  The METRx™ Microdiscectomy System incorporates specially designed metal
tubes that allow surgeons to access a surgical area in a minimally invasive
manner. These tubes, called dilators, vary in diameter size from 5.3 mm
to 20.8 mm. The METRx™ Microdiscectomy System dilators are inserted sequentially
-- one around the other -- through the muscle to gradually separate, or
split, the muscle fibers, creating an opening sufficiently large enough
for surgical tools and instruments to be inserted.
The METRx™ X-Tube™ Retraction System builds on this technology by providing
more extensive access to the surgical area. By expanding at the base from
a diameter of 2.5 cm to 4.0 cm, the METRx™ X-Tube™ Retraction System provides
pedicle-to-pedicle exposure.
Features and Benefits
Expanding upon the innovative design of the METRx™ Microdiscectomy System,
the METRx™ X-Tube™ Retraction System offers:
Optimal Exposure
- Provides pedicle-to-pedicle exposure
- Allows surgeon to expand the operative field from a diameter of 2.5
cm to 4.0 cm
Enhanced Visualization
- Facilitates the use of multiple modes of visualization:
- Microscope
- Loupes
- Endoscope
- Naked eye
- Coupled with the Radiance X™ Illumination System, integrated light
source, provides an excellent source of visualization (whether working
with microscope, loupes, endoscope, or the naked eye), even eliminating
the need for a headlamp
Innovative Design
The
METRx™ System allows surgeons to insert a series of dilators through a
small incision, one around the other, to gradually separate the muscle
fibers until an appropriately sized corridor leading to the surgical area
is created. The surgeon then inserts a tubular retractor to hold this
operative corridor open, allowing for surgical tools and instruments to
be inserted.
The METRx™ X-Tube™ Retraction System builds on this technology by providing
more extensive access to the surgical area. Like inserting the tubular
retractors that come stock with the METRx™ System, the surgeon inserts
a METRx™ X-Tube™ retractor over the dilators, seats it flush with the bony
anatomy, and locks it in place with a flexible arm. The surgeon then removes
the dilators, establishing a tubular opening to the surgical area. By
inserting the METRx™ X-Tube™ Retractor System opener instrument into the
X-Tube™ retractor and enlarging the opening of the tube at its base, the
surgeon has the ability to expand this corridor up to 4.0 cm in diameter.
Broad Application
The METRx™ System is indicated for visualization of the surgical field
in any area of the body opened through incision during a surgical procedure.
The system provides a muscle-sparing approach to spinal surgery by allowing
surgeons to insert a series of dilators, ranging in diameter from 5.3
mm to 20.8 mm, through a small incision. The dilators are inserted, one
around the other, to gradually separate the muscle fibers and create an
opening sufficiently large enough for surgical tools and instruments to
be inserted.
The METRx™ X-Tube™ Retraction System builds on this technology by providing
more extensive access to the surgical area by expanding at the base from
a diameter of 2.5 cm to 4.0 cm, providing pedicle-to-pedicle exposure.
Indications
The METRx™ System is indicated for visualization of the surgical field
in any area of the body opened through incision during a surgical procedure.
When used in the cervical, thoracic, or lumbar spine, either from an anterior
or posterior direction, for example, the METRx™ System is intended to
aid surgeons in visualizing the surgical area and allowing them to perform
any type of surgical spinal procedure, such as the following:
- Repairing a herniated disc
- Visualizing the circumferential decompression of the nerve roots
- Aiding in the search and removal of nucleus material from a vertebral
disc
- Performing a spinal fusion
- Inserting spinal implants
The METRx™ System is also indicated for generic surgical use in the knee,
ankle, shoulder, hand, wrist, and temporomandibular joint (TMJ).
