Electromechanical device for injection for medical use and actuated by a trigger.

摘要

The invention relates to an electromechanical device of the injection. & br / & it comprises a frame (1) having the general shape of a gun with a handle (2) and receiving a movable carriage (3) for a removable syringe (4) with needle (5) and the piston (6), at least one element motor actuating a button (8) which acts against the piston (6) of the syringe and a cradle (9) support of the syringe (4) mounted on the movable carriage (3), itself actuated by a motor element, the front part of the gun is provided with a stabilizing pattern (10) of the skin, which guide and ensure the degree of penetration of the needle (5) by an adjusting wheel, which makes it possible to adjust the depth of the input of the fixing end of the pattern (10), characterized by the fact that the electric motor (7) which actuates the piston (6) of the syringe (4) is integral with the movable carriage (3), its axis, actuates a set of gear (14, 15) mounted on said movable carriage (3); the other electric motor (12) fixed to the frame (1) are, for its axis (30), on a set of cams (26, 29) which drives the movements of the movable carriage (3). br / the invention applies in particular for mesotherapy.
