<p>The linear scanning system for treating skin tissue by pulse laser according to the invention solves the problem of linear shifting of the laser beam with the possibility of homogeneous and even covering of larger uneven skin surfaces for treatments of skin. The linear scanning system is made in such a way that the computer program, stored in the (CPE) unit, sends a computer signal to activate the laser (L) and at the same time the motor (M) featuring a reduction gear (R) with the first Hall sensor (HS1) for detecting the initial scanning position and the second Hall sensor (HS2) for detecting the final scanning position when the foot switch (NS) is activated. The limit switch (KS) consists of Hall sensors (HS1 and HS2) and a magnet (MAG) inside the eccentric (E). On the reduction gear (R) axis there is an eccentric (E) featuring a lever (V) with ball bearings (KL) and a rotating cylinder (VA) featuring a fixed mirror (Z) being focused by the laser beam from the focusing lens (5). Due to the displacement of the eccentric (E) and the mirror (Z) from initial to terminal position of the limit switch (KS), the laser beam produces with respect of the height of the spacer (6) a straight thinner or broader line.</p> |
