Suction Pinch Valve
When closed, the valve pinches off suction flow to the handpiece:
• When priming the irrigation system
• When pressing the Fast Flush pedal
• In Run Status, when you release the Vibration pedal. In this case, the pinch
valve closes for about one second, then re-opens.
• In Lap Mode, when you release the Vibration pedal. This suction stoppage
prevents depletion of the pneumoperitoneum.
The suction pinch valve default position (system off) is closed. If the System has
been running, when you turn the Power Switch off, the suction pinch valve
remains open until the drain cycle has finished, then closes. A button on the front
of the suction pinch valve allows you to open the valve manually.
System Power Switch
Turning this switch on ( | ) activates all system components and begins filling the
handpiece with cooling water. Turning this switch off ( ) activates the cooling
water drain cycle. When the system has drained water from the cooling water
system (about one minute), it automatically deactivates all system components.
Irrigation Pump Head
A latch rotates from right to left to open the pump head, and from left to right to
close. When open, it allows you to place irrigation tubing into the peristaltic
pump. Closed, the pump head holds irrigation tubing against the peristaltic pump.
Contamination Guard
The guard is hydrophilic and
becomes blocked when wet.
Protects the vacuum pump from particulate matter and moisture in the suction
stream. It is necessary to replace the contamination guard every six months or
when it becomes blocked.
Retaining Bail for Suction Canister
The bail holds the suction canister in place on the shelf.
Caution
To avoid injury to surgical personnel, keep fingers away from the suction pinch valve.
