A novel handpiece and system for abrasion of skin is disclosed. A short handpiece with a threadably removable tip is used. The opening in the tip is centered on the handpiece axis and a small diameter particle inlet channel and larger diameter outlet channel are both offset from the handpiece axis.

A novel handpiece and system for abrasion of skin is disclosed. A short handpiece with a threadably removable tip is used. The opening in the tip is centered on the handpiece axis and a small diameter particle inlet channel and larger diameter outlet channel are both offset from the handpiece axis. A central blade or barrier within the tip divides the tip into two volumes which each communicate with the opening and respective ones of the inlet and outlet passages. A vacuum control opening is formed in the tip for easy control by the operator. Abrasive particles and removed tissue are applied to the interior of a cylindrical filter supported within a supporting container. The annular area between the container and this filter is connected through a secondary emergency filter to a vacuum pump. The cylindrical filter can be a flexible filter bag. A large source of abrasive particles is coupled to the handpiece inlet and the filter is coupled to the handpiece outlet.

[ What is claimed is:] [1.]1. A handpiece apparatus for skin abrading equipment; said handpiece apparatus comprising:a body member elongated in the direction of a central axis and having a removable tip at one end thereof; said removable tip having an outlet opening which is coaxial with said central axis;said body member having first and second channels therethrough which are respectively connectable to a first conduit and a second conduit, said first channel and said first conduit being operative to conduct a stream of abrasive particles toward said removable tip and said second channel and said second conduit being operative to conduct said particles and abraded skin away from said removable tip;at least a portion of the interior of said removable tip forming a vacuum chamber between an end of said body member and said outlet opening when said outlet opening is sealed against the skin to be abraded;and a barrier extending fully across the interior of said removable tip from a position adjacent said outlet opening to a position adjacent the end of said body member to separate the flow of said abrasive particles toward and away from said removable tip.
