<p>The present invention relates to a handpiece tip comprising: an external container (110) in which a downwardly opened through-hole (111) is formed in a length direction; an inner pipe (120) closing the inlet of the through-hole (111) of the external container (110), separated from the ceilings (111c, 111d) of the through-hole (111) facing the inlet thereof, partially closed on the inner circumferential surface of the through-hole (111), co-axially inserted and installed in the through-hole (111), dividing the through-hole (111) into a first hollow part (111a) which is the bottom space of the adhered part and a second hollow part (111b) which is the top space of the adhered part, and having a feeding path (121) penetrating therein to be connected with the second hollow part (111b); a supplying hole (112) formed in the external container (110) to be connected with the first hollow part (111a); a spraying hole (123) formed to penetrate through a front end part (122) of the inner pipe (120) by being connected with the first hollow part (111a) so as to spray supplied liquids onto skin (S); and a discharging hole (113) formed to penetrate through a side surface (110b) of the external container (110) and to be connected with the second hollow part (111b) so that air for vacuum absorption and residues or liquids after a skin procedure can be discharged. By means of the present invention, the supply of liquids and the absorption of residues after a procedure can be co-axially performed so that a product can be miniaturized and production costs can be reduced.</p> |
