What procedures are suitable for using EndoAssist?
EndoAssist can be used to hold the endoscope
in all minimally invasive procedures. The benefits that the system
provides are especially evident in operations that require very accurate
positioning of the scope e.g. minimally invasive mitral valve repair;
and/or where the position must be maintained accurately for long
periods of time e.g. endoscopic radical prostatectomy.
Using EndoAssist how do I change the position of
the endoscope during the operation?
EndoAssist is programmed to detect
and follow the movements of the surgeon’s head. The
surgeon wears a lightweight headband fitted with an infrared
emitter. The head position of the surgeon is detected by
a receiver unit and converted into motion of the robot, so
to move the view left, the surgeon simply glances to the
left of the monitor and the camera pans round. To move the
view up, the surgeon looks to the top of the monitor and
the camera follows. Movement only occurs if the surgeon is
simultaneously pressing a footswitch, thus allowing unrestricted
head movements at all other times.
As the system is controlled by head movements,
does this mean that I can’t otherwise move my head during the
Not at all, movement of the endoscope
only occurs when the surgeon presses the foot pedal, therefore
allowing unrestricted head movements at all other times.
When using EndoAssist am I constrained by cables,
or otherwise restricted in my position around the operating table?
The headband and emitter used
with EndoAssist are wireless, so you are free to move around
the table at will.
Will EndoAssist work my existing endoscope and
EndoAssist has been designed
to work with all commonly used 5mm and 10mm diameter endoscopes.
I use a 30 degree scope for most of my procedures,
can this be used with EndoAssist?
EndoAssist is ideal for use with
both zero and 30 degree endoscopes.
What Range of Movement does the EndoAssist allow?
The EndoAssist provides the widest range
of movements to cope with the varying anatomy of your patient.
Pan movement: 350 degrees
Tilt movement: +90 to –45 degrees
Zoom length: 240mm
How long does it take to set up the system for
No user-specific setup is required
to use EndoAssist.
How long does it take to set up the system before
It takes less than 2 minutes
to set-up EndoAssist prior to surgery. Wheel the system into
the operating room, plug in and switch on. The systems will
automatically perform a self test, following which it is
immediately available for use.
We have a number of operating rooms used for minimal
access surgery. How easy is it to move EndoAssist between them?
Because the system is free-standing,
one person can easily wheel it between operating rooms. Time
consuming assembly or mounting to the operating table is
How does EndoAssist maintain sterility in the surgical
The endoscope holding arm is
detachable and should be sterilised along with your other
surgical instruments. The EndoAssist boom is sufficiently
high above the field that it generally does not require draping.
However, a drape is available for purchase if required.
I sometimes need to clean the endoscope lens and
so need to quickly withdraw it from the port. How can I quickly achieve
this with EndoAssist?
The Quick Fit Laparoscope Mounting
allows the surgeon to “snap-fit” the scope to
the holding arm. Scope cleaning is therefore fast and simple.
How does the system define and maintain the position
of the entry point?
EndoAssist includes laser-locators
that enable the user to accurately position the goniometric
point at the entry port. This ensures smooth scope movement.
Will using EndoAssist force me to change patient
position, or the ports that I use?
The very large range of movement
possible with EndoAssist accommodates the widest range of
patient sizes and orientations: including morbidly obese
patients and supine approaches. Because the holding-arm approaches
from above, you will not need to change your camera port
position when using the system.
What are the running costs of the product, are
there consumables involved?
The running costs of EndoAssist
are negligible. The only consumable items required are the
Head Tracker batteries, a standard item available from most
What regulatory approvals apply to the EndoAssist?
The CE mark affixed to EndoAssist indicates
