Laser device, hand-piece and method for lipolysis

A device for laser lipolysis;

• wherein the device comprises:
• at least one treatment laser source adapted to emit radiation within a wavelength range strongly absorbed by human body adipocytes;
• a hand-piece comprising a handle and a cannula adapted to be inserted into the adipose tissue of a patient undergoing a lipolysis treatment;
• an optical fiber adapted to connect the treatment laser source to the hand-piece, the cannula being adapted to receive a distal portion of the optical fiber;
• a detection system for detecting the movement speed of the hand-piece when in use;
• a control unit, functionally coupled to the treatment laser source and adapted to control at least one emission parameter of the treatment laser source, configured to modulate the power emitted by the treatment laser source based on the movement speed of the hand-piece detected by the detection system;
• a visual signaling system adapted to signal an anomalous speed condition to an operator, wherein the visual signaling system comprises at least one first aiming light source adapted to inject a first light beam into the optical fiber, the first light beam being visible through tissues in which the cannula and the optical fiber are inserted, wherein the control unit is configured to control the first aiming light source based on the detected movement speed of the hand-piece to provide an operator with information on the movement speed of the hand-piece.
