Abstract
The apparatus is usable to remove surface portions of human tissue in an adjustable manner and essentially comprises a tool provided with a supply tube along which abrasive reducing substances are conveyed under pressure. A throughhole in the head disposed along the axis of the tube permits the substances to abrade the region of tissue facing the hole. A collection tube in which is created a depression is provided for the purpose of removing under suction both the reducing substances and the portions of tissue removed during the treatment.
Claims12
A hand tool for removing surface portions of human tissue by superficial abrasion caused by a stream of a mixture of air with at least one granular abrasive substance striking on the surface of the tissue to be removed, said tool comprising an elongated manipulative body (20), a supply tube (25, 33) for said mixture, a collection tube (26, 31) for the purpose of sucking-in both said mixture and the removed portions of said tissue, each one of said tubes (25, 33;
- 26, 31) having a terminal portion (33, 31) with a free end, and an operating head (21) secured to said manipulative body (20) at the distal end thereof and housing said terminal portions (33, 31), said body (20) housing the other portion (25, 26) of said tubes (25, 33;
- 26, 31), said head (21) having a longitudinal axis and being provided with a wall (23) having a wall portion inclined and offset with respect to the said axis, a throughhole (22) being provided in said wall portion and internally communicating with said free ends of said terminal portions (33, 31), said throughhole (22) being aligned with said terminal portion (33) of said supply tube (25, 33) so that, by keeping in contact said throughhole (22) with said surface, said stream of mixture travelling through the terminal portion (33) of said supply tube (25, 33) and said throughhole (22) is caused to strike said surface with an inclined incident angle.
Apparatus for removing surface portions of human tissue by superficial abrasion caused by a stream of a mixture of pressurized air with at least one granular abrasive substance striking on the surface of the tissue to be removed, comprising a hand tool (5) to be applied to said surface, first supply means (2) for supplying said pressurized air, second supply means (3) for supplying said abrasive substance, suction means (4), said tool (5) comprising an elongated manipulative body (20), a supply tube (25, 33) for conveying said mixture, duct means for conveying said mixture from said first and second supply means, a collection tube (26, 31) for the purpose of sucking-in both said mixture and the removed portions of said tissue, each one of said tubes (25, 33;
- 26, 31) having a terminal portion (33, 31) with a free end, the other portion end of said supply tube (25, 33) being connected to said duct means and the other end of said collection tube (26, 31) being connected to said suction means (4), and an operating head (21) secured to said manipulative body (20) at the distal and thereof and housing said terminal portions (33, 31), said body (20) housing the other portion (25, 26) of said tubes (25, 33;
- 26, 31), said head (21) having a longitudinal axis and being provided with a wall (23) having a wall portion inclined and offset with respect to said axis, a throughhole (22) provided in said wall portion and internally communicating with the free ends of said terminal portions (33, 31), said throughhole (22) being aligned with the terminal portion (33) of said supply tube (25, 33) so that, by keeping in contact said throughhole (22) with said surface, said stream of mixture travelling through the terminal portion (33) of said supply tube (25, 33) and said throughhole (22) is caused to strike said surface with an inclined incident axis.
