I. C. Medical · Model 360
The Crystal Vision 360 are in a class by themselves when used during open procedures. A patented sensor system turns the evacuator on and off when the surgeon activates the electrosurgical laser, argon beam coagulator, or other smoke producing instrument. The Crystal Visions are very easy to live with in the operating room. They are small, weigh about seventeen pounds, and are very quiet. Most O.R staffs simply slip the Crystal Vision onto a shelf on the electrocautery cart. The 360 automatically stops the vacuum pump if tissue is trapped in the evacuation tube. The evacuators automatically restart when the tissue, or other obstruction is cleared from the tube. Both models automatically tell the operator when to replace the input filter. This reduces procedural costs, eliminates guessing, and provides for the best removal of smoke from the surgical site. A pneumoperitoneum is created during laparoscopy by inflating the abdominal cavity with carbon dioxide gas from an insufflator. The inflation allows the surgeon to see better and creates a much safer operating environment for the patient. Leaks in the instruments and suctioning of fluids (and gas) decreases the carbon dioxide in the abdomen. The insufflator senses the lower pressure and adds more gas. Surgeons frequently rest their arm or actually lean on the patient. This can cause the pressure in the pneumoperitoneum to increase above safe levels but the insufflators cannot reduce the pressure because they are only designed to add gas to the abdomen.
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Symptoms: Plume not captured, weak airflow, blower ramps but flow is low.
Root cause: Loaded ULPA / charcoal filter, a worn blower / turbine, or a leak / kink in the hose.
Symptoms: Filter-change alarm, reduced airflow, odour breakthrough.
Root cause: ULPA / activated-charcoal filter at end of its capacity.
Symptoms: Evacuator does not start with the ESU, or runs continuously.
Root cause: The ESU-sensing cuff / cable or the auto-activation board.
Symptoms: Noisy, weak, or dead blower even with a new filter.
Root cause: Worn blower / turbine bearings or motor.
Symptoms: Very loud in use, speed will not adjust.
Root cause: Worn blower or a speed-control fault.
