Patent ID: 7604630

Claim:
An applicator attachable to a skin treatment device, which is capable to apply RF energy and optic energy simultaneously for treating a patient's skin, the attachable applicator comprising: a housing ( 11 ) having a first mounting block ( 41 ) with a rear flange ( 41 b ) and a second mounting block ( 43 ) with a front annular groove ( 43 a ), wherein said first mounting block ( 41 ) consists of a tube plug ( 5 l a ) having a first flow path ( 51 ) connected to a lateral vacuum pocket ( 25 ), said second mounting block ( 43 ) consists of an extension tube ( 53 a ) having a second flow path ( 53 ) for connecting to the first flow path ( 51 ) of the tube plug ( 51 a ), so that the rear flange ( 41 b ) of the first mounting block ( 41 ) is elastically coupled to the front annular groove ( 43 a ) of the second mounting block ( 43 ) for easily mounting to or off each other, an electrode ( 14 ) installed at a center of the housing ( 11 ) along with a longitudinal direction of an axis for generating high frequency radiation, so that said electrode ( 14 ) will be located above a swollen up skin, a capsule ( 23 ) forming a suction cavity ( 16 ) at an inlet portion, a lateral air-flow passage ( 21 ) and lateral vacuum pocket ( 25 ) disposed around the capsule ( 23 ) for sucking out the air from the suction cavity ( 16 ) to an inner chamber ( 17 ) being maintained a negative pressure by a vacuum unit, so that said capsule ( 23 ) is attached to or detached from said housing ( 11 ) for replacing different kind of capsule during the skin treatment, and a cooling unit ( 15 ) for removing excessive heat generated by the electrode ( 14 ) far maintaining a moderate treating temperature, wherein said cooling unit ( 15 ) has arranged a thermocouple ( 15 a ), which is tightly surrounding a pair of electrodes ( 14 ) and a cooling block ( 15 b ), which is tightly surrounding the thermocouple ( 15 a ).
