reference points, which may be the mask or markers or specific anatomic points on the face. The position of the sinus surgery instruments can then be tracked by the computer by integrating the information detected from the patient's pre-set reference points and comparing it to the information on the CT scan map.

Designed for sinus surgery and advanced ENT applications, Medtronic's surgical navigation system will enhance your confidence and ability to perform more thorough and challenging procedures. Providing 3-Dimensional visualization enables you to locate and avoid critical structures, such as the optic nerve and brain, while safely navigating your way to the diseased area.

Functional Endoscopic Sinus Surgery (FESS) Procedure Solutions & Benefits

When patients with sinusitis do not improve after repeated courses of antibiotics and reasonable trials of the other medications used to treat sinusitis, the otolaryngologist may recommend undergoing FESS. The recommendation will also be based upon the physical examination, nasal endoscopy and CT scan findings. The decision to perform surgery should be made only after carefully considering the risks and benefits.

There are several advantages to FESS over the open sinus procedures that preceded it. To begin with, the ability to see within the nose and sinuses is much improved. Open sinus procedures often required facial incisions with resulting visible scars and lots of nasal packing. With FESS, there are usually no visible signs that surgery has been performed since the surgery is almost always done completely through the nostrils. Recovery is usually faster and there is usually less postoperative pain and bleeding. Nasal packing is used infrequently in FESS.

The primary advantages to using our navigation solutions for FESS include:

  • Procedures are much less invasive than open surgical operations that were once standard
  • Precision is greater, resulting in lower risk to the patient
  • Patient discomfort is minimal
  • Procedure recovery time is shorter

Stryker Image Guided Surgery

At the heart of the Stryker Navigation system is the unique two-way communication between the computer and the instruments.

This feature provides multiple benefits in the operating room:

  • Instrumentation developed specifically for image guided surgery
  • Active tracking (LED based) for a high degree of accuracy
  • Two-way communication between the handpiece and the camera enables the surgeon to control the software remotely from the handpiece.
  • No touch-screens or additional personnel required to run the system.
  • Durability: Stryker Navigation System's instruments are fully autoclavable.

The Stryker Navigation System has been designed to simplify the registration process. Stryker offers an instant registration with an auto-registration mask and the traditional point to point registration with an optional surface match feature.

Registration

All registration steps are carried out with the pointer's virtual mouse. This saves time and allows the surgeon to stay focused on the patient.

  • You choose the registration scheme:
  • Automatic registration done with the Stryker ªMaskº auto registration system (fiducial-less: no image add-ons)
  • Paired points (sticky markers or anatomic landmarks)
  • Surface matching (fiducial-less: no image add-ons)

Skull Post Kit

The Skull Mounted Tracker Kit is designed for rigid fixation of a patient tracker to the skull in a minimally invasive way. This eliminates the need for rigid (e.g.Mayfield) patient fixation for navigation procedures.

Smart Camera

The navigation camera is the eyepiece of the navigation system and the most critical component for navigation success. Stryker is the only company that designs and manufactures its own navigation camera.With the Stryker Navigation camera you get:

  • A larger field of view for tracking the patient
  • More set-up and patient positioning flexibility in the OR
  • Two way communication between the camera and the hand pieces
  • High control of design and quality
  • Proven commitment to the navigation business
