Section 1.0
1.1 Introduction
Indications for use for the VisiClear™ Surgical Smoke Plume Evacuator include:
To remove and lter smoke and aerosols from a surgical site produced during electrosurgical
and laser procedures.
e VisiClear™ Surgical Smoke Plume Evacuators have been designed with a vacuum motor.
e motor is used to draw the surgical smoke from the surgical site through the vacuum
tubing and into the VisiClear™ lter where the surgical smoke is processed by a series of
lters. A single disposable lter is used to simplify the installation and removal during lter
changes. e lter is completely enclosed to protect the healthcare personnel from potential
contamination during lter changes. One BUFFALO FILTER® VisiClear™ lter contains four
dierent stages within to capture the smoke plume.
e rst stage ltration is a prelter whose function is to trap and remove gross particulate.
e second stage ltration is ULPA grade (Ultra Low Penetration Air) lter whose high-tech
patented (U.S. Patent #5874052) design captures particulates and micro-organisms from
.1 to .2 microns at an eciency of 99.999%.
e third stage ltration is comprised of virgin activated carbon.
e fourth stage ltration is a woven berglass ltration media used to reduce the amount of
activated carbon nes from migrating out of the lter.
e electronic controls on the face panel of the VisiClear™ Surgical Smoke Plume Evacuator has
been designed “user friendly” and facilitate unit set up and operation. Please refer to Section
