System):whereas GPS measures the term of a time signal with at least three
satellites to determine an exact position on a map, the navigation system
in an operating room visually shows the surgeon the exact location and
orientation of his surgical instruments. During minimally invasive procedures,
for example, the operation environment, which itself is not directly visible
anymore, can be seen on the monitor.
In surgical navigation the instruments are made identifiable for the navigation
system with individually aligned small marker spheres, so-called DRFs
(Dynamic Reference Frame). The infrared camera takes over the part of the
GPS satellite which constantly registers the instruments as well as the marker
spheres. In this way the navigation system always knows where each
instrument is located.
An x-ray image or manual referencing by scanning anatomical landmarks
on the patient serves as a map during many operations on which the position
of the instruments is shown. The navigation system now shows the “map
of the body” as well as the position of the surgeon`s instruments. Movements
of the patient are tolerated during operation as the patient is also marked
with optical reference points.
The surgeon receives very precise information on the position and valuable
help for exact positioning of the instruments. The surgeon still executes the
operation himself, while the navigation makes the operation easier and more
precise.
C-arm navigation creates more space in the operating room CAS innovations and ZIEHM IMAGING combine navigation and imaging. The CAPPA SPINE and CAOS products from the CAPPA product family are directly integrated into the mobile C-arms from ZIEHM IMAGING. Not only does this create more space and saves costs, but it also provides the operating surgeon with more flexibility. |
The CAPPA SPINE system for spine surgery enables simple planning
and quick placing of pedicle screws. The navigation is based on 3D data
of the spine recorded intraoperatively (e.g. with a Ziehm Vario 3D). Therefore,
the necessary reference points are attached to the patient in a minimally
invasive way which is a very patient-friendly method.
Based on the 3D data and with the help of an instrument, the surgeon
plans various trajectories in the data record. Afterwards he traces these
planned access ways with his operating instruments such as awl or drill.
During surgery the position of the instruments and of the screws can
always be followed on the monitor in real time.
At the same time CAPPA SPINE shows important information on the
monitor such as angle and drilling depth for the canal of the pedicle screw
three dimensionally and in relation to the anatomy. Thus the doctor has
complete control over the drilling process. Pedicle screws can be exactly
placed so that the risk of post-operative complications can be minimized.
CAPPA for orthopaedics The modules of the successful CAPPA product family for orthopaedic surgery are now also conveniently and space-savingly available in the Ziehm C-arm. The patient-friendly solutions for hip endoprosthesis comprise not only conventional prosthesis but also substance-maintaining surface prosthesis. CAPPA KNEE is a solution for knee endoprosthesis enables the operating surgeon to plan the complete surgery in advance and evaluate the expected outcome prospectively. |
