摘要： A device (1; 1') for treating the ligamentum flavum by radio frequency comprises:
a hand grip (2; 2') to be held by an operator;
a cannula (10; 10') fixed at its proximal end (31) to the hand grip (2; 2') and extending longitudinally from said hand grip (2; 2') to an opposed distal end of the cannula (10; 10'), designed to reach the ligamentum flavum;
at least one electrode (11; 11') which is electrically connectable to a radio frequency generator and is slidably housed in the cannula (10; 10');
the cannula (10; 10') being provided with a hole (13) to allow the electrode (11; 11') to emerge from the cannula (10; 10');
an actuating device (26; 26') of the electrode (11; 11') provided in the hand grip (2; 2') for moving the electrode (11; 11'), wherein
the actuating device (26; 26') comprises a slider (28; 94) along a sliding guide (27; 27') having a first (29; 91) and a second (30; 90) sliding portion placed in succession, the first portion (29; 91) being shaped so as to allow an axial translation of the slider (28; 94) along the guide (27; 27') to generate a consequent translation of the electrode in the cannula (10; 10'), the second portion (30; 90) being configured so as to allow a rotational translation of the slider (28; 94) along the guide (27; 27') so as to generate a corresponding rotational translation of the electrode (11; 11') outside the cannula (10; 10').
