Abstract
Disclosed is a medical apparatus including at least one electrode for generating cold plasma, the electrode including a tail and a head and being covered with isolating and biocompatible mineral material, the tail being the electrode portion to be connected with the corresponding handpiece and the head being the electrode portion to be faced towards the skin of the patient, the apparatus including at least one electrode including a head including a spherical end and/or at least one electrode including a head shaped to form a corkscrew-like element.
Claims22
Apparatus externally comprising:
- at least one mechanical structure for the containment and electromagnetic screening, and internally comprising:
- a first unit (1) comprising:
- at least one color LCD display with touch screen and accessible from a front panel of said apparatus;
- a second unit (2) comprising:
- at least one logic card in turn containing a microprocessor (11) with memory (10) for resident programs, at least one DDS (12) adapted to generate RF signals preset according to need, at least one modulator-attenuator (13) controlled by the microprocessor (11) and generating pulses, at least one ON-OFF function, at least one system for the adjustment of intensity of the output radiofrequency of the entire machine, at least one amplifier (14) adapted to restore the losses of said modulator-attenuator (13), and at least one low-pass filter (15) adapted to limit the band to the desired one, said radio frequencies being comprised between 1 MHz and 15 MHz;
- said medical apparatus further internally comprising a third unit (3) comprising:
- at least one pre-driver and at least one RF broadband power amplifier for the signals coming from said second unit (2) up to a power of 200 watts;
- a fourth unit (4) comprising:
- at least one RF power filter inserted by the microprocessor (11) depending on the frequency generated by the DDS (12);
