Medical laser device for medical applications requiring critical safety has a user-controlled handling unit affected by a switching unit with an on-/off-foot switch

摘要

A switching unit (2) has an electrodynamic piezoelectric element (4) affected by an on-/off-foot switch (3) for generating signals for switching on and off. Gained in the electrodynamic piezoelectric element during operation of the on- /off-switch, electric energy is used for wireless transmission of the signals for switching on and off to a user-controlled handling unit (1).
