Abstract

A rapid pulsatile smoke extraction system includes a laser handpiece having a sleeve configurable to be applied to tissue; a vacuum pump and a vacuum reservoir; a conduit connecting the reservoir with the sleeve; and a valve inserted in the conduit. A volume of the vacuum reservoir is at least two times larger than a volume of the sleeve, such that operation of the valve supports instantaneous evacuation of smoke and particulate products from the sleeve into the vacuum reservoir.

Claims (10)

1. A rapid pulsatile smoke extraction system comprising:

a laser handpiece including a sleeve configurable to be applied to tissue;

a vacuum pump and a vacuum reservoir;

a conduit connecting the reservoir with the sleeve; and

a valve inserted in the conduit,

wherein a volume of the vacuum reservoir is at least two times larger than a volume of the sleeve, such that operation of the valve supports instantaneous evacuation of smoke and particulate products from the sleeve into the vacuum reservoir,

wherein the valve is constructed and arranged to open communication between the sleeve and the vacuum reservoir just prior to start of a laser pulse and to close communication between the sleeve and the vacuum reservoir just after end of a laser pulse.

2. The system of claim 1 , wherein the sleeve is a removable sleeve or disposable sleeve.

3. The system of claim 1 , wherein the sleeve, when applied to tissue, is constructed and arranged to form a controlled volume.

4. The system of claim 1 , wherein the sleeve is one of a group of sleeves consisting of a rigid sleeve and a flexible sleeve.
