Abstract
The invention relates to a dental treatment instrument with which a dental handpiece (1), at its instrument end and/or at its hose end, is provided with unlocking planes (4a, 4b) which cooperate with correspondingly complementarily formed unlocking planes (5a, 5b) of a dental treatment instrument (2) or of a hose connection (3) of a supply hose. The treatment instrument (2) or the supply hose (3) can, because of the cooperating unlocking planes (4a, 4b; 5a, 5b), be released by simple turning of the treatment instrument (2) or of the supply hose (3) relative to the dental treatment instrument.
Claims23
Dental handpiece (1), which at one end thereof can be coupled with a dental treatment instrument (2) and at an opposite end thereof can be connected to a supply hose (3) for the delivery of at least one operating medium serving for the operation of the dental treatment instrument, characterized in that, the dental handpiece (1) has an unlocking plane (4a) at its instrument connecting end and an unlocking plane (4b) at its hose connecting end each running obliquely to the longitudinal direction of the dental handpiece, each of which plane is respectively formed complementary to an obliquely running unlocking plane (5a, 5b) of the dental treatment instrument (2) and of a hose connection of the supply hose (3).
Dental treatment instrument (2), which can be plugged on to a dental handpiece (1), characterized in that, the dental treatment instrument (2) has at its handpiece end an unlocking plane (5a) which runs obliquely to the longitudinal direction of the dental treatment instrument, and which is formed complementary to an obliquely running unlocking plane (4a) of the dental handpiece (1).
Supply hose (3), which on the one hand can be plugged on to a dental handpiece (1) and on the other hand can be connected to a control device (12) for controlling the delivery of operating medium via the supply hose to the dental handpiece, characterized in that, a handpiece end hose connection of the supply hose (3) has an unlocking plane (5b) which runs obliquely to the longitudinal direction of the hose connection and which is formed complementary to an obliquely running unlocking plane (4b) of the dental handpiece (1).
